The surgical procedure
A knee prosthesis is implanted through a conventional or minimally-invasive incision at the front of the knee.
The tissue is severed and the bones of the joint are displayed. The bone is removed and usually first the thigh portion of the knee prosthesis is implanted. Thereafter, the tibial bone must be prepared for receiving the knee implant.
The personalised prosthesis parts – partly cemented and partly cementless – are inserted.
Finally, the area is closed back up gradually, the skin is sutured and a sterile wound dressing placed.
In most cases after a knee prosthesis is inserted, it can bear weight immediately. However, this is not always the case and it depends on the bone quality.
Subsequent use of forearm crutches can help to reduce pain during the first few days following the operation. Supportive motor / moving rails can also be used in the first days after the operation (so-called CPM = continuous passive motion).
Dressings are changed and wounds drained approximately 2 days after surgery. The patient is discharged after approximately 5 to 7 days.
Depending on your job, you can resume work after about 6 to 8 weeks.
