About this study
Patellar tendinopathy (PT) is a commonly used term for the clinical manifestation of patellar tendon pain and functional limitation with multifactorial etiology. It occurs in both athletes and general population in all age groups. It is often characterized as an overuse injury resulting from chronic failure of the healing response that is not strictly linked to inflammatory or degenerative processes.
Read the detailed description
Once enrolled, participants were examined by a physiotherapist, and received the first application of ESWT (week 0). At weekly intervals, they received three more applications and on the day of the last application (week 3), a control clinical examination was performed. In the 12th-week follow-up after the last application week 15), a final examination including joint position sense, balance and kinesiophobia evaluation was performed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Extracorporeal Shockwave TherapyDevice
The low-energy focused ESWT was applied using the BTL-6000 FSWT device with piezoelectric generator and a coupling pad which modulates penetration depth to 0-35 mm. The setting was chosen based on ISMST guidelines (https://shockwavether apy.org). Energy flux density varied between 0.14 and 0.18 mJ/ mm2 due to patient tolerance, frequency was set at 8 Hz. A total of 2000 shocks were applied semi-statically to the most defined pathological area in the patellar tendon followed by2000 shocks dynamically to the quadriceps muscle.

Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Digital inclinometer (time frame: 4 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Sep 2026.
