Discomfort in the knee can signal strain, irritation, or damage in one or more structures that support the joint. It's not a condition in itself, but rather a symptom of an underlying issue that needs attention.
The knee is one of the most stressed and relied‒upon articulations in the human body. It absorbs shock, supports all the weight, and allows for a wide range of motion—making it especially vulnerable to wear, injury, or imbalance.
Its stability relies on four main ligaments, surrounding muscles, and joint structures. When any part of these components is injured or weakened—due to overuse, trauma, or underlying conditions—pain can emerge.
