Indications, technique, and results of total shoulder arthroplasty in osteoarthritis

Osteoarthritis is a slowly progressive disease of one or more joints that appears to primarily affect articular cartilage. A joint affected by osteoarthritis develops cartilage thinning and, ultimately, patches of complete cartilage loss. The main symptom of osteoarthritis in the glenohumeral joint is diffuse, achy, and insidiously progressive pain. Total shoulder arthroplasty has become the standard treatment for advanced osteoarthritis of the glenohumeral joint.
