Background and objectives: As conventional knee replacement training requires bone model, computer-assisted simulation seems to be an attractive alternative. Therefore, we compared the transfer of conventional training for the knee replacement and computer-assisted simulation to surgery in this trial.
Design: A prospective randomized trial.
Methods: The study was performed in Sun Yat-sen Memorial Hospital, Sun Yat-sen University, Guangzhou, China. After completing an intensive course in basic theory of total knee arthroplasty (TKA), three groups of 10 participants proceeded with no additional training (control group), 5 hours of conventional training on bone model (model training group) or simulation TKA training on the computer-assisted orthopedic training system (CAOS training group). Participants were evaluated during a TKA based on a bone model at baseline, 1 week and 4 months after training.
Results: The CAOS training group performed the procedure significantly better than the other two groups at posttesting (P < 0.05). CAOS training group performing the procedure better than the model training group was identified at retention testing but this did not reach statistical significance.
Conclusion: These results indicated that this computer-assisted training system was able to produce the effect of learning TKA skill, and it could provide a training alternative for novices. Meanwhile, it could enhance student learning through increased motivation. |
