Summary

This lesson introduces the knee structures that support stability, explains the ACL’s role, and describes how ACL injuries occur.

The knee joint is formed by the femur (thighbone), tibia (shinbone), and patella (kneecap). Ligaments are strong bands of connective tissue that help hold bones together and stabilize the joint.

The medial and lateral menisci are C-shaped cartilage structures resting on the tibia. They cushion the bones and may be injured along with the ACL.

All flashcards

Hemarthrosis
Bleeding into a joint; after an ACL injury, it can contribute to rapid knee swelling.
Pivot shift
A shifting sensation associated with abnormal movement of the tibia as the knee bends after ACL rupture.
Prehabilitation
Exercise and preparation before surgery, often focused on knee motion, swelling, and quadriceps strength.
Autograft
A graft taken from the patient's own body for ACL reconstruction.
Return-to-sport readiness
An assessment that considers strength, functional performance, movement quality, and psychological readiness.
