Ultrasound-guided Platelet-rich Plasma Injection for Chronic Patellar Tendinopathy: A Case Report

Traumatic and overuse tendinopathies are common problems encountered in musculoskeletal practice. There are various treatment methods used to treat these conditions, most of which lack sufficient evidence to recommend their use W. Platelet-rich plasma (PRP) injection is a relatively new treatment method, which has shown promising results so far [2,3]. It is an autologous concentration of platelets in a small volume of plasma and is rich in several growth factors that promote tendon healing [4]. Patellar tendinopathy is a chronic condition seen in many sports, particularly in jumping sports [5]. A few case series reported symptom reductions in patients treated with PRP for patellar tendinopathy [5,6] The injection technique used in these studies is based on surface anatomical landmarks. We report a case of refractory patellar tendinopathy treated with targeted ultrasound-guided PRP injection with satisfactory results and discuss the potential advantages of this technique.
