Patellofemoral syndrome is pain at the front of the knee. It is commonly found in athletes who put heavy stress on their knees, and is commonly known as runner’s knee.
Patellofemoral pain syndrome is pain behind the kneecap. It has been given many names,including patellofemoral disorder, patellar malalignment, runner’s knee, and chondromalacia.
Patellofemoral pain syndrome can occur from overuse of the knee in sports and activities such as running, walking, jumping, or bicycling. The kneecap (patella) is attached to the large group of muscles in the thigh called the quadriceps. It is also attached to the shin bone by the patellar tendon. The kneecap fits into grooves in the end of the thigh bone (femur) called the femoral condyle. With repeated bending and straightening of the knee, you can irritate the inside surface of the kneecap and cause pain.
Patellofemoral pain syndrome also may result from the way your hips, legs, knees, or feet are aligned. This alignment problem can be caused by your having wide hips or underdeveloped thigh muscles, being knockkneed, or having feet with arches that collapse when walking or running (a condition called overpronation).
The main symptom is pain behind the kneecap. You may have pain when you walk, run, or sit for a long time. The pain is generally worse when walking downhill or down stairs. Your knee may swell at times. You may feel or hear snapping, popping, or grinding in the knee.
Your health care provider will review your symptoms, examine your knee, and may order knee x-rays.
Treatment includes the following:
Place an ice pack on your knee for 20 to 30 minutes every 3 to 4 hours for the first 2 to 3 days or until the pain goes away
Your health care provider may recommend that you:
While you are recovering from your injury, you will need to change your sport or activity to one that does not make your condition worse. For example, you may need to bicycle or swim instead of run. In cases of severe patellofemoral pain syndrome, surgery may be recommended. Your health care provider will show you exercises to help decrease the pain behind your kneecap.
The goal of rehabilitation is to return you to your sport or activity as soon as is safely possible. If you return too soon you may worsen your injury, which could lead to longer healing times. Everyone recovers from injury at a different rate. Return to your sport or activity will be determined by how soon your knee recovers, not by how many days or weeks it has been since you were injured. In general, the longer you have symptoms before you start treatment, the longer it will take to getbetter.
You may safely return to your sport or activity when, starting from the top of the list and progressing to the end, each of the following is true:
Patellofemoral pain syndrome can best be prevented by strengthening your thigh muscles, particularly the inside part of this muscle group. It is also important to wear shoes that fit well and that have good arch supports.
Knowing When to Seek Care for Your Child: A Guide from LuskinOIC
As a parent, your top priority is keeping your child safe and healthy. But when your child is sick or injured, it can be hard to know what level of care they need. Should you call your pediatrician, visit urgent care, or head straight to the emergency department?
