Subject is 18 - 80 years old (inclusive).
Subject has any of the following conditions:

Revision Subjects:
Exclusion Criteria:
All subjects:
Subject has conditions that would eliminate or tend to eliminate adequate implant support or prevent the use of an appropriately-sized implant, e.g.:
Subject has dysplasia of hip joint with CROWE Grade III, IV.
Subject has bodily disease(s) that may interfere with THA survival or outcome.
Subject has life expectancy of less than 10 years.
Subject has mental or neurological conditions which impair the subject's ability or willingness to restrict activities that may put the affected limb at risk.
Subject has physical conditions or activities which tend to place extreme loads on implants, e.g., Charcot joints, muscle deficiencies, multiple joint disabilities.
Subject has neuromuscular dysfunctions (paralysis, myolysis and abductor muscle weakness) which will cause unstable hip joint or abnormal gait after surgery.
Subject has an emotional or neurological condition that would pre-empt their ability or willingness to participate in the study.
Subject has an active infection - systemic or at the site of intended surgery.
Subject has a Body Mass Index > 40.0 kg/m².
Subject has a known allergy to any component of the devices used in the study.
Subject is pregnant or breast feeding.
Subject is entered in another investigational drug, biologic, or device study within 30 days of active study participation.

| Harris Hip Score (HHS) | The Harris Hip Score is a joint specific score that consists of 10 items covering domains of pain (1 item, 0-44 points), function (7 items, 0-47 points), functional activities, absence of deformity (1 item, 0 or 4 points), and hip range of motion (2 items, 0-5 points). Total scores range from 0 (worst) to 100 (best). The total scores and scores for each of the domains will be presented. The modified Harris Hip Score (mHHS) includes all the same domains as the HHS except for the hip range of motion (2 items, 0-5 points). Total mHHHs scores range from 0 (worst) to 95 (best). The total mHHS score maybe used in place of the total HHS score. | Pre-Op, 6 weeks, 6 months, 1 year, 2 years, 5 years, and 10 years |
| Five-level EuroQol five-dimensional (EQ-5D-5L) score | The EQ-5D-5L score consists of two parts: a descriptive system and a visual analogue scale. The descriptive system is used to describe the subject's health state and consists of five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels to choose the most appropriate answer: no problems, slight problems, moderate problems, severe problems and extreme problems. The subject is asked to indicate his/her health state by marking the most appropriate statement in each of the five areas. The visual analogue scale records the subject's self-rated health on a vertical visual analogue scale.The endpoints on the scale are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome as judged by the individual respondents. | Pre-Op, 6 weeks, 6 months, 1 year, 2 years, 3 years, 5 years, 7 years, and 10 years |
| Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS JR.) | The HOOS JR. is a short-form survey based on the Hip Disability and Osteoarthritis Outcome Score (HOOS) that specifically focuses on the outcome after THA. HOOS JR. consists of 2 areas: pain (2 items) and function, daily living (4 items). The last week is taken into consideration when answering the questions. Standardized answer options are given (5 Likert boxes - no, mild, moderate, severe, extreme) and each question gets a score from 0 to 4. An interval score from 0-100 (0 indicating total hip disability and 100 indicating perfect hip health) is calculated (15). | Pre-Op, 6 weeks, 6 months, 1 year, 2 years, 3 years, 5 years, 7 years, and 10 years |
| Forgotten Joint Score 12 (FJS-12) | The Forgotten Joint Score 12 (FJS-12) is a self-administered score where subjects are asked to rate their awareness of their hip arthroplasty in 12 questions with a five-point Likert response format: "Never", "almost never", "seldom", "sometimes" and "mostly". The item scores are summed and linearly transformed in a 0 to 100 scale with a high value reflecting the ability of the subject to forget about the replaced hip joint during the activities of daily living (i.e., higher score is a better outcome). | Pre-Op, 6 weeks, 6 months, 1 year, 2 years, 5 years, and 10 years |
