Surgical arthroscopy of the ankle, specifically involving the tibiotalar and fibulotalar joints, is a minimally invasive procedure that allows for direct visualization and intervention within the ankle joint. This procedure is performed in conjunction with ankle arthrodesis, commonly known as ankle fusion, which is a surgical technique aimed at stabilizing the ankle joint by fusing the bones together. Ankle instability, which may arise from various conditions such as severe arthritis, trauma, or chronic ligamentous injuries, can lead to significant pain and functional impairment. The surgical approach begins with the careful positioning of the leg on an L-shaped bar, ensuring that the thigh is supported while allowing the lower leg to move freely. This positioning facilitates access to the ankle joint. The procedure involves the use of a saline solution to inflate the joint, which aids in the creation of a working space for the surgeon. Through the insertion of a trocar and an arthroscope, the surgeon can inspect the joint for any pathological changes, including injury, disease, or signs of infection. The subsequent steps involve the removal of damaged tissue and bone spurs, ultimately preparing the joint for fusion. This comprehensive approach not only addresses the immediate concerns of joint instability but also aims to restore function and alleviate pain for the patient.
