Best Practice Case Studies-Knee Lateral Collateral Ligament Tear

Video Transcription

Video Summary

An 18-year-old football player sustained a left knee injury. Radiographs revealed a non-displaced fibular head fracture. Stress tests showed asymmetric widening in the lateral knee compartment, though this isn't routinely performed in emergencies. MRI indicated a subtle sprain of the fibular collateral ligament and posterior lateral corner injury, with bone contusion in the medial femoral condyle and tibial plateau. Another patient comparison revealed a medial collateral ligament tear visible on imaging. The findings include edema, consistent with a grade 2 or 3 sprain, depending on the presence and intensity of the edema and fiber irregularities.
