Sounds like your second opinion ortho is the "protect rom early guy" there are a lot of others on here that used the same same concept with no problems. My orhto was was like your 1st. he protected the injury with little flexion in the brace (30-40 6 weeks) and every week i increased the brace 10 degrees. I was allowed full weight bearing right after surgery. I didnt start PT until 12 weeks. Im at 14 weeks with 100 rom and weight training. walking 2-3 miles a day and a lot of swimming.
one of my favorite stretches is lie down on your stomach with a strap around your ankle, pull your leg towards your head getting a real good quad stretch. works for me..
That was one of my favorite stretches too. I was able to increase ROM significantly with that stretch.
