INTRODUCTION: Bilateral patellar tendon rupture is an uncommon injury, particularly in young, healthy individuals without established risk factors for tendinopathy. Most reported cases involve systemic disease or medication-related tendon compromise. We present a rare case of simultaneous bilateral patellar tendon rupture in a healthy, athletic male following an indirect mechanism of injury.
CASE PRESENTATION: A 33-year-old man sustained acute bilateral knee injuries while playing recreational rugby. He reported an audible "pop" in both knees, immediate pain, and inability to extend either leg. He had no history of diabetes, connective tissue disease, corticosteroid or fluoroquinolone use, nor other recognized risk factors. Clinical assessment demonstrated inability to straight leg raise bilaterally, with a palpable tendon defect only on the right side. Point-of-care ultrasound suggested bilateral tendon rupture, though diagnostic uncertainty persisted for the left knee due to swelling. The patient underwent urgent surgical repair of the right tendon using a Krackow suture technique with transosseous fixation, followed by delayed repair of the left tendon after departmental ultrasound confirmed rupture. Intra-operatively, both tendons appeared macroscopically degenerative. Postoperative rehabilitation involved bracing, progressive range of motion, and physiotherapy. At 3-month follow-up, he had regained full functional range of motion and returned to unrestricted daily activity.
DISCUSSION: Bilateral patellar tendon rupture in the absence of systemic risk factors is rare and may be underrecognized, especially when clinical signs are obscured. This case highlights the diagnostic value of point-of-care ultrasound in ambiguous presentations and reinforces the importance of early surgical repair and structured rehabilitation for optimal functional recovery.
