Hi All,
I totally agree with the above post suggesting surgery,especially if you are planning to continue your sorts career involving pivoting and twisting movements.
Relating to rehab part,there is a misconception regarding strengthening muscles.Some give emphasis on quadriceps.But biomechanically more role in knee stabilization and assisting work to ACL comes from Hamstring muscles and the recent research works also supports its importance in knee rehab after ACL surgery.
In later weight bearing phase,more emphasis is given to close kinetic exercises.here both quadriceps and hamstrings are contracting together to support the knee .tibial anterior translation and stress on the ACL graft is minimal during close kinematic partial squatting exercises.
