Document Summary
All have general features, but some also have unique structural features, abilities, and weaknesses. 5 main synovial joints: knee, shoulder, elbow, hip. Consists of 3 joints surround by single cavity: femoropatellar joint, plane joint, allows gliding motion during knee flexion, lateral joint, medial joint, lateral and medial joints together are called tibiofemoral joint. Joint between femoral condyles and lateral and medial menisci of tibia: hinge joint that allows flexion, extension, and some rotation when knee partly flexed. Anteriorly, quad tendon gives rise to 3 broad ligaments that run from patella to tibia: medial and lateral patellar retinacula that flank the patellar ligament. Tap patellar ligament to test knee-jerk reflex. At least 12 bursae associated with knee joint. Capsular, extracapsular, or intracapsular ligaments act to stabilize knee. Capsular and extracapsular help prevent hyperextension: fibular and tibial collateral ligaments: prevent rotation when knee is extended, oblique popliteal ligament: stabilizes posterior knee joint, arcuate popliteal ligament: reinforces joint capsule posteriorly.
