Video Summary

In this video, Dr. Rohan Bhimani discusses the influence of femoral length and lateral knee x-rays on the accuracy of radiographic landmarks for MPFL complex reconstruction. The study included nine unpaired cadaveric knees without knee OA, ligamentous instability, or previous injuries. Lateral fluoroscopic images were obtained at different visible femoral lengths, and the MPFC midpoint was measured relative to the posterior cortical line of the femur. Results showed that the MPFC moved anteriorly as visible femoral length decreased. Linear regression analysis revealed that for every one centimeter decrease in femoral length, the MPFC moved anteriorly by 0.6 millimeters. The visible femoral length should be at least four centimeters to accurately localize femoral tunnel positioning. These findings can guide surgeons during MPFC reconstruction using fluoroscopy.
