There is fluid around the lateral collateral ligament without increased signal within the ligament itself, compatible with type 1 sprain.,Medial and lateral menisci contain some minimal increased signal centrally that does not extend through an articular surface and findings are felt to represent minimal myxoid degeneration. No tear is seen. Anterior cruciate and posterior cruciate ligaments are intact. There is a bone bruise of medial patellar facet measuring approximately 8 x 5 mm. There is suggestion of some mild posterior aspect of the lateral tibial plateau.
