Study Population
Individuals suitable for hip replacement using the Medacta SMS femoral stem

Inclusion Criteria:

  • Individuals with a severely painful and/or disabling hip joint with osteoarthritis, traumatic arthritis or developmental dysplasia of the hip or avascular necrosis of the femoral head.
  • In order to take part in this study, all study participants must be between the ages of 18 and 75 years of age, at the time of surgery.
  • Scheduled for a primary total hip replacement.

Exclusion Criteria:

  • Active infection
  • Pregnancy
  • Mental illness where the known condition is likely to compromise the patient's ability to consent, affect the patient's assessment of their progress or complete the 10 year cycle of follow-up appointments and reviews
  • Grossly distorted anatomy (surgeon's discretion)
  • Osteomalacia where uncemented implant fixation is contraindicated
  • Active rheumatoid arthritis.
  • Osteoporosis
  • Metabolic disorders which may impair bone formation where uncemented implant fixation is contraindicated
  • Muscular atrophy or neuromuscular disease
  • Allergy to implant material
  • Any patient who cannot or will not provide informed consent for participation in the study
