Some of the most commonly experienced knee injury symptoms include swelling, painful sensations around the knee, popping sounds, difficulty in lifting loads, problems bending, bruising, locking of the knee and tenderness, as noted by MedicineNet. There are several types of knee injuries, with the most common being knee fractures, sprains, strains, bursitis and knee joint dislocation. Knee complications are quite common and can affect anyone regardless of age and gender, according to the National Institute of Arthritis and Musculoskeletal and Skin Disease.
Knee injuries can be caused by a number of causes including sporting activities, car accidents and falls. Other knee complications may be brought about by conditions such as arthritis, got, kneeling for too long or infections.
The most clear indication of knee injury is experiencing pain and swelling around the knee. Other indicators include having difficulty in moving or bending the affected knee and redness of the area affected. Doctors may have to carry out physical tests, an X-ray and history examination in order to determine whether a person has an injured knee or something else.
Mild knee injuries are basically treated by resting, applying ice, compressing the affected area and elevation. Immobilizing the knees may also help speed up the process of healing. Severe cases of knee injury are treated by the use of anti-inflammatory medications and surgery in certain cases.
