Squat biomechanics: Knees in or out? With Raphael Bender

• Factors influencing squat biomechanics
• Are weak glutes to blame for knees going in (valgus)?
• The mechanism of ACL injury in athletes
• Components of skilled movement

Resources mentioned during the session:

• Knee valgus in squatting does not predict future ACL injury here
• People with knee osteoarthritis have more cartilage degeneration on the medial knee compartment, regardless of valgus or varus alignment here
• Women have more knee abduction in weight-bearing activities here
• Conflicting and poor quality evidence of a relationship between hip muscle strength and knee valgus here and here
• Less ankle dorsiflexion is associated with more knee valgus here
• Paralyzing the gluteus medius doesn’t change the Trendelenburg test here
• The ITB stores elastic energy during running here
• Humans make near-optimal adjustments of control to initial body configuration in vertical squat jumping here
