ACL Scars and Weak Hamstrings


A young athletic footballer came in after being referred by a friend. They had been dealing with leg “weakness” and “heaviness” in their right leg for about 18months after having an ACL reconstruction on their right knee. We did some investigation around the knee and hip. We found that the scar below his knee that the surgeons used to pull his new ACL through was facilitated and neurologically over-active. This facilitation made the same side glute max and medial hamstrings, painful, inhibited and neurologically under-active. Using NKT protocols we released the scar and activated the Glute and Hamstrings. We then retested. The glute and hamstrings were now functional and pain free. This client will need to back off the loading for 2 weeks whilst they work on the scar and gain motor control back into the leg. Once this dysfunction has been reprogrammed they’ll be back to 100% once again.

A tip for anyone that has had ACL surgery. If your the scar on your leg below your knee feels “weird” or  “awkward” then you’ll probably (100% chance) have some sort of dysfunction. Its very likely that the hamstrings they grafted will be inhibited. If you have constant hamstring tension in that one leg or it feels heaps weaker then the other, try doing some light friction massage on the scar for 30sec followed by light activation of the hamstring. Do this twice a day for 2 weeks and watch the difference it’ll make! Just don’t do it before exercise or training as you need to earn the right to use your hamstring again. If you overload a weak hamstring it will tear.

If you have any concerns about your post ACL leg / hamstring please feel free to book in for an NKT assessment.
