- Jumper's knee10043237
Recruitment & Eligibility
- Status
- Recruiting
- Sex
- Not specified
- Target Recruitment
- 101
- Age 18-35 years old
- History of knee pain in patellar tendon or its patellar or tibial insertion
in association with training and competition
- Playing sports for at least 3 times a week
- Palpation tenderness to the corresponding painful area
- On ultrasound, there needs to be a fusiform tendon thickening and/or
decreased tendons structure and/or increased Doppler signal within the patellar
tendon
- VISA-P score < 80/100 points
Only age and sport frequency are applicable for the healthy volunteers
recruited. We will also perform a tendon loading test (single leg squat) and
tendon palpation and the volunteers will complete the VISA-P questionnaire to
ensure that they are asymptomatic.
- Known presence of inflammatory joint diseases (e.g. spondylarthropathy, gout
or rheumatoid arthritis) or familial hypercholesterolaemia.
- Contraindications for MRI (pregnancy, metallic implants, etc.)
- Daily use of drugs with a putative effect on the patellar tendon in the
preceding year (e.g. fluoroqinolones and statins)
- Knee surgery in the history of the index knee
- Previous patellar tendon rupture of the index knee
- Local injection therapy with corticosteroids in the preceding 12 months
- Daily exercise therapy with a minimum duration of 4 weeks in total in the
preceding 12 months
- Acute knee or patellar tendon injuries
- Inability to perform an exercise program
- Participation in other concomitant treatment programs
- Signs or symptoms of other coexisting knee pathology on physical examination
(such as joint effusion and joint line tenderness) or additional diagnostics
(Chondral lesion of the patella or trochlea on MRI or prepatellar bursitis on

- Primary Outcome Measures
Name Time Method <p>The primary outcome measure is the change in Victorian Institute of Sports<br /><br>Assessment - Patella (VISA-P) score. The VISA-P score is a simple, validated<br /><br>and reliable instrument for measuring the severity of patellar tendinopathy and<br /><br>is sensitive to small changes in symptoms. It was specifically designed for<br /><br>patellar tendinopathy, rating pain, symptoms, simple test of function and the<br /><br>ability to participate in tendon-loading sports .</p><br>
