Rehabilitation exercises for synovitis of the thigh root include self-functional exercises, such as non-weight-bearing hip flexion and extension exercises and straight leg raising exercises, as well as physical rehabilitation exercises. Hip flexion and extension activities as well as abduction and adduction activities can be carried out in normal times, with attention paid to the need to avoid weight-bearing and stress on the hip joint, etc. In addition, straight-leg raising functional exercises can be carried out, which can strengthen the muscle strength of the lower limbs and avoid contractures and adhesions in the joints, which can help to maintain the stability and coordination of the thigh-root, i.e., the hip joint, etc. Physical rehabilitation exercises can also be carried out.
