Rebuilding the ligament: Most ACL tears cannot be sutured (stitched) back together, so to surgically repair the ACL and restore knee stability the ligament must be reconstructed. Dr Bhimani will replace your torn ligament with a tissue graft. This graft acts as scaffolding for a new ligament to grow on.
Grafts can be obtained from several sources. Often they are taken from the patellar tendon, which runs between the kneecap and the shinbone. Hamstring tendons at the back of the thigh are a common source of grafts. Sometimes a quadriceps tendon, which runs from the kneecap into the thigh, is used. Finally, cadaver graft (allograft) can be used.
There are advantages and disadvantages to all graft sources. You should discuss graft choices with Dr Bhimani to help determine which is best for you.
Because the regrowth takes time, it may be six months or more before an athlete can return to sports after surgery.
