Hip Arthroscopy and Its Impact on Performance in National Hockey League Players Using Team-Based Advanced Performance Statistics.

Background: Ice hockey players have a high rate of hip pathology, which can lead to hip arthroscopy. Previous studies have not utilized team-based advanced performance statistics in the setting of hip arthroscopy in National Hockey League (NHL) players.

Purpose/hypothesis: The purpose of this study was to use team-based advanced performance statistics to evaluate postoperative performance after hip arthroscopy in NHL players in comparison with their preoperative performance and matched controls of uninjured skaters.

Influence of Dietary Cobalt on Fiber Digestibility and Serum Cobalt and Cobalamin Concentrations in Horses.

The 2007 Horse NRC reduced cobalt (Co) requirements from 0.1 ppm to 0.05 ppm in dietary dry matter, though preliminary research suggested increasing dietary-Co enhanced fiber digestion in horses.

Correlation of Increased Lateral Tibial Slope With Baseline Tibial Position in Intact Knees and Side-to-Side Anterior Tibial Translation for Knees With ACL Tears.

Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.

Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.
