hi wutti,
I am glad you share your experiences with us. Wearing knee brace doesn't mean full weight bearing. On contrary, it means maximum protection to the knee because full weight bearing is completly contraindicated in this phase. But wearing the brace and walking with crutches or walker is fine. So, as you see we both said that:
1-partial weight bearing.
2-PRICE(protection-rest-ice-compression-elevation)
3-every thing should be pain free.
4-find a good physiotherapy.
You are right about flexion to 60 not 90. But i am not agree with you about full extension . You shouldn't full extend the knee in the first week because that apply more stress on ACL.
I am waiting for your replies , we can discuss about this case together.
good luck.
