After knee replacement, symptoms such as loosening of the knee joint, infection, pain, and limited flexion and extension function suggest that the patella is not on track and needs to be re-revised. This means that the knee joint is removed and a new knee joint is reinstalled. It is important to determine the cause of the revision, whether it is an infection or due to a loose prosthesis, in order to determine the correct revision. The problems associated with revision surgery are bone defects, ligament defects, etc. The surgery time is prolonged and the risks and complications are higher, so the technique is more demanding.
