Treatment
Medications
Acetaminophen
A randomized controlled trial comparing acetaminophen to ibuprofen in x-ray proven mild to moderate osteoarthritis of the hip or knee found that equal benefit.[1] However, acetaminophen at a dose of 4 grams per day can increase liver function tests.[2]
Supplements
Chondroitin
A meta-analysis of randomized controlled trials found no benefit from chondroitin.[3]
Glucosamine
A molecule derived from glucosamine is used by the body to make some of the components of cartilage and synovial fluid. Supplemental glucosamine may improve symptoms of OA and delay its progression.[4] However, a large study suggests that glucosamine is not effective in treating OA of the knee.[5] A subsequent meta-analysis that includes this trial concluded that glucosamine hydrochloride is not effective and that the effect of glucosamine sulfate is uncertain.[6]
