Comparison of the effects of acupotomy and acupuncture on knee osteoarthritis: A systematic review and meta-analysis

Biomechanically based Fu's subcutaneous needling treatment for senile knee osteoarthritis: protocol for a randomized controlled trial

INTRODUCTION

Fu's subcutaneous needling (FSN) is a new type of acupuncture that uses subcutaneous tissue to oscillate from side to side to improve muscle pathology status and can be effective in treating Knee osteoarthritis. Nonetheless, whether the clinical effect is similar to that of most commonly used drugs is unclear. Thus, this study aims to determine the pain-relieving effect and improvement in the joint function of the FSN therapy by comparing it with that of a positive control drug (celecoxib). Furthermore, this clinical trial also aims to evaluate the effect of FSN on gait and lower limb muscle flexibility, which can further explore the scientific mechanisms of the FSN therapy.

METHODS AND ANALYSIS

This study is a randomized, parallel-controlled, single-center prospective clinical study that includes 60 participants, with an FSN group (n = 30) and a drug group (n = 30). The Fu's subcutaneous needling (FSN) group undergo the FSN therapy 3 times a week for 2 weeks, while the drug group receives 0.2 g/day oral celecoxib for 2 weeks, with a follow-up period of 4 weeks after the completion of treatment. The primary outcome is the difference in the visual analog scale score after 2 weeks of treatment compared with baseline. The Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index, joint active range of motion test, three-dimensional gait analysis, and shear wave elastic imaging technology analysis in lower limb muscles are also performed to demonstrate clinical efficacy.

ETHICS AND DISSEMINATION

The trial is performed following the Declaration of Helsinki. The study protocol and consent form have been approved by the Ethics Committee of Guangdong Provincial Hospital of Chinese Medicine. All patients will give informed consent before participation and the trial is initiated after approval. The results of this trial will be disseminated through publication in peer-reviewed journals.

Effect of Traditional Chinese Non-Pharmacological Therapies on Knee Osteoarthritis: A Narrative Review of Clinical Application and Mechanism

Knee osteoarthritis (KOA) stands as a degenerative ailment with a substantial and escalating prevalence. The practice of traditional Chinese non-pharmacological therapy has become a prevalent complementary and adjunctive approach. A mounting body of evidence suggests its efficacy in addressing KOA. Recent investigations have delved into its underlying mechanism, yielding some headway. Consequently, this comprehensive analysis seeks to encapsulate the clinical application and molecular mechanism of traditional Chinese non-pharmacological therapy in KOA treatment. The review reveals that various therapies, such as acupuncture, electroacupuncture, warm needle acupuncture, tuina, and acupotomy, primarily target localized knee components like cartilage, subchondral bone, and synovium. Moreover, their impact extends to the central nervous system and intestinal flora. More perfect experimental design and more comprehensive research remain a promising avenue in the future.

Acupotomy in Korean Medicine Doctors: A Preliminary Survey on Experiences, Perceptions, and Clinical Usage Status

Acupotomy is a widely used medical intervention in traditional East Asian medicine, and efforts are being made to improve its effectiveness and safety. As a first step toward establishing more standardized procedural guidelines, a survey was conducted to explore the current clinical practice status and perceived adverse events (AEs) by Korean Medicine (KM) practitioners. The survey was developed via expert consensus and included information on clinical usage, perception, and the AEs experienced. The largest acupotomy society in Korea, which consists of 185 KM doctors, participated in an online survey conducted in September 2021. Of the 185 KM doctors, 107 (57.8%) responded. Musculoskeletal and connective tissue diseases accounted for 80.8% of suggested indications by KM doctors. Regarding the detailed procedure, there were considerable discrepancies between KM doctors. The most frequent acupotomy-related AEs observed by KM practitioners were bruises (77.3%), fatigue (57.7%), pain (51.8%), and hematoma (51.8%). Only 1.8% of the respondents answered that they had experienced severe AEs. Survey respondents answered that the use of imaging devices during acupotomy and the development of clinical practice guidelines are the most necessary policy requirements for promoting the use and ensuring the safety of acupotomy. To the best of our knowledge, this study marks the initial exploration into the KM physicians' clinical usage status, AEs experienced, and their requests for standardized guidelines and expanded health insurance coverage concerning acupotomy. Further research should include qualitative studies to assess patient experience and prospective observational studies to examine the effects of operator skills and treatment modalities on AEs and adherence.

Effectiveness and Safety of Acupotomy Treatment on Shoulder Pain: 25 Multicenter Retrospective Study

Objective

Shoulder pain is a common complaint in outpatient clinics and can result in an inability to work or perform household activities, leading to significant socioeconomic burden. Acupotomy, as one kind acupuncture that has flat knife-shaped tip, has been widely used for treating shoulder pain. However, despite the widespread use of acupotomy in primary medical institutions, large sample size clinical trials have not sufficiently been performed. In this respect, this multi-center retrospective study aimed to investigate the effectiveness and safety of acupotomy in reducing shoulder pain and disability using data from multi-center primary care clinics.

Methods

This study was conducted in 25 Korean medicine clinics affiliated with the Korean Medical Society of Acupotomology, Republic of Korea, from August 2021 to December 2021. The medical records of patients who visited the clinics complaining of shoulder pain were gathered, and among them were those of patients who underwent acupotomy treatment and those who received acupuncture combined therapy. The Numeric Rating Scale (NRS), SPADI (Shoulder Pain and Disability Index), Range of Motion (ROM) and adverse event were evaluated at each visit. A linear mixed-effects models and paired t-test were used to identify the effectiveness of the treatment.

Results

Overall analysis showed that the NRS score of patients decreased from 4.95 ± 1.97 before treatment to 3.78 ± 2.03 after treatment (n = 332, difference in NRS score, 1.17; 95% CI: 0.96-1.38, t = 10.89 p < 0.001). SPADI score decreased from 19.05 ± 20.44 at baseline before treatment to 12.12 ± 17.26 after the last visit, which was statistically significant (n = 332, mean difference in SPADI score, 6.93; 95% CI: 4.71-9.15, t = 6.150, p < 0.001). No serious adverse event was reported in both groups.

Conclusion

This study showed the effectiveness of acupotomy therapy for shoulder pain, and as the treatment sessions increased, the effect of pain reduction and shoulder function improvement were also increased.
