Knee replacement surgery involves the replacement of a severely degenerated joint by a prosthetic joint or prosthesis. Knee replacements have been performed for over fifty years and is considered to be one of the most successful operations in the surgeon’s repertoire.
The most common reason for a total knee replacement is because of degenerative changes brought about by osteoarthritis (= degenerative process). Some people need knee replacements for other reasons such as rheumatoid arthritis (auto-immune disease) congenital condition and sometimes because of trauma of the joint.
Ideal goals of knee replacement are first to alleviate your symptoms for the longest time possible (ideally one surgery for life) and second to give you the best joint performance and feeling (ideally like a normal joint).
Knee joint replacements can be either “partial” or “total” depending on if the joint is partially or totally replaced. Partial knee replacements are illustrated by uni-compartmental knee replacement (UKR) of the femorotibial joint, and by patellofemoral joint replacement (PFJ).
There are many implant designs and techniques for fixation of implants in the bone. Each one has its specific pros and cons and is more suitable to a certain sub-group of patients. That is the reason explaining why Charles will suggest to every patient a different combination of implant type and method of fixation, in order to reach optimal outcome for everyone.
