- Registration Number
- NCT06003413
- Lead Sponsor
- Bezmialem Vakif University
- Brief Summary
The goal of this cross-sectional study is to evaluate muscle architecture changes and it's effect on muscle strength in female patients with gonarthrosis.Main questions are:
* Is there any correlation between muscle strength and muscle thickness, pennation angle fiber length?
* Is there any muscle architecture difference in gonarthrosis and is it effecting the muscle strength? The investigators will enroll patients with unilateral gonarthrosis so that investigators can compare the changes within osteoarthritic and healthy knee with the same physical activity levels.
- Detailed Description
Knee osteoarthritis (OA) is a chronic disease characterized by morning stiffness, reduced joint range of motion, chronic pain, and decreased muscle strength, leading to functional limitations as the disease progresses . In patients with knee osteoarthritis, all muscles of the hip, knee, and ankle are affected in some way . Evidence suggests that impairments in muscle strength in the lower extremities contribute to increased pain and joint space narrowing. Voluntary muscle contractions lead to various changes in muscle architecture, including changes in fascicle angle and pennation angle as well as muscle thickness. While muscle cross-sectional area and thickness are primarily associated with the magnitude of generated force, parameters such as pennation angle have been found to be more related to explosive force. Ultrasonography (US) is a non-invasive imaging method that can visualize these changes. Muscle architecture parameters obtained from US can provide reliable data related to muscle contractility independently of surrounding muscles. Furthermore, US is considered to have similar validity to MRI imaging, which is the gold standard for displaying muscle architecture. Additionally, isometric muscle strength can be reliably measured using handheld dynamometers. Although studies have investigated the relationship between muscle strength and muscle architecture determined by US in patients with knee OA, these studies have predominantly examined the relationship in the quadriceps muscle, and muscles associated with the ankle have not been studied extensively.

- Primary Outcome Measures
Name Time Method Numeric Rating Scale 1 day Self reported pain scored between 0 (minimum)-10 (maximum). Higher scores represent a worse outcome.
Outcome Measures in Rheumatology (OMERACT) ultrasound scores for knee osteoarthritis (OA) 1 day The US scores for 7 disease manifestations were then graded by the same operator using the OMERACT knee US OA atlas: semiquantitative scores for (1) synovitis (0-3; combined synovial hypertrophy and effusion); (2) binary scores (0-1) for synovial hypertrophy ≥ 4 mm, (3) effusion ≥ 4 mm12; and (4) Power Doppler (PD) signals separate from suprapatellar recess in a longitudinal plane, medial and lateral parapatellar recesses in a transverse plane, semiquantitative scores for (5) osteophytes (0-3) from the medial and lateral joint aspects in a longitudinal plane and (6) meniscal extrusion (0-2; only the medial joint aspects) in a longitudinal plane, and for (7) cartilage abnormalities (0-3) in a transverse plane on a maximally flexed knee
Health Assessment Questionnaire (HAQ) 1 day The Health assessment questionnaire (HAQ) is a questionnaire for the assessment of disability in an individual. The patients report the amount of difficulty they have in performing eight daily living activities. Each question asks on a scale ranging from 0 to 3 if the categories can be performed without any difficulty (scale 0) up to cannot be done at all (scale 3). The final score varies between 0 and 3.
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) 1 day The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was created to assess pain, stiffness, and physical function in patients with hip and / or knee osteoarthritis (OA).
The WOMAC consists of 24 items divided into 3 subscales:
* Pain (5 items):
* Stiffness (2 items):
* Physical Function (17 items) Number of items in scale: 24 items The WOMAC is available in 5-point Likert-type and 100mm Visual Analog formatsIsometric Ankle Dorsiflexion Muscle Strength 1 day Isometric Ankle Dorsiflexion Muscle Strength will be calculated with hand-held dynamometer(Lafayette Manual Muscle Tester ) and reported as kilograms.
Isometric Ankle Plantar Flexion Muscle Strength 1 day Isometric Ankle Plantar Flexion Muscle Strength will be calculated with hand-held dynamometer(Lafayette Manual Muscle Tester ) and reported as kilograms.
Isometric Knee Extension Muscle Strength 1 day Isometric Knee Extension Muscle Strength will be calculated with hand-held dynamometer(Lafayette Manual Muscle Tester ) and reported as kilograms.
