A labral injury is generally referred to as a hip labral injury. The main differences between hip synovitis and hip labral injury are etiology, symptoms, and location of damage. 1. Etiology: Hip synovitis may be caused by inflammation of the synovium of the hip joint due to trauma, pathogen infection, gout and other factors. In addition to trauma, damage to the labrum of the hip joint may be due to hip dysplasia, chronic strain, degenerative disease and other factors that cause loss of the labrum, which can easily affect the inflammatory reaction caused by the surrounding articular cartilage. 2. Symptoms: patients with hip synovitis may have pain and swelling in the hip, which will be obvious when pressed, leading to limitation of the patient’s hip joint activities, and radiating pain in the inner thigh and other parts of some patients. In addition to the symptoms of joint pain and limitation of activities, patients with labral injury of hip joint will also have the symptom of joint popping because the damaged labrum is easy to rub against the articular cartilage. 3. Damaged location: Hip synovitis is mainly due to the damage of the connective tissue of the inner wall of the joint capsule. Damage to the labrum in the hip refers to damage to the fibrocartilage tissue attached to the acetabulum. Hip synovitis and hip labral injury should go to the hospital in time for relevant examination and standardized treatment under the guidance of the doctor.
