BIOMECHANICAL EFFECTS OF KNEELING WITH POSTERIOR CRUCIATE RETAINING AND POSTERIOR CRUCIATE SUBSTITUTING TOTAL KNEE ARTHROPLASTY

摘要

Kneeling is an activity that is important in certain occupations and recreational activities. Culturally, kneeling plays a large role in Middle Eastern and Asian countries, where activities of daily living require the ability to kneel and achieve deep knee flexion.rnIt has been shown that kneeling at higher knee flexion angles after total knee arthroplasty (TKA) has a smaller effect on patellofemoral joint contact area and pressure than kneeling at lower flexion angles.1 However, despite the importance of the posterior cruciate ligament (PCL) for resisting posterior translation, the effects of kneeling in posterior cruciate ligament retaining (CR) and substituting (PS) TKA have not been determined. Therefore, the objective of this study was to quantify the tibiofemoral contact areas, pressures, and kinematics with kneeling in CR and PS TKA.
