共有344例患者接受双侧全膝关节置换术（TKR），每侧使用不同的假体。采用前后交叉韧带保留型（ACL-PCL）、后交叉韧带保留型（PCL）、内侧或外侧枢轴型（MLP）和后交叉韧带替代型（PS）4种膝关节假体，所有患者均获得良好或优秀的效果。所有假体的活动范围、疼痛缓解、对线和稳定性均无差异，46例患者中有41例（89%）首选ACL-PCL而非PS膝关节，35例患者中有27例（77%）首选MLP膝关节而非PS膝关节。在一侧为ACL-PCL膝关节，另一侧为MLP的患者中，相同数量的患者更喜欢每种类型。34例（79%）患者首选MLP膝关节而非PCL。同样首选PS和PCL膝关节。双侧全膝关节置换术患者更喜欢保留交叉韧带或用内侧或外侧枢轴假体替代。
A total of 344 patients underwent bilateral total knee replacement (TKR) using a different prosthesis on each side. Four knee prostheses were used: anterior and posterior cruciate-retaining (ACL-PCL), posterior cruciate-retaining (PCL), medial or lateral pivot (MLP), and posterior cruciate-substituting (PS).All patients had good or excellent results. The range of movement, relief from pain, alignment, and stability did not vary among any of the prostheses.Forty-one of 46 patients (89%) preferred the ACL-PCL to the PS knee and 27 of 35 patients (77%) the MLP knee to the PS knee. Of the patients with an ACL-PCL knee on one side and a MLP on the other, an equal number preferred each type. The MLP knee was preferred to the PCL by 34 (79%) patients. PS and PCL knees were preferred equally. Patients with bilateral TKRs preferred retention of both their cruciate ligaments or substitution with a medial or lateral pivot prosthesis.
