Study Notes
- Patellar retinacular fibres are extensions of fibrous connective tissue.
- They have attachments to various parts of the knee.
- Tight retinaculum can have clinical implications and may require surgery.
- The lateral collateral ligament, popliteofibular ligament, popliteus tendon, and lateral meniscus reinforce the lateral capsule.
- The posterior capsule is reinforced by the oblique popliteal and arcuate popliteal ligaments.
- The medial collateral ligament and medial capsule are located in the middle 1/3 of the knee.
- The sartorius and gracilis tendons are cut to better expose the medial collateral ligament and medial capsule.
- The anterior 1/3 of the knee has medial patellar retinacular fibres.
- The posterior 1/3 of the knee has muscles.
- The popliteus muscle is located deep in the popliteal fossa.
Test your knowledge of the knee anatomy with this quiz that covers various attachments, ligaments, tendons, and capsules that reinforce the lateral and medial sides of the knee. Discover the clinical implications of tight retinaculum and the surgical procedures required to address them. Learn about the muscles located in the posterior 1/3 of the knee, including the deep popliteus muscle in the popliteal fossa. See if you can match the correct anatomical structures to their corresponding locations in the
