Improving Resident Performance in Knee Arthroscopy: A Prospective Value Assessment of Simulators and Cadaveric Skills Laboratories.

Cadaveric skills laboratories and virtual reality simulators are two common methods used outside of the operating room to improve residents' performance of knee arthroscopy. We are not aware of any head-to-head comparisons of the educational values of these two methodologies. The purpose of this prospective randomized trial was to assess the efficacy of these training methods, compare their rates of improvement, and provide economic value data to programs seeking to implement such technologies. Orthopaedic surgery residents were randomized to one of three groups: control, training on cadavera (cadaver group), and training with use of a simulator (simulator group). Residents completed pretest and posttest diagnostic knee arthroscopies on cadavera that were timed and video-recorded. Between the pretest and posttest, the control group performed no arthroscopy, the cadaver group performed four hours of practice on cadavera, and the simulator group trained for four hours on a simulator. All tests were scored in a blinded, randomized fashion using the validated Arthroscopy Surgical Skill Evaluation Tool (ASSET). The mean improvement in the ASSET score and in the time to complete the procedure were compared between the pretest and posttest and among the groups. Forty-five residents (fifteen per group) completed the study. The mean difference in the ASSET score from the pretest to the posttest was -0.40 (p = 0.776) in the control group, +4.27 (p = 0.002) in the cadaver group, and +1.92 (p = 0.096) in the simulator group (p = 0.015 for the comparison among the groups). The mean difference in the test-completion time (minutes:seconds) from the pretest to the posttest was 0:07 (p = 0.902) in the control group, 3:01 (p = 0.002) in the cadaver group, and 0:28 (p = 0.708) in the simulator group (p = 0.044 for the comparison among groups). Residents in the cadaver group improved their performance at a mean of 1.1 ASSET points per hour spent training whereas those in the simulator group improved 0.5 ASSET point per hour of training. Cadaveric skills laboratories improved residents' performance of knee arthroscopy compared with that of matched controls. Residents practicing on cadaveric specimens improved twice as fast as those utilizing a high-fidelity simulator; however, based on cost estimation specific to our institution, the simulator may be more cost-effective if it is used at least 300 hours per year. Additional study of this possibility is warranted.

Improving residency training in arthroscopic knee surgery with use of a virtual-reality simulator. A randomized blinded study.

There is a paucity of articles in the surgical literature demonstrating transfer validity (transfer of training). The purpose of this study was to assess whether skills learned on the ArthroSim virtual-reality arthroscopic knee simulator transferred to greater skill levels in the operating room. Postgraduate year-3 orthopaedic residents were randomized into simulator-trained and control groups at seven academic institutions. The experimental group trained on the simulator, performing a knee diagnostic arthroscopy procedure to a predetermined proficiency level based on the average proficiency of five community-based orthopaedic surgeons performing the same procedure on the simulator. The residents in the control group continued their institution-specific orthopaedic education and training. Both groups then performed a diagnostic knee arthroscopy procedure on a live patient. Video recordings of the arthroscopic surgery were analyzed by five pairs of expert arthroscopic surgeons blinded to the identity of the residents. A proprietary global rating scale and a procedural checklist, which included visualization and probing scales, were used for rating. Forty-eight (89%) of the fifty-four postgraduate year-3 residents from seven academic institutions completed the study. The simulator-trained group averaged eleven hours of training on the simulator to reach proficiency. The simulator-trained group performed significantly better when rated according to our procedural checklist (p = 0.031), including probing skills (p = 0.016) but not visualization skills (p = 0.34), compared with the control group. The procedural checklist weighted probing skills double the weight of visualization skills. The global rating scale failed to reach significance (p = 0.061) because of one extreme outlier. The duration of the procedure was not significant. This lack of a significant difference seemed to be related to the fact that residents in the control group were less thorough, which shortened their time to completion of the arthroscopic procedure. We have demonstrated transfer validity (transfer of training) that residents trained to proficiency on a high-fidelity realistic virtual-reality arthroscopic knee simulator showed a greater skill level in the operating room compared with the control group. We believe that the results of our study will stimulate residency program directors to incorporate surgical simulation into the core curriculum of their residency programs.

Ankle Arthroscopy Simulation Improves Basic Skills, Anatomic Recognition, and Proficiency During Diagnostic Examination of Residents in Training.

The purpose of this study was to determine whether low-fidelity arthroscopic simulation training improves basic ankle arthroscopy performance and efficiency among orthopedic trainees. Twenty-nine orthopedic surgery trainees with varying levels of experience in ankle arthroscopy were randomized into either simulation or standard practice groups. At baseline testing, all participants performed simulator-based testing and a cadaveric diagnostic ankle arthroscopy with video recording. The simulation group subsequently received 4 one-on-one, 15-minute simulation training sessions over a 4-month period, while the standard practice group received no additional simulation training or exposure. After intervention, both groups were reevaluated with simulator testing and a second recorded cadaveric diagnostic ankle arthroscopy. Two blinded, independent experts evaluated each randomized arthroscopic performance using the 15-point checklist, Arthroscopic Surgery Skill Evaluation Tool (ASSET), and total elapsed time, and all outcome measures were compared within and between groups. Baseline arthroscopic experience, simulator task performance measures, and ASSET scores were equivalent between the simulation and standard practice groups. After completion of training, the simulation group outscored the control group in total ASSET score (34.9 vs 19.6; P < .001) and checklist score (14.5 vs 8.4; P < .001) and achieved nearly expert ASSET Safety scores (4.7 vs 2.9; P < .001) on the simulator model. Cadaver testing also demonstrated significant improvements in total ASSET score (28.8 vs 16.8; P < .001), checklist score (12.6 vs 7.1; P < .001), and ASSET Safety score (3.9 vs 2.6; P < .001). These results demonstrate that low-fidelity ankle arthroscopy simulation training can improve basic surgical skills, efficiency of movement, and anatomic recognition. The results suggest greater patient safety during ankle arthroscopy following simulation training. Level I, prospective comparative study.

Arthroscopy skills development with a surgical simulator: a comparative study in orthopaedic surgery residents.

Surgical simulation has become increasingly relevant to orthopaedic surgery education and could translate to improved operating room proficiency in orthopaedic surgery trainees. To compare the arthroscopic performance of junior orthopaedic surgery residents who received training with a knee and shoulder arthroscopy surgical simulator with those who received didactic training. Controlled laboratory study. Fourteen junior orthopaedic surgery residents at a single institution were randomized to receive knee and shoulder arthroscopy training with a surgical simulator (n = 8) or didactic lectures with arthroscopy models (n = 6). After their respective training, performance in diagnostic knee and shoulder arthroscopy was assessed using a cadaveric model. Time to completion and assessment of arthroscopic handling using a subjective injury grading index (scale, 1-10) was then used to evaluate performance in final cadaveric testing. Orthopaedic surgery residents who trained with a surgical simulator outperformed the didactic-trained residents in shoulder arthroscopy by time to completion (-35%; P = .02) and injury grading index (-35%; P = .01). In addition, a trend toward improved performance of knee arthroscopy by the simulator-trained group was found by time to completion (-36%; P = .09) and injury grading index (P = .08). In this study, junior orthopaedic surgery residents who trained with a surgical simulator demonstrated improved arthroscopic performance in both knee and shoulder arthroscopy. However, future validation of surgical simulator training for orthopaedic surgery residents remains warranted. Surgical skill development with an arthroscopy surgical simulator could translate to improved arthroscopy performance in the operating room.
