Can hip exercises protect knee cartilage in osteoarthritis?
NCT ID NCT07657481
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial investigates whether adding hip strengthening exercises to a standard quadriceps program better preserves knee cartilage thickness and improves symptoms in people with knee osteoarthritis. Fifty-six adults with mild-to-moderate knee OA will be randomly assigned to one of two home exercise routines. Researchers will use ultrasound to measure cartilage changes at 1 and 3 months, alongside pain and function assessments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- home exercise program (quadriceps strengthening with or without hip abductor/adductor exercises)
- What this could lead to
- If hip exercises prove more effective, this could lead to better non-surgical treatments for knee osteoarthritis that preserve cartilage and reduce pain.
- What could go wrong
- This is a small, early-stage trial with only 56 participants, so results may not apply broadly. Exercise programs rely on patient adherence, and cartilage changes may be minimal.
