Objective: To investigate the effects of knee flexion range of motion and knee flexion range of motion in hip extension (knee flexion E value) on the maximum knee flexion angle during the swing phase (Sw angle) after total knee arthroplasty (TKA).
Methods: Knee flexion range of motion and knee flexion E value were measured preoperatively and at hospital discharge, and the Sw angle was measured at hospital discharge. The factors affecting the Sw angle were studied, taking the Sw angle as the dependent variable, and the knee flexion range of motion and knee flexion E value at hospital discharge as the independent variables. The differences of knee flexion range of motion and knee flexion E value between the preoperatively stage and at hospital discharge were also examined.
Results: The knee flexion E value was extracted as a factor affecting the Sw angle. The knee flexion E value showed a significant decrease from the preoperative stage to hospital discharge.
Conclusion: We speculated that the knee flexion E value may affect the Sw angle, and it was suggested that in order to improve gait after TKA, there is a need to assess and intervene with regard to not only knee flexion range of motion, but also knee flexion E value.
