Knee pain refers to any discomfort, soreness, or injury that affects the knee joint, which connects the thigh bone (femur), shin bone (tibia), and kneecap (patella). This type of pain can result from a variety of causes, including injury, overuse, or underlying health conditions. Common causes of knee pain include ligament injuries (such as ACL tears), cartilage damage (like meniscus tears), arthritis, patellar tendinitis, and bursitis. Other factors such as age, weight, or improper movement patterns during exercise or daily activities can also contribute to knee pain.
As temperatures drop during the winter months, many people experience an increase in knee pain, whether it's from old injuries or underlying conditions like arthritis. The cold weather can lead to stiffer joints, reduced blood flow, and changes in air pressure that exacerbate discomfort in the knees. For those who already have conditions like osteoarthritis, the cold can increase the sensitivity of the joint, making pain more pronounced. Additionally, people tend to be less active in winter, which can lead to muscle stiffness and weakness, further stressing the knee joints.
