What is ankle arthroscopy?

Ankle arthroscopy is minimally invasive surgery that diagnoses or treats many ankle problems. Common problems include infections, injuries, arthritis, inflammatory conditions, and unexplained ankle symptoms. Ankle arthroscopy uses an arthroscope with a tiny camera to view the inside of the ankle joint. Special instruments allow your doctor to treat joint problems through small incisions. Ankle arthroscopy can relieve symptom and restore range of motion.

Ankle arthroscopy is a common surgery, but it involves some risk and potential complications. You may have less invasive treatment options. Consider getting a second opinion about all of your treatment choices before having ankle arthroscopy. 

Other surgical procedures that may be performed

Your doctor may also perform a biopsy. A biopsy involves removing a cell or tissue sample and testing it for cancer and other diseases. 

You may need open surgery (ankle arthrotomy) for an ankle condition that your doctor cannot treat with arthroscopy. Open surgery involves making a longer incision that allows your doctor to directly view and treat the ankle.

Why is ankle arthroscopy performed? 

Your doctor may recommend ankle arthroscopy to diagnose ankle symptoms when a cause is not clear. Ankle arthroscopy can also treat ankle conditions when symptoms have not responded to other treatments. Ankle arthroscopy is not the first choice to treat ankle conditions. Ask your doctor about all of your treatment options and consider getting a second opinion.

Your doctor may recommend ankle arthroscopy to diagnose or treat: 

  • Ankle joint infections, also called septic arthritis
  • Ankle joint injuries, including fractures, torn ligaments, torn cartilage, and overuse injuries
  • Inflammatory forms of arthritis, including rheumatoid arthritis
  • Loose bodies, including bone fragments and cartilage pieces
  • Osteoarthritis, or degenerative joint disease, which is the breakdown of cartilage and bones
  • Synovitis, or inflammation of the lining of the joint
  • Unexplained ankle symptoms, including pain, swelling, locking, catching and grinding

Who performs ankle arthroscopy?

Orthopedic surgeons and foot and ankle surgeons perform ankle arthroscopy. Orthopedic surgeons are specially trained to treat problems of the bones and joints. They perform surgery and prescribe other treatments. Foot and ankle surgeons are orthopedic surgeons or podiatrists who further specialize in surgery of the foot, ankle, and lower leg.

How is ankle arthroscopy performed?

Your ankle arthroscopy will be performed in a hospital or outpatient surgery setting. It is a minimally invasive surgery that involves making at least two small incisions in the ankle. Your surgeon will insert an arthroscope and special instruments through the incisions. A tiny camera on the arthroscope allows your surgeon to view the inside of your ankle on a video screen. Your surgeon will examine and repair joint damage as needed. 

Types of anesthesia 

Your surgeon will perform your ankle arthroscopy using either general anesthesia or regional anesthesia. 

  • General anesthesia is a combination of intravenous (IV) medications and gases that put you in a deep sleep. You are unaware of the surgery and do not feel any pain. 
  • Regional anesthesia is also known as a nerve block. It involves injecting an anesthetic around certain nerves to numb a large area of the body. You will likely have sedation with regional anesthesia to keep you relaxed and comfortable. 

What to expect the day of your ankle arthroscopy

The day of your surgery, you can expect to:

  • Talk with a preoperative nurse. The nurse will perform an exam and ensure that all needed tests are in order. The nurse can also answer questions and will make sure you understand and sign the surgical consent form.
  • Remove all clothing and jewelry and dress in a hospital gown. It is a good idea to leave all jewelry and valuables at home or with a family member. The surgical team will give you blankets for modesty and warmth.
  • Talk with the anesthesiologist or nurse anesthetist about your medical history and the type of anesthesia you will have.
  • A surgical team member will start an IV.
  • The anesthesiologist or nurse anesthetist will start your anesthesia.
  • A tube may be placed in your windpipe to protect and control breathing during general anesthesia. You will not feel or remember this or the surgery as they happen.
  • The surgical team will monitor your vital signs and other critical body functions. This occurs throughout the surgery and during your recovery until you are alert, breathing effectively, and your vital signs are stable.
