摘要:

文题释义:
髋膝踝角:即髋关节中心、膝关节中心和踝关节中心形成的夹角,反映了下肢力线情况,与膝关节骨性关节炎进展之间存在一定的相关性。
内侧半月板后根撕裂:是一种骨性或软组织根性撕脱伤或放射状撕裂,通常位于内侧半月板后根附着点10 mm以内,这类损伤可分为急性损伤和退行性损伤。该文主要研究退行性内侧半月板后根撕裂在行半月板部分切除时,术前髋膝踝角是否会影响术后骨性关节炎的进展及术后临床疗效。

背景:半月板部分切除可有效减少退行性内侧半月板后根撕裂患者的机械症状,但其不能阻止膝关节骨性关节炎的进展,可能与下肢力线对预后的影响相关。
目的:探讨退行性内侧半月板后根撕裂患者行半月板部分切除后患侧膝关节骨关节炎进展与术前患侧膝关节髋膝踝角之间的相关性。
方法:回顾性分析中国人民解放军联勤保障部队第904医院2014年1至12月退行性内侧半月板后根撕裂行半月板部分切除治疗患者的病历资料,共纳入患者138例,平均随访(5.53±0.58)年。以术前患肢髋膝踝角的最佳截断值将患者分为A组(髋膝踝角>176.2°,n=77)和B组(髋膝踝角≤176.2°,n=61)。行ROC曲线分析术前患肢髋膝踝角对术后美国特种外科医院评分HSS的预测价值,采用Spearman相关性分析探究术前患肢髋膝踝角与术后最终HSS值的相关性,比较两组术后患膝内侧关节间隙宽度与凯格伦-劳伦斯分级情况。试验获得联勤保障部队第904医院伦理委员会批准,批准号:2018-10-002。
结果与结论:①ROC曲线显示,术前髋膝踝角对术后美国特种外科医院评分HSS具有一定的预测价值,曲线下面积为0.75;②单因素Logistics回归分析结果显示,术前髋膝踝角和术前病程是术后HSS评分的影响因素;多因素Logistics回归分析结果显示,术前髋膝踝角是HSS评分值的独立危险因素(P < 0.01),体质量指数和术前病程均不影响髋膝踝角与HSS评分值之间的相关性;③Spearman相关性分析结果显示,术前髋膝踝角与术后HSS评分呈正相关(r=0.472,P < 0.01),术前髋膝踝角越大,术后HSS评分越高、预后越好;④A组末次随访的关节间隙宽度大于B组(P < 0.01),凯格伦-劳伦斯分级程度低于B组(P < 0.05),说明A组的术后骨性关节炎进展慢于B组;⑤结果表明对于退行性内侧半月板后根撕裂患者,如果术前髋膝踝角≤176.2°则不适合进行半月板部分切除手术,如果术前髋膝踝角>176.2°可行半月板部分切除手术,但应该谨慎考虑相关危险因素。

Abstract: BACKGROUND: Partial meniscectomy can effectively reduce the mechanical symptoms of degenerative medial meniscus posterior root tear, but it cannot prevent the progression of knee osteoarthritis, which may be related to the effect of lower limb force line on prognosis. 
OBJECTIVE: To investigate the correlation between the progression of knee osteoarthritis and the hip-knee-ankle angle in patients with degenerative medial meniscus posterior root tears after partial meniscectomy.
METHODS: The medical records of 138 patients with degenerative medial meniscus posterior root tears treated by partial meniscectomy in 904 Hospital of the Joint Service Support Force of Chinese PLA from January to December 2014 were analyzed retrospectively. The average follow-up was (5.53±0.58) years. Patients were divided into group A (hip-knee-ankle angle > 176.2°, n=77) and group B (hip-knee-ankle angle ≤ 176.2°, n=61) according to the best truncation value of hip-knee-ankle angle before operation. Receiver operator characteristic (ROC) curve was used to analyze the predictive value of preoperative hip-knee-ankle angle to postoperative American special surgery hospital score HSS. Spearman correlation analysis was used to explore the correlation between preoperative hip-knee-ankle angle and postoperative final HSS value. The width of knee medial joint space and Kaglan-Lawrence classification were compared between the two groups. The trial was approved by the Ethics Committee of 904 Hospital of the Joint Service Support Force of Chinese PLA (approval No. 2018-10-002). 
RESULTS AND CONCLUSION: (1) The ROC curve showed that the preoperative hip-knee-ankle angle had a certain predictive value to the postoperative American special surgery hospital score HSS, and the area under the curve was 0.75. (2) Univariate Logistics regression analysis results showed that hip-knee-ankle angle and preoperative course of disease were influencing factors for postoperative HSS score. Multivariate Logistics regression analysis results showed that preoperative hip-knee-ankle angle was an independent risk factor for HSS score (P < 0.01), while body mass index and preoperative course of disease did not affect the correlation between hip-knee-ankle angle and HSS score. (3) Spearman correlation analysis results showed that the preoperative hip-knee-ankle angle was positively correlated with postoperative HSS score (r=0.472, P < 0.01). The greater the preoperative hip-knee-ankle angle and the higher the preoperative HSS score, the better the prognosis. (4) The width of postoperative joint space in group A was larger than that in group B (P < 0.01), and the degree of Kaglan-Lawrence grade in group A was lower than that in group B (P < 0.05), indicating progression of postoperative osteoarthritis in group A was slower than that in group B. (5) The results showed that for patients with degenerative medial meniscus posterior root tears, partial meniscectomy was not suitable if the hip-knee-ankle angle was ≤ 176.2°. Partial meniscectomy could be performed if the hip-knee-ankle angle was > 176.2°, but relevant risk factors should be carefully considered.
