Comparison of shoulder replacement to treat osteoarthritis secondary to instability surgery and primary osteoarthritis: a retrospective controlled study of patient outcomes

We hypothesized that osteoarthritis developing after instability surgery is radiographically similar to primary arthritis and that arthroplasty provides comparable outcomes in patients with these two types of osteoarthritis.
