Damaged joint surfaces of all the three compartments are resurfaced with a new artificial joint. Metal components of the implant are put to a femur and tibia bone ends with or without cement. The plastic spacer is inserted between 2 metal components for wettability and smoothness. Fast track protocol is followed for surgery that makes the patient walk on day 1, climb stairs by 2-3 days and discharge by 4 days.

90% of implants survive at 15 -20 years without any complications. Recent advancements in technology such as the use of Zirconium coated (Oxinium)and crosslinking of poly are supposed to increase the longevity by another 10 years.
