Pellegrini-Stieda lesion is described as ossification on the origin of medial collateral ligament. We present a case of end-stage knee osteoarthritis with the Pellegrini-Stieda lesion treated by unicompartmental knee arthroplasty (UKA). During the postoperative follow-up, an interesting change occurred such that the ossification lesion disappeared gradually and did not relapse. It is supposed that the disappearance was caused by UKA changing the abnormal biomechanics of the varus osteoarthritic knee.

佩莱格里尼-施蒂达损伤被描述为内侧副韧带起点处的骨化。我们报告一例终末期膝关节骨关节炎合并佩莱格里尼-施蒂达损伤，采用单髁膝关节置换术（UKA）治疗。在术后随访期间，发生了一个有趣的变化，即骨化损伤逐渐消失且未复发。据推测，这种消失是由于单髁膝关节置换术改变了内翻性骨关节炎膝关节的异常生物力学所致。
