Graft tensioning methods. In Group I, the two tibial ends were simultaneously fixed at 30° of knee flexion with 2 spiked-staples, applying a total of 80 N load (a 40 N load to each graft) for 2 min using a custom-made spring-type tensiometer. In Group II, the two tibial ends were simultaneously fixed at 10° of knee flexion with same method, applying a total of 60 N load (a 30 N load to each graft)
