Early Clinical and Functional Outcome of Primary Total Knee Replacement with Posterior Cruciate Substituting Prosthesis for Primary Knee Osteoarthritis Using 2011 Knee Society Score

Background: Primary knee Osteoarthritis (OA) is the commonest articular disease in middle age and elderly people. Primary total knee replacement (TKR) is a known world-wide standard and definitive treatment of primary knee OA following failed adequate non-operative management. It is of clinical importance to assess the clinical and functional outcome of TKR to prognosticate the severity of primary knee OA. The new (2011) knee society scoring system (nKSS) is both surgeons and patients’ assessment tool for the treatment outcome of TKR. Study Design: Prospective interventional analytical study. Aim and Objective: The aim of the study was to determine early clinical and functional outcome of primary total knee replacement in patients with primary knee osteoarthritis using nKSS. The objectives were: 1) To determine the pre-operative nKSS and post operative nKSS;2) To determine relationships between pre-operative nKSS and post operative nKSS at 6 weeks, 3, 6, 9 and 12 months;3) To determine the complication rates in patients undergoing primary TKR in the study centre. Methods: A prospective interventional study of 59 patients aged 51 to 70 years who had 67 Total Knee Replacements (TKRs) participated in the study between November 2015 to June 2018 at National Orthopaedics Hospital, Lagos, Nigeria. Patients’ sociodemographic data, pre-operative and post-operative nKSS system were recorded at 6 weeks, 3, 6, 9 and 12 months during follow up. The data were analyzed using Statistical Package for Social Science (SPSS). Results: There were 41 females and 18 males (M:F = 1:2.3). There were total of 67 TKRs with 31 right TKRs, 20 left TKRs and 8 staged bilateral TKRs. The participants’ age ranged from 51 to 70 years with the mean age of 59.5 (±8.5) years. Four patients did not complete the study due to various reasons. The remaining 55 participants completed the study period with progressive improvement of their post-operative nKSS at 6 weeks, 3, 6, 9 and 12 months post-operatively when compared with pre-operative nKSS (P value 0.5). Conclusion: This study revealed improved early clinical and functional outcome of primary total knee replacement in primary knee osteoarthritis using nKSS in all the studied patients. There is no significant negative effect of lower pre-operative nKSS (and its components) on the post-operative nKSS outcome.

Chondroitin sulfate and glucosamine combination in patients with knee and hip osteoarthritis:A long-term observational study in Russia

BACKGROUND Oral treatment of glucosamine(GA) combined with chondroitin sulfate(CS) was reportedly effective for pain relief and function improvement in osteoarthritis patients with moderate to severe knee pain in clinical trials. While the effectiveness of GA and CS on both clinical and radiological findings has been demonstrated, only a few high-quality trials exist. Therefore, controversy regarding their effectiveness in real-world clinical practice remains.AIM To investigate the impact of GA + CS on clinical outcomes of patients with knee and hip osteoarthritis in routine clinical practice.METHODS A multicenter prospective observational cohort study included 1102 patients of both genders with knee or hip osteoarthritis(Kellgren & Lawrence grades Ⅰ-Ⅲ) in 51 clinical centers in the Russian Federation from November 20, 2017, to March 20,2020, who had started to receive oral capsules of glucosamine hydrochloride 500 mg and CS 400mg according to the approved patient information leaflet starting from 3 capsules daily for 3 wk,followed by a reduced dosage of 2 capsules daily before study inclusion(minimal recommended treatment duration is 3-6 mo). Changes in subscale scores [Pain, Symptoms, Function, and Quality of Life(QOL)] of the Knee Injury and Osteoarthritis Outcome Score(KOOS)/Hip Disability and Osteoarthritis Outcome Score(HOOS) questionnaires during the observational period(up to 54-64wk with a total of 4 visits). Patients’ treatment satisfaction, data on the combined oral use of glucosamine hydrochloride and CS, concomitant use of non-steroidal anti-inflammatory drugs(NSAIDs), and adverse events(AEs) were also evaluated.RESULTS A total of 1102 patients with knee and hip osteoarthritis were included in the study. The mean patient age was 60.4 years, most patients were women(87.8%), and their average body mass index was 29.49 kg/m2. All subscale scores(Pain, Symptoms, Function, and QOL) of the KOOS and HOOS demonstrated clinically and statistically significant improvements. In patients with knee osteoarthritis, the mean score increases from baseline to the end of Week 64 were 22.87, 20.78,16.60, and 24.87 on Pain, Symptoms, Physical Function(KOOS-PS), and QOL subscales(P < 0.001for all), respectively. In patients with hip osteoarthritis, the mean score increases were 22.81, 19.93,18.77, and 22.71 on Pain, Symptoms, Physical Function(HOOS-PS), and QOL subscales(P < 0.001for all), respectively. The number of patients using any NSAIDs decreased from 43.1% to 13.5%(P < 0.001) at the end of the observation period. Treatment-related AEs occurred in 2.8% of the patients and mainly included gastrointestinal disorders [25 AEs in 24(2.2%) patients]. Most patients(78.1%) were satisfied with the treatment.CONCLUSION Long-term oral GA + CS was associated with decreased pain, reduced concomitant NSAID therapy, improved joint function and QOL in patients with knee and hip osteoarthritis in routine clinical practice.

Establishing minimum clinically important difference values for the Patient-Reported Outcomes Measurement Information System Physical Function, hip disability and osteoarthritis outcome score for joint reconstruction, and knee injury and osteoarthritis out

AIM To establish minimum clinically important difference(MCID) for measurements in an orthopaedic patient population with joint disorders.METHODS Adult patients aged 18 years and older seeking care for joint conditions at an orthopaedic clinic took the Patient-Reported Outcomes Measurement Information System Physical Function(PROMIS~? PF) computerized adaptive test(CAT), hip disability and osteoarthritis outcome score for joint reconstruction(HOOS JR), and the knee injury and osteoarthritis outcome score for joint reconstruction(KOOS JR) from February 2014 to April 2017. MCIDs were calculated using anchorbased and distribution-based methods. Patient reports of meaningful change in function since their first clinic encounter were used as an anchor.RESULTS There were 2226 patients who participated with a mean age of 61.16(SD = 12.84) years, 41.6% male, and 89.7% Caucasian. Mean change ranged from 7.29 to 8.41 for the PROMIS~? PF CAT, from 14.81 to 19.68 for the HOOS JR, and from 14.51 to 18.85 for the KOOS JR. ROC cut-offs ranged from 1.97-8.18 for the PF CAT, 6.33-43.36 for the HOOS JR, and 2.21-8.16 for the KOOS JR. Distribution-based methods estimated MCID values ranging from 2.45 to 21.55 for the PROMIS~? PF CAT; from 3.90 to 43.61 for the HOOS JR, and from 3.98 to 40.67 for the KOOS JR. The median MCID value in the range was similar to the mean change score for each measure and was 7.9 for the PF CAT, 18.0 for the HOOS JR, and 15.1 for the KOOS JR.CONCLUSION This is the first comprehensive study providing a wide range of MCIDs for the PROMIS? PF, HOOS JR, and KOOS JR in orthopaedic patients with joint ailments.

Mid-term Outcomes of Primary Constrained Condylar Knee Arthroplasty for Severe Knee Deformity

This study aimed to examine the clinical and radiographic outcomes of primary total knee arthroplasy（TKA） with use of Nex Gen#174; Legacy#174; Constrained Condylar Knee（CCK） prosthesis for severe knee deformity. Clinical data of 46 patients（48 knees in total, aged 61 years on average） with severe knee deformity who underwent TKA with Nex Gen#174; Legacy#174; CCK prosthesis between December 2007 and February 2012 were retrospectively analyzed. There were 34 knees with severe valgus with incompetent medial collateral ligament, 11 knees with severe flexion contracture with inability to achieve knee balancing in flexion and extension by posterior soft tissue release, 2 knees with Charcot arthritis with severe varus and bone loss, and 1 with traumatic osteoarthritis with severe varus and ligamentous instability. The mean duration of follow-up was 71 months（range 40–90 months）. The New Knee Society scoring（NKSS） system and the Hospital for Special Surgery（HSS） score were used to evaluate the functional and clinical outcomes. Visual Analogue Scale（VAS） was used for pain measurement and Knee Society criteria for evaluation of radiological images. The results showed that, in the total 48 knees, 1 case of loosening due to short-stem tibial component at 3 months post-operatively underwent revision. The 6-year prosthesis survival rate in this cohort was 97.9%. There was no component infection occurring within 6 years. Significant post-operative improvements were found in NKSS and HSS scores. Patient satisfaction was significantly increased. Pain score was decreased significantly. Total functional score was improved from 31.46±11.43 to 86.42±8.87, range of motion（ROM） from 42.42°±23.57° to 95.31°±23.45° and the flexion contracture from 5.31°±7.87° to 0.92°±1.80°. Preoperative radiographic study showed excessive valgus（≥7°） in 37 knees, and varus deformity in 3 knees. Post-operative femorotibial alignment was valgus 3.88°±1.76° in 48 knees. Antero/posterior（A/P） view of X-ray films showed 4 radiolucent lines（RLL） in 48 tibial components. It was concluded that TKA with CCK is effective for the treatment of the severe unstable knee that cannot be balanced by soft tissue.

Impact of medial open-wedge high tibial osteotomy for medial compartment osteoarthritis of the knee

BACKGROUND Most populations worldwide,who are used to squatting and sitting cross-legged for their activities of daily living,largely comprise the lower socioeconomic strata,thus making them candidates for exclusion for total knee arthroplasty.Proximal/high tibial osteotomy(HTO)is a preferred strategy for clinically symptomatic osteoarthritis(OA)with genu varum due to painful medial compartment OA which is not amenable to conservative measures.AIM To evaluate the outcomes of medial open-wedge HTO along with autologous bone grafting and buttress plate for the treatment of genu varum due to OA of the knee in a rural population of central India.METHODS A total of 65 knees in 56 patients with a mean age of 58.22±5.63 years with genu varum due to intractable painful knee OA were treated with medial open-wedge HTO along with autologous bone grafting and buttress plate osteosynthesis from June 2015 to May 2018.The mean preoperative radiological angle of genu varum was 13.4°.Clinical outcomes were assessed by the range of movement,knee scores,pain scores,and functional scores.Radiographic studies were performed preoperatively and at regular intervals during the follow-up period.RESULTS All patients reported pain relief immediately after the osteotomy and during the long-term analysis covering between one to three years.The genu varum angle was overcorrected to approximately four degrees in all patients.There was a loss of reduction by approximately three degrees in all patients at around six weeks postoperatively.Preoperative knee movements were restored in all patients.No major perioperative complications were noted during surgery and postoperative follow-up and the clinical scores were significantly improved during the final analysis which revealed good pain relief.CONCLUSION Medial open-wedge HTO is a reliable,safe,practical,physiological,and feasible treatment for populations who are used to increased activity in their occupation and lifestyle and is associated with excellent short-term and long-term results for OA in genu varum knees.

Experiences in total knee arthtroplasty after distal femoral varus osteotomy

Introduction: There is only little information available about total knee arthroplasty (TKA) following distal femoral varus osteotomy (DFVO). The aim of our study was to show our experiences and mid-term results of TKA after a previous DFVO. Material and method: In a retrospective study we identified 36 consecutive patients who had undergone TKA after a previous distal femoral varus osteotomy. The average duration of follow-up after the TKA was 8.2 years (min: 5.0, max: 9.2). X-rays were taken in 2 planes before TKA, 1 week after TKA and at latest follow-up. Tibiofemoral alignment was measured on weightbearing long-leg anteroposterior radiographs. Ra- diolucent lines at latest follow-up were documented. Functional evaluations were performed preoperatively and postoperatively (at the time of latest follow-up). Results: The mean Knee Society knee score in- creased from 42 points before the arthroplasty to 91.3 points after the arthroplasty. The mean Knee Society function score increased from 27.4 points preoperatively to 93.2 points postoperatively. The mean overall Knee Society score increased from 91.3 points preoperatively to 163.4 points postoperatively. The mean radiographic alignment was 4.5? of valgus (10? of varus to 19? of valgus) before TKA and 3.1? of valgus (range, 3? of varus to 6? of valgus) at the time of latest follow-up. Postoperative complications included one deep vein thrombosis with non-lethal pulmonary embolism, one wound infection requiring revision and one septic loosening. Discussion: It is possible to perform TKA following DFVO with good mid-term results. In comparison to the literature there is no higher risk of complications in TKA following DFVO in comparison to primary TKA.

目的 探讨筋骨并重平衡法治疗膝关节退行性骨关节炎的临床效果。方法 选取2019年1月至2022年10月靖江市中医院住院的72例膝关节退行性骨关节炎患者作为研究对象,按照随机数字表法将患者分为治疗组和对照组,每组各36例。对照组采用常规药物治疗,治疗组在对照组基础上给予筋骨并重平衡法。比较两组患者的视觉模拟评分法(VAS)及西大略和麦克马斯特大学(WOMAC)膝关节评分。结果 治疗前,两组患者的VAS评分、WOMAC膝关节评分比较,差异无统计学意义(P>0.05)。治疗组治疗后的VAS评分、WOMAC膝关节评分低于治疗组,差异有统计学意义(P<0.05)。结论 筋骨并重平衡法治疗膝关节退行性关节炎相较单纯使用玻璃酸钠关节腔注射及塞来昔布口服疗法更为有效。

Knee awareness and functionality after simultaneous bilateral vs unilateral total knee arthroplasty

AIM: To investigate knee awareness and functional outcomes in patients treated with simultaneous bilateral vs unilateral total knee arthroplasty(TKA).METHODS: Through a database search, we identified 210 patients who had undergone unilateral TKA(UTKA) and 65 patients who had undergone simultaneous bilateral TKA(SBTKA) at our institution between 2010 and 2012. All TKAs were cemented and cruciate retaining. The mean follow-up period was 3.2(2 to 4) years. All the patients had symptomatic and debilitating unilateral or bilateral osteoarthritis for which all conservative and non-surgical treatments were failed, thus preoperatively the patients had poor functionality. All patients were asked to complete Forgotten Joint Score(FJS) and Oxford Knee Score(OKS) questionnaires. The patients were matched according to age, gender, year of surgery, Kellgren-Lawrence score and pre- andpostoperative overall knee alignment. The FJS and OKS questionnaire results of the two groups were then compared. RESULTS: A mixed-effects model was used to analyze differences between SBTKA and UTKA. OKS: The mean difference in the OKS between the patients who had undergone SBTKA and those who had undergone UTKA was 1.5, which was not statistically significant(CI =-0.9:4.0, P-value = 0.228). The mean OKS of the SBTKA patients was 37.6(SD = 9.0), and the mean OKS of the UTKA patients was 36.1(SD = 9.9). FJS: The mean difference in the FJS between the patients who had undergone SBTKA and those who had undergone UTKA was 2.3, which was not statistically significant(CI =-6.2:10.8, P-value = 0.593). The mean FJS of the SBTKA patients was 59.9(SD = 27.5), and the mean FJS of the UTKA patients was 57.5(SD = 28.8). CONCLUSION: SBTKA and UTKA patients exhibited similar joint functionality and knee awareness. Our results support the use of SBTKA in selected patients suffering from clinically symptomatic bilateral osteoarthritis.

超声介入精准治疗对膝关节退行性骨关节病的应用效果观察

目的:探讨对膝关节退行性骨关节病患者采取超声介入精准治疗的临床效果。方法:选取2020年2月—2022年2月内蒙古包钢医院收治的膝关节退行性骨关节病患者78例作为研究对象,采用抽签法分为观察组与对照组,各39例。对照组应用针刺治疗,观察组应用超声介入精准治疗。比较两组治疗效果、疼痛程度、骨关节炎指数及生活质量。结果:观察组治疗总有效率高于对照组,差异有统计学意义(P=0.012)。治疗前,两组疼痛视觉模拟评分法(VAS)比较,差异无统计学意义(P>0.05);治疗后,观察组VAS评分低于对照组,差异有统计学意义(P<0.001)。治疗前,两组膝关节炎指数(WOMAC)评分比较,差异无统计学意义(P>0.05);治疗后,观察组WOMAC评分低于对照组,差异有统计学意义(P<0.001)。治疗前,两组健康状况调查问卷(SF-36)各项评分比较,差异无统计学意义(P>0.05);治疗后,观察组SF-36各项评分高于对照组,差异有统计学意义(P<0.001)。结论:膝关节退行性骨关节病患者采取超声介入精准治疗,可提高治疗效果,缓解患者疼痛程度,改善骨关节功能及生活质量。

膝骨关节炎患者骨髓水肿MRI特征及其与VAS评分的相关性

目的分析膝骨关节炎患者骨髓水肿的MRI特征,并探讨其与视觉模拟评分量表(VAS)评分的关系。方法回顾性分析2021年2月至2022年5月期间于延安市人民医院诊治的85例膝骨关节炎患者的病历资料,根据患者膝关节MRI检查中的骨髓征象分组,其中21例骨髓水肿征象评估为0级者纳入对照组,32例骨髓水肿征象评估为1级者纳入Ⅰ组,32例骨髓水肿征象评估为3级者纳入Ⅱ组。比较三组患者的VAS评分,并采用Spearman相关性分析骨髓水肿MRI特征与VAS评分相关性。结果Ⅰ组、Ⅱ组和对照组患者的VAS评分分别为(5.46±1.03)分、(7.21±1.27)分、(4.13±1.18)分,其中Ⅱ组患者的VAS评分明显高于Ⅰ组和对照组,Ⅰ组明显高于对照组,差异均统计学意义(P<0.05);经Spearman相关性分析结果显示,骨髓水肿征象等级与VAS评分呈正相关(P<0.05)。结论股骨关节炎患者经MRI检查图像评估的骨髓水肿征象等级与VAS评分存在相关性,患者骨髓水肿征象等级越高,VAS评分也越高。
