Total Knee Replacement-
Total Knee replacements are performed when arthritis in the joint worsens. Arthritis is a condition caused by many factors, which result in the destruction or loss of cartilage from inside the knee joint. When the cartilage is lost, there is no recovery of the same type of cartilage in the knee. When enough cartilage is lost, the joint fails to absorb the shock and the knee becomes painful due to the release of inflammatory products in the knee as the bone is exposed.
The treatment of arthritis in the knee differs from patient to patient. In general, once the pain affects normal activities, and is a constant problem, then it should be treated with surgery. In the lead up to surgery, there are multiple things that can be done to diminish the pain from arthritis. There is nothing that we can currently do to reverse the degeneration of cartilage. Some newer modalities such as stem cell research may prove to be valuable, however this looks to be a future possibility only.
Often you general practitioner will manage knee arthritis until it is referred to an orthopaedic surgeon. In Adelaide, South Australia it is often the case, that a General Practitioner will give medication such as antiinflammatories to diminish the pain from arthritis. As pain from arthritis is due to inflammation, it is often best treated with products such as Nurofen. It is advisable to obtain medication advice from your doctor prior to taking any new medications.
Patient specific Instruments can help in achieving this alignment as all of the calculations are done prior to the operation. No alignment guides are necessary during the operation, and it has been shown in multiple studies to have reproducible results. Patient specific instruments are made by taking an image of the knee and reproducing it in a computer, similar to how blueprints and prototypes are made (i.e. using a program like AutoCAD). This is highly accurate, and can identify what is necessary to obtain the perfect alignment.
