Hello jteresavd,
Welcome to the NeuroTalk Support Groups!
I just wanted to let you know that Henry only made a couple of posts back in 2013, so it is possible he may not see your reply.
I see you're looking for information regarding knee replacements and Peripheral Neuropathy. You may have already done it, but you could use the link below
Forum Search Feature
to find any other threads or posts.
I see you've asked on the Peripheral Neuropathy forum so that's good.
I hope you find some answers to your questions and all the best to you and your Mum.
