Why It's Done
- The ACL— one of two ligaments that crosses the middle of the knee — connects your thighbone to your shinbone and helps stabilize your knee joint. Most ACLinjuries happen during sports and fitness activities that can put stress on the knee: 1. Suddenly slowing down and changing direction (cutting) 2. Pivoting with your foot firmly planted 3. Landing from a jump incorrectly 4. …
Risks
- ACL reconstruction is a surgical procedure. And, as with any surgery, bleeding and infection at the surgical site are potential risks. Other risks associated with ACLreconstruction include: 1. Knee pain or stiffness 2. Poor healing of the graft 3. Graft failure after returning to sport
How You Prepare
- Before your surgery, you'll likely undergo several weeks of physical therapy. The goal before surgery is to reduce pain and swelling, restore your knee's full range of motion, and strengthen muscles. People who go into surgery with a stiff, swollen knee may not regain full range of motion after surgery ACLreconstruction is an outpatient procedure, so you'll be able to go home the sa…
What You Can Expect
- General anesthesia is typically used during ACL reconstruction, so you'll be unconscious during the procedure. ACLreconstruction is usually done through small incisions — one to hold a thin, tube-like video camera and others to allow surgical instruments access to the joint space.
