Comparative Study
Normative values for the KOOS and WOMAC in a young athletic population: history of knee ligament injury is associated with lower scores.
The use of patient-reported outcome measures to assess clinical outcomes after injury and surgery has become common in treating young athletes with orthopaedic injuries; however, normative data for these measures are limited and often include a wide range of ages and activity levels. ⋯ Normative values for all KOOS scales suggest a high level of functioning among participants with no history of knee ligament injury. Despite meeting the medical standards for military service, participants with a history of knee ligament injury had significantly lower KOOS and WOMAC scores upon entry to military service.

A recent one-step arthroscopic technique based on bone marrow-derived cell transplantation has achieved good results in repairing osteochondral lesions of the talus (OLTs), overcoming some of the drawbacks of older techniques. ⋯ One-step repair of OLTs had good clinical results that were durable over time, even though there was a slight decrease in AOFAS score at the latest follow-up. The quality of the regenerated tissue detected by MRI T2 mapping directly correlated with the clinical results.

Anterior cruciate ligament (ACL) injuries are a serious problem, with a high incidence and serious consequences. Published clinical screening tests are based on 2-legged and controlled drop jumps, but ACL injuries are known to occur in single-legged landings and sidestep cutting, where the load is predominantly distributed to a single leg. ⋯ Knee valgus angles during drop jumps do not predict knee abduction moments during sidestep cutting. The moderate correlation of knee valgus angles in drop jumps and sidestep cutting indicates that this measure may be more relevant for screening efforts.

Randomized Controlled Trial
Treatment of lateral epicondylitis with platelet-rich plasma, glucocorticoid, or saline: a randomized, double-blind, placebo-controlled trial.
Lateral epicondylitis (LE) is a common musculoskeletal disorder for which an effective treatment strategy remains unknown. ⋯ Neither injection of PRP nor glucocorticoid was superior to saline with regard to pain reduction in LE at the primary end point at 3 months. However, injection of glucocorticoid had a short-term pain-reducing effect at 1 month in contrast to the other therapies. Injection of glucocorticoid in LE reduces both color Doppler activity and tendon thickness compared with PRP and saline.

Comparative Study
Injury patterns at a large Western United States ski resort with and without snowboarders: the Taos experience.
Differences in injury patterns among alpine skiers and snowboarders have previously been recognized, and controversy remains about the safety implications that snowboarding may pose to a ski resort. A change of policy at Taos Ski Valley provides a unique and modern perspective on the effect that snowboarders have on ski resort injuries. ⋯ In this study, there was a small but statistically significant increase in the likelihood of injury with the addition of snowboarding to a large ski resort. It is likely that factors such as younger demographic, elevated risk-taking behavior, or increased mountain crowding are involved. The difference in injuries is largely because of a significant increase in distal radius fractures, closed head injuries, and acromioclavicular separations. On mountain safety precautions such as widening of runs and streamlining of high traffic areas, training medical providers to recognize and treat sport-specific injuries, and promoting the use of wrist guards and helmets may be useful in reducing the effect that snowboarders have on ski resort injuries.
