Inlay TSA improves function, reduces pain in patients with glenohumeral arthritis

Published results showed anatomic total shoulder arthroplasty with a non-spherical humeral head and inlay glenoid replacement yielded functional improvements, pain relief and satisfaction in patients with advanced glenohumeral arthritis.
John W. Uribe, MD, and colleagues at Miami Orthopedics and Sports Medicine Institute in Coral Gables, Florida analyzed 36 patients (39 shoulders) who underwent inlay total shoulder arthroplasty (TSA) for advanced glenohumeral osteoarthritis (OA). Among the cohort (mean age of 65.9 years), 93% had grade 3 OA and 7% had grade 2 OA. Outcome measures included American Shoulder and Elbow Surgeons (ASES) score, VAS pain score, range of motion (ROM), patient satisfaction, according to the study.
Uribe and colleagues used the Walch classification to determine preoperative glenoid morphology. Among the cohort, 25.6% of patients had an A1 classification; 25.6% had an A2 classification; 20.5% had a B1 classification; 25.6% had a B2 classification; and 2.6% had a C classification.
Researchers found mean ASES score improved from 30.4 to 77.1; mean VAS pain score improved from 8.1 to 1.5; and patient satisfaction was 9.1 of 10. ROM also improved preoperatively to postoperatively, they noted.
“Treatment of advanced glenohumeral arthritis with inlay TSA resulted in high patient satisfaction, excellent pain relief and functional improvement at an average follow-up of 41 months,” Uribe and colleagues wrote in the study. “No implants were revised during this study, and secondary procedures were limited to one shoulder requiring arthroscopic lysis of adhesions at 2 years,” they added.
