1Safety of anti-osteoarthritis medicationsSystematische ÜbersichtCited 6×n=22,938 · very large study2025
This SR confirms previous evidence on the safety of anti-OA medications from meta-analyses of phase 3 RCTs.
Honvo G et al. · Drugs (2025)
This SR confirms previous evidence on the safety of anti-OA medications from meta-analyses of phase 3 RCTs.
Beyond the evidence here reported, the limitations of this research highlight the urgent need of a reporting guideline for post-marketing safety surveillance studies.
Importantly, real-life safety surveillance of anti-OA medications should be strengthened with large cohort studies with control groups, and results should be disaggregated by disease populations for drugs common to several conditions.

Highest gastrointestinal complications were reported for diclofenac (odds ratio (OR) = 4.77 (3.94, 5.76)) and lowest for total knee replacement (HR = 0.6 (0.49, 0.75)).
Ibuprofen had the highest renal complications (OR = 2.32 (1.45, 3.71)), whereas celecoxib had the highest cardiovascular risk (OR = 2.26 (1, 5.1)) and lowest was for tramadol (RR = 1.1 (0.87, 1.4)).
Results show that medical management of hip and knee OA, particularly with non-steroidal anti-inflammatory drugs, may carry higher mortality compared to surgery.
Further studies are needed to evaluate the effect of glucosamine on knee function and joint preservation, as well as to evaluate the combined effect with other components, such as chondroitin.
Ogata T et al. · Clinical rheumatology (2018)
A newly established knee OA scale, the Japanese Knee Osteoarthritis Measure (JKOM), is commonly used in Japan.
Although the number of subjects was small, the JKOM meta-analysis indicated that glucosamine is superior to a placebo in alleviating knee OA symptoms.
Given this, we concluded that glucosamine has the potential to alleviate knee OA pain.
