When is prehabilitation recommended for ACL tear?

After an ACL injury, the knee may be swollen, stiff, weak, or difficult to control. Prehabilitation is supervised preparation rather than a test of toughness. It can include safe range-of-motion work, quadriceps and hip strengthening, balance practice, walking guidance, and education about crutches or a brace when these are prescribed. The exact plan depends on knee stability, associated injuries, sport or work demands, and the treatment route chosen with your clinician.

Arrange review after the injury so the knee can be examined and the exercise plan tailored. Work toward comfortable movement and controlled weight bearing rather than rushing back to pivoting, jumping, or contact activity. Use ice, elevation, or medication only as advised for you. Tell the therapist if the knee locks, gives way, becomes more swollen after exercise, or cannot fully straighten; those details can change the plan.

Seek prompt assessment for a deformed knee, inability to bear weight, a hot red joint with fever, a locked knee, severe calf swelling, or new foot numbness or colour change. These findings need examination because an ACL tear can occur with other knee or circulation problems.

Ask whether other structures are injured, what knee movement should be regained first, whether a brace or crutches are needed, and how prehabilitation fits with surgery or non-surgical care.
