Despite the current sterile techniques used for all surgeries, infections are always a possibility following this procedure. Infections however occur rarely, in 1-2 out of 100 procedures. The treatment options will vary depending on the location of the infection. Infections can range from very minor ones that are only treated with antibiotics with or without a few extra days in the hospital to very major infections requiring a repeat surgery. If an infection develops within the knee a repeat surgery may be performed and the implant removed. Furthermore, if the infection cannot be cured, the knee may have to be fused which results in a lack of knee movement. In extreme cases, an amputation could result if the infection is life-threatening.
