Candidates are those who have previously had a TKR and are now experiencing a worn-out or damaged prosthetic.
Candidates who still have a functioning prosthetic do not require revision surgery.
Like other surgeries, total knee revision requires certain general surgery protocol such as preoperative blood testing, use of prophylactic antibiotic medications, and cessation of smoking or use of pain relievers and anti-inflammatory drugs one week prior. You will likely be asked to stop eating or drinking the night before the surgery.
Your home should be modified to be more comfortable and ensure a safe and rapid recovery. It is a good idea to move your bed to the first floor and to get rid of hazards such as loose rugs.
Immediately after total knee revision, you will receive low-dose blood thinners to prevent dangerous blood clots that can form in the legs. You will stay in the hospital for 3 to 5 days. You will begin your rehabilitative exercises, which will focus on range of motion, normal walking mechanics and thigh muscle strengthening.
After total knee replacement surgery, you can expect to return to near-normal daily activities of in approximately 3 to 6 weeks. Still, you should avoid running, jogging or high impact sports. The more active you are with the prosthetic knee, the faster it will wear out. Cycling, swimming and walking are encouraged forms of exercise. A regimen of physical therapy to help you adjust to your new joint is usually part of a long-term recovery plan.
As with any surgery, there are risks of complications related to infection or adverse reactions to anesthesia. Other known complications include loosening of the prosthetic, necessity of revision surgery later on, and fracture of the bone holding the prosthetic. There is a small possibility of an allergic reaction to the prosthetic material, nerve damage, or complications arising from a blood transfusion (if one is necessary).
As revision surgery is more intensive and requires a longer amount of time under general anesthesia, there is a higher complication rate. In the process of replacing the prosthetic, further bone loss may occur.
