Metal Ion Level Primary · Baseline to Study Completion, up to 20 years

All participants at Baseline and every three years afterwards up to 20 years will have whole blood collected for metal ion testing of whole blood cobalt (Co) and chromium (Cr). Symptomatic participants with pain, swelling, and/or functional limitations if assessed by the Principal Investigator to be related to the implant will have whole blood collected for metal ion testing of cobalt and chromium annually.

Number of Participants With Cobalt (Co) and Chromium (Cr) Metal Ions > 7 Parts-Per-Billion (Ppb) Primary · Baseline to study completion, up to 20 years

Number of participants with whole blood cobalt (Co) and/or chromium (Cr) \> 7 ppb (Yes/No). Participants as 'Yes' to Co and/or Cr will have Metal Artifact Reduction Sequence (MARS) Magnetic Resonance Imaging (MRI) performed (or Computerized tomography (CT) if MRI is contraindicated). This is used to detect pseudotumors, abductor muscle atrophy, and tendinous pathology in patients with painful metal-on-metal (MOM) hip arthroplasty.

The Hip Osteoarthritis Outcomes Score Junior (HOOS JR) Questionnaire Secondary · Baseline to study completion, up to 20 years

The HOOS JR. questionnaire consists of 6 questions. These focus on 3 categories: joint pain, stiffness and function in daily living. The HOOS JR. questionnaire, allows patients to rate each activity by indicating the amount of pain or disability they experience while carrying them out. Raw scores are added up and then converted to an interval score (0-100) using an interval table. The final interval score represents a patients total joint disability where 0 corresponds to total joint disability (i.e., worse outcome) and 100 is perfect joint health (i.e., best outcome).

Sponsor's own description

This is a prospective, single arm, sequential enrolment study to collect relevant clinical and radiological data in approximately 26 subjects, at one site in Australia, who have been implanted with the SMF Short Modular Femoral Stem Hip System in a primary THA procedure to assess its safety and efficacy up to 20 years post-surgery.
