Intraarticular Platelet-rich Plasma Injections Versus Corticosteroid Injections in Primary Knee Osteoarthritis

Aim: To study and compare the clinical effects of platelet-rich plasma (PRP) injections and intra-articular (IA) corticosteroid injections in patients with primary osteoarthritis (OA) of the knee. This study aims to demonstrate this by using the Oxford Knee Score and Western Ontario and McMaster Universities Arthritis Index (WOMAC) to illustrate quantifiable difference between the two treatment modalities. Patient satisfaction will be compared by utilizing the Short-Form Survey-12 (SF-12) Score. Our null hypothesis states that intra-articular PRP injections is more beneficial in the long-term treatment of primary OA of the knee.
