<s>[INST] I am a 19 year old female. I dislocated my patella 5 years ago and have had 5 surgeries. I have been through countless times of physical therapy tried all types of braces had injections and also tried medicine. I still have severe pain with my knee and it is hard to complete daily activities. [/INST] Hi, There seems to be a cartilage injury present at the time of dislocation which over time will lead to patellofemoral joint arthritis. A cartigram proves to be diagnostic, MRI can be used also. Only after the confirmation of diagnosis and its extent, we can choose between conservative management such as intra-articular hyaluronic acid inj to surgical management such as arthroscopic debridement to joint replacement. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Rohan Shanker Tiwari, Orthopedic Surgeon </s>
