The incidence of complications, the need for secondary surgical procedures, and the mortality rate associated with bilateral replacement of the knee performed simultaneously, performed during the same hospitalization, or performed during separate hospitalizations were compared with those after unilateral replacement of the knee. The incidence of complications after 290 simultaneous bilateral procedures was 9.3 per cent, which compares favorably both with the incidence of 7.0 per cent after 228 bilateral procedures that were done during the same hospitalization and incidence of the 12.0 per cent after 234 bilateral procedures that were performed during separate hospitalizations. The incidence for each of these groups compares favorably with the incidence of complications of 11.0 per cent after 501 unilateral procedures. The incidence of reoperation was 2.4, 4.8, 8.5, and 5.6 per cent, respectively, in the four groups, and the incidence of mortality was 5.5, 0.9, 3.8, and 7.0 per cent. None of these differences were statistically significant. These data indicate that the incidence of morbidity and mortality that is associated with simultaneous bilateral total knee arthroplasty is no greater than when the procedure is performed during the same hospitalization or separate hospitalizations.
对同时进行双侧膝关节置换术、在同一住院期间进行双侧膝关节置换术或在不同住院期间进行双侧膝关节置换术的并发症发生率、二次手术需求及死亡率，与单侧膝关节置换术后的情况进行了比较。290例同期双侧手术的并发症发生率为9.3%，与228例在同一住院期间进行的双侧手术并发症发生率7.0%以及234例在不同住院期间进行的双侧手术并发症发生率12.0%相比，都更具优势。这些组中的每一组的发生率与501例单侧手术并发症发生率11.0%相比，都更具优势。四组的再次手术发生率分别为2.4%、4.8%、8.5%和5.6%，死亡率分别为5.5%、0.9%、3.8%和7.0%。这些差异均无统计学意义。这些数据表明，同期双侧全膝关节置换术的发病和死亡率并不高于在同一住院期间或不同住院期间进行该手术的情况。
