The purpose of this article is to report three cases of fracture of the middle third of lateral tibial condyle, the so-called Segond fracture.
Case 1. A 31-year-old male landed on his left foot with the knee adducted while playing volleyball. Initial examination revealed an instability to valgus stress at 30° of flexion. Radiographic examination of the left knee demonstrated avulsion of the lateral tibial condyle. The patient was treated with a cast.
Case 2. A 50-year-old male injured left knee in a traffic accident. Upon examination the left knee was remarkably swollen. Plain roentgenography of the left knee showed fracture of the lateral tibial condyle with transverse fracture of the proximal region of the tibia. The patient was treated surgically.
Case 3. A 21-year-old male landed on his left foot with the knee abducted with external rotation while playing volleyball. Initial examination revealed anterolateral rotatory instability with lateral meniscal sign. Roentgenography revealed a chip fracture of the lateral tibial condyle. Lateral partial meniscectomy was performed.
