Chronic Exertional Compartment Syndrome Resolved With Running Gait Retraining: A Case Report.

A 34-year-old female athlete experienced pain, tightness, and sensation changes in her lower legs and feet when reaching approximately 1 mile (1.6 km) of her run. After a wick catheter test, an orthopaedic surgeon diagnosed her with chronic exertional compartment syndrome (CECS) and declared her eligible to undergo fasciotomy surgery. A forefoot gait is theorized to delay the symptom onset of CECS and decrease the amount of discomfort the runner experiences. The patient opted for a 6-week gait retraining program to try to alleviate her symptoms nonsurgically. The purpose of our report is to provide information about the contributing factors of CECS and to determine if gait retraining is an effective alternative to invasive surgery. After 6 weeks of gait retraining, the patient was able to run without experiencing any CECS symptoms. Also, her compartment pressures were reduced, leading the surgeon to no longer recommend fasciotomy.

Outcomes of Primary Biceps Subpectoral Tenodesis in an Active Population: A Prospective Evaluation of 101 Patients.

PURPOSE: To evaluate the surgical outcomes of a primary subpectoral biceps tenodesis for long head of the biceps tendon (LHBT) pathology in a large cohort of prospectively, serially collected, patients in a young active population that has known high physical demands and requirements of their shoulder to perform their vocation. METHODS: A retrospective review of prospectively collected data from an active military personnel with a diagnosis of a Type II SLAP tear or biceps tenosynovitis was performed. Outcomes were evaluated at a minimum follow-up time of 18 months based on preoperative and postoperative assessments of the Single Assessment Numeric Evaluation, Western Ontario Rotator Cuff index, biceps position, and return to active duty. Inclusion criteria were (1) SLAP tears on magnetic resonance arthrogram (classified into SLAP group), and (2) no SLAP tear but examination findings of biceps tendonitis (placed in the LHBT tendonitis group). Patients were excluded for full-thickness rotator cuff tears, high-grade partial thickness tears requiring repair, acromioclavicular joint pathology, and labral pathology outside of the SLAP lesion. Patients from both groups subsequently were treated with open, subpectoral tenodesis. RESULTS: Over a 6-year period at a mean follow-up of 2.75 years (range 1.5-5.7 years), 125 active-duty military personnel with mean age of 42.6 years (range 26.3-56.5) were enrolled. A total of 101 of 125 patients (81%) completed study requirements at a mean of 2.75 years (range 1.5-5.7 years). In total, 40 patients were diagnosed with type II SLAP tears (39.6%) and 61 with biceps tendonitis without SLAP tear (60.4%). Following open, subpectoral tenodesis, there was a significant improvement in patient outcomes (Western Ontario Rotator Cuff = 54% preoperative vs 89% postoperative, Single Assessment Numeric Evaluation = 58 preoperative vs 89.5 postoperative, P < .01). In total, 82% of patients returned to full activity at a mean of 4.1 months. The biceps muscle measured relative to the antecubital fossa of operative (mean 3.20 cm) versus nonoperative (3.11 cm) was not clinically different (P = .57). There was an 8% complication rate, including 3 requiring revision, 2 superficial infections, and 3 transient neurapraxias. CONCLUSIONS: Primary subpectoral open biceps tenodesis for SLAP tears or pathology of the LHBT provides significant improvement in shoulder outcomes with a reliable return to activity level with low risk for complications. LEVEL OF EVIDENCE: Level IV (Case series).

Hip Arthroscopy for Femoroacetabular Impingement in a Military Population.

BACKGROUND: Femoroacetabular impingement (FAI) can lead to hip pain and early joint degeneration. There have been few reports to date on the outcomes of hip arthroscopy for the treatment of FAI in the military population. Purpose/Hypothesis: The purpose of this study was to compare patient demographics with postoperative outcomes after hip arthroscopy for symptomatic FAI and to identify preoperative risk factors for poor outcomes. The hypothesis was that certain preoperative patient characteristics will be predictive of poorer outcomes and that lower outcomes scores will be associated with a higher likelihood of medical separation from the military. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Retrospective chart review of active-duty and dependent patients older than 18 years who underwent hip arthroscopy for symptomatic FAI from 2009 to 2014 at a single institution. RESULTS: A total of 469 (309 males and 160 females) surgeries were performed on 456 active-duty personnel and 13 dependent civilians, with a mean 2.5-year follow-up. Overall, 39% (n = 179) were able to return to duty (RTD), 18% (n = 82) were medically cleared to return to normal daily activities but did not remain on active duty, and 43% (n = 195) required referral to the Disability Evaluation System (DES). Increasing rank and male sex were positive predictors and Axis 1 psychiatric diagnosis, revision surgery, concomitant psoas tenotomy, multiple medical comorbidities, and complaints of generalized pelvic pain were negative predictors for returning to duty. US Marine Infantry and Special Forces showed improved RTD rates (50%-86%) compared with administrative, more sedentary, occupations (22%). On average, Single Alpha Numeric Evaluation (SANE) and visual analog scale (VAS) scores improved after surgery, with SANE scores improving 37 ± 28 points and VAS scores improving 2.6 ± 2.5 points. The mean postoperative SANE and VAS scores differed significantly between the RTD group and those not returning to duty; 87 and 1.2 points compared with 69 and 3.6 points, respectively ( P < .0001). CONCLUSION: Hip arthroscopy for the treatment of symptomatic FAI effectively improves pain symptoms and self-reported overall function but shows a much lower than expected return to full, unrestricted active duty in the general active-duty military population. Underlying psychiatric diagnoses, female sex, and more sedentary occupations are associated with lower RTD rates. Furthermore, lower postoperative SANE and VAS scores are associated with lower RTD rates. Only the more active and elite components of the military study population showed RTD rates consistent with previously reported outcomes of return to competitive sports after hip arthroscopy for FAI.

Prospective Evaluation of Surgical Treatment of Humeral Avulsions of the Glenohumeral Ligament.

BACKGROUND: Humeral avulsion of the glenohumeral ligament (HAGL) is an infrequent but significant contributor to shoulder dysfunction, instability, and functional loss. PURPOSE: To prospectively identify patients with HAGL lesions and then conduct retrospective evaluation of the clinical history, examination findings, and surgical outcomes of these patients. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Over a 6-year period (2006-2011), patients with shoulder dysfunction and a HAGL lesion that was confirmed via magnetic resonance arthrogram (MRA) were prospectively evaluated with a minimum 2-year follow-up. Patient demographics, presentation, examination, and surgical findings were documented. Outcomes of return to activity as well as Western Ontario Shoulder Instability Index (WOSI) and Single Assessment Numeric Evaluation (SANE) scores were recorded at final follow-up. Anterior HAGL (aHAGL) lesions were repaired with a partial subscapularis tenotomy approach, while reverse (rHAGL) lesions were repaired arthroscopically. RESULTS: Of 28 patients, 27 (96%) completed the study requirements at a mean of 36.2 months (range, 24-68 months). The sample contained 12 females (44%) and 15 males (56%), who had a mean age of 24.9 years (range, 18-34 years). The chief complaint reported was pain in 23 patients (85%), while only 4 (15%) patients complained primarily of recurrent instability symptoms. Fourteen patients (52%) had aHAGL lesions, 10 patients (37%) had rHAGL lesions, and 3 patients (11%) had combined aHAGL and rHAGL lesions. Ten patients (37%) had concomitant HAGL lesions and labral tears, whereas 17 patients (63%) had isolated HAGL lesion without labral tear. The 17 patients (63%) with aHAGL lesions or combined lesions underwent a partial subscapularis tenotomy approach, while the remaining 10 patients (37%) with rHAGL lesions underwent arthroscopic surgical repair. After surgery, WOSI outcomes improved from 54% to 88% and SANE outcomes improved from 50% to 91% ( P < .01 for both), with no reports in recurrence of instability symptoms at final follow-up. CONCLUSION: This study demonstrated that patients with symptomatic HAGL lesions predominantly report shoulder pain and dysfunction, with few chief complaints of recurrent instability complaints. After surgery, patients showed predictable return to full activity, improvement in objective and patient-reported outcomes, and satisfaction with treatment outcome.

The efficacy of biceps tenodesis in the treatment of failed superior labral anterior posterior repairs.

BACKGROUND: The incidence and arthroscopic treatment of superior labral anterior posterior (SLAP) tears have increased over the past decade. Recent evidence has identified factors associated with poor outcomes, including age, overhead activity, and concomitant rotator cuff tears. Biceps tenodesis has also been suggested as an alternative treatment to repair. Moreover, there are no studies demonstrating effective treatment strategies for failed type II SLAP repairs. PURPOSE: To prospectively evaluate the surgical outcomes of biceps tenodesis for patients who undergo elected revision surgery after an arthroscopically repaired type II SLAP tear. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: After institutional review board approval, 46 patients who met failure criteria for an arthroscopically repaired type II SLAP tear elected to undergo open subpectoral tenodesis by 2 fellowship-trained surgeons from 2006 to 2010 at a tertiary care military treatment facility. Objective outcomes were preoperative and postoperative assessments with the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and Western Ontario Shoulder Instability Index (WOSI) scores and an independent physical examination. Statistical analysis was performed via analysis of variance. RESULTS: Of the 46 patients, 42 completed the study (91% follow-up rate). The mean age of the patients was 39.2 years, 85% were male, and the mean follow-up period was 3.5 years (range, 2.0-6.0 years). The rate of return to active duty and sports was 81%. There was a clinically and statistically significant improvement across all outcome assessments after revision surgery (preoperative mean scores: ASES = 68, SANE = 64, WOSI = 65; postoperative mean scores: ASES = 89, SANE = 84, WOSI = 81) (P < .0001) and shoulder range of motion (preoperative mean values: forward flexion = 135°, abduction = 125°; postoperative mean values: forward flexion = 155°, abduction = 155°) (P < .0001). There was 1 case of transient musculocutaneous nerve neurapraxia. CONCLUSION: Biceps tenodesis is a predictable, safe, and effective treatment for failed arthroscopic SLAP tears at a minimum 2-year follow-up. The majority of patients obtained good to excellent outcomes using validated measures with a significant improvement in range of motion.

Disorders of the proximal and distal aspects of the biceps muscle.

PROXIMAL ASPECT OF BICEPS: Tenodesis of the long head of the biceps may offer improved cosmesis, improved strength, and diminished activity-related pain compared with tenotomy, although comparative studies have shown similar outcomes in some patient populations. DISTAL ASPECT OF BICEPS: Operative treatment of both partial and complete distal biceps ruptures results in better outcomes compared with nonoperative care, although the optimal technique and fixation are yet to be determined. Nonoperative management is an acceptable treatment for patients willing to accept some loss of forearm supination and elbow flexion strength as well as changes in endurance and cosmesis.

A prospective analysis of 179 type 2 superior labrum anterior and posterior repairs: outcomes and factors associated with success and failure.

BACKGROUND: There is a paucity of type 2 superior labrum anterior and posterior (SLAP) surgical outcomes with prospective data. PURPOSE: To prospectively analyze the clinical outcomes of the arthroscopic treatment of type 2 SLAP tears in a young, active patient population, and to determine factors associated with treatment success and failure. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Over a 4-year period, 225 patients with a type 2 SLAP tear were prospectively enrolled. Two sports/shoulder-fellowship-trained orthopaedic surgeons performed repairs with suture anchors and a vertical suture construct. Patients were excluded if they underwent any additional repairs, including rotator cuff repair, labrum repair outside of the SLAP region, biceps tenodesis or tenotomy, or distal clavicle excision. Dependent variables were preoperative and postoperative assessments with the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and Western Ontario Shoulder Instability (WOSI) scores and independent physical examinations. A failure analysis was conducted to determine factors associated with failure: age, mechanism of injury, preoperative outcome scores, and smoking. Failure was defined as revision surgery, mean ASES score below 70, or an inability to return to sports and work duties, which was assessed statistically with the Student t test and stepwise logarithmic regression. RESULTS: There were 179 of 225 patients who completed the follow-up for the study (80%) at a mean of 40.4 months (range, 26-62 months). The mean preoperative scores (WOSI, 54%; SANE, 50%; ASES, 65) improved postoperatively (WOSI, 82%; SANE, 85%; ASES, 88) (P < .01). The mean postoperative range of motion was 159° of flexion, 151° of abduction, and 51° of external rotation at the side, which was less than the mean preoperative range of motion (164° of flexion, 166° of abduction, and 56° of external rotation at the side). Of the 179 patients, 66 patients (36.8%) met failure criteria. Fifty patients elected revision surgery. Advanced age within the cohort (>36 years) was the only factor associated with a statistically significant increase in the incidence of failure. Those who were deemed failed had a mean age of 39.2 years (range, 29-45 years) versus those who were deemed healed with a mean age of 29.7 years (range, 18-36 years) (P < .001). The relative risk for failure for patients older than 36 years was 3.45 (95% CI, 2.0-4.9). CONCLUSION: Arthroscopic SLAP repair provides a clinical and statistically significant improvement in shoulder outcomes. However, a reliable return to the previous activity level is limited; 37% of patients had failure, with a 28% revision rate. Age greater than 36 years was associated with a higher chance of failure. Additional work is necessary to determine the optimal diagnosis, indications, and surgical management for those with SLAP injuries.

An analysis of shoulder outcomes scores in 275 consecutive patients: disease-specific correlation across multiple shoulder conditions.

OBJECTIVES: To determine the outcomes scores of military patients who initially present with a variety of shoulder conditions, identify which scores demonstrate the highest correlation per diagnosis, and determine if a difference exists for patients who went onto surgery. METHODS: Two-hundred and seventy five consecutive patients with mean age of 36.5 +/- 12.9 at presentation completed baseline outcomes assessments that included Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons (ASES) Score, Western Ontario Shoulder Instability Index (WOSI), Western Ontario Rotator Cuff Index (WORC), the Simple Shoulder Test (SST), and the Disabilities of the Arm, Shoulder, and Hand Index (DASH). The patients were grouped by clinical, radiographic, and surgical findings into 10 diagnostic categories. OUTCOMES: The initial mean outcomes scores were SANE 48.8, ASES 50.1, WOSI 1279 (40% normal), WORC 1122.4 (47% normal), SST 6.7, and DASH 33.1. Patients with superior labrum anterior-posterior tears demonstrated the lowest mean scores, followed by instability and rotator cuff tear patients. For all conditions, scores were lower for patients who went onto surgery compared with those managed nonoperatively (p = 0.008). CONCLUSIONS: Our findings may be utilized as a baseline to compare and track patient-derived disability across multiple shoulder conditions and serve to define mean diagnosis-specific shoulder patient preoperative scores.

Decreased femoral head-neck offset: a possible risk factor for ACL injury.

PURPOSE: Reduction in anterior cruciate ligament (ACL) injuries in young, active individuals continues to be a major goal in sports medicine. The purpose of this study was to determine the head-neck offset, as measured by AP pelvis alpha angles, in patients presenting to a single surgeon with isolated ACL and non-ACL knee injuries. METHODS: In a group of 48 patients with complete, primary ACL rupture and 42 controls with non-ACL injury (i.e., meniscus tear, cartilage defect), a single surgeon, blinded to the diagnosis, took radiographic measures of the AP alpha angle of both hips and the weight-bearing line at both knees. All knee pathology was confirmed with knee arthroscopy. Inclusion criteria included no previous hip or knee surgery, and long-leg standing alignment radiographic series completed at index visit. RESULTS: There was no difference in gender distribution, height, BMI or age between groups. ACL-injured patients had a significantly higher alpha angle (mean = 84, SD = 14) on the injured side than the controls (mean = 59, SD = 7, p < 0.0001). Ninety-four percent of the ACL-injured group had alpha angles over 60°, while only 35% of the non-ACL-injured group had alpha angles over 60° (p = 0.001). Those patients with alpha angle over 60° were 27 times more likely (95% CI 6.4-131) to be in the ACL injury group than those patients with alpha angle 60° or less (p = 0.001). CONCLUSION: Our findings establish an important preliminary correlation between ACL injury and diminished femoral head-neck offset, as characterized by abnormal, elevated alpha angles. LEVEL OF EVIDENCE: Prognostic study, Level III.

Pectoralis major muscle rupture repair: technique using unicortical buttons.

Over the past few decades, there has been increased awareness of pectoralis major muscle injuries necessitating further evaluation of management options and, in particular, surgical repair. Injury typically occurs when an eccentric load is applied to the muscle, such as with bench pressing, and failure usually occurs through the tendon. Although nonoperative management is sometimes appropriate, given the injury's propensity for young, active male patients, surgical intervention is often warranted. Because the injury typically occurs at the muscle-tendon interface, surgery focuses on repair of the avulsed tendon into its anatomic attachment site. We describe the use of a unicortical suture button to repair the ruptured tendon. This technique achieves the goals of strong fixation and anatomic repair of the tendon back into its native footprint.

Two-year outcomes of open shoulder anterior capsular reconstruction for instability from severe capsular deficiency.

PURPOSE: To document outcomes after anterior capsulolabral reconstruction for recurrent shoulder instability in 15 patients (20 shoulders) who have had multiple failed stabilizations or collagen disorders. METHODS: Twenty shoulders with recurrent instability underwent revision stabilization with allograft reconstruction of anterior capsulolabral structures, which re-creates the labrum and capsular ligaments. The patients comprised 3 men and 12 women (mean age, 26 years [range, 18 to 38 years]) in whom multiple prior repairs failed and who had disability from continued pain and instability. Patients could choose to undergo either arthrodesis or salvage allograft reconstruction or to live with permanent disability. Of the patients, 5 had Ehlers-Danlos syndrome whereas 10 had hyperlaxity syndromes without genetic confirmation. Failure was defined as further instability surgery. Pain, shoulder function, instability (dislocations/subluxation), and American Shoulder and Elbow Surgeons scores were documented. RESULTS: At follow-up, 9 of 20 shoulders (45%) remained stable. Recurrent instability was reported in 5 shoulders (25%), but the patients chose not to undergo further surgery. In the 14 shoulders without further stabilization (nonfailures), the mean American Shoulder and Elbow Surgeons score increased 43 points at a mean of 3.8 years (range, 2 to 6 years) postoperatively (P < .05). Mean satisfaction with outcome in nonfailures was 7 of 10 points (range, 1 to 10). Six shoulders failed by progressing to instability surgery at a mean of 8.6 months (range, 2.8 to 24 months). In the 6 shoulders that failed, the mean number of prior surgeries was 8 (range, 3 to 15) compared with a mean of 4 prior surgeries (range, 1 to 16) for the 9 nonfailures. CONCLUSIONS: Treating patients in whom multiple stabilizations have failed remains challenging. In our series 9 shoulders (45%) remained completely stable at 3.8 years. Recurrent instability (3 reinjuries) requiring further stabilization occurred in 6 (30%). Subsequent treatment for non-instability reasons was performed in 3 (15%). Instability was reported but revision surgery was not performed in 5 (25%). In 8 nonfailures (64%), the patients were highly satisfied with their surgical outcomes. Our results support this salvage procedure as a viable alternative to arthrodesis in young patients with end-stage shoulder instability or collagen disorders. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Technique: bone-patellar tendon-bone autograft ACL reconstruction in the young, active patient.

Successful treatment of the anterior cruciate ligament tear in the young, active population can be reliably achieved with an arthroscopic bone-patellar tendon-bone (BTB) autograft reconstruction. Although some contraindications exist, the BTB autograft has been proven to provide for a durable, stable, and highly functional knee. Complications associated with the use of BTB can occur, but measures can be taken to minimize these risks. In addition to appropriate graft selection, meticulous surgical technique is required. This article outlines the step-by-step surgical technique including graft harvest, tunnel placement, graft preparation and passage, and interference screw fixation. Potential complications and the surgical decision-making options incurred are also discussed in detail.

Anatomy, function, injuries, and treatment of the long head of the biceps brachii tendon.

Lesions of the long head biceps tendon (LHB) are frequent causes of shoulder pain and disability. Biceps tenotomy and tenodesis have gained widespread acceptance as effective procedures to manage both isolated LHB pathology and combined lesions of the rotator cuff and biceps-labral complex. The function of the LHB tendon and its role in glenohumeral kinematics presently remain only partially understood because of the difficulty of cadaveric and in vivo biomechanical studies. The purpose of this article is to offer an up-to-date review of the anatomy and biomechanical properties of the LHB and to provide an evidence-based approach to current treatment strategies for LHB disorders.

Arthroscopic repair of circumferential lesions of the glenoid labrum: surgical technique.

BACKGROUND: Symptomatic pan-labral or circumferential (360°) tears of the glenohumeral labrum are an uncommon injury. The purpose of the present study was to report the results of surgical treatment of circumferential lesions of the glenoid labrum with use of validated outcome instruments. METHODS: From July 2003 to May 2006, forty-one shoulders in thirty-nine patients (thirty-four men and five women) with a mean age of 25.1 years were prospectively enrolled in a multicenter study and were managed for a circumferential (360°) lesion of the glenoid labrum. All patients had a primary diagnosis of pain and recurrent shoulder instability, and all underwent arthroscopic repair of the circumferential labral tear with a mean of 7.1 suture anchors. The outcomes for thirty-nine of the forty-one shoulders were assessed after a mean duration of follow-up of 31.8 months on the basis of the rating of pain and instability on a scale of 0 to 10, a physical examination, and three outcome instruments (the Single Assessment Numeric Evaluation score, the modified American Shoulder and Elbow Surgeons score, and the Short Form-12 score). RESULTS: Significant improvement was noted in terms of the mean pain score (from 4.3 to 1.1), the mean instability score (from 7.3 to 0.2), the mean modified American Shoulder and Elbow Surgeons score (from 55.5 to 89.6), the mean Short Form-12 score (from 75.7 to 90.0), and the mean Single Assessment Numeric Evaluation score (from 36.7 to 88.5). Six shoulders required revision surgery because of recurrent instability (two), recalcitrant biceps tendinitis (two), or postoperative tightness (two). All patients returned to their preinjury activity level. CONCLUSIONS: Pan-labral or circumferential lesions are an uncommon yet extensive injury of the glenohumeral joint that may result in recurrent instability and pain. The present study demonstrates that arthroscopic capsulolabral repair with suture anchor fixation can restore the stability of the glenohumeral joint and can provide a reliable improvement in subjective and objective outcome measures.

Arthroscopic labral reconstruction in the hip using iliotibial band autograft: technique and early outcomes.

PURPOSE: The purpose of this study was to investigate the indications for and outcomes of arthroscopic labral reconstruction in the hip by use of iliotibial band (ITB) autograft. METHODS: Between August 2005 and May 2008, the senior author (M.J.P.) performed 95 arthroscopic labral reconstructions using an ITB autograft in patients with advanced labral degeneration or deficiency. There were 47 patients who had undergone surgery at a minimum of 1 year previously and met the inclusion criteria. The modified Harris Hip Score (MHHS) and patient satisfaction were used to measure outcomes postoperatively. The labral autograft was harvested from the ITB through a separate incision. The graft was sutured to the intact labral remnant in the region of labral deficiency, re-establishing the suction seal of the hip joint. RESULTS: There were 32 men and 15 women. The mean age at the time of surgery was 37 years (range, 18 to 55 years). The mean time from the onset of symptoms to labral reconstruction was 36 months (range, 1 month to 12 years). Subsequent total hip arthroplasty was performed in 4 patients (9%). Follow-up was obtained in 37 of the remaining 43 patients. The mean time to follow-up was 18 months (range, 12 to 32 months). The mean MHHS improved from 62 (range, 35 to 92) preoperatively to 85 (range, 53 to 100) postoperatively (P = .001). Median patient satisfaction was 8 out of 10 (range, 1 to 10). Patients who were treated within 1 year of injury had higher MHHSs than patients who waited longer than 1 year (93 v 81, P = .03). The independent predictor of patient satisfaction with outcome after labral reconstruction was age. CONCLUSIONS: This study showed that patients who have labral deficiency or advanced labral degeneration had good outcomes and high patient satisfaction after arthroscopic intervention with acetabular labral reconstruction. Lower satisfaction was associated with joint space narrowing and increased age. Patients who waited longer than 1 year from the time of injury to surgery had lower function at follow-up than those treated in the first year. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Glenohumeral joint preservation: current options for managing articular cartilage lesions in young, active patients.

This is a review of joint-preservation techniques for the shoulder. Whereas the management of diffuse articular cartilage loss in the glenohumeral joints of elderly and less active patients by total shoulder arthroplasty is well accepted, significant controversy persists in selecting and refining successful operative techniques to repair symptomatic glenohumeral cartilage lesions in the shoulders of young, active patients. The principal causes of focal and diffuse articular cartilage damage in the glenohumeral joint, including previous surgery, trauma, acute or recurrent dislocation, osteonecrosis, infection, chondrolysis, osteochondritis dissecans, inflammatory arthritides, rotator cuff arthropathy, and osteoarthritis, are discussed. Focal cartilage lesions of the glenohumeral joint are often difficult to diagnose and require a refined and focused physical examination as well as carefully selected imaging studies. This review offers a concise guide to surgical decision making and up-to-date summaries of the current techniques available to treat both focal chondral defects and more massive structural osteochondral defects. These techniques include microfracture, osteoarticular transplantation (OATS [Osteochondral Autograft Transfer System]; Arthrex, Naples, FL), autologous chondrocyte implantation, bulk allograft reconstruction, and biologic resurfacing. As new approaches to glenohumeral cartilage repair and shoulder joint preservation evolve, there continues to be a heightened need for collaborative research and well-designed outcomes analysis to facilitate successful patient care.

Arthroscopic repair of circumferential lesions of the glenoid labrum.

BACKGROUND: Symptomatic pan-labral or circumferential (360 degrees ) tears of the glenohumeral labrum are an uncommon injury. The purpose of the present study was to report the results of surgical treatment of circumferential lesions of the glenoid labrum with use of validated outcome instruments. METHODS: From July 2003 to May 2006, forty-one shoulders in thirty-nine patients (thirty-four men and five women) with a mean age of 25.1 years were prospectively enrolled in a multicenter study and were managed for a circumferential (360 degrees ) lesion of the glenoid labrum. All patients had a primary diagnosis of pain and recurrent shoulder instability, and all underwent arthroscopic repair of the circumferential labral tear with a mean of 7.1 suture anchors. The outcomes for thirty-nine of the forty-one shoulders were assessed after a mean duration of follow-up of 31.8 months on the basis of the rating of pain and instability on a scale of 0 to 10, a physical examination, and three outcome instruments (the Single Assessment Numeric Evaluation score, the modified American Shoulder and Elbow Surgeons score, and the Short Form-12 score). RESULTS: Significant improvement was noted in terms of the mean pain score (from 4.3 to 1.1), the mean instability score (from 7.3 to 0.2), the mean modified American Shoulder and Elbow Surgeons score (from 55.5 to 89.6), the mean Short Form-12 score (from 75.7 to 90.0), and the mean Single Assessment Numeric Evaluation score (from 36.7 to 88.5). Six shoulders required revision surgery because of recurrent instability (two), recalcitrant biceps tendinitis (two), or postoperative tightness (two). All patients returned to their preinjury activity level. CONCLUSIONS: Pan-labral or circumferential lesions are an uncommon yet extensive injury of the glenohumeral joint that may result in recurrent instability and pain. The present study demonstrates that arthroscopic capsulolabral repair with suture anchor fixation can restore the stability of the glenohumeral joint and can provide a reliable improvement in subjective and objective outcome measures.

Treatment of osseous defects associated with anterior shoulder instability.

Bone loss of the glenoid and/or humerus is a common consequence of traumatic anterior shoulder instability and can be a cause of recurrent instability after a Bankart repair. Accurate characterization of the size and location of osseous defects associated with traumatic instability is important when planning treatment. Open or arthroscopic soft tissue repairs are usually sufficient when less than 25% of the width of the glenoid bone has been lost. Bone replacement techniques may be necessary when glenoid bone loss is greater than 25% of the glenoid width. Glenoid bone restoration techniques include the use of a tricortical iliac crest graft or the transfer of the coracoid process to the area of glenoid deficiency. Bone grafting becomes a strong consideration when soft tissue repairs have failed to restore stability. Treatment of these severe defects may be followed by osteoarthritis. The destabilizing effects of anterior glenoid bone defects are compounded by concurrent defects of the posterior-lateral humeral head, commonly known as Hill-Sachs lesions, which can engage the glenoid defect. Large humeral head defects can be treated by transhumeral bone grafting techniques or osteoarticular allograft reconstruction. Prosthetic replacement of the proximal humerus is considered for humeral head defects involving more than 40% of the articular surface. Understanding the importance of humeral and glenoid bone deficiencies may help guide the treatment of recurrent anterior glenohumeral instability.
