Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point. Hip arthroscopic surgery for the management of symptomatic labral tears in patients with combined overcoverage and coxa profunda is associated with improvements in patient outcomes and pain at a minimum 2-year follow-up. However, the degree of improvement is of lower magnitude compared with a matched cohort with normal coverage undergoing the arthroscopic management of symptomatic labral tears. While hips with lateral overcoverage combined with coxa profunda may have a smaller potential for improvement compared with hips with normal coverage, this type of osseous morphology is still repairable with arthroscopic treatment.   Click here to read the article.

Radial meniscus tears disrupt the circumferential fibers and thereby compromise meniscus integrity. Historically, radial tears were often treated with meniscectomy because of an incomplete understanding of the biomechanical consequences of these tears, limited information regarding the biomechanical performance of repair, and the technical difficulty associated with repair. There is a paucity of studies on the outcomes of the repair of radial meniscus tears. The purpose was to determine the outcomes of 2-tunnel transtibial repair of radial meniscus tears and compare these results to the outcomes of patients who underwent the repair of vertical meniscus tears with a minimum of 2-year follow-up. The hypothesis was that radial and vertical meniscus tear repair outcomes were comparable. The 2-tunnel transtibial pullout technique for the repair of radial meniscus tears produces similar clinical outcomes when compared with the repair of vertical meniscus tears at a mean 3.5 years’ follow-up.   Click here to read th

Anterior cruciate ligament (ACL) injuries occur commonly in football. Recent work has reported ACL reconstruction (ACLR) as one of several orthopaedic procedures with unfavorable outcomes for professional athletes. The performance impact to defensive players after surgery has not been quantified. Approximately 74% (28/38) of athletes who underwent ACLR returned to play at least 1 NFL game, and 61% (23/38) successfully returned to play at least half a season (ie, 8 games). Players who successfully returned were above-average NFL players before their injury but comparatively average after their return.   Click here to read the article.

Graft failure and low rates of return to sport are major concerns after anterior cruciate ligament (ACL) reconstruction, particularly in a population at risk. The purpose of this study was to evaluate the association between reconstruction techniques and subsequent graft rupture and return-to-sport rates in patients aged 16 to 30 years participating in pivoting sports. In conclusion, in a high-risk population of young patients participating in pivoting sports, the rate of graft failure with HT+ALL grafts was 2.5 times less than with B-PT-B grafts and 3.1 times less than with 4HT grafts. The HT+ALL graft is also associated with greater odds of returning to preinjury levels of sport when compared with the 4HT graft.   Click here to read the article.

The use of allograft tissue for anterior cruciate ligament reconstruction (ACLR) remains controversial. The purpose of this study is to compare the risk of aseptic revision between bone–patellar tendon–bone (BPTB) autografts and BPTB allografts. In conclusion, when BPTB allograft tissue was used for ACLR, an overall 4.54 times adjusted higher risk of revision was observed compared with surgery performed with a BPTB autograft. Whether the tissue was irradiated with either high- or low-dose radiation, chemically processed, or not processed at all made little difference in the risk of revision. The differences in the revision risk were also consistent in younger and older patients. Surgeons and patients should be aware of the increased risk of revision when a BPTB allograft is used for ACLR.   Click here to read the article.

Quantitative magnetic resonance (qMR) can be used to measure macromolecules in tissues and is a potential method of observing early cartilage changes in the development of posttraumatic osteoarthritis. We hypothesized that specific patient and surgical factors affecting cartilage matrix composition after anterior cruciate ligament (ACL) reconstruction (ACLR) can be detected using T1ρ and T2 relaxation times. Our purpose was to demonstrate this ability in a multicenter feasibility study. We concluded that prolonged relaxation times in multiple regions demonstrate how the injury affects the entire joint after an ACL tear. Changes observed in the uninjured knee may be caused by increased loading during rehabilitation, especially in the patellofemoral articular cartilage and distal femur. Relaxation times in the tibial regions may be predictive of patient symptoms at 6 months. These same regions are affected by surgical timing as early as 30 days after injury, but this may partially be reflective of the severity

Patient selection is critical when choosing between arthroscopic joint preservation and total shoulder arthroplasty in young patients with glenohumeral osteoarthritis (GHOA). The purpose of this study was to identify prognostic factors predictive of early failure in patients undergoing comprehensive arthroscopic management (CAM) for GHOA. The CAM procedure has been shown to reliably improve pain and function in active patients with advanced GHOA; however, it is important to inform patients about the limitations of the procedure. Patients with less joint space and abnormal posterior glenoid shape were significantly more likely to progress to early failure.   Click here to read the article.

The use of platelet-rich plasma (PRP) for the treatment of osteoarthritis (OA) has demonstrated mixed clinical outcomes in randomized controlled trials when compared with hyaluronic acid(HA), an accepted nonsurgical treatment for symptomatic OA. Biological analysis of PRP has demonstrated an anti-inflammatory effect on the intra-articular environment. We found no difference between HA and PRP at any time point in the primary outcome measure: the patient-reported WOMAC pain score. Significant improvements were seen in other patient-reported outcome measures, with results favoring PRP over HA. Preceding a significant difference in subjective outcomes favoring PRP, there was a trend toward a decrease in 2 proinflammatory cytokines, which suggest that the anti-inflammatory properties of PRP may contribute to an improvement of symptoms.   Click here to read the article.

Pectoralis minor (PM) tightness has been linked to pain and dysfunction of the shoulder joint secondary to anterior tilt and internal rotation of the scapula, thus causing secondary impingement of the subacromial space. In most patients, PM tightness can be successfully treated with a nonoperative focused PM stretching program. However, in refractory and pathologically tight PM cases, this series demonstrates predictable return to function with notable improvement in shoulder symptoms after surgical release of the PM. Additional research is necessary to evaluate the long-term efficacy of isolated PM treatment.   Click here to read the article.

Shoulder pain is a common problem in competitive swimmers, but the structural alterations in elite-level competitive swimmers are not well known. We found a high prevalence of rotator cuff and biceps tendinopathy, which was associated with increased symptoms. Tendinosis was also more common in swimmers with a positive sulcus sign, suggesting a role for shoulder laxity.   Click here to read the article.
