Ultrasonography-based measurements of femoral cartilage thickness
Tidsramme: Day 1
|
During femoral cartilage thickness measurements, participants will be positioned in the supine position, and the knee will be brought to maximum flexion for evaluation through the suprapatellar window.
The probe will be positioned in the transverse plane, and measurements will be taken at the level of the medial and lateral femoral condyles and the intercondylar groove.
For standardization, each measurement will be repeated three times, and the average will be recorded.
Cartilage thickness will be defined as the distance between the hypoechoic cartilage layer and the subchondral bone surface.
Lower values indicate that osteoarthritis has caused more structural damage.

Western Ontario og McMaster Universities (WOMAC) score
Tidsramme: Dag 1
|
WOMAC Osteoarthritis Index-spørgeskemaet, som består af 5 spørgsmål ved brug af en Likert-skala, er tilgængeligt i den vedlagte case report form for at vurdere smerter, stivhed og funktioner i dagligdagen.
WOMAC Osteoarthritis Index indeholder 24 spørgsmål, der dækker tre subskalaer: smerter (5 spørgsmål), stivhed (2 spørgsmål) og funktion (17 spørgsmål). Scoringssystemet består af WOMAC smerte-score, WOMAC stivhed-score, WOMAC funktions-score og WOMAC total-score. Der er udført et tyrkisk validitets- og pålidelighedsstudie. |

Visuel analog skala
Tidsramme: Dag 1
|
Visual analog skala måler smerte, som den opleves subjektivt.
Den bruger en 0-10 cm skala, det mest almindeligt anvendte værktøj til kvantitativ bestemmelse af smerteintensitet, hvor den ene ende repræsenterer ingen smerte og den anden ende repræsenterer den mest intense smerte muligt.
'0' angiver ingen smerte, mens '10' angiver den mest intense smerte.
Den enkelte bliver bedt om at vælge den numeriske værdi, der bedst repræsenterer deres tilstand.
Denne markerede værdi bruges som numerisk data til at bestemme niveauet for smerteopfattelse.
En højere score indikerer et højere smerte niveau.

Måling af bevægelighed i led
Tidsramme: Dag 1
|
Knæfleksion og -ekstension måles bilateral ved anvendelse af universel goniometri for at vurdere patienters ledbevægelighed, og vinklerne registreres.

Kellgren-Lawrence-klassifikation
Tidsramme: Dag 1
|
Kellgren og Lawrence-systemet er en bredt anvendt metode, der klassificerer sværhedsgraden af knæartrose i fem grader.

Dag 1

Assessment of osteophytes via ultrasonography
Tidsramme: Day 1
|
During osteophyte assessment, participants will be positioned in the supine position with the knee flexed approximately 30 degrees; the probe will be placed along the medial and lateral joint lines in the longitudinal and transverse planes to examine bony projections.
Osteophytes will be scored according to the Outcome Measures in Rheumatology knee osteoarthritis scale criteria as small (<2 mm - Grade 1), moderate (2-4 mm - Grade 2), and large (>4 mm - Grade 3).

Day 1
|
|
Assessment of synovial hypertrophy via ultrasonography
Tidsramme: Day 1
|
In the ultrasound assessment of synovial hypertrophy, the thickness of hypoechoic tissue in the suprapatellar region that does not shift upon probe compression will be measured, and values exceeding 2 mm will be recorded as synovial hypertrophy.
|
Day 1
|
|
Assessment of synovial effusion via ultrasonography
Tidsramme: Day 1
|
Ultrasonographic assessment of joint effusion will be performed at the suprapatellar recess level; participants will be positioned in the supine position with the knee in near-extension or slight flexion.
During the longitudinal plane examination, anechoic fluid collections will be measured, and values of 4 mm or greater will be considered pathological synovial effusions.
|
Day 1
|
|
Assessment of meniscal protrusions via ultrasonography
Tidsramme: Day 1
|
During the ultrasound assessment of meniscus protrusion, the knee will be positioned with approximately 30 degrees of flexion, and the extent to which the meniscus tissue extends beyond the tibial margin will be evaluated in measurements taken in the longitudinal plane along the medial joint line; protrusions exceeding 3 mm will be considered pathological meniscus protrusions.

Day 1

Ultrasonography-based measurements of quadriceps muscle thickness
Tidsramme: Day 1
|
For ultrasonographic measurements of quadriceps muscle thickness, participants will be positioned in the supine position with the knee extended and the muscles fully relaxed; measurements taken in the transverse plane at the midpoint between the anterior superior iliac spine and the superior pole of the patella will assess the thicknesses of the rectus femoris and vastus intermedius muscles together.
|
Day 1
|
|
Ultrasonography-based measurements of quadriceps tendon thickness
Tidsramme: Day 1
|
Ultrasonographic measurements of the quadriceps tendon will be taken in the longitudinal plane immediately proximal to the superior pole of the patella while the knee is flexed to approximately 30 degrees, and the average of the measurements taken 5, 10, and 15 mm proximal to this point will be recorded
|
Day 1
|
|
Ultrasonography-based measurements of patellar tendon thickness
Tidsramme: Day 1
|
Ultrasonographic assessment of the patellar tendon is performed with the knee flexed to 30 degrees, in the longitudinal plane from the apex of the patella distally, and the anteroposterior thickness is measured approximately 5 mm distal to the apex.

Ultrasonography-based measurements of pre-tibial and thigh subcutaneous thickness
Tidsramme: Day 1
|
The diagnosis of lipedema will be supported by ultrasonographic measurements of subcutaneous fat thickness in the thigh and pretibial regions.
With the patient in the supine position and the lower extremities relaxed and in a neutral position, the probe is placed in the transverse plane (anterior surface of the tibia), at the midpoint between the tibial tuberosity and the medial malleolus, and on the thigh, at the midpoint along the midline between the iliac crest and the lower edge of the patella, and the total thickness of the skin and subcutaneous tissue will be measured in millimeters by applying minimal pressure.
Each measurement will be taken three times, and the average will be calculated.
In the literature, diagnostic threshold values have been established as a thickness measurement of >11.7 mm in the pre-tibial region and >17.9 mm in the thigh.
