Everyone recovers differently from injuries and illnesses. I completely severed both my patellar tendons in a degloving injury (every except the bones came off the legs from the knees down to the feet and they wanted to amputate them). I ended up living in/out of the hospital and Hyperbaric Chamber for a year. The Chamber is what saved me and grew the fibers back (or most of them). I never had surgery on the tendons; only extensive graft surgery. Yes, I'm much weaker than I used to be and I had to make life changes, but at least they didn't have to amputate them. I struggle to walk every day, but I'm determined and won't give up. I have pain over the tendons and do my home PT since I was never sent to PT because my other injuries were so severe. So don't give up. These things take time to heal. And realize that you may have to make some lifestyle changes to accommodate living with this.
I'm sorry to hear about your injury. I ruptured my tendon playing rugby around the same time as you. I'm 9 weeks post op now. I'm curious about your progress. I can bike and walk (with slight limp). I've got passive range of motion to 95-100 degrees (15-20 more degrees when I push it). I can single leg press ~100lbs for sets of 10 reps. Still have frequent pain, mostly where the shin anchors are located. Pretty constant heat and swelling in the joint.
Are you experiencing similar symptoms/issues with swelling and ROM?
