Platelet-rich plasma improves pain + quality of life in knee osteoarthritis at 6 months .
Does intra articular platelet rich plasma injection improve function, pain and quality of life in patients with osteoarthritis of the knee? A randomized clinical trial
Orthop Rev (Pavia). 2014 Sep 18;6(3):540565 patients with knee osteoarthritis were randomized to receive intraarticular platelet-rich plasma (PRP) injections with exercise or exercise alone. The purpose of this randomized controlled trial was to determine the effect of PRP injections on pain, function, stiffness, and quality of life 6 months after treatment. The results displayed significantly greater improvements in WOMAC total and pain scores, and in the mental and physical domains of the SF-36 (quality of life), when compared to the control group at 6 months. Patients in the PRP group were found to consume significantly more acetaminophen during the study period.
