摘要:

文题释义:
骨质疏松症:是最常见的骨骼疾病,是一种以骨量低、骨组织微结构损坏、导致骨脆性增加、易发生骨折为特征的全身性骨病。骨质疏松症可发生于任何年龄,但多见于绝经后女性和老年男性。
内侧开放楔形胫骨高位截骨术:是一种治疗内侧单间室膝骨关节炎的常用保膝手术,通过截骨矫形将下肢力线转移至外侧间室,从而减轻内侧间室压力,达到治疗目的。

背景:老年膝骨关节炎患者多伴有骨质疏松症,对于骨质疏松症是否会影响胫骨高位截骨治疗内侧间室膝骨关节炎的术后疗效,目前尚缺乏相关的临床研究。
目的:从影像学和患膝关节功能两方面探究骨质疏松症对内侧间室膝骨关节炎胫骨高位截骨后临床疗效的影响。
方法:回顾性分析2018年1月至2019年1月在北京中医药大学第三附属医院行胫骨高位截骨联合关节镜治疗的内侧间室膝骨关节炎患者63例的病历资料,根据骨密度测量结果分组:骨质疏松组(平均T值为-2.9 SD)30例,对照组(非骨质疏松组,平均T值为-0.9 SD)33例。术前及术后3,12,24个月采用疼痛目测类比评分评价膝关节疼痛情况;采用美国西安大略与麦克马斯特大学骨关节炎指数、Lysholm膝关节评分评价膝关节功能;术前及术中矫正后、术后24个月采用下肢力线比率评价下肢力线改变。
结果与结论:①所有患者均完成手术并获得随访;②两组的目测类比评分、美国西安大略与麦克马斯特大学骨关节炎指数以及Lysholm膝关节评分在术后随访均较术前显著改善(P < 0.05);两组的下肢力线比率在术中矫正后、术后24个月均较术前改善(P < 0.05);③术后3,12,24个月,两组间的目测类比评分、美国西安大略与麦克马斯特大学骨关节炎指数以及Lysholm膝关节评分相比差异均无显著性意义(P > 0.05);④术前、术中矫正后及术后24个月两组间的下肢力线比率相比差异无显著性意义(P > 0.05);⑤提示在胫骨高位截骨后的早中期,骨质疏松症对其术后疗效和下肢力线没有显著影响;由此可见胫骨高位截骨治疗骨质疏松性内侧间室膝骨关节炎的早中期疗效确切,能够明显缓解膝关节疼痛,改善膝关节功能,是治疗骨质疏松性内侧间室膝骨关节炎的良好选择;但骨质疏松是否会影响胫骨高位截骨后的远期疗效仍需要更多研究来证实。

Abstract: BACKGROUND: Elderly patients with knee osteoarthritis are mostly accompanied by osteoporosis. There is still a lack of relevant clinical studies on whether osteoporosis will affect the postoperative efficacy of high tibial osteotomy for medial compartment knee osteoarthritis.  
OBJECTIVE: To explore the effect of osteoporosis on the clinical efficacy of medial compartment knee osteoarthritis after high tibial osteotomy from the aspects of imaging and knee joint function.
METHODS:  A retrospective analysis was performed in 63 patients with medial compartment knee osteoarthritis who received high tibial osteotomy combined with arthroscopy in Third Affiliated Hospital of Beijing University of Chinese Medicine from January 2018 to January 2019. According to the results of bone mineral density measurement, there were 30 patients in the osteoporosis group (mean T value was  -2.9 SD). There were 33 patients in the control group (non-osteoporosis, mean T value was -0.9 SD). The knee joint pain was evaluated by visual analogue scale score before and 3, 12, and 24 months after operation. Knee function was evaluated by Western Ontario and McMaster University Osteoarthritis Index and Lysholm knee score. The ratio of lower limb force line was used to evaluate the change of lower limb force line before, after intraoperative correction and 24 months after surgery.  
RESULTS AND CONCLUSION: (1) All patients completed surgery and were followed up. (2) Visual analogue scale score, Western Ontario and McMaster University Osteoarthritis Index and Lysholm knee score in both groups improved over time after surgery compared with that before surgery (P < 0.05). The ratio of lower limb force line in both groups improved after intraoperative correction and 24 months after operation compared with that before operation (P < 0.05). (3) There was no difference in visual analogue scale scores, Western Ontario and McMaster University Osteoarthritis Index and Lysholm knee score between the two groups 3, 12 and 24 months after surgery (P > 0.05). (4) There was no significant difference in the ratio of lower limb force line between the two groups before surgery, after intraoperative correction and 24 months after surgery (P > 0.05). (5) It is indicated that in the early and middle stages of high tibial osteotomy, osteoporosis has no significant effect on the postoperative efficacy and lower limb force line. In conclusion, high tibial osteotomy has a definite curative effect in the early and middle stages of osteoporotic medial compartment knee osteoarthritis, which can significantly relieve knee pain and improve knee function, and is a good choice for the treatment of osteoporotic medial compartment knee osteoarthritis. However, more studies are needed to confirm whether osteoporosis will affect the long-term outcome after high tibial osteotomy.
