OBJECTIVE: As management for osteoarthritis, clinical practice guidelines (CPGs) have been published worldwide with the aim of attaining optimal treatment and rehabilitation. However, we suspect a lack of knowledge of and/or adherence to osteoarthritis CPGs in physiotherapists\' clinical practice. There may be an evidence-to-practice gap in knee osteoarthritis rehabilitation among Japanese physiotherapists. Therefore, we aimed to measure the level of knowledge and adherence to osteoarthritis CPGs within a cohort of Japanese physiotherapists.
METHODS: An online survey was created based on three appropriate and high-quality CPGs. The first two sections comprised 23 statements, and participants responded via a five-point Likert scale (\"completely disagree\" to \"completely agree\"). Consensus was defined as ≥70% agreement with a statement. In the second section, participants read clinical scenarios and selected what they considered to be the most appropriate management and interventions.
RESULTS: The survey was completed by 558 Japanese physiotherapists. The mean age of the participants included in the analysis was 34.8 years, 61 participants were female (13.7%). Consensus was attained in just 12 out of 23 items (52%). In the second section, none of the physiotherapists were considered to have good knowledge of CPGs, 85.2% were considered to have only partial knowledge, and 14.8% had no knowledge. Familiarity with the CPGs was therefore poor and there was clearly poor adherence to the recommended rehabilitation guidelines.
CONCLUSIONS: The level of knowledge and adherence to osteoarthritis CPGs within our cohort was poor, suggesting an evidence-to-practice gap in rehabilitation for knee osteoarthritis among Japanese physiotherapists.

Knee osteoarthritis (KOA) is a common geriatric disease in middle-aged and elderly people. Its main pathological characteristics are articular cartilage degeneration, changes in subchondral bone reactivity, osteophyte formation at joint edges, synovial disease, ligament relaxation or contracture, and joint capsular contracture. The prevalence rate of symptomatic KOA in middle-aged and elderly people in China is 8.1%, and this is increasing. The main clinical manifestations of this disease are pain and limited activity of the knee joint, which seriously affect the quality of life of patients and may cause disability, posing a huge burden on society and the economy. Although the pathogenesis of KOA is not clear, the treatment of KOA is diverse, and Chinese medicine, which mainly relies on plant-based natural products, has a relatively stable and reliable curative effect. This guideline aims to emphasize the evidence-based staging and stepped treatment of KOA and the therapeutic effect of integrative medicine based on traditional Chinese medicine on KOA. We make recommendations that include the adoption of manual therapy, acupuncture, external application of herbs, herbal plasters, exercise therapy, and other integrative medicine based on traditional Chinese medicine. Users of the above guidelines are most likely to include clinicians and health managers in healthcare settings.

UNASSIGNED: To describe 1) the proportion of patients with knee osteoarthritis (OA) undergoing guideline-adherent core treatments until six months after primary referral to an orthopaedic surgeon, 2) which specific treatment pathways these patients undertake and 3) the characteristics of patients choosing different treatment pathways.
UNASSIGNED: This prospective cohort study consecutively invited patients referred to an orthopaedic surgeon due to knee OA at two Danish hospitals from October 2018 to December 2020. Before and six months after consulting the surgeon, patients answered a questionnaire reporting which treatments they had received for knee OA. The proportion receiving the combination of guideline-adherent treatments (i.e., exercise, education, and dietary weight management if needed) was determined. We evaluated the specific treatment usage before and until six months after the consultation and investigated characteristics of patients undertaking different pathways.
UNASSIGNED: Out of 5251 eligible patients, 2574 (49%) had complete data and were included in analyses. 23% received guideline-adherent treatments, 10% had no treatment. Patients underwent 1143 unique treatment pathways, 62% including treatments not recommended/recommended against. Those who underwent guideline-adherent pathways had similar characteristics to those who did not but tended to be females, retired, had longer-lasting knee problems, have comorbidities, and higher education levels.
UNASSIGNED: Only one in four patients with knee OA received treatment adhering to clinical guidelines before and six months after consulting the surgeon. Patients used many different treatment pathways. There is a need for a structured effort to increase the use of guideline-adherent core treatments.
UNASSIGNED: Registration: NCT03746184, Protocol: PMID: 34233992.

BACKGROUND: Knee osteoarthritis (KOA) is the most common degenerative joint disease in China, causing a huge economic burden on patients, families, and society. Standardized KOA rehabilitation treatment is an important means to prevent and treat the disease and promote the development of high-quality medical services. This guideline is updated on the basis of the 2016 and 2019 editions.
METHODS: Clinical questions regarding rehabilitation assessment and treatment were selected through clinical questions screening and deconstruction, and multiple rounds of Delphi questionnaire consultation. The International Classification of Functioning, Disability and Health (ICF) was used as the theoretical framework, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method was used to grade the quality of evidence and recommendations.
RESULTS: The reporting of this guideline followed the standard of Reporting Items for Practice Guidelines in Healthcare (RIGHT). Taking into account patients\' preferences and values and the needs of Chinese clinical practice, a total of 11 clinical questions and 28 recommendations were established. The clinical questions were grouped into two categories: KOA assessment (body function, body structure, activity and participation, quality of life, and environmental factors and clinical outcomes assessment, resulting in 9 recommendations) and KOA treatment (health education, therapeutic exercise, therapeutic modalities, occupational therapy, assistive devices, and regenerative rehabilitation approaches, resulting in 19 recommendations).
CONCLUSIONS: This is the first evidence-based guideline for KOA rehabilitation in China utilizing the ICF framework. This guideline provides key guidance for developing systematic, standardized, and precise rehabilitation protocols for KOA across various healthcare settings.

BACKGROUND: The aim of this study was to examine the racial and ethnic representation in studies included in the 2015 American Academy of Orthopaedic Surgeons Surgical Management of the Knee Evidence-Based Clinical Practice Guideline relative to their representation of the United States (US).
METHODS: The demographic characteristics reported in articles included in the 2015 American Academy of Orthopaedic Surgeons Surgical Management of the Knee Evidence-Based Clinical Practice Guideline were analyzed. The primary outcome of interest was the representation quotient, which is the ratio of the proportion of a racial/ethnic group in the guideline studies relative to their proportion in the US. There were 211 studies included, of which 15 (7%) reported race. There were 35 studies based in the US and 7 of the US-based studies reported race.
RESULTS: No US-based studies reported race and ethnicity separately, no studies reported American Indian/Alaska Native participants and no US-based studies reported Asian participants. The representation quotient of US-based studies was 0.66 for Black participants, 0.33 for Hispanic participants, and 1.30 for White participants, which indicates a relative over-representation of White participants compared to national proportions.
CONCLUSIONS: This study illustrated that the evidence base for the surgical management of knee osteoarthritis has been constructed from studies which fail to consider race and ethnicity. Of those US-based studies which do report race or ethnicity, study cohorts do not reflect the US population. These results illustrate a disparity in clinical orthopedic surgical evidence and highlight the need for improved research recruitment strategies.

Guideline adherence for hip and knee osteoarthritis management is often poor, possibly related to the quality and/or inconsistent recommendations. This systematic review of hip and knee osteoarthritis guidelines aimed to appraise the quality and consistency in recommendations across higher-quality guidelines.
Eight databases, guideline repositories, and professional associations websites were searched on 27/10/2022. Guideline quality was appraised using the Appraisal of Guidelines for Research and Evaluation II (AGREE II tool) (six domains). Higher quality was defined as scoring ≥60% for domains 3 (rigour of development), 6 (editorial independence), plus one other. Consistency in recommendations across higher-quality guidelines was reported descriptively. This review was registered prospectively (CRD42021216154).
Seven higher-quality and 18 lesser-quality guidelines were included. AGREE II domain scores for higher-quality guidelines were > 60% except for applicability (average 46%). Higher-quality guidelines consistently recommended in favour of education, exercise, and weight management and non-steroidal anti-inflammatory drugs (hip and knee), and intra-articular corticosteroid injections (knee). Higher quality guidelines consistently recommended against hyaluronic acid (hip) and stem cell (hip and knee) injections. Other pharmacological recommendations in higher-quality guidelines (e.g., paracetamol, intra-articular corticosteroid (hip), hyaluronic acid (knee)) and adjunctive treatments (e.g., acupuncture) were less consistent. Arthroscopy was consistently recommended against in higher-quality guidelines. No higher-quality guidelines considered arthroplasty.
Higher-quality guidelines for hip and knee osteoarthritis consistently recommend clinicians implement exercise, education, and weight management, alongside consideration of Non-Steroidal Anti-Inflammatory Drugs and intra-articular corticosteroid injections (knee). Lack of consensus on some pharmacological options and adjunctive treatments creates challenges for guideline adherence. Future guidelines must prioritise providing implementation guidance, considering consistently low applicability scores.

OBJECTIVE: Is acupuncture effective in treating knee osteoarthritis (KOA)?
BACKGROUND: Although increasingly used in the clinical setting, acupuncture is not mentioned or weakly recommended in guidelines for the treatment of KOA.
CONCLUSIONS: We suggest acupuncture rather than no treatment in adult KOA (weak recommendation, moderate certainty evidence), and acupuncture combined with nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acupuncture alone when KOA symptoms are severe (weak recommendation, moderate certainty evidence), with duration of acupuncture for 4-8 weeks depending on KOA severity and treatment response (weak recommendation, moderate certainty evidence), and discussing with patients in shared decision-making.
UNASSIGNED: This rapid recommendation was developed following the Making GRADE the Irresistible Choice (MAGIC) methodological framework. First, the clinical specialist identified the topic of recommendation and demand for evidence. Then the independent evidence synthesis group performed a systematic review to summarize available evidence and evaluate the evidence using the GRADE approach. Finally, the clinical specialist group produced recommendations for practice through a consensus procedure.
UNASSIGNED: The linked systematic review and meta-analysis included 9422 KOA patients, 61.1% of whom were women. The median mean age was 61.8 years. Compared with no treatment, acupuncture had beneficial effect on KOA in improving the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score (moderate certainty evidence), and WOMAC pain (very low certainty evidence), WOMAC stiffness (low certainty evidence), and WOMAC function (low certainty evidence) subscale scores. Compared with usual care, acupuncture improved WOMAC stiffness subscale score (moderate certainty evidence). Subgroup analyses showed different effects in the improvement of WOMAC total scores by different durations of acupuncture and whether acupuncture combined with NSAIDs, but no difference between manual acupuncture and electroacupuncture was found.
UNASSIGNED: Compared with no treatment, acupuncture is suggested to reduce pain, stiffness, and disfunction in KOA patients, ultimately improving the patient\'s health status. Acupuncture can be used as an alternative therapy when usual care is ineffective or there are adverse reactions so that patients can no longer continue the treatment. Manual acupuncture or electroacupuncture is suggested for 4-8 weeks to improve the health status of KOA. The patient\'s values and preferences should be considered when selecting acupuncture for KOA treatment.

OBJECTIVE: This systematic review summarized the rehabilitation recommendations for treating and managing knee osteoarthritis (OA) in practice guidelines and evaluated their applicability and quality using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.
METHODS: PubMed, the Cochrane Library, EMBASE, CINAHL, PEDro, Guideline central, Guideline International Network and Agency for Healthcare Research and Quality (AHRQ) were used to search for relevant studies published between 1 January 2008 and 31 May 2022.
METHODS: AGREE II was used to evaluate the included guidelines quality, SPSS 25.0 statistical software was used for data analysis, and the intra-group correlation coefficient value was calculated to verify the consistency between the raters. The two-way random effects model was used to calculate concordance scores, and each domain\'s total scores were calculated. Additionally, the median and interquartile range for domain and total scores were calculated.
RESULTS: Twenty-four guidelines recommending knee OA rehabilitation were included. Inter-rater consistency evaluation ranged from 0.62 to 0.90. The domains where the guideline\'s overall and rehabilitation parts scored highest and lowest were scope and purpose (domain 1) and applicability (domain 5), respectively. The highly recommended rehabilitation opinions included aerobic exercise programs (21/24), weight control (16/24), self-education and management (16/24), gait/walking aids (7/24), and tai chi (6/24). However, the orthopedic insole and hot/cold therapy roles remain controversial.
CONCLUSIONS: The clinical practice guidelines\' overall quality for knee OA rehabilitation is good; however, the applicability is slightly poor. Therefore, we should improve the promoting factors and hindering factors, guideline application recommendations, tools, and resources when developing relevant guidelines.

UNASSIGNED: Clinical practice guidelines (CPGs) are vital to establishing a standardized and evidence-based approach in medicine. These guidelines rely on the use of methodologically sound clinical trials, and the subsequent reporting of their methodology.
UNASSIGNED: To evaluate the completeness of randomized controlled trials (RCTs) underpinning CPGs published by the American Academy of Orthopedic Surgeons (AAOS) for management of osteoarthritis of the knee.
UNASSIGNED: We searched the most recent AAOS CPGs for surgical and nonsurgical management of osteoarthritis of the knee for RCTs. To estimate the necessary sample size, we performed a power analysis using OpenEpi 3.0 (openepi.com).
UNASSIGNED: Two authors independently screened the reference sections of the included CPGs. Included studies met the definition of an RCT, were retrievable in the English language, and were cited in at least one of the included CPGs.
UNASSIGNED: Meta-Analysis.
UNASSIGNED: Level 1a.
UNASSIGNED: We performed double-blind screening and extraction of RCTs included in the AAOS CPGs. We evaluated each RCT for adherence to the Consolidated Standards of Reporting Trials (CONSORT) 2010 checklist. A multiple regression analysis was conducted to assess CONSORT adherence against characteristics of included studies (ie, type of intervention, funding source, etc).
UNASSIGNED: Our study included 179 RCTs. The overall adherence was 68.5% with significant differences between those published before and since the development of the 2010 CONSORT guidelines (P = 0.02). We found that RCTs receiving funding from industry/private sources as well as studies that included a conflict of interest statement showed more completeness than RCTs that reported receiving no funding (P < 0.01).
UNASSIGNED: We found suboptimal CONSORT adherence for RCTs cited in AAOS CGPs for management of osteoarthritis of the knee. Therefore, the CPGs are likely supported by outdated evidence and lack of high-quality reporting. It is important that evidence used to guide clinical decision making be of the highest quality in order to optimize patient outcomes. In order for clinicians to confer the greatest benefits to their patients, CPGs should provide the totality of evidence and emphasize emerging high-quality RCTs to ensure up-to-date, evidence-based clinical decision-making.

OBJECTIVE: Most published clinical practice guidelines (CPGs) endorsed therapeutic exercises, education, and body weight management as the gold standard for managing knee osteoarthritis (OA). However, it is difficult to ascertain whether the physiotherapy practice pattern in Ghana uniformly conforms to the generally accepted standard. Our aim was to describe the patterns of physiotherapists\' practice with respect to Knee OA in a low-resource setting.
METHODS: A web-based nationwide cross-sectional survey was performed among registered members of the Ghana Physiotherapy Association. Consented participants were sampled into the study through a purposive sampling method. A self-designed and validated questionnaire was administered to obtain the participants\' awareness of CPGs, while the selection of modalities by the physiotherapists was based on a clinical vignette. Exploratory analysis of data was performed for the association of the age, sex, education, and the number of patients managed per week with the awareness of CPGs, using the Chi-square test at a significance level of p < 0.05.
RESULTS: Of the total 165 participants, only 148 responded and were included for data analysis. Sixty-one (41.2%) of the 148 respondents were aware of specific CPGs for knee OA management, even though 98 (66.2%) utilized OA-specific outcome measures for management evaluation. Majority of the participants (90.5%) commonly selected therapeutic exercises, and 83.8% utilized education for weight management. Transcutaneous electrical nerve stimulation and ice therapy were selected by 68.2% and 66.2% of the respondents, respectively. The number of patients managed per week was not significantly associated (p > 0.05) with the awareness of CPGs.
CONCLUSIONS: Our findings show high utilization of therapeutic exercises and patients\' education in the management of knee OA despite the low awareness of OA-specific CPGs.
UNASSIGNED: The inclusion of passive modalities coupled with the physiotherapists\' low awareness underpins the need for continuing education on condition-specific CPGs.
