Correlation of ultrasound and magnetic resonance imaging with clinical outcome after patellar tenotomy: Prospective and retrospective studies

Abstract

Objective: To report the appearances of ultrasound (US) and magnetic resonance imaging (MRI) before and after surgery for chronic patellar tendinopathy and to correlate postoperative appearances with clinical outcome. Design: A 12-month prospective longitudinal study and a retrospective study, each part using different patients. Prospective study included clinical assessment, ultrasound, and MRI all performed before and 12 months after surgery. Retrospective study included ultrasound and clinical assessment only (i.e., no MRI) 24 to 67 months after surgery. Setting: Institutional athlete study group in Australia (Victorian Institute of Sport Tendon Study Group). Patients: In the prospective ..
