With an active aging population, more patients expect to return to previous activities and work after surgery. This was a retrospective review of consecutive patients who underwent shoulder hemiarthroplasty from 2007 to 2013, to determine the rate and timing to return of sports and employment after shoulder hemiarthroplasty. In this hemiarthroplasty cohort, there was a 67.2% rate of return to 1 or more sports at an average of 6.5 months postoperatively. Patients older than 65 years experienced similar improvements in ASES scores compared with patients younger than 65 years, although absolute scores were lower on average. Those who returned to higher demand sports were younger on average. Of patients working preoperatively, 69.4% returned to their previous employment at an average of 1.4 months. Patients who did not return to employment had significantly higher body mass index on average. These findings will help surgeons manage expectations of shoulder hemiarthroplasty candidates preoperatively.

Microfracture is the most commonly applied arthroscopic marrow stimulation procedure. This controlled laboratory study found that small-diameter microfracture awls improve articular cartilage repair in the translational sheep model more effectively than do larger awls. These data support the use of small microfracture instruments for the surgical treatment of cartilage defects and warrant prolonged clinical investigations.

As the demand increases for demonstration of competence in surgical skill, the need for validated assessment tools also increases. The results of this study provide evidence that the performance of an ACLR in a dry model is a reliable method of assessing a resident's knowledge of the steps and instrumentation required, and the method shows evidence of validity.

Accumulating case reports have described tendon rupture in men who use anabolic-androgenic steroids (AAS). However, no controlled study has assessed the history of tendon rupture in a large cohort of AAS users and comparison nonusers. AAS abusers, compared with otherwise similar bodybuilders, showed a markedly increased risk of tendon ruptures, particularly upper-body tendon rupture.

Articular reconstruction is recommended for some unstable capitellar osteochondritis dissecans (OCD) lesions. Capitellar osteochondral autograft transplantation (OAT) through an open approach for optimal visualization and perpendicular graft implantation has been advocated. However, arthroscopic capitellar OAT may achieve the same treatment goals with decreased morbidity and ability to treat the entire joint for pathologic changes.
