|Knee Replacement Components
(Zimmer Biomet Orthopedics)
Knee replacement surgery involves replacing some or all of the components of the knee joint with a synthetic implant, to repair the damaged weight-bearing surfaces that are causing pain. A total knee replacement surgery replaces all three compartments of the diseased knee joint. A partial knee replacement involves an implant in just one or two compartments of the knee, retaining any undamaged parts. While there are non-surgical and surgical interventions short of knee replacement which will often provide temporary relief, the long-term resolution to most knee degeneration will be joint replacement.
There are several different implant designs (see: total implants | partial implants) but each will offer renewed stability and movement. Overall, there are two main benefits to be gained from knee replacement surgery: (1) elimination of pain and (2) improved range of motion. Of all possible surgical interventions, total knee replacement offers the greatest quality of life improvement. The procedure has a high rate of success.
