单髁置换术与全膝置换术治疗黄土高原地区大骨节病膝关节炎的疗效对比研究

目的 比较单髁置换术（UKA）与全膝置换术（TKA）治疗黄土高原地区大骨节病膝关节炎的疗效差 异。方法 选取2017年1月—2018年8月庆阳市人民医院收治的大骨节病膝关节炎患者40例作为研究对象。按手 术方式分成UKA组和TKA组，比较两组患者手术时间、术后引流量、膝关节活动度、HSS评分、血红蛋白质量 浓度、C反应蛋白等情况。结果 UKA组患者术前血红蛋白质量浓度、膝关节活动度、HSS评分、C反应蛋白与 TKA组患者比较，差异无统计学意义（P >0.05），具有可比性。UKA组患者手术时间短于TKA组患者（P <0.05）； 术后引流量少于TKA组患者（P <0.05）；UKA组患者的膝关节活动度大于TKA组患者（P <0.05）；UKA组患者 HSS评分高于TKA组患者（P <0.05）；UKA组患者血红蛋白质量浓度的下降程度低于TKA组患者（P <0.05）； UKA组患者C反应蛋白升高程度低于TKA组患者（P <0.05）。结论 UKA与TKA对大骨节病膝关节炎具有良好 的治疗效果，相比TKA，UKA优势明显，因此UKA更值得推广应用。

Effect of unicompartmental knee arthroplasty and total knee replacement on knee arthritis for patients with kashin-beck disease in loess plateau area

Objective To compare the therapeutic effect of unicompartmental knee arthroplastyt and total knee replacement on knee arthritis for patients with kashin-beck disease in loess plateau area. Methods A total of 40 patients with KBD knee joint arthritis of Kaschin-Beck disease who were admitted to the People''s Hospital of Qingyang City from January to September 2018 were selected as subjects. The patients were divided into the UKA group and the TKA group according to the operation method, and the two groups were compared in terms of intraoperative operation time, postoperative drainage volume, knee joint activity, HSS score, the amount of hemoglobin, the value of c-reactive protein, etc. Results Compared with preoperative hemoglobin, knee range of motion, HSS score and c-reactive protein, patients in the UKA group and the TKA group had similar conditions and were comparable (P > 0.05). Compared with the TKA group, the operative time and postoperative drainage were significantly lower in the UKA group than in the TKA group (P < 0.05). Compared with patients in the TKA group, patients in the UKA group had higher knee range of motion and HSS score than those in the TKA group (P < 0.05). Compared with patients in the TKA group, patients in the UKA group showed a significantly lower degree of hemoglobin decrease than those in the TKA group (P < 0.05). Compared with the postoperative c-reactive protein in the TKA group, the level of c-reactive protein in the UKA group was lower than that in the TKA group (P < 0.05). Conclusion Both unicompartmental knee arthroplasty and total knee replacement have good therapeutic effects on patients with KBD. But compared with total knee replacement, unicompartmental knee arthroplasty has obvious advantages in the treatment of KBD patients. Therefore, unicompartmental knee arthroplasty is more worthy of promotion and application in the treatment of KBD.
