Intraoperative application Platelet rich fibrin, postoperative injections OF PRP or microfracture only for osteochondral lesions of the knee: a five-year retrospective evaluation
Vol 30, Issue 4S1, 2016
Abstract
Cartilage lesions are the most common cause of chronic knee pain. Micro-fracturing is reliable, effective, easy to perform and inexpensive. We propose a novel approach to cartilage lesions where microfractures are performed contextually to intra-operative or post-operative administration of platelet concentrates. We retrospectively evaluate 48 patients divided in 3 groups. Group 1: 15 patients underwent microfractures and intraoperative administration of PRF (PRF group); group 2: 16 microfractures and postoperative injections of PRP (PRP group); group 3: 17 patients with isolated microfractures (Microfractures group). Clinical scores (IKDC, VAS pain) were administered at 2 and 5 years postoperative and MRI was performed to evaluate the lesions of patients according to the MOCART criteria (2006). Patients treated with platelet concentrates achieved better clinical results compared to patients treated with microfracture only. The PRF group showed better results than the PRP group at 2 years, with loss of significance at 5 years. At MOCART score, PRF group obtained better results earlier than the other two groups.
