HealthDay News — For patients undergoing total hip arthroplasty (THA), formal outpatient physical therapy (OPT) is not associated with improved outcomes, according to a study presented at the annual meeting of the American Academy of Orthopaedic Surgeons, held from March 1 to 5 in Orlando, Fla.
Brian Urbani, from the Rothman Institute in Philadelphia, and colleagues randomized 77 patients who underwent THA to receive 2 months of formal OPT (39 patients), with 2 to 3 sessions per week, or no formal OPT (38 patients), with patients following a prescribed exercise program on their own. Before surgery and at 1 and 6 months postoperatively, functional scores were recorded.
The researchers observed no significant between-group differences in any measured outcomes at 1 or 6 months postoperatively. The Harris Hip Score was 67.67 ± 3.0 and 80.19 ± 4.33 for the formal OPT group, compared with 71.26 ± 3.24 and 84.68 ± 3.32 for the no OPT group at 1 month and 6 months, respectively.
There were no significant differences between the groups in the Western Ontario and McMaster Universities Arthritis Index or in the Short Form-36 scores at either postoperative interval.
“These findings suggest that formal OPT is not superior to prescribed, patient-directed home exercises,” the authors wrote. “Based on the findings of this study, we have moved away from routinely prescribing formal OPT for all patients after THA.”
