Ankle arthroscopy
This is designed to minimise the pain, swelling and stiffness in the arthritic ankle joint. Through two or three small holes, instruments are inserted into the ankle joint to wash debris from it and to remove loose pieces of bone, cartilage, inflamed tissue and bone spurs. You will need to rest and ice your ankle for 48 hours after surgery, and undertake a short post-operative physiotherapy programme. You will normally see 80% good or excellent results.
Ankle fusion
If a simple arthroscopy does not relieve the symptoms, then a more permanent solutions such as an arthroscopically assisted fusion may be required. Ankle fusion involves preparing both sides of the arthritic joint (left) back to healthy and bleeding bone (right). The arthritic joint lining is removed and the ankle joint is placed in a functional position and held there until the bone has grown across the joint and the ankle is thus fused.
The ankle is held in position whilst the fusion is occurring and this is most commonly done with large screws which are buried beneath the skin. Occasionally a large metal rod may need to be inserted through the heel to compress the ankle and sub-talar joints. This is known as a double fusion.
Ankle replacement
Ankle replacement involves replacing the two worn out surfaces with replacement highly polished surfaces and adding a high molecular weight polyethylene spacer between the two surfaces. Ankle replacement generally maintains the range of movement which a patient has pre-operatively. It is however not suitable for heavy manual or sporting activities.
