Background: Functional exercises such as distance hop, squatting and gait are important in the rehabilitation of anterior cruciate ligament deficient and reconstructed individuals but movement compensations and incomplete recovery persist. This study aimed to; 1. Identify how these tasks pose different challenges; 2. Evaluate if these activities challenge anterior cruciate ligament groups differently compared to controls. Methods: Motion and force data were collected during distance hop, squatting and gait for 20 anterior cruciate ligament deficient, 21 reconstructed and 21 controls. Findings: For all groups knee range of motion was greatest during squatting, intermediate during hopping and smallest during gait (p < 0.01). Peak internal knee extensor moments were greatest during distance hop (p < 0.01). The mean value of peak knee moments were reduced in squatting and gait (p < 0.01) compared to hop. Peak internal extensor moments were significantly larger during squatting and external adductor moments during gait (p < 0.01). Fluency was highest during squatting (p < 0.01). Anterior cruciate ligament demonstrated good recovery of gait but anterior cruciate ligament deficient adopted a strategy of increased fluency (p < 0.01). During squatting knee range of motion and peak internal knee extensor moment were reduced in anterior cruciate ligament (p < 0.01). Both anterior cruciate ligament groups hopped a shorter distance (p < 0.01) and had reduced knee range of motion (p < 0.025). Anterior cruciate ligament reconstructed had reduced fluency (p < 0.01). Interpretation: Distance hop was the most challenging activity; squatting and gait were of similar difficulty but challenged patients in different ways. Despite squatting being an early, less challenging exercise, anterior cruciate ligament groups demonstrated numerous compensation strategies, indicating that this may be more challenging for anterior cruciate ligament than gait.
