Knee Joint01:23

Knee Joint

3.7K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Area of Science:

  • Biomechanics
  • Computational modeling
  • Orthopedic research

Background:

  • Virtual knee joint models are crucial for understanding knee mechanics in health and disease.
  • Existing models are often not freely accessible or customizable, hindering clinical translation.
  • A gap exists for readily available, adaptable knee simulation tools.

Purpose of the Study:

  • To introduce Open Knee, an open-source finite element model of the tibiofemoral joint.
  • To provide a detailed anatomical and mechanical representation of knee structures.
  • To demonstrate the model's utility through various use cases.

Main Methods:

  • Development of an open-source finite element model (Open Knee) of the tibiofemoral joint.
  • Inclusion of detailed anatomical structures and their nonlinear mechanical properties.
  • Validation through use cases including passive flexion, meniscectomy effects, and anterior cruciate ligament mechanics.

Main Results:

  • Open Knee provides a detailed, customizable finite element representation of the tibiofemoral joint.
  • Use cases demonstrate its capacity to predict joint movements and analyze surgical impacts.
  • The model has been utilized by external investigators, highlighting the value of open-source sharing.

Conclusions:

  • Open-source models like Open Knee accelerate simulation-based medicine and scientific discovery.
  • The model facilitates research into knee mechanics, surgical outcomes, and implant performance.
  • Future work should focus on next-generation models incorporating individualized anatomy and properties.
