A loose knee [เข่า หลวม, which means in thai]. is an intervertebral disc related medical condition characterized by clicking and popping sounds, agonizing pain, and a sense of instability in the joint. The condition is often caused by some traumatic injury, including a sudden twisting, which usually results to the snapping of the kneecap or tearing of the ligaments that hold the kneecap to the shinbone. This is one of the most common sports injuries that people experience and can be a source of much discomfort and agony for the patient. In addition, this condition is also associated with a variety of other symptoms such as pain, swelling, clicking and popping, and even a pinching sensation. However, not many people are aware that they may suffer from this condition until it is already too late and the symptoms have already manifested. If you are experiencing any of these symptoms, then it would be best if you consult your doctor for proper diagnosis and possible treatment for the condition. One of the many symptoms of this condition that you should watch out for is a constant excruciating pain in the joints, especially when you move your knees. The pain may be accompanied by swelling, clicking and popping sound when the knees are bent. Also, the patient will experience a great amount of discomfort when he kneecaps are touched. Some patients who have suffered from this disorder also complain of swelling, tightness, and numbness of their knee joints. Others also complain of pain and stiffness when they try to bend their knees. If you are experiencing any of these symptoms, then it would be best if you visit your doctor immediately so that you can seek immediate treatment for the problem. When the condition is diagnosed through a medical examination, then a diagnosis of a posterior cruciate ligament tear is made. With the help of X-rays and CT scan, a diagnosis is given but still no precise way to determine the exact knee feels loose. Your doctor may just recommend simple exercises for treating the pain and preventing the further damage of the structure. This is called the conservative approach. Most doctors prefer a combination of non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy for treating this condition.
