A total of 108 men and women scheduled for total hip arthroplasty (THA) or total knee arthroplasty (TKA) were
randomized to a 6-week exercise or education (control) intervention immediately prior to surgery. We assessed outcomes
through questionnaires and performance measures. Analyses examined differences between groups over the preoperative
and immediate postoperative periods and at 8 and 26 weeks postsurgery.
