微创切口与传统切口对全膝关节置换术后切口外侧皮肤感觉障碍影响的对比研究

目的：探讨微创切口与传统切口对全膝关节置换术（ TKA)后切口外侧皮肤感觉障碍面积大小及其转归的影响。方法前瞻性观察2011年7—12月拟行TKA患者术后切口外侧皮肤感觉障碍情况,按入院时间顺序前40膝纳入微创切口组,后80膝纳入传统切口组。微创切口组采用微创髌旁内侧切口,传统切口组采用传统膝前正中切口。记录患者术前相关信息,包括体质量、身高、年龄、性别、手术方式、膝关节美国纽约特种外科医院评分（ HSS评分)及膝关节活动度;术中患者止血带时间、手术切口长度、切口下极距胫骨结节上缘距离、切口上极距髌骨上缘距离。分别于术后6周、6个月、1年和2年对患者进行随访,测量患者切口外侧皮肤感觉障碍面积、HSS评分、膝关节活动度。对切口长度、切口位置与术后切口外侧皮肤感觉障碍面积及其转归进行相关分析。结果微创切口组有38例39膝,传统切口组有73例78膝完成随访,两组患者性别例数、患膝侧别、年龄、身高及体质量差异均无统计学意义（P值均>0．05)。患者术后均出现了切口外侧皮肤感觉障碍,但微创切口组患者的触觉和痛觉障碍面积在各随访时间点均小于传统切口组,差异均有统计学意义（P值均<0．01)。术后2年微创切口组有30膝切口外侧皮肤感觉功能得到完全恢复,传统切口组为23膝。两组感觉障碍面积与切口长度在术后6周、6个月、1年和2年时均具有明显的相关性,但这种相关性可随着时间的推移而逐渐变小。传统切口组感觉障碍面积与切口下极距胫骨结节上缘距离在术后6周、6个月、1年和2年时具有明显的相关性（P值均<0．05),与切口上极距髌骨上缘的距离在术后6周、6个月和1年时具有相关性（P值均<0．05)。 TKA术后患者的感觉障碍面积与止血带时间、HSS评分、膝关节活动度无相关性（P值均>0．05)。结论 TKA术中对膝前皮神经的切断可造成术后切口外侧皮肤感觉功能障碍,与传统切口相比,微创术后切口外侧皮肤感觉障碍的面积更小,恢复速度更快。     

可吸收胶原蛋白线与丝线编织非吸收线在口腔种植中的应用

背景：胶原蛋白线由动物的胶原蛋白制备而成,由于其具备可降解、无排异、易于制备、使用方便等优点,现在已开始大量使用于临床。 目的：比较胶原蛋白线与丝线编织线对口腔种植手术切口愈合的影响。 方法：100例种植手术患者随机等分为可吸收胶原蛋白线组和丝线编织非吸收性缝线组,分别使用2-0带圆针可吸收胶原蛋白缝合线与4-0带圆针丝线编织非吸收性缝线对伤口进行间断无张力缝合。植入后3,5,7 d观察缝线及伤口愈合情况,植入后第7天拆线,植入后14 d复诊。 结果与结论：可吸收胶原蛋白线组患者切口甲级愈合率明显多于丝线编织非吸收性缝线组(P < 0.05)。可吸收胶原蛋白线组患者口腔切口中的2-0带圆针可吸收胶原蛋白缝合线在治疗7 d时大多数被吸收,而丝线编织非吸收线组患者口腔切口中4-0带圆针丝线编织非吸收性缝线未见吸收。且使用2-0可吸收胶原蛋白线的患者口内缝线未见污物附着,线体清洁。而使用4-0丝线编织非吸收线缝合的患者口内可见线体周围有软垢附着。提示胶原蛋白线比丝线编织线更适合口腔种植手术切口的无张力缝合,能够获得更好的愈合效果,且时间能够与伤口愈合时间匹配,并能维持更好的口腔卫生。中国组织工程研究杂志出版内容重点：生物材料;骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性;组织工程全文链接：

外侧髌股关节退变对膝关节内侧单髁置换疗效的影响

目的外侧髌股关节退变被认为是膝内侧单髁置换术后预后不良的危险因素,本研究通过对因膝关节前内侧骨关节炎行Oxford单髁置换的中国病人前瞻性研究探讨这一结论的正确性。方法对本单位从2009年8月至2013年12月连续进行的126例(104位病人)单髁置换病例进行前瞻性数据收集,术前记录膝关节疼痛部位,并根据Ahlback系统分级记录放射学检查发现的髌股关节退变。术中观察股骨滑车软骨磨损情况,根据Weidow 5级分级系统记录磨损程度,同时记录磨损部位。术后1年随访用Hospital for Special Surgery膝关节评分系统和能否深蹲对临床疗效进行评定。根据术中观察的股骨滑车软骨磨损部位,将病人分为无磨损组(N组)、外侧磨损组(L组)和中内磨损组(M组),比较三组间术后疗效、满意度、术后并发症是否有差异。计量资料采用单因素的方差分析,计数资料采用的是卡方检验。结果共118膝(98病人)纳入统计分析。根据术中发现共81膝(68.6%)存在股骨滑车软骨面磨损,外侧磨损组(L组)11膝,中内侧磨损组(M组)70膝。三组病人术后1年HSS评分有显著提高,M组与N组相比,L组与N组相比提高均无明显差异,但L组提高程度轻度高于M组;术后能够自主行深蹲和起立动作共88例,其中N组28例,M组52例,L组8例,组间无统计学差异;术后轻度膝前痛9例,其中N组2例,L组1例,M组6例,组间无统计学差异。结论术前放射学发现的髌股关节退变和术中发现外侧髌股关节软骨磨损均不能作为Oxford内侧单髁置换的反指征。     

Mortality and perioperative complications after unicompartmental knee arthroplasty

Aim of studyUnicompartmental knee arthroplasty (UKA) has been increasingly utilized over the past decade secondary to favorable reports of better range of motion, higher activity levels, and increased patient satisfaction compared with total knee arthroplasty (TKA). The aim of this study was to determine the 90-day incidence of perioperative complications and mortality of patients undergoing UKA.MethodsOne thousand consecutive UKA in 828 patients were retrospectively reviewed. A retrospective review was performed to evaluate 90-day perioperative complication and mortality rates.ResultsThere were zero deaths during the study period. Twelve percent of surgeries were complicated by variances within the 90-day postoperative period. There was one deep venous thrombosis (0.1%) and no pulmonary emboli. Cardiovascular complications were infrequent. Three patients had a myocardial infarction (0.31%), one developed congestive heart failure (0.1%), one angina (0.1%), and three had arrhythmias (0.31%). Secondary procedures were performed in 15 patients during the follow-up period: seven were manipulations under anesthesia for arthrofibrosis, one was an arthroscopic removal of retained cement, one arthroscopic removal of a drain, one repeat wound closure after a dehiscence secondary to a fall, one open reduction internal fixation for a supracondylar femur fracture, three irrigation and debridement procedures for an aseptic hematoma, and one radical debridement with later successful conversion to a total knee arthroplasty for a periprosthetic infection.ConclusionThis study supports the notion that UKA is a safe procedure that is associated with a low rate of mortality and serious post-operative complications.Level of evidenceLevel IV, therapeutic study case series.     

CR假体与PS假体全膝关节置换治疗膝骨性关节炎合并膝外翻畸形的疗效分析

目的 比较后交叉韧带保留型（CR）假体与后方稳定型（PS）假体行人工全膝关节置换术（TKA）治疗膝骨性关节炎合并膝外翻畸形的临床疗效。方法 回顾性分析南昌大学附属赣州医院关节外科2019年5月至2021年5月收治的60例（60膝）膝骨性关节炎合并膝外翻畸形患者资料,均为单侧置换。30例采用CR假体行TKA治疗（CR组）,30例采用PS假体行TKA治疗（PS组）。比较两组患者的手术时间、术中失血量、术后引流量、术后3 d血红蛋白（Hb）下降量及深静脉血栓发生情况;比较两组患者手术前后膝外翻角;比较两组患者术后1周、1个月、3个月、6个月、1年疼痛视觉模拟评分（VAS）、膝关节活动度（ROM）、美国特种外科医院膝关节评分（HSS）。结果 60例患者均顺利完成TKA手术,所有患者随访13 ～ 28个月,平均（18.51±0.90）个月。CR组术中出血量、术后引流量、术后3 d的Hb下降量较PS组减少（P＜0.05）;两组手术时间相当、术后均无深静脉血栓发生,差异无统计学意义（P＞0.05）;两组手术前后膝外翻角的比较差异无统计学意义（P＞0.05）;CR组术后1周、1个月VAS评分较PS组更低（P＜0.05）,两组术后3个月、6月、1年VAS评分比较差异无统计学意义（P＞0.05）;CR组术后1周、1个月、3个月膝关节ROM和HSS评分优于PS组（P＜0.05）,两组术后6个月、1年膝关节ROM和HSS评分比较差异无统计学意义（P＞0.05）。结论 采用CR或PS假体行TKA手术治疗膝骨性关节炎合并膝外翻畸形均可有效纠正膝关节畸形、减轻膝关节疼痛、改善膝关节活动度及功能,取得满意临床疗效;但相对PS假体,CR假体保留了后交叉韧带,减少了股骨髁部截骨量,从而减少手术出血,更好减轻早期术后疼痛,有助于TKA术后早期功能康复。     

Salvage revision total knee replacement using the Endo-Model rotating hinge prosthesis

Inability to balance a knee in complex revision total knee replacement has led to the use of rotating hinged knee devices in these cases as a salvage procedure.

We conducted a retrospective study of 50 patients receiving 51 Endo-Model® rotating hinge prosthesis with an average follow-up of 4 years (range 2–6 years). Clinical and radiological results were reviewed at latest follow-up. Five patients died from unrelated causes. Reasons for revision were infection (23), aseptic loosening (23), implant failure (3), stiffness (1) and peri-prosthetic fracture (1). The average number of previous surgery from and including the primary arthroplasty was three (ranges 1–14). Seven patients required plastic surgery for soft tissue cover.

There was notable improvement in the pain, stability, range of motion and mobility of the patients with an improvement in the Hospital for Special Surgery Score (35.9 to 72.17). Postoperatively, 11 (22%) had an excellent HSS grade, 22 (44%) good grade, 10 (19%) fair grade and 8 (15%) poor grade. A significant number of our patients had an extremely low preoperative HSS score, and for these patients, an improvement to a fair grade HSS score was a satisfactory and realistic outcome. Forty-four (86%) patients were satisfied with the outcome of the revision surgery, 3 (6%) noncommittal and 4 (8%) disappointed. Comparing revision for infection vs. aseptic loosening, 22 (95%) patients out of 23 were satisfied in the aseptic loosening group vs. 17 (74%) out of 23 were satisfied in the infected group.

In selected complex cases, salvage revision surgery shows encouraging results in the short to medium term using the Endo-Model® rotating hinge prosthesis. A knee score such as the Hospital for Special Surgery score (objective outcome) should be used in conjunction with a patient satisfaction questionnaire (subjective outcome) in assessing the clinical outcome of complex, salvage revision knee surgery. Revision for infected total knee replacement is less likely to produce a satisfactory outcome as compared to revision for aseptic loosening.     

Outcome of total knee arthroplasty combined patelloplasty for end-stage type A hemophilic arthropathy

The aim of this study was to retrospectively evaluate the outcome of total knee arthroplasty for end-stage hemophilic arthropathy, based on effectiveness of operation, the specificity of surgical technique, the complications of TKA operation and the strategy of handling of patella. Nineteen patients (25 knees) with type A hemophilic arthropathy were treated with TKA from June 2003 to February 2010. Average patella thickness was 16.3±0.4mm and all patellas were treated by patelloplasty. The patient followed up data was recorded, which included the information of hospital for special surgery knee score(HSS), range of motion(ROM), post-operative complication, and anterior knee pain. The patients were followed for an average post-operative period of 41months (10 to 78months). The mean preoperative HSS score was 51 (31 to 64). Post-operative HSS score was 91 (75 to 110) when followed-up. ROM was modified to 82 degree (60 to 105), compared with 55 degree (5 to 110) preoperatively. Thirteen patients with flexion contracture were corrected from 19 degree (0 to 45) to 2.7 degree (0 to 10). Four patients complained mild but endurable anterior knee pain. The study concludes that TKA is an effective treatment for end-stage hemophilic arthropathy of knee joint, providing good clinical outcome and improving quality of life. Patella of hemophiliac is relatively thin and osteoporotic. Patelloplasty is useful technique for handling of patella during TKA procedure for hemophiliac, with improved knee function, low and acceptable anterior knee pain rate, low reoperation rate.     

Experience-optimised fast track improves outcomes and decreases complications in total knee arthroplasty

PurposeThe aim of this study was to describe an advanced total knee arthroplasty (TKA) fast-track programme and determine discharge parameters during hospitalisation, as well as patient satisfaction, outcomes and complications within the first 12 months after surgery.MethodsThis prospective study was based on patients selected consecutively for primary elective TKA, undergoing surgery between 2014 and 2017 in an established fast-track setting.Hospitalisation-related parameters were collected: demographics, body mass index (BMI), surgical time, ischaemia time, haemoglobin values, blood transfusions, length of stay, weight-bearing and stair-climbing time, opioid administration, preoperative and discharge loss of extension and maximum active flexion of the knee, visual analogue scale (VAS), 12-month follow-up satisfaction rate and range of motion, any complications, hospital re-admission and re-operation within the first 12 months. Differences were determined using t-tests.ResultsA total of 704 total knee replacements implanted in 481 patients were included in the study and 223 patients had a bilateral TKA. Their mean age was 69.8 years (range 57–88 years).At the 12-month follow-up, 623 patients (88.5%) reported being satisfied or very satisfied and 15 (2.1%) were dissatisfied with their TKA, mean active flexion and loss of extension were 104.4° and 2.3°, respectively. A total of 15 complications occurred (two percent): five painful knees, three knee stiffness, three haematomas, two infections, one hospital re-admission and one deep venous thrombosis. No cases of pulmonary embolism and death related to surgery were reported.ConclusionThe study reports on an advanced fast-track programme for TKA with a low incidence of surgery- and hospitalisation-related issues and complications and without any severe adverse events during the first year.On average, the fast-track programme had a short length of stay, an early recovery of weight-bearing, knee mobility, pain control and a high satisfaction rate, accompanied with an acceptable 12 month range of motion.

The Rotaglide mobile bearing knee arthroplasty A 10- to 13-year review from an independent centre

The Rotaglide knee arthroplasty has a highly congruent mobile meniscal bearing allowing both rotation and antero-posterior translation. We reviewed 137 consecutive primary arthroplasties in 120 patients at mean 11.1 years (10-12.9) following surgery. No cases were lost to follow-up. Hospital for Special Surgery (HSS) and American Knee Society (AKSS) scores were recorded at a review clinic. Radiographs were assessed using the Knee Society's roentgenographic evaluation system.Forty-two patients had died, leaving 78 patients (87 knees) available for review. Sixty-four patients (70 knees) were assessed at a clinic and in 14 (17 knees) clinical outcomes were obtained via telephone and their most recent radiographs were assessed. There were three cases of aseptic loosening and one deep infection requiring revision surgery. Two meniscal bearings were replaced with thicker inserts, one following bearing fracture and one following bearing dislocation. Survival at 11 years for aseptic loosening was 97.6% (95% CI 94.3 to 1.0) and survival using re-operation for any cause was 95.3% (95% CI 90.8 to 99.8).The Rotaglide mobile-bearing total knee replacement demonstrates good survivorship and outcome scores at 11 years following surgery.

探讨人工全膝关节置换术(TKA)结合加速康复外科(ERAS)理念治疗膝关节骨关节炎(KOA)的疗效。 方法选取赤峰市医院骨关节科2018年1月至11月收治的KOA患者220例,按随机数字表法分为2组,加速康复组(n＝108),遵循围手术期应用ERAS理念,严格执行加速康复程序;对照组(n＝112),沿袭传统手术管理模式。制定相同的出院标准,比较2组患者术后早期疼痛数字评分法(NRS)评分,术后输血率,恶心、呕吐发生率,口渴、饥饿发生率,达到出院标准的时间,术后2周的满意度评分,术后3个月美国特种外科医院(HSS)膝关节评分,术后并发症发生率等。数据比较采用t检验和χ²检验。 结果术后12、24、48 h,加速康复组术后早期疼痛NRS评分分别为(2.13±1.21)、(2.42±1.11)、(2.83±1.18)分,低于对照组[(3.24±1.45)、(3.35±1.23)、(3.78±1.25)分],差异均有统计学意义(t＝3.9498、3.7689、3.7088,P＝0.0002、0.0003、0.0004);加速康复组术后输血率6.5%(7/108),低于对照组[27.7%(31/112)],差异有统计学意义(χ²＝17.2887,P<0.05);加速康复组术后恶心、呕吐发生率为14.8%(16/108),低于对照组[38.4%(43/112)],差异有统计学意义(χ²＝15.5741,P<0.05);加速康复组术后口渴、饥饿发生率为12.0%(13/108),低于对照组[41.1%(46/112)],差异有统计学意义(χ²＝23.6163,P<0.05);加速康复组达到出院标准的时间平均为(2.9±1.3) d,少于对照组[(5.7±1.6) d],差异有统计学意义(t＝9.1301,P<0.05);加速康复组术后2周的满意度评分为(9.8±1.2)分,高于对照组[(8.9±1.1)分],差异有统计学意义(t＝3.7042,P<0.05);加速康复组、对照组术后3个月HSS膝关节评分分别为(88.2±13.2)、(87.7±16.6)分,2组比较差异无统计学意义(t＝0.1585,P＝0.8744);加速康复组并发症发生率为2.7%(3/108),低于对照组[9.8%(10/112)],差异有统计学意义(t＝4.5779,P＝0.0324)。 结论采用人工TKA结合ERAS理念治疗KOA,可以减轻术后应激反应,加速患者康复进程,减少手术并发症,缩短住院时间,提高患者满意度,是一种安全、可靠的选择,值得临床推广应用。
