  1. Complication &ACL revision

  2. Time

  3. Intraop. complications

  4. Surgical tech. errors Tunnel placement Inadequate notchplasty Graft selection& size Tensioning Fix failure: Poor bone quality,screwbreakage,screw divergence & graft damage

  5. Tunnel malposition Femur Ant. Position & post. Position & vertical Tibial ant. & post position

  6. Blumensaat,s line

  7. Graft tensioning Inadequate tensioning Overtensioning Stiffnes Graft stretching Stress on cartilage Poor vascularity

  8. Fixation Screw Transfix endobutton

  9. Graft impingement Notchplasty Postop pain Bleeding Swelling regrowth

  10. Postop problems Persistent Ant Knee Pain 0 34% Motion deficits 1 13% Arthrofibrosis Graft failure Osteoarthritis DVT Infection

  11. Ant Knee pain Flex contracture>10 Q weakness BPTB G short imobilization,early &proper PT

  12. Loss of motion Tunnel malposition Prolonged immobilization Poor patient compliance RSD Too early recons. Inadequate notchplasty Concomitant surgery PT, steroid, manipulation,arthroscopy & revision
