WOMAC before, and at one year and 3.6 years (26–65 months) after THR for OA. Mean scores and (standard deviations) of the three WOMAC subscales for all patients investigated and operated on with cemented total hip replacement and hybrid total hip replacement. The scale is 0–100, worst to best.
WOMAC subscale | Preop Cemented (N = 65) | Preop Hybrid (N = 29) | 1 year Postop Cemented (N = 90) | 1 year Postop Hybrid (N = 42) | 3.6 years Postop Cemented (N = 139) | 3.6 years Postop Hybrid (N = 57) |
Pain | 45.3 (17.9) | 44.8 (15.9) | 84.4 (17.1) | 84.1 (18.1) | 81.0 (20.1) | 84.2 (21.0) |
Stiffness | 37.7 (16.6) | 42.0 (15.7) | 75.8 (20.5) | 81.8 (16.6) | 76.1 (22.0) | 80.7 (22.3) |
Function | 37.1 (15.5) | 41.8 (12.5) | 75.4 (18.0) | 83.0 (16.1) | 71.3 (21.7) | *81.2 (20.4) |
* = p < 0.05 hybrid vs. cemented THR for each observation time.
