Age, graft size, and Tegner activity level as predictors of failure in anterior cruciate ligament reconstruction with hamstring autograft.
Several factors are associated with failure after an Anterior Cruciate Ligament (ACL) reconstruction with hamstring autograft. This study (population = 98) investigated whether age, graft size or Tegner activity level are predictors of failure. Failure was defined as 2+ Lachman, positive pivot shift, and 5-mm or larger difference on the KT-1000 arthrometer measurement or revision surgery.
Failure was found in 15 patients (15,3%). Younger patients (age 25 and below) demonstrated higher failure rates compared to older patients (age above 25). No other correlation between failure rate and one of the other parameters (graft size and Tegner activity level) was found in contrast to several other studies. This could be due to the small number of patients which limits the ability to detect differences > From Kamien et al., Am J Sports Med. 41(8) (2013) 1808-1812.
