Abstract BackgroundIn this study we focused on evaluating the effect of intra-articular platelet-rich plasma (PRP) and hyaluronic acid (HA) on the qualitative and quantitative properties of the articular cartilage in patients with knee osteoarthritis (OA).MethodsWe evaluated 264 patients undergoing treatment of moderate knee OA. Patients aged between 40 and 70 years were included with articular K-L stage ≤ 2. Patients were randomized into three groups and treated with three doses of intra-articular PRP, HA, or placebo injection. Patients were evaluated clinically and by using T2 mapping.ResultsBoth PRP (619.05 ± 243 ms; p = 2.7 × 10− 5) and HA (637.12 ± 273 ms; p = 1.×10− 4) group showed statistically significant lower post-application T2 relaxation times in comparison to the placebo group (859.80 ± 406 ms).Cartilage thickness increased significantly after PRP (2.41±0.87 vs. 2.58±0.97 mm, p=0.033) and HA (2.28±0.81 vs. 2.80±1.00 mm, p=1.8×10) applications. There was a significant decrease in WOMAC pain score by 30% (p=0,001) and the overall WOMAC score by 27 p=1.9×10-4%) in PRP group. The decrease in WOMAC pain score and the overall WOMAC score in the placebo group was similar to the results observed in the PRP group. In the HA group a significant decrease in WOMAC pain score by 14% (p=0,005) was observed only at the first follow-up, whereas no difference was observed at the second follow-up. ConclusionsT2 mapping of cartilage tissue may aid to monitor its properties after the intra-articular therapies in knee OA. However, there is a discrepancy between clinical findings and the results of T2 mapping, suggesting questionable grounds for applying intra-articular therapy.

Background: The aim of this study was to compare the efficacy of ozone injection at Tibio-femoral joint with Supra-patellar recess on knee osteoarthritis (OA). Methods: In this randomized, controlled clinical trial, 99 patients with symptomatic knee OA were randomized into two groups. 47 patients selected to receive 7-8 ml ozone (20 µg/ml) through Tibio-femoral joint injection, and 49 patients received 10 ml ozone (20 µg/ml) through supra-patellar recess injection by using in-plane ultrasound-guided. The primary outcome was the change from baseline in the visual analogue scale (VAS) (0-100 mm) pain score during 3 months after injection. Secondary outcome measures included the Western Ontario and McMaster universities OA Index (WOMAC), Lequesne index, time “Up and Go” (TUG) test, single-limb stance (SLS) tests, patient satisfaction, and adverse effects. All of these measurements were evaluated at the base time, 48 hours, 2 weeks, 1 month, 2 months, and 3 months after injection. Results: Both groups had significantly improvement in the primary and secondary outcome measures. VAS pain score except at the 3–month follow-up (16.8±13.3 versus 18.1±16.6, 95% CI, -7.33 to 4.73, p =0.6), WOMAC pain score, WOMAC stiffness score at all evaluated times, and WOMAC total score at 48 hours after injection (95% CI, -19.4 to -4.9) were significantly better among Tibio-femoral ozone injection compare to Supra-patellar recess injection (95% CI, -20.68 to -6.51, p<0.001)). In both groups satisfaction, TUG and SLS times were improved, but no significant difference was seen between groups (p>0.05). At the 3-month follow-up, WOMAC pain and total scores for only Tibio-femoral joint injection group as well as WOMAC function, TUG and SLS times for both groups were gradually coming back to the baseline. Conclusion: Ozone injection in both groups was associated with pain relief, functional improvement, and quality of life in patient with knee OA. Pain and stiffness of joint were improved better in Supra-patellar recess ozone injection.

Background and Purpose. Knee osteoarthritis (OA) is a major public health problem, and currently, few effective medical treatments exist. Chinese acupotomy therapy has been widely used for the treatment of knee OA in China. We conducted this systematic review and meta-analysis to evaluate the efficacy of Chinese acupotomy in treating knee OA to inform clinical practice. Methods. We performed a comprehensive search on PubMed, the Cochrane Library, EMBASE, and four Chinese databases for articles published prior to June 2020. We included only randomized controlled trials (RCTs) that used acupotomy therapy as the major intervention in adults with knee OA, were published in either Chinese and English, included more than 20 subjects in each group, and included pain and function in the outcome measures. Knee OA was defined by the American College of Rheumatology or Chinese Orthopedic Association criteria in all studies. We extracted the visual analogue scale (VAS) pain score, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score, the total effectiveness rate, the modified Japanese Orthopedic Association (JOA) activities of daily living score, and Lysholm’s score. We calculated the mean difference (MD) or risk ratio (RR) for all relevant outcomes. Meta-analyses were conducted using random-effects models when appropriate. Results. We identified 1317 potentially relevant studies, thirty-two of which met the eligibility criteria and were conducted in China between 2007 and 2020. A total of 3021 knee OA patients (62.96% female, median age: 57 years, and median disease duration: 33 months) were included. The treatment duration ranged from 1 week to 5 weeks (median: 3 weeks). The typical acupotomy treatment involved releasing soft tissue adhesions and was performed once a week for 1–5 weeks until the pain was relieved. The control group treatments included acupuncture (8 studies), electroacupuncture (10 studies), sodium hyaluronate (8 studies), radiofrequency electrotherapy (1 study), and nonsteroidal anti-inflammatory drugs (NSAIDs, 5 studies). The results from the meta-analysis showed that acupotomy led to superior improvements in the VAS pain score (MD = −1.11; 95% confidence interval (CI), −1.51 to −0.71; p  < 0.00001) and WOMAC pain score (MD = −2.32; 95% CI, −2.94 to −1.69; p  < 0.00001), a higher total effectiveness rate (RR = 1.15; 95% CI, 1.09–1.21; p  < 0.00001), and superior improvements in the JOA score (MD = 6.39; 95% CI, 4.11–9.76; p  < 0.00001) and Lysholm’s score (MD = 12.75; 95% CI, 2.61–22.89; p  = 0.01) for overall pain and function. No serious adverse events were reported. Conclusion. Chinese acupotomy therapy may relieve pain and improve function in patients with knee OA. Furthermore, rigorously designed and well-controlled RCTs are warranted.

Abstract Background Osteoarthritis (OA) is a degenerative disease which presents with joint pain and stiffness and reduced mobility. Knee OA is the commonest cause of disability in adults. Dextrose prolotherapy is a new option used to treat mild-to-moderate knee OA. Neural prolotherapy (NPT) is multiple small injections under the skin targeting painful areas with natural substances. The aim of work was to evaluate and compare neural prolotherapy versus intra-articular dextrose prolotherapy effect on relieving pain and improving disability of knee OA. Results VAS and WOMAC scores improved significantly immediately and at 3 and at 6 months, respectively, in group I compared with group II (P < 0.001). The decrease in VAS scores and all the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in group I along the follow-up period in comparison with the baseline scores was statistically significant (P < 0.001). In group II, only WOMAC pain and stiffness scores improved significantly. ROM showed insignificant increase in both groups at 3 and 6 months assessment. On follow-up, range of motion increased in both groups and reached significance in group I (P = .002). Conclusion Dextrose prolotherapy both intra-articular and periarticular (neural) is a very effective and cheap therapy for knee OA with good patient selection. Neural prolotherapy significantly relieves pain and improves function in patients with knee osteoarthritis when compared with intra-articular prolotherapy thus avoiding hazards of intra-articular knee injections.

Abstract Background: Inflammatory mediators in the synovial fluid (SF) play critical roles in the initiation and development of pain in knee osteoarthritis (KOA). However, the expression of inflammatory mediators is controversial and the role of SF inflammatory mediators in neuropathic pain is not clear. Therefore, the aim of this study is to identify the SF inflammatory mediators associated with nociceptive and neuropathic pain in KOA. Methods: The levels of IL-1β, IL-6, TNF-α, macrophage colony-stimulating factor, MMP-3, MMP-13, metalloproteinase with thrombospondin motifs 5, calcitonin gene-related peptide, neuropeptide Y, substance P and bradykinin were measured in 86 patients using enzyme-linked immunosorbent assays. Nociceptive pain was measured using the numeric rating scale (NRS), visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score. Neuropathic pain was measured using the PainDETECT questionnaire. Moreover, knee function was evaluated by the WOMAC score and range of motion (ROM) assessments. Radiological grade was defined using the Kellgren-Lawrence (K-L) grading scale. Results: Pain scores measured using different methods were highly correlated to each other. The worse the pain, the worse the K-L grade and knee function were. The expression of IL-1β and IL-6 was increased in the early stage compared with the late stage. The NRS was positively correlated to age, K-L grade, and the WOMAC score and negatively correlated to ROM and TNF-α expression. The VAS was positively correlated to age, K-L grade, and the WOMAC score but negatively correlated to ROM and the levels of IL-1β, IL-6 and TNF-α. The WOMAC pain score was not correlated to any of the measured inflammatory mediators; it correlated to only ROM. The PainDETECT score correlated to only the WOMAC score. The expression of other inflammatory mediators was not correlated to any of the pain scores. Conclusions: IL-1β, IL-6 and TNF-α play critical roles in pain in the early stage of KOA and correlated to pain. The measured catabolic enzymes and neuropeptides are not correlated to nociceptive and neuropathic pain. New biomarkers related to pain in the late stage need to be further investigated.

Objective. To evaluate the efficacy and safety of Tongning Gel (TNG) compared to placebo-controlled (PC) for knee osteoarthritis (KOA). Methods. A multicentre, randomized, double-blinded, parallel, placebo-controlled, clinical trial was performed in 576 patients (432 patients in the TNG group, 144 patients in the PC group), and 1 in the experimental group withdrew due to nonuse of drug. Patients were randomized to receive TNG or PC applied to knee skin at 3g per time, 2 times per day, which lasted for 3 weeks. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score was used to evaluate the primary efficacy of TNG and WOMAC stiffness and physical function and total scores were used to evaluate the secondary efficacy of TNG. All participants who received at least one dose of study drug were included in the safety analysis. This trial has been registered in Chinese Clinical Trial Registry (no. CTR20131276). Results. Primary efficiency outcome: there were significant differences in the decreased value of WOMAC pain score between two groups (P<0.05), and the decreased value of WOMAC pain score in the TNG group were better than those in the PC group (P<0.05). Secondary efficiency outcome: the WOMAC total score, WOMAC stiffness score, WOMAC physical function score, and the decrease of the above indexes of the two groups of patients after treatment were statistically significant (P<0.05), and the improvement of the above indexes in the TNG group was better than that of the PC group (P<0.05). Safety Evaluation. A total of 42 adverse events were reported by 29 patients: 25 adverse events reported by 16 patients (3.71%) in the experimental group and 17 adverse events were reported by 13 patients (9.03%) in the control group. And 8 adverse reactions were reported by 6 patients including 2 adverse reactions by 2 patients (0.46%) in the experimental group and 6 adverse reactions by 4 patients (2.78%) in the control group. Two cases of significant adverse events occurred in the experimental group. Both groups had one serious adverse event, respectively, which were not relevant to the intervention. Conclusion. These results of the trial demonstrate that TNG is superior to placebo in the treatment of patients with KOA, and TNG can improve other symptoms of KOA, such as stiffness and physical function. TNG is safe for the treatment of knee osteoarthritis as a whole.

Platelet concentration is one of the important factors in OA treatment with platelet-rich plasma (PRP). The purpose of this study was to determine the effect of PRP quality, which was determined by its platelet concentration, on Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in early-stage knee OA patients. This study involved 50 patients diagnosed with early-stage knee OA (stage I to III). Twenty-five patients received PRP with moderate platelet concentration (1× to 4×), another twenty-five patients received PRP with high platelet concentration (>4× to 6×). Patients were evaluated using WOMAC questionnaire before and three months after injection with PRP. Bivariate analysis showed that there was a significant improvement of three WOMAC score subscales (pain, stiffness, and function) in both group (p<0.05) and a significant difference in the differences between WOMAC pain scores between the two groups (p<0.05), meanwhile, significant differences in the differences between WOMAC stiffness and function scores between the two groups weren’t found (p>0.05). The conclusions of this study was, PRP with moderate and high platelet concentration had been shown to improve the three WOMAC score subscales of early-stage knee OA patients, but the effect of PRP’s platelet concentration was only significant in the improvement of WOMAC pain score.

Aims The primary aim of this study was to assess whether patient satisfaction one year after total knee arthroplasty (TKA) changed with longer follow-up. The secondary aims were to identify predictors of satisfaction at one year, persistence of patient dissatisfaction, and late onset dissatisfaction in patients that were originally satisfied at one year. Patients and Methods A retrospective cohort consisting of 1369 patients undergoing a primary TKA for osteoarthritis that had not undergone revision were identified from an established arthroplasty database. Patient demographics, comorbidities, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and Short Form 12 (SF-12) questionnaire scores were collected preoperatively, and one and five years postoperatively. In addition, patient satisfaction was assessed at one and five years postoperatively. Logistic regression analysis was used to identify independent predictors of satisfaction at one and five years. Results The overall rate of satisfaction did not change from one (91.7%, n = 1255) to five (90.1%, n = 1234) years (p = 0.16). Approximately half (n = 53/114) of the patients who were dissatisfied at one year became satisfied with their TKA at five years, whereas 6% (n = 74/1255) of those who were satisfied at one year became dissatisfied at five years. At one year, patients with lung disease (p = 0.04), with depression (p = 0.001), with back pain (p <  0.001), undergoing unilateral TKA (p = 0.001), or with a worse preoperative WOMAC pain score (p = 0.04) were more likely to be dissatisfied. Patients with gastric ulceration (p = 0.04) and a worse WOMAC stiffness score (p = 0.047) were at increased risk of persistent dissatisfaction at five years. In contrast, a worse WOMAC pain score (p = 0.01) at one year was a predictor of dissatisfaction in previously satisfied patients at five years. Conclusion Three groups of dissatisfied patients exist after TKA: ‘early’ dissatisfaction at one year, ‘persistent’ dissatisfaction with longer follow-up, and ‘late’ dissatisfaction developing in previously satisfied patients at one year. All three groups have different independent predictors of satisfaction, and potentially addressing risk factors specific to these groups may improve patient outcome and their satisfaction.

Abstract Objectives To identify literature reporting on thermal mineral water and mud therapy effectiveness on pain, stiffness and knee function in patients with knee osteoarthritis. Design Systematic evidence scan of MEDLINE and PubMed was performed to identify the randomized controlled trial studies published from 2004 to December 2018. Study selection Papers reporting the effect of balneotherapy and mud therapy for treating knee OA, a duration of ≥2 weeks and in which Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were used as an outcome measure. Data extraction Not RCT, Studies not in English. Results A quantitative meta-analysis of ten studies (831 patients) was performed. Five clinical studies (407 patients) measured effectiveness of balneotherapy and there was significant difference between the groups in WOMAC pain score, WOMAC stiffness score and WOMAC function score, with the differences in favour of balneotherapy. Six clinical studies (500 patients) measured effectiveness of mud therapy and there was significant difference between the groups in WOMAC pain score, WOMAC stiffness score and WOMAC function score, with the differences in favour of mud therapy. Conclusion This meta-analysis indicates that balneotherapy and mud therapy were clinically effective in relieving pain, stiffness, and improving function, as assessed by WOMAC score.
