Hoffa Fractures: Current Understanding and Surgical Treatment Strategies

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Coronal fractures of the distal femur, known as Hoffa fractures, are distinct from other distal femur fractures.
• These injuries involve obliquely oriented fracture lines in the coronal plane, often affecting the lateral condyle due to shearing forces with the knee flexed.
• Previously difficult to detect on plain radiographs, Hoffa fractures are now more readily identified with CT scans.

Purpose of the Study:

• To review and outline strategies for the surgical management of Hoffa fractures.
• To discuss the outcomes and complications associated with these fractures based on published evidence.

Main Methods:

• Literature review of published evidence on Hoffa fractures.
• Analysis of surgical approaches, reduction techniques, and fixation methods.
• Evaluation of outcomes and complications reported in existing studies.

Main Results:

• Hoffa fractures require anatomical reduction and stable fixation to enable early knee motion and prevent arthrofibrosis.
• Optimal surgical management depends on understanding fracture patterns, comminution, impaction, and fragment characteristics.
• Associated proximal skeletal injuries can lead to delayed diagnosis of Hoffa fractures.

Conclusions:

• Effective surgical treatment of Hoffa fractures necessitates a thorough understanding of fracture morphology and patient-specific factors.
• Careful surgical planning is essential for achieving anatomical reduction and stable fixation.
• Early knee mobilization and prevention of arthrofibrosis are key goals in managing these injuries.
