The purpose of this study is to compare failure rate and functional outcome in young, active patients (< 25 years) with two-incision (rear-entry) versus transtibial (all-endoscopic) anterior cruciate ligament (ACL) reconstructions.Utilizing a computerized relational database (Access 2007, Microsoft Inc., Redmond, WA), 480 patients were identified that underwent ACL reconstruction, using a bone-patellar-tendon-bone autograft, by a single surgeon between January 2000 and December 2010 via a transtibial or two-incision technique. Totally, 377 (78.6%) of these patients were less than 25 years of age. Data for each patient were collected at their initial clinic visit, at the time of surgery, and at each follow-up clinic visit and entered into the computerized relational database. Overall, 274 patients (72.7%) underwent ACL reconstruction with a transtibial technique, and 103 patients (27.3%) underwent reconstruction with a two-incision technique. Failures were identified as a 2+ Lachman, 1+ or greater pivot shift, or a KT-1000 arthrometer difference of five or more.In patients Our study showed no statistical difference between the two-incision technique and the transtibial technique for ACL reconstruction using bone-patellar-tendon-bone autograft with an overall 10.1% failure rate in young, active patients (< 25 years of age). The level of evidence is level IV.

This study assessed the relationship between body mass index (BMI), anterior cruciate ligament (ACL) injury, and associated meniscal and cartilage injury. Age, ACL classification, and Tegner activity score were considered. A total of 1968 ACL reconstruction patients (2/1/1996 to 5/1/2012) were analyzed. All graft types, age groups, and activity levels were included. A BMI ≥30 correlated with a significant likelihood of medial meniscus tears (p = .022). Patients with a BMI ≥30 were 21.6% more likely to have a medial meniscus tear with an ACL injury. Grade III and IV chondral lesions correlated with a BMI ≥30 (p = .029). Patient's age predicted medial meniscus outcome (p = .013). Patients whose age was >25 had a 25.7% higher risk of medial meniscus tear. Chronic ACL patients were 52.6% more likely to have a meniscus injury. BMI, age, Tegner activity score, and ACL classification are good predictors of medial meniscus injury. Patients with a BMI ≥30 exhibit a greater risk of medial meniscus tear with ACL instability; however, BMI does not significantly contribute to increased chondral damage in ACL-deficient patients.
