Results of a study of Arthrosurface's OVO® with Inlay Glenoid Shoulder Arthroplasty System demonstrated excellent clinical benefits, including pain relief and increased range of motion in patients with glenohumeral (GH) arthritis.
The retrospective case series included 31 shoulders in 29 patients, with outcomes including the Penn Shoulder Score, visual analog scale for pain, range of motion, radiographic analysis and complications.
Initial results showed that nonspherical humeral head resurfacing, combined with inlay glenoid replacement, is a viable outpatient technique for GH arthritis across patients with concentric and eccentric glenoid morphology. Results showed no significant differences in patient-reported outcomes, including pain relief, function and satisfaction, comparing preoperative concentric with nonconcentric glenoid morphology. A significant improvement in range of motion that was consistent across glenoid stages.
Notably, results indicated improved range of motion vs. traditional stemmed total shoulder arthroplasty in conventional and reverse configurations.
