17 Weeks post op - Bilateral tears. I have been given a new exercise this AM by the PT. Treadmill inclined and walking backwards! Really targets the Extensor Lag issue. Make sure you have a spotter to adjust the speed/incline as you are facing away from the control panel.
Skicarver that was one of my regular exercises when I had this same injury several years ago. I had a great recovery from that QTR and I can only think it was because my PT was so good. Good luck with it!
