    ObjectiveTo compare compression screws and buttress plate (CS plus BP) with compression screws only (CS) in treating patients with Hoffa fracture.MethodsThis retrospective study included Chinese patients with Hoffa fracture treated by open reduction and internal fixation. Radiographs and clinical outcomes (range of movement [ROM], bone union and Knee Society Score [KSS]) were compared between patients treated using CS plus BP versus CS only.ResultsAt 4 months following surgery, significantly better outcomes were shown in the CS plus BP group ( n = 24) versus CS only group ( n = 21) regarding ROM (120.4 ± 5.2° versus 110 ± 7.1°) and KSS (85.5 ± 4.1 versus 79.7 ± 3.3). At the 12-month follow-up, significantly better outcomes were maintained in the CS plus BP versus CS only group regarding ROM (126.2 ± 7.4° versus 120.5 ± 8.2°) and KSS (88.3 ± 4.6 versus 84.2 ± 4.0). At the final follow-up, all patients had normal fracture healing and no malunion, nonunion or reduction loss.ConclusionsFixation with CS plus BP for Hoffa fracture is effective and reliable, and may provide more adequate stability and better outcomes versus CS only.
