Ankle sprains are the most common sports-related injury, associated with a high rate of recurrence and societal costs. Recent studies have emphasized the effectiveness of both neuromuscular training and bracing for the secondary prevention of ankle sprains. Bracing was found to be the dominant secondary preventive intervention over both neuromuscular training and the combination of both measures.   Click here to read the article.

A Hill-Sachs lesion is a common injury associated with anterior glenohumeral instability, and a Hill-Sachs lesion that engages with the anterior glenoid rim is 1 factor related to recurrent instability. In a cadaveric study in 2007, a new concept, the glenoid track, was proposed to evaluate the risk of engagement of Hill-Sachs lesions with the glenoid. The existence and widths of the glenoid track were confirmed in vivo.   Click here to read the article.

The effect of platelet-rich plasma (PRP) on chondrocytes has been studied in cell and tissue culture, but considerably less attention has been given to the effect of PRP on synoviocytes. Fibroblast-like synoviocytes (FLS) compose 80% of the normal human synovium and produce cytokines and matrix metalloproteinases that can mediate cartilage catabolism. Treatment of synovial cells with LR-PRP and RBCs resulted in significant cell death and proinflammatory mediator production.   Click here to read the article.

The presence of a cam deformity represents a significant risk factor for the development of hip pain. An elevated alpha angle at the 1:30 clock position and decreased internal rotation are associated with an increased risk of developing hip pain. However, not all patients with a cam deformity develop hip pain, and further research is needed to better define those at greater risk of developing degenerative symptoms.   Click here to read the article.

There is a high rate of RTP in professional baseball after UCL reconstruction. Performance declined before surgery and improved after surgery. When compared with demographic-matched controls, patients who underwent UCL reconstruction had better results in multiple performance measures. Reconstruction of the UCL allows for a predictable and successful return to the MLB.   Click here to read the article.

Femoral tunnel enlargement after MPFL reconstruction is common, with patients with patella alta at an increased risk. The influence of tunnel malposition and trochlear dysplasia on this condition requires further research. Recurrent instability and patient-reported outcome scores are not affected by tunnel enlargement.   Click here to read the article.

Early recognition of the clinical signs of ruptures of the pectoralis major muscle (PMM) in athletes by orthopaedic surgeons, physical therapists, and physical trainers may prove to be critical for patient access to surgical treatment while the injury is still in the acute phase.  Total ruptures of the PMM exhibit better outcomes with surgical treatment than with nonoperative treatment based on the Bak criteria in athletes.   Click here to read the article.

Multiple concussions have been associated with prolonged symptoms, recovery time, and risk for future concussions. However, very few studies have examined the effect of multiple concussions on neurocognitive performance and the recently revised symptom clusters using a large database. Concussed athletes with a history of ≥3 concussions take longer to recover than athletes with 1 or no previous concussion. Future research should concentrate on validating the new symptom clusters on multiple concussed athletes, examining longer recovery times (ie, >8 days) among athletes with multiple concussions.   Click here to read the article.

It is commonly accepted that the anterolateral (AL) bundle of the posterior cruciate ligament (PCL) is tight in flexion and that the posteromedial (PM) bundle is tight in extension. However, a recent in vivo study showed that both bundles were tight in extension. Both bundles of the PCL may serve a greater functional role in flexion than in extension. The PM bundle might be more important for the control of rotation than the AL bundle. Posterior translation at 90° of knee flexion could be the most stressful condition for both bundles of the PCL, which may have implications for an injury mechanism.   Click here to read the article.

While a vast body of literature exists describing biceps tenodesis techniques and evaluating the biomechanical aspects of tenodesis locations or various implants, little literature presents useful clinical outcomes to guide surgeons in their decision to perform a particular method of tenodesis. Both ASPBT and OSPBT yield excellent clinical and functional results for the management of isolated superior labrum or long head of the bicepslesions. No significant differences in clinical outcomes as determined by several validated outcome measures were found between the 2 tenodesis methods, nor were any significant range of motion or strength deficits noted at a minimum 2years postoperatively.   Click here to read the article.
