Fractures of the distal femur typically occur in the axial and sagittal planes. A Hoffa fracture is a coronal plane fracture of the femoral condyle, which accounts for 8.7% to 13% of distal femoral fractures. It is usually associated with other injuries around the knee joint and hence is often missed. We conducted a comprehensive systematic review of papers published in the English language using PubMed, Web of Science, Scopus, and the Cochrane Database, which reported Hoffa's fracture associated with other injuries around the knee joint. We selected 11 eligible papers for final analysis and review. These papers had 12 patients with Hoffa's fracture, with associated injuries around the knee joint. The associated injuries with Hoffa's fracture were in the ipsilateral distal femur, proximal tibia fractures, patellar dislocation, patella fracture, and patellar tendon incarceration. The management principles for Hoffa's fracture with associated injuries around the knee joint are: having a high clinical index of suspicion for these injuries, obtaining all trauma series radiographs and computed tomography of the knee, achieving complete articular incongruity, and restoring the functions of the knee joint.

Background: Accomplish a thorough review on the existing biomechanical and clinical studies about coronal plane fractures of the distal femur. Methods: We performed an electronic search of PubMed/MEDLINE database from April to June, 2023. The terms for the database search included “Hoffa fractures,” OR “Busch-Hoffa fractures” OR “coronal plane fractures of the distal femur.” Results: The search identified 277 potentially eligible studies. After application of inclusion and exclusion criteria, 113 articles were analyzed in terms of the most important topics related to coronal plane fractures of the distal femur. Conclusion: Lateral coronal plane fractures of the distal femur are more frequent than medial, present a more vertical fracture line, and usually concentrate on the weight bearing zone of the condyle. The Letenneur system is the most used classification method for this fracture pattern. Posterior-to-anterior fixation using isolated lag screws (for osteochondral fragments—Letenneur type 2) or associated with a posterior buttressing plate (when the fracture pattern is amenable for plate fixation—Letenneur types 1 and 3) is biomechanically more efficient than anterior-to-posterior fixation. Anterior-to-posterior fixation using lag screws complemented or not by a plate remains a widely used treatment option due to the surgeons’ familiarity with the anterior approaches and lower risk of iatrogenic neurovascular injuries. There is no consensus in the literature regarding diameter and number of screws for fixation of coronal plane fractures of the distal femur.

“…In these cases, the associated patellar fracture results from a combination of forces: direct trauma causing the Hoffa fracture and possible indirect injuries from sudden contraction of the quadriceps muscle causing a vertical patellar fracture. [23]…”

Hoffa fracture of the femoral condyle

et al. 2019

Background: Hoffa fractures are coronal-plane fractures of the femoral condyle, which are rarer than sagittal-plane condylar fractures. This study aimed to systematically review the clinical knowledge base of Hoffa fractures to facilitate the diagnosis and management of such injuries. Methods: We searched Medline, Embase, Cochrane Library, Google Scholar, China National Knowledge Infrastructure, and China Biology Medicine disc, using the terms “Hoffa fracture” and “coronal fracture of femoral condyle.” Results: One hundred five articles on Hoffa fractures were reviewed, and the clinical knowledge base was summarized. High-energy trauma is a common cause of a Hoffa fracture, although low-energy trauma and iatrogenic injury can also lead to these fractures. Commonly used classifications include the Letenneur classification, a computed tomography (CT) classification, the AO classification, and modified AO classification. Radiography can reveal fracture lines. If radiographic findings are negative in questionable cases, CT and magnetic resonance imaging (MRI) should be performed. Nondisplaced fractures can be managed conservatively; however, they involve a high risk of redisplacement. Open reduction and internal fixation are preferred. For young patients with good compliance, simple medial or lateral condylar fractures can be treated via a medial or lateral parapatellar approach. After fracture exposure, headless compression screws can be inserted perpendicularly to the fracture line from posterior to anterior. For bicondylar fractures, a median parapatellar incision can be used. For complex fractures in patients with osteoporosis or a high body mass index, cannulated screws with antigliding plate fixation should be used. Conclusion: Here, we summarized the injury mechanism, diagnosis, classification, and treatment options of Hoffa fractures.

A rare case of unicondylar medial Hoffa fracture associated with ipsilateral vertical patella fracture

Abstract: An 18 year old male patient was hit by a car to his motorcycle causing a unicondylar Hoffa fracture and an ipsilateral patella fracture. Hoffa fracture is a rare lesion and this association of injury has not been reported before.
