PHTY100 Lecture 4: topic 4
Document Summary
In full extension knee is locked no muscle effort required to maintain full extension: maximum contact between joint surfaces, tibial tubercles lodged in the intercondylar notch, ligaments tense stable joint position (cid:858)close packed position(cid:859) Increase contact area at the tibiofemoral joint reduces stress at the joint surfaces: after meniscectomy dramatic increase stress in joint (2 x at femur, 6 - 7 x at tibia) Attachments of the meniscus common to both: coronary ligaments (attachment to internal surface of capsule, patellomeniscal ligaments (anterior capsular thickenings, transverse ligament. Additional attachments of medial meniscus: medial collateral lig, anterior and posterior cruciate ligs, semimembranosus. Additional attachments of lateral meniscus: posterior cruciate lig, medial femoral condyle via meniscofemoral ligs, popliteus. 4. 1 identify and classify the bones of the thigh and leg: femur, tibia, fibula. The longest and strongest bone in the body. Transmits body weight from the ilium to the upper end of the tibia.
