Introduction: Fractures of the patella are serious injuries commonly caused by direct trauma of the anterior knee surface. Various techniques such as tension band wiring (TBW) and cerclage wiring have been proposed.
Case: A 55-year-old woman who had a neglected left patellar fracture for 8 years. Radiographic evaluation revealed complete fracture of the left patellar bone with displacement and visible callus, fusion of the superior patellar fragment with the epi-metaphysis of the right femur with soft tissue swelling, malunion impression, left patellar subluxation anteriorly and grade III osteoarthritis. An open reduction internal fixation using tension band wire and cerclage was performed and postoperative evaluation revealed acceptable alignment of the patella and implant. Total Bostman knee was 28 points to analysis knee function.
Discussion: TBW is one of treatment methods for patella fracture fixation by counteracting muscle traction, maintaining the reduction and transforming the tensile forces between the quadriceps muscle and the anterior tibia tuberosity to
compress the patella articular cortex during knee flexion. It also stabilizes the fracture and enhances bone healing by closing the fracture gap and maintaining the interfragmentary contact. Cerclage wire is passed through the quadriceps and patellar tendon. Knee immobilization is unnecessary and the functional outcome is always adequate.
Conclusion: TBW with cerclage is favorable to stabilize a neglected transverse patella fracture. It is associated with satisfying clinical outcome and less complications. The placing of the tension band close to the patella decreases the
rate of major loss of reduction and implant failure.
