Surgical trainee assessment using a VE knee arthroscopy training system (VE-KATS): experimental results.

Previous work has described the development of a Virtual Environment Knee Arthroscopy Training System (VE-KATS): a collaborative project between the Orthopaedic Department, Hull and East Yorkshire Hospitals NHS Trust, Hull, U.K., and the Department of Computer Science, University of Hull, U.K. This work describes the initial results obtained by Orthopaedic Surgical Trainees using VE-KATS. The results showed that differences between individual trainees could be measured using the scoring system incorporated within VE-KATS. There was a weak correlation with the seniority of the surgical trainees.

An efficient method for modelling soft tissue in virtual environment training systems.

Modelling soft tissues in virtual environment training systems is frequently required. The provision of both visually compelling and physically accurate models presents a number of problems for the developer. The Finite element technique presented in this paper, modal analysis, can be programmed to allow the user to easily trade-off accuracy of simulation for execution speed. It has been successfully used to produce simulations of the lateral meniscus on low powered portable computer systems.

A portable virtual environment knee arthroscopy training system with objective scoring.

We have developed a Virtual Environment Knee Arthroscopy Training System (VE-KATS). Formative analysis indicated several features which surgical trainees indicated were necessary for a system to be useful. We have addressed this need by incorporating both rigid and deformable objects, simultaneous use of camera and surgical instrument, improved optical modeling, portability and low cost. A major advance has been the incorporation of automated objective scoring of performance. VE-KATS has now progressed to a viable training system which will be of practical benefit to trainee orthopaedic surgeons.
