| Abstract |
To determine the influence of anatomical features of both the tibia and femur on quantitative pivot shift of anterior cruciate ligament (ACL)-injured patients. Fifty-three consecutive ACL-injured patients (mean age 26 ± 10.1 years, 36 males) who underwent ACL reconstruction were prospectively enrolled. Two blinded observers measured the parameters of medial and lateral tibial slope, femoral condyle width, notch width, bicondylar width and tibial plateau width on magnetic resonance imaging. The same examiner performed pivot shift under anaesthesia, while a previously validated image analysis technique was used to quantify knee kinematics during examination. The median lateral compartment translation detected during pivot shift testing (2.8 mm) was used to classify patients into "low-grade rotatory laxity" (≤2.8 mm) and "high-grade rotatory laxity" (>2.8 mm) groups. Twenty-nine subjects were grouped as "low-grade rotatory laxity", and 24 subjects were grouped as "high-grade rotatory laxity". Of the tested bone morphologic parameters, lateral tibial plateau slope was significantly greater in "high-grade rotatory laxity" group (9.3° ± 3.4°) compared to "low-grade rotatory laxity" group (6.1° ± 3.7°) (p < 0.05). Lateral tibial plateau slope was a significant predictor of "high-grade rotatory laxity" (odds ratio 1.27, p < 0.05). A tibial slope of 9° and greater predicted "high-grade rotatory laxity" (sensitivity 63 %; specificity 72 %). Increased slope of the lateral tibial plateau might be an important anatomical variable predicting high-grade rotatory laxity in patients with ACL injury. The finding can be useful in the clinical setting in predicting potential non-copers to conservative therapy and aid in the individualization of the reconstructive procedures of patients. Prospective diagnostic study, Level II. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 13 May 2016.
All research outputs
#14,261,557
of 22,869,263 outputs
Outputs from Knee Surgery, Sports Traumatology, Arthroscopy
#1,582
of 2,652 outputs
Outputs of similar age
#159,576
of 298,735 outputs
Outputs of similar age from Knee Surgery, Sports Traumatology, Arthroscopy
#29
of 51 outputs
Altmetric has tracked 22,869,263 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,652 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 36th percentile – i.e., 36% 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 298,735 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 43rd percentile – i.e., 43% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 51 others from the same source and published within six weeks on either side of this one. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
