Randomized Controlled Trial Multicenter Study Clinical Trial
The effect of a proprioceptive balance board training program for the prevention of ankle sprains: a prospective controlled trial.
Ankle sprains are the most common injuries in a variety of sports. ⋯ Use of proprioceptive balance board program is effective for prevention of ankle sprain recurrences.

In 1998, the National Collegiate Athletic Association legislated a decrease in the number of scrimmages and full-contact practices allowed during the spring season. ⋯ There was and still is a statistically significant increase in spring practice injury risk. The 1998 rule change resulted in an even greater increase in spring practice injury risk. If the goal is to minimize the number of spring practice injuries, it will be best accomplished by limiting the number of scrimmages and limited-contact sessions.

Several techniques have been described for reconstruction of the medial patellofemoral ligament. However, the isometry of the medial patellofemoral ligament has not been studied. ⋯ This study provides a detailed description of the anatomy of the medial patellofemoral ligament, as well as an evaluation of the isometric behavior of the ligament. Application of these data during reconstruction of the medial patellofemoral ligament may help to optimize patellofemoral stability.

Extensor mechanism procedures that decrease the lateral component of the patellar tendon or quadriceps force acting on the patella do not consistently reduce pain. ⋯ Extensor mechanism procedures that restore patellofemoral stability may not provide pain relief.

There are few epidemiologic studies of catastrophic baseball injuries. ⋯ Suggestions for reducing catastrophic injuries in baseball include teaching proper techniques to avoid fielding and baserunning collisions, protecting the pitcher via a combination of screens and/or helmets with faceguards, continued surveillance and modifications of the bat and ball, eliminating headfirst slides, and continued analysis of chest protectors and automatic external defibrillators for commotio cordis.
