Comparative Study
Repair of large chondral defects of the knee with autologous chondrocyte implantation in patients 45 years or older.
Autologous chondrocyte implantation (ACI) has become an accepted option for the treatment of chondral defects in carefully selected patients. Current recommendations limit this procedure to younger patients, as insufficient data are available to conclusively evaluate outcomes in patients older than 45 years. ⋯ Our results showed a failure rate of ACI in older patients that is comparable with rates reported in younger patient groups. The procedure is associated with a substantial rate of reoperations, mostly for the arthroscopic treatment of graft hypertrophy, similar to that in younger patients.

Muscle weakness, particularly of shoulder external rotation, is common after rotator cuff repair surgery. Neuromuscular electrical stimulation has been shown to be an effective adjunct in the enhancement of muscle recruitment. ⋯ Neuromuscular electrical stimulation may be used concomitantly with exercises to enhance the amount of force production and potentially minimize the inhibition of the rotator cuff after repair surgery.

With more than a million high school athletes playing during the 2006-2007 academic year, basketball is one of the most popular sports in the United States. ⋯ High school basketball injury patterns vary by gender and type of exposure. This study suggests several areas of emphasis for targeted injury prevention interventions.
