1.Total knee replacement: The procedure of a total knee replacement involves replacing the joint surface at the end of your thigh bone and at the top of your shin bone. These are one of the most common and successful treatments. Some surgeons use a natural palette and sometimes a smooth plastic dome is used to cover the surface of the kneecap.

2.Partial or Unicompartmental knee replacement: In a partial or unicompartmental knee replacement, only a portion of the knee is surfaced. This is an alternative procedure to total knee replacement for those whose pain or disease is limited to certain areas. This treatment takes lesser time and is done through a smaller incision.
