Orthopedic Biomechanics Laboratory

Research Theme

Research in the Orthopedic Biomechanics Lab deals primarily with the prevention, treatment, repair, and rehabilitation of damaged or degraded tissue in the human knee.

Ongoing Research Questions

Total Knee Arthroplasty (TKA)

  • Does kinematically-aligned TKA restore the envelopes of  passive motion closer to normal and better balance and center the contact forces than mechanically-aligned TKA?
  • Does kinematically-aligned TKA restore the rotational axes of the intact tibiofemoral joint?
  • What are the changes in joint line and limb alignment due to surgical alignment method and radiographic alignment of the leg?
  • What are the envelopes of passive motion of the normal tibiofemoral joint?
  • What is the effect of coronal and rotational alignment of TKA components on the contact forces and passive motion envelopes of the tibiofemoral joint?
  • What is the optimal design of an instrumented spatial linkage that minimizes error when locating the rotational axes of the tibiofemoral joint?
  • How accurate are 3D models from MRI and CT in planning components position in kinematically-aligned TKA?
  • What is the effect of cutting guide error in Total Knee Arthroplasty on the contact forces and passive envelopes of motion of the tibiofemoral joint?

ACL Reconstruction

  • What is the change in anterior laxity of the tibiofemoral joint five years after ACL reconstruction?
