Abstract
Aims: Outcomes for a RSP to treat either a previous operated shoulder (revision procedure) was compared to a primary RSP. Methods: 20 Primary RSP (6M, 14F) for an irreparable rotator cuff tear (IRCT) with glenohumeral arthritis/anterior superior arch deþciency and 31 revision RSP (10M, 21F) (previous rotator or cuff surgery, hemi or total shoulder arthroplasty) were evaluated at an average of 24 months postoperatively. Mean age at the time of RSP was 72.3 for primaries 67.2 for revisions. Assessment with pre- and postoperatively SF-36, SST, ASES scores, physical exam, satisfaction surveys, and radiographs was performed. Results: Primary RSP improvements/Revision RSP improvements were: 9.4 sf-36 PCS/6.3 sf-36 PCS, 1.8 SST/1.6 SST, 31.8 ASES/17.5 ASES (p< 0.05), 49.2 elevation/14.2 elevation (p< 0.05) and 57.8 external rotation/30 external rotation. 71.3% Excellent/good/. 56% Excellent/good (p< 0.05), 21.4% satisfactory/33.3% satisfactory, 7.1% unsatisfactory outcome/9.5% unsatisfactory outcome. Complications only occurred in the revisions including component disassociation, glenoid loosening, recurrent instability, and infection. Conclusion: Primary RSP provides predictable improvements in pain and function with minimal complications. Revision RSP has a higher complication rate and improvements in pain and function are less reliable. Conventional shoulder arthroplasty for patients with IRCT with glenohumeral arthritis/anterior superior arch deþciency has resulted in adequate pain relief but functional improvement has not been predictable. Thus, the initial operative selection for these patients must consider the effect of a failed reconstructive attempt on patient outcomes
