Under the flag of "to each his own"...I've worn these light pads for over 2.5 years now. At first I was so glad to be rid the cancer that the pads didn't factor in as much. Now it's a quality of life thing for me. Choosing a surgical alternative again is not for everyone, but I am ready to try something to stop the leaking. My doc says that 90% of the patients are dry the next day - I'm very hopefull. If I'm in the 10%, then it's a gamble I am willing to take. Leaking is not the end of the world; however, it does grate on some people more than others.
Speaking of knees, I run 2 miles each day before work and I leak less during that time than I may if I stretch the wrong way. Spreading your legs like getting into a vehicle is a prime opportunity to leak for me.
