REVISION TOTAL KNEE REPLACEMENT

One of the most successful medical operations is total knee replacement, or TKR. For the great majority of individuals, it allows them to live fuller, more active lives free from persistent knee pain. But a knee replacement can malfunction over time for a number of reasons. Your knee may become painful and swollen when this happens. It might also seem unstable or rigid, which would make it challenging to go about your daily business.

Your doctor might suggest revision total knee replacement as a second procedure if your first knee replacement doesn't work. During this process, your physician removes some or all of the original prosthesis' components and installs new ones in their place.

Revision surgery is not the same as primary total knee replacement, despite the fact that both treatments aim to reduce pain and enhance function. It is a more involved, drawn-out process that calls for careful planning, specialised implants, and instruments in order to get an excellent outcome.

Description

An implant, also known as a prosthesis consisting of metal and plastic components, replaces the knee joint during primary total knee replacement (TKR). While the majority of total knee replacements are incredibly successful, issues like implant wear and loosening may eventually necessitate a revision surgery to replace the original parts.

Revision surgery comes in various forms. There may be instances where only one implant or prosthesis component requires revision. In some cases, the entire knee joint—the femur, tibial, and patellar—has to be replaced or removed, and the surrounding bone needs to be reconstructed using either a bone transplant or augments, which are metal pieces that fill in the gaps in the bone.

When doing a revision knee replacement, the surgeon could find it challenging to use normal total knee implants due to bone damage. Usually, he or she will employ specialised implants with thicker, longer stems that fit deeper into the bone to provide additional support.
