Chondrolysis has been observed after shoulder arthroscopy and results in severe glenohumeral complications. ⋯ Chondrolysis is a devastating complication of arthroscopic shoulder surgery that can result in long-term disabling consequences. Further research is required to specifically identify causative factors. Until this is a available, we strongly advise against the use of large doses of intra-articular placement of local anesthetics.

Comparative StudyEffects of flexor-pronator muscle loading on valgus stability of the elbow with an intact, stretched, and resected medial ulnar collateral ligament.
The medial ulnar collateral ligament (MUCL) is an important passive stabilizer to the valgus stresses that athletes experience during overhead throwing motion. However, the role of the flexor-pronator muscles as active stabilizers to valgus stress is not well defined in the literature. The objectives of this study were to quantify the relative contribution of the individual flexor-pronator muscles to valgus stability of the elbow and how this relationship was affected by ligament status. ⋯ The FDS, PT, and FCU are all active stabilizers of the elbow to valgus stress. The FDS is the biggest contributor amongst the flexor-pronator muscles.

Comparative StudyThe active elevation lag sign and the triangle sign: new clinical signs of trapezius palsy.
Spinal accessory nerve palsy causing trapezius dysfunction can lead to significant disability. Diagnosis is frequently delayed or inaccurate leading to inappropriate treatment. ⋯ Level 2-1; Evidence obtained from well-designed controlled trials without randomization.
