How different grades of chondromalacia patella affect static and dynamic balance
Official title: EFFECT OF GRADES OF CHONDROMALACIA ON STATIC AND DYNAMIC BALANCE: CROSS-SECTIONAL STUDY
Run by Cairo University · NCT07014787 · Data updated 2026-11-12
We will test whether different grades of chondromalacia patella change static and dynamic balance in adults aged 18 to 40.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18–40 with MRI-confirmed unilateral or bilateral chondromalacia (grade I–IV), BMI 19.0–29.0, symptom duration over three months, and a positive patellar grind test.
✕Probably not a fit
Patients with rheumatoid or other inflammatory arthritis, vestibular or neurological disorders, recent intra-articular knee injections (within 3 months), prior knee replacement, or those outside the age/BMI ranges are unlikely to benefit from or qualify for this protocol.

What this trial studies
This observational study will recruit 100 participants including 80 patients with MRI-confirmed chondromalacia patella (20 each for grades I–IV) and 20 healthy controls. Participants will undergo static and dynamic balance testing using the Biodex Balance System at the Faculty of Physical Therapy, Cairo University. Eligible patients are adults 18–40 years old with BMI 19.0–29.0, chronic symptoms for more than three months, and a positive patellar grind test, while those with inflammatory arthritis, vestibular or neurological disorders are excluded.
Why it matters
Potential benefit: If successful, the results could help tailor rehabilitation and fall-prevention strategies by identifying grade-specific balance deficits in people with chondromalacia.
How similar studies have gone: Previous work has reported balance impairments in people with knee osteoarthritis and patellofemoral pain, but using the Biodex to compare balance across specific chondromalacia grades is relatively novel.
