Patellofemoral Arthritis

Introduction

Patellofemoral arthritis affects the knee at the point where the end of the femur meets the patella (the kneecap). Those who suffer from this condition often experience pain when using stairs and shifting from a sitting to standing position, or feel instability in the knee. This condition is most often degenerative, meaning the cartilage wears away over time. It can also be caused by a fracture of the kneecap which, over time, can lead to arthritis or from uneven cartilage behind the knee cap. Occasionally, maltracking of the kneecap can lead to increased stress on the cartilage, eventually wearing it down. 

Symptoms of this condition include pain in the front of the knee which may be present both at rest or during activity. Pain may also be experienced when the patient is kneeling, squatting, using stairs or standing. Some patients experience a cracking or popping sensation in their knee, while those with an advanced condition may experience their knee catching or becoming stuck when attempting to straighten their knee.
