Abstract:

BACKGROUND: At present, there are a lot of controversial exists in the methods of anterior cruciate ligament reconstruction by different scholars. Looking for simple and economical repair methods is the research focus.
OBJECTIVE: To explore the clinical effect of arthroscopic anterior cruciate ligament (ACL) reconstruction with six-strand hamstring tendon autografts.
METHODS: Nineteen non-consecutive randomized patients with unilateral ACL insufficiency received six-strand hamstring tendon autografts reconstruction by using double tibia tunnel technique. Patients were evaluated subjectively and objectively before and after ACL reconstruction, using IKDC score, Lysholm score system, manual maximum displacement test with KT-2000TM arthrometer. Radiographic evaluation was performed according to IKDC grading system.
RESULTS AND CONCLUSION: The subjective and objective IKDC were 8 in A (42.1%), 10 in B (52.6%) and only 1 C (5.4%)and radiographic IKDC were 15 in A (78.9%), 3 in B (15.7%), 1 in C (5.4%). Passive range of motion recovery was within 120°-140° (average 126°). The measured data by KT-2000TM in normal and operated knee were 6.1±0.2 and 6.5±0.8, 6.3±0.5 and 7.1±0.9, 7.2±0.6 and 8.3±1.2, at the tensile fore of 20 pound, 30 pound and the largest, respectively. Lysholm score were 51.8±8.6 before operation and 86.5±12.3 at the last followed-up. The double bundle of ACL reconstruction by hamstring tendon autograft shows satisfactory functional results in the early period.
