The patient underwent a knee replacement operation using the Persona implant. During the procedure, the patella is laterally subluxed, and the knee is exposed in flexion. The affected joint tissue is surgically removed and replaced by a knee prosthesis which consists of three separate components. The distal part of the femur is resurfaced with a femoral component made out of a CoCr Mb alloy that corresponds to the bone’s natural shape. After damaged cartilage is resected, the proximal part of the tibia is resurfaced with a metal plate made of the same material as the femoral component and followed by the implantation of a highly cross-linked polyethelyne insert which articulates with the femoral component.
This results in improved knee function and significantly relieves severe pain caused by degenerative joint diseases. All in all, a total knee replacement is one of the most successful examples of innovative surgery and has resulted in substantial quality-of-life gains for people with severe joint problems.
Even though knee replacement surgery is not an urgent operation, but if the patient is in pain, postponing surgery affects the patient’s quality of life and prolonged use of painkillers has negative side effects.
