What is ankle arthroscopy?

Ankle arthroscopy is a minimally invasive surgical procedure that orthopaedic surgeons use to treat problems in the ankle joint. Ankle arthroscopy uses a thin fiber-optic camera (arthroscope) that can magnify and transmit images of the ankle to a video screen.

What are the goals of ankle arthroscopy?

The goals of surgery are to reduce ankle pain and improve overall function.

 

What is arthroscopy used for?

Arthroscopy can be used to diagnose and treat different disorders of the ankle joint.

The list of problems that can be treated with this technology is constantly evolving and includes:

 

Ankle arthritis: Ankle fusion is a treatment option appropriate for many patients with end-stage ankle arthritis. Ankle arthroscopy offers a minimally invasive way to perform ankle fusion. Results can be equal to or better than open techniques.

 

Ankle fractures: Ankle arthroscopy may be used along with open techniques of fracture repair. This can help to ensure normal alignment of bone and cartilage. It may also be used during ankle fracture repair to look for cartilage injuries inside the ankle.

 

Ankle instability: Ligaments of the ankle can become stretched out, which can lead to a feeling that the ankle gives way. These ligaments can be tightened with surgery. Arthroscopic techniques may be an option for this problem.

 

Anterior ankle impingement (also referred to as athletes ankle or footballers ankle):

 

Ankle impingement occurs when bone or soft tissue at the front of the ankle joint becomes inflamed. Symptoms include ankle pain and swelling. This can limit the limit to bend the ankle up. Walking uphill is often painful. Osteophytes (bone spurs) can be seen on X-ray. Arthroscopy can be used to shave away inflamed tissues and bone spurs.
