Implication

Randomized trial finds treat-to-target physical therapy does not improve functional outcomes over usual care after hip or knee arthroplasty, suggesting standard rehabilitation remains sufficient.

Key Points

To evaluate whether a personalized, treat-to-target postoperative physical therapy strategy improves functional recovery compared to usual care following primary total hip or knee arthroplasty.
Conducted a nationwide cluster randomized superiority trial across 18 hospitals enrolling 624 patients (312 undergoing primary THA and 312 undergoing primary TKA).
Hospitals were randomized to implement either a personalized treat-to-target physical therapy strategy or standard postoperative physical therapy.
Physical functioning was measured preoperatively and at 6, 12, 24, and 52 weeks, with the primary endpoint analyzed at 3 months using HOOS-PS and KOOS-PS marginal models.
In the THA cohort, the 3-month change in HOOS-PS score was 19.9 (95% CI: 17.8 to 22.1) in the treat-to-target group versus 18.2 (95% CI: 16.0 to 20.5) in the usual care group, with no statistically significant difference.
In the TKA cohort, the 3-month change in KOOS-PS score was 31.3 (95% CI: 29.3 to 33.4) in the treat-to-target group versus 31.1 (95% CI: 29.0 to 33.2) in the usual care group, showing no statistically significant between-group difference.
