All operations carry a small risk of complications but fortunately they are uncommon after ankle arthroscopy (less than 2 in 100 cases) and they are usually minor. You will have an anaesthetic which, even using modern techniques, still carries a slight risk and varies depending on your general health. Possible complications of an arthroscopy include:
- Sensitive or numb scar.
- Bleeding into the joint.
- Blood clot or venous thrombosis.
- Nerve or blood vessel injury.
- Damage to the joint.
- Excess and prolonged pain (chronic regional pain syndrome – CRPS).
The most common after effect (though still unusual) is a patch of numb skin or sensitive scar due to damage to the small nerves in the skin. This normally settles gradually but it can take several months.
Infections usually only involve the wound area but can spread to involve the joint. Most infections settle after a short course of antibiotics, but very rarely they require a further arthroscopy to wash out the joint.
Blood clots in the veins or lungs are also very unusual. Certain types of oral contraceptive (the pill) may increase this risk and may need to be stopped six weeks before your surgery. If you are on the pill, you must inform your surgeon and discuss your options before booking any surgery.
