Assessment of Aerobic Fitness Following Anterior Cruciate Ligament Rupture and Reconstruction

Following anterior cruciate ligament rupture, physical activity may be limited due to restrictions placed on the patient while awaiting reconstruction (anterior cruciate ligament reconstruction [ACLr]). The purpose of the study was to evaluate aerobic fitness in individuals undergoing ACLr at the time of medical clearance following injury, 6-month post-ACLr, and 12-month post-ACLr. Seventeen individuals participated in the research study to completion (females, n = 6, age = 23.3 ± 5.5 years; males, n = 11, age = 23.2 ± 4.7 years). There were no changes in aerobic fitness from baseline to 12-month postoperative, but due to the length of time between injury and baseline assessments, it is unknown if aerobic deconditioning occurred before the patient was assessed preoperatively.
