New study: Platelet-Rich Plasma (PRP) Injections Delay the Need for Knee Replacement (Arthroplasty)

TOBI Faculty Dr. Diego Delgado and colleagues recently published an article in International Orthopedics.  A retrospective study and survival analysis, researchers seek to evaluate the ability of PRP injections to delay the progression of Knee OA and, thereby, delay the use of total knee arthroplasty to treat advanced knee osteoarthritis. This study looks at the outcomes from two points-of-view: the time of delay, and the percentage of patients foregoing surgery.

Patients who underwent knee replacement surgery between 2014 – 2019 and who previously had PRP injections to the affected knee were included in the retrospective study. On the contrary, patients diagnosed with knee osteoarthritis who received PRP injections with follow-up from 2014 to 2019 were included in the survival analysis. Of the 667 patients who met inclusion criteria for the study, 74% of patients in the retrospective study successfully delayed joint replacement surgery up to 18 months, and nearly 86% of the patients in the survival analysis study did not undergo joint replacement surgery within the five-year follow-up period.

Congratulations to TOBI Faculty Dr. Delgado for his contribution to this article suggesting that PRP injections may effectively delay joint replacement surgery in the treatment of knee osteoarthritis.  Access the full article here https://pubmed.ncbi.nlm.nih.gov/32621139/
