ACL (Anterior Cruciate Ligament) Surgery Basics

ACL Reconstruction


You are having an anterior cruciate ligament (ACL) reconstruction. Surgical repair seeks to correct mechanical instability of the knee joint.

One incision is made in the front of your knee from which tendons are harvested. These tendons are used to serve as the new ACL. Two tunnels are drilled in the bone and this new ACL is attached to both ends.

Your surgery will take approximately one to two hours. You will wake up in the recovery room where your progress will be observed for about an hour. Your family or friends may visit you here.


You should not have anything to eat or drink 8 hours prior to your surgery check in. All medications should be discussed before your surgery takes place. Most medications can be taken the day of surgery, following the procedure.

If you are diabetic, or have any other concerns about medications, please discuss this with the surgeon as special arrangements may be necessary. The anesthesiologist will try to speak with you the night before to discuss anesthesia.

Should this call be missed, you will speak to the anesthesiologist at the bedside before your procedure begins. Please wear loose clothing. Please have the correct date, time and location of your surgery confirmed before the date.

You will need someone to drive you home and accompany you for the next 24 hours.


You will have a brace in place that will secure and limit the activity of your leg until you are seen at your first post-operative visit the following week. Please use the brace as prescribed.

Your weight-bearing status will be determined by your surgeon. You will also have a cold pack that is attached to a cooling unit which you may use according to your tolerance.

Please be aware of the skin beneath the cooling pad and protect it with a thin cloth or towel to avoid burning or other skin irritation.

No bathing or soaking until the incisions are completely healed, usually 7-10 days.

Start your physical therapy as prescribed, often this will be within 3-5 days after surgery. You will have a scheduled post-operative visit in a week to 10 days following your procedure. At that time, the surgeon will meet with you and discuss your surgery findings, pertinent information, future prognosis and rehabilitation plan.

We will also give you recommendations regarding activity and limitations. Usually, we will check your progress once every month.

You are encouraged to call our office with any questions that you may have after the procedure. You should call immediately should you develop a temperature greater than 101 F, numbness, tingling or calf pain in the operative leg, excessive drainage or excessive bleeding from the incisions, nausea or vomiting, uncontrolled pain or any other symptoms that you have concerns about.

Patients older than 20 are asked to take 1 baby aspirin (81 mg) twice daily for 14 days following surgery to prevent blood clots. If you are allergic to aspirin or have a medical reason not to take aspirin, please let us know.
