My wifes follow up meeting at mbst stamford Lincs showed a 50% improvement in knee joint flexing distance. Pain has gone - particularly in bed and walking. She no longer complains about her knee at all. I would consider the experience has been a positive one & beneficial - especially when you consider what is involved with the alternative of knee surgery, pain, limitations of use & longevity of the actual new knee as a part. Meetin s-in- law next weekend - will be interested in his experience comments
