PT 5131 Lecture Notes - Anterior Cruciate Ligament Injury, Knee Bursae, Genu Valgum
Document Summary
Also causes patella to track laterally: can be increased by: Laterally positioned tibial tuberosity: angle between femur and tibial shafts, estimated using q-angle, or measured using goniometer, roughly 170 -175 , genu valgum: Like having tibia abducted, with respect to femur. Knees in, ankles out: genu varum: Knee joint: modified hinge joint (bicondyloid joint, combines both rolling and gliding. Flexion/extension, internal/external rotation (only occur when knee is: minimal amount of anterior/posterior gliding and medial/lateral gliding. Dependent upon laxity of ligaments, capsule, and muscles: when knee is under stress we can distract (pull apart) or compress (push together) the knee joint, varus stress/force: bend inward. Varus force is when the distal end of a bone or joint moves medial in relation to the proximal end of a bone or joint. Pressure applied at medial aspect of knee. Cause tear in lcl: valgus stress/force: bend outward.
