Description of intervention(s) / exposure
Asymmetries in the lower limbs are easy to see at patellar level as a longitudinal
misalignment of the patellar borders. A statistical measurement of this misalignment has never been carried
out. In this study, we have used a new instrument, invented by us, to measure the longitudinal misalignment
of the upper borders of the patella. This instrument has been called "Dismetrometro". The name "Dismetrometro" comes from the term dysmetria. The Dismetrometro is an instrument for measuring misalignments. Using our instrument in this study, we carried out the statistical measurement of
the misalignment of the patellar borders. During our study we assessed 100 healthy individuals using the Dismetrometro device. Each individual had a negative anamnesis for orthopaedic pathologies of the lower limbs. Data collection was been completed in one month.

Comparator / control treatment
Three different operators (OP1, OP2, OP3) measure the same sample of subjects three times (first session). This procedure is repeated after one week (second session). The measurements collected in the dataset are in millimetres to one decimal point.
The patellar superior border misalignment measurements are performed by three different operators for all subjects.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 3465 0
Evaluate the efficiency, efficacy of measurements carried out with this new type of calliper: Dismetrometro
Timepoint [1] 3465 0
The measurement trial consisted of two following sessions. The second session was carried out a week apart. In each session three different operators have measured the misalignment in every subjects.
Secondary outcome [1] 5781 0
Evaluate the reproducibility of measurements carried out with this new type of calliper: Dismetrometro
Timepoint [1] 5781 0
In order to verify the repeatability and reproducibility of the measurements over time, the same session procedure was performed after seven days.

Summary
Brief summary
The Dismetrometro is an instrument for measuring misalignments. Using this instrument, we carried out the statistical measurement of the misalignment of the patellar upper borders.
During our study we assessed 100 healthy individuals using the Dismetrometro device. Each individual had a negative anamnesis for orthopaedic pathologies of the lower limbs. The average measurement of the
vertical distance between the two sides was 6.9 +/- 0.5 mm (S.D). This measurement is irrespective of gender and age, repeatable over a period of time and reproducible between different operators.
