Hamstring Injuries
-
grade 1 – a mild muscle pull or strain.
-
grade 2 – a partial muscle tear.
-
grade 3 – a complete muscle tear.
ACL Injury
-
ACL reconstruction surgery uses a graft to replace the ligament. The most common grafts are autografts using part of your own body, such as the tendon of the kneecap (patellar tendon) or one of the hamstring tendons. Sometimes the quadriceps tendon from above the kneecap is used. Another choice is allograft tissue, which is taken from a deceased donor.
-
Repair surgery typically is used only in the case of an avulsion fracture (a separation of the ligament and a piece of the bone from the rest of the bone). In this case, the bone fragment connected to the ACL is reattached to the bone.
-
ACL surgery is usually done by making small incisions in the knee and inserting instruments for surgery through these incisions (arthroscopic surgery). In some cases, it is done by cutting a large incision in the knee (open surgery).
