AN18.1-7 | Introduction to Knee joint, Anterior compartment of leg & dorsum of foot
Learning Objectives
- Describe the muscles of the anterior compartment of the leg with their attachments, nerve supply, and actions (AN18.1)
- Trace the deep peroneal nerve and anterior tibial/dorsalis pedis arteries through the anterior compartment (AN18.2)
- Explain the anatomical basis of foot drop — which nerve, which muscles, what movements are lost (AN18.3)
- Describe the knee joint — type, articular surfaces, capsule, ligaments, movements, nerve supply, and anastomosis around the knee (AN18.4)
- Explain the locking and unlocking mechanism of the knee joint with the role of popliteus (AN18.5)
- Describe knee joint injuries — unhappy triad, anterior drawer test, medial collateral ligament tears, and their anatomical basis (AN18.6)
- Explain the anatomical basis of osteoarthritis of the knee with its radiological and clinical correlates (AN18.7)
INSTRUCTIONS
This module covers three linked regions: the anterior leg, the dorsum of the foot, and the knee joint. The knee joint section is the most detailed — it is a high-yield topic for both examinations and clinical practice. Complete each self-check before proceeding.
