Knee Joint

Knee Joint

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 group...

This study introduces a novel arthroscopic surgical training simulator. Force guidance significantly improves trainee performance, reducing errors and operation time for better surgical skill development.

Area of Science:

Medical Simulation
Surgical Training
Virtual Reality

Background:

Arthroscopic surgery presents significant training challenges due to limited visibility and complex hand-eye coordination.
Traditional methods and existing virtual reality (VR) systems lack direct expert guidance.

Purpose of the Study:

To develop and evaluate an experience-based arthroscopic training simulator.
To integrate motion tracking and haptic feedback for realistic surgical procedure reproduction.

Main Methods:

Captured arthroscopic trajectories from experienced surgeons.
Utilized a haptic device to guide trainees in a virtual environment.
Compared trainee performance with and without force guidance.

Augmented Reality Navigation-Guided Core Decompression for Osteonecrosis of Femoral Head

Published on: April 12, 2022

Main Results:

Performance improved after repeated practice on the simulator.
Force guidance led to better performance than without it.
Force guidance reduced average error by 33.01% and operation time by 14.95%.

Conclusions:

Developed a novel virtual knee arthroscopic training system with haptic guidance.
The system tracks and reproduces real-life procedures, creating a valuable training database.
Force guidance effectively shortens the learning curve for novice surgeons, enhancing skill acquisition.
