ABSTRACT
PURPOSE:
Although single-radius (SR) designs have a theoretical advantage in quadriceps recovery following total knee arthroplasty (TKA), there has been a paucity of objective evaluation studies. MATERIALS ANDMETHODS:
One hundred and twenty minimally invasive TKAs were prospectively randomized by a single surgeon into 2 groups SR design TKA group and multi-radius design TKA group. Quadriceps force and power were assessed using a dynamometer, and clinical data were investigated preoperatively and 6 weeks, 3 months, 6 months and 1 year postoperatively.RESULTS:
There were no differences between two groups in quadriceps recovery and clinical results throughout the follow-up period. Furthermore, the proportion of patients whose postoperative quadriceps force and power reached preoperative level was similar in both groups.CONCLUSIONS:
Femoral component design itself would not significantly influence quadriceps recovery after TKA.
