Abstract:

BACKGROUND: There are a lot of debates on selections of grafts and ways of fixation methods about ansterior cruciate ligament (ACL) reconstruction. Each fixation has its advantages and disadvantages.
OBJECTIVE: To evaluate the effectiveness of allogeneic deep froze tendon of lower limb with one-end bone block in ACL reconstruction.  
METHODS: Fifteen knees with ACL tear, of which, 7 knees were caused by athletic injury, 6 knees by traffic accident, and 2 knees by falling. ACL tear was verified by arthroscopy, and all the damaged ACL were reconstructed with allograft tendons by inserting technique under arthroscopy. The value of KT-1000 and the Lysholm scores were recorded before operations and at follow-up.
RESULTS AND CONCLUSION: All cases were followed up for 12-24 months. No severe complication, such as vascular nerve injury, rejection or infection, occurred. The KT-1000 measurement showed that the preoperative difference of anterior laxity was 3-5 mm in 4 cases (27%), 6-9 mm in 9 cases (60%), and greater than 10 mm in 2 cases (13%); in the final followed up, difference of anterior laxity was 0-2 mm in 12 cases (80%), and 3-5 mm in 3 cases (20%). Lysholm score was remarkablely improved from (65.60±10.13) preoperatively to (90.93±4.06) at follow-up (P < 0.05). The reconstruction of ACL by inserting technique with allograft tendons can increase reliability of femoral side fixation, and the outcome is satisfactory.
