Arthritis. Subchondral cysts occur in arthritis. Fai predisposes you to arthritis of the hip, especially anteriorly. Accident usually doesn't cause arthritis so quickly.
It's. It's difficult to be sure how your particular condition developed. Fai is associated with cartilage damage, labral tears, early hip arthritis, hyperlaxity, sports hernias, and low back pain. Fai is common in athletes, but also occurs in active individuals. Since you've been diagnosed, you're likely aware of your treatment options. I would make sure that your orthopedic doctor has experience in treating fai. Good luck!
