How I prepare my knees for 8 western mountain backpacking trips per year...at age 77

[Miles Killian]

I get hyaluronic acid every 6 months and cortisone (80mg Depo Medrol) in the intervening 3 months, so each every 6 months. I don't really think I feel a difference from either injection but then again I'm not bad enough that I limp. The hyaluronic acid is more to nourish the joint to help it last longer.
