Abstract:

BACKGROUND: There are a variety of methods for internal fixation of femur based on hamstring tendon anterior cruciate ligament (ACL) reconstruction, such as internal button and interface screw. Each reconstruction has advantages and disadvantages.
OBJECTIVE: To retrospectively evaluate the medium clinical results of arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation.
METHODS: The 42 cases undergoing arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation in Department of Arthroscope and Sports Medicine, Second Affiliated Hospital of Inner Mongolia Medical College from May 2005 to June 2007 were followed up for at least 2.5 years. Evaluations were performed using Lyshlom score scale and IKDC2000 score scale.
RESULTS AND CONCLUSION: The patients were followed up for 3.1 (2.5-4) years. Preoperative Lyshlom score was (44.34±7.12) scores, and (86.60±6.48) scores at the final follow up; preoperative IKDC2000 score was (48.46+17.53) scores, and (92.42±5.87) scores at the final follow up. All score scales were significantly improved than preoperative scores (P < 0.01). Results showed that arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation can obtain favorable middle clinical results.
