Sci. Arthrofibrosis, a buildup of scar tissue after surgery that causes stiffness and pain, can lead to severe disability, making it nearly impossible to bend the joint. Many patients believe that overly aggressive exercise rehabilitation soon after surgery was detrimental to their recovery, and strongly advocate that arthrofibrosis sufferers listen to their knee, and do not push too hard to fit in with exercise regimes and expected recovery timetables. 2019;7:9. doi:10.1038/s41413-019-0047-x, Frye BM, Floyd MW, Pham DC, Feldman JJ, Hamlin BR. J. Arthroplast. NLRP3 inflammasome activation is required for fibrosis development in NAFLD. These treatments include surgical interventions, such as arthroscopic lysis and debridement of ECM, open surgery to remove ECM and release of tendons and ligaments, and MUA.35 Other treatments include bracing, corticosteroids and physical therapy3,33 (Table2). However, by understanding the pathology of the condition, it may be possible to prevent or successfully treat arthrofibrosis,13,42 and a number of factors are known to be involved (Table1). Pines, M. & Spector, I. Halofuginonethe multifaceted molecule. Felisbino, M. B. Koca, S. S. et al. On a cellular level arthrofibrosis is characterised by upregulated myofibroblast proliferation with reduced apoptosis, adhesions, aggressive synthesis of ECM that can fill and contract joint pouches and tissues and often also heterotrophic ossification.1,13,14 Although ECM is necessary for healing and wound repair, dysregulation of production and degradation leads to pathologic fibrosis.1,15 While there are relatively few studies into the pathogenesis and molecular biology of arthrofibrosis compared to other fibrotic diseases,1 there are common pathogenic pathways.16,17,18.

A team led by Kayley Usher and Jiake Xu from the University of Western Australia in Crawley review the immune cells, signalling molecules and risk factors underpinning arthrofibrosis, a complication of surgery or trauma, in which scar tissue accumulates leading to painful restriction of motion in the shoulders, knees or other joints. 130, 575586 (2016). Autoimmun. Pract. In support of this, Panni et al.7 report that painful stiff knees do not respond well to arthroscopic surgery to lyse adhesions, and Babis et al.27 report that surgery to treat arthrofibrosis in TKR patients resulted in worse outcomes for pain in all patients, with some also losing flexion. However, arthrofibrosis has been reported to be one of the most frequent complications in TKA, which lead to the limited range of motion (ROM) in knee joint flexion and extension. Risk factors for total knee arthroplasty aseptic revision. The NLRP3 inflammasome is a key player in sterile inflammation, and is associated with a range of auto-inflammatory and autoimmune diseases.2 Tissue damage and the accumulation of damaged mitochondria increases mitochondrial ROS production, which, along with other signals activates NLRP3 and stimulates processing of IL-1 pre-cursers into the biologically active form.2,136,137 NLRP3 also regulates ROS production by mitochondria.138 The activation of capase-1 by NLRP3 activates IL-1 and IL-18 precursors,2,137 and also causes the secretion of IL-1 and fibroblast growth factor 22. 1.

The scar tissue inside the joint adheres to surrounding tissues and contracts, and this frequently reduces the range of motion (ROM) of the joint. Myofibroblast differentiation is a particularly attractive target,46 and epigenetic reprogramming and de-activation of myofibroblasts could control dysregulated TGF- signalling, inflammatory cytokine production and ECM synthesis and cross-linking.219 However, further research is needed to clarify the functions of specific inhibitors and promoters, as they can affect many cell types and can have off-target effects including the deacetylation of proteins.220,279 Zeybel et al.278 demonstrated that myofibroblasts in liver fibrosis could be targeted using liposomes coated with myofibroblast-specific antibodies to deliver epigenetic drugs, potentially side-stepping potential issues with off-target effects.

Patients frequently suffer constant pain, severe limitations on physical activity and difficulty sleeping, sitting and weight bearing.12 These symptoms may lead to the loss of job/career and difficulty socialising and performing daily living tasks, negatively impacting physical and emotional well-being. Int. This could potentially stop the pathological cascade of dysregulation and positive feedback that results in permanent active fibrosis,214 while also preventing damage to joint structures such as cartilage and ligaments that occurs with tissue contraction and altered biomechanics.

Arthrofibrosis is a complication of injury or trauma to a joint. J. Allogeneic human mesenchymal stem cells in patients with idiopathic pulmonary fibrosis via intravenous delivery (AETHER): a phase I safety clinical trial. Both treatments damage tissues, and tissue injury stimulates an inflammatory response239 that may cause further fibrogenesis. During normal wound healing and resolution of inflammation some myofibroblasts become apoptotic, while others revert to the original cell type, however, the processes by which this occurs are not yet understood.90 In fibrosis epigenetic alterations in myofibroblasts increase the activity of inflammatory and pro-fibrotic genes118 (see below in Epigenetic alterations), and appear to serve as a type of memory of the insult.108 Myofibroblasts that have reverted back to fibroblasts are more likely to become re-activated when exposed to further insult.60,90 This has implications for repeated joint surgeries as fibrosis may resolve naturally and unnoticed, but the presence of reverted fibroblasts that serve as a store of pre-fibrotic cells may leave the patient susceptible to arthrofibrosis after subsequent surgeries, as discussed earlier.

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. It has been most extensively studied in the knee . Histone deacetylase inhibitors have been effective in treating liver and kidney fibrosis in rodents,218 and Schuetze et al.279 demonstrated that diverse histone deacetylase inhibitors were able to suppress proliferation of cardiac fibroblasts in vitro.

Cochrane Database Syst. The type of T cell response to inflammation controls the magnitude of fibrosis, with Th2 cells promoting the production of ECM and fibrosis, while Th1 cells are typically suppressive.62,116 Th17 cells are a subset of T reg cells that differentiate in the periphery in the presence of IL-1, IL-6 and TGF-.129 They secrete IL-17, a cytokine that is important for the activation and migration of immune cells, inducing them to secrete inflammatory cytokines and chemokines.129 Th17 cells are suppressed by the amino acid limitation response, which also enhances autophagy.102, Inflammasomes are intracellular protein complexes that activate an inflammatory cascade by upregulating the production and maturation of inflammatory cytokines IL-1 and IL-18.2,120,130 Activated inflammasomes play a central role in fibrosis of organs including the liver,131,132 lungs133 and kidneys,130 upregulating -SMA, connective tissue growth factor and collagen type I131.

In addition, studies of surgical procedures to treat arthrofibrosis are often poor quality.36 They frequently have small sample sizes, sampling bias and reporting bias,5 and are typically not comparative33 or controlled, complicating the interpretation of these procedures.36 The reported high rates of success of surgeries to treat arthrofibrosis and lack of adverse outcomes do not correlate well with outcomes reported by patients on patient websites such as KNEEguru241 and indeed it is understood that published results of knee surgery including TKRs by specialised surgical centres may be misleading and overly optimistic.68,242.

Liver fibrosis is another possible parallel, as it can sometimes be stopped and even reversed60 using anti-inflammatory or anti-viral medications, but can turn into active, progressive fibrosis.61 Active fibrosis results from a switch from an initial Th1 inflammatory cell response to a Th2 cell response with prolonged exposure to an inflammatory stimulus. Increased formation of pyridinoline cross-links due to higher telopeptide lysyl hydroxylase levels is a general fibrotic phenomenon. .

Surgical lysis and removal of ECM, and MUA, remain the primary treatments for arthrofibrosis. 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. The first group of patients is described as having complex regional pain syndrome (CRPS), a type of neuropathic pain caused by nerve damage, and the authors recognise that this group of patients should not be operated on.

Arthrofibrosis treatment is extremely important and must be performed by a specialized surgeon trained in diagnosing and treating the exact cause of knee arthrofibrosis. Thus myofibroblasts resist apoptosis and are able to maintain themselves by secreting TGF-15 and inflammatory cytokines, activating immune cells and further fibrosis. The listing for a particular impairment describes a degree of severity that Social Security Administration presumes would prevent a person from performing substantial work. Exp. Discov. Rheumatology 42, 739742 (2003). Histone modifications include both acetylation and methylation of nuclear histones that package DNA, with the former promoting gene transcription218 and the latter typically suppressing it.147,220 TGF- is known to alter histone modifications, and acetylation of histones is associated with myofibroblast activation, increased production of inflammatory cytokines220 and increased SMAD3 transcription.225 Non-histone protein methylation can also alter the activity of transcription factors and promote TGF- signalling by decreasing Smad7 protein stability.226 Smad7 is an inhibitor of TGF- expression.

There are several fibrotic diseases of the lungs, including simple pneumoconiosis, in which fibrosis begins and stops, and progressive massive fibrosis, in which extensive fibrosis progresses until fatal.59 Simple pneumoconiosis can turn into progressive massive fibrosis if exposure to dust and inflammation continues. In addition, a conservative approach to rehabilitation exercises is recommended with adjustments made according to how the joint responds. The first treatment for arthrofibrosis is rest, ice, and anti-inflammatory medications to reduce the pain and swelling. Hemsley, K.
