ACL Recovery and Long Term Effects on Cartilage
There are about 100,000 knee ACL tears each year in the United States and many of them get a new surgically implanted ACL knee ligament followed by a long ACL surgery recovery. As I’ve discussed, the new knee ACL ligament isn’t like the old equipment, in that it goes in at too steep an angle. Even worse, some studies show that knee ACL replacement surgery is no better than physical therapy.
Now a new study shows that the cartilage in the knee isn’t well protected by the new surgically replaced knee ACL. In this new research they took 15 post ACL surgery patients and imaged them with a 3.0T research grade MRI at 1 and 2 years post procedure. They measured important MRI values that indicate good and healthy cartilage. What did they find? Well, regrettably, most of the cartilage in the ACL reconstructed knees was worse off after 2 years compared to healthy patients. Had maybe one area been worse, you could theorize that this spot was perhaps hurt in the original ACL injury. However, the fact that almost all areas measured were worse indicates that something else is going on. What? My personal opinion is that the abnormal motion of the knee due to the common wrong angled ACL replacement is causing excessive forces on the cartilage leading to breakdown.
The upshot? Avoid ACL replacement and ACL surgery recovery where possible! We’ve had good luck with fixing partially torn and non-retracted complete tears through a needle with stem cells. In addition, some studies show that physical therapy may work just as well as surgery in the short to medium term.
