Knee revision surgery is a revision surgery which is performed when the primary knee replacement fails and your surgeon removes some or all the parts of the original prosthesis and replaces them with the new ones. It is a longer and more complex procedure. In this procedure, you are administered general or regional nerve block anesthesia. During the surgery, incisions will be made to remove the original implant while preserving as much as bone as possible. The bone surfaces will be prepared for the revision implant. In rare cases, bone graft material is also used to help rebuild the knee. Then, the doctor inserts the specialized revision implant. A drain may be placed in your knee to collect any fluid or blood that may remain after the surgery.
You will be admitted to the hospital and you shall undergo medical investigations required prior to surgery. Investigation reports are evaluated and you are explained about the procedure. Pre anaesthetic check-up (PAC) is conducted and your consent for the procedure is taken.
You would be moved to OT. You would undergo spinal anaesthesia and surgery will then be performed. After the surgery, you will be shifted to normal hospital room. Pain medications would be started. You may have a X-Ray of operated joint.
You would wear a knee immobilizer and undergo cold therapy unit on the knee. Our rehabilitation team would help you in getting mobilized.
You will get out of bed with walker or cane and perform post-operative exercises. You will be discharged with follow up instructions on medications and physiotherapy.
It takes about 4-8 weeks for complete recovery after surgery. You would be asked to visit the doctor after 8-10 following surgery for incision inspection and stiches/stapler removal.
During 1-3 weeks after surgery you would need walking aids, either walker or cane can be used. You may need an elevated commode seat and grab bar in washroom for safety.
