Clinical Eficacy of Extracorporeal Shock Wave Therapy on Patellar Tendinitis
China38 participantsStarted 2026-03-01
Plain-language summary
This study is a randomized controlled trial. Patients diagnosed with patellar tendinitis and meeting the criteria for shockwave therapy were included. Relevant clinical data and assessments were collected upon enrollment and after obtaining informed consent. Randomization was performed using a random number table: the experimental and control groups. Based on the group assignments, the experimental group received either patellar tendon combined with fascial therapy coordinated centre point shock wave treatment, while the control group received only shockwave therapy for the patellar tendon. The treatments were performed by a rehabilitation therapist with extensive clinical experience. Data on participant pain and knee joint function were collected using the Visual Analogue Scale (VAS) and the Lysholm Knee Scoring System at baseline and on the day following completion of all treatments. Data on the thickness of the patellar tendon on the affected side of the knee were collected using a portable musculoskeletal ultrasound imaging system. Follow-up assessments and data collection on pain and knee joint function were conducted using the VAS and Lysholm Knee Scoring Scale one month and three months after the completion of all treatments to compare changes before and after treatment and to evaluate whether patellar tendon combined with fascial therapy coordinated centre point shock wave therapy has superior short-term and medium-term maintenance efficacy for patellar tendinitis compared with simple patellar tendon shock wave therapy.

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
