PFPS is a painful condition affecting the knee that will affect 25% of people at some point in their lives. It’s even more common in runners, hence being known as runner’s knee. The pain is felt behind the kneecap (patella) because of damage to or irritation of the articular cartilage where the patella meets the thigh bone (femur).
PFPS is considered to be an overuse injury caused by the irregular movement and rubbing of the kneecap over the thigh bone, while the knee is bending and straightening. It is the repetitive bending and straightening of the knees that makes this condition more prevalent in runners.
Specifically speaking, instead of gliding smoothly through a groove (called the trochlea) at the femur, poor knee alignment causes the kneecap to mistrack and instead rub against the thigh bone itself. This causes irritation at the joint and damage to the underlying cartilage and bone. Other causes can include:
Aside from running, PFPS typically is particularly prevalent in basketball, football, volleyball, netball, skiing and other running/jumping sports.
Symptoms tend to come on gradually during high-impact activities such as running, squatting and climbing stairs. It can then continue during low-impact activities like walking and for some, may even be felt during rest. Symptoms include:
To reduce the painful symptoms, the PRICE principles (protection, rest, ice, compression, elevation) will help. Treating PFPS involves addressing the specific cause(s) and correcting any alignment issues that may cause the pain to recur in the future. This often involves:
It is very important to not delay treating PFPS to avoid further damage to the knee joint and the articular cartilage. Because articular cartilage works to protect the bone ends and help them glide smoothly against each other, the more it is damaged, the higher the likelihood for further knee pain and problems.
Two weeks with Calcaneal Spur and finally got to see Doc. He sent me to Kevin @ Eleven and with One Appointment, he had me walking without Crutches. Yes! It still hurt. Did the Stretching, Rolling my Foot on a Spikey ball and Iced it occasionally. Return visit, after he had his Holiday, and I' am walking fine. They do NOT want to see me again, unless it deteriorates. Which it has not :-)
