目的探讨全膝关节置换术后低位髌骨的诊断与治疗。方法回顾分析1例全膝关节置换术后低位髌骨的临床资料,并进行文献回顾分析。结果 1例55岁女性患者,右膝关节置换术后1年,以膝前痛、膝关节屈曲受限收入院。经膝关节正侧位X线片确诊为右膝关节置换术后低位髌骨,入院后行右侧髌骨表面置换及髌韧带松解术,有效地解除膝前痛及膝关节屈曲活动受限的症状,术后随访HSS评分显示患者膝关节疼痛、功能、关节活动度明显改善。结论全膝关节置换术后低位髌骨并不常见,正确的诊断与治疗对改善患者术后生活质量尤为重要。

Objective To explore the diagnosis and treatment of patella baja after total knee arthroplasty. Methods Retrospective analysis of clinical data of one case about patella baja after total knee arthroplasty was carded out. Results one 55-year-old female patient was hospitalized due to pain in the anterior aspect of the knee and limited motion range of the knee a year after right knee replacement surgery. The patient was diagnosed as right patella baja by lateral plain radiography and then underwent right patellar ligament lysis and right patellar surface replacement, which effectively relieved knee pain and knee flexion activity limitation. The patient was followed up and according to HSS score, the knee pain, knee function, range of motion of knee all improved significantly. Conclusion Low patella after total knee arthroplasty is not common; the correct diagnosis and treatment to improve the quality of life of patients is particularly important.
