Outcome and affecting factors of distal femoral fractures treated by less invasive stabilization system

Abstract

Objective To assess the outcome and affecting factors of distal femoral fractures treated by less invasive stabilization system(LISS).Methods Between January 2009 and November 2012,81 patients with distal femoral fractures were treated by LISS.The outcome was evaluated by clinical function and radiographic results.A statistical model was constructed comprising the clinical outcome and the postulated prognostic factors.The association between these factors and outcome was explored by Logistic regression.Results Eighty one patients were followed up for average 18.2 months(14-21months).The average knee range motion was 109.1° in type A and 101° in type C.A satisfactory outcome(excellent and good results) was achieved in 32 of 35 type A factures(91.4%)and 33 of 46 type C fracture(71.7%).Logistic regression analysis showed that the fracture type,whether or not early functional exercise,and whether or not complications happened were major factors in the knee joint function recovery.Conclusion LISS is a useful option for distal femoral fractures.Patients must do early functional exercise and decrease complications to improve the knee function.
