Background: Osteoarthritis (OA) is a major source of disability owing to pain and loss of function. Intra-articular (IA) injection is the last nonoperative modality that can be used. We compared the efficacy of IA steroids and prolotherapy for relieving pain in patients of knee OA. Materials and Methods: We conducted a randomized, double-blind comparative study on 56 patients of OA knee assigned into two groups: steroid and prolotherapy group. Injections were given at 0, 1, and 2 months. During 6-month follow-up, patients were evaluated for pain relief by visual analog scale (VAS) score, quality of life (QOL) score, and requirement of rescue analgesic. Results: At baseline, mean VAS score of prolotherapy group (6.71 ± 0.94) and steroid group (6.36 ± 0.99) were comparable (P = 0.166). After 6 months, mean VAS score in prolotherapy group was 4.07 ± 1.44 as compared to 3.14 ± 0.89 in steroid group, and difference was statistically significant (P = 0.009). Furthermore, at baseline, QOL score of prolotherapy group (81.75 ± 4.69) and steroid group (79.29 ± 3.89) were comparable. After 6 months, it was found to be 70.43 ± 4.97 in prolotherapy group and 67.36 ± 2.74 in steroid group, the difference being highly significant (P = 0.007). Number of patients requiring rescue analgesia (P = 0.280) and the mean number of doses of rescue analgesic consumed (P = 0.538), both were slightly higher in prolotherapy group. Conclusion: Intra-articular steroid was better than prolotherapy in relieving pain of OA knee.
