Arthroscopic Anterior Cruciate Ligament Reconstruction Using Hamstring Graft with Endobutton Fixation-Results of Follow-Up

Between 1998 and 2000, 140 consecutive patients with primary diagnosis of anterior cruciate deficiency underwent arthroscopically assisted anterior cruciate ligament (ACL) reconstruction using autogenous quadrupled hamstring tendons. The graft fixation used the endobutton on the femoral site and screw and washer on the tibial site. The 5-8 year follow-up (mean 6.7) for clinical instability and laxity included 90 people (65 males, 25 females, mean age 22.7 years, range 18-29). Clinical assessment was performed using the modified Lysholm scoring scale and the International Knee Documentation Committee (IKDC) rating system. The clinical results for the Lysholm rating system were 91% good to excellent, while for the IKDC rating system they were 85% good to excellent. The results of the Lachman and pivot shift tests between pre-and post-operative were statistically significant (P＜0.05). Eighty-two of the 90 knees surveyed achieved full post-operative range of motion while variable loss of flexion was evident in eight patients. Anterior tibial displacement was ＜3mm in nearly 90% of cases and degeneration was evident in ＜15% of cases. Isokinetic quadriceps strength and peak torque testing demonstrated no significant postoperative difference (P＜0.05) between legs. We conclude that Endobutton devices achieve good clinical outcomes.
