Description of intervention(s) / exposure
Treatment: Devices - Prophecy Technique
Treatment: Devices - Navigation System

Active Comparator: Navigation alone - Navigation system alone vs Prophecy technique with Navigation system validation

Experimental: Prophecy and Navigation validation -


Treatment: Devices: Prophecy Technique
Navigation computerised system is used intraoperatively to correct implant the Advance knee implant. Prophecy is a pre-alignment technique where a pre-op MRI or CT scan is used to manufacture personalised cutting blocks to assist the surgeon in correct implanting the Advance knee implant intraoperatively

4. Patients who understand the conditions of the study and are willing to participate for
the length of the prescribed term of follow-up.

5. Patients who are capable of, and have given, informed consent to their participation
in the study.

6. The individual does not have an active infection within the affected joint.

7. The individual has not had a previous total knee replacement or knee fusion of the
affected knee joint.

8. The individual is skeletally mature.

Can healthy volunteers participate?
No
Key exclusion criteria
1. Previous surgery requiring implanting a device.

2. Knee deformity is >30° anatomic varus (as measured on an AP radiograph taken with the
patient standing)

3. Knee deformity is >30° anatomic valgus (as measured on an AP radiograph taken with the
patient standing) >20° knee flexion contracture (as measured by investigator
examination)

4. Those patients requiring bone grafting or any other procedure that would extend the
operative time beyond that of just replacing the knee should be excluded.

5. The individual is classified as morbidly obese (>40 BMI).

6. The individual is physically or mentally compromised (i.e., currently being treated
for a psychiatric disorder, senile dementia, Alzheimer's disease, presence of alcohol
or substance abuse), and is unwilling or unable to comply with postoperative scheduled
clinical and radiographic evaluation and rehabilitation.

7. The individual has a neuromuscular or neuro-sensory deficiency which limits the
ability to evaluate the safety and effectiveness of the device.

Summary
Brief summary
This project aims to assess two different techniques used to position the knee replacement
implant during surgery. The patients will be randomised to receive either the following:

1. The established Navigation System (gold standard)

2. The new Prophecy Technique (validated by the Navigation System)

The study hypothesis is there will be no difference between the gold standard Navigation
system and the Prophecy technique in relation to the placement of the knee implant.
