Garner AJ, Dandridge OW, Amis AA, et al. - This study was carried out to assess anterior-posterior tibial translation of twenty-four cadaveric knees, with optical tracking, while under 90N drawer with the knee flexed 0-90°. Researchers tested knee before and after PKA, CPKA (medial and lateral bicompartmental and bi-unicondylar), and then posterior cruciate-retaining total knee arthroplasty (TKA). Researchers compared anterior-posterior tibial translations of the arthroplasty states, at each flexion angle, with the native knee and each other with repeated measures analyses of variance and post-hoc t-tests. According to the findings, the anterior-posterior tibial translation did not differ from native laxity after PKA and CPKA in a cadaveric study. Posterior cruciate ligament–preserving TKA showed elevated laxity, especially in anterior tibial translation.
