Introduction: Total Knee Replacement is one of the most successful procedure over last 50 years,allowing patients to live more productive and active lives free of chronic pain.
With more joint replacements performed every year and procedures extending to treat younger more active patients, there is an increase in need of Revision Total Knee Replacement.
Over a period of time the Knee Replacement may fail due to a variety of reasons. When your Knee Replacement fails, then what you need is a second surgery i.e. Revision Total Knee Replacement where your doctor will remove some or entire part of original implant and replace them with new implant.
