Question:
My son had ACL Reconstruction surgery, Arthroscopy,partial lateral menisceotomy, ACL replacement using autogenous patella, patella tendon, tibial tubercle graft,This surgery was in june 1995, He has had no problems with his knee since surgery, he was 15 yrs. old at time of surgery. Played football, baseball, the rest of his high school years. Was planning on joining the armed forces, but they turned him down because he has had this ACL surgery. Was just wondering about the interference screws? Are they still there? Do they just dissolve or what after healing takes place inside of knee to replace them?

Answer:
I am not in the service and therefore do not know their policies. In the past, I was aware of patients HAVING ACL surgery to allow them to enter the service. There was required documentation of the associated injuries and post operative function. Regarding interference screw fixation, there are three general materials used: bioabsorbable, metal and allograft bone. The first gradually resorbs, the second remains unless surgically removed and the last is gradually assimilated by creeping substitution by the host (patient). The screws are no longer necessary after healing of the graft in the tunnels--approximately 6 weeks if all goes without a problem.
