ABSTRACT
PURPOSE:
The purpose of this study was to clarify the difference between the remnant-preserving and remnant-sacrificing techniques in anterior cruciate ligament (ACL) reconstruction using stress test, functional score, 2nd look arthroscopy and magnetic resonance imaging (MRI). MATERIALS ANDMETHODS:
Among 66 patients having anatomical ACL reconstruction with the fourstrand hamstring autograft using outside-in technique (FlipCutter(R)) for the femoral tunnel from April 2012 to April 2014, 23 patients who underwent 2nd look arthroscopy and MRI were included. The remnant-preserving group included 12 patients and the remnant-sacrificing group included 11 patients. The two groups were compared and analyzed with regard to stability (Stress test using GNRB(R), pivot shift test), functional assessment (International Knee Documentation Committee [IKDC] scale, Lysholm score, one leg hoop test), and the result of second-look arthroscopy and signal to noise quotient (SNQ) ratio of the graft in MRI.RESULTS:
The two groups did not differ significantly in the stability test, IKDC scale, and Lysholm test. The remnant-preserving group showed significant improvement in one leg hoop test compared with the remnant-sacrificing group (p0.05).CONCLUSION:
More than 12 months after surgery, the graft of the remnant-preserving group showed lower signal intensity compared to that of the remnant-sacrificing group by MRI evaluation. The remnant preserving technique has biological difference compared with the remnant sacrificing technique in human study.
