全膝关节置换术（TKA）是目前治疗终末期膝关节疾病的首选方法,它能够缓解疼痛、改善畸形、恢复力线、增加膝关节活动度及提高患者生活质量。目前,关于胫骨假体旋转对线的方法很多,主要包括胫骨结节、胫骨前后轴、胫骨前皮质、自我形合技术、计算机辅助导航技术、个性化截骨技术等,它们各有优缺点,但在临床上并没有达成共识。该文主要对胫骨近端的解剖学特点和TKA中胫骨假体旋转定位的方法等方面进行综述。旨在为临床骨科医生在行TKA时,选择合适的胫骨假体旋转对线方法提供一些参考。

Total knee replacement（TKA） is currently the preferred treatment for end-stage knee disease,and it can relieve pain,improve deformity,restore strength lines,increase knee range of motion,and improve patients’ quality of life．At present,there are many methods for the rotation of alignment of tibial prosthesis,mainly including tibial tubercles,tibial anteroposterior axes,anterior tibial cortex,self-morphing technology,computer-aided navigation technology,personalized osteotomy technology,etc．Each of the methods above has its advantages and disadvantages,but there is no clinical consensus at present．This article mainly reviews the anatomical characteristics of the proximal tibia and the method of rotational positioning of tibial prosthesis in TKA,which aims to provide some reference for clinical orthopedic surgeons to select the appropriate tibial prosthesis rotation alignment method when performing TKA．

目的 探索在全膝关节置换(TKA)围手术期中实施以中医透药+整体针疗法为特色的中西医结合加速康复方案的可行性,考察中医、西医加速康复措施在单独应用和联合应用时的促康复效能。方法 以在我院行首次单侧全膝关节置换术的患者为研究对象。根据围手术期干预差异分为四组:A组12例,根据指南采取传统常规的围手术期处理;B组12例,在A组基础上,采取了西医加速康复措施;C组14例,在A组基础上,采取了中医透药+整体针疗法;D组15例,兼采用西医加速康复措施和中医透药+整体针疗法。统计所有患者术后24小时、术后3天视觉模拟疼痛评分(VAS)和术前、术后2周膝关节功能评分(HSS)。并作以上数据的组间比较。结果 四组患者术后24 h VAS组间差异无统计学意义,术后3 d VAS组间总体差异有统计学意义:组间两两比较,B、C、D组均低于A组(P<0.05),B、C、D组间差异则无统计学意义。四组患者术前HSS组间差异无统计学意义,术后2周HSS组间总体差异有统计学意义:组间两两比较,B、C、D组均高于A组(P<0.05),A、B、C组均低于D组(P<0.05),B、C组间差异无统计学意义。结论 中医透药+整体针疗法在TKA围术期应用切实可行,与加速康复理念有机结合可有效缓解患者围术期疼痛,改善术后膝关节功能。

Objective To explore the feasibility of implementing the accelerated rehabilitation program of integrated traditional Chinese and western medicine featuring TCM and holistic acupuncture in the perioperative period of total knee arthroplasty (TKA),and investigate the effectiveness of accelerated rehabilitation under concept of recovery after surgery ERAS of traditional Chinese medicine and western medicine in single application and joint application. Methods The patients who underwent the first unilateral total knee arthroplasty in our hospital were studied. According to the interventions during the perioperative period, they were divided into 4 groups: 12 cases in group A, which were treated according to the guidelines and traditional perioperative treatment; 12 cases in group B, on the basis of group A, western medicine accelerated rehabilitation measures were taken; for the 14 case in group C, on the basis of group A, TCM penetration combinate with holistic acupuncture therapy was adopted; in group D, the combination of western medicine accelerated rehabilitation measures and the TCM therapy above were implemented in 15 cases. The visual analogue score (VAS)of all patients at 24 hours and 3 days after surgery were counted, and their knee function scores in hospital for special surgery (HSS scores) were recorded before and 2 weeks after the surgery. Comparisons of the data above between different groups were carried out. Results There was no statistically significant difference between the 4 groups in the VAS at 24 h after the operation, but statistically significant difference was found in the comparison of VAS at the 3rd day after the operation;In pairwise comparison, the 3rd day's VAS of group B, C and D were all lower than that of group A (P<0.05). There was no statistically significant difference between the 4 groups in the HSS score before the operation, but statistically significant difference was found in the comparison of HSS score at the 2nd week after the operation;In pairwise comparison, the 2nd week's HSSscore of group B, C and D were all higher than group A (P<0.05),and that of group A,B and C were all lower than that of group D (P<0.05). Conclusion The application of TCM penetration medicine combinated with holistic acupuncture in perioperative period of TKA is practical and feasible. The combination of western medicine accelerated rehabilitation measures and the TCM therapy can effectively relieve patients' perioperative pain and improve postoperative knee function.

目的 探讨后稳定型全膝关节置换术患者术后股骨后髁偏距变化对早期功能的影响。方法 选取2013年1月—2016年1月我院收治的121例骨关节炎接受单侧后稳定型膝关节置换患者,记录所有患者术前与术后股骨后髁偏距,根据股骨后髁偏距变化情况分为A组(股骨后髁偏距不变或增加)与B组(股骨后髁偏距减小)。对两组患者进行至少12个月的随访,比较其骨关节炎指数评分(WOMAC)、美国膝关节协会评分(KS)、美国膝关节外科学会评分系统(HSS)及膝关节功能之间的差异。结果 术后,2组患者在前髁偏距变化、股骨假体屈曲角、胫骨后倾角、胫骨角方面差异无统计学意义(P＞0.05)。但术后1年A组患者在WOMAC评分、HSS评分和负重主动屈曲范围方面改善优于B组患者,差异有统计学意义(P＜0.05)。结论 重建股骨后髁偏距能够改善后稳定型全膝关节置换术患者术后早期的骨关节炎症状,并提升患者负重位主动屈曲范围,有一定临床价值。

Objective To explore the stabilized total knee arthroplasty effects on early functional changes of condylar offset. Methods 121 cases of posterior stabilized total knee arthroplasty in our hospital from Jan.2013 to Jan.2016 were enrolled in the study. All patients with preoperative and postoperative posterior condylar offset records, according to the changes of femoral condylar offset were divided into A group and B group. The patients in the two groups were followed for at least 12 months, and the differences in the Osteoarthritis Index score (WOMAC), the American Knee association score (KS), HSS score and knee function were compared. Results After surgery, two patients in the anterior condylar offset changes, femoral prosthesis flexion angle, tibial angle, tibial angle difference was not statistically significant (P > 0.05). But after 1 years, the improvement of WOMAC score, HSS score and weight-bearing active flexion range in group A was better than that in group B, the difference was statistically significant (P < 0.05). Conclusions The reconstruction of the posterior condylar offset can improve the stability after total knee arthroplasty in patients with early osteoarthritis symptoms, and enhance the active flexion range of patients with weight-bearing, which has some clinical value.

目的 通过比较利伐沙班、依若肝素和非抗凝治疗对全膝关节表面置换术后的疗效,分析全膝关节置换术后抗凝治疗的必要性、有效性及安全性。方法 选取2010年1月—2013年8月我科收治的全膝关节表面置换术的患者154例,按治疗方式分成利伐沙班组(A组)、依若肝素钠组(B组)及非抗凝组(C组)。观察各组术后静脉血栓栓塞发生率;术前及用药后凝血功能指标的变化;术后总失血量、显性失血量、隐性失血量;伤口情况;膝关节功能HSS评分。结果 A组与B组术后无静脉栓塞症发生,C组出现静脉栓塞症3例;A、B、C三组术前与术后凝血功能指标差异均无统计学意义(P>0.05);B组术后显性失血量高于A组(P<0.05);三组患者术前及术后各回访时间点膝关节功能HSS评分差异无统计学意义(P>0.05)。结论 抗凝药物预防全膝关节置换术后静脉血栓栓塞症的效果确切,利伐沙班与依若肝素疗效相当;抗凝治疗不会增加术后失血量及伤口并发症的发生率,且对术后膝关节中期功能恢复无影响。全膝关节表面置换术后使用抗凝治疗效果良好,安全性可。

Objective To compare the influence of anticoagulant therapy on the curative effect after total knee arthroplasty and evaluate the necessity, effectiveness and safety of anticoagulant therapy. Methods 154 patients after total knee arthroplastyfrom January 2010 to August 2013 in our department were divided into the rivaroxaban group (group A), the enoxaparin group (B group) and non anticoagulation group (group C) according to the treatments. It was observed that the postoperative venous thromboembolism incidence; changes of blood coagulation indexes before and after the operation; the total blood loss、dominant blood loss and hidden hemorrhage; the wound; the HSS score of knee function. Results None of postoperative venous thromboembolism occurred in group A and B, three cases of venous thromboembolism in group C;The differences of between preoperative and postoperative coagulation indexes in three groups had no statistical significance (P>0.05); Dominant blood loss in group B was significantly higher than that of group A (P<0.05); No statistical significance in the HSS scores of knee function of three group (P>0.05). Conclusion The effect of anticoagulant drugs on the prevention of venous thromboembolism after total knee arthroplasty is effective, same efficacy in the treatment with rivaroxaban or enoxaparin; anticoagulant therapy does not significantly increase the postoperative blood loss and the incidence of wound complications, does not influence the recovery of postoperative mid-term knee function. The use of anticoagulation therapy after total knee arthroplasty has good effect and be safety.
