Instructables user Senseless has modified his wife’s knee brace to prevent lateral movement due to rheumatoid arthritis. He says it’s easier for her to get on than her normal brace, which aids in late-night bathroom trips. If you can endure the run-on sentences, he’s made an instructable detailing its construction. I’ve had knee problems since I was a kid, so if anybody’s got plans for a brace that prevents patellar subluxation, detail it in the comments!
