Synovitis of the hip joint in adults usually recovers gradually in 3-4 weeks after regular treatment. Synovitis of the hip joint is an aseptic inflammation of the hip joint caused by trauma and excessive exercise, which mainly manifests as persistent pain and limited movement of the hip joint. After the diagnosis is confirmed, patients should rest in bed, avoid the hip joint from getting cold and avoid overexertion. Patients with mild pain can take oral or topical NSAIDs, such as ibuprofen, celecoxib, fotarine ointment, or take blood-activating and blood-stasis-removing Chinese medicines. Patients with severe pain can inject sodium glutamate, glucocorticoids and other drugs into the joint cavity to relieve pain. After 3-4 weeks of conservative treatment, the symptoms can be relieved. Severe cases of hip synovitis can also be treated with surgery. Early detection and regular treatment of hip synovitis can lead to a cure.
