Patient : Last week my friend sat on my knee and I felt a stretch and now there is a bruise on the inner side of my knee and it feels like the bruise goes onto the back side of the knee. Also my whole knee is bruising and there is some bruises under the knee on the lag and above the knee on the theigh. I have patellar Tendonitis so I dont know if that makes it worse. Do you know what is wrong?
