The Hoffa fracture is an extremely rare injury of one or two condyles of the femur in the frontal plane, more often associated with injury to other structures of the knee joint area. The main cause of the Hoffa fracture is considered to be a high-energy injury (road accident in 80.5% of cases). The isolated Hoffa fracture accounts for 0.65% of all femoral fractures. To date, there is no consensus on surgical approach or optimal technique of internal fixation for the frontal fracture of the femoral condyles. There is also a large percentage of mistakes in the X-ray diagnosis of this pathology. The existing classifications have not found wide application in clinical practice, being difficult and inapplicable for solving the issue of treatment tactics and preoperative planning. The aim of the study is to present modern views on the diagnosis, principles and techniques of surgical treatment of patients with the Hoffa fractures based on the analysis of the literature. Based on the analyzed literature, conclusions are drawn about the need for careful collection of injury anamnesis, increased surgeon caution in the presence of this injury clinical picture and the simultaneous absence of pathology on standard knee joint X-rays, the need to perform an additional examination in the form of lateral (non-standard) projections of the knee joint X-rays, CT or MRI. During preoperative planning, preference should be given to minimally invasive technologies, including arthroscopically-associated methods of treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
