INTRODUCTION –Anterior cruciate ligament (ACL) rupture is a common and devastating injury. Females are three times more likely to suffer an ACL rupture. Even though stability is restored after ACL reconstruction, half of the patients develop early-onset osteoarthritis (OA). The onset of OA is multifactorial and not fully understood. Altered gait patterns following ACL reconstruction may be associated with the onset of OA by shifting the loading endured by the knee cartilage. Little is known about the long term alterations in gait during running and the influence of fatigue on the kinematics of the ACL reconstructed knee. OBJECTIVES –The aim of this study was to gain insight into the kinematics of the female knee during running after ACL reconstruction and to hereby contribute knowledge on the development of OA in these patients. METHODS – 30 females (15 ACL reconstruction, 15 controls) participated in this study. Gait analysis was performed before and after fatigue. Between limb and group comparisons were made for peak knee angles in the sagittal, frontal and transverse plane during the stance phase of gait. RESULTS – The ACL reconstructed knees showed a significant smaller peak flexion compared to the contralateral uninjured knee (p=0,00) and the controls (p=0,03). Peak extension was larger for the ACL reconstructed knees compared to the controls but not different compared to the uninjured knees (p=0,02). ACL reconstructed knees were more externally rotated compared with uninjured knees (p=0,02) but in frontal plane no differences were found regarding knee kinematics. The internal rotation of ACL reconstructed knees increased more after fatigue compared to uninjured knees (p=0,01). CONCLUSION – On average 4 years after ACL reconstruction, female athletes show alterations in knee kinematics during running. Altered knee kinematics may be an important factor in the development of OA after ACL reconstruction.
