Musculoskeletal Anatomy (Lower Extremity)

The lower extremity includes the hip, knee, ankle, and foot with their weight-bearing joints, menisci, ligaments, tendons, and neurovascular structures. MRI is central to internal derangement and marrow assessment, complemented by radiographs, CT, and ultrasound. Recognizing meniscal and cruciate anatomy, ankle ligament complexes, and neurovascular courses is key to accurate musculoskeletal diagnosis.
