Evaluation of Meniscal Extrusion by Dynamic Ultrasonography in Patients With Ostearthritis

Not Applicable

Completed

• Conditions: Meniscus Disorder; Knee Osteoarthritis
• Interventions: Diagnostic Test: Ultrasonographic evaluation

• Registration Number: NCT06113536
• Lead Sponsor: Istituto Ortopedico Rizzoli

Brief Summary

This is a diagnostic, open-label, single-center interventional study. The aim of the study is to evaluate the relationship between medial and lateral meniscus extrusion determined by dynamic ultrasound study and bone edema assessed by MRI study in patients with knee OA.

As a secondary objective, the correlation of the above parameters with the patient's symptomatology assessed by subject clinical questionnaires will be evaluated.

Detailed Description

Patients with a diagnosis of knee OA will be included in a study involving evaluation of the correlation between meniscal extrusion assessed by dynamic ultrasonography and bone edema assessed on MRI. A total of 202 patients will be included, who, after providing their signed informed consent to participate in the study, will undergo dynamic ultrasonography. After giving signed consent to participate in the study, the patient will undergo the following examinations::

* ultrasound evaluation for assessment of possible meniscal extrusion;

* At the same time as the ultrasound examination, subjective questionnaires will be administered to patients.Recent radiological examinations of the patients or from the patient's medical record will be collected during or before the diagnostic investigation.

Arm && Interventions

Group	Intervention	Description
Ultrasonographic evaluation	Ultrasonographic evaluation	Ultrasonographic evaluation for assessment of possible meniscal extrusion

Primary Outcome Measures

Name	Time	Method
Meniscal extrusion	baseline	Meniscal extrusion in clinostatism and orthostatism, assessed in millimeters (mm) or percent meniscal extrusion relative to tibial margin, and difference between the two measurements

Secondary Outcome Measures

Name	Time	Method
Tegner Activity Level Scale	baseline	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.
EQ-VAS	baseline	Visual analog scale consisting of a straight line segment (10 cm length), the ends of which correspond to "no pain" and "the strongest pain imaginable."
IKDC-Subjective Score (Subjective International Knee Documentation Committee)	baseline	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
VAS-dolore (Visual Analogue Scale)	baseline	Visual analog scale consisting of a straight line segment (10 cm length), the ends of which correspond to "no pain" and "the strongest pain imaginable."
KOOS Score ( Knee Injury and Osteoarthritis Outcome score)	baseline	The full questionnaire consists of five subscales and they cover: pain (9 items), symptoms (7 items of which two relate to stiffness), functions and activities of daily living (17 items) physical function, sports activities and leisure (5 items) and quality of life in relation to the knee (4 items). All items in the relevant subscales have the same response mode, use a 5-point Likert scale, and each question is assigned a score from 0 to 4, where 0 indicates "no difficulty" and 4 "a severe difficulty). Score range 0-100 for each subscale
Objective parameters - Circumferences	baseline	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
Objective parameters- Range of Motion	baseline	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.
