Arthroscopic excision of os trigonum impingement is a minimally invasive surgical procedure performed using an arthroscope, a small camera, and specialized instruments inserted through small incisions in the skin. The procedure involves removal of the os trigonum bone to relieve pain and improve mobility. It is typically performed as an outpatient procedure under local anesthesia with sedation or general anesthesia.

Following the procedure, the patient may experience some pain, swelling, and stiffness in the ankle joint. Rehabilitation is important to regain full range of motion and strength of the ankle. Physical therapy may be recommended to aid in recovery and prevent future injury. Full recovery may take several weeks to several months, depending on the individual case.

Arthroscopic excision of Os trigonum impingement is a minimally invasive surgical procedure performed to treat the pain and limited range of motion caused by an extra bone at the back of the ankle called the Os trigonum. This bone can cause impingement between the ankle and the back of the leg, leading to inflammation, pain, and stiffness. Arthroscopic excision of Os trigonum involves the removal of this extra bone using an arthroscope, which is a small camera attached to a tube inserted through a small incision in the ankle. The procedure is usually performed on an outpatient basis and can help relieve pain and improve ankle function. Rehabilitation after surgery typically involves a combination of rest, physical therapy, and gradual return to normal activities.
