Knee Valgus Collapse
Inward knee cave during squats or landings that raises injury risk, especially when fatigued. Hip and core strength plus landing practice help correct it.
Knee valgus collapse is inward knee cave during squats, landings, or cuts—often linked to weak hip abductors, poor trunk control, or fatigue. It raises ACL and patellofemoral stress in research, especially in female athletes and tired states.
Correct with hip and core strength, landing practice, and load management, not cueing alone.
Common questions
-
Is knee valgus always dangerous?
Small movement variability is normal; repeated large valgus under load and fatigue is the concern. Reduce load, improve hip control, and film landings when pain appears.
