Why is it done?
For severe pain in the ankle usually secondary to
osteo-arthritis or rheumatoid arthritis.
An x-ray of the ankle confirms the degree of
degenerative arthritis within the ankle.
Very occasionally an additional CT scan of the ankle may be required for
additional pre-operative information.
Surgery is performed as an inpatient (5-7 days)
under general anaesthesia or under spinal anaesthesia. An incision is
made down the front of the ankle, the ankle joint is then removed and
replaced with a metal and plastic joint. After surgery the skin is
sutured and a bulky dressing is applied. Patients are then placed
into a post operative plaster or boot. Patients are allowed to weight
bear as tolerated after surgery with the protection of crutches.
