Document Summary
Chapter 8 the lower extremity: the knee, ankle, and foot: the knee joint. Biased is very lateral; you want strong vastus medius. If you have swelling it"s usually supra patella. 12: lcl: not attached to lateral meniscus but the. Concave vs convex rule: when is it concave on convex, when is it convex on concave, capsular pattern: flexion > extension, open pack position: 30 degrees of flexion, close pack position: full knee extension. Open pack position: loosest the joint will be at; test acl in this position (lachman"s procedure). Meniscus: menisci: medial and lateral, they sit on the tibial plateau medially and laterally, lateral forms an incomplete circle, medial forms a large letter c, Anchored to the mcl and semimembranosus posteriorly, Women are valgus and women athletes are more likely to tear acl. Screw home mechanism: the tibia externally rotates about 20 degrees on the fixed femur; femur internally rotates; terminal rotation of the knee.
