Pseudoparalysis From a Massive Rotator Cuff Tear Is Reliably Reversed With an Arthroscopic Rotator Cuff Repair in Patients Without Preoperative Glenohumeral Arthritis.

Background: Pseudoparalysis is defined as active forward flexion less than 90° with full passive motion. There is controversy about the ideal surgical management of a massive rotator cuff tear with pseudoparalysis.

Purpose/hypothesis: The purpose of this study was to prospectively analyze the ability to reverse pseudoparalysis with an arthroscopic rotator cuff repair (ARCR).
