Research Interests

My research interests relate to limb lengthening, deformity correction, and the Ilizarov method. While my main focus has been on clinical research, I have participated in basic science research to answer relevant clinical questions. My clinical research began with retrospective level 4 studies reviewing my experience. This has evolved with the growth of our service and clinical experience. Research quality has substantially improved to retrospective comparison and prospective comparison studies. I plan to continue to ask clinical questions and implement new treatment modalities within a responsible and organized clinical research program. As the service chief, I plan to mentor, support, and help my colleagues, fellows, residents, and students to follow in this path. As upcoming president of the Limb Lengthening and Reconstruction Society (LLRS), I plan to lead our national organization in the same direction. I plan to deliver an invited lecture at the upcoming LLRS specialty day of the AAOS entitled, “What are the 5 most important research questions that we should try to answer?” Through this, I hope to inspire and motivate others in the same direction. This may also be a springboard for organizing multi-center research projects.

Ongoing Research Projects:

  • Prospective evaluation of limb lengthening and reconstruction outcomes (Data Registry)
  • Changes in gait following surgical correction of genu varum in children and young adults (Prospective study in conjunction with gait lab at HSS)
  • Biomechanical effects of gradual correction of limb malalignment using external fixation: gait analysis (Prospective study in conjunction with gait lab at HSS)
  • MRI changes in ankles undergoing distraction arthroplasty
  • Oral antibiotics for prevention of pin tract infection: a prospective randomized study
  • Tibio-calcaneal fusion vs. below knee amputation: analysis of gait and function (prospective study)
  • The effect of platelet-rich plasma (PRP) injection into bone regenerate during distraction osteogenesis (prospective randomized study)
  • Cell count retrieval with bone marrow aspirate concentration- a prospective comparison of two systems
  • Complex ankle fusion using the Ilizarov method
  • Humerus lengthening using monolateral external fixation- functional outcome
  • Use of antibiotic coated intramedullary rod for ankle fusion
  • Knee arthrodesis and limb lengthening after failed infected knee arthroplasty
  • Tibia lengthening and the role for gastrocnemius recession
  • Treatment of severe hip arthrosis and massive apparent leg length inequality with total hip replacement.
