Differences in cartilage composition and function have been reported following anterior cruciate ligament reconstruction (ACLR), compared to healthy individuals, likely due to changes in the physiological makeup of the cartilage, which can lead to post-traumatic osteoarthritis (PTOA). Brightness mode ultrasound (US) has recently been used to evaluate the deformation of femoral articular cartilage. The purpose of this study is to utilize US to compare the rate of recovery of femoral cartilage (resilience) cross-sectional area (CSA) after a 3,000-step walking protocol between individuals with ACLR and healthy controls, as well as to observe correlations between cartilage resilience of the ACLR group and various gait biomechanics outcomes. Serial US images were obtained in 15 individuals with ACLR and 15 healthy controls immediately, and at 5, 10, 15, 20, 30, and 45 minutes post-walking and assessed for total, medial, and lateral cartilage CSA. Gait biomechanics outcomes were collected at 2 minutes, 1,500 steps, and 2,500 steps into the walking protocol. There were no statistically significant differences in cartilage resilience between groups, although visual inspection suggests the control group returned to baseline after 15 minutes post-walking in the total, medial, and lateral regions. However, significant correlations were found between peak knee flexion angle at the 2,500 step timepoint and both total and lateral cartilage CSA resilience in those with ACLR. Trends towards significance were found between peak knee flexion angle at the 2,500 step timepoint and medial cartilage CSA slope, and between peak knee flexion angle displacement at the 2,500 step timepoint and total and lateral cartilage CSA resilience. Future research should be directed to further knowledge regarding the relationship between cartilage recovery and PTOA development and progression following ACLR.
