This is the deep pain felt in the middle of the joint and it is often hard to localise. It usually occurs after trauma such as a sprained ankle or impact injury. There is usually swelling and can feel sharp and catching in the joint. These can be missed with the initial pain of a sprained ankle but can be the reason it doesn’t ever quite get better.
The problem is that the cartilage has been knocked off of the end of the bone. This is a distinct local trauma as opposed to the more generalised arthritic change. Although it can lead onto arthritis.
Treatment depends on the severity. We work with our surgical colleagues to get the full diagnosis and treatment plan but they need to be treated properly or they lead to long term issues. If in doubt get it seen!
