Abstract

INTRODUCTION: Knee injuries are more common in the modern era due to increase in road traffic accidents and more involvement in sports related activities by common people. Anterior cruciate ligament is the most commonly injured ligament around knee joint. Anterior cruciate ligament has a pivot role in function and stability of the knee joint, being the primary stabilizer preventing the anterior translation of tibia over femur. Arthroscopic anterior cruciate ligament reconstruction has become the gold standard in the management of these injuries. AIM OF THE STUDY: To do comparative analysis of the functional outcome of Arthroscopic anterior cruciate ligament reconstruction using quadrupled hamstring graft with endobutton as femoral fixation device and bioabsorbable interference screw against titanium interference screw as tibial fixation devices respectively. MATERIALS & METHODS: This study is a retrospective and prospective study of 60 patients treated with arthroscopic anterior cruciate ligament reconstruction with quadrupled hamstring graft with endobutton as the femoral fixation device and titanium interference screw (no=30) and bioabsorbable interference screw (no=30) as tibial fixation device respectively between May 2012 and November 2013 at Institute of orthopaedics and traumatology, Rajiv Gandhi Government General Hospital, Chennai. Minimum age of the patient was 20 years and maximum age was 55 years with mean age of 31. Study group included 51 male patients and 9 female patients. Minimum duration after injury was 5 weeks and maximum duration since injury was 15 months. Minimum period of follow up was 6 months and maximum was 1.5 years. Of the 60 patients, 30 patients underwent arthroscopic assisted anterior cruciate ligament reconstruction with quadrupled hamstring graft with endobutton as femoral fixation device and tiatanium interference screw as tibial fixation device. Remaining 30 patients underwent arthroscopic assisted anterior cruciate ligament reconstruction with quadrupled hamstring graft with endobutton as femoral fixation device and bioabsorbable interference screw as tibial fixation device. All patients were operated under spinal aneasthesia. Except for 2 patients, postopearative period was uneventful for others. RESULTS: All patients are evaluated with Lysholm and Gillquist scoring at the end of 6 months. The maximum score achieved was 100 and minimum score was 56. Two patients in titanium interference group and one patient in bioabsorbable interference screw group lost to followup. Statistical analysis was studied using Yate’s corrected Chi-Square test. No significant differences were identified between the two screw typeswith respect to Lysholm and Gillquist scoring. The complication rates were also similar in the two groups. CONCLUSION: The clinical results associated with titanium interference screw and bioabsorbable interference screw are statistically similar. The complication rates associated with the two screws were also similar. The results of this comparative analysis support the hypothesis that there are no significant differences in the outcomes associated with tiaanium screws compared with bioabsorbable screws for ACL reconstruction.
