Joint, Ligament and Tendon Conditions
Knee pain is a common reason that people visit their doctors. The knee is the largest weight-bearing joint in the body and takes significant stress when an individual walks, runs, or plays sports. The knee has obvious actions, including flexion and extension or bending and straightening. But the knee also can slide and pivot slightly. Pain with bending the knee is a sign of injury or damage within the joint.
The patella, or kneecap, is a small bone on the front of the knee joint. Patellar subluxation occurs when the tendons that stabilize the kneecap abnormally slip out of place. This condition, which is also referred to as a partial patellar dislocation, typically occurs following traumatic injury to the knee joint. People who develop patellar subluxation symptoms should contact a doctor for further evaluation and care.
Knee injuries, however minor, can cause pain and discomfort that prevents you from engaging in your normal daily activities. Knowing when to use ice and when it is okay to use heat on a knee that is in pain or injured can make a big difference between easing the pain and encouraging your knee to start healing or preventing your knee from starting the healing process, potentially causing more pain.
Your knees sustain an impact from each running stride you take. You can help keep your knees healthy by building your mileage over time and knowing when to rest. If your knees start to hurt, it's important to know what's causing your pain so you can properly treat it. Iliotibial Band syndrome, or IT band syndrome, is a common cause of outer knee pain for runners.
The kneecap, or patella, is one of three bones that compose the knee joint. Without proper care or through injury or overuse, the kneecap can become stressed or damaged, leading to pain, swelling or other problems. Although some cases of kneecap pain and swelling are manageable at home, symptoms that are severe; are accompanied by numbness, fever or tingling; or continue for more than one week require evaluation by a medical professional.
As anyone who has ever been pregnant, or has known a pregnant woman, knows quite well, pregnancy can put a great deal of stress on a woman's body. Not only does her weight increase--sometimes dramatically--but her center of gravity shifts. Further, her joints soften in preparation for delivering a baby. This is a recipe for joint pain, and knee pain is no exception.
Knee pain is a common complaint in active children who tend to suffer repeated trauma to the legs. But trauma is not the only reason for children to complain of knee pain--it can also be a symptom of a more serious condition. Prompt identification and treatment of these potentially crippling conditions is necessary to avoid long-term disability.
The space between the femur, or thighbone, and the tibia, or shinbone, on X-ray views represents the overall thickness of the joint cartilage surfaces of each opposing bone as they articulate, or come into contact with one another. As this cartilage wears down over time, and as part of the degenerative process associated with arthritis, this so-called space begins to narrow—not unlike tread on a tire. Degenerative joint disease in the knee can be treated in a variety of ways, each with their own specific goals.
Pain is common immediately after anterior cruciate ligament, or ACL, reconstruction surgery. With time and active rehabilitation, this pain should decrease and eventually disappear. There are several causes of pain that starts days to years after surgery.
Aside from the fact that walking on a treadmill is an impact sport, knee pain can be caused by a lack of spinal rotation when striding, over pronation and incline running. Also, the treadmill maintains a steady speed which impedes your body's natural tendency to adjust its pace as necessary. The forced speed of the treadmill can also cause knee pain if forcing the runner to go too fast or too slow. Without sufficient recovery, these stresses can eventually lead to irritation and inflammation to the tendons, ligaments and other tissues connected to this joint.
