Blood loss, hospital stay do not decrease with PRP use during TKA

By Monica Jaramillo

Patients who underwent total knee arthroplasty with the use of platelet-rich plasma did not experience less blood loss or a shorter hospital stay compared with control patients, according to study results.

Researchers prospectively observed 93 patients with osteoarthritis of the knee undergoing total knee arthroplasty (TKA). Forty-six patients underwent TKA with the use of platelet-rich plasma (PRP) injection, and a control group comprising 47 patients underwent TKA without the PRP injection.
