Fifteen patients who underwent PRP injections for symptomatic grade 2 meniscal lesions were included in the study.
All injections were performed using ultrasound guidance into the degenerated menisci. Patients were assessed with a Lysholm score and magnetic resonance imaging (MRI) before the injection and after an average follow-up of 32 months.
T2-weighted MRI images were evaluated on the sagittal plane by two authors in a double-blind manner.
