Abstract

Successful posterior cruciate ligament-sparing total knee arthroplasty functions in an equivalent fashion to a contralateral normal limb during the mechanical stresses of stair ascent and descent. Motion and force plate analysis reveal highly symmetric gait patterns. Sagittal angles are greater than previously reported for the total condylar prosthesis and are nearly equal to those recorded for the age-matched normal population.

摘要

成功保留后交叉韧带的全膝关节置换术在上下楼梯的机械应力作用下，其功能与对侧正常肢体相当。运动和测力板分析显示出高度对称的步态模式。矢状角大于先前报道的全髁假体的角度，且几乎与年龄匹配的正常人群记录的角度相等。
