Pain
With a minor injury, you may not feel a lot of pain. However, your knee joints may feel very sore and painful. You may have trouble standing, walking or even putting any form of pressure on the hurting leg. The pain ranges from mild to severe and may require immediate medical attention.
Trouble Walking
Due to the inability to put any form of pressure on the knee, walking may be difficult or even impossible. In some cases, the knee joint feels looser than it normally should.
Feeling like the knee is ‘giving out’
During certain normal activities like walking, training or moving up and down a staircase, there might be noticeable instability in the knee, to the extent that you need to lean on the other knee for support.
