Bilateral Traumatic Rupture of the Quadriceps Tendon - A Case Report

Introduction: Quadriceps tendon rupture is a traumatic injury where the quadriceps detaches from the patella, disrupting the knee's extensor mechanism. Bilateral ruptures, first documented in 1949, are rare, with an incidence of 0.17-2.5% Diagnosis involves a clinical examination, revealing a palpable defect above the patella and inability to perform a straight leg raise. Risk factors include metabolic disorders, rheumatoid arthritis, connective tissue diseases, and steroid use. In younger patients, it often results from direct trauma. Magnetic resonance imaging is the preferred diagnostic tool. While partial tears may be managed non-operatively, surgical repair is typically required for complete disruption of the extensor mechanism.

Case report: A young man presented with an inability to walk for 1 month after a fall. He was diagnosed with bilateral quadriceps tendon rupture. Primary open repair was performed, followed by the application of bilateral long knee braces. The patient was advised delayed weight-bearing and initiated on quadriceps strengthening exercises.

Conclusion: After 12 months of follow-up, the patient showed significant improvement in function and range of motion compared to preoperative status. Primary open repair of bilateral quadriceps tendon ruptures proved to be an effective treatment, leading to satisfactory recovery and a return to good functional outcomes.
