Platelet-rich plasma injections delay the need for knee arthroplasty: a retrospective study and survival analysis
Patients who had knee osteoarthritis and received PRP injections were evaluated for any benefit in delaying a total knee arthroplasty, also known as total knee replacement. The retrospective analysis of 667 patients showed that the knee replacement was delayed on average of more than 1.5 years, with a median value of 5.3 years. This was correlated to the severity of arthritis, age of the patient, route of administration, and PRP cycles.
The Takeaway: For those with arthritis in the knees who are looking to avoid a knee replacement, receiving PRP injections into the knee might just postpone the need for surgery, but this will depend on how severe your knee arthritis is at the time of injections, what age you are when starting PRP treatments, along with injection frequency, techniques and methods.
