Hello @oceanspruce. This article might help provide a bit more information on the successes of MUA in relation to time from the original surgery, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9214639/.

It does state that "We found that ROM improved substantially after MUA. The gain in flexion decreased as the time between TKA and MUA increased." It is difficult to know the true outcome for each of us as we all heal so differently. I had my knee replaced in 2006 and had terrible issues with scar tissue formation. I underwent two MUAs with mixed results. I also attribute my poor recovery more to being young and not aggressive enough in my rehab. In 2006, I was told that manipulations were more successful in the first 12 months and after that there was some risk to bone fractures from the scar tissue becoming too strong for manipulation over time. This protocol may not apply to everyone and has possibly changed as 18 years in the medical field can be an eternity.

I'd like to invite @mpirruccel and @captjamesh to this discussion to share their experiences either with scar tissue and ROM issues or a MUA.

@oceanspruce - Were any other options discussed with you? I remember there being an option for surgical removal of the scar tissue, but ultimately I decided against the risk of infection and further surgery. Has this been discussed with you at all? Have the risks of an MUA this far out from your surgery been discussed as well?
