Going up stairs uses your muscles to lift your body weight. Going down stairs puts compressive force directly through your knee joint as it controls your descent. When cartilage starts wearing down, that compression becomes painful in a way that climbing doesn't.
If you've noticed yourself favoring the railing on the way down, taking stairs one at a time, or avoiding them altogether, that's information worth paying attention to. It doesn't mean you need surgery. But it does mean something is changing in your joint.
Early evaluation gives you options. You can modify activities, strengthen supporting muscles, and take steps to slow progression. Waiting until the pain is constant limits what conservative treatment can do.
Your knees are talking. Listen to them!
