Presentation
Anterior and medial joint line pain. No history of trauma.
Patient Data









Sagittal PD and PD fat sat images of the left and right knees respectively demonstrate thickened and high signal changes in the proximal fibres of the patellar tendon.
Case Discussion
Jumper's knee, also known as chronic patellar tendinitis is characterised by chronic anterior knee pain, localised mostly at the site of patellar insertion of the patellar tendon and is frequently seen in athletes. Plain films are useful to localise the position of the patella, associated pathologies and intratendinous calcifications. US and MRI are useful to measure the thickness of the tendon. MRI is the best modality to diagnose this condition. Fat-saturated MR images demonstrate high signal changes within the tendon and also detect partial tears of the tendons. Conservative treatment options include exercises and Extracorporeal Shockwave Therapy (ESWT). Surgery is reserved for patients who do not respond to conservative treatment options.
