A partial knee replacement (or unicompartmental knee replacement) replaces one side of the knee with a metal and plastic implant.

 

Knee replacement and the concept of compartments

Where the bones articulate in the knee is called a 'compartment' - the two articulations of tibia and femur are called the medial and lateral compartments, while the articulation of patella and femur are called the patellofemoral compartment. Replacing the joint of any of these compartments is called a 'partial' or 'uni-compartmental' knee replacement.
