I’m bone on bone in my right knee from couple of meniscus tears and running a lot for 10+ years. As my knee pain and swelling was getting worse, I used an Ossur Unloader to get me thru the run of IMAZ in 2015 (I was 40yo at the time). I wore a Lycra sleeve underneath it, sprayed my leg with anti-perspirant, kept it very tight, and still had to stop every 8mi or so to re-tighten and adjust.

I saw the benefit as I don’t believe there was any way I could have ran a marathon without it. Definitely not the most comfortable thing to wear, but it was worth it.

That said, I’ve pretty much stopped running the past 3yrs as I just don’t want to do further damage to my knee as it’s more important that I can play with my kids than run at this point in my life.

Best of luck to you.
