Study summary

The Thermo-LCA study is a diagnostic interventional study for assessment of knee temperature of asymptomatic patients with ACL reconstruction compared with unoperated healthy contralateral knee. The aim of the study is to analyze thermographic images obtained from the knees of asymptomatic patients with ACL reconstruction that occurred between the previous 2 and 5 years, to assess the presence of inflammation in the knee with reconstructed ACL compared with the contralateral.

Read the detailed description

Thermo-LCA study involves recruitment of thirty volunteers with unilateral ACL reconstruction Will be enrolled subjects aged 18 to 40 years, with no history of previous surgery or chronic gonalgia in the contralateral knee. Once the patient's Informed Consent has been obtained, the patient will wait sitting 10 minutes inside the temperature-controlled room of 23°C, a thermographic assessment will then be performed using a FLIRT1020 thermal imaging camera. Photographs will be acquired in anteroposterior, right lateral, left lateral, and posteroanterior views of both knees. The patient will then perform a knee flexion-extension exercise against resistance for 2 minutes using a 2 kg weighted ankle monitor. The speed at which this exercise is performed will be constant for all subjects, with one repetition per second per leg. Following this exercise, four more thermographic images identical to the first will be acquired. Basal thermographic assessments will be performed at 5', 10' and 20' minutes after the end of the exercise.Once the images are acquired these will be analyzed using ResearchIR software, regions of interest of the knees will then be constructed and their temperature change over the various acquisitions and how it changes after physical exertion will then be analyzed.

What researchers measure

Primary outcomes

  1. Total knee temperature

    By thermographic analysis, the average skin temperature of the entire knee will be assessed, as well as the minimum temperature and maximum temperature.

    Time frame: baseline

  2. Temperature of the knee regions of interest

    The mean skin temperature will be assessed, as well as the minimum and maximum temperature of the regions of interest in the knee, divided into medial, lateral, patellar and supra patellar areas.

    Time frame: baseline

  3. The Tegner Activity Level Scale

    The Tegner Activity Level Scale: allows the estimation of a subject's motor activity level with a score between 0 and 10, where 0 represents 'inability' and 10 represents 'participation in competitive sports, such as soccer at the national or international level. This score is the one most commonly used to define the motor activity level of patients with knee disorders.

    Time frame: baseline

  4. IKDC-Subjective Score (Subjective International Knee Documentation Committee)

    The IKDC-Subjective Score (Subjective International Knee Documentation Committee) is a subjective, knee-specific rating scale.The questionnaire examines 3 categories: symptoms, sports activity, and knee function. The response "Unable to perform any of the above activities due to knee pain" receives a score of 0 while the response "Very strenuous activities like jumping or pivoting as in basketball or soccer" receives a score of 4. This is how item 1, which is related to the highest level of activity without significant pain, is scored. For item 2, which asks about the frequency of pain in the last four weeks, the responses "Constant" and "Never" receive scores of 0 and 10, respectively. The IKDC Subjective Knee Evaluation Form is graded by adding the results of each item's scores, and then converting the result to a scale from 0 to 100.If there is a score of 100, it means that there is no restrictions on the daily activities or athletic endeavors and doesn't experience any symptoms.

    Time frame: baseline

  5. Objective parameters - Circumferences

    Bilateral trans- and supra- patellar circumferences measurement for comparative analysis.The measurement will be taken by the orthopedist by meter and will be reported in centimeters

    Time frame: baseline

  6. Objective parameters- Range of Motion

    Evaluation of the Range of Motion for comparative analysis. Range of motion (ROM) is a term used to describe how far you can move a joint or muscle in various directions. It is used to measure how much you can move a joint on your own (active ROM) or with the assistance of someone else (passive ROM).Range of motion is measured using a goniometer.
