3 knee surgeries. One bad ACL, no cartiledge left anywhere. Arthritis all over the place.
I've got 1" thick rubber mats in front of all my major power tools. Picked em up cheap at Costco several years ago. They've got a honeycomb pattern which makes cleanup a pain, but that's what shopvacs are for.
I've got some crocs, but I don't like the way they fill up with shavings at the lathe. I tend to wear my New Balance 991s. Runners call these the knee shoe. My orthopedic surgeon recommended them.
Remember to have a good balanced stance and move around regularly.
Don't you just love it when you have to do a deep knee bend to get one of your kneecaps back in the right place?
Gary, who's really trying to avoid any knee replacements.
Where did I put that tape measure...
