ObjectiveTo investigate the correlation of synovial fluid uric acid, the serum and synovial fluid interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α with knee osteoarthritis (KOA). MethodsThe clinical data of 130 patients with KOA treated between January and December 2013 and 30 patients with gouty arthritis (GA) treated at the same period were collected. The clinical symptoms, Western Ontario and McMaster Universities Osteoarthritis Index score, the serum and synovial fluid IL-1β, IL-6, and TNF-α, uric acid levels, radiographic joint stenosis score, and bone hyperplasia score of the patients were compared using t-test analysis and Spearman correlation analysis. ResultsIn the KOA group, the synovial fluid uric acid and joint stenosis score (r=0.31, P=0.037), bone hyperplasia score (r=0.38, P=0.027) were positively correlated; serum and synovial fluid uric acid gradient and hypnalgia were positively correlated (r=0.34, P=0.031); the synovial fluid IL-6 and joint stenosis score (r=0.33, P=0.029), bone hyperplasia score (r=0.37, P=0.032) were positively correlated; the synovial fluid IL-1β and joint stenosis score (r=0.39, P=0.023), bone hyperplasia score (r=0.34, P=0.034) were positively correlated; and the synovial fluid uric acid and IL-1β (r=0.26, P=0.003), IL-6 (r=0.21, P=0.016) were positively correlated. ConclusionSynovial uric acid, IL-1β and IL-6 play a role in the inflammatory progress of knee osteoarthritis.
Objective To observe the treatment efficacy and safety of glucosamine hydrochloride tablets on uremia patients with knee osteoarthritis (OA). Methods A total of 118 uremia patients with knee OA were selected and randomly divided into the glucosamine hydrochloride tablets treatment group (treatment group) and the coated aldehyde oxystarch capsules group (control group) with 59 cases in each group. The course was 8 weeks. The Lequesne Index was assessed for curative effect evaluation, and the change of blood indexes was observed to evaluate drug safety. Results The total effective rate of Lequesne Index in the treatment group was 72.9%, while that in the control group was 13.6%; the difference was statistically significant (χ2=42.303, P<0.001). There was no significant change in the two groups before and after treatment in terms of the patients’ dialysis adequacy, routine blood, blood electrolytes, liver and kidney function (P>0.05). Conclusion Glucosamine hydrochloride tablets is curative and safe in the treatment of uremia patients with OA.
ObjectivesTo systematically review the prevalence and disease burden of knee osteoarthritis (KOA) in China.MethodsPubMed, EMbase, CNKI, WanFang Data and VIP databases were searched to collect cross-sectional studies about the prevalence and disease burden of KOA in China from January 1st 1995 to August 31st 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using R statistical software.ResultsA total of thirty-three studies were included. The results of meta-analysis showed the prevalance rate of KOA was 18% (95%CI 14% to 22%), and it was higher in women (19%, 95%CI 16% to 23%) than in men (11%, 95%CI 9% to 13%) (P<0.05). The prevalence rates of KOA in different regions were as follows: 11% (95%CI 8% to 14%) in north, 17% (95%CI 15% to 20%) in north-east, 21% (95%CI 13% to 32%) in east, 21% (95%CI 13% to 33%) in north-west, 22% (95%CI 6% to 57%) in south-west, and 18% (95%CI 13% to 23%) in south-central, respectively.ConclusionsThe prevalence of KOA in China is high, and the disease burden is heavy. Due to the quantity and quality of included studies, more high-quality studies are required to verify the above conclusions in future.
Objective To observe and study the effect of neuromuscular exercise (NEMEX) on pain and physical function in patients with knee osteoarthritis (KOA). Methods From December 2016 to December 2017, a total of 70 participants with degenerative KOA were randomly divided into the control group and the observation group, with 35 participants in each group. The participants in the observation group received 8-weeks NEMEX, and the ones in the control group received 8-week quadriceps strengthening. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale and the WOMAC physical functional subscale were used to measure pain and physical function before treatment and after 1 week, 2 weeks, 4 weeks, and 8 weeks of treatment. Results The WOMAC pain scores of participants before treatment and after 1 week, 2 weeks, 4 weeks, and 8 weeks of treatment were 24.2±10.0, 23.4±9.1, 18.9±8.2, 15.0±6.3, 15.0±7.0, respectively in the observation group, and 25.6±9.8, 24.1±9.2, 20.2±8.8, 15.2±6.0, 11.4±5.3, respectively in the control group. After 1 week of treatment, neither group showed a significant change in pain than pretreatment (P>0.05), but after 2, 4, 8 weeks of treatment, both groups showed significant improvements in pain (P<0.05). There was no significant between-group difference in pain before treatment or after 1 week, 2 weeks, and 4 weeks of treatment (P>0.05), but after 8 weeks of treatment, statistically significant difference in WOMAC pain score was found between the two groups (t=2.439, P<0.05). The WOMAC physical function scores of participants before treatment and after 1 week, 2 weeks, 4 weeks, and 8 weeks of treatment were 94.3±31.0, 81.8±28.3, 68.9±22.1, 34.0±15.1, 22.0±8.0, respectively in the observation group, and 92.7±31.8, 82.6±29.3, 75.2±22.9, 52.2±20.0, 43.4±18.2 respectively in the control group. After 1 week, 2 weeks, 4 weeks and 8 weeks of treatment, both groups showed significant changes in WOMAC physical function scores than pretreatment (P<0.05). There was no statistically significant between-group difference before treatment or after 1, 2 weeks of treatment in physical function (P>0.05). The functional improvements in the observation group were significantly better than those in the control group after 4 and 8 weeks of treatment, and the differences were statistically significant (t=–4.287, –6.355; P<0.05). Conclusion NEMEX and quadriceps strengthening have similar effects in relieve pain in patients with KOA. And both exercises can effectively improve the physical function, and NEMEX is better than quadriceps strengthening on physical function improvement in patients with KOA.
ObjectiveTo explore the safety and effectiveness of Taylor spatial frame (TSF) in the treatment of medial compartmental osteoarthritis (MCOA) of the knee and the adjustment of the lower extremity force line at the same time.MethodsThe clinical data of 30 patients with MCOA who underwent high tibial osteotomy (HTO) between October 2016 and April 2017 were retrospectively analyzed. According to the different fixation methods, they were divided into external fixation group (TSF external fixation, 16 cases) and internal fixation group (locking steel plate internal fixation, 14 cases). There was no significant difference between the two groups in gender, age, side, disease duration, mechanical femur tibia angle (MFTA), and other general data (P>0.05). The operation time and intraoperative blood loss of the two groups were recorded and compared; MFTA was used to evaluate the recovery of the lower extremity force line at last follow-up; Hospital for Special Surgery (HSS) score was used to evaluate the clinical effecacy before operation and at 2 weeks, 1 month, and 3 months after operation.ResultsThe operation time and intraoperative blood loss of external fixation group were significantly less than those of internal fixation group (P<0.05). All patients were followed up 9-16 months, with an average of 12 months. There were 2 cases of delayed healing in the internal fixation group and 1 case of delayed healing in the external fixation group, and all healed after symptomatic treatment. All patients in the two groups had no complication such as needle infection, nonunion at osteotomy, osteomyelitis, and so on. At last follow-up, MFTA standard was used to evaluate the recovery of force line. The results of external fixation group were all excellent, while the results of internal fixation group were excellent in 10 cases and good in 4 cases. The difference between the two groups was significant (Z=–2.258, P=0.024). The HSS scores in the two groups were significantly improved at each time point after operation, and gradually improved with time after operation (P<0.05). The HSS score of the external fixation group was significantly higher than that of the internal fixation group (t=2.425, P=0.022) at 3 months after operation; and there was no significant difference between the two groups at other time points (P>0.05).ConclusionTSF has unique advantages in HTO treatment of MCOA patients and correction of lower extremity force line, such as shorter operation time, less bleeding, firm fixation, and less complications. It can accurately adjust the lower extremity force line after operation and has good effectiveness. It is an effective and safe fixation method.
ObjectivesTo systematically review the efficacy of unicompartmental knee arthroplasty on forgotten joint score (FJS) in patients with knee osteoarthritis.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on unicompartmental knee arthroplasty on FJS in patients with knee osteoarthritis from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 2 RCTs and 11 cohort studies were included. The results of meta-analysis based on RCTs showed that: compared to posterior stabilized total knee arthroplasty (PS-TKA), unicompartmental knee arthroplasty could improve FJS on 12-month (MD=9.23, 95%CI 0.53 to 17.93, P=0.04) after operation. The results of meta-analysis based on cohort studies showed that: compared to PS-TKA, unicompartmental knee arthroplasty could improve FJS on 6-week (MD=8.90, 95%CI 6.87 to 10.94, P<0.000 01), 6-month (MD=18.72, 95%CI 8.71 to 28.74, P=0.000 2), 1-year after operation (MD=13.41, 95%CI 8.87 to 17.95, P<0.000 01), and the last follow-up (MD=0.99, 95%CI 0.47 to 1.54, P=0.000 2).ConclusionsCurrent evidence shows that, comparing with PS-TKA, unicompartmental knee arthroplasty in knee osteoarthritis shows advantage in the improvement of FJS. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
