Abstract Body :
Introduction: This study offers a unique perspective on medical education, with a primary focus on employing donor bodies to gain an intricate understanding of knee joint anatomy and its clinical implications. Objective: The objective is to use cadaveric dissection to identify specific vasculature and nerves to avoid and meticulously delineate joint spaces and landmarks to target when performing knee joint injections. This knowledge is pivotal for medical students to confidently approach knee joint procedures in clinical settings.Materials and Methods: Cadaveric dissection was completed centered on the knee joint. The exploration encompassed a meticulous identification of anatomical structures, with a particular emphasis on the location of key vasculature and nerves to be avoided during knee joint injections. The intra-articular joint space was identified which served as the primary target for therapeutic interventions using the superolateral, superomedial, anteromedial, and anterolateral injection approaches. The dissection method strictly adhered to standardized procedures and stringent safety guidelines.Results: The study yielded an intricate comprehension of knee joint anatomy in the context of clinical procedures. Vasculature and nerves were meticulously identified in relation to the knee joint. Furthermore, the crucial joint spaces were identified, distinguishing the intra-articular compartments like the suprapatellar bursa and synovial cavity, as well as the peri-articular spaces, including the infrapatellar fat pad and tendons. These detailed findings enable precise planning and execution of knee joint injections, minimizing risks and optimizing therapeutic outcomes.Conclusion: From the perspective of a medical student, the "first patient" experience utilizing cadaveric dissection to comprehend knee joint anatomy and injection sites is a profound educational opportunity. It bridges the gap between theoretical knowledge and clinical proficiency, instilling the ability to both identify critical vasculature and confidently navigate the intricacies of knee joint spaces for therapeutic interventions.Significance/Implication: This research underscores the paramount significance of hands-on cadaveric dissection in medical education. The in-depth knowledge acquired regarding knee joint anatomy and precise injection sites directly translates into safer and more efficacious clinical procedures. By advocating for the integration of this immersive learning approach into medical curricula, we can better equip future healthcare professionals, ultimately enhancing patient care and clinical outcomes.
