About

We try to find out the effect of zoledronic acid over pain of primary knee osteoarthritis and also functional status in a period of 6 months.

Full description

This will be a double blind placebo controlled randomized clinical trial at department of rheumatology, Bangabandhu Seikh Mujib Medical University (BSMMU) from January 2023 to December 2023. Total 92 primary knee OA patients will be enrolled by following the inclusion criteria of ages 50 years and above with primary knee OA informed written consent. Then randomization will be done into group A and group B following a randomization table, each consist of 46 patients. Consecutive sampling technique will be followed. Primary knee OA will be diagnosed on the basis of ACR clinical and radiological criteria. Relevant laboratory investigations will be done. Baseline pain status will be measured by Bangla version of Western Ontario and McMaster Universities Osteoarthritis index (WOMAC), visual analog scale (VAS) and numerical rating scale (NRS) and quality of life will be measure by European quality of life scale (EQ-5D-5L). Then one group will receive single infusion of 5mg zoledronic acid and another group will receive the placebo. Each patient will be allowed take NSAIDs on requirement basis with documentation and follow non pharmacological treatment of OA. At the end of 6 months, again pain and functional status will be measured by WOMAC scale
