The exact recovery time for patellofemoral arthritis is not fixed and varies according to the severity, usually taking 2 weeks to 2 months, and severe arthritis may be associated with a lifetime. Patellofemoral arthritis evolves due to poor joint alignment, wear and tear of articular cartilage, and narrowing of the joint space as a result of trauma, developmental abnormalities, and joint degeneration. There is no specific time for the treatment of patellofemoral arthritis, depending on the severity, the treatment time time is different, if the symptoms are relatively mild, it can be significantly relieved in about 2 weeks; if the knee pain is more pronounced, the patellofemoral arthritis is heavier may take about 2 months. If the wear and tear of the patellofemoral joint is heavier and patellofemoral arthritis is more serious, it may not be able to heal by itself, or even accompanied by lifelong, and need to be completely treated by surgery, such as artificial joint replacement. If symptoms such as knee pain and discomfort persist without relief, it is recommended to consult a doctor in time, complete the relevant examinations and follow the doctor’s instructions for treatment.
