Abstract
INTRODUCTION: Klippel-Trenaunay syndrome is a rare congenital disorder. Injuries involving the posterior cruciate ligament (PCL) may occur independently following trauma. We're reporting this rarest combination, the first case reported in literature, where these two conditions occur in the same limb. CASE REPORT: We present a 23-year-old male with sports injury to the right knee 3 years back who was diagnosed with PCL injury clinicoradiologically. Port wine stain, limb hypertrophy, and varicose veins were noticed in the affected limb and were diagnosed as Klippel-Trenaunay syndrome. He underwent arthroscopic PCL reconstruction. CONCLUSION: There is limited direct evidence of PCL injuries specifically in Klippel-Trenaunay patients, but given the limb overgrowth and potential instability associated with the syndrome, knee injuries such as PCL tears may be more likely.
