Injury to the superior glenoid labrum is increasingly recognized as a significant source of shoulder pain and dysfunction in the throwing athlete. Several theories have been proposed to explain the pathogenesis of superior labral anterior posterior (SLAP) tears. The clinical examination of the superior labrum-biceps tendon complex remains challenging because of a high association of other shoulder injuries in overhead athletes. Many physical examination findings have high sensitivity and low specificity. Advances in soft tissue imaging such as magnetic resonance arthrography allow for improved detection of labrum and biceps tendon lesions, although correlation with history and physical examination is critical to identify symptomatic lesions. Proper treatment of throwers with SLAP tears requires a thorough understanding of the altered biomechanics and the indications for nonoperative management and arthroscopic treatment of these lesions.

Purpose Compared to a relatively older population over 30-40 years of age, the eicacy of biceps tenodesis for type II SLAP lesions in a younger population is not well studied. The purpose of this study was to compare outcomes between biceps tenodesis and labral repair for type II SLAP lesions in a young active population. Methods Patients aged 15-40 who underwent primary arthroscopic biceps tenodesis or SLAP repair for type II SLAP tears between 2009 and 2016 were included. Shoulders with intraarticular chondral damage, full thickness rotator cuf tear, rotator cuf repair, labral repair outside of the superior labrum, bony subacromial decompression, and acromioclavicular joint resection were excluded. Patient-reported outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand Sports/Performing Arts Module (DASH-sport), visual analog scale (VAS) for pain, and satisfaction. Return to sport rates were also recorded. Results Fifty-three patients (20 tenodesis, 33 repair) were available for minimum 2-year follow-up. Postoperatively, there were no signiicant diferences in mean ASES, DASH-sport, VAS, and satisfaction between groups [ASES: tenodesis 86.3 vs. repair 86.4 (n.s.); DASH-sport: 11.0 vs. 22.5 (n.s.); VAS: 1.85 vs. 1.64 (n.s.); satisfaction: 8.50 vs. 8.00 (n.s.)]. Rate of return to pre-injury level of performance/competition in sport/physical activity was also similar between groups [tenodesis 63% vs. repair 50% (n.s.)]. Conclusions In a young active population, primary arthroscopic biceps tenodesis is a viable surgical alternative to labral repair for type II SLAP lesions. The results of this study suggest that indications for arthroscopic tenodesis can safely be expanded to a younger patient group than has previously been demonstrated in the literature.

Lateral epicondylitis is a common source of elbow pain. Though it is often a self-limited condition, refractory lateral epicondylitis can lead to problems with activities of daily living and sometimes requires sick leave from work. Therefore prompt treatment is essential. Histopathologic studies have suggested that lateral epicondylitis is a tendinopathy, associated with apoptosis and autophagy, rather than a tendonitis associated with inflammation. Although corticosteroids have been used for short-term treatment, recent studies have suggested that they are not helpful and may even be harmful and delay healing in the treatment of lateral epicondylitis. Researchers have recently begun to investigate the use of biologics as potential treatment options for lateral epicondylitis. Autologous blood preparations including platelet rich plasma (PRP) and autologous whole blood injections (ABIs) have been proposed in order to deliver growth factors and other nutrients to the diseased tendon. Stem cell therapies have also been suggested as a method of improving tendon healing. This review discusses the current evidence for the use of PRP, ABI, and stem cell therapies for treatment of lateral epicondylitis. We also review the evidence for nonbiologic treatments including corticosteroids, prolotherapy, botulinum toxin A, and nitric oxide.

Background:Previous authors have suggested that intra-articular morphine and clonidine injections after knee arthroscopy have demonstrated equivocal analgesic effect in comparison with bupivacaine while circumventing the issue of chondrotoxicity. There have been no studies evaluating the effect of intra-articular morphine after hip arthroscopy.Purpose:To evaluate the efficacy of intra-articular morphine in combination with clonidine on postoperative pain and narcotic consumption after hip arthroscopy surgery for femoroacetabular impingement.Study Design:Cohort study; Level of evidence, 3.Methods:A retrospective chart review was performed on 43 patients that underwent hip arthroscopy for femoroacetabular impingement at a single institution between September 2014 and May 2015. All patients received preoperative celecoxib and acetaminophen, and 22 patients received an additional intra-articular injection of 10 mg morphine and 100 μg of clonidine at the conclusion of the procedure. Narcotic consumption, duration of anesthesia recovery, and perioperative pain scores were compared between the 2 groups.Results:Patients who received intra-articular morphine and clonidine used significantly less opioid analgesic (mEq) in the postanesthesia recovery (median difference, 17 mEq [95% CI, –32 to –2 mEq]; P = .02) compared with the control group. There were no differences in time spent in recovery before hospital discharge or in visual analog pain scores recorded immediately postoperatively and at 1 hour after surgery.Conclusion:Intraoperative intra-articular injection of morphine and clonidine significantly reduced the narcotic requirement during the postsurgical recovery period after hip arthroscopy. The reduction in postsurgical opioids may decrease adverse effects, improve overall pain management, and lead to better quality of recovery and improved patient satisfaction.

Background:The presence of multiple allergies has been correlated with worse outcomes for patients undergoing hip and knee arthroplasty, but the effect of allergies has not yet been elucidated with respect to shoulder arthroplasty.Purpose/Hypothesis:The purpose of this study is to identify any discrepancies in shoulder arthroplasty outcomes with respect to reported drug allergies. We hypothesized that patients with multiple drug allergies would have inferior outcomes.Study Design:Cohort study; Level of evidence, 3.Methods:Included in the analysis were a single surgeon’s cases between 2009 and 2014 of primary total shoulder arthroplasty with a minimum of 180 days of follow-up. Cases with fracture as the indication were excluded. Preoperative and postoperative metrics included visual analog scale (VAS) for pain, forward flexion range of motion, and Simple Shoulder Test (SST) results, and postoperative patient satisfaction scores were also collected. Chi-square and 1-way analysis of variance with Tukey post hoc analyses were performed when appropriate.Results:A total of 98 patients were included (no allergies, n = 51; single allergy, n = 21; multiple allergies, n = 26). The proportion of females was greater with increasing number of allergies (no allergies, 31%; single allergies, 47%; multiple allergies, 88%; Pearson χ2 = 22.5; P < .0001). Both preoperatively and postoperatively, no difference was found between cohorts with respect to SST score, VAS score, or forward flexion. There was also no difference in postoperative satisfaction between cohorts. No difference between cohorts was identified when comparing the pre- to postoperative change in SST scores, VAS scores, or forward flexion.Conclusion:The presence of single or multiple allergies is not correlated with worse outcomes after primary anatomic total shoulder arthroplasty.
