Shoulder arthroplasty for the young, active patient.

Patients younger than 55 years with degenerative conditions of the glenohumeral joint represent a unique population that can be treated with shoulder arthroplasty. Certain challenges related to this cohort may include greater patient expectations, higher functional demands, soft-tissue contracture from previous surgery, and glenoid bone loss. Surgical treatment options include unconstrained total shoulder arthroplasty; hemiarthroplasty; humeral head resurfacing alone; hemiarthroplasty with concentric reaming of the glenoid; and hemiarthroplasty with adjunctive biologic glenoid resurfacing with autogenous fascia lata, Achilles tendon allograft, or meniscal allograft.
