Why This Matters Clinically

Knee valgus during landing, squatting, and single-leg loading is produced by a combination of hip abductor weakness (allowing ipsilateral pelvic drop and femoral adduction), hip internal rotator tightness or dominance (excessive femoral internal rotation), and foot pronation (forcing tibial internal rotation and knee valgus from below). Addressing knee valgus requires exercises targeting all three contributing factors — not merely quadriceps strengthening, which is the most commonly prescribed but least targeted intervention.

Exercise Progression

Glute-focused squatting: Wide-stance squat with band around the knees — press the knees out against the band throughout the movement. This trains the hip abductors and external rotators in the functional squat position that most commonly shows valgus collapse. Cue: "knees over the second toe." Begin with bodyweight, progress to goblet squat, then to back squat with the same band and cue. 3×12–15.

Single-leg squat with hip control: Stand on one leg, slowly squat to 60–70° of knee flexion while maintaining the knee tracking over the second toe. Place a dowel along the shin to provide feedback about knee tracking. The gluteus medius must eccentrically control the femur through the entire descent. 3×8–10 each leg.

Lateral band walk with knee tracking: Resistance band around the ankles or knees, lateral stepping with specific focus on maintaining knee alignment over the foot throughout the step. Avoid the trunk-sway compensation. 15 steps each direction, 3 sets.

Step-down with valgus correction: Stand on a step, slowly lower the non-stance heel toward the floor under control, maintaining the stance knee directly over the second toe. The eccentric demand of the step-down phase specifically trains valgus control under load. 10 repetitions each leg, 3 sets.

The foot-knee-hip chain: Knee valgus cannot be fully corrected by hip exercises alone if the foot is pronating and driving tibial internal rotation from below. Assess the longitudinal arch during single-leg squat — a collapsing medial arch alongside knee valgus indicates that foot intrinsic strengthening and arch control training must be included alongside hip-focused work. Orthotics may temporarily reduce the foot pronation contribution while the active correction capacity is being built.

Programming Guidelines

Train 3× weekly with 48-hour recovery between sessions. Begin at the level where movement quality is excellent and symptoms are 0–2/10. Progress load, range, or complexity only when the current level is performed without compensation across three consecutive sessions. Allow 8–12 weeks for functional strength to meaningfully improve in a rehabilitation context.
