Relationship between Changes in Physical Activity and Knee Health 18 Months after ACL Reconstruction.

ABSTRACT:

Purpose

This study aimed to determine the relationship between changes in daily physical activity (PA) and knee health 18 months after anterior cruciate ligament reconstruction (ACLR). Knee health was defined using structural (quantitative magnetic resonance imaging) and functional (patient-reported and objectively measured knee function) constructs.

Methods

Eighteen individuals (83.3% female, 19.7 ± 5.6 yr old, BMI 23.9 ± 3.7 kg·m -2 ) completed testing. Daily steps over 1 wk and structural cartilage health, measured using a waist-worn accelerometer (Actigraph wGT3X-BT; ActiGraph Corp., Pensacola, FL) and T2 relaxation time on magnetic resonance imaging, respectively, were collected 6 and 18 months after ACLR. Eighteen months after ACLR, patient-reported and objectively mea
