What is a subchondral edamatous contusion? is it a bone bruise? how to heal it? does it need physiotherapy?

Bone bruise: It will heal within 6 weeks, no surgery. Just time & gentle exercises.

Bone bruise : Bone bruise below the cartilage. Low intensity, low impact cardiovascular exercise, gentle range of motion and ice. Never apply ice directly to the skin, always over a towel or clothing. Repeat 2-4 times per day. Consider physical therapy if symptoms persist beyond 6-8 weeks.
