case_images: Her left hip radiograph showed degenerative arthritis categorised as Tonnis grade 2, and bone cysts were noted on the femoral heads (Figure 2(a)). One year after the initiation of jiggling exercise, the patient's hip pain notably improved, despite the absence of changes in the hip radiographs (Figure 2(b)). Three years later, the patient's hip pain remarkably improved and the radiographs of the hip joint showed notable improvement in terms of congruity and space width (Figure 2(c)). At the last follow-up, 4 years after the indication of the jiggling exercise, radiography revealed improved joint remodelling (Figure 2(d)).

case_images: The radiograph on her left hip showed degenerative arthritis categorised as Tonnis grade 3, terminal OA (Figure 3(a)). One year after the initiation of jiggling exercise, the patient's hip pain and ROM remarkably improved, and the plain radiograph of the hip revealed some improvement of joint congruity (Figure 3(b)). The radiographs of the hip joint showed remarkable improvement of joint congruity and space width (Figure 3(c)). Furthermore, plain radiographs revealed improving joint remodelling (Figure 3(d)).
