The bone cement commonly used in Total Knee Replacement (TKR) is polymethylmethacrylate (PMMA) bone cement.
Polymethylmethacrylate (PMMA) Bone Cement in TKR
PMMA bone cement plays a crucial role in securing the implant to the bone, facilitating stability and long-term success. While fully uncemented fixation is uncommon in Revision Total Knee Arthroplasty (RTKA), PMMA cement provides a reliable method for fixation. Here's a breakdown:
- Primary Function: Anchoring the prosthesis to the bone.
- Material Composition: Polymethylmethacrylate (PMMA).
- Usage Context: Particularly important in RTKA where fully uncemented fixation is rarely employed.
