Objective: To assess the efficacy of intra-articular PRP injections in patients with knee osteoarthritis. Study Design: Cross Sectional. Setting: Orthopedic Department of Mardan Medical Complex. Period: 13th August to 14th December 2023. Methods: Involving 50 diagnosed osteoarthritis patients at demographic data, grades of osteoarthritis, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded pre-treatment. Patients received PRP injections at three intervals, and post-treatment WOMAC scores were assessed. Statistical analysis included mean, standard deviations, and a paired t-test. Results: The study comprised 66% female patients, with a mean age of 50.08±5.82 and mean BMI of 27.16±3.53. Regarding grades of osteoarthritis, grade 1, grade 2 and grade 3 comprised of n=14(28%), 19(38%), 17(34%) respectively PRP treatment significantly reduced WOMAC scores from a pre-treatment mean of 56.62±5.70 to 27.54±4.79 (p < 0.001). Conclusion: The significant reduction in WOMAC scores post-treatment suggests that intra-articular PRP injections may serve as a valuable intervention in the short term management of knee osteoarthritis.
