Comparative Study
Muscle flexibility as a risk factor for developing muscle injuries in male professional soccer players. A prospective study.
Muscular tightness is frequently postulated as an intrinsic risk factor for the development of a muscle injury. However, very little prospective data exist to prove this. ⋯ Preseason hamstring and quadriceps muscle flexibility testing can identify male soccer players at risk of developing hamstring and quadriceps muscle injuries.

Randomized Controlled Trial Clinical Trial
A prospective randomized study of patellar versus hamstring tendon autografts for anterior cruciate ligament reconstruction.
Bone-patellar tendon-bone graft has been the most commonly used graft material in anterior cruciate reconstructions, but there has been increasing use of hamstring tendon grafts. However, no existing clinical studies show adequate support for the choice of one graft over the other. ⋯ Equal results were seen for patellar and hamstring tendon autograft anterior cruciate ligament reconstructions at 2 years after surgery. Both techniques seem to improve patients' performance.

The best choice of graft tissue for use in anterior cruciate ligament reconstruction has been the subject of debate. ⋯ Patellar tendon autografts had a significantly lower rate of graft failure and resulted in better static knee stability and increased patient satisfaction compared with hamstring tendon autografts. However, patellar tendon autograft reconstructions resulted in an increased rate of anterior knee pain.

Chronic wrist pain affects up to 79% of young gymnasts. Distal radial growth plate injury and positive ulnar variance have also been reported in this population. ⋯ Radiographic findings of distal radial physeal injury are associated with wrist pain among young nonelite gymnasts.

Access to the inferior glenohumeral joint of the shoulder is very limited through the traditional 2- or 3-o'clock anterior portals. ⋯ The 7-o'clock portal is a safe and effective technique for use by shoulder surgeons.
