My shiny new Donjoy Lateral Unloader Brace:

The purpose is to push the knee slightly outward, unloading the weight from the outside of the knee where stuff is damaged, carrying weight on the inside of the knee where things are in excellent chape. I’m supposed to wear it during strenuous weight-bearing activity (thankfully not needed for cycling). “Strenuous” currently includes pulling weeds, which I did this morning in the backyard for the first time in a month and a half. Or sweeping the bedroom.
