Operative Management of Hoffa Fracture of the Femoral Condyle
Hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur and only very few cases have been reported in the literature. These fractures are due to high energy trauma and conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of complications. The purpose of the study was to prospectively analyse the clinico-radiological and functional outcome following open surgical treatment. From July 2005 to July 2010, 22 patients (14 males and 8 females) were recruited from Emergency and outpatient department having closed and open Hoffa fracture of the femoral condyle. All patients were operated under general or spinal anesthesia. Post-operatively, all the patients were followed for 12 months. Fractures were united in a mean time of 10 weeks (range from 6 - 16 weeks) depending on the type of fracture pattern. Fractures were reduced anatomically in all except in one patient. During follow-up, there were no losses of reduction or fixation. Full weight bearing were started in the mean time of 8.8 weeks. Mean duration of hospital stay were 9.8 days. Complications were stiffness and pain in one patient, collateral laxity in one patient and progression of arthritis in one patient. The results were excellent in 90.90% and good in 9.09% patients. Finally, we conclude that the early anatomical reduction and rigid fixation with screws provide best results and minimal complications.
