How long the hip cartilage wear can be recovered is related to the size and depth of the patient’s injury area, severity, treatment and other factors. Mild cartilage wear can be recovered in 4 to 6 weeks, while severe wear cannot be recovered in general. 1. Mild: chondroitin sulfate can be given to promote cartilage repair, and at the same time, attention should be paid to the protection of the hip joint, avoiding frequent squatting, or too much climbing, climbing and other sports, so as to reduce the wear and tear of the articular cartilage, which is conducive to the repair of the cartilage. For patients with simple muscle strains and ligament strains, the time for soft tissue damage repair is 4 to 6 weeks. 2. Severe: Conservative treatment often can not be restored, arthroscopic surgery can restore the position of hip cartilage wear and tear flat, but also can not be completely restored cartilage. When the cartilage of the hip joint is worn out, it is necessary to improve the relevant examinations under the guidance of the doctor, such as magnetic resonance, arthroscopy, etc., to confirm the degree of cartilage wear and give standardized treatment.
