Early treatment is recommended, as delayed management may negatively impact functional outcomes. We present two cases evaluated one year after sustaining a traumatic quadriceps tendon rupture. Imaging studies confirmed the diagnosis and defined the extent of the injury. Open surgical repair was performed, with satisfactory clinical outcomes observed at one-year follow-up. Objective To describe the surgical technique used in the management of two cases of chronic complete quadriceps tendon rupture, employing different operative strategies, and to report their medium-term outcomes. knee extensor mechanism quadriceps tendon chronic rupture reconstruction allograft suture anchors Full Text Additional Declarations No competing interests reported.
