Sports Medicine: Patellofemoral Disorders
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.
