Knee bulge

Recently developed a tender lateral patellar retinaculum (or something in that area, not totally sure, just referenced anatomy diagrams) that is visibly swollen during leg flexion. No real pain but it feels unstable or “loose” during normal walking, or standing up. Any reccomdation(s) to overcome? Thanks!
Left knee

Right knee for reference

Yeah, we aren’t really sure what this is man. If it bothers you, I’d recommend getting it checked out.
