tendon structure as determined with ultrasonographic tissue characterisation (UTC)(expressed in echo type percentages)
Achtergrond van het onderzoek
Relevance:
Despite its frequency and impact on athletic careers and in spite of decades of research, management of patellar tendinopathy remains frustrating and unpredictable for both athletes and clinicians. FSWT and RSWT appears to be a promising treatment method in patients with chronic patellar tendinopathy, referred to a sports medicine department after other conservative treatments had failed.
However, it remains unknown what effect FSWT and RSWT have on the tendon structure. To better understand the effect of FSWT and RSWT, it is important to evaluate the effect on the tendon structure in healthy subjects and patients with patellar tendinopathy.
Objective:
The aim of the study is to evaluate the effect of FSWT and RSWT on the tendon structure in healthy subjects and in patients with patellar tendinopathy.
Study design:
A randomized controlled pilot study using a 4 group repeated measures design. Groups are divided in FSWT group with PT patients (N=15), FSWT group with healthy subjects (N=15), RSWT group with PT patients (N=15) and RSWT group with healthy subjects (N=15). A shockwave treatment period of 2 weeks (3 treatments with a 1 week interval) will be applied and a 12 week follow-up with exercise therapy for PT patients only. Results are analyzed with a multilevel analysis
Main study parameter:
Tendon structure in echotype percentages determined by UTC.

Onderzoeksopzet
1. Before and after first treatment (healthy and PT group)
2. Before and after second treatment (healthy and PT group)
3. Before and after third treatment (healthy and PT group)
4. 1 week after final treatment (healthy and PT group
5. 6 weeks after final treatment (PT group only)
6. 12 weeks after final treatment (PT group only)
Onderzoeksproduct en/of interventie
Patients and subjects receive three sessions of either focused shockwave therapy (FSWT) or radial shockwave therapy (RSWT) with an one week interval. Patellar tendinopathy patient receive shockwave therapy in combination with eccentric decline squat training.

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
Male and female subjects with the following criteria are eligible for inclusion in patellar tendinopathy (PT) subject group:
• History of knee pain in patellar tendon or its patellar or tibial insertion in connection with training and competition
• Symptoms for over three months (to exclude acute inflammatory tendon problems and de novo partial ruptures)
• Age 18-45 years old (to reduce the chance of other osteochondrotic diseases like Sinding-Larsen-Johanson, Osgood-Schlatter and osteoarthrosis)
• Palpation tenderness to the corresponding painful area
• Degenerative tendon changes determined by a regular ultrasound echo
• VISA-P score < 80
Male and female subjects with the following criteria are eligible for inclusion in healthy subject group:
• Age 18-45 years old
• VISA-P score of 95 or higher
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
Subjects must not be included in the PT subjects group if one of the following applies:
• acute knee or patellar tendon injuries
• chronic knee joint diseases
• signs or symptoms of other coexisting knee pathology
• contraindications for SWT (pregnancy, malignancy, coagulopathy)
• knee surgery or injection therapy with corticosteroids in the last preceding three months
• daily use of drugs with a putative effect on patellar tendinopathy in the last year (e.g. non-steroid anti-inflammatory drugs, fluorchinolones) or actual use of anticoagulants
• Allergy or intolerance for paracetamol
Subjects must not be included in the healthy subjects group if one of the following applies:
