Don’t neglect the good tendon
That good tendon is going to do a lot of extra work for a long while. Make sure you don’t overdo it and make you sure you stretch and work it appropriately.
I spent a few days at Disney World a week after surgery. The first day we got a wheelchair. When it came to getting on and off the bus I would just hop. That was not a good idea. The next day my good achilles was super sore. Luckily it was just sore, it could have been worse.
I think ALL of us had nightmares about tearing the other AT while we depended it on it during our ATR recovery — and I don’t think any of us actually did that awful deed. Later, after returning to full-speed high-risks sports, is another matter, but not during the ATR rehab. That doesn’t mean it can’t happen, but it does mean it’s pretty rare.
I am experiencing soreness in the ‘good tendon’ as well and share the concern about ‘contra’ rupture particularly at this limited mobility stage. Hope Norm is right that it is rare during ATR rehab.
