| Abstract |
The aim of this study is to determine how selected gait parameters may change as a result of anterior cruciate ligament (ACL) deficiency and following ACL reconstruction. The study was performed on 25 ACL-deficient subjects prior to and 6 weeks, 4 months, 8 months and 12 months after ACL reconstructive surgery by the bone-patellar tendon-bone technique. Gait analysis was performed using the zebris three-dimensional ultrasound-based system with surface electromyograph (zebris Medizintechnik GmbH, Germany). Kinematic data were recorded for the lower limb. The muscles examined include vastus lateralis and medialis, biceps femoris and adductor longus. The results obtained from the injured subjects were compared with those of 51 individuals without ACL damage. The acute ACL-deficient patients exhibited a quadriceps avoidance pattern prior to and 6 weeks after surgery. The quadriceps avoidance phenomenon does not develop in chronic ACL-deficient patients. In the individuals operated on, the spatial-temporal parameters and the knee angle had already regained a normal pattern for the ACL-deficient limb during gait 4 months after surgery. However, the relative ACL movement parameter-which describes the tibial translation into the direction of ACL-and the EMG traces show no significant statistical difference compared with the values of healthy control group just 8 months after surgery. The results suggest that: (1) development of a quadriceps avoidance pattern is less common than previously reported, (2) anterior cruciate ligament deficiency and reconstruction significantly alter the lower extremity gait pattern, (3) the gait parameters shift towards the normal value pattern, and (4) the re-establishment of pre-injury gait patterns--including the normal biphase of muscles--takes at least 8 months to occur. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 August 2014.
All research outputs
#17,286,645
of 25,374,917 outputs
Outputs from Knee Surgery, Sports Traumatology, Arthroscopy
#1,999
of 2,934 outputs
Outputs of similar age
#51,241
of 56,713 outputs
Outputs of similar age from Knee Surgery, Sports Traumatology, Arthroscopy
#6
of 6 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,934 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 56,713 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 5th percentile – i.e., 5% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one.
