• Snapping, grinding, or popping sensations or sound coming from the joint when you attempt to move it.
• Coldness, tingling, or numbness in the joint.
• Bruising or swelling.
• Color changes around the knee, such as paler skin or shades of blue or red.
• Weakness or instability in the joint. A feeling that your knee will not hold you up.
