It means to remove the old implant and put a new one.
The most common causes are Aseptic Loosening, Infection, Instability, Fracture involving the implant.
When we improve the implant, part of the bone comes out, and ligaments get stretched. So the implant that we put will be of the next level, i.e., more constrained.
In case of infection, we will do it in 2 stages. In the first stage, we remove the affected implant, clean the surfaces, apply Antibiotic laden cement. Wait for 6-8 weeks and then reoperate, remove the cement spacers, clean and, put the new implant.
In non-infectious cases, We can do revise in a single-stage.
Revisions are usually of all the components, but in very early mild infections, we can debride and change only the poly insert.
The Patient has to be optimized as the duration of Surgery is much longer than the primary surgery.
The more constrained the Implant design, the life span of the implant decreases.
