The early outcomes of 2 newer-generation posterior cruciate ligament-retaining fixed-bearing total knee arthroplasty (TKA) implant designs were assessed to determine if a single sagittal radius femoral design has an advantage in obtaining earlier knee range of motion and function when compared with a contemporary multiradius femoral design. Total knee arthroplasty patients were prospectively randomized to receive either a single sagittal radius femoral design (n=50) or a multiradius femoral design (n=50). Knee extensor mechanism function after TKA with either a single sagittal radius or multiradius implant was comparable in contemporary posterior cruciate ligament-retaining TKA designs.
评估了两种新一代后交叉韧带保留型固定平台全膝关节置换术（TKA）植入物设计的早期疗效，以确定与当代多半径股骨设计相比，单一矢状半径股骨设计在更早获得膝关节活动范围和功能方面是否具有优势。全膝关节置换术患者被前瞻性随机分为接受单一矢状半径股骨设计（n = 50）或多半径股骨设计（n = 50）。在当代后交叉韧带保留型TKA设计中，使用单一矢状半径或多半径植入物进行TKA后的膝关节伸肌机制功能相当。
