A Randomised Controlled Trial published in 2021 in the journal Advances in Integrative Medicine found that Pomegranate peel extract supplementation can decrease total cholesterol and triglyceride levels while boosting antioxidant status in obese women with knee osteoarthritis. The research was a randomized, double-blind placebo-controlled trial involving 66 obese women aged 38 to 60 years old with knee osteoarthritis. These participants were split into two groups, the intervention group and control group, each containing 33 members. The intervention group received pomegranate peel extract capsules (500 mg) twice daily for 8 weeks including standard drug therapy while the control group was given a placebo during the same period. All participants' fasting blood samples, anthropometric measurements, dietary intake data, and physical activity levels were collected both before the start and at the end of the trial. Results analysis showed that pomegranate peel extract supplementation brought down levels of serum total cholesterol, triglyceride and an oxidative stress marker while enhancing levels of some antioxidant enzymes and the overall antioxidant capacity when compared to the control group. However, there were no noticeable alterations between the two groups in terms of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and body mass index by the end of the experiment.
A Systematic Review published in 2020 in the journal Current Rheumatology Reports found that The majority of studies concluded the superiority of short-term analgesic effects over various controls and suggested that acupuncture may be efficacious for chronic musculoskeletal pain. We examined 16 review articles and 11 randomized controlled trials published in the last 5 years on the clinical efficacy of acupuncture in adults with CMP conditions. The available evidence suggests that acupuncture does have short-term pain relief benefits for patients with symptomatic knee osteoarthritis and chronic low back pain and is a safe and reasonable referral option. Acupuncture may also have a beneficial role for fibromyalgia. However, the available evidence does not support the use of acupuncture for treating hip osteoarthritis and rheumatoid arthritis.
A Systematic Review published in 2020 in the journal Clinical Rehabilitation found that Tai Chi exercise was beneficial for ameliorating physical and mental health of patients with knee osteoarthritis and should be available as an alternative non-pharmacological therapy in rehabilitation programmes. A total of 16 RCTs involving 986 patients with knee osteoarthritis met the established inclusion criteria. The strength of evidence for the main outcomes was low or moderate. The systematic review illustrated the efficacy of Tai Chi exercise in treating and managing knee osteoarthritis. Patients’ outcomes practising Tai Chi exercise were improved significantly, including pain, stiffness, physical function, dynamic balance, physiological and psychological health. No adverse events associated with Tai Chi exercise were reported.
A Systematic Review published in 2020 in the journal Journal of Acupuncture and Tuina Science found that In the treatment of knee osteoarthritis, the acupuncture group had significant advantages over sham acupuncture or no-acupuncture groups in relieving pain and improving physical function. Eight databases were extensively searched up to March 2018. Randomized controlled trials (RCTs) comparing the efficacy of acupuncture with sham acupuncture or no acupuncture for knee osteoarthritis were included. The Cochrane Collaboration’s tool was used for assessing the risk of bias. A total of 18 RCTs were included, involving a total of 3 522 participants. The results showed that acupuncture was superior to sham acupuncture in relieving pain and improving physical function. In comparison to the no-acupuncture group, the acupuncture group also showed significant advantages in relieving pain and improving physical function. Sensitivity analyses suggested that the results were robust, and Egger’s test found no potential publication bias.
A Randomised Controlled Trial published in 2020 in the journal Acupuncture in Medicine found that Electroacupuncture might provide stronger impact on knee osteoarthritis than manual acupuncture, though both methods are safe and feasible treatments. The study consisted of a multicenter randomized controlled clinical trial conducted in Beijing, during which 60 participants suffering from knee osteoarthritis were split into two groups: Electroacupuncture and Manual Acupuncture. Participants in both groups were treated at the same local traditional acupuncture points, with the Electroacupuncture group using an electrical apparatus. The Manual Acupuncture group experienced a sham procedure, utilizing a working power indicator but no actual current, to keep the participants blind to the experimental conditions. Over 8 weeks, both groups received 24 treatment sessions. The successfulness of the treatments was determined by response rates, pain, stiffness, functionality, and quality of life. In the results, 53 out of 60 participants completed the study. Within these participants, the response rates were 43% for the Electroacupuncture group and 30% for the Manual Acupuncture group. Differences between group outcomes were noted but not deemed statistically significant. There were low rates of adverse effects in correspondence with the two methods, which were also evenly distributed across the two groups.
A Systematic Review published in 2019 in the journal International Journal of Rheumatic Diseases found that Avocado-soybean unsaponifiables treatment is effective in reducing knee osteoarthritis symptoms without increasing adverse events, contrary to those with hip osteoarthritis. To assess avocado-soybean unsaponifiables (ASU) effectiveness and safety, a systematic review and meta-analysis of randomized controlled trials involving patients with hip or knee osteoarthritis was conducted. Various scientific databases, including Medline, SCOPUS, Web of Science, and Google Scholar, were thoroughly searched for suitable trials. Selection criteria consisted of randomized placebo-controlled trials wherein the effect of orally administered ASU on knee or hip osteoarthritis symptoms were evaluated, primarily using the Lequesne index, visual analog scale, and joint space width. The meta-analysis revealed a significant reduction in pain as assessed by the visual analog scale for those under Avocado-soybean unsaponifiables therapy, particularly for patients with knee osteoarthritis, indicated by a decrease in both the visual analogue scale and Lequesne index. However, no such significant effect was found for patients with hip osteoarthritis. In terms of safety, there were no significant differences in adverse events between patients receiving ASU and those given a placebo, confirming ASU's relative safety as a treatment option.
A Systematic Review published in 2019 in the journal Medicine found that According to high-quality outcomes, acupuncture had more total effective rate, short-term effective rate, and less adverse reactions than western medicine in treating knee osteoarthritis. Firstly, this overview provides the latest evidence on acupuncture for knee osteoarthritis based on the findings of systematic reviews, which indicated that acupuncture may have more total effective rate, short-term effective rate, and less adverse reactions in treating knee osteoarthritis than western medicine. Secondly, this overview is predesigned, which helps restrict the likelihood of biased decisions in reviewing. Thirdly, comprehensive search strategies were conducted for a wide range of data. Fourthly, independent reviewers were engaged in searching, screening, and assessing the potential studies and there was a high consistency among the reviewers.
A Randomised Controlled Trial published in 2018 in the journal Clinical Interventions in Aging found that The extract from cucumber, Q-Actin, is effective in reducing moderate knee osteoarthritis related pain and potentially in managing knee pain, stiffness, and physical functions. In this double-blind, parallel-group clinical trial conducted in three different centres, 122 patients aged between 40 and 75 years with diagnosed moderate knee Osteoarthritis were randomly divided into two groups. Over a 180-day period, one group received the cosmetically prescribed dose of 1,350 mg of glucosamine-chondroitin orally twice daily, and the other group took an orally administered 10 mg of Q-Actin (aqueous extract of cucumber) twice per day. The results showed a significant decrease in Osteoarthritis Index scores in the group that received the cucumber extract, indicating reduced pain and improved physical function. This trend was observed throughout the trial, and by the 180th day, the extract's effectiveness was substantially higher than that of the traditionally prescribed glucosamine-chondroitin. Notably, no adverse effects from the cucumber extract were reported during the trial period.
A Review Article published in 2017 in the journal PLOS One found that Traditional Chinese Medicine offers potential benefits like pain relief and functional improvement for knee osteoarthritis with few adverse events. Five electronic databases were searched up until April 2016 to study the efficacy and safety of Traditional Chinese Medicine (TCM) for treating knee osteoarthritis. The methodological quality of the included studies was evaluated using the Assessment of Multiple Systematic Reviews (AMSTAR) and the Risk of Bias in Systematic reviews (ROBIS) tools. The quality of evidence was determined using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The findings indicate that TCM potentially benefits patients with knee osteoarthritis through pain relief, functional improvement, and few adverse effects. However, deficiencies were found in the methodological quality of the reviews, such as the absence of an a-priori protocol or protocol registration, and an incomplete literature search. Furthermore, none of the studies offered a list of excluded studies. Overall, the quality of evidence in the systematic reviews was deemed poor, ranging from 'very low' to 'low'. This shortcoming was primarily due to a substantial risk of bias in the original trials, inconsistencies, and imprecision in the outcomes. Though TCM generally appears to be effective for knee osteoarthritis treatment, the evidence is not strong enough due to methodological flaws. Therefore, these findings should be approached cautiously in a clinical setting.
A Systematic Review published in 2017 in the journal Acupuncture in Medicine found that Acupuncture may be effective at relieving chronic knee pain 12 weeks after acupuncture administration. Nineteen trials were included in this systematic review. Of these, data from 17 studies were available for analysis. Regarding the effectiveness of acupuncture alone or combined with other treatment, the results of the meta-analysis showed that acupuncture was associated with significantly reduced CKP at 12 weeks on WOMAC pain subscale and VAS. As for safety, no difference was found between the acupuncture and control groups.
A Systematic Review published in 2016 in the journal Complementary Medicine Research found that Acupuncture therapy is more effective than NSAID in improving clinical efficacy rates and pain scores for treatment of chrondomalacia patellae. To our knowledge, this is the first meta-analysis of acupuncture therapy in the treatment of CMP. Seven RCT involving 707 patients with CMP were selected for this meta-analysis. Based on the findings of the present systematic review, acupuncture therapy can further improve the clinical effect and pain scores when compared with NSAID controls. However, the potential beneficial effect of acupuncture is possibly overstated owing to the low general methodological quality of the included RCT. Conclusions regarding the safety of acupuncture therapy cannot be drawn since the eligible trials provide no evidence on this aspect.
