CASE: A 16-year-old woman presented with acute on chronic knee pain and instability following a twisting injury. The tibial insertion of the anterior cruciate ligament (ACL) was nonvisualized on magnetic resonance imaging. A cord-like ACL, originating from the lateral intercondylar notch and inserting smoothly into the anterior horn of the intact lateral meniscus, was found on arthroscopy. Her ACL was reconstructed with quadriceps tendon autograft. CONCLUSION: We report a rare case of dysplastic ACL inserting into the lateral meniscus in a patient without obvious skeletal deformities. This pathology could be congenital or traumatic. Surgeons and radiologists should be aware of this rare variant.
