Abstract:

BACKGROUND: Arthroscopic reconstruction is a common method in the treatment of anterior cruciate ligament injury, in which tendon fixation is an important part.
OBJECTIVE: To investigate the clinical effect of absorbable screw fixation with autologous hamstring for anterior cruciate ligament reconstruction under arthroscopy.
METHODS: Totally 47 cases of anterior cruciate ligament reconstruction were included, containing 27 male patients and 20 female patients, aged from 18-48 years old, and all patients underwent the absorbable screw fixation with autologous hamstring implantation. After12-month follow-up, patients underwent Lysholm, Tegner, and IKDC scoring before treatment and after 1, 3, 6 and 12 months, respectively. Additionally, anterioposterior lateral X-ray and MRI reexamination were performed, and adverse reactions were recorded at 12 months after treatment.
RESULTS AND CONCLUSION: Postoperative knee instability symptoms such as “weak legs” walking gait recovered to normal levels, and the wound all reached the primary healing. Moreover, the Lysholm, Tegner and IKDC scores at 3, 6 and 12 months after treatment were significantly higher than those before treatment (P < 0.05). There were no incision infection, nerve injury, deep vein thrombosis and other adverse events except hemarthrosis of the knee joint in one case. After 12 months of treatment, the imaging examinations showed that there was no enlargement of the bone tunnel, and no significant change in the joint space. In conclusion, the absorbable screw fixation with autologous hamstring for the reconstruction of anterior cross ligament has good fixing effect and little trauma, and significantly improves the extremity function of patients.
