The pathophysiology of patellofemoral pain: a tissue homeostasis perspective.

چکیده

UNLABELLED Fundamental to rational, safe, and effective treatment for any orthopaedic condition is an accurate understanding of the etiology of the symptoms. The decades-old paradigm of a pure structural and biomechanical explanation for the genesis of patellofemoral pain is giving way to one in which biologic factors are being given more consideration. It is increasingly evident that a variable mosaic of possible pathophysiologic processes, often caused by simple overload, best accounts for the etiology of patellofemoral pain in most patients. Inflamed synovial lining and fat pad tissues, retinacular neuromas, increased intraosseous pressure, and increased osseous metabolic activity of the patella all have been documented as contributing to the perception of anterior knee pain. Considered together, these processes can be characterized as loss of tissue homeostasis and can be seen as providing a new and alternative explanation for the conundrum of anterior knee pain. Certain high loading conditions of the patellofemoral joint can be of sufficient magnitude to induce the symptomatic loss of tissue homeostasis so that, once initiated, they may persist indefinitely. From this new biologic perspective, it clinically matters little what structural factors may be present in a given joint (such as chondromalacia, patellar tilt or a Q angle above a certain value) if the pain free condition of tissue homeostasis is safely achieved and maintained. LEVEL OF EVIDENCE Level V (expert opinion). See the Guidelines for Authors for a complete description of levels of evidence.

Patellofemoral Pain Current Concepts: An Overview

The conceptualization of factors responsible for the etiology of patellofemoral pain are changing. In the recent past, chondromalacia and malalignment were believed to be most important factors relative to the genesis of anterior knee pain symptoms. However, new evidence from Europe and North America indicates other factors may be more important, such as overuse of anatomically normal patellofe...

Patellofemoral Pain: An Enigma Explained by Homeostasis and Common Sense.

We present a rational, scientific, low-risk approach to patellofemoral pain (anterior knee pain) based on an understanding of tissue homeostasis. Loss of tissue homeostasis from overload and/or injury produces pain. Bone overload and synovial inflammation are common sources of such pain. Chondromalacia and malalignment are findings that almost always do not need to be "corrected" to relieve pai...
