Gender | All |
Age group | 18 Years and older |
Eligibility | Inclusion Criteria: - Patient is 18 years of age minimum. - Patient is suffering from severe hip pain and disability requiring primary unilateral or bilateral total hip arthroplasty based on physical exam and medical history. - Patient is willing and able to cooperate in the required post-operative therapy. - Patient is willing and able to complete scheduled follow-up evaluations as described in the Informed Consent. Exclusion Criteria: - Patient is unwilling or unable to give consent, or to comply with the follow-up program. - Acute, chronic, local, or systemic infections. - Severe muscular, neural, or vascular diseases that endanger the limbs involved. - Lack of bony structures proximal or distal to the joint, so that good anchorage of the implant is unlikely or impossible. - Total or partial absence of the muscular or ligamentous apparatus. - Any concomitant diseases that can jeopardize the functioning and the success of the implant. - Allergy to the implanted material, especially to metal (e.g., stainless steel). - Local bone tumors and/or cysts. - Pregnancy - Skeletal immaturity - Patients who have any condition that would in the judgment of the Investigator place the patient at undue risk or interfere with the study. Any patient who is institutionalized, a known drug abuser or alcoholic or anyone who cannot understand what is required of them. - Patients with plans to relocate during the study follow-up period. - For patients biologically younger than 60 years with joint disease, a different reconstruction operation (e.g., osteotomy) or arthrodesis may be indicated. |

Primary | Implant survival based on removal or intended removal of the device and determined using the Kaplan-Meier method | 10 years | ||
Secondary | The results of the hip surgery will be determined by the Harris Hip Score | The Harris Hip Score is a questionnaire filled by the surgeon with the patient who received a hip implant. The domains covered are pain, function, absence of deformity, and range of motion. The pain domain measures pain severity and its effect on activities and need for pain medication.
The function domain consists of daily activities (stair use, using public transportation, sitting, and managing shoes and socks) and gait (limp, support needed, and walking distance). Deformity takes into account hip flexion, adduction, internal rotation, and extremity length discrepancy. Range of motion measures hip flexion, abduction, external and internal rotation, and adduction. There are 10 items. The score has a maximum of 100 points (best possible outcome) covering pain (1 item, 0-44 points), function (7 items, 0-47 points), absence of deformity (1 item, 4 points), and range of motion (2 items, 5 points). |

Secondary | The patient's quality-of-life will be determined by the EQ-5D score | EQ-5D is a standardized instrument for measuring health status. It is made up for two components.
The description part: health status is measured in five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Mobility dimension asks about the person's walking ability. Self-care dimension asks about the ability to wash or dress by oneself. Usual activities dimension measures performance in "work, study, housework, family or leisure activities". In pain/discomfort dimension, it asks how much pain or discomfort they have. In anxiety/depression dimension, it asks how anxious or depressed they are. Visual analogue scale: The patient marks his health status on the day of the interview on a 20 cm vertical scale with end points of 0 and 100. The bottom rate (0) corresponds to " the worst health you can imagine", and the highest rate (100) corresponds to "the best health you can imagine". |
10 years | |
Secondary | Abnormalities determined on X-rays in the bone region surrounding the implant will be reported | 10 years | ||
Secondary | Number of patient with adverse events related to the implant will be reported | Adverse events include: dislocations of the hip, revisions and removals of the implants | 10 years |
