Abstract

INTRODUCTION: Coronal plane femoral condyle fractures (Hoffa fracture) are more common in young adults as a result of high velocity road traffic accidents&falls. The incidence of Hoffa fracture is 8.7 to 13%. Early surgical intervention of Hoffa fractures hastens the fracture union, initiates early ambulation thereby decreasing the morbidity of patients. AIM OF THE STUDY: The aim of this study is to analyze the functional outcome of coronal plane fracture of femoral condyle (Hoffa fracture) treated with cannulated cancellous screws. MATERIALS & METHODS: Patients diagnosed as Hoffa fracture by X ray & CT were included in the study. After complete evaluation all fractures were treated by open reduction & internal fixation with cannulated cancellous screws. On follow up clinical and radiological evaluation was done by knee society score and disappearance of fracture line respectively. OBSERVATIONS & RESULTS: Out of 20 patients, common age group was 20-30 years. Male(16) outnumbered females (4) and all 20 sustained injury due to RTA. 8 of them had associated injuries like tibial plateau injury (3), pubic rami injury (2), patella (2), distal femur (1). The most common condyle involved was lateral condyle (18). Most fell into letenneur type 1 (16) subjects. The mean duration union noted was 12+ 2 weeks. Radiological union was obtained at the end of 3 months in 18 cases. 2 cases had delayed union. 13 Subjects had KSS between 80- 100 with excellent results. 3 subjects had good results (70-79) & 2 subjects (60-69). 2 Subjects yielded knee society score less than 60 with poor results. 90% of the study population had met none of the complications. 2 out of 20 had delayed union and screw pull out due to infection respectively who yielded poor functional outcome with knee society score less than 60. DISCUSSION: In this study radiological union noted was 12+ 2 week and mean KSS was 81.5. But a study by Singh R [et. al.] observed a longer duration of union (16 weeks) & noted mean KSS of 87.5 + 10.4. Apart from delayed union and infection complications noted in this study no other complications like stiffness, avascular necrosis are observed which was seen in study by vivek trikha [et. al.]. CONCLUSION: As this study shows excellent functional outcome of Hoffa fracture treated with only cancellous screws thereby quotes with the help of cancellous screw fixation Hoffa fracture can be treated effectively. So timely diagnosis and surgical treatment using cannulated cancellous screw effectively manages Hoffa fracture rather being unnoticed.
