Introduction

The knee joint affects posture through the position of the hip joint. The knee joint is vulnerable to injuries. The bone’s structure is designed to provide mobility and weight bearing.

17-7

Bones

The tops of the medial and lateral tibial condyles are known as the medial and lateral tibial plateaus. The tibia bears most of the body’s weight in the knee joint. The fibula serves for an attachment site for muscles and ligaments.

Bones (cont.)

The patella is a sesamoid bone. Key bony landmarks include the tibial tuberosity, Gerdy’s tubercle, the medial and lateral femoral condyles, and the medial tibial condyle.

Joints

The knee joint is the tibiofemoral joint and is classified as a ginglymus joint because it acts like a hinge performing flexion and extension. Ligaments provide stability for the knee joint and the medial and lateral menisci (cartilage) cushion the joint.

Ligaments of the Knee Joint

The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) are named because they cross within the knee between the tibia and femur. The ACL is often injured. The medial knee has the tibial medial collateral ligament (MCL)

Ligaments of the Knee Joint (cont.)

The lateral side of the knee the fibular collateral ligament (LCL) joins the fibula to the femur. A plica is an anatomical variant among some individuals that may be irritated or inflamed with injuries or overuse of the knee. There are over 10 bursae in the knee.

Nerves

The femoral nerve innervates the knee extensors. The knee flexors are innervated by the tibial division of the sciatic nerve. The biceps femoris short head is supplied by the peroneal nerve.

Individual Muscles of the Knee Joint – Anterior - Quadriceps

The quadriceps consist of the rectus femoris, the vastus lateralis, vastus intermedius, and the vastus medialis. They all attach to the patella by the patellar tendon to the tuberosity of the tibia.
