What causes a cyclops lesion in the knee?
Etiological Factors. Cyclops lesion is a nodule or hypertrophied graft tissue and is commonly associated with a more anteriorly placed tibial tunnel or a disorganized mass of scar tissue in the anterior compartment. It is the second most common cause of restricted knee extension after graft impingement.
How do you get rid of Cyclops lesions?
Symptomatic cyclops lesions, also referred as cyclops syndrome [8, 18], are treated by arthroscopic removal with eventually an additional notchplasty, regaining the full extension of the knee [19–22].
How do you know if you have a cyclops lesion?
The hallmark sign of a cyclops lesion is loss of knee extension range often about 2-3 months following an ACL surgery. However it can be an issue for years post-op. It is not a huge loss of extension, often less than 10°, but it’s enough to be a problem (8).
What is a cyclops lesion ACL?
Cyclops lesion or localized anterior arthrofibrosis, an arthroscopically treatable complication of anterior cruciate ligament (ACL) reconstruction, is a fibrous nodule located in the intercondylar notch anterior to the ACL graft. [1] The lesion has a typical MRI and arthroscopic appearance.
Is a cyclops lesion painful?
The cyclops lesion, also known as localized anterior arthrofibrosis, is a painful anterior knee mass that arises as a complication of anterior cruciate ligament (ACL) reconstruction, although has rarely been reported in patients with ACL injuries that have not been reconstructed.
Why is my knee popping after ACL surgery?
Knee clicking and popping are extremely common during the first year after any knee surgery. These are usually due to soft tissue swelling or early scar formation. Soft tissue massage is the trick to resolving the naturally healing tissue’s excess thickness.
How do you get rid of scar tissue from ACL surgery?
Mild cases of arthrofibrosis may be resolved with intensive physical therapy alone. Other treatments include manipulation under anesthesia, when a physician manipulates the knee in a controlled fashion to break up the scar tissue. Surgery may also be an option for some patients.
Is ACL a major surgery?
ACL surgery is a major surgery that reconstructs or replaces a torn anterior cruciate ligament (ACL) in your knee. Your doctor may only consider ACL surgery for you if it suits your needs and lifestyle.
How many years does an ACL repair last?
Rebuilt to last Not only is the procedure effective, but repaired tendons perform like new. Reconstruction patients even 20 years later revealed excellent performance, with over 85% still active.
What is a cyclops lesion in the knee?
What is a Cyclops Lesion? For those not familiar, a cyclops lesion is a wad of scar tissue in the anterior aspect of the knee joint. It is believed to be a remnant of the previous ACL stump that had remained during the reconstruction surgery. At least that’s one theory.
Are there any cases of Cyclops syndrome after ACL reconstruction?
Although the original description of cyclops syndrome was in patients who had undergone ACL reconstruction, more recent reports have documented its occurrence after ACL injury in the absence of ACL reconstruction. In this article, we review cyclops lesions in 10 proved cases in which the lesions occurred in the absence of reconstruction.
What causes loss of knee extension after Reconstruction?
All had a lesion in the intercondylar notch near the tibial insertion of the anterior cruciate ligament that acted as a mechanical obstruction to full knee extension. Grossly and histologically, these were similar to the cyclops lesion that also has been shown to cause loss of knee extension after anterior cruciate ligament reconstruction.
When to use the term Cyclops syndrome?
The term cyclops syndrome is used in patients with a post ACL reconstruction decrease in knee extension 4.
