A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
Yeah but while PGE2 promotes cartilage repair, it also plays roles in inflammation, fever, and gastrointestinal issues. If PGE2 levels rise too high or in the wrong context, it could cause unwanted inflammation or side effects similar to NSAIDs (e.g. stomach irritation).
I think I’d be okay with some stomach irritation to regain use of my knees in my old age.
