Background:
Acute bilateral patellar tendon rupture is a rare occurrence, especially in young patients in the absence of comorbidities. We describe a case of bilateral patellar tendon re-rupture in a young patient without predisposing factors. Further, we explain a technique for autograft augmented patellar tendon repair with bidirectional fixation using an ipsilateral semitendinosus graft in transosseous patellar and tibia bone tunnels.
Case Presentation:
We present the case of a 40-year-old healthy worker with bilateral acute on chronic patellar tendon rupture maintained following initial trauma and Krackow repair 2 years ago. He underwent bilateral reconstruction using semitendinosus autograft. At 1 year postoperatively, he has maintained the full range of motion and strength without re-rupture.
Conclusion:
This is the first case describing a new fixation technique after bilateral patellar tendon re-rupture. The use of semitendinosus autograft for reconstruction of the patellar tendon after re-rupture is a viable and effective option.

Introduction to Documentation and Reporting
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...
