Total knee replacement procedure
- Bone preparation: The damaged surfaces of the cartilage at the ends of the tibia and femur are removed along with some underlying bone.
- Implant positioning: Removed cartilage surface and bone are replaced with metal components to create the joint surface.
- Patella resurfacing: The undersurface of the knee cap (patella) is attached with a plastic button. In some cases, this is not needed.
- Implanting a spacer: A medical grade plastic implant is inserted in between the mental components to create a gliding motion.
Post operative period:
- Hospitalization for three to four days
- Knee motion and strengthening exercises are taught
- Patients is made to walk using a walker
- Takes around four to six weeks to get back to normal walking without the help of walker
- Intraoperative complications could be damage to the collateral ligaments, neurovascular structures and fractures.
- Postoperative complications include infections and thromboembolism.
- Late stage complications could be an infection, instability, periprosthetic fracture and aseptic loosening.
