Knee arthroscopy is one of the most common orthopaedic procedures performed in the United States. The publication of a randomized controlled trial of arthroscopy versus sham surgery by Moseley et al in 2002 showed no efficacy and challenged the role of arthroscopy for the treatment of osteoarthritis. ⋯ Randomized controlled trials can be effective in changing orthopaedic surgeon practice.

Comparative Study
Comparison of the acute inflammatory response of two commercial platelet-rich plasma systems in healthy rabbit tendons.
Numerous studies have shown platelet-rich plasma (PRP) preparations differ with respect to the inclusion of certain blood components, which may affect the host's cellular response. ⋯ Platelet-rich plasma injections are frequently prepared using commercial systems and are administered for clinical treatment of chronic tendinopathy. It is important to characterize the cellular responses elucidated by different injection preparations to further understand their effect on tissue healing and aid clinical decision making. Future investigations are necessary to apply these findings to the clinical setting.

Randomized Controlled Trial
The FIFA 11+ program is effective in preventing injuries in elite male basketball players: a cluster randomized controlled trial.
Recently, structured training programs for sports injury prevention ("The 11" and "The 11+") have been validated in soccer. The FIFA 11+ program has not been evaluated in basketball. ⋯ The FIFA 11+ warm-up program is effective in reducing the rates of injuries in elite male basketball players.

Prognostic factors of arthroscopic pull-out repair for a posterior root tear of the medial meniscus.
Repair of a posterior root tear of the medial meniscus (MRT) decreases peak contact pressure by restoring hoop tension and is expected to prevent progression to osteoarthritis. ⋯ At a mean follow-up of 33 months after pull-out repair, extrusion of the meniscus was found to have progressed. Nevertheless, this technique provided patients with a clinical benefit. Outerbridge grade 3 or 4 chondral lesions and varus alignment of >5° were found to independently predict an inferior clinical outcome.
