Common Causes of a Swollen Knee

Understanding the common causes of a swollen knee is the first step in effectively addressing the issue. A swollen knee can arise from a variety of factors, broadly categorized into injuries, overuse, and underlying medical conditions. Identifying the root cause is essential for determining the most appropriate course of treatment and preventing future occurrences. Injuries are a frequent culprit behind knee swelling. Acute injuries, such as those sustained during sports or accidents, can lead to immediate swelling. Ligament injuries, such as tears in the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), or lateral collateral ligament (LCL), are common causes of swelling. These ligaments provide stability to the knee joint, and when they are injured, the body's natural response is to increase fluid production, leading to swelling. Meniscal tears, which involve damage to the cartilage that cushions the knee joint, can also result in swelling. These tears often occur during twisting or pivoting movements and can cause pain, stiffness, and a sensation of the knee locking up. Tendon injuries, including strains or tears of the tendons around the knee, such as the patellar tendon or quadriceps tendon, can also contribute to swelling. These injuries often result from overuse or sudden forceful movements. Overuse is another significant factor in knee swelling. Repetitive activities or prolonged pressure on the knee joint can lead to inflammation and fluid buildup. Bursitis, an inflammation of the bursae (fluid-filled sacs that cushion the joints), is a common overuse injury that can cause knee swelling. Patellofemoral pain syndrome, often called
