Prosthetic total knee replacements rarely dislocate. When dislocation does occur, it is usually in a posterior direction in association with a posterior stabilised, cruciate-sacrificing prosthesis. Neurovascular injury is unusual. In this report, we describe a case of anterior dislocation of a cruciate-retaining total knee replacement in a 67-year-old woman. The dislocation occurred in the absence of overt trauma and resulted in severe neurovascular injury.
人工全膝关节置换术很少发生脱位。当脱位确实发生时,通常是向后脱位,与后稳定型、牺牲交叉韧带的假体有关。神经血管损伤并不常见。在本报告中,我们描述了一名67岁女性的保留交叉韧带全膝关节置换术发生前脱位的病例。脱位发生时没有明显外伤,并导致了严重的神经血管损伤。
