Hi @deb_iatonna and welcome. Here's a couple of medical journals regarding Arthroplasty (knee replacement) :- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5045468/ https://www.whhs.com/News/2015/April/Total-Knee-Replacement-Restores-Womans-Mobility.aspx They're both a few years ago, so I dare say the medical profession have moved on, having learned from these reports.

Depending on the pathology you may have a partial knee replacement or a full knee replacement. If you are in the UK it is worth considering Mr Chris Dodd at the Nuffield Orthopaedic Centre in Oxford. He is a well known and respected pioneer in the field of knees. He and his team have developed the 'Oxford Knee' which is a partial knee replacement. I know someone who took part in the trial where they were MRI'd and then instead of a choice of 4 sizes the implant was produced as a custom-item. Either way, the orthopods in the 1st world have great experience with knees and there is much quality information available. In the US the knee expertise is often clustered around the large ski resorts. Many experts practise there. One of the key things is patient engagement in all the recovery physio. It is a big thing and requires a lot of effort from the patient to give good results. Best of luck. Dominic
