What to expect from joint fusion surgery for ankle osteoarthritis

The surgeon removes the worn joint surfaces and holds the ankle bones together with fixation so they can heal as one stable unit. The operation aims to reduce pain from movement, but it also limits motion at the fused joint. Walking mechanics may feel different, and nearby joints can take on more movement. Your surgeon considers the arthritis pattern, bone quality, activity needs, and other health factors before recommending this approach.

Arrange help with meals, washing, transport, and stairs because the ankle may need a cast or boot and limited weight-bearing at first. Prepare a safe route at home and use the walking aid taught by your team. Keep the dressing or cast dry, elevate the leg as advised, and attend imaging or wound checks. Progress to weight-bearing and exercises only when your surgeon confirms that healing is ready.

Contact the surgical team for increasing wound redness, drainage, swelling, pain that is not controlled, or a cast that feels too tight. Seek urgent help for new calf swelling or pain, chest pain, sudden breathlessness, a cold or pale foot, or loss of sensation. These symptoms can indicate complications requiring immediate assessment.

Ask which ankle joint will be fused, how long protection is expected, what equipment you will need, and how progress will be checked. Discuss footwear, driving, work, physiotherapy, and what happens if bone healing is slower than planned.
