Eligibility | Inclusion Criteria: - Clinical condition included in the approved Indications For Use for the Conformis Hip System and the Cordera Hip System - Osteoarthritis, as confirmed by the investigator's assessment of disease status at screening visit that warrants a THR procedure - Willingness to participate in the clinical study, to give informed consent, and to attend all follow-up visits - > 18 years of age Exclusion Criteria: - Simultaneous bilateral procedure required - BMI > 40 - Poorly controlled diabetes (defined as HbA1c>7 or Investigator discretion) - Crowe classification of hip dysplasia, grades 2, 3, or 4 - Active malignancy (defined as a history of any invasive malignancy - except non-melanoma skin cancer), unless patient has been treated with curative intent and there have been no clinical signs or symptoms of the malignancy for at least 5 years - Other lower extremity surgery planned within 1 year of consent to the affected limb Contralateral THR surgery within 3 months pre or post index surgery - Neuromuscular conditions which prevent patient from participating in study activities - Active local or systemic infection which precludes THR procedure - Immunocompromised in the opinion of the Investigator - Medically diagnosed fibromyalgia or similar conditions that might impact the patient's ability to differentiate source of pain - Rheumatoid arthritis or other forms of inflammatory joint disease - Loss of bone or musculature, osteonecrosis, neuromuscular or vascular compromise in the area of the joint to be operated on, to an extent that the procedure is unjustified - Diagnosed with or receiving treatment for osteoporosis that is likely to confound results in the opinion of the Investigator - Physical disability affecting the lumbar spine that is likely to confound results in the opinion of the Investigator - Charcot or Paget's disease - Inability to complete the protocol in the opinion of the clinical staff due to safety or other reasons - Participation in another clinical study which would confound results - Allergy to any of the implant materials |
