- Sex
- All
- Target Recruitment
- 70
Patients (aged 18-40 years) with a history of chronic knee pain in the proximal section of the patella or its patellar insertion in connection with training or competition will be recruited for the main study. Further inclusion criteria contain palpation tenderness, VISA-P score smaller than 80 and ultrasound characteristics of a tendon in a degenerative phase (tendon thickening; hypoechoic zones). Clinical symptoms of patellar tendinopathy patients have to last since at least three month to be classified as chronic.
Addition 3.10.2017

Exclusion criteria contain acute herniated discs and thrombosis, acute inflammatory disorders of the musculoskeletal system, gall stones, implants, acute surgeries, hernia, acute megrim, lager-area wounds, rheumatoid arthritis, epilepsy, multiple sclerosis, stroke, active arthrosis, osteoporosis fractures, pregnancy, joint implants, diabetes mellitus type II, cardiac pacemaker, tumors, uncontrolled angina pectoris, not monitored hypertension, cardiovascular disease, valvular aortic stenosis, cardiomyopathy, cochlear, otologic, or ear implant, insulin or infusion pump, defibrillator, any implant held in place by a magnet, tissue expanders (plastic surgery), implanted catheter, clamp, clips, valves, or other metal, tattoos or permanent makeup above shoulders, piercings, shrapnel or metal fragments, ever had metal removed from eye, ever worked as a metal worker, eye lenses, claustrophobia, acute knee or patellar tendon injuries, chronic joint diseases, signs or symptoms of other coexisting knee pathologies, knee surgery, injection of any kind in the patellar tendon in the preceding three months, current use of anticoagulants, corticosterois injections within 12 months.
Study & Design
- Study Type
- interventional
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Primary clinical outcomes are:<br>- The VISA-P score<br>- The patellar tendon thickness<br>- The neovascularization in the tendon<br>- Tendon hypoechoic areas<br><br>Variables will be measured before and after the intervention period and after a 6 months foollow-up.
- Secondary Outcome Measures
Name Time Method Additionally, secondary outcomes contain the reduction of PT CSAs and increase in PT stiffness and knee extensor strength due to the vibration intervention.
