Short-term clinical outcomes of primary rotating hinge knee arthroplasty for knees with severe deformity

Objective: To observe short-term outcome and complication of primary rotating hinge knee arthroplasty for knees with severe deformity. Methods A retrospective study from Oct 2005 to Oct 2010 was conducted on 30 patients after receiving the TKA using the Endo-Model rotating hinge prostheses. There were 13 males(13 knees),17 females(17 knees),with the mean age of(65.2?8.3)years(ranged 53-78 years). X-ray image, the Knee Society Score(KSS) and ROM and the flexion angle were used to evaluate postoperative outcome. The average ROM before operation is 57.4??15.6? Results The average follow-up time was 33 months. No complications of infection, thrombosis, vascular or nerval injury were obaserved. The ROM of knees were improved from average 57.4??15.6?to 95.3??10.2?The KSS clinical score and function score were improved from average 38.6?12.7 and 36.3?15.1 to 87.9?12.5 and 68.8?18.1, respectively。There were 9 patients having anterior knee pain and patellars shift or tilt in the axial view of X-ray was observed. Conclusion The short-term clinical outcomes of Endo-Model rotating hinge TKA are ideal, and it is a good choice for knees with severe deformity. However, the high rate of patellofemoral joint complications should be encountered.     

TKA术中自体骨移植联合螺钉固定重建内侧平台骨缺损

目的 探讨全膝关节置换(TKA)术中自体骨移植联合螺钉固定重建内侧平台骨缺损的疗效.方法 2001年11月至2004年11月,46例(50膝)伴内侧胫骨平台骨缺损患者行TKA手术,男16例(16膝),女30例(34)膝,骨性关节炎组(OA)35例(38膝),类风湿性关节炎组(RA)11例(12膝).46例患者术前常规采用三维CT重建估计胫骨平台截骨后骨缺损范围和深度,术中采用单块或内外髁双侧截骨块重叠填充骨缺损并采用空心钉固定.另随机抽取TKA患者80例(86膝)作为对照组.对手术情况、胫骨基座外移、关节线高度改变等比较分析,随访并记录KSS评分.结果 随访6～9年,46例患者中2例失访,1例术后5年死于心肌梗死,末次随访除深部感染1例外无假体松动发生;1例(1膝)楔形植骨术后8年出现骨质吸收,其余植骨块均愈合,无骨质吸收改变.OA组术中平台劈裂骨折3例(3膝),股骨远端截骨量、聚乙烯垫片厚度、胫骨假体型号、关节线抬高、胫骨基座外移均大于其他两组(q检验,P＜0.05).各组手术前后KSS评分差异均有统计学意义(F检验,P＜O.05),术后优于术前,同组术后6、9年比较差异无统计学意义(q检验,P＞0.05.结论 自体骨移植联合螺钉固定重建内侧平台骨缺损操作简单,能有效重建骨缺损、恢复关节稳定性,但OA硬化型骨缺损植骨时易出现胫骨假体外移、关节线抬高、术中胫骨劈裂骨折等并发症.

Abstract：

Objective To investigate the efficacy of autologous bone grafting plus screw fixation to reconstruct the medial tibial defects in total knee arthroplasty (TKA). Methods From November 2001 to November 2004, 46 patients (50 knees) with medial tibial bone defects underwent TKA at our hospital.There were 16 males (16 knees) and 30 females (34 knees). They included osteoarthritis (OA) (n = 35,38 knees) and rheumatoid arthritis (RA) (n = 11, 12 knees). A total of 46 patients underwent three-dimensional CT (computed tomography) reconstruction to evaluate the tibial plateau defects after osteotomy.Single or double distal femoral osteotomic bone was used to reconstruct the bone defects with the hollow nail internal fixation. Another 80 TKA patients (86 knees) were randomly selected as the control group. The surgical outcome, lateral migration of tibial component and joint line elevation, etc. were analyzed and the follow-up knee society scores recorded. Results The patients were followed up for 6 to 9 years. Two patients were lost to follow-up and 1 died of myocardial infarction at 5 years post-TKA in the test group. In the last follow-up, 1 case suffered deep infections and all others had no prosthetic loosening. One case ( 1 knee) had resorption of wedge-shaped bone graft after 8 years. The remaining graft healed and there was no screw displacement. Medial platform split fracture occurred in 3 patients (3 knees) in the OA group. The quantity of distal femoral osteotomy, thickness of polyethylene insert, tibial implant size, joint line elevation and lateral migration of tibial base were greater than the other two groups (q test, P ＜0. 05). The pre- and post-operative KSS scores had significant differences in each group ( F test, P ＜ 0. 05). But the same group showed no significant difference at 6, 9 years ( q test, P ＞ 0. 05). Conclusion As an easy and effective way of reconstructing the medial tibial bone defects, autologous bone grafting plus screw fixation can restore knee mechanical axis and stability. But in OA patients with tibial sclerosis, the complications of tibial component lateral migration, joint line elevation and splitting tibia fractures should be avoided during the reconstruction     

Comparison of total knee replacement with and without patella replacement

Objective To compare retrospectively the clinical outcome of total knee replacement with and without patellar replacement. Methods From January 1994 to December 2000, 109 knees in 86 patients treated for osteoarthritis and rheumatiod arthritis were evaluated postoperatively using a questionnaire and physical examination. There were 17 males and 69 females with the age ranging from 37 to 80 years( average 65.7 years). The osteoarthritis was 8 knees and rheumatoid arthritis 69 knees. Forty-two knees underwent patellar replacement, and 67 knees with reserved patella. The patients were scored using HSS Score for knees and Feller Score for patella. AP and lateral views of the knees as well as 30° and 90° axial views of patella were taken in radiography. The data were analyzed using SPSS software. Results Replacement and non-replacement groups showed no obvious difference in post-operative knee function and the incidence of complication. The two groups showed statistical significant differences in scoring o     

在人工全膝关节表面置换术中使用固定平台假体和旋转平台假体的效果对比

目的：对比分析在人工全膝关节表面置换术中使用固定平台假体和旋转平台假体的临床效果。方法：对2012年10月～2013年5月期间在我院进行人工全膝关节表面置换术的124例患者的临床资料进行回顾性研究。我们将这124例患者随机分为A组和B组,每组各有62例患者。我院给A组患者使用固定平台假体进行人工全膝关节表面置换术,给B组患者使用旋转平台假体进行人工全膝关节表面置换术。手术结束后,比较两组患者膝关节功能的KSS（世界膝关节学会）评分、HSS（美国膝关节学会）评分和膝关节的WOMAC（骨关节炎指数）评分以及发生并发症的情况。结果：在治疗前,两组患者膝关节功能的KSS评分、HSS评分和膝关节的WOMAC评分相比无显著性差异（P>0.05）。在治疗后,两组患者膝关节功能的KSS评分、HSS评分均较治疗前相比有明显的升高（P<0.05）,其膝关节的WOMAC评分较治疗前有明显的下降（P<0.05）。但两组患者治疗后膝关节功能的KSS评分、HSS评分和膝关节的WOMAC评分相比无显著性差异（P>0.05）。A组患者发生并发症的几率为9.68%,B组患者发生并发症的几率为6.45%。两组患者发生并发症的几率大体相当,二者相比差异无显著性（P>0.05）。结论：在人工全膝关节表面置换术中应用固定平台假体和旋转平台假体均可取得理想的效果。这两种假体无明显的优劣之分。临床医生应根据进行人工全膝关节表面置换术患者的具体情况为其选择假体的种类。

Long term follow up of clinical outcome between patellar resurfacing and nonresurfacing in total knee arthroplasty: Chinese experience

Background The long term outcome of patellar resurfacing in Chinese has not been well described.This study evaluated more than 10-year clinical outcomes and survivorship of patellar resurfacing or nonresurfacing in total knee arthroplasty.Methods From January 1993 to December 2002,265 patients accepted total knee arthroplasty in Department of Orthopaedic Surgery,Peking Union Medical College Hospital.Among them,226 patients （246 knees） were successfully followed up,with 176 knees for patellar resurfacing and 70 knees for nonresurfacing.The survivorship of total knee arthroplasty between two groups and the hospital for special surgery knee score （HSS）,patellar score,patellar related complication and radiological results were studied at the latest follow-up.Results The HSS knee score increased from 55.9±12.2 preoperatively to 92.0±10.9 postoperatively for patellar resurfacing group and from 56.6±9.9 to 94.2±11.4 for nonresurfacing group after average 11.4-year follow-up.Patellar score increased from 13.93±2.42 preoperatively to 28.33±2.20 for resurfacing group and from 13.55±2.73 to 27.8±2.37 for nonresurfacing group.There was no statistically significant difference for both HSS score,patellar score between the two groups with higher rate of anterior knee pain for nonresurfacing group.Patellar nonresurfacing had higher lateral subluxation than resurfacing group according to radiological evaluation.Patients with rheumatoid arthritis had 5.5 fold patellar related complication than patients with osteoarthritis.The 10-year survival rate was not statistically significant different between the two groups （P=0.12）.Conclusions There was no significant difference of long-term clinical outcome and survivorship between patellar resurfacing and nonresurfacing.Patellar nonresurfacing can be advisable during primary total knee arthroplasty especially in Chinese patients with osteoarthritis.Selective patellar resurfacing for patients with rheumatoid arthritis can achieve lower patella related complication.     

Unicompartment knee arthroplasty for knee joint disease

Objective To report the short-term result of unicompartmental knee arthroplasty ( UKA ) for osteoarthritis and spontaneous osteonecrosis of the knee, and discuss the indications and surgical pitfalls for the procedure as well. Methods From April 1999 to July 2000, unicompartmental knee arthroplasty were performed in 20 cases (24 knees). Osteoarthritis in 18 cases (20 knees) and spontaneous osteonecrosis in 2 cases (2 knees); 10 males (12 knees) and 10 females (12 knees). The range of motion (ROM), femorotibial angle (FTA) and JOA score were adopted as main parameters to evaluate the outcome of the operation. The mean age of the patients at the time of operation was 73. 3 ± 7. 1 years, and 75. 0 ± 6. 8 years at the final follow-up. The mean follow-up period was 25. 7 ± 15. 0 months. The prostheses used in the group were unicompartment sleigh shaped artificial joint of Link Endomodel Sled Knee, Waldemar Link or YCMK. Results Before operation, the mean ROM was from 5.4° ± 6.1° (extension) to 120.0°

Clinical Study on the Treatment of Knee Osteoarthritis of Shen(肾)-Sui(髓) Insufficiency Syndrome Type by Electroacupuncture

<正>Objective:To study the clinical efficacy of electroacupuncture(EA)on treating knee osteoarthritis (KOA)of Shen(肾)-Sui(髓)insufficiency(SSI)syndrome type.Methods:A total of 245 patients(279 knees)of KOA-SSI were randomly assigned to two groups by lottery:141 knees in the treatment group and 138 knees in the control group.The treatment group was managed with EA at the dominant points of Neixiyan(Ex-LE4) and Waixiyan(Ex-LE5)as well as the conjugate points of Xuanzhong(GB39)and Taixi(KI3)for 30 min,once a day,with 15 days as one course;2 courses were applied with a 5-day interval in between.The control group was treated with intra-articular injection of 2 mL hyaluronic acid into the affected joint every 7 days for 5 times in total.The clinical effects on the patients in different stages were observed,and their symptom scores of knee and contents of cytokines,including interleukin-1(IL-1),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α), prostaglandin E_(2α)(PGE_(2α)and matrix metalloproteinases-3(MMP-3),in the knee joint fluid were measured before and after treatment.Results:The study was completed in 235 patients(263 knees);four patients(7 knees) in the treatment group and six patients(9 knees)in the control group dropped out.Comparison of therapeutic effects(excellent and effective rates)between the two groups showed insignificant differences(P0.05). Symptom scores of knee and contents of cytokines in the knee fluid after treatment were lowered significantly in the patients of stageⅠ-Ⅲin both groups(P0.05 or P0.01).However,the lowering of the total symptom score of knee in the patients of stageⅢin the treatment group was more significant(P0.05).Conclusions:EA could effectively alleviate the clinical symptoms in KOA patients of stage 1,showing an effect superior to that of hyaluronic acid.EA also shows action in suppressing the secretion of IL-1,IL-6,TNF-α,PGE_(2α)and MMP-3 in the knee fluid.     

微创小切口技术在膝关节内侧胫股间室骨关节炎治疗中的应用

目的 了解微创小切口技术方法治疗膝关节内侧胫股间室骨关节炎的临床疗效.方法 自2007年10月至2010年6月,对22例(25膝)内侧胫股间室重度骨关节炎患者经关节镜探查后,采用微创小切口技术行sledge knee假体UKA手术,并与同期进行的19例(21膝)Gemini MKⅡ假体全膝关节置换术(TKA)治疗组相比较.结果 两组术前一般资料比较,差异均无统计学意义(均P＞0.05).与TKA组相比,UKA组的术中出血量更少[(148±26)ml比(278±36) ml],手术时间更短[(68±12) min比(86±12)min],而且患膝关节屈曲达90°的康复进程更快[(3.1±1.8)d比(9.1±2.2)d],首次下床的时间更早[(2.1±1.0)d比(3.8±1.0)d,(P＜ 0.05)].患者术后随访时间为6 ～ 34个月.末次随访时两组的KSS膝评分、KSS功能评分及WOMAC评分相比,差异均无统计学意义(均P ＞0.05).结论 与TKA治疗膝关节内侧胫股间室骨关节炎相比,关节镜技术与小切口UKA相结合的疗法组织创伤更小,关节功能康复更快;二者的中期临床疗效无明显差异.     

不置换髌骨的活动平台膝关节置换术后膝前痛的中期随访

目的 比较行固定平台和活动平台人工膝关节置换的患者术后的中期膝前痛情况。方法 选取2006至2009年于首都医科大学附属北京同仁医院骨科行固定平台和活动平台膝关节置换的患者作为研究对象,将其分为固定平台组和活动平台组。所有患者均未置换髌骨。记录患者术前术后膝前痛发生率、膝前痛评分、髌骨评分、KSS功能评分（Knee Society Function Score）,并进行术前术后和两组间的比较。拍摄术后膝关节正侧位和Merchant位X线片,观察髌骨位置情况。结果 共63人、85膝纳入研究。其中活动平台组31人、45膝,随访时间3.9~7.6年,平均（5.9±1.1）年。固定平台组30人、40膝,随访4.2~8.1年,平均（6.4±1.3）年。两组患者术后膝前痛评分、髌骨评分、KSS功能评分均较术前有明显提高,但两组患者间术后上述评分差异无统计学意义。两组患者间术后膝前痛发生率差异也无统计学意义。两组患者术后X-ray均未显示明显的髌骨脱位或半脱位。结论 非置换髌骨的活动平台和固定平台膝关节置换术均可以有效地缓解膝前痛、恢复膝关节功能,术后中期效果满意。相比固定平台假体,活动平台假体的应用并未显著地改善术后膝前痛情况。     

固定平台和活动平台在双侧膝关节置换术中的系统评价

目的应用Cochrane系统评价的方法评价在全膝关节置换术中选择固定平台或活动平台的疗效。方法检索并获取2000～2013年间发表的所有对同一患者行双侧膝关节置换术中比较选择固定平台和活动平台术后结果的随机对照试验,对其提取数据、评估偏倚风险及数据分析。结果共纳入7个随机对照试验。Meta分析显示,在再手术率膝评分、膝关节活动度、患者满意度、假体周围影的出现等几个指标中,两组结果无统计学差异。在膝功能评分这一指标上,尽管结果更有利于固定组（P〈0.000 1）,但在临床角度看来,该项差别无意义。结论在膝关节置换术中,使用固定平台或活动平台并无明显优劣,但仍需更多高质量随机对照试验来检验。
