Cruciate Retaining Knee Joint Replacement
A cruciate retaining knee joint replacement is a type of total knee replacement surgery that preserves the posterior cruciate ligament in the knee joint.
During this surgery, damaged or diseased parts of the knee joint, including the femur, tibia, and sometimes the patella, are removed and replaced with artificial prosthetic components.
Unlike some other knee replacement techniques, the posterior cruciate ligament is retained along with its attachments to the bones.
The main advantage is that it maintains more natural knee biomechanics, particularly stability and range of motion.
This surgery may be recommended for patients who have an intact and functioning posterior cruciate ligament and good ligamentous stability.
Key Points
- Preserves the posterior cruciate ligament where suitable.
- Designed to replicate more natural knee movement.
- May be useful for selected arthritis cases with good ligament stability.
- Requires proper assessment of ligament condition, bone quality, and individual patient factors.
