First, we aimed to investigate the ability of a single bone-patellar tendon-bone graft placed in the anatomic center of the femoral and tibial attachment sites to restore normal tibiofemoral compartment translations and tibial rotation. Second, we aimed to investigate what combination of anterior load and internal rotation torque applied during a pivot-shift test produces maximal anterior tibiofemoral subluxations. ⋯ This study provides in vitro evidence to support the clinical use of single-graft ACL reconstructions in restoring tibiofemoral compartment translations. It also shows the advantage of describing ACL insufficiency in terms of medial and lateral compartment subluxations as compared with the common approach of describing changes in central tibial translations and rotations.

To conduct a systematic review of overlapping meta-analyses comparing treatment of knee osteoarthritis (OA) with intra-articular viscosupplementation (intra-articular hyaluronic acid [IA-HA]) versus oral nonsteroidal anti-inflammatory drugs (NSAIDs), intra-articular corticosteroids (IA-corticosteroids), intra-articular platelet-rich plasma (IA-PRP), or intra-articular placebo (IA-placebo) to determine which meta-analyses provide the best current evidence and identify potential causes of discordance. ⋯ Level IV, systematic review of Level I to IV studies.
-
To investigate the diagnostic performance of magnetic resonance imaging (MRI) and clinical provocative tests on injuries to the triangular fibrocartilage complex (TFCC), the scapholunate (SL) ligament, and the lunotriquetral (LT) ligament. ⋯ Level II, systematic review of Level II diagnostic studies.
-
To investigate demographic trends in elbow arthroscopy over time, as well as to query complication rates requiring reoperation associated with these procedures. ⋯ Level IV, therapeutic case series.

While the apprenticeship model for surgical training is a long-standing gold standard worldwide, proficiency-based progression (PBP) training proves significantly superior. The combination of a metrics tool describing procedural steps and errors with a simulator model or cadaveric training, results in a measurement tool that not only judges but serves to improve surgeon skill.
