Knee pain in young athletes linked to hip and core weakness
NCT ID NCT07326046
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 2 times
Summary
This completed study looked at 75 elite teen track-and-field athletes, half with patellofemoral pain syndrome (PFPS) and half without. Researchers measured hip flexibility, core endurance, and knee alignment to see what factors are linked to knee pain. They found that athletes with PFPS had tighter hips, weaker core muscles, and poorer knee alignment, suggesting knee pain is about more than just the knee itself.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help identify key physical factors that contribute to knee pain in young athletes, guiding better prevention and rehabilitation strategies.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly lead to a new therapy. The findings may not apply to non-athletes or older populations.
