背景：与标准后交叉韧带保留全膝关节置换术（TKA）相比，对保留部分前十字韧带（PKA）和联合部分膝关节置换术（CPKA）后的前后稳定性知之甚少。方法：在 90N 抽屉下，膝关节弯曲 0-90 度时，用光学跟踪测量 24 个尸体膝关节的前后胫骨平移。在 PKA、CPKA（内侧和外侧双室和双单髁）以及后交叉保留 TKA 之前和之后对膝盖进行测试。通过重复测量方差分析和事后 t 检验，将关节成形术状态在每个屈曲角度下的胫骨前后平移与原生膝关节和彼此进行比较。结果：单间室和双间室关节成形术状态与原生膝关节和彼此之间具有相似的松弛度，= .199）。与原生膝关节相比，双单髁关节置换术导致高屈曲角度下胫骨前移增加 6 至 8 毫米（P
Background: Little is known regarding anterior-posterior stability after anterior cruciate ligament preserving partial (PKA) and combined partial knee arthroplasty (CPKA) compared to standard posterior cruciate-retaining total knee arthroplasty (TKA).Methods: The anterior-posterior tibial translation of twenty-four cadaveric knees was measured, with optical tracking, while under 90N drawer with the knee flexed 0-90 degrees. Knees were tested before and after PKA, CPKA (medial and lateral bicompartmental and bi-unicondylar), and then posterior cruciate retaining TKA. The anterior-posterior tibial translations of the arthroplasty states, at each flexion angle, were compared to the native knee and each other with repeated measures analyses of variance and post-hoc t-tests.Results: Unicompartmental and bicompartmental arthroplasty states had similar laxities to the native knee and to each other, with = .199). Bi-unicondylar arthroplasty resulted in 6-to 8-mm increase of anterior tibial translation at high flexion angles compared to the native knee (P
