Runner's Knee (Patellofemoral Stress Syndrome) |
|
The knee is subject to enormous workloads during sports activities. The muscles that surround the knee provide mobility and strength to the legs. When athletes run or jump, the kneecap (patella) alone often endures forces of 500 to 700 kg. The entire knee joint is under massive stress with these kinds of activities, especially when there are imbalances in muscle strength or flexibility. In time, overuse injuries, such as runner's knee, may develop.
Runner's knee, also known as patellofemoral stress syndrome, is a condition characterized by the kneecap rubbing against the femur (thigh bone) when moving. Nearly 30 percent of runners eventually develop runner's knee. Skiers, cyclists, soccer players, and people who participate in high-impact aerobics classes may also get runner's knee. This condition can be caused by various structural defects and running styles. These include a kneecap that is located too high in the knee joint, weak thigh muscles, tight hamstrings or Achilles tendons, pronating or running with the feet rolling in, while the thigh muscles pull the kneecap outward. The following are the most common symptoms of runner's knee. However, each individual may experience symptoms differently. Symptoms may include: - pain in and around the kneecap that may be felt with activity, or even after prolonged sitting with the knees bent, occasionally resulting in weakness or feelings of instability. The pain is most noticeable going down stairs or hills.
- rubbing, grinding, or clicking sound of the kneecap that can be heard at times when the knee is bent and straightened.
- kneecap is tender to the touch.
The symptoms of runner's knee may resemble other conditions and medical problems. Always consult your doctor for a diagnosis. Your doctor or sport's physician will determine specific treatment for runner's knee based on your age, overall health, and medical history, the extent of the injury, your tolerance for specific medications, procedures, or therapies, and your expectations for the course of the injury. The best course of treatment for runner's knee is to stop running until running can resume without pain. Other treatments include stretch and strengthening exercises and orthotic supports in shoes. Seek medical evaluation if the knee pain does not improve with rest and decreased activity. People with knee pain should try to switch to a non-weight bearing exercise like bicycling, swimming, or rowing. To avoid injury when running, never run straight down a steep hill. Walk down it. If walking downhill is out of the question, then run down in a zigzag pattern. Lean forward and keep the knees bent. This technique will reduce the risk for knee injury. Wear good quality sports shoes with proper arch supports and cushioning. Be sure to replace running shoes every 500-800km. A pair with good protective cushioning will cost at least $100 Aus.
