A Minimally Invasive Open Approach With Ultrasound Guidance for Tibial Avulsion Fracture of the Posterior Cruciate Ligament: The Surgical Technique

Surgical intervention is generally recommended for a displaced tibial avulsion of the posterior cruciate ligament. However, there is still controversy regarding the optimal operative procedure, particularly between the conventional open approach and arthroscopic techniques. We have developed a new, minimally invasive open approach with ultrasound guidance that allows for precise localization of neurovascular structures, reducing the risk of injury while maintaining clear access to the fracture site. We report the surgical technique and describe a case series of patients who were treated with this new method. This method is simpler and requires less technical expertise than the conventional open approach or arthroscopic techniques, thereby having the potential to be a safe and practical alternative for treating the tibial avulsion of the posterior cruciate ligament.
