Abstract

The aim of this study was to evaluate the efficacy of platelet rich plasma (PRP) injections on the healing of chronic patellar tendinitis. We treated 44 patients affected by chronic patellar tendinitis. Lysholm, International Knee Documentation Committee, visual analogue scale score were used for clinical evaluation before, at the end of the treatment. A statistically significant improvement in all scores was observed at the end of the PRP injections in patients with chronic patellar tendinitis. The clinical results are encouraging, indicating that PRP injections have the potential to promote the achievement of a satisfactory clinical outcome to chronic patellar tendinitis.
