Association of Knee Ligament Injury with lpisilateral Femural Shaft Fructures

Background: Simultaneous knee ligament injury with femoral shaft fracture happens not infrequently such injuries could be missed on original evaluation of the broken limb. We are reporting the prevalence of such occurance in a group of isolated femur fractures. Materials and Methods: 63 cases of isolated femur fractures were entered into this study in an 11 month period. All these cases had a through examination of knee ligaments in the operating room following internal fixation of their femur fractures. Results: Among the 110 cases 80.6 percent were male. Their average age was 28.2 years and 69.3 percent were involved in motorcycle accident. 16 cases (25.8%) of ligamentous injury was observed which included 8 patients (12.9%) with medial collateral ligament (MCL) 5 (8.6%) posterior cruciate ligament (PCL) 2 (3.2%) lateral collateral ligament (LCL) and one (1.6%) anterior cruciate ligament (ACL) tear. Conclusion: Femoral shaft fructures, even in isolation are associated with high risk of ipisilateral knee ligament injuries. This is an important fact to remember when dealing with such fractures.
