I have some wrap arounds made by Stomatex. Not sure if you can still buy that brand anymore. They work well for me when I have soreness.
Also have a sleeve type I wear on occasion when only one knee bothers me.
Lately knees have been better so neither type worn for a while. Usually need them in the spring, I don't really know why.
Started wearing knee pads for basketball and volleyball too. Looks pretty dorky but they really help protect knees from impact injuries.
