Platelet-Rich Plasma in Hemophilic Arthropathy of the Knee

Key clinical point: A single intra-articular injection of platelet-rich plasma showed better clinical outcomes than did weekly injections of hyaluronic acid in patients with hemophilic arthropathy of the knee.

Major finding: Pain and function scores were significantly lower in patients administered platelet-rich plasma versus hyaluronic acid at 6 months (P less than .05).

Study details: An open-label comparison study of 22 patients with hemophilia A.

Disclosures: The study was supported by grant funding from Tri-Service General Hospital in Taiwan. Three of the authors reported receiving research grants from Shire.
