Whether or not the chondromalacia patella will heal on its own needs to be determined by the extent of the injury. Mild injuries without ligament damage may heal on their own. However, severe injuries cannot heal on their own. If the degree of injury is mild and there is no accompanying ligament damage, and the patient is able to stop exercising, rest in bed, and reduce weight bearing on the knee joint, the chondromalacia patella may heal on its own. If the degree of damage to the patellar cartilage is more serious, or accompanied by ligament damage, resulting in chondromalacia patella or other symptoms, and do not timely symptomatic treatment, it will lead to further aggravation of patellar cartilage damage, may also lead to patellar cartilage localized ischemia and necrosis, and can not be cured by itself. The correct approach is that the patient should take bed rest, infrared irradiation and other physical therapy methods in the knee joint, and if necessary, surgical treatment, such as cartilage repair. Patients with damage to the patellar cartilage are advised to go to the hospital for treatment in time, do not be careless, and take the next step under the guidance of the doctor.
