Ask Dr Alan Cheung: Sport Injuries & ACL Tears

Sorry to hear about your knee and the symptoms you are experiencing. In general a PCL does not need surgical treatment and most people can do quite well without it. Your instability symptoms may be due to a new problem in the knee (if you have had another injury), such as a meniscal tear, or from weakness in the muscles stabilising the knee. It sounds like you need to get you knee reviewed. I would suggest either going back to your original surgeon/physician or you could see a Sports Physician/Sports Physiotherapist for further assessment. They may rescan your knee as part of this assessment.

Thank you for your question. I'm not exactly sure what you are referring to when you mention a huge dent in the nose. As you rightly pointed out, one of the common causes for depressions in the nose is from traumatic injury to the nasal bone. If you are sure that there is no previous trauma to the nose, the other possibility is acne scars. Depending on the severity this can be treated with CO2 lasers, fillers or fat grafts.

Dental trauma is a very big topic and it covers quite a lot of things. The trauma that you can sustain to your teeth can be very simple or it can be very complicated. For example, you could have a small chip on your front tooth, that’s considered a traumatic injury to your tooth. It can be just a small little chip and might not even cause pain, but it can still be considered to be trauma. On the other spectrum, you could have trauma to your teeth as a result of a very serious accident, for example, road traffic accident.

A quick blood test can be for gout, which comes and goes. Maybe there is an existing problem. Keep a journal on these kinds of pain, the timing when it happens, and what you are doing at that time, every time you do something to trigger the pain. If it keeps coming back then we can do a quick blood test.

I’m sorry to hear about your pain symptoms. There can be many different causes for hip pain ranging from degenerative changes, hip flexor tightness, gluteus medius tendonopathy, hip impingement or a labral tear. The position you are putting your hip into is similar to the Fabers test position and could be suggestive of a labral injury - quite why you have developed this without any trauma needs further evaluation. You would probably benefit from an assessment if the symptoms are ongoing - you could see a MSK/Sports Phsycian or physiotherapist who can take a history and examine you.
