Is a formal physical therapy program necessary after total shoulder arthroplasty for osteoarthritis?
OBJECTIVE
A retrospective analysis was conducted of 2 consecutive groups of patients undergoing total shoulder arthroplasty (TSA) for primary osteoarthritis. One group was treated with formal physical therapy (PT), and one group was treated with home-based, physician-guided PT. We hypothesized that patients with a formal postoperative PT protocol would have significantly better postoperative clinical outcomes than patients with no formal PT.


METHODS
Group A (43 patients) had a standard PT program. Group B (38 patients) had a home-based, physician-guided PT program. Clinical outcomes (preoperatively, 3, 6, and 12 months and most recent follow-up) were analyzed. A minimum sample size of 31 patients gives power to detect a 10-point American Shoulder and Elbow Surgeons (ASES) score (alpha=0.05, beta=0.80).


RESULTS
ASES and Simple Shoulder Test (SST) scores significantly improved in both groups at all follow-up periods. Forward flexion and abduction were significantly improved in group B at all time points, whereas an initial improvement in forward flexion and abduction in group A was lost at final follow-up. There were no significant differences in final ASES or SST scores between groups at final follow-up. However, forward flexion, abduction, and the Short Form-36 physical component summary in group B were significantly better than group A at final follow-up. No significant improvements in internal rotation or SF-36 mental component summary were seen within or between the groups at final follow-up. Overall, there was no difference in patient satisfaction, with 88% satisfaction in group A and 95% satisfaction in group B (chi(2)=0.471, P=.4924).


CONCLUSIONS
A home-based, physician-guided therapy program may provide adequate rehabilitation after TSA, allowing for a reduction in cost for the overall procedure.
