| Abstract |
Patients with knee osteoarthritis tend to modify spatial and temporal parameters during walking to reduce the pain. Total knee arthroplasty (TKA) is considered the gold standard treatment for end-stage knee osteoarthritis. However, reduced physical function of the knee is partly, but apparently not fully, remedied by surgery. The purpose of this study was to investigate the in vivo, three dimensional knee kinematics during gait at the patients with knee osteoarthritis and the influence of "third condyle" psoterior stabilized (PS) total knee arthroplasty on restoration of normal kinematics. Twenty patients with medial knee osteoarthritis and a control group with age-matched subjects were prospectively collected for this study. The same group of 20 patients were re-assessed 10 months after total knee arthroplasty with "third condyle" PS prosthesis. All subjects were assessed with a 3D, optoelectric knee assessement device, while walking on a treadmill at a self-selected speed. For each participant, knee flexion-extension, abduction-adduction, internal-external rotation and anterior-posterior displacement, were calculated. The range of flexion/extension was improved significantly (39.9° ± 5.5° vs 44.8° ± 5.1°, p < 0.05) after TKA but it still remained lower than control group (6.9° ± 5.5° vs 2.2° ± 3.9°, p < 0.05). The range of motion in internal-external rotation did not change pre- and post-arthroplasty, but remained lower than the matched control group (6.7° ± 2.4° vs 9.3° ± 2.4, p < 0.05). The maximum posterior displacement during swing phase was significantly higher at post-arthroplasty group comparing with control group (-9.5 ± 2.2 vs -5.7 ± 3 mm, p < 0.05). Following "third condyle" PS-TKA, patients had better clinical, spatiotemporal and kinematic parameters. Despite improvements, the knee kinematics during gait in TKA group differed from healthy control group. TKA group had a lower extension lower range of axial rotation and an increased tibial posterior displacement. |

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 26 April 2017.
All research outputs
#16,049,105
of 23,815,455 outputs
Outputs from Archives of Orthopaedic and Trauma Surgery
#737
of 1,215 outputs
Outputs of similar age
#261,471
of 424,480 outputs
Outputs of similar age from Archives of Orthopaedic and Trauma Surgery
#11
of 16 outputs
Altmetric has tracked 23,815,455 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,215 research outputs from this source. They receive a mean Attention Score of 4.0. This one is in the 25th percentile – i.e., 25% 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 424,480 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 29th percentile – i.e., 29% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
