A Comparative Study of Functional and Radiological Outcome of Hoffa Fracture Treated with Cannulated Cancellous Screw (CCS) and Buttressing Plate versus Cannulated Cancellous Screw Alone

Purpose and objective: Hoffa fracture is a femoral condyle fracture in the coronal plane. The lateral condyle is more commonly involved. This study aimed to compare the functional and radiological results of surgical treatment for Hoffa fractures with CCS and buttressing plate versus CCS alone. Methodology: This was a prospective study conducted from March 2023 to march 2024 in orthopaedic department of Gauhati Medical College and Hospital, Assam. This study includes 20 patients with Hoffa fracture out of which 10 treated with CCS and buttressing plate and other 10 treated with CCS alone. Radiological and functional outcome, Range of motion (ROM) and knee society score (KSS) of patients were evaluated at the 4- and 12-month follow-up examination. Results: 4 months after the surgery, markedly improved outcomes were observed in the CCS and buttressing plate group vs CCS group regarding ROM (122 +/-5 vs 110+/-8) AND KSS (85 +/-5 vs 78 +/-4). In the 12 months follow-up after surgery, significantly improved outcomes were sustained in the CCS with buttressing plate vs CCS group regarding ROM (128+-5 vs 122+-5) and KSS (89+/-5 vs 83+/-4). By the final follow-up, all patients had achieved normal healing with no instances of malunion, non-union or reduction loss. Conclusion: Fixation of Hoffa fracture with CCS and buttressing plate is more effective and reliable as compared to CCS alone.
