Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and non-pregnant female patients between 18-75 years of age.
  • Patients requiring uncemented primary Total Hip Arthroplasty (THA), suitable for the use of the Accolade stem and Trident/Tritanium cup.
  • Patients with a diagnosis of osteoarthritis (OA).
  • Patients who understand the conditions of the study and are willing and able to comply with the post-operative scheduled clinical and radiographic evaluations and the prescribed rehabilitation.
  • Patients who signed the Ethics Committee approved Informed Consent Form prior to surgery.

You may not qualify if:

  • Patients who require revision of a previously implanted hip prosthesis.
  • Patients who had a THA on contralateral side within the last 6 months.
  • Patients who had a THA on contralateral side more than 6 months ago and the rehabilitation period outcome was considered unsatisfactory or not good (Harris Hip Score \< 85).
  • Patients who will need lower limb joint replacement for another joint within one year.
  • Patients requiring bilateral hip replacement.
  • Patients who have had a prior procedure of acetabular osteotomy.
  • Patients with acute femoral fractures
  • Obese patients where obesity is severe enough to affect subject's ability to perform activities of daily living (body mass index, kg/m2: BMI ≥ 35).
  • Patients with active or suspected infection.
  • Patients with malignancy - active malignancy.
  • Patients with severe osteoporosis, rheumatoid arthritis (RA), Paget's disease or renal osteodystrophy.
  • Patients immunologically suppressed, or receiving steroids in excess of physiologic dose requirements.
  • The patient has a neuromuscular or neurosensory deficit which would limit the ability to assess the performance of the device or the patient has a neurological deficit which interferes with the patient's ability to limit weight bearing or places an extreme load on the implant during the healing period.
  • Female patients planning a pregnancy during the course of the study.
  • Patients with systemic or metabolic disorders leading to progressive bone deterioration.
  • +5 more criteria
