We opted for sleeve reconstruction which is ideal for such a massive bone loss
The usual life of artificial knee joint is close to 20 years. But in some instances, the implant may separate from the bone, may be due to mismatch in the elasticity of bone and metal. This condition is called “Aseptic loosening” meaning loosening without infection (sepsis)
In such a situation one needs to do re surgery and change the implant. And usually the bone is soft and deficient so one needs revision implant
An implant may become loose either because of infection. In which case it is called Septic loosening.
