Osteoarthritis is the most prevalent chronic articular disease, in which pain is one of the main symptoms and a major determinant of functional loss. Several therapeutic options have been proposed, including glucosamine, but its actual usefulness has not yet been established. To answer this question, we searched in Epistemonikos database, which is maintained by screening multiple databases. We identified 11 systematic reviews including 35 randomized trials answering the question of interest. We extracted data, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded it is not clear whether glucosamine decreases pain or improves functionality in osteoarthritis because the certainty of the evidence is very low.

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.

Post-operative pain affects millions of patients worldwide and the post-operative period has high rates of morbidity and mortality. Some of this morbidity may be related to analgesics. The aim of this review was to provide an update of current knowledge of adverse events (AE) associated with the most common perioperative non-opioid analgesics: paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids (GCCs), gabapentinoids and their combinations. The review is based on data from systematic reviews with meta-analyses of analgesic efficacy and/or adverse effects of perioperative non-opioid analgesics, and randomised trials and cohort/retrospective studies. Generally, data on AE are sparse and related to the immediate post-operative period. For paracetamol, the incidence of AEs appears trivial. Data are inconclusive regarding an association of NSAIDs with mortality, cardiovascular events, surgical bleeding and renal impairment. Anastomotic leakage may be associated with NSAID usage. No firm evidence exists for an association of NSAIDs with impaired bone healing. Single-dose GCCs were not significantly related to increased infection rates or delayed wound healing. Gabapentinoid treatment was associated with increased sedation, dizziness and visual disturbances, but the clinical relevance needs clarification. Importantly, data on AEs of combinations of the above analgesics are sparse and inconclusive. Despite the potential adverse events associated with the most commonly applied non-opioid analgesics, including their combinations, reporting of such events is sparse and confined to the immediate perioperative period. Knowledge of benefit and harm related to multimodal pain treatment is deficient and needs clarification in large trials with prolonged observation.

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.

OBJECTIVES: To update a previous report on the comparative benefits and harms of oral non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, over-the-counter supplements (chondroitin and glucosamine), and topical agents (NSAIDs and rubefacients, including capsaicin) for osteoarthritis. DATA SOURCES: Ovid MEDLINE (1996–January 2011), the Cochrane Database (through fourth quarter 2010), and reference lists. REVIEW METHODS: We included randomized trials, cohort studies, case-control studies, and systematic reviews that met predefined inclusion criteria. For each study, investigators abstracted details about the study population, study design, data analysis, followup, and results, and they assessed quality using predefined criteria. We assessed the overall strength of each body of evidence using predefined criteria, which included the type and number of studies; risk of bias; consistency; and precision of estimates. Meta-analyses were not performed, though pooled estimates from previously published studies were reported. RESULTS: A total of 273 studies were included. Overall, we found no clear differences in efficacy for pain relief associated with different NSAIDs. Celecoxib was associated with a lower risk of ulcer complications (RR 0.23, 95% CI 0.07 to 0.76) compared to nonselective NSAIDs. Coprescribing of proton pump inhibitors, misoprostol, and H2-antagonists reduce the risk of endoscopically detected gastroduodenal ulcers compared to placebo in persons prescribed NSAIDs. Celecoxib and most nonselective, nonaspirin NSAIDs appeared to be associated with an increased risk of serious cardiovascular (CV) harms. There was no clear association between longer duration of NSAID use or higher doses and increased risk of serious CV harms. There were no clear differences between glucosamine or chondroitin and oral NSAIDs for pain or function, though evidence from a systematic review of higher-quality trials suggests that glucosamine had some very small benefits over placebo for pain. Head-to-head trials showed no difference between topical and oral NSAIDs for efficacy in patients with localized osteoarthritis, lower risk of gastrointestinal (GI) adverse events, and higher risk of dermatological adverse events, but serious GI and CV harms were not evaluated. No head-to-head trials compared topical salicylates or capsaicin to oral NSAIDs. CONCLUSIONS: Each of the analgesics evaluated in this report was associated with a unique set of risks and benefits. Choosing the optimal analgesic for an individual with osteoarthritis requires careful consideration and thorough discussion of the relevant tradeoffs.

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.

OBJECTIVES: Systematic review of outcomes of three treatments for osteoarthritis (OA) of the knee: intra-articular viscosupplementation; oral glucosamine, chondroitin or the combination; and arthroscopic lavage or debridement. DATA SOURCES: We abstracted data from: 42 randomized, controlled trials (RCTs) of viscosupplementation, all but one synthesized among six meta-analyses; 21 RCTs of glucosamine/chondroitin, 16 synthesized among 6 meta-analyses; and 23 articles on arthroscopy. The search included foreign-language studies and relevant conference proceedings. REVIEW METHODS: The review methods were defined prospectively in a written protocol. We sought systematic reviews, meta-analyses, and RCTs published in full or in abstract. Where randomized trials were few, we sought other study designs. We independently assessed the quality of all primary studies. RESULTS: Viscosupplementation trials generally report positive effects on pain and function scores compared to placebo, but the evidence on clinical benefit is uncertain, due to variable trial quality, potential publication bias, and unclear clinical significance of the changes reported. The Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), a large (n=1,583), high-quality, National Institutes of Health-funded, multicenter RCT showed no significant difference compared to placebo. Glucosamine sulfate has been reported to be more effective than glucosamine hydrochloride, which was used in GAIT, but the evidence is not sufficient to draw conclusions. Clinical studies of glucosamine effect on glucose metabolism are short term, or if longer (e.g., 3 years), excluded patients with metabolic disorders. The best available evidence for arthroscopy, a single sham-controlled RCT (n=180), showed that arthroscopic lavage with or without debridement was equivalent to placebo. The main limitations of this trial are the use of a single surgeon and enrollment of patients at a single Veterans Affairs Medical Center. No studies reported separately on patients with secondary OA of the knee. The only comparative study was an underpowered, poor-quality trial comparing viscosupplementation to arthroscopy with debridement. CONCLUSIONS: Osteoarthritis of the knee is a common condition. The three interventions reviewed in this report are widely used in the treatment of OA of the knee, yet the best available evidence does not clearly demonstrate clinical benefit. Uncertainty regarding clinical benefit can be resolved only by rigorous, multicenter RCTs. In addition, given the public health impact of OA of the knee, research on new approaches to prevention and treatment should be given high priority.
