ACL Reconstruction Surgeon in Hinsdale
ACL injuries occur mostly during sports activities. The injured or torn ACL can be reconstructed by replacing the damaged portion with a part of the patellar tendon taken from the leg. Dr. Riff provides diagnosis and minimally-invasive ACL reconstruction using patellar tendon in Hinsdale. Dr. Riff also provides the highest level of care during and after the surgery.

What is ACL Reconstruction with Patellar Tendon?
Anterior cruciate ligament (ACL) reconstruction with patellar tendon is a surgical procedure that replaces the injured ACL with a patellar tendon. The goal of ACL reconstruction surgery is to tighten your knee and to restore its stability.
The anterior cruciate ligament is one of the four major ligaments of the knee that connects the femur (thighbone) to the tibia (shinbone) and helps stabilize the knee joint. The anterior cruciate ligament prevents excessive forward movement of the lower leg bone (tibia) in relation to the thighbone (femur) as well as limits rotational movements of the knee.
A tear of this ligament can make you feel as though your knees will not allow you to move or even hold you up. Anterior cruciate ligament reconstruction is surgery to reconstruct the torn ligament of your knee with a tissue graft.
Causes of an ACL Injury
An ACL injury most commonly occurs during sports activities that involve twisting or overextending your knee. An ACL can be injured in several ways:
- Sudden directional change
- Slowing down while running
- Landing from a jump incorrectly
- Direct blow to the side of your knee, such as during a football tackle
Symptoms of an ACL Injury
When you injure your ACL, you might hear a loud "pop" sound and may feel the knee buckle. Within a few hours after an ACL injury, your knee may swell due to bleeding within the torn ligament. You may notice that the knee feels unstable or seems to give way, especially when trying to change direction.
Diagnosis of an ACL Injury
An ACL injury can be diagnosed with a thorough physical examination of the knee and diagnostic tests such as X-rays (to rule out fractures), MRI scans and arthroscopy. In addition, your surgeon will often perform the Lachman’s test to see if the ACL is intact. During a Lachman test, the knee with a torn ACL may show increased forward movement of the tibia and a soft or mushy endpoint compared to a healthy knee.
The pivot shift test is another test to assess ACL tears. During this test, if the ACL is torn, the tibia will move forward when the knee is completely straight and as the knee bends past 30° the tibia shifts back into correct place in relation to the femur.
Procedure for ACL Reconstruction with Patellar Tendon
Anterior cruciate ligament reconstruction patellar tendon is a surgical procedure to replace the torn ACL with part of the patellar tendon taken from your leg. The new ACL is harvested from the patellar tendon that connects the bottom of the kneecap (patella) to the top of the shinbone (tibia). The procedure is performed under general anesthesia.
Your surgeon will make two small cuts about ¼ inch around your knee. An arthroscope, a tube with a small video camera on the end is inserted through one incision to see the inside of the knee joint. Along with the arthroscope, a sterile solution is pumped into the knee to expand it, providing your surgeon with a clear view of the inside of the joint.
The torn ACL will be removed and the pathway for the new ACL is prepared. Your surgeon makes an incision over the patellar tendon and removes the middle third of the patellar tendon, along with small plugs of bone where it is attached on each end. The remaining portions of the patellar tendon on either side of the graft are sutured back after its removal. Then the incision is closed.
The arthroscope is reinserted into the knee joint through one of the small incisions. Small holes are drilled into the upper and lower leg bones (tibia and femur) where these bones come together at the knee joint. The holes form tunnels in your bone to accept the new graft. The graft is then pulled through these holes. The new tendon is then fixed into the bone with screws to hold it in place while the ligament heals into the bone.
The incisions are then closed with sutures and a dressing is placed.
Postoperative Care following ACL Reconstruction with Patellar Tendon
Following the surgery, rehabilitation begins immediately. A physical therapist will teach you specific exercises to strengthen your leg and restore knee movement. Avoid competitive sports for 5 to 6 months to allow the new graft to get incorporated into the knee joint.
Anterior cruciate ligament reconstruction is a very common and successful procedure. It is usually indicated in patients who desire to return to an active lifestyle, especially into sports that involve running and twisting. Anterior cruciate ligament injury is a common knee ligament injury. If you have injured your anterior cruciate ligament, surgery may be needed to regain full function of your knee.
Risks and Complications of ACL Reconstruction with Patellar Tendon
The possible risks and complications associated with ACL reconstruction with the patellar tendon method include:
- Blood clots (deep vein thrombosis)
- Nerve and blood vessel damage
- Failure of the graft
- Loosening of the graft
- Decreased range of motion
- Crepitus (crackling or grating feeling of the kneecap)
- Pain in the knee
- Recurrence of injury to the graft
