Bilateral Simultaneous Quadriceps Tendon Rupture in a 92-Year-Old independently mobile patient: A Case Report and Review of the Literature.

Introduction: Simultaneous bilateral quadriceps tendon ruptures are uncommon knee injuries, though reported to frequently occur in males over 50 years of age. Bilateral simultaneous ruptures are rarely associated with minor trauma (1), but often associated with certain predisposing factors like obesity, diffuse idiopathic skeletal hyperostosis, steroids use, use of anabolic steroids, chronic tendonitis, chronic renal failure, rheumatoid arthritis, systemic lupus, gout and hyperthyroidism (2)(3). Objective: The objective of our presentation is to present a rare case of simultaneous bilateral quadriceps tendon rupture in an independently mobile elderly patient with well controlled mild hypertension and heart murmur (not on any medications for heart murmur), and the absent of known predisposing factors. Case Report: A 92 year old, otherwise fit and healthy gentleman, apart from well controlled hypertension and heart murmur (not on any medications for heart murmur), presented at the emergency department with bilateral suprapatellar knee pain and swelling after a trivial trauma. The patient missed a step at home while descending stair and leaned onto the wall to steady himself. The day after his presentation, 24 hours following the injury, the patient underwent a successful surgery for the repair of bilateral quadriceps tendon rupture. Following the repair, both legs were immobilised in plaster cylinder casts. Conclusion: Minor trauma resulted in the simultaneous bilateral quadriceps tendon ruptures in an active elderly male with no commonly associated risk factors.
