摘要
Purpose: To investigate whether acquiring basic knee arthroscopic skills via a spaced retraining schedule could prevent skills deterioration and achieve further skills improvement. Methods: In the learning phase, 16 residents with no previous hands-on experience in practicing arthroscopic skills were asked to perform basic arthroscopic tasks on a simulator until they attained perfect scores in each task. Immediately after completing the learning phase, a pretest was performed to assess their performance. Next, they were randomly assigned into 2 groups. The spaced retraining group, which undertook a spaced repetitive training phase with a fixed-time interval, returned on days 2, 4 and 6 to repeat the same tasks for 20 minutes per day, whereas the control group did nothing. On day 7, all participants performed a posttest. A 2 x 2 mixed analysis of variance model was used for statistical analysis. Results: Significant differences between the 2 groups were found in task completion time (P = .003) and camera path length (P = .043) but not cartilage injury (P = .186). Residents in the spaced retraining group decreased their task completion time (163.2 +/- 23.9 seconds) whereas the task time in the control group increased (351.3 +/- 25.5 seconds). The same pattern was found with the camera path length. Conclusions: Implementing a spaced retraining schedule in 1 week resulted in a reduced task completion time and camera path length but no significant reduction in cartilage injury. It appears that introducing a spaced retraining schedule to retain arthroscopic skills acquired through massed learning may be advantageous.
