Inclusion Criteria

  • Has previously undergone or currently has been determined to undergo a primary THA with the study component MPO PROFEMUR® Preserve Classic Stem combined with any type of polyethylene or ceramic acetabular shells, acetabular liners and femoral heads.
  • Has previously undergone or currently has been determined to undergo a primary THA for any of the following:
  • non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia;
  • inflammatory degenerative joint disease such as rheumatoid arthritis;
  • correction of functional deformity
  • Willing and able to complete required study visits and assessments through the 10 year postoperative follow-up visit.
  • Previously implanted subjects must be enrolled within 3 years (+ 6 months) of their primary THA implantation.

Exclusion Criteria

  • Skeletally immature (less than 21 years of age) at time of implantation
  • Has or had an overt infection at the time of implantation
  • Has or had a distant foci of infections (which may cause hematogenous spread to the implant site) at the time of implantation
  • Has or had a rapid disease progression as manifested by joint destruction or bone absorption apparent on roentgenogram at the time of implantation
  • Has or had inadequate neuromuscular status (e.g., prior paralysis, fusion, and/or inadequate abductor strength), poor bone stock, poor skin coverage around the joint which would make the procedure unjustifiable
  • Has or had neuropathic joints
  • Has or had hepatitis or HIV infection
  • Has or had a neurological or musculoskeletal disease that may adversely affect gait or weight-bearing
  • Has or had a revision procedure(s) where other treatments or devices have failed; and treatment of fractures that are unmanageable using other techniques
  • Currently enrolled in another clinical investigation which could affect the endpoints of this protocol
