目的:运用X线检查分析第4代牛津单髁膝关节置换术中股骨假体、胫骨假体的位置对治疗膝关节骨性关节炎的近期临床疗效的影响.方法:2018年12月至2020年4月连续纳入在石河子市人民医院就诊的临床诊断为膝关节骨性关节炎的患者,将其中符合纳入及排除标准且最终行牛津单髁膝关节置换术的患者连续入组本研究,并在术后第12个月对入组患者进行影像学检查,根据假体位置分为内侧组、中央组、外侧组.比较三组的临床资料、影像学资料及2011版KSS评分.结果:术后第12个月,中央组的2011版KSS评分中满意度分值显著高于内侧组“,”Objective:The X-ray was used to analyze the influence of the position of the femoral prosthesis and tibial prosthesis on the short-term clinical efficacy of the treatment of knee osteoarthritis during Unicompartmental knee arthroplasty. Methods:From December 2018 to April 2020, consecutively enrolled patients with clinical diagnosis of knee osteoarthritis in Shihezi City People\'\'s Hospital, and included patients who met the inclusion and exclusion criteria and who were eventually undergoing Unicompartmental knee arthroplasty The patients were continuously enrolled in this study, and the enrolled patients were subjected to imaging examinations at the 12th month after surgery. According to the relative position of the prosthesis, they were divided into medial group, central group, and lateral group. The clinical data, imaging data and 2011 version of KSS score were compared among the three groups. Results:At the 12th month after surgery, the satisfaction score of the 2011 version of the KSS score in the central group was significantly higher than that of the medial group and the lateral group, while the clinical symptom scores were lower; at the same time, the maximum knee flexion angle of the three groups was not obvious Difference, but the central group is slightly higher than the medial and lateral groups. Conclusion:The use of imaging examination to analyze the position of femoral prosthesis and tibial prosthesis is conducive to the clinical prediction of the best position of the prosthesis before Unicompartmental knee arthroplasty, and is of great value for improving clinical efficacy and patient satisfaction after surgery.
