Thanks for the information. I am an orthopedic surgeon and would be glad to give my opinion based on the information you have provided. If she is in good health and pain such that it interferes with activities of daily living and causes deterioration in quality of life she should go ahead with the surgery. There are risks associated with surgery but risks would be decreased if she does not suffer from any other chronic disease and the expected improvement in quality of life justifies the risk. Recuperation can take anywhere from 6 weeks to 12 weeks depending upon how enthusiastic the patient is post surgery.
