Frequently Asked Questions
Why does the ACL have to be sacrificed during total knee replacement surgery?
Because the ACL runs up the front and in between the condyles of your shin and thigh bone, it has to be removed in order to prepare the top of the tibia (shin bone) for the tibia baseplate (the replacement for the top of the tibia). The baseplate must cover the surface of the tibia to support the weight of the patient.
What makes this product unique?
The 3DKneeTM System is the first implant designed specifically to address the loss of the ACL. After the ACL is removed, the contact axis shifts from the inner quadrant of the knee to the outer quadrant. The polyethylene part of the implant – the cartilage replacement – is designed to accommodate the shift in the contact axis and restore stability, without undue stress on the components.The 3DKnee is designed specifically to work with the kinematics of a total knee patient.
What are the benefits to the patient?
The 3DKnee System is designed to achieve stability, improve range of motion and provide a longer lasting implant than conventional knee replacements.
What is involved in the surgical procedure?
The surgical procedure is conducted under general or regional anesthesia and generally takes 1 to 1½ hours to complete.
What is involved in the recovery process?
Patients will work with a physical therapist to resume daily activities and strengthen the muscles that support the knee. Your doctor will give you specific exercises designed to help you get back on your feet. Compliance with recommended rehab therapy will ensure optimal results.
How long before the patient can resume activities?
Most patients are able to walk within one day and resume daily activities within a few months.
