Humeral resurfacing hemiarthroplasty with meniscal allograft in a young patient with glenohumeral osteoarthritis.
METHODS
Case report.


BACKGROUND
Management of glenohumeral joint osteoarthritis in young, active patients is challenging due to the significant functional limitations and progression of the disease, coupled with the limited lifespan of prosthetic implants presently in use. The purpose of this report is to present the detailed rehabilitation program and outcome of a patient who suffered an initial glenohumeral dislocation and, following multiple surgical interventions, required shoulder hemiarthroplasty and biologic glenoid resurfacing to return to function.


METHODS
An objectively based rehabilitation protocol was used for this patient following shoulder hemiarthroplasty. Data collected included passive and active range of motion, isometric rotational strength, and functional outcome scores to include the Single Assessment Numeric Evaluation (SANE) and American Shoulder Elbow Surgeons (ASES) outcome measures.


RESULTS
Progressive improvements in active and passive range of motion were documented at numerous points during postoperative rehabilitation, including 1 and 2 years postoperatively. The patient's initial functional outcome scores improved from 2/100 to 90/100 in the SANE and from 17/100 to 85/100 for the ASES rating scales. At 2 years postsurgery the SANE score was 60/100 and ASES 68/100.


CONCLUSIONS
Early postoperative range of motion exercises performed in a range protecting the subscapularis, coupled with a progressive program of rotator cuff and scapular strengthening exercises, resulted in decreased pain, improved range of motion, and return to work in a limited capacity following hemiarthroplasty with biologic glenoid resurfacing. Further research in series of patients following this procedure will help to establish optimal treatment guidelines and prognosis for young active patients with severe glenohumeral joint osteoarthritis.
