Abstract

Aim of this cadaveric biomechanical study was to describe the detailed anatomy of the static medial patellar stabilizers and further determine the role of each of them in preventing lateral patellar dislocation. Eight cadaver knees, after removing the skin and subcutaneous tissues, were used in the study. The medial patellofemoral ligament (MPFL), the medial retinaculum (MR) the medial patellomeniscal ligament (MPML), and the medial patellotibial ligament (MPTL) were dissected. Their origins, insertions, orientations and sizes were recorded. To the medial stabilizers, a tension of 10 pounds was applied, using a tensiometer held in a semicircular device while the knees were kept in 30 degrees of flexion. Then, the previously described ligaments were dissected and the resultant displacement recorded. The most anatomically distinct structure is the MPFL, whose length varies from 45-50 mm, and its width from 10-20 mm at its origin (medial femoral epicondyle) to 20-30 mm at its insertion to the patella. The "meshing" of the MPFL fibers to the fibers of the vastus medialis obliquus (VMO) close to its patellar insertion was the most interesting and very important finding. The contribution of MPFL to medial stability was more than 50%. Of the remaining ligaments, MPML contributes 24% and the MPTL and MR contribute only 13% respectively. The MPFL is the strongest medial static patellar stabilizer. Its contribution to patellar stability against lateral dislocation is far more than 50%, since its meshing with the VMO, shortens its fibers which thus pulls the patella to the medial part of the femoral groove and keeps it in the trochlea during the initial 20 degrees -30 degrees of flexion.

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 20 August 2015.
All research outputs
#6,981,301
of 12,215,443 outputs
Outputs from Knee Surgery, Sports Traumatology, Arthroscopy
#819
of 1,501 outputs
Outputs of similar age
#130,679
of 281,980 outputs
Outputs of similar age from Knee Surgery, Sports Traumatology, Arthroscopy
#19
of 49 outputs
Altmetric has tracked 12,215,443 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,501 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one is in the 44th percentile – i.e., 44% 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 281,980 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 53% of its contemporaries.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
