Study of outcomes after reconstruction of knee’s anterior cruciate ligament (ACL) using Hamstring-tendon autografts from Septamber 2010 to March 2012: 64 cases

Background: The aim of this study was to assess the outcomes after reconstruction of knee’s anterior cruciat ligament (ACL) using Hamstring-tendon autografts. Materials and Methods: In this descriptive study from Septamber 2010 to March 2012, 64 (62 Male and 2 Female) patients from Fajr and 501 hospitals of Iranian military hospitals were included. Pre- and postoperative conditions were similar and one surgeon performed all operations. Patient’s data were collected with blanks and objective assessments to case-series forms was filled at pre- and postoperation. Visits performed at 3, 6 month and 1 year after surgery. Assessments were included: time from trauma to surgery, accompanied traumas with subjective and objective features. Results: Time-average of trauma to surgery was 9. 3 (range: 3 weeks-18 month). Meniscal injury was existed in 45 patients (70.31%) that was higher than the similar studies. Accompanying condral injury was in 27 patients (42.18%). 80% of patients were returned to the pre-injury functional levels. Postoperative static laxity with Lachman test in 50 patients(78. 12%) was8mm with hard end point and only in 2 patients(3. 12%) was >10mm with soft end point. At the last postoperative visit, 59 patients (92.18%) do not have any pain in operated knee. Preoperative giving way was in all of patients but postoperative giving way was seen only in 2 (3.12%). None of patients did not have any limitation in extension but limitation in flexion was existed only in 3 (4.68%) and it was less than 25 degree. There was no case of graft rupture. Conclusion: Hamstring-tendon autografts in ACL-reconstraction was along with increasing laxity in womens and young people but it has little donor site morbidity.
