It is more likely than not that active individuals can return to their preoperative level of sports participation following total shoulder arthroplasty, according to a study presented here.

Approximately 94% of patients will return to sports, and 86% will return to their preoperative sport — 80% at the preoperative intensity according to a study presented at the American Society for Sports Medicine 2009 Annual Meeting. Unrestricted activity can be allowed at 6 months, and low-impact low sports are suggested.

Return to sport may become a benchmark of these arthroplasty surgeries.

To assess activity levels following total shoulder arthroplasty (TSA), researchers sent questionnaires to 304 patients who received unconstrained TSA; 165 questionnaires were returned and 87 of those patients indicated that they regularly participated in sports.

The average age was 58.5 years and the minimum follow-up was 1 year. Preoperative diagnosis was commonly osteoarthritis, but they also saw rheumatoid arthritis and osteonecrosis.

The patients received the same prosthesis, which had an anatomic stem and a cemented all-polyethylene glenoid component. All patients received a tenotomy or tenodesis procedure.

Rehabilitation involved light swim at 1 to 2 weeks, active external rotation at 4 weeks, water therapy at 5 to 8 weeks, and unrestricted activity beyond 6 months. Restricted behavior before 6 months included putting, half-swing golf shots from the tee at 3 months and full swing at 4 months.

The preoperative sports that patients participated in included walking, hunting and fishing, golf, swimming, cycling, aerobics, tennis, jogging and waterskiing.

At minimum 1 year follow-up, 94.4% said they returned to the sport, with 86% returning to the sport they played preoperatively, and 80% who did return reported the same intensity they had preoperatively.

In terms of postoperative pain, 74% reported no postoperative pain with sports participation, 75% reported no pain after sports participation and 82% reported using no pain medication for any pain related to sport participation.

The subscapularis function is critical in trying to understand if the 80% [return-to-same-intensity rate] would be higher. We know that if they are having subscapularis failures, that can compromise their function.

My comments:

Return to sports does not mean return to unrestricted overhead work. One must be very careful not to expect to return to unrestricted to overhead manual labor after a shoulder replacement.

Thanks.
