Eligibility
Key inclusion criteria
1. The patient is a suitable candidate for a Bicompartmental Knee Replacement and has
moderate to severe patellofemoral wear and medial compartment wear (surgeons
discretion)

2. The patient has no fixed flexion greater than 10 degrees.

3. The patient has maximal flexion greater than 100 degrees

4. The patient has a passively correctable varus deformity

5. The patient has a functionally Intact Anterior Cruciate Ligament (ACL.)

6. The patient has no significant patellofemoral malalignment

7. The patient has negligible lateral compartment degeneration with no appreciable loss
of cartilage height (surgeon's discretion).

8. The patient has pain that is not localised to the medial compartment only

9. The patient is a male or non-pregnant female.

10. The patient has signed the study specific, Human Research Ethics Committee (HREC)-
approved Informed Consent document and is willing and able to comply with the
specified pre-operative and post-operative clinical and radiographic evaluations
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. The patient has a clinically deficient ACL and cruciate and collateral ligament
insufficiency on CT arthrogram.

2. The patient is undergoing revision surgery

3. The patient has greater than 10° of hyperextension, greater than 10° of varus or
valgus deformity, greater than 10° Flexion Contracture

4. The patient has active, local infection or previous intra-articular infection

5. The patient has skeletal immaturity

6. The patient is without sufficient bone stock to allow appropriate insertion and
fixation of the prosthesis

7. The patient's weight, age or activity level might cause extreme loads and early
failure of the system (surgeons discretion).

8. The patient has a systemic or local condition that would limit the ability to assess
the performance of the device e.g. neuromuscular or neurosensory deficiency, disorder
leading to progressive bone deterioration (including rheumatoid arthritis and
osteoporosis), or patient is immunologically suppressed.

9. Patient has a cognitive impairment, an intellectual disability or a mental illness
that is considered by the investigator to inhibit the patient's capacity to consent to
research and the ability to participate in it

10. Patients with tricompartmental disease are contraindicated from the study
