Patients who are suffering from inflammatory arthritis (e.g. rheumatoid arthritis)~10. Patients who have undamaged and functional collateral and posterior cruciate ligaments~11. Patients with a flexion greater than or equal to 90° on the affected side~12. Patients with a fixed flexion contracture less than 10°~13. Patients who understand the conditions of the study and are willing and able to comply with the prescribed rehabilitation and to perform all scheduled follow-up visits~14. Patients who have signed the Ethics Committee approved study-specific Informed Consent Form prior to the surgery~Exclusion Criteria:~1. Obese patients with BMI above 35 kg/m2 (severe obesity)~2. Previous partial knee replacement (unilateral, bicompartimental or patellofemoral joint replacement), patellectomy, high tibial osteotomy or femoral osteotomy in the affected knee~3. Primary Total Knee Replacement (TKR) in the affected knee~4. Varus or Valgus deformity greater than 20°~5. Patients with a fixed flexion contracture greater than 10°~6. Previous knee replacement on the contralateral side within the last year and whose outcome is achieving an KSS\< 70 points~7. Patients with symptomatic OA of the hips, spine, ankles, if it can interfere with the evaluation of the target knee~8.

Recurrent medical history of severe allergic or immune-mediated reactions~12. Vascular insufficiency of lower limbs severe enough to interfere with the study evaluation~13. Current treatment or treatment within the previous 2 years before the screening visit for malignant and life-threatening non-malignant disorders~14. Any clinically significant pathology based on clinical history that the Investigator feels may affect the study evaluation~15. Any intercurrent chronic disease or condition that may interfere with the completion of the 5-year follow-up, such as liver disease, severe coronary disease, alcohol or drug abuse, disordered mental state, or other clinically significant condition~16. Patients who have significant neurological or musculoskeletal disorders or disease that may adversely affect gait and compromise functional recovery and evaluation~17. Patients who have neuromuscular or neurosensory deficit which would limit the ability to assess the performance of the device~18. Patients with systemic or metabolic disorders leading to progressive bone deterioration~19. Patients who have a medical condition with less 5 years of life expectancy~20. Previous organ transplant surgery~21. Any psychiatric illness that would prevent comprehension of the details and nature of the study~22. Participation in any experimental drug/device study within the 6 months prior to the screening visit~23. Female patients who are pregnant, nursing, or planning a pregnancy
