Adductor tubercle of femur

The adductor tubercle of the femur is a bony prominence located on the medial aspect of the femur, near the distal end of the bone. It serves as an important anatomical landmark and a point of attachment for the adductor magnus muscle.

Anatomy

The adductor tubercle is situated just above the medial epicondyle of the femur. It is a small, rounded projection that can be palpated through the skin in some individuals. The tubercle is part of the distal femur, which also includes the lateral epicondyle, the medial condyle, and the lateral condyle.

Function

The primary function of the adductor tubercle is to serve as the insertion point for the tendon of the adductor magnus muscle. The adductor magnus is one of the muscles in the medial compartment of the thigh, and it plays a crucial role in the adduction of the thigh. This muscle also assists in hip extension and medial rotation of the thigh.

Clinical Significance

The adductor tubercle is an important landmark in orthopedic surgery and physical examinations. It is often used as a reference point for the alignment of the femur during procedures such as total knee arthroplasty. Additionally, tenderness or pain around the adductor tubercle can be indicative of conditions such as adductor tendinopathy or medial knee pain.
