OBJECTIVE: To conduct a network meta-analysis comparing all treatments for osteoarthritis (OA) pain in the Cochrane Library. DESIGN: The Cochrane Library and Epistemonikos were searched for randomized controlled trials (RCTs) about treatments for hip and knee OA. We constructed 17 broad categories, comprising drug treatments, exercise, surgery, herbs, orthotics, passive treatments, regenerative medicine, diet/weight loss, combined treatments, and controls. In addition to a full network analysis, we compared the direct/indirect effects, and studies with shorter-/longer follow-up. CINeMA software was used for assessing confidence in network meta-analysis estimates. RESULTS: We included 35 systematic reviews including 445 RCTs. There were 153 treatments for OA. In total, 491 comparisons were related to knee OA, less on hip OA, and only nine on hand OA. Six treatment categories showed clinically significant effects favoring treatment over control on pain. "Diet/weight loss" and "Surgery" had effect sizes close to zero. The network as a whole was not coherent. Of 136 treatment comparisons, none were rated as high confidence, six as moderate, 13 as low, and 117 as very low. CONCLUSIONS: Direct comparison of different available treatment options for OA is desirable, however not currently feasible in practice, due to heterogeneous study populations and lack of clear descriptions of control interventions. We found that many treatments were effective, but since the network as a whole was not coherent and lacked high confidence in the treatment comparisons, we could not produce a ranking of effects.

BACKGROUND & AIMS: Musculoskeletal pain, the most common cause of disability globally, is most frequently managed in primary care. People with musculoskeletal pain in different body regions share similar characteristics, prognosis, and may respond to similar treatments. This overview aims to summarise current best evidence on currently available treatment options for the five most common musculoskeletal pain presentations (back, neck, shoulder, knee and multi-site pain) in primary care. METHODS: A systematic search was conducted. Initial searches identified clinical guidelines, clinical pathways and systematic reviews. Additional searches found recently published trials and those addressing gaps in the evidence base. Data on study populations, interventions, and outcomes of intervention on pain and function were extracted. Quality of systematic reviews was assessed using AMSTAR, and strength of evidence rated using a modified GRADE approach. RESULTS: Moderate to strong evidence suggests that exercise therapy and psychosocial interventions are effective for relieving pain and improving function for musculoskeletal pain. NSAIDs and opioids reduce pain in the short-term, but the effect size is modest and the potential for adverse effects need careful consideration. Corticosteroid injections were found to be beneficial for short-term pain relief among patients with knee and shoulder pain. However, current evidence remains equivocal on optimal dose, intensity and frequency, or mode of application for most treatment options. CONCLUSION: This review presents a comprehensive summary and critical assessment of current evidence for the treatment of pain presentations in primary care. The evidence synthesis of interventions for common musculoskeletal pain presentations shows moderate-strong evidence for exercise therapy and psychosocial interventions, with short-term benefits only from pharmacological treatments. Future research into optimal dose and application of the most promising treatments is needed.

Knee osteoarthritis is a chronic disabling condition that is both progressive and irreversible. Intraarticular steroids are commonly used to reduce osteoarthritis symptoms and to minimize the need for surgery. Nevertheless, debate still exists regarding the efficacy and safety of steroids. To address this point, we searched Epistemonikos database which is maintained by screening 30 separate databases and identified 12 systematic reviews including 41 studies addressing steroids use in knee osteoarthritis. Of these, 40 were randomized trials. The evidence from these studies was combined using meta-analysis, and a summary of findings table was constructed following the GRADE approach. We concluded intraarticular steroid use slightly decreases short-term pain, makes little or no difference in the mid-term, and may have no effects in the long-term.

BACKGROUND: Degenerative osteoarthritis of the knee (OA) affects 35% of persons older than 65 years. If pain persists after non-invasive treatment, some intra-articular drugs can be tried before surgical treatment. QUESTIONS/PURPOSES: The purpose of this article is to review the literature after 2006 with the aim of answering two questions: (1) Are intra-articular injections of corticosteroids (CS), hyaluronic acid (HA) and platelet-rich plasma (PRP) effective in painful knee OA? and (2) Which of these drugs is more effective? METHODS: The search engines were MedLine and the Cochrane Library. The keywords used were: knee, osteoarthritis, and intra-articular injections. Eight hundred and forty-four articles were found but only 142 had been published after 2006. Of those, only 14 were selected and reviewed because they were strictly focused on the topic and the questions of this article. RESULTS: The clinical efficacy of intra-articular injections of HA and CS in patients with knee OA has been demonstrated. Pain reduction after three to five weekly injections of HA lasts between 5 to13 weeks (sometimes up to 1 year). Pain reduction is less durable after CS injections (2 to 3 weeks). Recent reports indicate that PRP could have a better performance than HA in younger patients. CONCLUSIONS: Three to five weekly intra-articular injections of HA are recommendable in patients with knee OA before surgical treatment. CS injections have a very short effect. The efficacy and duration of PRP injections require further studies.

INTRODUCTION: Osteoarthritis of the knee affects about 10% of adults aged over 60 years, with risk increased in those with obesity, and joint damage or abnormalities. Progression of disease on x rays is commonplace, but x ray changes don't correlate well with clinical symptoms. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of non-surgical treatments for osteoarthritis of the knee? What are the effects of surgical treatments for osteoarthritis of the knee? We searched: Medline, Embase, The Cochrane Library and other important databases up to October 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 74 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, capsaicin, chondroitin, education to aid self-management, exercise and physiotherapy, glucosamine, insoles, intra-articular corticosteroids, intra-articular hyaluronan, joint bracing, knee replacement, non-steroidal anti-inflammatory drugs (including topical non-steroidal anti-inflammatory drugs), opioid analgesics, osteotomy, simple analgesics, and taping.
