What works best for an ACL repair? Hamstring, patellar tendon or a cadaber

They all work well.: The three types of grafts all are acceptable in acl reconstruction. It really depends on what graft your surgeon is most comfortable using. As well as, whether you want to use your own tendons or if you care about a cadaver. Long term results are excellent using auto or allografts. ...Read more

Acl Reconstruction (Definition)

Because an acl (anterior cruciate ligament) cannot heal itself on its own, an acl is "reconstructed" by placing a graft tendon substitute (from your own or donor cadaver tendon) placed into tunnels made in the original acl position, and fixed in place with screws, buttons, or other fixation device. The body then replaces the cells and structure of the graft over 6-8 months, ...Read more

How strong is an allograft tendon for ACL reconstruction surgery?

Very strong: One criteria for an allograft and the way it is fixed is that's its strength need to be as strong as the original acl. At the time of surgery, if done properly, the pullout strength is higher than the native acl. As the body grows into the graft, there is some weakening, followed by strengthening when the graft matures. ...Read more

What is the strength of an allograft tendon after ACL reconstruction surgery?

What is the strength of an allograft tendon after ACL reconstruction surgery?

Depends.: Allograft tendons can be as strong or stronger then autograft tendons, depending on what you are comparing. Patella tendon autografts are "gold standard" but hamstring tendons are quickly being recognized as being just as good. One downfall to allografts is that it takes longer for your body to "ligamentize" the graft, however there are benefits to allografts as well. ...Read more

What is the strength like after an allograft tendon for ACL reconstruction surgery?

Quite strong: The strength of fixation for an allograft acl reconstruction varies on the type of fixation and individual surgeon technique, but in general the initial strength is similar or greater than the original native acl. Over time as the body replaces the allograft tissue, the graft becomes first weaker, then about the same strength as the original. This process takes about 8-9 months. ...Read more

What is the normal timetable for recovery from ACL reconstruction and meniscus repair using pateller tendon?

6-8 months: It takes around 8 months for your newly reconstructed acl to heal enough to allow for cutting and pivoting exercises, regardless of the type of tissue used to reconstruct the acl. The meniscus is healed enought after 6 weeks to allow you to walk with out your knee locked in extension. ...Read more

Had acl reconstruction on 1/8/2016 using a patellar tendon graft. My question is- Is it normal to lift your leg with tendon when muscles don't work?

Had acl reconstruction on 1/8/2016 using a patellar tendon graft. My question is- Is it normal to lift your leg with tendon when muscles don't work?

No: The answer is "No" because tendons don't contract... meaning they don't move on their own. The muscles contract. To move against gravity, such as lifting a leg, at least one muscle has to move. Otherwise, nothing happens. To move with gravity, such as letting a leg drop down, whatever muscles that were holding the leg up just have to relax or stop contracting... and the leg will drop. ...Read more

I had ACL reconstruction both knees- 2005 Left and 2009 right. Both are torn again 100%. Doctor suggests new surgeries by taking tendons from patella.

I had ACL reconstruction both knees- 2005 Left and 2009 right. Both are torn again 100%. Doctor suggests new surgeries by taking tendons from patella.

ACL tears: Its unfortunate that both are once again torn. You need the ACL for joint stability otherwise you will have to wear a knee stabilizer. I think repeat surgery is a reasonable option. You will have to be extremely careful once this is done. ...Read more
