INTRODUCTION: Aberrant knee mechanics during gait 6 months after anterior cruciate ligament reconstruction (ACLR) are associated with markers of knee cartilage degeneration. The purpose of this study was to compare loading during walking gait in quadriceps tendon, bone-patellar tendon-bone (BPTB), and hamstring tendon autograft patients 6 months post-ACLR using loadsol single sensor insoles, and to evaluate associations between loading and patient-reported outcomes.
METHODS: Seventy-two patients (13 to 40 yr) who underwent unilateral, primary ACLR with BPTB, quadriceps tendon, or hamstring tendon autograft completed treadmill gait assessment, the International Knee Documentation Committee (IKDC) survey, and the ACL-Return to Sport after Injury (ACL-RSI) survey 6 ± 1 months post-ACLR. Ground reaction forces were collected using loadsols. Limb symmetry indices (LSI) for peak impact force (PIF), loading response instantaneous loading rate (ILR), and loading response average loading rate (ALR) were compared between groups using separate analyses of covariance. Survey scores were compared between groups using one-way ANOVAs. The relationships between IKDC, ACL-RSI, and LSI were compared using Pearson's product moment correlation coefficients.
RESULTS: There were no significant differences between graft sources for LSI in PIF, ILR, ALR, or impulse. Patient-reported knee function was significantly different between graft source groups with the BPTB group reporting the highest IKDC scores; however, there was no significant difference between groups for ACL-RSI score. There were no significant associations between IKDC score, ACL-RSI score, and biomechanical symmetry among any of the graft source groups.
CONCLUSIONS: Autograft type does not influence PIF, ILR, ALR, or impulse during walking 6 months post-ACLR. Limb symmetry during gait is not strongly associated with patient-reported outcomes regardless of graft source. Loadsols appear to be a suitable tool for use in the clinical rehabilitation setting.
