Study Notes

Basic Anatomy of the Knee

The knee joint has three main functions: altering the length of the lower extremity, providing stability during weight bearing, and enabling mobility for ambulation.

Bone Structure

The femur has two femoral condyles and an intercondylar groove.
The tibial plateau is another key component of the knee joint.
The fibula has no functional role in the main joints of the knee.

Patella and Joint Stability

The patella has posterior articular cartilage.
The knee joint is very stable due to the combined structure and function of these bones and cartilage.
