CONTEXT Glucosamine and chondroitin preparations are widely touted in the lay press as remedies for osteoarthritis (OA), but uncertainty about their efficacy exists among the medical community. [] Key MethodDATA SOURCES We searched for human clinical trials in MEDLINE (1966 to June 1999) and the Cochrane Controlled Trials Register using the terms osteoarthritis, osteoarthrosis, degenerative arthritis, glucosamine, chondroitin, and glycosaminoglycans.

Figures and Tables from this paper

Structural and symptomatic efficacy of glucosamine and chondroitin in knee osteoarthritis: a comprehensive meta-analysis.

This study demonstrates the structural efficacy of glucosamine and indistinguishable symptomatic efficacies for both compounds in knee osteoarthritis and further studies are needed to investigate the relationship among time, dose, patient baseline characteristics, and structural efficacy for an accurate, disease-modifying characterization of these 2 compounds.

Glucosamine and Chondroitin Sulfate as Therapeutic Agents for Knee and Hip Osteoarthritis

Glucosamine sulfate (but not glucosamine hydrochloride) and chondroitin sulfate have small-to-moderate symptomatic efficacy in OA, although this is still debated.

Review: both glucosamine and chondroitin are effective for osteoarthritis, but the magnitude of effect is unclear

Glucosamine Long-Term Treatment and the Progression of Knee Osteoarthritis: Systematic Review of Randomized Controlled Trials

The available evidence suggests that glucosamine sulfate may be effective and safe in delaying the progression and improving the symptoms of knee OA.

Effects of glucosamine, chondroitin, or placebo in patients with osteoarthritis of hip or knee: network meta-analysis

Compared with placebo, glucosamine, chondroitin, and their combination do not reduce joint pain or have an impact on narrowing of joint space and health authorities and health insurers should not cover the costs.

Efficacy of glucosamine, chondroitin, and methylsulfonylmethane for spinal degenerative joint disease and degenerative disc disease: a systematic review.

There was little literature found to support the use of common nutritional supplements for spinal degeneration, making it difficult to determine whether clinicians should recommend them.

Chondroitin for osteoarthritis.

The benefit and harm of oral chondroitin for treating osteoarthritis compared with placebo or a comparator oral medication including, but not limited to, nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics, opioids, and glucosamine or other "herbal" medications are evaluated.

Efficacy of Chondroitin Sulfate in Patients with Knee Osteoarthritis: A Comprehensive Meta-Analysis Exploring Inconsistencies in Randomized, Placebo-Controlled Trials

This new meta-analysis suggests that CS provides a moderate benefit for pain and has a large effect on function in knee OA, however with large inconsistency.



Glucosamine sulfate in osteoarthritis of the knee.

Effect of glucosamine hydrochloride in the treatment of pain of osteoarthritis of the knee.

There was no significant difference in pain reduction between the glucosamine hydrochloride and placebo groups as measured by WOMAC, but the secondary endpoints of cumulative pain reduction as measures by daily diary and knee examination were favorable, suggesting that glucosamines hydrochlorides benefits some patients with knee OA.

[Anti-arthrosis treatments: efficacy and tolerance of chondroitin sulfates (CS 4&6)].

This study suggests that chondroitin sulfates act as structure modulators as shown by the improvement in the interarticular space visualized on the x-rays of patients treated with CS 4&6.

The neglect of glucosamine as a treatment for osteoarthritis--a personal perspective.

[Chondroitin sulfate in the treatment of gonarthrosis and coxarthrosis. 5-months result of a multicenter double-blind controlled prospective study using placebo].

It is indicated that chondroitin sulfate is useful for the treatment of osteoarthritis, both as an agent slowly effective against symptoms and to reduce the need for NSAIDs.

A systematic review of randomized controlled trials of pharmacological therapy in osteoarthritis of the hip.

NSAID trials in patients with OA of the hip appear to be weakened by a lack of standardization of case definition of OA, and also by the lack ofStandardization of outcome assessments.

Efficacy and safety of intramuscular glucosamine sulfate in osteoarthritis of the knee. A randomised, placebo-controlled, double-blind study.

Assessment of the efficacy and safety of glucosamine sulfate intramuscularly given on the same parameters found that when orally given, it is more effective than placebo and at least as effective as non-steroidal anti-inflammatory drugs in relieving osteoarthritis symptoms.
