The knee carries the full weight of your body and any additional pressure from running or jumping. As such, this part of the leg is susceptible to injuries. Symptoms of knee pain may vary depending on the location of the injury. For instance, you can hurt your knee bones, muscles, ligaments, tendons or cartilage. You can also get a knee pain from degenerative tissue disorders due to aging. Before you visit a physiotherapy clinic for knee treatment, you may want to know the common causes of knee pain.
Injury to ligaments
The anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL) are the three main ligaments in the knee. Sudden injury to the knee may damage any of the above ligaments, causing severe knee pain.
Injury to tendons
Excessive use of the tendons in the knee may result in tendinitis. Common symptoms include pain in the frontal part of the knee joint, especially when walking uphill and taking stairs. Athletes are susceptible to this type of knee injury.
Repetitive knee movements can cause inflammation in the bursae, a condition clinically known as bursitis. This is one of the common causes of knee pain among those who often participate in kneeling activities, such as, military training, carpet layering and playing football.
Injury to the cartilage
The rubbery tissues and cartilage called the meniscus sits between the shinbone and the thighbone and works as a shock absorber. A sudden twisting motion of the knee, for instance, while being roughly tackled in football, may tear apart the cartilage, causing severe knee pain and inflammation.
The knee bones can be fractured from a car accident or any sudden forceful collision. This type of injury requires immediate medical attention and often requires surgical treatment.
Knee pain can also be caused by osteoarthritis, rheumatoid arthritis or any other degenerative tissue disorders. Your doctor may recommend you X-ray or other tests for a proper diagnosis.
