What happens during a knee replacement?

Jeannie Winselman and Audrey Clough

Our joints are something that wear away and eventually may need to be replaced. Often this can be a scary proposition, acknowledging that our body does not work the way it used to. There’s also the worry that something could go wrong and you could be worse off than before.

However, knee replacements are quite common now. Let’s take a look at what you might be preparing for.

Depending on the severity of your problem, you can get either get a partial or total knee replacement. Total knee replacements are the most common. In a total knee replacement, the doctor takes out the damaged bone and replaces it with an implant, taking time to shape it so it fits snugly. There are four main parts to this type of surgery:
• Slicing off the damaged cartilage from the ends of the femur and tibia, plus a small amount of bone underneath to prepare the area for the new joint.
• Putting the new implant on.
• Placing a plastic button under the patella to mimic the action of it.
• Recreating a smooth surface like your old knee with a medical grade plastic spacer between the tibia and femur.

This type of surgery works well for about 90 percent of patients, with a near-perfect rate of 90-95 percent after 10 years. The biggest risk is infection. A lesser risk is the implant not being properly aligned, which could result in a trip back to the operating room. Rehab is very important to ensure the knee works well. You need to get that knee moving right away to make sure that joint doesn’t “freeze.”
Many of our patrons have either had knee replacements or are contemplating having this procedure performed. Hopefully you will find this information helpful, knowing what happens during a knee replacement.
