Recovery from ankle replacement surgery can take between three and six months, states MedlinePlus. Assistance with daily tasks is required for up to six weeks, and recovering patients must keep weight off the affected foot for 10 to 12 weeks.
Ankle replacement surgery involves the removal and reshaping of damaged bones and the installation of an artificial ankle joint. Swelling around the new joint is normal, and the whole ankle area may feel warm and tender for four to six weeks, states MedlinePlus. Rest and elevation of the leg is key in the first stage of recovery, and it may be a full six months before the patient can resume normal activity levels.
