Biomechanical Deficits at the Hip in Athletes With ACL Reconstruction Are Ameliorated With Neuromuscular Training

Abstract

Athletes with ACLR who are participating in an NMT program may ameliorate known hip biomechanical risk factors for an ACL injury.

Anatomic Features of the Tibial Plateau Predict Outcomes of ACL Reconstruction Within 7 Years After Surgery

“…The influence of patient-(e.g., age, activity level, sport participation), 10,12,43 surgical-(e.g., graft type, size), 3,18,20,25 and rehabilitation-related (e.g. neuromuscular and physical training) 23,37 factors on ACL reconstruction outcomes have been the focus of many research efforts. In contrast, little is known about how a patient's anatomical features of the knee joint may influence outcomes.…”

“…33,38,43 Accordingly, investigations of the factors affecting outcomes of ACL reconstruction are of great clinical significance to improve short- and long-term outcomes. The influence of various factors on ACL reconstruction outcomes—including those based on patients (eg, age, activity level, sport participation), 10,12,43 surgery (eg, graft type, size), 3,18,24,34 and rehabilitation (eg, neuromuscular and physical training) 22,37 —has been the focus of many research efforts. In contrast, little is known about how a patient’s anatomic features of the knee joint may influence outcomes.…”

Surgical versus conservative treatment for torn anterior cruciate ligament

“…It was determined that known hip biomechanical risk factors of ACL injury were significantly reduced among athletes with ACL reconstruction after the neuromuscular training program and that post-training hip biomechanics between the ACL reconstruction and control cohorts were not different. [5] Athletes who return to sports after ACL reconstruction demonstrate persistent biomechanical and neuromuscular deficits of the knee. Significant improvements in knee sagittal plane biomechanical measures were observed after the neuromuscular training program by athletes with ACL reconstruction.…”

Normalization influences knee abduction moment results: Could it influence ACL-injury research, too? Response to Letter to the Editor by Dr. Timothy E. Hewett

“…The inherent contradictions in these three statements notwithstanding, there are numerous examples in Dr. Hewett's publication record that are inconsistent with these stated views. For instance, he has: (1) compared normalized moments between groups that did not differ in height and mass [11][12][13] ; (2) compared non-normalized moments between groups that did differ in height and mass [14][15][16] ; and (3) used either non-normalized 3 or normalized 17 moments in logistic regression models to predict future injury risk. While there may be alternative explanations for why normalization was or was not applied in each of these instances, the methods used are seemingly at odds with his views regarding normalization put forward in the Letter to the Editor.…”
