Data included initial diagnosis and index procedure performed, presenting arthropathy symptoms including duration, and examination findings before revision surgery. Pre\u2010revision imaging was used to assess presence of glenohumeral osteoarthritis and chondromalacia, anchors\/sutures, loose bodies, and labral pathology. The same parameters were recorded intraoperatively during revision surgery. Descriptive statistics were performed for demographic data and means with standard deviations were calculated for continuous data. A McNemar\u2013Bowker test was used to analyze marginal homogeneity between preoperative imaging and intraoperative findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Mean age at presentation was 33.4 \u00b1 11.7 years (range 16\u201059, 17 male patients; 6 female patients). More than one half (13\/23) developed symptoms within 10 months after index arthroscopic procedure (mean 32.2 \u00b1 59.9 months, range &lt;1 to 165.2 months) with 87% presenting with pain and 100% presenting with loss of motion on examination. Plain radiographs demonstrated humeral osteoarthritis in 57% (13\/23) of patients, magnetic resonance imaging (MRI) revealed recurrent labral pathology in 19 of 23 (83%) patients, potential proud implants in 12 of 23 (52%), and loose bodies in 12 of 23 (52%). Intraoperatively, all had evidence of osteoarthritis; 22 of 23 (96%) had prominent implants. Humeral head chondromalacia was present in 21 of 23 patients (91%), the majority of which was linear stripe wear, and 6 of 23 (26%) had severe global glenohumeral osteoarthritis. Statistical analysis revealed a 54.5% (95% confidence interval 0.327\u20100.749) sensitivity of MRI identification of proud implants with a specificity of 100% (95% confidence interval 0.055\u20101).

Implants were implicated in the majority of cases of humeral head chondromalacia. MRI scans may produce false\u2010negative identification of proud implants and can be a poor predictor of the severity of chondromalacia and intra\u2010articular pathology; thus, a high index of clinical suspicion is necessary in patients with motion loss and pain postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of
