• • • • Introduction Pain, swelling, stiffness, or a buckling sensation in the knee can signal the presence of a wide variety of conditions or injuries that may affect the general population. But patients who injure or aggravate their patellofemoral joint, where the end of the femur (the long bone in the thigh) meets the patella (the kneecap), or those who develop arthritis in this portion of the knee only, often have specific complaints such as pain with stairs especially descending, pain with prolonged sitting, and pain going from a sitting to a standing position. They may also have anatomical features that put them at risk for their condition. Seeking prompt medical attention for injuries or disease that affect the patellofemoral joint can help assess the degree of risk present and minimize or prevent further injury. In the healthy knee, the bones that make up the patellofemoral joint move smoothly against one another as the joint is bent or extended, with the patella gliding in a groove or trochlea of the femur (the groove may also be referred to as the sulcus).

One of three compartments in the knee, together with the lateral compartment on the outside of the knee and the medial compartment on the inside, the patellofemoral joint is supported and stabilized by a complex network of ligaments, tendons and other soft tissues.

Problems affecting the patellofemoral joint most frequently include pain, instability (subluxations or dislocations of the patella - when the kneecap moves partially or fully out of the groove in the femur) and arthritis.

Patellofemoral Pain Syndrome Patellofemoral pain syndrome describes pain in the patellofemoral joint (kneecap and front part of femur) that is due to overuse rather than a traumatic injury. Although this pain may first become apparent during athletic activities such as running, it is also evident with everyday activities. Patients often notice it when going up - and especially down - stairs, after sitting for a long time, with the transition from sitting to standing, and when squatting, kneeling and lunging. Wearing high heels can also exacerbate symptoms. The pain is usually less pronounced when walking on level ground. Other names for patellofemoral pain syndrome include chondromalacia patella (a reference to the degeneration of cartilage in the kneecap) and runner’s knee or moviegoer’s knee.

According to associate attending orthopedic surgeon at HSS, on examination, the pain is often found at the lower and outer margins of the kneecap - underneath the patella and at the outside of the knee. However, patients may also experience pain more diffusely over the whole joint when there is more severe inflammation. “Patients with this syndrome have an uneven distribution of stress or load underneath the kneecap that is causing pain,” Dr. Shubin Stein explains. Sometimes, this is due to an abnormal tilt of the patella which can be seen on x-ray but it can also be seen in the setting of normal x-rays secondary to weakness in the large muscle groups of the leg. “It’s as if the joint is like a seesaw that has too many children on one side.

That extra stress on that side of the seesaw is similar to what one area of the knee is subject to every time you bend and straighten the joint.” Because patellofemoral pain inhibits the quadriceps muscle (the major muscle in front of the thigh) from doing its “job” of unloading stress on the kneecap, once pain occurs, it often progresses.
