Figure 5e. Injuries of the LCLlateral collateral ligament Figure 5e. Injuries of the LCLlateral collateral ligament. (a, b) Coronal proton-density–weighted (a) and axial T2-weighted (b) fat-suppressed MR images in a 19-year-old female soccer player show an intact LCLlateral collateral ligament (straight arrow) with periligamentous edema (curved arrow in b), which is consistent with a strain (ie, grade I injury). (c, d) Coronal proton-density–weighted (c) and axial T2-weighted (d) fat-suppressed MR images in a 28-year-old man show a partial tear (ie, grade II injury) of the LCLlateral collateral ligament (arrow), as evidenced by the increased intrasubstance signal intensity and indistinctness of the anterior fibers of the proximal portion of the ligament (arrowhead in d). (e) Coronal proton-density–weighted fat-suppressed MR image in a 25-year-old man shows complete tears (grade III injuries) of both the LCLlateral collateral ligament (arrow) and the biceps femoris tendon (arrowhead), which are avulsed from the fibula.
