What Causes Sudden Knee Pain Without Injury: Exploring the Possible Culprits

Knee pain is often associated with injuries, such as sprains, strains, or tears in the ligaments and tendons surrounding the joint. However, there are instances when knee pain emerges suddenly without any apparent injury. Understanding the potential causes behind sudden knee pain is crucial for proper diagnosis and effective treatment. In this article, we will delve into some common factors that can contribute to knee pain without injury.

1. Osteoarthritis: Often referred to as wear-and-tear arthritis, osteoarthritis can gradually damage the knee joint over time. However, it can also cause sudden pain if the joint becomes inflamed.

2. Rheumatoid arthritis: An autoimmune disease that can affect multiple joints, including the knees, rheumatoid arthritis can cause sudden flares of pain and inflammation.

3. Gout: A form of arthritis caused the buildup of uric acid crystals in the joints, gout can lead to sudden and severe knee pain, commonly known as a gout attack.
