Knee pain diagnosis: could a 5-Minute exam beat an MRI?
NCT ID NCT06971601
First seen Jun 25, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This study is testing whether a set of five simple physical exam maneuvers can accurately diagnose infrapatellar fat pad impingement, a common cause of front knee pain. Researchers will compare the results of these clinical tests to MRI scans in 50 adults with anterior knee pain. If the tests prove reliable, it could offer a faster, cheaper, and more accessible way to diagnose this condition without the need for expensive imaging.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- standardized clinical provocation tests
- What this could lead to
- If successful, this could provide doctors with a reliable, low-cost way to diagnose a common cause of knee pain without needing an MRI.
- What could go wrong
- This is a small, early-stage observational study (50 people). The clinical tests may not prove accurate enough to replace MRI, and results may not apply to all patients.

Who is studied
Adults aged 18 to 70 years experiencing anterior knee pain (AKP) rated ≥3/10 for at least 4 weeks will be eligible. Patients will be recruited from the department of orthopedic and trauma at Hôpital Paris-Est Val de Marne (Saint-Maurice), including both postoperative cases (e.g., post-arthroscopy) and non-surgical patients referred for expert consultation regarding persistent or unexplained anterior knee pain.
