Status Recruiting

Clinical Trial 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.

Clinical Trial 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. ;
