  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients that have already made the decision to undergo total hip replacement and will receive the M2a- Taper™ Hip System.

Who may be able to join

  • Patients having primary cemented or cementless total hip replacement for non-inflammatory degenerative joint disease (NIDJD), or any of its composite diagnoses of:
  • Osteoarthritis,
  • Avascular Necrosis,
  • Traumatic arthritis,
  • Subcapital fracture,
  • Legg Perthes,
Show all 15Show fewer
  • Slipped Capital Epiphysis,
  • Fracture of the pelvis,
  • Diastrophic Variant
  • Patients with full skeletal maturity.
  • Patients undergoing unilateral total hip arthroplasty or bilateral total hip arthroplasty, either staged or simultaneously.
  • Patients of all races and gender.
  • Patients who are able to follow postoperative care instructions.
  • Patients who are able and willing to return for follow-up evaluations.
  • Patients have a preoperative total Harris Hip Score less than 70 with at least moderate pain.

Who cannot join

  • Patients diagnosed with inflammatory degenerative arthritis (IDJD) to include the following composite diagnoses: rheumatoid arthritis, systemic lupus erythematous, pigmented villonodular synovitis, juvenile rheumatoid arthritis and other arthritic processes of inflammatory or autoimmune etiology.
  • Patients less than 18 years.
  • Patients with the presence of a previous prosthetic hip replacement device (any type, including surface replacement arthroplasty, endoprosthesis, etc.) in the hip joint to be operated.
  • Patients with previous Girdlestone procedures.
  • Patients with above the knee amputation of the contralateral and/or ipsilateral leg.
  • Patients with osteoporosis, or marked bone loss which would preclude proper fixation of the prosthesis.
Show all 17Show fewer
  • Patients who are pregnant.
  • Patients with an active or suspected infection in or around the hip.
  • Patients with Parkinson's disease.
  • Patients with vascular insufficiency, muscular atrophy, or neuromuscular disease in the affected limb.
  • Patients with severe instability or deformity of the ligaments and/or surrounding soft tissue which would prelude stability of the prosthesis.
  • Patients with a highly communicable disease or diseases that may limit follow-up (e.g. immuno-compromised conditions, hepatitis, active tuberculosis, neoplastic disease, etc.).
  • Patients unwilling or unable to comply with a rehabilitation program for a cemented or cementless total hip replacement or who indicate difficulty or inability to return for follow-up visits prescribed by the study protocol.
  • Patients with previous hip surgery or conditions that may interfere with the total hip replacement's survival or outcome, e.g., Paget's disease, Charcot's disease, severe osteoporosis compromising bone stock (Dorr type C bone).
  • Patients who qualify for inclusion in the study, but refuse consent to participate in the study.
  • Patients with a "fused" hip.
  • Patients who have had a total hip arthroplasty on the contralateral hip within the last year.

Questions about this trial

What is this clinical trial studying?

An observational study of Non-inflammatory Degenerative Joint Disease and Osteoarthritis, run by Biomet Orthopedics, LLC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 21 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: due to low follow up). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Harris Hip Score (time frame: Postop, 12 weeks, 1 year, 3 years, 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jun 2017.
