About Your Surgery

About your surgery

For many it can be helpful to know what is happening inside your joint that is causing your pain. It's one thing to know that your cartilage is worn but it's another to understand the mechanics and be able to visualize the healing process. The information below is designed to help you understand what's going on in your joint so that it can you help you visually what your new joint will be like. 



The pain you are experiencing is can be caused by many things. Total joint surgeries can be done for many reasons such as:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Gout
  • Unusual bone growth or deformity
  • Knee injury

Osteoarthritis is the most common reason for total joint replacements and experienced by millions of people. Osteoarthritis occur when the cartilage wears away in a joint. The two joint surfaces rubs against each other, becoming very irritated. 


Total Knee Replacement

The purpose of joint replacement surgery is to replaces these worm surfaces with prosthesis composite comprised of smooth surfaces much like the healthy joint you once had. 

The thighbone (or femur) connects to your lower leg bone (tibia) at the knee. During a total knee replacement, the end of the femur bone is removed and replaced with an artificial piece. Likewise, the top end of the lower leg bone (tibia) is also removed and replaced with a matching low end. Potentially, a piece of the knee cap may also be replaced to complete the new joint.

Below you can see the different parts of your knee and how they fit together and why that smooth cartilage layer is so important.

    Total Hip Replacement

    In a total hip replacement, replaces the cartilage  and possibility damaged bone that is causing pain.
    The surgery consists of replacing the damaged top end of the femur with a prothesis. The prothesis is either cemented in or "press fit" into the bone.

    Now the top to your femur is a metal or ceramic ball which fits perfectly with the socket (acetabulum) which has been placed in your hip.
