What is intercondylar eminence?

The intercondylar eminence is the raised area on the proximal tibial surface between articular facets.

Does ACL avulsion require surgery?

Conclusion. This study shows that ACL avulsion fracture can be treated effectively by arthroscopic suture fixation with fiber wires. In fact, this technique may restore knee function and stability.

What causes intercondylar eminence?

Intercondylar eminence fractures in skeletally immature patients usually result from injuries that would cause ACL tears in skeletally mature patients. Meyers and McKeever reported that a large number of bicycle falls produce this type of injury in children.

What is eminence fracture?

The tibial eminentia avulsion fracture (TEAF) is an injury most commonly seen in skeletally immature patients, and it is the paediatric equivalent to a midsubstance an terior cruciate ligament (ACL) injury.

Where is the intercondylar notch located?

The intercondylar fossa of femur (intercondyloid fossa of femur, intercondylar notch of femur) is a deep notch between the rear surfaces of the medial and lateral epicondyle of the femur, two protrusions on the distal end of the femur (thigh bone) that joins the knee.

What is the function of intercondylar fossa?

Surrounded on either side by two large, bony protrusions, the intercondylar fossa (or intercondylar notch) presents as a dent or indentation on the end of the thigh bone. This intercondylar groove serves as an important structure for various ligaments that compose the knee and assist with the femur’s function.

How do you fix ACL avulsion?

Different types of fixation for ACL avulsions include cancellous screws, staples, sutures, K wires to bio- absorbable suture anchors. The conservative method carries its complications of prolonged immobilization, knee stiffness, and residual instability.

Where is the intercondylar notch in the knee?

What is PCL avulsion fracture?

Posterior cruciate ligament (PCL) avulsion fractures are a type of avulsion fracture of the knee that represent the most common isolated PCL lesion. This typically involves the separation of the posterior tibial insertion of the PCL to variable degrees.

What is the function of the intercondylar notch?

Function of the Intercondylar Fossa As it was mentioned before, the intercondylar fossa helps to stabilize the knee joint. The reason why this groove at the bottom rear of the femur helps to stabilize the knee joint is that it is home to several ligaments of the knee.

What is the relationship between intercondylar eminence and ACL microtearing?

Some controversy exists as to whether microtearing of the ACL is associated with an intercondylar eminence fracture and results in ACL laxity despite anatomic fixation of the fracture. [ 7] Intercondylar eminence fractures can extend into either of the articular tibial plateaus.

What is the pathophysiology of intercondylar eminence fractures?

Pathophysiology. Intercondylar eminence fractures can extend into either of the articular tibial plateaus. Associated meniscal or ligamentous injuries, such as a medial collateral ligament tear, also are possible. These types of complicating injuries are more often observed in adults, who frequently sustain higher-energy trauma (ie,…

What is the future of surgical management of intercondylar eminence fractures?

Although adults also can sustain this type of injury, they will often have additional concurrent knee trauma and, despite anatomic reduction, frequently do poorly. The future of surgical management of displaced intercondylar eminence fractures is the arthroscopic approach.

What is the Meyer and McKeever classification of intercondylar eminence fractures?

Meyers and McKeever classification of type I, II, and III intercondylar eminence fracture injuries. The tibial eminence consists of the eminent confluence of the tibial plateaus and contains two spines.
