Hello my name is Tom Smallman, and I am an ex-military orthopaedic surgeon practicing at the Auburn Community Hospital in Upstate New York.
What is 'Anterior Knee Pain'?
Anterior knee pain is a symptom complex, dominated by 'pain in the front of the knee'.
This characteristic pain tends to be associated with:
- forced activities -- squatting, weight bearing activities, running.
- prolonged sitting – producing stiffness, pain, or both, relieved by straightening (extending) the knee.
- on getting up from sitting, the pain may be severe, then diminishes and even disappears as the individual keeps walking.
- the “theatre sign” in some - where the individual seeks to sit at the end of any row of chairs, to allow the relief afforded by knee extension and even standing up.
- problems with walking - where the person may exhibit weakness, giving way of the knee, and 'catching'.
- stair climbing producing pain when weight is applied on the leg, when going up or down stairs.
- snapping, popping, or crunching in the knee occurring with activity as simple as walking, that may be accompanied by pain, which may be so severe that the individual feels that the knee locks.
