Anterior Crucuiate Ligament Stability: Tests

At the Centeno-Schultz Clinic stability of a joint is critical.  It is one of the four cornerstone’s in our evaluation.







Laxity of the ACL of the knee is commonly associated with complaints of instability while walking on uneven surfaces and descending hills.

On physical examination there are two principal tests to determine ACL laxity.

Lachman Test:  with the knee flexed at 30 degreees the examiner pulls on the tibia to assess the amount of anterior motion of the tibia in comparison to the femur.

MRI, CT and x-rays of the knee do not identify laxity as this is a finding on dynamic testing of the joint.

Instability of the ACL predisposes to meniscus, cartilage and ligament injury , damage and pain.

There is an association between ACL integrity and osteoarthritis.

Keegan that looked at MRI’s on about 300 patient with known knee arthritis and found that 1 in 6 had ACL ligament abnormalities.

Stein in another study demonstrated that about 14% of knee OA patients had ACL abnormalities on MRI.

Treatment options include prolotherapy, platelet lysate and bone marrow derived stem cells.

The problems associated with surgical repairs have been previously discussed.

ACL tears have been successfully treated without surgery utilizing Regenexx SD, a bone marrow derived same day stem cell treatment.

If you have had an injury and your knee feels unstable understand that non surgical treatment options and evaluation is available to at Centeno-Schultz Clinic.
