Knee replacements is the most successful of all joint replacements and I personally have performed over 1000 of these. The current technology allows us to do these through small incisions and recovery is relatively quick.
Complication rates are low and are about 1-2% in incidence. Patients can expect the implants to last for easily between 15 and 20 years if not longer. There are many prosthesis available on the market the ones we use are the ones that are most widely used in the world and that have stood the test of time.
