Comparison of Clinical Joint Localization and Ultrasound-Confirmed Joint Positioning

This prospective, cross-sectional observational study aims to evaluate the differences between joint localizations determined by physicians based on physical examination and joint positions confirmed by musculoskeletal ultrasound. Knee, elbow, ankle, and wrist joints will be assessed in volunteer physicians working in Physical Medicine and Rehabilitation and Orthopedics and Traumatology. For each joint, participants will identify the joint space based on physical examination and the marked locations will be compared with ultrasound-confirmed joint positions. The distance between clinically determined and ultrasound-confirmed locations will be measured in millimeters. The study seeks to provide objective data on the accuracy of clinical joint localization and to support educational approaches in clinical anatomy and musculoskeletal examination training.
