According to the surgeon, the damage was not all the way to the bone
and is located underneath the knee
cap. He said that I do not need surgery
and just need to wait for it to go away.
It's been two months since the injury. The pain has gotten less indeed. However, after reading articles about articular cartilage, I understand that articular cartilage has limited ability for healing, escpecially if its not all the way to the bone (Grade 4).
