Osteoarthritis refers to the degeneration of weight-bearing joints, particularly the hips and knees. It is commonly seen in individuals aged 45–60 years and older. Among Thai people, knee osteoarthritis is the most prevalent. It may begin with stiffness and difficulty standing up, eventually progressing to deformities of the knee joints, such as bowlegs or knock-knees.

This disease can significantly affect daily life. Its progression may start with mild symptoms, such as stiffness, and escalate to severe pain that interferes with everyday activities. If left untreated, symptoms can worsen over time, leading to a decline in both quality of life and the ability to perform daily tasks.
