Abstract:
Osteoarthritis (OA) affects the entire joint structure. The most injured joints are the hands, knees, and hips. OA is a common disease all over the world, and a cause of disability in the elderly; hence, medicine is facing a steady challenge to find effective therapeutics to relieve the pain, improving symptoms for a better quality of life for patients.
Purpose:
To compare the results, in the recent literature, of intra-articular injection of platelet-rich plasma (PRP) and corticosteroids (CSs) in osteoarthritic knees at early and mid-term postinjection.
Methods:
A PubMed and CENTRAL (Cochrane Central Register of Controlled Trials) database search was performed. Initial screening yielded 108 randomized controlled trials, 17 results, and 17 others were added after updates. The final review includes nine randomized control trials, with outcome evaluating of knee OA by Western Ontario and McMaster Universities Arthritis Osteoarthritis Index, Knee Injury and Osteoarthritis Outcome Scale Index, and Visual Analog Scale.
Results:
PRP and CS intra-articular injections both are safe and effective treatments in knee OA for alleviating pain, and improving symptoms. It seems that PRP injections have prolonged and shown better improvement in some studies. However, the results do not prefer one method over the other.
Conclusion:
Up till now, it is not easy to draw firm conclusions about prioritizing PRP or CS injections for knee OA treatment due to the limitation of this review.
