Poorer dynamic postural stability in patients with anterior cruciate ligament rupture combined with lateral meniscus tear than in those with medial meniscus tear

“…The results of the present study also showed that there were no significant differences in static and dynamic postural stability between the involved and uninvolved side knees in each group. The result of the current study might have originated from bilateral impairment of postural stability following a unilateral ACL or meniscus injury [20]. Previous studies have delineated that decreases of afferent neural signal input to the central nervous system after an injury of one limb resulted in loss of motor output in the opposite limb, thus leading to bilateral impairment [32,34].…”

“…Based on a previous study for postural stability in patients with knee joint injuries [18,20], an OSI difference > 0.5 between the ACL rupture combined with MM tear and combined with LM tear groups was considered . Each subject was seated on the device, with hips and knees flexed to 90°and trunk perpendicular to the floor.…”

“…Previous studies have delineated that decreases of afferent neural signal input to the central nervous system after an injury of one limb resulted in loss of motor output in the opposite limb, thus leading to bilateral impairment [32,34]. Park et al [20] denoted that there was no significant difference in postural stability between the involved and uninvolved side knees in patients with ACL tear combined with meniscus tears, and the authors also suggested that bilateral impairment of postural stability is more severe in the ACL tear combined with meniscal tear group compared with the isolated ACL tear group. Therefore, we recommend that balance training should be emphasized during preoperative and postoperative rehabilitation programs for the uninvolved side knees as well as the involved side knees in patients with ACL rupture combined with meniscal tears.…”

Somatosensory Function Influences Aberrant Gait Biomechanics Following Anterior Cruciate Ligament Reconstruction

“…We did not control for the presence of concomitant meniscal injury. However, somatosensory function following ACLR reportedly is not influenced by this factor, and recent data suggest similarity in gait biomechanics and cartilage morphology in ACLR patients with and without meniscal pathology . Lastly, we only evaluated gait biomechanics outcomes during weight acceptance, but somatosensory dysfunction could also be associated with the swing phase and late stance phase biomechanics.…”

Eccentric Exercise, Kinesiology Tape, and Balance in Healthy Men

“…Indeed, comparison with data obtained in clinical cohorts indicated that the balance deterioration provoked by downhill walking (OSI before downhill walking ¼ 2.58, OSI after downhill walking ¼ 2.98) was only slightly smaller than that caused by rupture of the anterior cruciate ligament (OSI ¼ 0.58-0.78). 35,36 The impaired balance may be related to desensitization of muscle spindles or Golgi tendon organs provoked by physical fatigue. 6,31 Our finding that balance results were virtually unchanged after the eccentric exercise intervention when KT was applied to the knee suggests that use of this tape may counter the negative effect of physical exertion, thereby limiting or even preventing exercise-related impairment of balance ability.…”
