Area of Science:

  • Biomedical Engineering
  • Orthopedic Surgery
  • Biomechanics

Background:

  • Accurate in vivo measurement of tibiofemoral forces is crucial for total knee arthroplasty (TKA) to understand polyethylene stresses, implant load distribution, and bone-implant interface stress.
  • Existing theoretical models for estimating tibiofemoral forces show significant variability due to the knee's complex biomechanics, including multiple degrees of freedom, joint geometry, ligamentous structures, musculature, and the patellofemoral joint.

Purpose of the Study:

  • To design, manufacture, and test a prototype instrumented tibial prosthesis capable of accurately measuring in vivo tibiofemoral forces.
  • To provide a tool for validating existing knee models and developing more accurate predictive models for tibiofemoral joint loading.

Main Methods:

  • Development of a prototype instrumented tibial prosthesis for total knee replacement.

    Conclusions:

    • The developed instrumented tibial prosthesis offers an accurate method for in vivo tibiofemoral force measurement in TKA.
    • This technology can validate and refine existing knee models, leading to improved implant design and wear simulation.
    • Potential applications include intraoperative soft-tissue balancing, and evaluating the impact of rehabilitation, bracing, and daily activities on knee joint forces.
