Landing Biomechanics Following Fatigue in Athletes With and Without a History of Patellar Tendinopathy
An observational study of Patellar Tendinitis and Fatigue, run by University Ghent at 1 site in Belgium.
Trial summary
In this case-control study, two- and three-dimensional landing biomechanics, by means of lower limb joint angles and moments (opto-electronic system with synchronised force plate), will be compared between 30 male volleyball/basketball players with a history of patellar tendinopathy and 30 healthy controls.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Biomechanical analysisDiagnostic test
3D analysis of landing manoeuvres.
Fatigue protocolOther
A circuit of different tasks (e.g. jumping, sprinting forward and backward, side-stepping exercise) was performed to induce fatigue.
| Study group | Role | What they receive |
|---|---|---|
| History of patellar tendinopathy | Not described Receives: Diagnostic Test: Biomechanical analysis; Other: Fatigue protocol | |
| Healthy controls | Not described Receives: Diagnostic Test: Biomechanical analysis; Other: Fatigue protocol |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in landing biomechanics (kinematics and kinetics)
Trunk and lower extremity joint angles and moments will be extracted with an opto-electronic system and synchronised force plate
Measured: Immediately after fatiguing exercises

Questions about this trial
What is this clinical trial studying?
An observational study of Patellar Tendinitis and Fatigue, run by University Ghent at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Change in landing biomechanics (kinematics and kinetics) (time frame: Immediately after fatiguing exercises). 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 29 Mar 2021; AzTrials last refreshed its copy on 8 Nov 2026.
