title: Validation of a Dry Model for Assessing the Performance of Arthroscopic Hip Labral Repair.
abstract: BACKGROUND
  Arthroscopic hip labral repair is a technically challenging and demanding surgical technique with a steep learning curve. Arthroscopic simulation allows trainees to develop these skills in a safe environment.
  
  
  OBJECTIVE
  The purpose of this study was to evaluate the use of a combination of assessment ratings for the performance of arthroscopic hip labral repair on a dry model.
  
  
  METHODS
  Cross-sectional study; Level of evidence, 3.
  
  
  METHODS
  A total of 47 participants including orthopaedic surgery residents (n = 37), sports medicine fellows (n = 5), and staff surgeons (n = 5) performed arthroscopic hip labral repair on a dry model. Prior arthroscopic experience was noted. Participants were evaluated by 2 orthopaedic surgeons using a task-specific checklist, the Arthroscopic Surgical Skill Evaluation Tool (ASSET), task completion time, and a final global rating scale. All procedures were video-recorded and scored by an orthopaedic fellow blinded to the level of training of each participant.
  
  
  RESULTS
  The internal consistency/reliability (Cronbach alpha) using the total ASSET score for the procedure was high (intraclass correlation coefficient > 0.9). One-way analysis of variance for the total ASSET score demonstrated a difference between participants based on the level of training ( F3,43= 27.8, P < .001). A good correlation was seen between the ASSET score and previous exposure to arthroscopic procedures ( r = 0.52-0.73, P < .001). The interrater reliability for the ASSET score was excellent (>0.9).
  
  
  CONCLUSIONS
  The results of this study demonstrate that the use of dry models to assess the performance of arthroscopic hip labral repair by trainees is both valid and reliable. Further research will be required to demonstrate a correlation with performance on cadaveric specimens or in the operating room.
