Knee injury heeled hyper extended is sports OK with brace?

My daughter who is 13 had a severe knee injury in September 2008 while playing soccer. She broke her tibia/patella in the growth plate. She had surgery the same day where they put 2 screws in her knee. She has been going through physical therapy for the past 5 months. They noticed her knee didn't look right when they started to run her. After going back to the doctor and having MRI done they ruled out any torn ACL/MCL, but of course was hard to see around the screws. They came to the conclusion that when her knee was heeling the growth plate started closing at the same time. Now her knee is hyper extended. They do not want to do surgery, because it is too extensive for a mild alteration they would have to cut the bone and insert plate. Dr. said months of recovery time. Has anyone dealt with this before? Will she be OK to wear a brace while playing sports?
