Total Knee Replacement (TKR)

Cementing the components

1. Use a small piece of resected bone to plug the femoral intramedullary canal to relieve any post-operative blood loss into the wound.

2. All resected surfaces must be thoroughly cleaned, preferably with pressurised lavage, and dried. It is advisable to use suction to remove the debris and liquid trapped in the cavities of the trabecular bone.

3. Ideally cement is applied to all the internal surfaces of the femoral component and to all of the resected femoral bone surfaces. Similarly, cement is applied to the underside of the tibial component , the tibial plateau and the tibial stem hole. The components can be implanted simultaneously or sequentially.

4. After impacting the implants, care should be taken to remove all extruded surplus cement, especially from the posterior condyles of the femoral component. The cement can be pressurised whilst setting by extending the leg to 0º C or slight hyper-extension.
