This prospective, randomized study will study the 2 year survivorship and short term outcomes of a currently-used femoral stem: the Bone Preservation Tri-Lock femoral stem using two surgical approaches. The surgical approaches being studied are direct anterior and anterolateral. Implant survivorship, radiographic positioning, and functional outcomes will be compared. Subjects will be randomized to surgical approach and followed for a period of two years.

Condition Intervention
Total Hip Arthroplasty
Procedure: Total Hip Arthroplasty

Study Type: Interventional
Study Design: Primary Purpose: Treatment

Further study details as provided by Rothman Institute Orthopaedics:

Primary Outcome Measures:
  • Survivorship of Bone Preservation Tri-Lock femoral stem [ Time Frame: 2 years post-op ]
    Survivorship will be assessed via radiographic (x-ray) analysis and need for revision surgery (if patient had femoral stem removed for any reason within the first two years after surgery).

Secondary Outcome Measures:
  • TUG (timed up and go) Score [ Time Frame: 6 weeks post-op ]

Arms Assigned Interventions
Active Comparator: Total Hip Arthroplasty performed via direct anterior approach Procedure: Total Hip Arthroplasty
Active Comparator: Total Hip Arthroplasty using anterolateral approach Procedure: Total Hip Arthroplasty
