Revision Knee Replacement Surgery

Total Knee Replacement is one of the most successful Orthopaedic procedures of this century. This form of surgery provides relief to the patient from pain, restores knee function and improves quality of life. With improved implant designs and surgical techniques, a primary KneeReplacement can be expected to function for at least 15 to 20 years. However, in some cases, these procedures may fail and require a second surgery called Revision Knee Replacement.

Revision Knee Replacement is a procedure where previously failed primary implants are removed and a new prosthetic implant is fixed. This is a complex procedure and requires planning, special operative tools and revision implants.

Very often, there are bone deficiencies that are to be addressed during Revision Knee Surgery for which bone grafts of various types and wedges made up of trabecular metal are used. There are various reasons for a failed implant. Some of these are wear of prosthetic part over time, loosening of prosthesis, infection, fracture around the prosthesis, instability and various patient related factors.

Fractures around the prosthesis may occur after an accidental fall or other injury around the knee which may loosen the implant requiring revision surgery. Most Revision Total Knee Replacement Surgery takes longer to perform than primary procedures (2-3 hours). The first step is to remove old implants and fill up bony defects by bone grafts or bone substitutes.

Post-operative care after Revision Knee Replacement is similar to the care of a primary knee procedure. This includes combination of physical therapy, blood management and pain medications as necessary. Antibiotics and some method of blood clot prevention will continue in postoperative phase. A brace or a splint may be used to protect the joint after the surgery.
