I have had right leg ankle surgery several years ago and now wear a brace. I also have had a right knee replacement and later a right knee revision. My walking has deteriorated to the extent that I walk with a cane and my balance is terrible. I am 73 years old and hope to at least go for walks again with my husband. Should I be looking for more orthopedic information or concentrate on my balance. My husband feels that I need a comprehensive balance assessment. Has anyone experienced problems such as those I have described. Thank you.
