Is subchondroplasty suitable for knee pain from a bone marrow lesion?

I haven't heard of many people in Singapore going for that procedure, so it's quite a specialist thing. Since your doctor has already flagged it as an option for you, I'd say it's worth asking him more detailed questions about whether it's the right fit for your specific case, what the recovery timeline looks like, and if there are other options to consider first. Bone stuff can be tricky, so getting a second opinion from another ortho or sports medicine doctor might help you feel more confident about which direction to go, especially since you've been dealing with this pain for a while already.
