Anatomic footprint of the direct head of the rectus femoris origin: cadaveric study and clinical series of hips after arthroscopic anterior inferior iliac spine/subspine decompression.

Abstract

PURPOSE:

The purposes of this study were to define the anatomy of the anterior inferior iliac spine (AIIS) and its relation to the footprint of the rectus femoris tendon and to evaluate on the clinical outcomes after AIIS/subspine decompression.

METHODS:

The rectus origin was dissected and detached in 11 male cadaveric hips with a mean age of 54.3 ± 14.3 years (range, 33 to 74 years). The proximal-distal and medial-lateral extent of the footprint and its relation to the AIIS and acetabular rim were evaluated, with the 12-o'clock position defined as directly lateral at the insertion of the indirect head of the rectus tendon and the 1- to 6-o'clock positions defined as anterior acetabular positions. To assess the safety and efficacy of subspine decompression for AIIS deformity, clinical correlation of a series of 163 AIIS decompressions (mean age, 27.8 years; age range, 14 to 52 years) performed from January 2011 to January 2012 was completed, and outcome scores, strength deficits, and ruptures were assessed by manual muscle testing and postoperative radiographs. All patients presented with symptomatic FAI with proximal femoral and/or acetabular deformity and type 2 (131 hips) or type 3 (32 hips) AIIS morphology as defined by Hetsroni et al.

RESULTS:

The mean proximal-distal and medial-lateral distances for the rectus origin footprint were 2.2 ± 0.1 cm (range, 2.1 to 2.4 cm) and 1.6 ± 0.3 cm (range, 1.2 to 2.3 cm), respectively. There was a characteristic bare area at the anteromedial AIIS. On the clock face, the lateral margin (1-o'clock to 1:30 position) and medial margin (2-o'clock to 2:30 position) of the AIIS and the indirect head of the rectus (12 o'clock) were consistent for all specimens. In the clinical series, 163 AIIS decompressions were performed for symptomatic subspine impingement. The mean modified Harris Hip Score was 63.1 points (range, 21 to 90 points) preoperatively compared with 85.3 points (range, 37 to 100 points) at a mean follow-up of 11.1 ± 4.1 months (range, 6 to 24 months) (P < .01). Short Form 12 scores improved significantly from a mean of 70.4 (range, 34 to 93) preoperatively to a mean of 81.3 (range, 31 to 99) postoperatively (P < .01). The mean pain score on a visual analog scale also improved significantly from a mean of 4.9 (range, 0.1 to 8.6) preoperatively to a mean of 1.9 (range, 0 to 7.8) postoperatively (P < .01). The mean alpha angle improved from 61.5° (range, 35° to 90°) preoperatively to 49° (range, 35° to 63°) postoperatively on anteroposterior radiographs and from 71° (range, 45° to 90°) preoperatively to 44.3° (range, 37° to 60°) postoperatively on lateral radiographs. No short- or long-term hip flexion deficits or rectus femoris avulsions were noted with up to 2 years' follow-up.

CONCLUSIONS:

The origin of the rectus femoris tendon is broad on the AIIS and protective against direct head detachment with subspine decompression. This broad origin and consistent bare area anteromedially on the AIIS can be readily used by surgeons to perform a safe AIIS resection in cases of symptomatic impingement. Arthroscopic subspine decompression in addition to osteoplasty for symptomatic cam- and/or pincer-type FAI deformities can reliably improve outcome scores without significant hip flexion deficits or AIIS/rectus femoris avulsions.

CLINICAL RELEVANCE:

The direct head of the rectus tendon has a broad insertion on the AIIS, and an area devoid of tendon provides a "safe zone" for subspine decompression in cases of symptomatic AIIS impingement.

New Study: The Use of PRP in Ligament and Meniscal Healing

New Study: The Use of PRP in Ligament and Meniscal Healing
by TOBI Faculty, Jason Dragoo MD

Steven SampsonFounder, President at The Orthohealing CenterContribuidor principal

Platelet Rich Plasma has quickly emerged as a wide spread treatment for acute and chronic musculoskeletal disorders, such as tendinopathies and arthritis. However, a recent study out of Sports Medicine Arthroscopy, summarizes an emerging trend amongst PRP researchers: the application of PRP for meniscus and ligament healing.

Recent clinical studies support the potential benefit of PRP in Anterior Cruciate Ligament allograft maturation, while some animal studies suggest PRP effects on primary ACL repair. However, no randomized controlled trials have yet to exhibit benefits in PRP for ACL tendon allograft-tunnel integration.
The use of Platelet Rich Plasma for meniscus repair is much less documented in comparison to ligaments. This review article found only two studies which documented the application of PRP for meniscal healing. The compilation of studies incorporating PRP in ligament and meniscus treatment provided promising evidence for Platelet Rich Plasma application in primary ACL repair in skeletally immature patients, ACL graft maturation, and repair of meniscal tears in avascular zones. This area of PRP research is vastly unexplored and reveals much potential for future advancement in PRP treatment options.

The use of PRP in ligament and meniscal healing.

Abstract

Platelet-rich plasma (PRP) has become a popular treatment for acute and chronic soft tissue injuries. Although the majority of research has focused on its use in tendinopathy, PRP may have potential in meniscus and ligament healing. Some level II studies support a possible benefit for anterior cruciate ligament (ACL) allograft maturation, and preliminary animal studies point to a potential role for PRP in primary ACL repair. However, randomized controlled trials have not demonstrated a benefit of PRP for ACL tendon allograft-tunnel integration. To date, 2 studies document the use of PRP for meniscal applications, but this field is largely unexplored. With respect to ligament and meniscal applications, the current literature suggests PRP may be promising for primary ACL repair in skeletally immature patients, ACL graft maturation, and repair of meniscal tears in the avascular zone.

Operaron a Juan Falcón y Hugo Soto del Zamora FC y seran bajas por 40 días

http://www.balonazos.com/ve/index.php/2013-08-19-19-49-54/noticias/9327-operaron-a-juan-falcon-y-hugo-soto-del-zamora-fc-y-seran-bajas-por-40-dias




El atacante nacional Juan Falcón y el defensor colombiano Hugo Soto, ambos del Zamora FC, fueron operados tras sufrir molestias antiguas que los aquejaban partido a partido. El Doctor titular del conjunto zamorano, Rafael Viloria, explicó la situación en primera instancia del central colombiano Hugo Soto “Soto fue intervenido en su rodilla derecha, tras una lesión meniscal, se decidió realizar una artroscopia de rodilla. Que fue dirigida por mi persona en la Centro Clínico Varyna, en un tiempo de una hora, sin ninguna irregularidad y que ahora le permitió regresar a Cartagena- Colombia donde llevará acabo una parte de su recuperación”.

Por otro lado el goleador de la “furia llanera” Juan Falcón, también fue intervenido de su tobillo izquierdo, en lo que el mismo declaró como “una operación planificada”. Al respecto, Viloria soltó que “Juan tuvo que recibir una Artroscopia de Tobillo, para suturar una lesión osteocondral. La operación fue llevada a cabo en el Centro Clínico Mérida por el Doctor Antonio Torres un cirujano especializado en lesiones de pie y tobillo. Gracias a Dios todo ocurrió sin ninguna complicación y desde hoy mismo (miércoles) podrá reintegrarse con el grupo acá en Barinas para iniciar su rehabilitación”.

Al respecto de la recuperación de ambos jugadores, el especialista del actual monarca del fútbol venezolano, comentó que “son cirugías bastante sencillas, por lo que ambos jugadores sólo deberán cuidarse y tomar las medidas necesarias para llevar la recuperación lo más pronto posible. Estimamos que en un tiempo estipulado de unos 30 a 40 días ambos podrán volver a las canchas”.

Does Arthroscopic Débridement With or Without Interposition Material Address Carpometacarpal Arthritis?

Julie E. Adams MD
Symposium: Thumb Carpometacarpal Arthritis
Online First ™ - March , 2013

Abstract

Background

Thumb carpometacarpal (CMC) joint arthritis is a common problem in clinical practice with a variety of treatment options. Arthroscopic procedures can preserve all or part of the trapezium in the setting of treatment of basilar joint arthritis, and such procedures (even without stabilization or ligament reconstruction) have high reported success rates. However, little is documented about the limitations of these procedures in terms of patient selection, the optimal type of interposition, if any, and rehabilitation.

Questions/purposes

A systematic review was performed to determine the influence of (1) interposition material (manufactured, biological, or none); and (2) patient-related factors (including metacarpophalangeal joint hyperextension, ligamentous laxity, and severity of arthritis) on pain, functional scores, and postoperative complications unique to each approach.

Methods

A systematic review of the English language literature regarding thumb basilar joint arthritis and arthroscopic partial trapeziectomy or débridement was performed. Those procedures including ligament reconstruction or stabilization were excluded.

Results

Biological materials and no interposition were both associated with satisfactory improvement and low rates of complications; complication rates with synthetic materials were higher. Eaton Stages I to III were treated successfully with this technique. The effect of scaphotrapeziotrapezoid (STT) changes was variably described across series. In most series, metacarpophalangeal hyperextension did not seem to have an adverse effect on outcomes, although these patients were excluded in some series.

Conclusions

Arthroscopic débridement with or without interposition can be used for treatment of Eaton Stages I to III CMC osteoarthritis with satisfactory outcomes. Some series suggest satisfactory outcomes in the setting of STT changes and metacarpophalangeal hyperextension.

Abstract

PURPOSE:

This study aimed to compare the arthroscopic patch graft procedure and partial repair for irreparable large or massive rotator cuff tears (RCTs) in shoulders with low-grade fatty degeneration of the infraspinatus (stage 1 or 2 according to Goutallier et al.) in terms of the functional and structural outcomes.

METHODS:

This study included 24 patients who underwent the patch graft procedure (group A) and 24 patients who underwent partial repair (group B) for irreparable large or massive RCTs. Clinical outcomes were evaluated at a mean of 35.5 months postoperatively in group A and 35.7 months in group B.

RESULTS:

The clinical findings were significantly improved at the final follow-up in both groups (P < .001). A significant difference was found between groups A and B in terms of postoperative Constant and American Shoulder and Elbow Surgeons scores (P = .001 and P = .021, respectively). There was a significant difference in the retear rate for the infraspinatus tendon (ISP) between the 2 groups (2 patients [8.3%] in group A v 10 patients [41.7%] in group B, P = .015). At the final follow-up, there was a significant difference in the affected side-versus-unaffected side muscle strength ratios for abduction and external rotation between group A and group B (P < .001 for both). Shoulders with retears of the ISP showed significantly inferior clinical outcomes compared with those without retears (P < .001).

CONCLUSIONS:

In arthroscopic surgery for irreparable large or massive RCTs with low-grade fatty degeneration of the infraspinatus, the patch graft procedure showed an 8.3% retear rate for the repaired ISP with both improved clinical scores and recovery of muscle strength, whereas the partial repair had a retear rate of 41.7% (P = .015).

Abstract

PURPOSE OF REVIEW:

To examine recent trends in the use of arthroscopic surgical techniques to address musculoskeletal problems. The review is particularly timely given the rapidly expanding range of indications for diagnostic and therapeutic arthroscopic procedures involving virtually every peripheral joint.

RECENT FINDINGS:

We focus on arthroscopic approaches to problems of the hip, wrist, elbow and ankle. Hip arthroscopy is permitting novel, minimally invasive approaches to the management of femoral acetabular impingement, labral tears, loose bodies and chondral lesions. Wrist arthroscopy has provided novel approaches to ligament tears, synovitis and fractures. Ankle arthroscopy has been especially helpful with soft tissue impingement syndromes, synovitis and fracture. Elbow arthroscopy has been especially helpful in the management of synovitis and osteoarthritis due to osteophytosis. Complications of arthroscopic procedures occur very rarely. Virtually all the literature on arthroscopy outcomes comes from small uncontrolled studies.

SUMMARY:

Arthroscopy provides a safe alternative to arthrotomy in the management of a wide range of clinical problems. The generally weak designs of studies performed to date compromises the strength of recommendations that can be made about the role of these procedures in clinical practice.

Más de 250 traumatólogos debaten los últimos 

avances en artroscopia de rodilla. 

 
Ricardo Cuéllar: “La artroscopia, como medio de tratamiento, constituye un avance consolidado en la patología de rodilla”.


- Expertos de toda España se reúnen los días 23 y 24 de febrero en la capital guipuzcoana con motivo del II Curso de Cirugía Artroscópica básica y el III Curso de Cirugía Artroscópica Avanzada de Rodilla

- El encuentro se organiza con el patrocinio científico del Hospital Universitario Donostia. Policlínica Gipuzkoa será la sede de las sesiones quirúrgicas

- El Curso versará sobre tres tipos de lesiones: menisco, cartílago y ligamentos cruzados. Se realizarán cirugías en espécimen de cadáver; ello permitirá mostrar el abordaje de lesiones por otro lado más difíciles de encontrar


Donostia-San Sebastián, febrero de 2012.- Más de 250 traumatólogos de toda España se darán cita a partir de hoy, días 23 y 24 de febrero en el Auditorio del Parque Tecnológico de San Sebastián, para debatir sobre los últimos avances de la técnica artroscópica de rodilla así como abordar tres tipos de lesiones: las meniscales, las de cartílago y las de los ligamentos cruzados. 

El II Curso de Cirugía Artroscópica básica y el III Curso de Cirugía Artroscópica Avanzada de Rodilla los organiza el Departamento de Cirugía Ortopédica y Traumatología del Hospital Universitario Donostia, presidido por el traumatólogo Ricardo Cuéllar junto con su Jefe del Servicio, Jaime Usabiaga. Policlínica Gipuzkoa, copatrocinador de los cursos, será sede de las sesiones quirúrgicas. 

Durante las jornadas, como novedad, se realizarán cirugías en espécimen de cadáver, “para poder presentar los diferentes tipos de técnicas quirúrgicas que no siempre son fáciles de encontrar en pacientes reales en las fechas requeridas. En ellos, se abordarán tres clases de lesiones: las meniscales, las del cartílago y las de los ligamentos cruzados”, detalla el traumatólogo Ricardo Cuéllar, uno de los mas conocidos especialistas en el tratamiento de estas patologías. 

Según explica Ricardo Cuéllar, la artroscopia “es una vía para realizar una cirugía de forma menos agresiva y, actualmente, para el tratamiento de muchas patologías de rodilla, nadie se plantea realizar cirugía abierta. Se puede considerar como un avance consolidado”. 

Entre las técnicas referidas al tratamiento de la patología meniscal, “se hará una demostración de sutura meniscal, implante de menisco artificial y trasplante meniscal -colocación del menisco obtenido de banco de tejidos a partir de donante-, técnicas que pocos equipos realizan en España y que los asistentes tendrán ocasión de presenciar durante los cursos. 

Las mesas de debate, en las que intervendrán numerosos especialistas, se centrarán en otros dos puntos de discusión: el avance en el tratamiento de las lesiones del cartílago y del ligamento cruzado. Cuéllar explica que “en el primer caso, se abordarán las técnicas para implante de condrocitos. Éstos son células capaces de recuperar la destrucción de una zona del cartílago siempre que se trate de una lesión única, localizada. En el segundo apartado, se discutirá sobre la óptima reconstrucción del ligamento cruzado, bien con un solo paquete de fibras o reconstruyendo los dos. También se presentaran novedosos resultados de la técnica de reconstrucción del ligamento cruzado guiada por navegador”. 

Desde los quirófanos de Policlinica Gipuzkoa se retransmitirán dos cirugías en directo sobre reconstrucción de ligamentos cruzados, a cargo de los traumatólogos José Achalandabaso y Joan Carles Monllau y de reconstrucción de una lesión combinada de ligamento cruzado y menisco, por parte de los traumatólogos Eduardo Sánchez-Alepuz y Miguel Ruiz-Ibán. 

Las sesiones se complementarán con la realización de diferentes talleres dirigidos al aprendizaje de intervenciones concretas y con prácticas de técnica quirúrgica en modernos equipos de simulación.

Especialistas de todo el país exponen los avances en Artroscopia

11/03/2013 - 22:15
General
El Hospital San Juan de Dios del Aljarafe ha celebrado un curso eminentemente práctico en el que se han dado cita traumatólogos y cirujanos ortopédicos de todo el país. Durante este curso, denominado ‘Nuevas tendencias en artroscopia y rodilla’ se han realizado cuatro intervenciones de última generación relacionadas con problemas de inestabilidad de rodilla, lesiones del cartílago articular, dos de las principales causas de la artrosis de la rodilla, o el síndrome de dolor femoropatelar (SDFP) que se presenta como una de las más patologías frecuentes de esta articulación.


La artrosis de rodilla en sus fases finales puede provocar la necesidad de sustituir la articulación por una artificial (prótesis de rodilla). Varios estudios han demostrado que el tratamiento eficaz y en tiempo de estos problemas puede reducir la necesidad de reemplazo protésico de rodilla en uno de cada tres casos.
El tratamiento de estas lesiones mediante artroscopia, que es una técnica mínimamente invasiva, permite un postoperatorio menos doloroso, con menos días de hospitalización y una recuperación más rápida.
Las lesiones del cartílago articular de rodilla son fácilmente diagnosticables durante la artroscopia de rodilla, si bien las opciones de tratamiento son en ocasiones limitadas. Dado el limitado potencial regenerativo del cartílago articular, el acceso a material cuya estructura, composición, propiedades mecánicas y durabilidad sean similares al tejido original, ha incentivado el desarrollo de métodos de cultivo en laboratorio. El Servicio Andaluz de Salud ofrece en su catálogo de servicios el tratamiento mediante implante de condrocitos cultivados autólogos realizado en el Centro Regional de Transfusión Sanguínea y en el Hospital Virgen de la Victoria de Málaga.  El objetivo del curso es dar a conocer esta técnica entre los cirujanos ortopédicos andaluces, para evitar el riesgo de un tratamiento menos adecuado de los pacientes afectados por esta dolencia.
En cuanto a la reconstrucción de ligamento cruzado anterior es una intervención que se ha extendido  en los últimos diez años a la mayoría de centros hospitalarios andaluces. Desde sus inicios en los años 80 hasta la actualidad, la técnica ha evolucionado en algunos aspectos.  En este curso se ha realizado una actualización práctica de la técnica en su versión más avanzada con la oportunidad de intercambiar impresiones con los cirujanos referentes de la misma.
Por último, la denervación patelar es una técnica paliativa adecuada para el alivio sintomático del dolor de la cara anterior de la rodilla. Para que sea eficaz, es necesario que la técnica quirúrgica se adapte lo más posible a la descripción original de la misma. En este sentido el curso ha contado con la presencia del doctor Vega García autor de la misma.

A narrated overview of the use of the posterolateral portal in arthroscopic capsulolabral repair of the inferior glenoid, focusing on how this portal improves suture shuttling and anchor placement.

Article Outline

Abstract 

The Bankart lesion is considered the critical lesion in anterior shoulder instability, in which the anteroinferior glenoid labrum separates from the glenoid rim. Technical advances in arthroscopy have ushered in a shift from open to arthroscopic Bankart repair. When one is performing an arthroscopic Bankart repair, proper portal placement is critical for success in labral preparation and anchor placement. Frequently, standard anterior portals are insufficient for inferior glenoid anchor placement and suture shuttling. The posterolateral portal—located 4 cm lateral to the posterolateral corner of the acromion—simplifies and improves anchor placement, trajectory, and anatomic capsulolabral repair of the inferior glenoid. We present our preferred technique for capsulolabral repair of the inferior glenoid.
 
Anterior glenohumeral dislocation is commonly associated with a Bankart lesion, in which the anteroinferior glenoid labrum separates from the glenoid rim. Technical advances in arthroscopy have ushered in a shift from open to arthroscopic Bankart repair. Arthroscopic Bankart repair outcomes now parallel those of open Bankart repairs. When one is performing an arthroscopic Bankart repair, proper portal placement is critical for success in labral preparation and anchor placement. Moreover, recurrent instability is anterior and inferior. Therefore it is critical to anatomically reduce the anterior-band of the inferior glenohumeral ligament. Frequently, standard portals are insufficient for optimal repair, and therefore authors have used various accessory portals.1
In our experience with arthroscopic Bankart repair, the 7-o'clock posterolateral portal provides optimal access to the inferior glenoid. Labral suture passage, knot tying in the anteroinferior quadrant, and placement of suture anchors at the inferior glenoid are all improved with this approach. We present our preferred technique for arthroscopic Bankart repair, emphasizing the use of the 7-o'clock posterolateral portal. Video 1 shows a narrated review of the surgical technique.

Surgical Technique 

Patient Setup 

We prefer an interscalene block followed by general anesthesia. The patient is placed in the lateral decubitus position because we find that this provides the best possible access to and visualization of the entire capsulolabral complex. The operative extremity is examined with the patient under anesthesia to confirm the pattern of instability and to refine the operative plan, including estimating the correct amount of capsular plication. Subsequently, the patient's operative arm is prepared and draped in standard sterile fashion and suspended by gentle traction in slight abduction and forward flexion. A marking pen is used to outline the acromion, distal clavicle, and coracoid process and to mark the portal sites. The posterolateral portal is marked 4 cm off of the posterolateral acromion (Fig 1). One may trace the trajectory of the posterior clavicle laterally as confirmation of the appropriate position.

    For arthroscopic inferior labral repair with the posterolateral portal, the patient is positioned in the lateral decubitus position. We use a posterior portal (3) 2 cm inferior to the posterolateral corner of the acromion and an anterosuperior portal (1) in the rotator interval just anterior to the biceps. The posterolateral portal (2) is created by an inside-out technique with an 18-gauge spinal needle, located approximately 4 cm lateral to the posterolateral corner of the acromion (following the trajectory of the posterior border of the clavicle laterally). The arthroscope is in the anterosuperior portal for optimal visualization.

Initial Portal Placement and Diagnostic Arthroscopy 

A posterior viewing portal is created approximately 2 cm inferior to the posterolateral corner of the acromion, and a 30° arthroscope is inserted. An anterosuperior portal is then created proximal in the rotator interval, just anterior to the biceps, by use of 18-gauge spinal needle localization, and a 7-mm cannula is placed. A diagnostic arthroscopy of the glenohumeral joint is performed to identify the Bankart lesion and identify concomitant injury to other structures including the remainder of the capsulolabral complex, long head of the biceps tendon, rotator cuff, humeral head Hill-Sachs lesion, and glenoid bone stock.

Labral Preparation 

After a Bankart lesion is confirmed, the arthroscope is transferred to the anterosuperior portal for optimal viewing of the anteroinferior glenoid (Fig 2A). Proper labral preparation is critical to successful arthroscopic Bankart repair. Under arthroscopic visualization from the anterosuperior portal, a tissue liberator, from the anteroinferior working portal, is used to peel the labrum from the glenoid at the labrum-bone interface until subscapularis muscle fibers are visualized. This confirms adequate mobilization, because the capsulolabral complex often self-reduces to its native footprint after this maneuver. Next, a tissue rasp or burr is used to create punctate glenoid bleeding.

    (A) Placing the arthroscope in the anterosuperior portal provides optimal visualization of inferior capsulolabral pathology, indicated by an asterisk. (B) The posterolateral portal provides an excellent trajectory for inferior glenoid anchor placement, with drilling for anchor placement in a trajectory that is nearly perpendicular to the floor. (C) After anchor placement in the inferior glenoid through the posterolateral portal, we retain sutures in the posterolateral portal and place the cannula in the posterior portal for improved suture management during capsulolabral repair. (D) We insert the Spectrum through the posterior portal to grasp the capsule anterior to the anchor, avoiding the axillary nerve and enhancing plication of the capsular pouch. One must use a right Spectrum in a right shoulder and vice versa. (E) Sutures are tied with a sliding knot followed by alternating half-hitches, with the knot away from the articular surface.

Posterolateral Portal 

Using 18-gauge spinal needle localization, we then create a posterolateral portal percutaneously for anchor placement (Table 1). This portal is located approximately 4 cm lateral to the posterolateral corner of the acromion (following the trajectory of the posterior border of the clavicle laterally). We create this portal by an inside-out technique with an 18-gauge spinal needle. The spinal needle trajectory is nearly perpendicular to the floor, generally aimed at the coracoid, and hugging the humeral head.
Table 1. Pearls of Posterolateral Portal Placement
1. Use an inside-out technique with an 18-gauge spinal needle to localize the portal trajectory.
2. The spinal needle trajectory should be nearly perpendicular to the floor, generally aimed at the coracoid, and hugging the humeral head.
3. The incision should be approximately 4 cm lateral to the posterolateral corner of the acromion.
4. Confirm the location by following the trajectory of the posterior border of the clavicle laterally.
5. Use a percutaneous trocar for anchor drilling into the glenoid; if desired, a cannula can be used as a working portal.

Anchor Placement 

Closely following the trajectory of the spinal needle, a blunt trocar is passed through the teres minor, passing through the capsule under direct visualization, and is placed at the inferior glenoid. We prefer to gently mallet the trocar into the glenoid as we optimize the trajectory. This minimizes the risk for movement with drilling and the potential for skiving across the glenoid cartilage. The posterolateral portal enables the trocar to be placed 1 to 2 mm from the glenoid rim, minimizing drilling into the articular surface (Fig 2B). Next, the assistant drills and places the anchor (Bio-Fastak; Arthrex, Naples, FL) percutaneously through the posterolateral portal. The sutures are gently pulled to ensure capture before removal of the trocar. The sutures are retained in the posterolateral portal to facilitate suture management (Fig 2C).

Labral Repair 

After the anchor is successfully placed, we cannulate the posterior portal using a switching stick to enable suture passage and knot tying. This approach enables the Spectrum (ConMed Linvatec, Largo, FL) to grasp the anterior capsule anterior to the anchor, thus avoiding the axillary nerve and bringing the labrum back to the inferior glenoid (Fig 2D). On the basis of our experience, this angle enhances plication of the capsular pouch. A key point is that the surgeon uses the Spectrum with the opposite angle to that needed anteriorly. For example, we use a right Spectrum in a right shoulder. Moreover, one can titrate the amount of plication based on the laxity identified clinically or during the examination with the patient under anesthesia. Alternatively, once the anchor is placed, we may approach the labral repair anteriorly from the anteroinferior portal.
The sutures are shuttled by use of a simple hoop suture configuration, because this best allows the appropriate tensioning and bumper re-creation at the inferior glenoid. The suture is secured with a sliding knot, followed by alternating half-hitches (Fig 2E). The knot should be away from the articular surface. We recommend that at least 3 suture anchors be used between the 3- and 6-o'clock position for arthroscopic Bankart repair so as to achieve re-creation of the glenoid labrum and desired capsular plication. Additional anchors are placed along the anterior glenoid approximately 5 to 7 mm apart by use of the anteroinferior working portal.

Discussion 

Because of technical advances in arthroscopic instability repair, arthroscopic Bankart repair is becoming more commonly performed, with outcomes approaching those of the gold standard, open repair. Standard arthroscopic portals provide insufficient visualization and instrumentation access to the inferior glenoid. Our approach to arthroscopic Bankart repair uses the posterolateral portal, which has been previously described.2 In our experience, the advantages of the posterolateral portal are enhanced ability to place anchors in the inferior glenoid at an improved trajectory, improved anteroinferior knot tying, facilitation of anteroinferior labral repair, and anatomic reduction of the inferior glenohumeral ligament (Table 2).

In 2002 Davidson and Rivenburgh3 first described the 7-o'clock posterolateral portal in cadaveric shoulders as a way to obtain improved working access to the inferior glenoid. This portal was found to enter the glenohumeral joint through the teres minor tendon at a safe distance from the suprascapular nerve and artery (28 ± 2 mm) and from the axillary nerve and posterior circumflex humeral artery (39 ± 4 mm).3 Difelice et al.4 found in a cadaveric study that a similarly placed posterolateral portal had a distance of 34 ± 5 mm from the axillary nerve and 29 ± 3 mm from the suprascapular nerve. These studies also found that arm position did not change the distance from the portal to the neurovascular structures.34The reported uses of the posterolateral portal include arthroscopic management of humeral avulsion of the glenohumeral ligament,5 posterior instability,6 and Bankart lesions.7
