BEHAVIORAL CHARACTERISTICS OF STRUCTURES AROUND THE KNEE
STABILIZING ROLE OF THE ANTERIOR CRUCIATE LIGAMENT
HEAT SENSITIVE VIEWS OF THE ANTERIOR CRUCIATE IN FLEXION
STABILIZING ROLE OF THE POSTERIOR CRUCIATE LIGAMENT
HEAT SENSITIVE VIEW OF THE POSTERIOR CRUCIATE IN FLEXION AND EXTENSION
NORMAL KNEE MOTION KNEE FLEXION-EXTENSION takes place between the bottom of the femur and the top of the menisci. TWISTING MOTION takes place between the bottom of the menisci and the tibia.
MENISCUS OF THE KNEE Purpose: Equalize weight distribution across the knee joint. Shock absorption.
Coronary Ligament Medial is tighter than the lateral. Thus, there is less mobility medially.
MENISCAL INJURY Medial Meniscus: excessive external rotation of the tibia. Lateral Meniscus: excessive flexion of the knee.
MECHANISMS OF INJURY • VALGUS • VARUS • HYPEREXTENSION • HYPERFLEXION • INTERNAL ROTATION • EXTERNAL ROTATION
X VALGUS Distal bone of the joint moves away from midline of the body.
Medial Support Complex Not Shown: Quads Medial Head of Gastrocnemius Medial Hamstrings
X VARUS Distal bone of the joint moves towards the midline of the body
Lateral Support Complex Not Shown: Iliotibial Band Biceps Femoris M. Poplitius Tendon Head of the Gastrocnemius
