Possibly: Zero degrees is your goal. Hyper extension is not friendly to the acl and involves some laxity of the ligament even without injury. Don't fret about the loss of hyperextension, as most who have it pre-op, lose it post-op if their surgery is successful to make a study sturdy ligament.

Hyper-extension-: -is not good for the ACL. The tears often are caused by hyper extension forces on the loaded leg. My have been part of the cause of your original injury.
