Got kicked really hard in the knee during a soccer game. I fell to the ground and felt a tingling sensation but I finished the rest of the game. I looked at my knee afterwards and it was extremely swollen and starting to bruise purple. It s been about a week and I am walking with one crutch and in a ton of pain. The brusing has spread and is yellow red and purple. It isn t as swollen, but still puffy and hard. It doesn t hurt so much where I was in kicked, but it hurts inside. I cannot completely straighten or bend my knee. It feels unstable and it is stiff.
Hi there, thanks for your question at Chat Doctor. Inability to fully straighten your knee at the end of one week, suggests injury structure called meniscus. Meniscus is a disc like structure present between the knee joint responsible for soft gliding during movements. It is responsible for full range of gliding movements tithe knee joint. Inability to straighten suggests that part of this meniscus is then and his feet caught between the gliding bone surfaces.  The color changes in the bruise are natural healing process of a bruise. Also pain on walking can mean injury to other structures or a bruise on the bone also. The stiffness. Can also be due to blood collection in the joint. I would suggest you to meet a sport medicine doctor. He/ she will be able to advice you about further action, which might include in MRI for confirmation. Hope this helps. All the best. Regards.  Chat Doctor.
