Abstract

Abstract : Background: Virtual reality and cadaveric simulations are expensive and not readily accessible1 . Innovative and accessible training adjuncts are required to help meet training needs. Cognitive task analysis (CTA) has been used extensively to train pilots and surgeons in other surgical specialties2 -6 . However, the use of CTA tools within orthopaedics is in its infancy. Arthroscopic procedures are minimally invasive and require a different skill set compared with open surgery. Residents often feel poorly prepared to perform this in the operating room because of the steep learning curve associated with acquiring basic arthroscopic skills. We designed the Imperial Knee Arthroscopy Cognitive Task Analysis (IKACTA) tool, which is, to our knowledge, the first CTA tool described in the orthopaedic literature, demonstrating significant objective benefits in training novices to perform diagnostic knee arthroscopy. Description: The IKACTA tool, which is the combination of the written description of the phases below and the videos (with superimposed audio recordings) of each phase, utilizes simultaneous written and audiovisual modalities to teach diagnostic knee arthroscopy. The procedure was divided into 7 phases: (1) operating room and patient setup, (2) preparation and draping, (3) anterolateral portal placement, (4) examination of the patellofemoral joint and the lateral gutter, (5) examination of the medial compartment and anteromedial portal placement, (6) examination of the intercondylar notch and the lateral compartment, and (7) postoperative care and rehabilitation. For each phase, there are sections on the technical steps, cognitive decision-making behind each technical step, and potential errors and solutions. Video clips recorded by an expert surgeon in the operating room specific to each phase and audio voice recordings explaining each phase superimposed on the video clips were combined with the written information to design the IKACTA tool. Alternatives: Not applicable. Rationale: This learning tool allows a trainee to learn each technical step, the cognitive decision-making underpinning each step, and potential errors and solutions relevant to each phase of the procedure. Furthermore, the learner can use written and audiovisual modalities simultaneously to learn this technique by reading the written component of the tool first and then watching the relevant video clips with the audio recordings for each phase of the procedure. Alternative training techniques currently include the traditional apprenticeship model, which is becoming increasingly insufficient in the current environment of reduced training hours7, 8 . Adjuncts to this model are essential to help meet training needs. The IKACTA tool has demonstrated significant objective benefits for novice trainees to learn diagnostic knee arthroscopy9 . The idea behind this learning tool is for the trainee surgeon to use this tool independent of the trainer, prior to attending the operating room. The tool provides trainees with knowledge and cognitive understanding of the procedural steps before they perform this procedure on patients. They are aware of potential errors and methods to avoid or overcome these errors. We believe that this tool will reduce the initial difficult phase of the learning curve for junior residents and, therefore, will improve training efficiency in the operating room.
