ACL reconstruction with transtibial technique may increase risk for repeat knee surgery

Transtibial and anteromedial portal techniques for ACL reconstruction are not an indicator for quality of life outcomes, but the transtibial technique is a risk factor for repeat ipsilateral knee surgery up to 6 years of follow-up, according to results of this study.
“Patients undergoing ACL reconstruction with use of a transtibial technique to drill the femoral tunnel have increased odds of undergoing repeat ipsilateral knee surgery within the first 6 postoperative years compared with those who undergo reconstruction with an anteromedial portal technique,” Andrew Duffee, MD, and colleagues wrote in the study.
Duffee and colleagues analyzed results from 436 patients who underwent a primary isolated autograft ACL reconstruction with either a transtibial or anteromedial portal technique, according to the abstract. They used a multiple linear regression model to control for patient age, gender, body mass index, activity level, graft type, smoking status and presence of chondral and meniscal pathology at the time of surgery.
While the transtibial technique was not a predictor of the quality of life or function, sports and recreational activities subscore for the Knee Osteoarthritis Outcome Scores, the technique carried a 2.49 increased odds ratio for repeat ipsilateral knee surgery at 6-year follow-up, according to the abstract.
