Objective To investigate the effect of knee suspension during titanium plate fixation on postoperative posterior tibial slope (PTS) in knee osteoarthritis (KOA) with medial opening-wedge high tibial osteotomy (OWHTO). Methods The clinical data of 47 patients with KOA treated by OWHTO between January 2019 and December 2020 was retrospectively analyzed. In 24 cases, the knee joint was suspended when titanium plate was fixed (research group), and in 23 cases, the knee joint was naturally straightened when titanium plate was fixed (control group). There was no significant difference in gender, age, side, body mass index, disease duration, preoperative visual analogue scale (VAS) score, American Hospital for Special Surgery (HSS) score, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score, Lysholm score, and preoperative PTS between the two groups (P>0.05). PTS were measured at 1 day after operation and last follow-up, and were compared with that before operation. Before operation and at last follow-up, VAS score was used to evaluate the knee pain, HSS score, WOMAC score, and Lysholm score were used to evaluate the knee function. Results The patients in both groups were followed up 13-24 months, with an average of 19.9 months. There was no complication such as incision infection, screw fracture, and deep venous thrombosis of lower limbs in two groups. At last follow-up, the VAS score, HSS score, WOMAC score, and Lysholm score in two groups were significantly improved when compared with those before operation (P<0.05), but there was no significant difference between the two groups in the each score difference of before and after operation (P>0.05). There was no significant difference in PTS at each time point before and after operation in the research group (P>0.05), but PTS in the control group significantly increased at 1 day after operation and last follow-up (P<0.05). PTS of the research group at 1 day after operation and last follow-up were significantly lower than those of the control group (P<0.05). ConclusionOWHTO can effectively relieve knee pain and improve knee function in KOA, and the increase of postoperative PTS can be effectively avoided by suspending knee joint.
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.
Objective To explore the effect of internet of things-based power bicycle training or quadriceps training alone on pain and quality of life in patients with knee osteoarthritis in a community setting. Methods Patients with knee osteoarthritis who were admitted to West China Hospital of Sichuan University between April and July 2022 were selected. They were randomly divided into a power bicycle training group, a quadriceps muscle training group and a control group by random number table method. The primary outcome was improvement in knee pain, assessed by the Numerical Rating Scale (NRS) score. The secondary outcome was health-related quality of life, assessed by the 36-Item Short Form Health Survey (SF-36) score. Outcomes were assessed at baseline and 4, 8, and 12 weeks after the initial intervention. The statistical analysis was conducted using generalized estimating equations. Results A total of 72 patients were included, with 24 in each group. There was no significant difference in age, gender or other demographic characteristics among the three groups (P>0.05). The results of generalized estimating equations showed that there were interaction effects (group × time) on the NRS score, SF-36 physical functioning score, SF-36 bodily pain score, and SF-36 vitality score (P<0.05), while there was no interaction effect (group × time) on the role physical score, general health score, social functioning score, role emotional score or mental health score of SF-36 (P>0.05). At baseline, there was no statistically significant difference in the NRS score or SF-36 scores among the three groups (P>0.05). After 12 weeks of intervention, the two training groups were better than the control group in the NRS score, SF-36 physical functioning score, and SF-36 bodily pain score, the power bicycle training group was better than the quadriceps training group in the NRS score, the power bicycle training group was better than the control group in the SF-36 social functioning score, and the differences were statistically significant (P<0.05). Conclusions In a community setting, 12 weeks of internet of things-based power bicycle training and quadriceps training can significantly improve joint pain, physiological function and physical pain indicators in patients with knee osteoarthritis, and the power bicycle training is better than the quadriceps training in improving the knee pain of patients.
ObjectiveTo systematically review the efficacy of moxibustion in the treatment of model rabbits with knee osteoarthritis (KOA).MethodsCNKI, WanFang Data, VIP, CBM, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect animal experiments on moxibustion in the treatment of model rabbits with KOA from inception to January 31st, 2019. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 13 articles involving 226 model rabbits were included. The results of meta-analysis showed that moxibustion could reduce Mankin score (MD=?6.47, 95%CI ?7.63 to ?5.32, P<0.000 01), positive expression rate of chondrocyte apoptosis (MD=?22.21, 95%CI ?23.22 to ?21.21, P<0.000 01), level of IL-1β in joint fluid (SMD=?8.40, 95%CI ?15.09 to ?1.72, P=0.01), NO content in joint fluid (SMD=?11.03, 95%CI ?17.87 to ?4.19, P=0.002), the level of serum IL-1β (MD=?19.94, 95%CI ?23.61 to ?16.27, P<0.05), and serum NO content (MD=?22.69, 95%CI ?28.77 to ?16.61, P<0.05) of model rabbits with KOA.ConclusionsCurrent evidence shows that moxibustion can improve articular cartilage injury, strengthen chondrocyte activity, inhibit the inflammatory response, and inhibit chondrocyte apoptosis of model rabbits with KOA. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
【Abstract】 Objective To evaluate the results of glucosamine hydrochloride in the treatment of knee degenerativeosteoarthritis (DOA) . Methods From February 2006 to January 2007, 60 patients with knee DOA were treated with glucosaminehydrochloride,including 15 males and 45 females. The ages of patients ranged from 41 to 67 years with an average ageof 57.5 years. The disease course ranged from 6 months to 3 years. Oral glucosamine hydrochloride was given twice a day, each750 mg, for a 6-week course of treatment; another course of treatment was repeated after 4 months. After two courses of treatment,the international standard DOA score of Lequesne index was used to evaluate the rest of knee pain, sports pain, tenderness,joints activity, morning stiffness and walking abil ity. Results All 60 patients finished treatment, various cl inical symptomsfor DOA disappeared completely in 31 cases and subsided in 27 cases; the cure rate was 51.7% and the total response rate was96.7%. The scores of rest pain, sport pain, tenderness, joints activity, morning stiffness and the abil ity to walk for knee after treatmentwere 0.5±0.2,0.7±0.4,0.8±0.3,0.9±0.4,0.6±0.3 and 0.9±0.4, showing statistically significant differences (P lt; 0.01) whencompared with preoperation (1.6±0.5,2.1±0.4,2.2±0.5,1.8±0.6,1.7±0.4 and 2.0±0.4). Adverse effect occurred in 3 cases (5%)and the patients recovered without special treatment. Conclusion Glucosamine hydrochloride can cure knee DOA withsymptom-rel ieving and joint function-improving action.
Objective To observe the treatment efficacy and safety of glucosamine hydrochloride tablets on uremia patients with knee osteoarthritis (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 study the effect of multi-disciplinary treatment (MDT) on the surgical efficacy and satisfaction of patients undergoing total knee arthroplasty (TKA) for the first time. Methods The clinical data of patients who underwent unilateral TKA for single-compartment osteoarthritis of the knee in the General Hospital of Ningxia Medical University between January and September 2022 were retrospectively collected and analyzed. According to whether MDT was performed on patients during the perioperative period, they were divided into MDT group and traditional group. Perioperative nutrition-related indicators, perioperative complications, total hospitalization time, Visual Analogue Scale (VAS), and Hospital for Special Surgery Knee Score (HSS) before and after surgery were detected and recorded. Results A total of 95 patients were included. Among them, there were 42 cases in the MDT group and 53 cases in the traditional group. The postoperative complications and total hospital stay of patients in the MDT group were lower than those in the traditional group, and their satisfaction scores were higher than those in the traditional group (P<0.05). The perioperative serum total protein (TP), hemoglobin (Hb), serum albumin (ALB) levels, VAS score, and HSS score of both groups of patients changed over time. The intra group comparison results showed that compared with preoperative, the levels of TP, Hb, and ALB in both groups decreased on the 1st and 3rd postoperative days (P<0.05). On the 3rd day after surgery, the levels of TP, Hb, ALB in the MDT group and Hb, ALB in the traditional group were lower than on the 1st day after surgery (P<0.05). There was no statistically significant difference in TP levels between the traditional group on the 3rd day after surgery and the 1st day after surgery (P>0.05). The results of intra group comparison at different time points showed that there were statistically significant differences in VAS score and HSS score between the two groups (P<0.05). Conclusion The application of MDT in elderly patients undergoing unilateral TKA for the first time can shorten the total hospitalization time, reduce the incidence of perioperative complications, and improve the surgical efficacy and patient satisfaction.
Objective To explore the effects of intra-articular injection of platelet-rich plasma (PRP) on improving pain, joint function, and muscle strength of knee osteoarthritis (KOA). Methods From March 2017 to August 2019, 100 cases of KOA diagnosed and treated in the First Affiliated Hospital of Harbin Medical University were selected. They were divided into intervention group and control group with 50 cases in each group by random number table method. The patients in the intervention group were given intra-articular injection of PRP (5 mL/time, 1 time/week, 6 times in total) combined with isokinetic strength training (2 times/d, 3 d/week, for 12 consecutive weeks) treatment, and the patients in the control group were given intra-articular injection of sodium hyaluronate (2 mL/time, 1 time/week, for 12 consecutive weeks) combined with isokinetic strength training (2 times/d, 3 d/week, for 12 consecutive weeks). The incidence of adverse reactions during the treatment process and the clinical efficacy at 12 weeks of treatment and 6 months after treatment were recorded, and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scoring system was used to evaluate the knee joint function. When the isokinetic strength training instrument measured an angle of 90°/s, the knee joint flexor and extensor peak torque (PT), total work (TW), and average power (AP) were recorded. Results Forty-nine patients of each group completed the study. The between-group differences in WOMAC pain, stiffness, and joint function scores, and extensor and flexor PT, TW, and AP before treatment were not statistically significant (P>0.05). At 12 weeks of treatment and 6 months after treatment, the WOMAC scores of pain, stiffness, and joint function in the two groups were lower than those before treatment (P<0.05), and the extensor and flexor PT, TW, and AP were higher than those before treatment (P<0.05). Six months after treatment, the WOMAC scores of pain, stiffness, and joint function in the intervention group were lower than those in the control group (P<0.05), and the extensor and flexor PT, TW, and AP in the intervention group were higher than those in the control group (P<0.05). There was no significant difference in the effective rate between the two groups at 12 weeks of treatment (95.9% vs. 89.8%, P>0.05). The effective rate in the intervention group was higher than that in the control group 6 months after treatment (93.9% vs. 79.6%, P<0.05). No serious adverse reaction occurred in the two groups during the treatment. Conclusion Intra-articular injection of PRP can reduce pain, improve muscle strength, and improve joint function in patients with KOA, and the long-term effect is better than that of conventional drugs.
