Eighty-four women who underwent total knee arthroplasty were randomized to receive either standard rehabilitation plus Mobilization with Movement (MWM) n=42) or standard rehabilitation alone (n=42). The primary outcome was change in knee flexion range of motion at 6 weeks. Secondary outcomes included knee extension range of motion, pain (VAS at rest and during movement), Timed Up and Go test, 15-meter walk test, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Outcomes were measured at pre-surgery, 3 weeks (post-surgical, before intervention), 6 weeks (after MWM sessions), and 6 months. Overall, the results revealed that the intervention group had significantly greater improvement in knee flexion at both 6 weeks and 6 months compared to the control group. Secondary outcomes showed no statistically significant differences. This suggests that MWM improves short- and medium-term knee flexion in women after TKA but has limited impact on other functional outcomes.
