What is the Trochlear groove?

What is the Trochlear groove?

The trochlea is a groove in the femur bone underneath the kneecap (patella). The walls of the trochlea stabilize the patella and allow it to glide down the center of the trochlea as the knee bends.

Why is the Trochlear groove important?

The trochlear groove plays a major role in the mechanics and pathomechanics of the patellofemoral joint [13, 14, 21]. After knee arthroplasty, one of the determinants in the patellofemoral mechanism is the design of the prosthetic trochlear groove [17].

What is a femoral groove?

The underside of the patella is covered with articular cartilage, the smooth, slippery covering found on joint surfaces. This covering helps the patella glide (or track) in a special groove made by the thighbone, or femur. This groove is called the femoral groove.

What is a shallow trochlea?

The most proximal extent of the trochlea (the portion encountered by the patella in early flexion) is the shallowest and therefore offers the least stability to the patella. While articulating with this portion of the trochlea, the patella is most susceptible to dislocation.

Is Trochlear dysplasia rare?

Is trochlear dysplasia rare? Severe cases of trochlear dysplasia are rare, whereas more mild cases where the trochlear groove may be flatter than normal, are not that uncommon. Therefore, it is a relatively common condition, but often does not cause significant problems when it is a milder case of trochlear dysplasia.

What is Trochlea of femur?

Description. The trochlea of femur (femoral trochlea) is the cranial cartilaginous part of distal femur, for articulation with the patella fo form the femoral patellar joint. It consists of a groove bounded by the medial and a lateral ridges.

What is trochlear depth?

The trochlear depth is calculated by measuring the mean of the maximum anteroposterior (AP) distance of the medial and lateral femoral condyles minus the distance between the deepest point of the trochlear groove and the line paralleling the posterior femoral condyles surfaces (Fig. 1).

Where is the Trochlear groove located?

The trochlear notch (/ˈtrɒklɪər/), also known as semilunar notch and greater sigmoid cavity, is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint.
