Activity recommendations after total hip and knee arthroplasty: a survey of the American Association for Hip and Knee Surgeons.

There are limited data to guide surgeon recommendations regarding activities after total joint arthroplasty. The present study aims to better clarify the current community standards. A questionnaire was distributed to the members of the American Association for Hip and Knee Surgeons attending the 2007 annual meeting inquiring about recommendations for 15 activities for patients with total hip arthroplasty or total knee arthroplasty. One hundred thirty-nine surveys were returned. Spearman rank correlation was used to analyze the data. More than 95% of the responses placed no limitations on low-impact activities including level surface walking, stair climbing, level surface bicycling, swimming, and golf. Higher-impact activities were more commonly discouraged, although there was considerable variability. Recommendations after total hip arthroplasty were more liberal compared to those after total knee arthroplasty. Higher-volume surgeons tended to be more liberal in their recommendations. No responder indicated that there was strong scientific evidence for their recommendations. Investigations are needed to elucidate the long-term effects of higher load and/or higher cycle activities on total joint arthroplasty.
