What to Expect From ACL Reconstruction for an ACL Tear

ACL reconstruction uses a graft to replace the torn anterior cruciate ligament and help control forward and twisting movement of the knee. The surgeon may also assess or treat related meniscus or cartilage injuries. Early symptoms can include pain, swelling, limited bending and difficulty activating the thigh muscles. Recovery is measured by function and examination, not simply by how the knee feels on one day.

Use crutches, a brace, ice or prescribed medicine only as directed. Elevate the leg when resting and complete the exercises taught by your care team. Rehabilitation commonly progresses from reducing swelling and regaining knee straightening to improving bending, leg strength, balance, landing control and activity-specific movement. Do not return to cutting, pivoting or contact activity until your clinician has assessed readiness.

Seek prompt advice for increasing wound redness, drainage, fever, uncontrolled pain, new calf swelling or marked stiffness. Urgent care is needed for chest pain, severe breathlessness, fainting, or a foot that becomes cold, pale, numb or weak. A new giving-way episode, locking knee or sudden injury during recovery should also be reported.

Ask which graft and additional procedures are planned, how much weight you may place on the leg, when driving or work may be possible, and which tests will guide return to sport.
