Anyone had any luck with getting a lube job for their knee?

I've been gobbling 5 grams MSM / day for 15 years, and have more or less kept the boogeyman away, until recently. Sitting here with a knee brace on my left, recalling a conversation with a specialist recently. Kaiser will not prescribe the injection until after a single cortisone shot. Not happy about cortisone, but if that is the qualifier to get me into the race, then so be it.

I would like to find out what you experienced when you had the lube job on your knee?
