Total Knee Replacement
What is a total knee replacement (TKR)?
Your surgeon may also replace your patella if there is significant wear, and if your patella bone is large enough. A TKR is done to restore motion and function to the knee, enabling patients to return to an active lifestyle.
There is a fine balance between a stable and functional knee and one that is too tight or unstable. Regardless of the technique, TKR can correct both varus (bowing of your knees) or valgus (knock knees) deformities, improve knee extension (straightening) and flexion (bending), as well as significantly improve your pain and daily function.
Robot arm-assisted knee replacement (Makoplasty®)
With Makoplasty®, further intra-operative assessments are done to ensure that the CT scans correctly reflect reality. The knee will be appropriately stressed during the surgery as needed, imitating everyday movements, to examine the placement and fit of the implants in the knee.
Another added advantage of a robot arm-assisted knee replacement is the ability to test different implants of varying sizes and only having to make microadjustments where necessary. The computer software advises on an optimal implant position for the patient to achieve good stability and movement. Once satisfied with the implant size and position, the surgeon will then proceed to make the bone cuts to place the implants in the knee.
Makoplasty® is also programmed to enhance the precision of the bone cuts made, as well as to prevent collateral injury to the adjacent soft tissues. Robot arm-assisted procedures have taken the guesswork out of complex operations such as these, resulting in satisfied patients and successful surgeries.
How long does the surgery take?
At Orion Orthopaedic Surgery, patients are given injections around the knee during surgery to help them with post-operative pain. This is to facilitate early mobilization and shorten the length of hospitalization.
Both knees are painfully affected by osteoarthritis, a degenerative condition that frequently affects all compartments in both knees. A bilateral total knee replacement is done to facilitate a meaningful rehab program and return the patient to gainful employment.
The surgical scar takes two weeks to heal. During this time, dressings are applied to prevent infection and facilitate good healing. The knee will also be compressed in wool and crepe dressing to reduce knee swelling and prevent bleeding after surgery. This compression will be lightened the next day, and ice packs are used to further reduce the swelling. It can take up to a month or two for the swelling to subside in some patients.
