Superior Capsular Reconstruction Reverses Profound Pseudoparalysis in Patients With Irreparable Rotator Cuff Tears and Minimal or No Glenohumeral Arthritis.

Purpose: The purpose of the study was to investigate the rate and magnitude of return of active forward elevation (aFE) of the arm for patients with severe preoperative elevation dysfunction (less than 45° of aFE and termed profound pseudoparalysis) and massive, irreparable (or partially reparable) rotator cuff tears without arthritis treated with arthroscopic superior capsular reconstruction (SCR).

Methods: The period for this retrospective study was October 2014 to October 2016. Inclusion criteria included patients treated arthroscopically for an incompletely reparable massive rotator cuff tear (2 tendons fully torn or tear dimension > 5 cm), preoperative aFE of less than 45° (profound pseudoparalysis) with full passive elevation, an intact or reparable subscapularis tendon, radiographic classification Hamada 0-3, and 12-month clinical follow-up.

Remplissage Using Interconnected Knotless Anchors: Superior Biomechanical Properties to a Knotted Technique?

Purpose: To evaluate the biomechanical fixation strength and gap formation of 2 different remplissage fixation methods (double pulley knotted construct and interconnected knotless repair construct) in cadaver specimens.

Methods: Seven matched pairs of human cadaveric shoulders were used for testing (mean age, 56 ± 10 years). A shoulder from each matched pair was randomly selected to receive a Hill-Sachs remplissage using either a knotted (No.

Arthroscopic Joint Preservation in Severe Glenohumeral Arthritis Using Interpositional Human Dermal Allograft.

Purpose: To investigate the outcomes of arthroscopic glenoid resurfacing (AGR) for severe glenohumeral arthritis at short- to medium-term follow-up.

Methods: We performed a multicenter retrospective review of consecutive patients undergoing AGR (2005-2013) with a minimum of 2 years' follow-up or until revision. Patients lost to follow-up and those included in a prior study were excluded.

Effectiveness of rosiglitazone in reducing flexion contracture in a rabbit model of arthrofibrosis with surgical capsular release: A biomechanical, histological, and genetic analysis.

Aims: Animal models have been developed that allow simulation of post-traumatic joint contracture. One such model involves contracture-forming surgery followed by surgical capsular release. This model allows testing of antifibrotic agents, such as rosiglitazone.
