Total Knee Replacement
When a knee is severely damaged by arthritis or injury, it may be prevented from moving normally and require a surgical repair. A knee replacement involves removing the damaged areas of the knee and replacing with new components and restoring the function and surface of the knee.
During the procedure, the worn surfaces at the end of the thighbone are removed using special instruments. The bone is then shaped to prepare for the new covering. Then the top of the shinbone (tibia) is prepared in a similar way. The worn surface is removed and a new metal surface is placed on top of the remaining bone. In between the two implant surfaces Dr. LaReau will add a new spacer or shock absorber between the smooth metal coverings. These components are fixed to the bone surface based on the selection of the surgeon. Towards the end of the surgery after the implants have been secured, Dr. LaReau will move your knee joint to make sure it moves normally and to confirm it works in tandem with the supporting muscles and ligament tissues.
