Establishing minimum clinically important difference values for the Patient-Reported Outcomes Measurement Information System Physical Function, hip disability and osteoarthritis outcome score for joint reconstruction, and knee injury and osteoarthritis out

AIM To establish minimum clinically important difference(MCID) for measurements in an orthopaedic patient population with joint disorders.METHODS Adult patients aged 18 years and older seeking care for joint conditions at an orthopaedic clinic took the Patient-Reported Outcomes Measurement Information System Physical Function(PROMIS~? PF) computerized adaptive test(CAT), hip disability and osteoarthritis outcome score for joint reconstruction(HOOS JR), and the knee injury and osteoarthritis outcome score for joint reconstruction(KOOS JR) from February 2014 to April 2017. MCIDs were calculated using anchorbased and distribution-based methods. Patient reports of meaningful change in function since their first clinic encounter were used as an anchor.RESULTS There were 2226 patients who participated with a mean age of 61.16(SD = 12.84) years, 41.6% male, and 89.7% Caucasian. Mean change ranged from 7.29 to 8.41 for the PROMIS~? PF CAT, from 14.81 to 19.68 for the HOOS JR, and from 14.51 to 18.85 for the KOOS JR. ROC cut-offs ranged from 1.97-8.18 for the PF CAT, 6.33-43.36 for the HOOS JR, and 2.21-8.16 for the KOOS JR. Distribution-based methods estimated MCID values ranging from 2.45 to 21.55 for the PROMIS~? PF CAT; from 3.90 to 43.61 for the HOOS JR, and from 3.98 to 40.67 for the KOOS JR. The median MCID value in the range was similar to the mean change score for each measure and was 7.9 for the PF CAT, 18.0 for the HOOS JR, and 15.1 for the KOOS JR.CONCLUSION This is the first comprehensive study providing a wide range of MCIDs for the PROMIS? PF, HOOS JR, and KOOS JR in orthopaedic patients with joint ailments.

Aberrant activation of latent transforming growth factor-β initiates the onset of temporomandibular joint osteoarthritis

There is currently no effective medical treatment for temporomandibular joint osteoarthritis(TMJ-OA) due to a limited understanding of its pathogenesis. This study was undertaken to investigate the key role of transforming growth factor-β(TGF-β)signalling in the cartilage and subchondral bone of the TMJ using a temporomandibular joint disorder(TMD) rat model, an ageing mouse model and a Camurati–Engelmann disease(CED) mouse model. In the three animal models, the subchondral bone phenotypes in the mandibular condyles were evaluated by μCT, and changes in TMJ condyles were examined by TRAP staining and immunohistochemical analysis of Osterix and p-Smad2/3. Condyle degradation was confirmed by Safranin O staining, the Mankin and OARSI scoring systems and type X collagen(Col X), p-Smad2/3 a and Osterix immunohistochemical analyses. We found apparent histological phenotypes of TMJ-OA in the TMD, ageing and CED animal models, with abnormal activation of TGF-βsignalling in the condylar cartilage and subchondral bone. Moreover, inhibition of TGF-β receptor I attenuated TMJ-OA progression in the TMD models. Therefore, aberrant activation of TGF-β signalling could be a key player in TMJ-OA development.

Stem cell application for osteoarthritis in the knee joint: A minireview

Knee osteoarthritis is a chronic, indolent disease that will affect an ever increasing number of patients, especially the elderly and the obese. It is characterized by degeneration of the cartilage substance inside the knee which leads to pain, stiffness and tenderness. By some estimations in 2030, only in the United States, this medical condition will burden 67 million people. While conventional treatments like physiotherapy or drugs offer temporary relief of clinical symptoms, restoration of normal cartilage function has been difficult to achieve. Moreover, in severe cases of knee osteoarthritis total knee replacement may be required. Total knee replacements come together with high effort and costs and are not always successful. The aim of this review is to outline the latest advances in stem cell therapy for knee osteoarthritis as well as highlight some of the advantages of stem cell therapy over traditional approaches aimed at restoration of cartilage function in the knee. In addition to the latest advances in the field, challenges associated with stem cell therapy regarding knee cartilage regeneration and chondrogenesis in vitro and in vivo are also outlined and analyzed. Furthermore, based on their critical assessment of the present academic literature the authors of this review share their vision about the future of stem cell applications in the treatment of knee osteoarthritis.

Association between facet joint osteoarthritis and the Oswestry Disability Index

AIM:To investigate the correlation of facet joint osteoarthritis(FJOA) at lumbar levels L4/L5 and L5/S1 and the Oswestry Disability Index(ODI).METHODS:The study involved lumbar MRIs of 591 patients with a mean age of 47.3 years.The MRIs of the lumbar spine were performed on a 1.5 Tesla scanner(Magnetom Avanto,Siemens AG,Erlangen,Germany) using a dedicated receive only spine coil.After initial blinding,each dataset was evaluated by 2 board certified radiologist with more than 5 years experience in musculoskeletal imaging.In total 2364 facet joints were graded.Degenerative changes of the facet joints were evaluated according to the 4-point scale as proposed by Weishaupt et al Functional status was assessed using the ODI.The index is scored from 0 to 100 and interpreted as follows:0%-20%,minimaldisability; 20%-40%,moderate disability; 40%-60%,severe disability; 60%-80%,crippled; 80%-100%,patients are bedbound.Spearman’s coefficient of rank correlation was used for statistical analysis,with significance set at P 【 0.05.RESULTS:In total 2364 facet joints at lumbar levels L4/5 and L5/S1 were analysed in 591 individuals.FJOA was present in 97%(L4/L5) and 98%(L5/S1).At level L4/5(left/right) 17/15(2.9%/2.5%) were described as grade 0,146/147(24.7%/24.9%) as grade 1,290/302(49.1%/51.1%) as grade 2 and 138/127(23.4%/21.5%) as grade 3.At level L5/S1(left/right) 10/11(1.7%/1.9%) were described as grade 0,136/136(23.0%/23.0%) as grade 1,318/325(53.8%/55.0%) as grade 2 and 127/119(21.5%/20.1%) as grade 3.Regarding the ODI scores,patients’ disability had a minimum of 0% and a maximum of 91.11% with an arithmetic mean of 32.77% ± 17.02%.The majority of patients(48.39%) had moderate functional disability(21%-40%).There was no significant correlation between FJOA and ODI on both sides of lumbar level L4/5 and on the left side of lumbar level L5/S1.A weak positive correlation was evaluated between ODI and FJOA on the right side of lumbar level L5/S1.CONCLUSION:The missing correlation of FJOA and ODI confirms our clinical experience that imaging alone is an insufficient approach explaining low back pain.Clinical correlation is imperative for an adequate diagnostic advance in patients with low back pain.

Synovial Neuronal Changes in Knee Joint Osteoarthritis

Purpose: The purpose is to study whether pain and inflammation in knee joint osteoarthritis (OA) are associated with local synovial neuronal changes. Methods: Synovial biopsies were harvested from the medial and lateral knee compartments from OA patients undergoing total joint replacement surgery. All patients had predominant pain at the medial joint compartment. Pain and knee joint function were evaluated by knee society score (KSS). Synovial inflammation was analyzed by histopathological analysis and expression of growth associated protein-43 (GAP-43), sensory (SP, CGRP) and autonomic (NPY, VIP, TH) neuropeptides was studied by single and double immunohistochemistry techniques. Results: We observed reduced KSS and increased inflammatory score in synovial membrane of medial knee compartment. A significant increase in GAP-43 [P = 0.001], SP [P = 0.05], CGRP [P = 0.05] and TH [P = 0.05] expression was observed and SP, CGRP and NPY were found to be co-existed predominantly with GAP-43 in synovial membrane collected from medial compared to the lateral knee compartment. Conclusions: Regenerating nerve fibers containing sensory and autonomic neuropeptides are associated with pain and inflammation in knee joint OA.

Hip Joint Osteoarthritis Pain Sources and Control

Hip joint osteoarthritis, a widespread disabling disease with no known cause, produces considerable bouts of intractable pain as a result of multiple disease associated problems. This paper examines some sources of osteoarthritic hip joint pain, a poorly understood topic at best. Presented in three parts are data retrieved from several sources, including animal models. It is concluded that to improve the effectiveness of treatments designed to minimize hip osteoarthritis pain, a better understanding of the diverse origins of hip joint pain, and hip joint neurology, may permit the development of more precise as well as targeted pain strategies.

Treatment of condylar osteophyte in temporomandibular joint osteoarthritis with muscle balance occlusal splint and long-term follow-up:A case report

BACKGROUND Condylar osteophytes,a remodeling form of temporomandibular joint osteoarthritis(TMJ OA),mainly manifest as marginal angular outgrowths of the condyle.Previous researchers have advocated surgical removal of condylar osteophytes.Reports on the effect of occlusal splint on TMJ OA patients’joints have mostly focused on treatment with this splint,which can reduce the absorption of the affected condyle and promote repair and regeneration.However,the effect of the splint on the dissolution of condylar osteophytes has not yet been reported.CASE SUMMARY A 68-year-old female patient suffered from occlusal discomfort with left facial pain for 2 years.Cone beam computed tomography showed a rare osteophyte on top of her left condyle.She was finally diagnosed with TMJ OA.The patient refused surgical treatment and received conservative treatment with a muscle balance occlusal splint.The pain experienced by the patient on the left side of her face was relieved,and her chewing ability recovered after treatment.The osteophyte dissolved,and the condylar cortex remained stable during long-term follow-up observations.CONCLUSION The muscle balance occlusal splint could be a noninvasive means of treating condylar osteophytes in TMJ OA patients.

Usefulness of the acromioclavicular joint cross-sectional area as a diagnostic image parameter of acromioclavicular osteoarthritis

BACKGROUND Acromioclavicular joint(ACJ)space narrowing has been considered to be an important diagnostic image parameter of ACJ osteoarthritis(ACJO).However,the morphology of the ACJ space is irregular because of osteophyte formation,subchondral irregularity,capsular distention,sclerosis,and erosion.Therefore,we created the ACJ cross-sectional area(ACJCSA)as a new diagnostic image parameter to assess the irregular morphologic changes of the ACJ.AIM To hypothesize that the ACJCSA is a new diagnostic image parameter for ACJO.METHODS ACJ samples were obtained from 35 patients with ACJO and 30 healthy individuals who underwent shoulder magnetic resonance(S-MR)imaging that revealed no evidence of ACJO.Oblique coronal,T2-weighted,fat-suppressed SMR images were acquired at the ACJ level from the two groups.We measured the ACJCSA and the ACJ space width(ACJSW)at the ACJ on the S-MR images using our imaging analysis program.The ACJCSA was measured as the cross-sectional area of the ACJ.The ACJSW was measured as the narrowest point between the acromion and the clavicle.RESULTS The average ACJCSA was 39.88±10.60 mm;in the normal group and 18.80±5.13 mm;in the ACJO group.The mean ACJSW was 3.51±0.58 mm in the normal group and 2.02±0.48 mm in the ACJO group.ACJO individuals had significantly lower ACJCSA and ACJSW than the healthy individuals.Receiver operating characteristic curve analyses demonstrated that the most suitable ACJCSA cutoff score was 26.14 mm^(2),with 91.4%sensitivity and 90.0%specificity.CONCLUSION The optimal ACJSW cutoff score was 2.37 mm,with 88.6%sensitivity and 96.7%specificity.Even though both the ACJCSA and ACJSW were significantly associated with ACJO,the ACJCSA was a more sensitive diagnostic image parameter.

A case report:Bilateral atraumatic proximal tibiofibular joint osteoarthritis

Introduction: Proximal tibiofibular joint osteoarthritis is a rare disease most commonly occurring in the presence of either systemic inflammatory conditions or severe knee osteoarthritis. Case Presentation: The authors present a case report of isolated bilateral tibiofibular arthrosis in an otherwise healthy 28-year-old female patient. The patient presented with complaints of lateral knee pain. Radiographs and magnetic resonance imaging (MRI) revealed bilateral tibiofibular joint osteoarthritis. Trauma, repetitive use injury, and rheumatologic causes were excluded. The patient’s pain was initially managed conservatively, but she subsequently underwent tibiofibular arthrodesis for progressive pain symptoms. We review in this report the current literature on tibiofibular joint osteoarthritis and its treatment. Conclusion: Isolated tibiofibular joint osteoarthritis is a rare condition that may progress and requires surgical treatment to achieve optimal clinical outcomes.

Expression changes and clinical significance of TLR-4 and IL-1β in serum and knee joint fluid of patients with knee osteoarthritis

Objective:To investigate the expression changes and clinical significance of Toll-like receptor-4(TLR-4)and interleukin-1β(IL-1β)in the serum and knee joint fluid in patients with knee osteoarthritis(KOA).Methods:From June 2017 to December 2018,220 cases of patients with KOA who were admitted in Department of Orthopedics of the Third Affiliated Hospital of Inner Mongolia Medical University(“our hospital”for short)were selected as the observation group.According to the severity of KOA,they were divided into the mild subgroup(n=98),the moderate subgroup(n=80)and the severe subgroup(n=42).In addition,60 cases of volunteers who received the physical examination in Health Medical Center of our hospital were selected as the control group.The levels of TLR-4 and IL-1βin the serum and knee joint fluid were detected by enzyme-linked immunosorbent assay,in order to analyze the correlation of TLR-4 and IL-1βlevels with the severity of KOA.Results:The levels of TLR-4 and IL-1βin the serum and knee joint fluid of the observation group were significantly higher than those of the control group,and the differences were statistically significant(all p<.05).The levels of TLR-4 and IL-1βin the serum and knee joint fluid of the severe subgroup were significantly higher than those of the mild subgroup and the moderate subgroup,and the levels of TLR-4 and IL-1βin the serum and knee joint fluid of the moderate subgroup were higher than those of the mild group.The differences were statistically significant(all p<.05).The levels of TLR-4 and IL-1βin the serum and knee joint fluid were positively correlated to the severity of KOA(r=.706,.729,.741,.715,all p<.05);in the serum,the level of TLR-4 was positively correlated to the level of IL-1β(r=.720,p<.05);in the joint fluid,the level of TLR-4 was positively correlated to the level of IL-1β(r=.736,p<.05).Conclusions:The levels of TLR-4 and IL-1βin the serum and knee joint fluid of KOA patients are abnormally increased,which is closely related with the severity of KOA.It can be used for clinical prediction,diagnosis and treatment of KOA.

Detection Algorithm of Knee Osteoarthritis Based on Magnetic Resonance Images

Knee osteoarthritis(OA)is a common disease that impairs knee function and causes pain.Currently,studies on the detection of knee OA mainly focus on X-ray images,but X-ray images are insensitive to the changes in knee OA in the early stage.Since magnetic resonance(MR)imaging can observe the early features of knee OA,the knee OA detection algorithm based on MR image is innovatively proposed to judge whether knee OA is suffered.Firstly,the knee MR images are preprocessed before training,including a region of interest clipping,slice selection,and data augmentation.Then the data set was divided by patient-level and the knee OA was classified by the deep transfer learning method based on the DenseNet201 model.The method divides the training process into two stages.The first stage freezes all the base layers and only trains the weights of the embedding neural networks.The second stage unfreezes part of the base layers and trains the unfrozen base layers and the weights of the embedding neural network.In this step,we design a block-by-block fine-tuning strategy for training based on the dense blocks,which improves detection accuracy.We have conducted training experiments with different depth modules,and the experimental results show that gradually adding more dense blocks in the fine-tuning can make the model obtain better detection performance than only training the embedded neural network layer.We achieve an accuracy of 0.921,a sensitivity of 0.960,a precision of 0.885,a specificity of 0.891,an F1-Score of 0.912,and an MCC of 0.836.The comparative experimental results on the OAI-ZIB dataset show that the proposed method outperforms the other detection methods with the accuracy of 92.1%.

Microarray analysis of signalling interactions between inflammation and angiogenesis in subchondral bone in temporomandibular joint osteoarthritis

Inflammation and angiogenesis,the major pathological changes of osteoarthritis(OA),are closely associated with joint pain;however,pertinent signalling interactions within subchondral bone of osteoarthritic joints and potential contribution to the peripheral origin of OA pain remain to be elucidated.Herein we developed a unilateral anterior crossbite mouse model with osteoarthritic changes in the temporomandibular joint.Microarray-based transcriptome analysis,besides quantitative real-time polymerase chain reaction,was performed to identify differentially expressed genes(DEGs).Overall,182 DEGs(fold change≥2,P<0.05)were identified between the control and unilateral anterior crossbite groups:168 were upregulated and 14 were downregulated.On subjecting significant DEGs to enrichment analyses,inflammation and angiogenesis were identified as the most affected.Inflammation-related DEGs were mainly enriched in T cell activation and differentiation and in the mammalian target of rapamycin/nuclear factor-κB/tumour necrosis factor signalling.Furthermore,angiogenesis-related DEGs were mainly enriched in the Gene Ontology terms angiogenesis regulation and vasculature development and in the KEGG pathways of phosphoinositide 3-kinase-protein kinase B/vascular endothelial growth factor/hypoxia-inducible factor 1 signalling.Protein-protein interaction analysis revealed a close interaction between inflammation-and angiogenesis-related DEGs,suggesting that phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta(Pi3kcd),cathelicidin antimicrobial peptide(Camp),C-X-C motif chemokine receptor 4(Cxcr4),and MYB proto-oncogene transcription factor(Myb)play a central role in their interaction.To summarize,our findings reveal that in subchondral bone of osteoarthritic joints,signal interaction is interrelated between inflammation and angiogenesis and associated with the peripheral origin of OA pain;moreover,our data highlight potential targets for the inhibition of OA pain.

Medium-term efficacy of arthroscopic debridement vs conservative treatment for knee osteoarthritis of Kellgren-Lawrence grades I-III

BACKGROUND Arthroscopic debridement is a mature treatment for knee osteoarthritis(KOA).Due to the differences in the research subjects,methods,and efficacy evaluation indexes,there are great differences in the surgical efficacy reported in the literature.AIM To compare the medium-term efficacy of arthroscopic debridement and conservative treatment for KOA of Kellgren-Lawrence grades I-III.METHODS Patients with KOA of Kellgren-Lawrence grades I-III who were admitted to the orthopedic clinic of our hospital from July 2018 to December 2018 and agreed to undergo arthroscopic surgery were included in an arthroscopic debridement group,and those who refused surgical treatment were included in a conservative treatment group.Gender,age,body mass index(BMI),side of KOA,American hospital for special surgery knee score(HSS score)before treatment,visual analogue scale(VAS)score during walking and rest before treatment,conservative treatment content,and surgical procedure were recorded.Outpatient visits were conducted at the 1st,3rd,6th,12th,and 24th mo after treatment in the two groups.The changes of HSS score and VAS score in each group before and after treatment were statistically analyzed,and the differences of HSS score and VAS score in different treatment stages between the two groups were also compared.RESULTS In the conservative treatment group,there were 80 patients with complete followup data,including 20 males and 60 females,aged 58.75±14.66 years old.And in the knee arthroscopic debridement group,there were 98 patients with complete follow-up data,including 24 males and 74 females,aged 59.27±14.48 years old.There was no statistically significant difference in the general data(gender,age,BMI,side of KOA,Kellgren-Lawrence grade distribution,HSS score,and VAS score)between the two groups before treatment.The HSS scores of the conservative treatment group at the 1st,3rd,6th,12th,and 24th mo after treatment were significantly higher than that before treatment(P<0.05).There was no statistical difference in HSS score of the conservative treatment group among the 1st,3rd,6th,12th,and 24th mo(P>0.05).The HSS score of the knee arthroscopic debridement group at the 1st mo after surgery was significantly higher than that before surgery(P<0.05).HSS scores of the knee arthroscopic debridement group at the 3rd,6th,12th,and 24th mo were significantly higher than those before surgery and at the 1st mo after surgery(P<0.05).There were no statistically significant differences in HSS scores at the 3rd,6th,12th,and 24th mo after surgery(P>0.05).HSS scores at the 3rd,6th,12th,and 24th mo were significantly higher in the arthroscopic debridement group than in the conservative treatment group(P<0.05).There was no statistical difference in HSS scores between the two groups before treatment and at the 1st mo of follow-up(P>0.05).VAS scores during walking and rest were significantly decreased in both groups,and the VAS score during rest was significantly lower in the arthroscopic debridement group than in the conservative treatment group,but there was no significant difference in the VAS score during walking between the two groups after treatment.CONCLUSION Compared with conservative treatment,arthroscopic debridement can significantly improve the knee resting pain and knee functional status of patients with KOA of Kellgren-Lawrence grades I-III within 2 years after treatment.

Comparison of Three Experimental Models for Rat Osteoarthritis Induction

Background: Osteoarthritis is a slowly progressive and debilitating disease with high prevalence in adult population. Knee is one of the joints most affected by this disorder. There are several models for animals’ osteoarthritis induction, however it is not identified any paper that compares these techniques. The present study was aimed to define the most appropriate model for rats osteoarthritis induction. Material and Methods: 40 Wistar rats were distributed into 4 groups of 10 animals each: normality group (NG);meniscectomy group (MG);quinolone group (QG) and iodoacetate group (IG). Radiographic images of the rat’s knees were analyzed as well as the amount of chondrocytes in the epiphyseal and articular cartilage. Results: In the radiographic analysis, there was a low correlation between the raters. Regarding the amount of chondrocytes in the epiphyseal cartilage, it was noticed that the IG and QG groups had fewer chondrocytes than NG, in contrast to MG that reported similar results to normality (p > 0.05). There was no significant difference between IG and QG groups (p > 0.05). Regarding the amount of chondrocytes in articular cartilage, it was noticed that the IG group showed fewer chondrocytes than NG (p 0.05). There was no significant difference between QG and MG groups (p > 0.05). Conclusion: Intraarticular injection of iodoacetate in rats is the model with greatest effect on reduction of chondrocytes amount.

Distraction arthroplasty in osteoarthritis of the foot and ankle

Post-traumatic osteoarthritis(PTOA)is a complex and painful problem in the foot and ankle.Ninety percent of osteoarthritis cases in the foot and ankle can be classified as post-traumatic.PTOA can affect any of the 33 joints in the foot and the ankle.Distraction arthroplasty is a method for treatment of early arthritic joints without fusing or replacing them and its effectiveness has been well documented.The purpose of this case series is to present our successful experiences and positive results using distraction arthroplasty to treat PTOA in the ankle,subtalar,first metatarsophalangeal,and second tarsometatarsal joints,and to present distraction arthroplasty as a viable alternative to invasive joint sacrificing procedures such as arthrodesis or arthroplasty.Distraction Arthroplasty effectively and safely treats PTOA and improves the stability of joints in the Foot and Ankle.Additionally,the use of bone marrow aspirate concentrate as an adjuvant can improve the long-term functional and structural outcomes of the joint,and can prolong the need for further,more aggressive surgical interventions such as fusion or arthroplasty.
