Little epidemiological research on characteristics of upper extremity injuries resulting from snowboarding has been conducted, particularly in relation to snowboarding stance, falling direction, and the side of the body where the injury occurs. ⋯ Two snowboarding stances as well as 2 falling directions had a significant influence on the frequency of the injured side in the upper extremity.

Most patients experience a significant reduction in pain after rotator cuff repair. However, there is currently no method to predict the level of pain reduction that each patient will experience. This report explores the usefulness of the modified impingement test for prognosis in cases of rotator cuff repair. ⋯ The amount of pain reduction after the modified impingement test preoperatively correlated with the improvement of pain after rotator cuff repair. This simple preoperative test could help patients understand the subjective level of pain reduction that they may experience after rotator cuff repair.

Repair of the medial patellofemoral ligament (MPFL) for acute patellar instability has recently become popular, with good clinical success rates reported in the literature. Usually, a lateral retinacular release (LRR) is added to the medial repair in an effort to "rebalance" the patella. In the native knee, however, isolated LRR reduces the force required to displace the patella laterally and may be an undesirable component of instability surgery. ⋯ According to this study, LRR may not be routinely appropriate as a part of the stabilizing procedure to address acute patellar dislocation when the MPFL is avulsed from the patella.

Randomized Controlled Trial
Two- to 4-year follow-up to a comparison of home versus physical therapy-supervised rehabilitation programs after anterior cruciate ligament reconstruction.
There have been no long-term follow-up studies comparing a predominantly home-based rehabilitation program with a standard physical therapy program after anterior cruciate ligament (ACL) reconstruction. Demonstrating the long-term success of such a cost-effective program would be beneficial to guide future rehabilitation practice. ⋯ This long-term study upholds the short-term findings of the original randomized clinical trial by demonstrating that patients who participate in a predominantly home-based rehabilitation program in the first 3 months after ACL reconstruction have similar 2- to 4-year outcomes compared with those patients who participate in a more clinically supervised program.

Comparative Study
Comparison of single- and double-bundle anterior cruciate ligament reconstructions in restoration of knee kinematics and anterior cruciate ligament forces.
Anterior cruciate ligament (ACL) deficiency alters 6 degrees of freedom knee kinematics, yet only anterior translation and internal rotation have been the primary measures in previous studies. ⋯ Both single-bundle and double-bundle techniques cannot restore the rotational laxities and the ACL force distributions of the intact knee.
