Kidney Int. Arthrofibrosis of the knee. Childhood adversity such as neglect or abuse is associated with disease and disability later in life,85 causing higher Th17 cell numbers, a higher IL-6 response to stress, and autoimmune and inflammatory diseases.86 Depression and associated poor rehabilitation compliance are sometimes cited as causative factors for arthrofibrosis,7 however, it is interesting to note that depression is strongly associated with inflammation, and inflammation can cause depression.87,88 Therefore, it seems likely that the inflammatory processes associated with active arthrofibrosis cause depression. In vitro and animal studies show that metformin reduces collagen deposition and proliferation of fibroblasts after initiation of fibrosis compared to non-treated controls,159,264,270 with some of these studies also showing reduced levels of -SMA expression. This suggests that this virus is a significant risk factor for arthrofibrosis, with the risk potentially higher for post-operative patients and those with residual fibrosis. . 2015, 114 (2015). Thanks also to patients on the website KNEEguru who contributed their experiences of arthrofibrosis. 595, 6377 (2017). . Reassessing the role of the NLRP3 inflammasome during pathogenic influenza A virus infection via temporal inhibition. For a review of potential pharmacological therapies to treat fibrosis see Nanthakumar et al.17, Mesenchymal stem cells (MSCs) are able to home in on injured tissue and differentiate into different tissue types.290 They modulate the immune system by altering the activation and proliferation of immune cells, and are being tested in clinical trials for the treatment of lung fibrosis.174,291,292, Some studies have reported positive results using MSCs to treat fibrosis of organs in mice, however, MSC treatment remains controversial. However, the potential benefits of surgery must be weighed against the risks, which include increased dysregulation of fibrogenesis in response to the surgical injury. Tech. Arthrofibrosis is the pathologic stiffening of a joint due to an exaggerated inflammatory fibrotic response leading to the development of non-compliant scar tissue 1. Many of the inflammatory cytokines that are produced in response to influenza, particularly IL-1, IL-6 and TNF-330,331 are known to cause the differentiation of fibroblasts into myofibroblasts103 and are important cytokines in arthrofibrosis (see above). These problems . heat - either locally or generally over the entire knee. CPM may be useful for minimising joint contractions, however, research into the use of CPM to treat arthrofibrosis is lacking. & Li, M. O. Liver Physiol. 98, 95102 (2016). Sports Med. & Gallucci, R.

The infrapatellar fat pad of patients with osteoarthritis has an inflammatory phenotype. The number of myofibroblasts in tissue from arthrofibrotic knees can be ten times higher than in healthy subjects.233 Ruppert et al.234 observed co-localisation of -catenin and the tight junction protein ZO-1 in myofibroblasts which may cause increased adhesions and mechanical loading of cells. However, it is well established that the genders differ in their immunological responses, with 80% of autoimmune disease occurring in women.66 Being female is also a risk factor for OA,38,67 with more women undergoing TKR than men, despite women having a greater unmet need for this surgery.68 Recent research shows that OA is initiated and progressed by inflammation (see below in Risk factors), and that patients with OA have high levels of inflammatory cytokines in the knee.58. 20, 133138 (2005). Cell. Glaser, S. et al. Res. The most common method is to use a surgical laser. The reasons for these significantly different outcomes are not clear, but may include the level of inflammation, the time between surgeries, surgical technique, rehabilitation protocols and individual predisposition through genetic or other factors. Adv. Good results can be obtained using . Zheng, W. et al. Histochemical and immunohistochemical studies have significantly advanced the understanding of the pathogenesis of arthrofibrosis, and fibrosis in general, demonstrating alterations in tissue composition and structure and cell activity. Endoglin differentially regulates TGF-B-induced Smad2/3 and Smad1/5 signalling and its expression correlates with extracellular matrix production and cellular differentiation state in human chondrocytes. Gut bacteria produce short-chain fatty acids from non-digestible dietary fibre, which counter inflammation and suppress the cleavage of protease caspase-1 and secretion of IL-18.302, In addition, consumption of soy products may help reduce the levels of inflammatory cytokines.

Unfortunately, as with research publications, these forums are largely silent on the long-term outcomes for patients with permanent active arthrofibrosis. 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.

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.

Quality research into the efficacy of CPM for patients with arthrofibrosis, rather than the general orthopaedic patient community, is urgently needed. Molecules 20, 573594 (2015). Arthrofibrosis is defined as a complication of injury or trauma where an excessive scar tissue response leads to painful restriction of joint motion, with scar tissue forming within the joint and surrounding soft tissue spaces and persisting despite rehabilitation exercises and stretches. 6, e1001136 (2010).

The proinflammatory peptide substance P promotes bloodbrain barrier breaching by breast cancer cells through changes in microvascular endothelial cell tight junctions. Manferdini, C. et al. It is difficult to determine how successful surgery is for treating arthrofibrosis.6 Patients differ widely in the severity of symptoms, degree of inflammation and extent of fibrosis within and around the joint, and surgical treatments also vary greatly in extent. 39, 4658 (2017). Cardiol. 160, 35133521 (1998). As a common complication following total knee arthroplasty, arthrofibrosis is a significant cause of pain and disability for patients, with up to 25% of patients requiring . Nonetheless, the few studies of MSCs in humans to date have not demonstrated worsening fibrosis.296,297, It is known that MSCs can contribute to the growth of tumours,290 but a recent small phase I clinical trial of MSCs in the treatment of pulmonary fibrosis reported no adverse safety outcomes.292 Different preparations of MSCs differ in their efficacy, perhaps because of variation in their expression of anti-inflammatory genes.298 The age and origin of MSCs may affect the outcome of fibrosis therapy, as MSCs from different lineages express different proteins that affect their therapeutic potential.299 MSCs from the IFP of patients with OA appear to inhibit the production of inflammatory cytokines in vitro.300. Gut 57, 223231 (2008). J. 2021;42(5):398-415. doi:10.1016/j.tips.2021.02.007. Sports Med. . 20, 25152532 (2014). Sci. Cell Biol. J. Mol. Some patients may have a genetic predisposition for developing fibrosis,91 with a twin study finding there was a genetic component to shoulder arthrofibrosis.92 Because multiple biological pathways impact on the pathology of arthrofibrosis, it is likely that there are many types of mutations that can affect the risk of developing it, including mutations in the immune system, TGF- signalling and genes involved in the synthesis or degradation of collagen. 119, 32133225 (2009). Altintas, N. et al. Proc. This study showed that rates of arthrofibrosis requiring surgical treatment were significantly higher for ACL reconstruction compared to meniscectomy and microfracture.5 However, even exploratory arthroscopies are capable of causing arthrofibrosis.12.

Once established these factors and others, including extensive collagen cross-linking, create a complex web of positive feedback processes that establish a new pathological homoeostasis that maintains excessive ECM accumulation and low-grade inflammation. Kidney Int. Favejee, M. M., Huisstede, B. M. A. Although the term ECM includes a wide variety of biological components we use this established terminology when discussing fibrotic scar tissue. Elwenspoek, M. M. C. et al. CAS Am. Immunity 40, 4050 (2014). A Surgical lysis and removal of ECM, and MUA, remain the primary treatments for arthrofibrosis. Post-operative use of continuous passive motion (CPM) is sometimes prescribed to increase ROM,52,235 but remains controversial, most likely due to the associated expense and inconvenience.236,237 This results in many patients not having access to regular CPM.235. Rates of arthrofibrosis requiring a manipulation under anaesthesia (MUA) or arthroscopy within 6 months of the initial surgery were up to 8%. Often times both the arms and legs are affected. The IFP may become fibrotic and impinge in the joint when the knee is flexed, creating further inflammation and fibrosis, loss of flexion and pain.24 The IFP is a store of immune cells that secrete inflammatory cytokines under stressful conditions25 (see Risk assessment), and can fill with ECM when adipose cells transform into fibrous tissue.26, a Sagittal fast spin echo intermediate-weighted image of a 33-year-old woman with clinical stiffness following anterior cruciate ligament (ACL) reconstruction, showing scarring of the synovium around the ACL reconstruction (long arrow) as well as the central portion of the deep infrapatellar fat pad (short arrow) and the lining of the suprapatellar recess (oval). patellar (kneecap) immobility.

It is perhaps best defined as a condition of restricted knee motion characterized by dense proliferative scar formation, in which intra-articular and extra-articular adhesions can progressively . Many cytokines have been associated with fibrosis, the most important being TGF-. If they don't help, surgery may be needed to remove the excess scar tissue. Itoi, E. et al. In other surgery, such as TKR and reconstructive surgery using artificial ligaments, the implantation of a prosthesis triggers the formation of fibrotic tissue as the body attempts to encapsulate the foreign material.83 Implants such as screws that impinge on tissues also cause an inflammatory reaction,84 and may promote arthrofibrosis of TKRs that are not well fitted. 64, 615626 (2015). which can restrict joint movement and cause significant pain and disability. 1, 4752 (2011). PubMed Central Treatment of lung fibrosis has improved recently with the introduction of pirfenidone and nintedanib.251 Pirfenidone downregulates inflammatory cytokines including TNF-, IL-1 and IL-6 in addition to its anti-fibrotic effects of blocking TGF- stimulated collagen production, production of PDGF, -SMA and fibroblast proliferation.251 These treatments may be beneficial for treating arthrofibrosis either on their own, or in combination with other therapies,since therapies for treating organ fibrosis are likely to be effective for the treatment and prevention of arthrofibrosis.

NF-B regulates genes and cells involved in inflammatory responses,179 including the activation, differentiation and function of inflammatory T cells and inflammasomes.120,134 It directly and indirectly promotes Th17 differentiation, and dysregulated production of NF-B is associated with a range of autoimmune and inflammatory diseases.120, NF-B upregulates the transcription of chemokines and inflammatory cytokines including TNF-, IL-1 and IL-6 in a range of innate immune cells, inducing inflammation.120,157 NF-B in macrophages and fibroblasts is activated by TGF--activated kinase 1, as well as many of the inflammatory cytokines induced by it,120 leading to another feedback loop of inflammation and fibrosis. J. Med. Scar tissue is dense and fibrous. The most common reason for total knee replacement surgery is arthritis of the knee joint. Intermittent fasting attenuates inflammasome activity in ischemic stroke. 119, 13261336 (2018). This, together with the ability to diagnose arthrofibrosis very early in the process of ECM formation suggests that arthrofibrosis research would be a useful testing ground for fibrosis treatments in general. He served as assistant team physician to Chivas USA (Major League Soccer) and the United States men's and women's national soccer teams. In this case the patients flexion only dropped below 100 for a 1-week period after the third operation, and her extension was never worse than 0. This is probably due to tearing of tissues during the process and bleeding. A diet rich in omega 3 fatty acids is recommended for inflammatory conditions (see above in Resolvins). J. Verjee et al.287 demonstrated that TNF- antibodies inhibited the contractions of myofibroblasts taken from patients with Dupuytrens disease, which involves progressive fibrosis of the palm.

This approach could be used to prevent the return of arthrofibrosis at the time of surgery to lyse adhesions and remove ECM. Arthrofibrosis (from Greek: arthro- joint, fibr- fibrous and -osis abnormality) is an inflammatory condition that leads to the production of excessive scar tissue in or around major joints. Badalamente, M. A. Invest. 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. Metformin inhibits aldosterone-induced cardiac fibroblast activation, migration and proliferation in vitro, and reverses aldosterone+salt-induced cardiac fibrosis in vivo. Despite the increasing use of preventative measures after surgery, it appears that arthrofibrosis rates have remained relatively constant.29 A lack of an understanding of the role that inflammation plays in arthrofibrosis can lead to overly aggressive physical therapy programmes, with papers frequently recommending aggressive physical therapy as soon as possible after surgery.7,42,47,48 However, aggressive exercise can initiate or worsen arthrofibrosis32,48 because exercise triggers an inflammatory response49 including an increase in inflammatory cytokines, collagen production and TGF-,50,51 factors that are dysregulated in fibrosis (see below). , Johnson, C. & McConnell, J.
