I read an interesting article by an OS and while I don’t agree with all his thoughts I did find the ones on stretching interesting.
He said in the first 4 to 6 weeks when we do heel slides and ankle on roll to extend knee, he would rather see people do one stretch and hold it for a minute or longer than multiples held for 5 seconds. His reasoning is that all the bending of the knee that early increases swelling and inflammation. His premise is to focus on the two end points of extension and flexion by one long stretch and not aggravate the knee. He felt the in between movements happen with normal activity.
I thought it was interesting not sure what others think but gives me thoughts for the next knee.
