Glucosamine may be effective in treating and possibly slowing the progression of Osteoarthritis (OA). It is believed Glucosamine supplements may help to stop cartilage breakdown, build cartilage and decrease swelling.


The objective of this study was glucosamine sulfate versus combination of glucosamine sulfate and Non-Steroidal anti-inflammatory drugs (NSAID) in mild to moderate knee osteoarthritis.


Subjects were randomly recruited from Rheumatology outpatient department after a diagnosis of mild or moderate Osteoarthritis. Study tools like patient data collection form, Western Ontario McMaster Universities Arthritis index (WOMAC) of Osteoarthritis questionnaires and Visual Analog Scale (VAS) were used.


After 12 weeks, WOMAC total score the result showed that the significant mean difference between the group A and Group B treatment (P < 0.01), with a combination of GS and NSAIDs reducing VAS pain scores. Thus, it is found that Group B treatments over 4 and 12 weeks produced improved WOMAC and VAS grades.


Study results may suggest that the Glucosamine Sulfate has a carryover effect like Disease modifying agents. Long-term treatment of Glucosamine Sulfate may reduce the dependence of NSAIDs usage and delay the disease progression. Thereby we can reduce the NSAIDs side effects and improve the patient's quality of life.
