Study of outcomes after surgical reconstruction of knee's anterior cruciat ligament (ACL) useing Hamstring-tendon autografts in patients of army's Fajr & 501 hospitals from Septamber 2010 to March 2012: 64 cases

The aim of this study was to assess the outcomes after reconstruction of knee’s anterior cruciat ligament (ACL) using Hamstring-tendon autografts. 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. 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%) was<8 mm، in 12 patients (18. 75%) >8mm 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. Hamstring-tendon autografts in ACL-reconstraction was along with increasing laxity in womens and young people but it has little donor site morbidity.
