  "abstract": "Introduction: Extensor mechanism injuries of the knee are uncommon and typically involve either the quadriceps tendon or the patellar tendon. Simultaneous contralateral rupture of the quadriceps tendon on the one side and the patellar tendon on the other is extremely rare. Systemic conditions such as chronic kidney disease (CKD), chronic liver disease, ochronosis, collagen disorders, and hepatitis C virus (HCV) are known to predispose to tendon weakness and rupture even after trivial trauma. Case Report: A 51-year-old male, a known case of CKD and HCV infection, presented in casualty with inability to walk following trivial trauma. Clinical examination revealed a suprapatellar gap with loss of active extension in the right knee and an infrapatellar gap with loss of active extension in the left knee. Radiographs showed features suggestive of quadriceps tendon rupture (patella baja) on the right side and patellar tendon rupture (patella alta) on the left side. The patient underwent open surgical repair of both tendons using non-absorbable Ethibond sutures with transosseous fixation. Postoperatively, the patient was immobilized, followed by gradual rehabilitation. At follow-up, satisfactory functional recovery with restoration of knee extension was achieved. Conclusion: Simultaneous contralateral quadriceps and patellar tendon rupture is a rare entity, particularly in patients with systemic comorbidities such as CKD and HCV. A high index of suspicion, thorough bilateral knee examination, and early surgical intervention are essential for favorable outcomes.",
