Abstract

A 33-year-old male sustained Hoffa fracture of the lateral femoral condyle 10 months after arthroscopic reconstruction of the anterior cruciate ligament in the same knee. The ligament had been reconstructed with autologous, quadrupled hamstring graft and was anchored in the femoral tunnel with a cortical suspensory device. As the fracture line did not involve the femoral tunnel, the ACL graft was spared, and the fracture was managed by open reduction and internal fixation. Fracture union was achieved by 6 months and the patient recovered uneventfully. At the 5- year follow-up, the patient had a stable pain-free knee. This case report highlights the possibility of late lateral femoral condyle Hoffa fracture treatment via arthroscopic ACL reconstruction without extra-articular tenodesis and despite taking adequate intra-operative precautions during tunnel drilling and using a cortical suspensory device for anchoring the graft on the femoral side.

前交叉韧带重建膝关节股骨外侧髁晚期Hoffa骨折
一例33岁男性患者在同侧膝关节经关节镜重建前交叉韧带10个月后发生股骨外侧髁Hoffa骨折。该韧带采用自体四肢腘绳肌腱移植物重建,并用皮质悬吊装置固定在股骨隧道中。由于骨折线未累及股骨隧道,因此保留了ACL移植物,并通过切开复位和内固定治疗骨折。6个月骨折愈合,患者顺利康复。在5年的随访中,患者的膝关节稳定无痛。本病例报告强调了通过关节镜下前交叉韧带重建治疗晚期股骨外侧髁Hoffa骨折的可能性,无需关节外肌腱固定术,尽管在隧道钻孔过程中采取了充分的术中预防措施,并使用皮质悬置装置将移植物锚定在股侧。
