Pectoralis major tendon ruptures are commonly described as rare injuries affecting men between 20 and 40 years of age, with generally excellent results after surgical repair. However, this perception is based on a relatively small number of case series and prospective studies in the orthopaedic literature.

Among military personnel, Army soldiers and junior officer/enlisted rank were at highest risk of pectoralis major tendon ruptures, and junior personnel were at highest risk of being unable to return to duty after surgical treatment. Although increasing time from injury to surgery was not a risk factor for treatment failure or inability to return to duty, it did significantly increase the risk of a postoperative complication.

With rising participation in youth sports such as baseball, proximal humeral epiphysiolysis, or Little League shoulder (LLS), is being seen with increasing frequency. However, there remains a paucity of literature regarding the causes, natural history, or treatment outcomes of LLS.

Little League shoulder is being diagnosed with increasing frequency. While most common in male baseball pitchers, the condition can occur in females, youth catchers, other baseball positions players, and tennis players. Concomitant elbow pain may be seen in up to 13%. After rest and physical therapy, recurrent symptoms may occur in a small subset of patients (7%), generally 3 to 6 months after return to sports. Almost one-third of LLS patients had GIRD, and this group had approximately three times higher probability of recurrence compared with those without GIRD.

Short-term outcomes for patients with large, engaging Hill-Sachs lesions who underwent remplissage have demonstrated good results. However, limited data are available for longer term outcomes. The redislocation rate after remplissage was 11.8% at an average of 5 years, with 95.5% of patients returning to full sports at an average of 7 months. For throwing sports, 65.5% of patients complained of decreased range of motion during throwing. The results should be considered preoperatively in candidates for remplissage who are engaged in throwing sports.

Impairments in motor control may predicate the paradigm of chronic ankle instability (CAI) that can develop in the year after an acute lateral ankle sprain (LAS) injury. No prospective analysis is currently available identifying the mechanisms by which these impairments develop and contribute to long-term outcome after LAS. This study found that an inability to complete jumping and landing tasks within 2 weeks of a first-time LAS and poorer dynamic postural control and lower self-reported function 6 months after a first-time LAS were predictive of eventual CAI outcome.

There are limited and inconsistent data regarding return-to-sport outcomes after revision anterior cruciate ligament reconstruction (ACLR). This study hypothesized that return-to-sport rates will be lower after revision ACLR when compared with primary ACLR.

After evaluating a study cohort of 136 eligible patients, this study concluded that return-to-sport rates of patients after revision ACLR were similar to those after their primary surgery but were still lower than the reported rates of ACLR patients who did not need revision surgery. Greater chondral pathologic abnormalities at revision surgery were associated with reduced function at follow-up.
