Reconstruction of the anterior cruciate ligament: a comparison between XXXX grafts and fourstrand hamstring grafts.

@entity1 @entity79 @entity158 @entity12352
BACKGROUND: Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of @entity79 ( @entity79 ) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up interval. METHODS: Seventy-one @entity1 with an average age of 29   4.5yearswere treated for torn ACL between 2008 and 2009. Forty-sixpatients underwent reconstruction with @entity79 autograft, and 41 were treated with ST autograft. At the time of final follow-up, 37 @entity1 in @entity12352 group and 34 @entity1 in hamstring group were evaluated in terms of return to pre-injury activity level, @entity158 , knee stability, range of motion, IKDC (International Knee Documentation Committee) score and complications. RESULTS: At 36thmonth of follow-up, 34 (92%) and 28 (82%) @entity1 in @entity79 and ST group, respectively had good-to-excellent IKDC score (p > 0.05). The activity levels were higher in @entity79 group (p> 0.05). At 3rd yearof follow up, the Lachman test was graded normal, for 23 (62%) and 11 (32%) @entity1 in @entity79 and ST group, respectively (p=0.019). Regarding the pivot-shift test, 29 (79%) and 15 (44%) @entity1 in @entity12352 and hamstring group, respectively had normal test at the latest follow-up (p=0.021).There were no significant differences in terms of thigh circumference difference, effusion, knee range of motion, @entity158 and complications. CONCLUSION: The results indicate a trend toward increased graft laxity and pivot-shift grades in @entity1 undergoing reconstruction with hamstring autograft compared with @entity12352 tendon. However, the two groups had comparable results in terms of activity level and knee function.
