Kin325 1st Edition Lecture 5 Outline of Last Lecture I. Hip joint (Sacroiliac Joint)-functions-ligaments-musclesII. Common Hip PainOutline of Current Lecture I. Knee Joint-hinge joint-ligaments-menisci -joint capsule Current LectureKnee Joint-largest synovial joint in the body-articulations between the femur and tibia Hinge Joint-allows flexion and extension of the lower leg“Full extension” is standing -ligaments on either side that lock and stabilize the join in standing These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-articular surfaces are covered by hyaline cartilageMedial and lateral condyles on both the distal end of the femur and top of the tibia articulateLigaments -Collateral Ligaments:There are two, the medial (tibial) and lateral (fibular) ligaments, which reinforce the jointThey have an origin at the intercondylar region and insertion on the tibial ligament with the Sartorius, Gracilis, and Semitendinosus muscles…This is also known as the “Pes Anserine.”-Cruciate Ligaments: There are two, the anterior and posterior, which cross over each other on the back of the kneePrevent anterior/posterior placement of the tibia -Patella Ligament: On anterior of leg Joint Capsule-Fibrous Membrane: Reinforced by medial collateral and patellar ligaments Separated from fibular collateral ligament by fibular bursa Oblique popliteal ligament arches over the back of the capsule for posterior reinforcement -Synovial Membrane: Folds in various places to form bursaSuprapatella bursa lies just above patellaSubpopliteal recess is under popliteus tendon between lateral menisciPrepatellar bursa is just over the kneecap Deep infrapatellar bursa under patella ligamentSuperficial infrapatellar bursa sits on patellar
