Current Research

Clinical Research

Current clinical research involves various clinical investigations in the area of hip and knee replacement. The current clinical areas that are under investigation are listed below:

  • The role of a flexion contracture in primary total knee arthroplasty.
  • The clinical difference between Luque wires versus cables as supplemental fixation in joint replacement surgery.
  • Is antibiotic resistance a clinical problem with the use of antibiotic impregnated cement?
  • Failure mechanisms and revision solutions associated with unicompartmental knee arthroplasties.
  • Isolated tibial component revision with retention of femoral component in revision knee arthroplasty.
  • Failure of TKR is related to Calculated Tibial Stresses: Explaining Why Well Aligned TKA's Fail & Malaligned TKA's Survive.
  • Large diameter femoral heads for the treatment of recurrent dislocation after total hip arthroplasty.
  • Long term outcomes of proximal femoral fractures in hip arthroplasty.
  • Early failure of the Scorpio Knee System.
  • Total knee arthroplasty for isolated patellofemoral arthritis in young patients.
  • Is There a Functional Benefit to Obtaining High Flexion After Total Knee Replacement?
  • The Effect of Retropatellar Fat Pad Excision on Patellar Tendon Contracture and Outcomes after Total Knee Replacement.
  • Two-incision minimally invasive total hip arthroplasty: A prospective, randomized controlled trial versus anterolateral and posterior single-incision approaches (funded by an OREF Zimmer Career Development Grant).

Biomechanical Research with Rose-Hulman Institute of Technology

  • Mechanical characteristics of proximal tibial loading and stresses in total knee arthroplasty: effect of tibial component alignment, polyethylene thickness and resection depth.
  • Initial fixation stability of acetabular components in revision THA: Biomechanical comparison of trabecular metal and titanium implants.
  • A novel method for prevention of intraoperative periprosthetic fracture during cementless hip arthroplasty: Vibration analysis during femoral component insertion.
