Background: Previous studies of task-specific skills have suggested that a loss technical performance occurs if the skill is not practiced for six-month period. The aims this study were to objectively demonstrate learning curve complex arthroscopic task (meniscal repair) by means motion analysis and determine impact repetition on retention skill. Methods: Nineteen orthopaedic residents with experience in routine knee arthroscopy but meniscal repair recruited into randomized study. During initial phase, all subjects performed twelve repairs simulator over three-week A validated tracking system was used record each subject; outcomes time taken, distance traveled, number hand movements. then three groups. Group one month, B at months, C no during interim phase. All groups returned point final assessment which they carried out an additional weeks. Results: demonstrated clear significant objective improvement parameters episodes (p < 0.0001). Although some had reached plateau episodes, others continued make further improvements up another nine episodes. Importantly, did display any between phase evaluation despite break > 0.05). Conclusions: In contrast previous studies, lose interruption performance, other took longer produce more consistent performance. Clinical Relevance: These findings suggest presence surgical group-specific factors affect skills. use generic guidelines minimum frequency maintaining optimal tasks surgeons may be appropriate.
