Arthroscopic Removal of Chronic Symptomatic Calcifications of the Supraspinatus Tendon Without Acromioplasty Analysis of Postoperative Recovery and Outcome Factors

Background:Little knowledge exists on postoperative recovery of pain and shoulder function following arthroscopic removal of calcific deposits of the supraspinatus tendon (ACDSSP). Certain factors may influence outcome, including acromial morphology.Purpose:To examine postoperative recovery following ACDSSP without acromioplasty and to analyze influential outcome factors.Study Design:Case series; Level of evidence, 4.Methods:This prospective study evaluated 82 patients (105 shoulders) after ACDSSP without acromioplasty. Time periods for postoperative recovery of pain and subjective shoulder function were recorded. The absolute and normalized Constant scores (CSabs and CSnorm, respectively), Oxford Shoulder Score (OSS), DASH score (DS), and subjective shoulder value (SSV) were measured after a mean follow-up of 33.9 months. Analyzed outcome factors included localization of the calcific deposit (CD), acromial morphology, radiographic extent of CD removal, type of nonoperative treatment, and preoperative dur...
