Document Summary
Joint type: anatomically = synovial, functionally = hinge, physiologically = gliding, rotation (locking) Articulations: femoral (lateral and medial) condyles & menisci, tibial plateau & menisci, patella & femur, patellofemoral groove, tibial plateau, tibial spine is the bony bump. Increased distance on the medial side of the knee is important for locking: lateral is more o shaped and medial more c shaped. Ligaments: medial collateral (mcl, short inner, long outer fibres. Injured more frequently than lcl: extracapsule structure (not deep within the joint) Menisci: fibrocartilage, medial and lateral, attached to tibial plateau, attached to capsule by coronary ligaments, provides cushioning & stability. Inner part of meniscus is not attached to the bone at all so there is no blood supply to it (it wont be able to heal itself) Capsule: extensive & redundant- to allow for movement, swelling usually appears on the front of the knee, resists hyperextension, provides rotational stability.
