Here is a bit of a cheat sheet to help you decifer some of the terms thrown about by surgeons.........
Medial = inside (of leg)
Lateral= outside (of leg)
Inferior = below
Superior = above
Quadriceps = front thigh muscles
Hamstring= back thigh muscles
Patella = kneecap
Femur = thigh bone
Tibia = Shin bone, main weight-bearing bone
Fibula = smaller of the two bones in the lower leg.
Articular = of the joint
Intra-articular = inside the joint
Extra-articular = outside the joint
Medial compartment = inside half of the knee joint
Lateral compartment = outside half of the knee joint
Patellofemoral joint = The joint where the kneecap slides up and down in the groove of the thigh bone
Meniscus = Shock absorbing structure between femur and tibia (often mistakenly called "cartilage")
Cartilage = smooth covering of joint surfaces. Allows painfree movement
Plenty to learn isn't there!
