Patients with hip synovitis should keep their lower limbs in a straight position, not in a flexed half booth, otherwise it will easily cause contracture of the hip capsule and surrounding muscles. Patients with hip synovitis generally like to put their lower limbs to one side when they sleep and bend their legs up so that the hip joint is in a flexion-external rotation position, and this posture feels comfortable for a certain reason, because the hip joint internal pressure is low. However, this posture is likely to make the hip capsule and surrounding muscles in a long-term relaxed state, causing contracture, which will form a certain deformity over time and affect future walking. Hip synovitis treatment suggestions are as follows: 1, do physical therapy for the muscles around the hip joint to treat congestion, edema and inflammation around the hip joint, which is conducive to the absorption of synovial fluid in the hip joint and the remission of inflammation; 2, rehabilitation exercises, with the help of doctors or the patient’s family members to do functional exercises and muscle massage for lower limbs abduction and posterior extension, which is conducive to the functional rehabilitation of the hip joint.
