The pathogenesis depends on the mechanism and severity of the precipitating neuromuscular disorder. The breakdown products of soy isoflavones, daidzein and genistein, are known to be antioxidant and anti-inflammatory compounds, but their usefulness in treating arthrofibrosis has had only limited testing in non-human animals.

Irradiation in the treatment of arthrofibrosis after total knee arthroplasty: a preliminary trial. Importantly, SPMs were shown to be anti-fibrotic in organs including the kidney190 and liver.191 PDGF-induced myofibroblast proliferation is inhibited,190 along with the production of inflammatory cytokines, and SPMs may represent an important new treatment for fibrosis.190 Although SPMs have a short half-life in vivo, more stable synthetic analogues have been developed,192 and may become a useful therapy for a range of inflammatory diseases and fibrosis. Understanding arthrofibrosis, its causes, rates of occurrence and the success or failure of treatments has been complicated because the condition was poorly defined.32 Definitions have varied widely and are sometimes subjective, as are measures of treatment outcomes.33 Recently, an international panel of experts from multiple medical disciplines developed a consensus definition and classification of knee arthrofibrosis, which stated post-operative fibrosis of the knee was defined as a limited ROM in extension and/or flexion, measured by active flexion and extension, which was not caused by infection of other specific causes.32 Mild, moderate and severe arthrofibrosis was classified as flexion range of 90100, 7089, and less than 70, respectively, and/or a loss of extension of 510, 1120 and more than 20o, respectively.32 The presence of pain was acknowledged as being an important aspect of the condition. Blockade of KCa3.1 ameliorates renal fibrosis through the TGF-beta1/Smad pathway in diabetic mice. Biomarkers to assess the risk of developing post-surgical arthrofibrosis are urgently needed. N. Engl. Intermittent fasting has profound positive effects on many health measures and can improve functional outcomes for many diseases.313 Animal research shows that intermittent fasting is protective against fibrosis of organs,314 and it is also known suppress inflammation313,315 and downregulate the inflammatory cytokines IL-1, IL-6 and TNF- in humans.316 Intermittent fasting suppresses the activity of NLRP3 inflammasomes,313 providing what appears to be a cumulative anti-fibrotic effect. TGF- also upregulates a wide range of pro-fibrotic micro-RNAs and long noncoding RNAs, and downregulates anti-fibrotic micro-RNAs.147 In liver disease long noncoding RNAs and other noncoding RNAs can promote or reverse fibrosis via a variety of mechanisms, including upregulation of CTGF227 and TGF- signalling.228, Epigenetic alterations are likely to be significant factors in persistent active arthrofibrosis, as has recently been shown for lung fibrosis,195 other fibrotic diseases108,147 and cardiorespiratory abnormalities from hypoxia-induced DNA methylation and persistent increases in ROS.229. Curr. Nonsteroidal anti-inflammatory drugs (NSAIDS) may prolong chronic inflammation if used for more than 48h because the resulting inhibition of COX-2193 causes inhibition of resolvin production and other SPMs.56,194 COX-2 is an important anti-fibrotic enzyme.195 The chronic inflammation induced by long-term NSAIDS use is known to activate fibrosis of the kidneys16,196 and lung.195 However, it is not known how NSAIDS use affects arthrofibrosis, despite it being a commonly prescribed treatment.197 Importantly, aspirin is an exception as it acetylates COX-2, favouring the production of lipid mediator precursors over pro-inflammatory prostanoids.192, Hypoxia is the lack of sufficient oxygen to carry out normal cellular processes, and occurs in tissue surrounding wounds.198 Hypoxia is believed to be important in the development of fibrosis,198,199 via wide-ranging effects.

Neutralising antibodies to IL-11 and the deletion of IL-11 receptors inhibited the effects of TGF-, suggesting new therapeutic targets for fibrosis.143 IL-11 is expressed by fibroblasts and other cells.164 It is a member of the IL-6 family of cytokines, and is also implicated in tumour progression.165, TNF- is thought to be important in the pathogenesis of fibrosis.46,116,166,167,168 It is a pleiotropic inflammatory cytokine169 that causes significant upregulation of TGF- production168,170 and receptor expression140 and may stimulate fibroblast growth and collagen type I expression.171 TNF- also causes fibroblast-like differentiation and inflammation,138 and PGE2 expression.172 TNF- and IL-1 upregulate cyclooxygenase 2 (COX-2) synthesis in response to an insult.158 These cytokines also induce the expression of intracellular adhesion molecule-1 (ICAM-1),158 expressed in vascular endothelium, macrophages and lymphocytes, and associated with the development of fibrosis.59 Roberts et al.152 reported that TNF- and IL-1 upregulated MMPs in vitro, potentially providing some anti-fibrotic effects, however, these cytokines also have pro-fibrotic effects. These diverse stimuli include ROS, adenosine triphosphate (ATP), mitochondrial DNA and proteins released from damaged ECM, such as hyaluronan, heparin sulphate and biglycan.2,120.

The release of stress created by the lysis of ECM can potentially interrupt the feedback loop between myofibroblast activation due to mechanical loading and resulting contraction, in the process encouraging apoptosis of myofibroblasts.113 In addition, the removal of ECM during surgery removes bound pro-fibrotic mediators, including TGF-.108, Nonetheless, the benefits of surgical lysis and MUA should be tempered by an understanding of the problems associated with these procedures. Bonniaud, P. et al. Substance P selectively activates TNF-alpha gene expression in murine mast cells. TNF- has pleiotropic effects, and its role in organ fibrosis remains controversial.285,286 In addition, it may have different effects in different organs.285 The importance of TNF- in established fibrosis remains to be clarified, and further research is required to understand the effectiveness of TNF- antibodies as a therapeutic agent for treating fibrosis.

It has high-tensile strength that prevents normal stretching, and in fibrosis there is a higher ratio of collagen type I to stretchy elastin, compared to healthy tissues.103 In addition to altered composition, fibrotic ECM has extensive cross-linking that makes it very difficult to degrade.89,104 In particular, levels of hydroxyallysine cross-linking is increased, and appears to lead to irreversible collagen accumulation105 together with other effects on cell signalling and ECM synthesis.89.
