| Abstract: | The purpose of this study was to measure the strain in the posterior cruciate ligament as a function of knee flexion angle and posterior tibial slope following total knee arthroplasty with a posterior cruciate ligament-retaining design. Posterior cruciate ligament strain was measured in seven fresh-frozen cadavers for posterior tibial slopes of 10°, 8°, and 5°. For all three levels of tibial slope tested, strain in the posterior cruciate ligament increased with increasing flexion angle to approximately 100° and then decreased with increasing flexion. The strain measured at 8° posterior tibial slope was greater than that measured at 10°, but the difference was not significant. The strain measured at 5° posterior slope was significantly greater than strain measured at both 8° and 10°. This increased strain may result in altered knee kinematics and reduced range of motion at higher flexion angles. |
