Partial (unicompartmental) and Total Knee Replacement
The knee is a complex hinge joint between the thigh bone (femur) and shin bone (tibia).
The knee joint also includes the patello-femoral joint between the kneecap (patella) and the trochlea (groove) on the front of the femur. Ligaments can be likened to pieces of string whose purpose is to control and prevent excessive movement of joints. Ligaments are made of strong connective tissue (collagen).
There are two main groups of ligaments in the knee that connect the femur to the tibia, the collateral ligaments and the cruciate ligaments.The two main groups of ligaments are called the collateral ligaments, which are at the sides of the knee, and the cruciate ligaments in the centre of the knee.
The medial and lateral collateral ligaments [MCL and LCL] lie outside the capsule of the knee joint on the inside (medial) and outside (lateral) of the knee respectively. They mainly control excessive sideways motion.
