Comparative study between hamstring versus bone patella tendon autograft to assess the functional outcome of arthroscopic reconstruction of ACL

BACKGROUND: ACL injury rate is around 60 per 1,00,000 people per year, with increase in sports activity this number is likely to go up. In recent years with recent advances in arthroscopic ACL reconstruction it is noted that 90% of athletes have chance of returning to their pre injury level of sports activity. INTRODUCTION: Anterior cruciate ligament (ACL) Reconstruction have undergone series of evolution over the past 30 years to improve the biomechanics of knee joint. In 1970’s surgery was done to repair the torn ends of the ligaments. After that, repair of ACL using autografts was done in 1980’s using arthrotomy (open procedure). In recent times, ACL reconstruction using autografts using arthroscopic procedure is universally accepted treatment for ACL injuries. ACL injury rate is around 60 per 1,00,000 people per year1, with increase in sports activity this number is likely to go up. In recent years with recent advances in arthroscopic ACL reconstruction it is noted that 90% of athletes have chance of returning to their pre injury level of sports activity. AIM OF THE STUDY: Comparative study between Hamstring versus Bone Patella Tendon Autograft to assess the functional outcome of Arthroscopic Reconstruction of ACL done at Govt. Stanley Medical College and Hospital Chennai, from period of June 2015 to May 2017. MATERIALS AND METHODS: In this prospective study we analysed 20 patients who were diagnosed to be having ACL tear and was treated with arthroscopic reconstruction of ACL out of which 10 cases were done using semitendinous graft and 10 cases by bone patellar tendon graft. The study was conducted in GOVT. Stanley Medical College and Hospital, Chennai from June 2015 to May 2017 with minimum follow up of 4 months and maximum follow up of 12 months. All 20 cases were male. CONCLUSION: The claimed advantage of hamstring graft is that it has less donor site morbidity than bone patellar tendon, it is therefore associated with anterior knee pain and pain on knee. In our study there were same post operative protocol followed for both the sets of patients. The p value between the two groups is not significant it is >0.05, and therefore the functional outcome of these groups were similar in this study
