Abstract Purpose To evaluate the incidence, morphology, and associated complications of medial cortical hinge fractures after lateral closing wedge distal femoral osteotomy (LCW-DFO) for varus malalignment and to identify constitutional and technical factors predisposing for hinge fracture and consecutive complications. Methods Seventy-nine consecutive patients with a mean age of 47 ± 12 years who underwent LCW-DFO for symptomatic varus malalignment at the authors’ institution between 01/2007 and 03/2018 with a minimum of 2-year postoperative time interval were enrolled in this retrospective observational study. Demographic and surgical data were collected. Measurements evaluating the osteotomy cut (length, wedge height, hinge angle) and the location of the hinge (craniocaudal and mediolateral orientation, relation to the adductor tubercle) were conducted on postoperative anterior–posterior knee radiographs and the incidence and morphology of medial cortical hinge fractures was assessed. A risk factor analysis of constitutional and technical factors predisposing for the incidence of a medial cortical hinge fracture and consecutive complications was conducted. Results The incidence of medial cortical hinge fractures was 48%. The most frequent morphological type was an extension fracture type (68%), followed by a proximal (21%) and distal fracture type (11%). An increased length of the osteotomy in mm (53.1 ± 10.9 vs. 57.7 ± 9.6; p = 0.049), an increased height of the excised wedge in mm (6.5 ± 1.9 vs. 7.9 ± 3; p = 0.040) as well as a hinge location in the medial sector of an established sector grid (p = 0.049) were shown to significantly predispose for the incidence of a medial cortical hinge fracture. The incidence of malunion after hinge fracture (14%) was significantly increased after mediolateral dislocation of the medial cortical bone > 2 mm (p < 0.05). Conclusion Medial cortical hinge fractures after LCW-DFO are a common finding. An increased risk of sustaining a hinge fracture has to be expected with increasing osteotomy wedge height and a hinge position close to the medial cortex. Furthermore, dislocation of a medial hinge fracture > 2 mm was associated with malunion and should, therefore, be avoided. Level of evidence Prognostic study; Level IV.

Articular Fractures

Hoffa fractures are unstable intra-articular fractures of the femoral condyle that occur in the coronal plane.Insufficient anatomical reduction and internal fixation may lead to non-union or malunion. A 39-year-old man was involved in a traffic accident while riding a motorcycle and was diagnosed with left Hoffa fracture and avulsion fracture of the femoral attachment of the medial collateral ligament. Open reduction and internal fixation were performed 5 days after injury. The patient experienced intermittent knee pain, joint contracture and deformity, and attended our hospital for further treatment 18 months after surgery. CT revealed depression and malunion of the posterior aspect of the lateral femoral condyle, and weight-bearing X-ray showed valgus deformity due to malunion. Distal femoral osteotomy (DFO) was performed and good functional and radiographic results were obtained. This report suggests that DFO is a reasonable treatment for young patients suffering from malalignment due to malunited Hoffa fracture.
