An artificial knee is replaced through a surgical procedure that involves preparing the knee joint and attaching prosthetic components to the bones.
Procedure for Artificial Knee Replacement
Here's a breakdown of the steps involved in replacing an artificial knee, based on the information provided:
- Kneecap Preparation: The underside of the kneecap is cut to prepare it for the new prosthetic pieces. This ensures a proper fit and function.
- Prosthesis Attachment: Two main parts of the prosthesis are attached to the bones of the knee joint:
- One part is fastened to the end of the thigh bone (femur).
- The other part is attached to the top of the shin bone (tibia).
- Attachment Methods: These prosthetic parts can be secured using two primary methods:
- Bone cement: A special adhesive is used to hold the prosthesis in place.
- Screws: The components can also be fastened to the bone with screws for stability.
These steps are crucial for the successful replacement of an artificial knee, allowing for improved mobility and reduced pain.
