ReviewPlantar fasciopathy: Revisiting the risk factors
Introduction
Similar to other conditions where pathological origin is unclear, chronic plantar heel pain has become a generalized term that includes several pathological conditions that affect the heel [1]. Heel pain may be the result of arthritic, neurological, traumatic, or other systemic conditions, although the overwhelming cause is mechanical in origin [2], [3].
Plantar fasciitis is a commonly reported cause of plantar heel pain [4], [5], [6], [7]. Terminology for this condition is confusing, as a degenerative process of micro tears (fasciosis) similar to tendinosis, a degeneration of collagen in tendons [8], and fascial thickening predominates over inflammatory changes. Similar histopathological changes have been reported in tendon and ligament disorders elsewhere [8] hence redefinition of the condition from plantar fasciitis to plantar fasciopathy (PF) may better reflect the underlying pathology within the fascia, which rarely includes inflammatory cells.
The purpose of this paper is to critically reevaluate risk factors for PF.

Discussion
Although PF is the most common soft-tissue cause of heel pain [5], [19] its aetiology is not fully understood [22], [38], [39], [40], [41]. The condition is considered to be multifactorial [6], [17], [20] and numerous risk factors are implicated in its development (Table 1). The evidence supporting these factors is limited and their relative importance is unclear. Several causes have been hypothesized, with the most common being overuse due to prolonged weight-bearing, obesity, unaccustomed
Conclusion
Plantar fasciopathy is a common cause of sub calcaneal heel pain. The condition represents an important economic burden to health services due its potential to become chronic in nature. Studies supporting both intrinsic and extrinsic risk factors suggest complex multifactorial soft tissue pathology. Research to examine a possible genetic basis for developing this condition may advance our knowledge of the intrinsic risk profile, provide a novel and alternative approach to understanding this
