Postinjection protocols following platelet-rich plasma administration for knee osteoarthritis: A systematic review.

Objective: Platelet-rich plasma (PRP) use in treating orthopedic conditions has increased, yet evidence of its clinical efficacy is inconsistent and limited by heterogeneity in osteoarthritis (OA) severity, PRP preparations and protocols, and clinical outcome measurement. This review aims to characterize the variations in postinjection protocols in studies assessing the clinical efficacy of PRP for knee OA.

Literature Survey: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
