PSA: a 2019 study found 1 in 3 finishers get bad knees before 45, and my doctor just confirmed it
Saw that number in a trade mag at the supply yard and laughed it off until my ortho in Dayton told me my right knee is already showing wear at 41. He said it's the years of kneeling on hard trowel work, not the lifting. Any of you switched to knee pads or a rolling knee board and actually noticed a difference?
