Atraumatic Bilateral Patellar Tendon Rupture: A Case Report.

Abstract

Introduction: Bilateral patellar tendon rupture is an uncommon reason for extensor mechanism dysfunction. Various predisposing factors, including systemic diseases and the use of steroids or antibiotics, can elevate the risk. The patient typically presents with an inability to extend the knee, generalized pain and swelling, and a high-riding patella observed on lateral radiographs.

Case report: We report a case involving a 44-year-old man with no underlying risk factors or systemic disease who sustained a bilateral patellar tendon rupture following minor trauma. The patient was treated with bilateral primary transosseous end-to-end tendon repair, followed by a brief period of immobilization and an intensive rehabilitation program. Six months post-surgery, he could walk unassisted without pain, regain full range of motion in both knees, and carry out daily activities without limitations.

Conclusion: Timely diagnosis and immediate surgical intervention are crucial to preventing complications related to extensor mechanism failure and ensuring favorable functional outcomes.
