People sometimes ask what the difference is between a knee reconstruction and a knee replacement. Sometimes these two things get confused. They are really quite different.
A knee reconstruction would often be needed as a result of a sporting or similar injury to someone’s knee. The goal of the surgery is to stabilise ligament damage by repairing or grafting (reconstructing) a torn ligament. Usually the actual joint surfaces in the knee of someone having a knee reconstruction would be ok. This is often an operation for a somewhat younger age group than a knee replacement. The surgery is often done for giving way problems.
A knee replacement is generally undertaken for a worn out knee where the cartilage surfaces themselves are worn down to the bone. This procedure involves replacing the actual surface of the worn knee with a new surface. The ligaments would normally be ok in someone having a knee replacement. Even if the ligaments aren’t ok, it is usually not too much of an issue with modern techniques. Knee replacements are usually primarily done for knee pain.
There are big differences in the alternatives, preparation before, and rehabilitation after the procedures. Knee replacements are also quite a bit more commonly needed than reconstructions. That can be important as in the private system, some levels of health fund cover will cover less commonly needed knee reconstructions but not knee replacements. A typical item number for a reconstruction is 49539 and for a replacement it’s 49518. Those numbers can clear up discussions about levels of cover with health funds.
They are both effective treatments for the different problems they address, although risks always need to be considered. There is some further information at drsammartin.com along with some detailed information booklets about joint replacement to download.
