ABSTRACT

Objective:To evaluate the early clinical outcomes of 5G remote telesupervised robot assisted total hip arthroplasty in the treatment of Kaschin-Beck disease with hip problems in Tibet through retrospective analysis of the hip surgery cohort.Methods:According to the operation procedure, 55 Kaschin-Beck disease patients (59 hips) undergoing total hip arthroplasty from November 2020 to November 2021 in the Karub District People's Hospital in Qamdo were divided into the conventional THA group (cTHA) and the 5G remote telesupervised robot assisted THA group (rTHA). Two of them underwent cTHA on both hips, while the other two patients underwent cTHA and rTHA separately of each hip, and the rest underwent single hip surgeries. In the cTHA group, there were 30 patients (32 hips), 16 males (17 hips) and 14 females (15 hips), aged 56.56±9.33 years (range, 36-76 years); In the rTHA group, there were 27 patients (27 hips), 10 males and 17 females, aged 55.41±10.90 years (range, 24 to 79 years). Before operation, Harris hip score was recorded and femoral offset (FO) and leg length difference (LLD) were measured via X-ray images. The operation time was collected during the hip surgery and an average network delay of 172.28±36.58 ms and a 1.08% data packet loss ratio is obtained during telesupervision. 24 hours post-operatively, the FO and LLD were both measured via the X-ray images, as well as the inclination and anteversion of the acetabular cup. The Harris scores were collected in the following up. The operation time, FO, LLD, inclination, anteversion and Harris score were compared between the two groups.Results:All cases in both groups were followed up for an average of 9.39±2.43 months (range, 6-19 months). There were no significant differences in pre-operative FO and LLD, preoperative Harris scores or average follow-up time between the two groups. The operation time in rTHA group was 126.41±12.78 min, which is significantly longer than the time 88.81±8.83 min in cTHA group ( t=13.31, P<0.001). After operation, the FO was significantly increased and the LLD was significantly decreased ( P<0.05). The postoperative LLD was 0.63±0.65 cm in the robot group and 1.15±0.71 cm in the conventional group, the difference was statistically significant ( t=2.88, P=0.006). However, there was no significant difference in the FO, inclination and anteversion between the two groups post-operatively ( P>0.05). The Harris scores of both groups were significantly improved compared with that before the operation. Additionally, the Harris score of the two groups was significantly higher than that before surgery, and the postoperative Harris score of the rTHA was 69.00±12.33 higher than that of the cTHA (62.31±11.87), with statistical significance ( t=2.12, P=0.039). The ratio of excellence of Harris score was 19% (5/27) in the rTHA and 9% (3/32) in the cTHA, with no significant difference between groups (χ 2=1.05, P=0.522). Conclusion:Compared to conventional surgery, 5G remote telesupervised robot assisted total hip arthroplasty has more advantages in improving the joint functions in the treatment of hip problems caused by Kashin-beck disease in Tibet Autonomous Region, and facilitates more accurate adjustment of lower limb length difference, even though it consumes more operation time.

ABSTRACT

Osteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.

ABSTRACT

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

ABSTRACT

Objective:To evaluate the long-term effect of structured patient education and exercise therapy for knee osteoarthritis (KOA).Methods:Prospective cohort study, 162 patients with KOA were consecutively recruited from May 2016 to December 2019 to receive structured patient education and exercise therapy and were followed up 3 years after the recruitment. All the patients received two 1-hour educational courses and exercise therapy twice per week for six weeks under the supervision of physicians or physical therapists. Knee injury and osteoarthritis score (KOOS), visual analog score of pain (VAS), intermittent and constant OA pain (ICOAP), self-efficacy for arthritis were queried at 3-month and 36-month follow-up visit. We fitted linear mixed-effects models to examine the difference in scores between baseline and 3-month and 36-month visits.Results:109(67.3%) patients finished both 3-month and 36-month follow-up visits. The KOOS pain score increased from 70.8±1.7 at baseline to 79.7±1.8 at 36 months ( P<0.05). The KOOS symptom score increased from 66.8±2.0 at baseline to 74.9±2.1 at 36 months ( P<0.05). The KOOS daily function score increased from 81.7±1.4 at baseline to 87.0±1.5 at 36 months ( P<0.05). KOOS motor function score increased from 47.4±2.8 at baseline to 55.0±2.9 at 36 months ( P<0.05). The quality of life score of KOOS increased from 46.6±2.1 at baseline to 63.5±2.2 at 36 months ( P<0.05). Compared with the baseline data, there were statistically significant improvements in all subscales of KOOS in 36 months after exercise therapy intervention ( F=14.548, 8.102, 11.394, 5.687 and25.942, P<0.05). VAS pain score of left knee, VAS pain score of right knee, ICOAP score, self-efficacy pain score and other symptoms were also significantly improved ( F=17.643, 26.791, 8.290, 4.052 and 3.654, P<0.05). Conclusion:Structured patient education and exercise therapy are effective in improving knee pain and function as well as self-efficacy until as long as 36 months.

ABSTRACT

Objective:To culture UC-MSCs with 3D TableTrix TM stem cell microcarrier and further evaluate the effects on cartilage defect of knee joint in rabbit model. Methods:UC-MSCs were cultured in 3D TableTrix TM system for 7 d. The cell viability was evaluated and characteristics of UC-MSCs were identified. The safety of 3D 3D TableTrix TM system was further evaluated by subcutaneous implantation in nude mice. Twelve New Zealand white rabbits were randomly divided into control group and experimental group. The experimental group was placed in 3D TableTrix TM with UC-MSCs. At 3 and 6 months after the operation, the samples were taken for general observation, HE, toluidine blue, Masson staining for comparative observation. According to the International Cartilage Repair Society (ICRs), general evaluation and histological score was evaluated quantitatively. Results:The UC-MSCs survived well in 3D TableTrix TM system. There was no dead cell with dead/live staining after 7 d culture. UC-MSCs proliferated in 3D TableTrix TM system. After digestion, the UC-MSCs were identified to maintain the characteristics of MSCs. After 28 d of subcutaneous implantation in nude mice, agglomerations were formed and covered with fibrous membrane. HE staining showed that the 3D TableTrix TM scaffold structure was complete and neovascularized. In vivo study, 3D TableTrix TM was used to fill the cartilage defect. At 3 and 6 months after operation, the effects on cartilage repair in the experimental group was better than that in the control group. The overall score of ICRS (3 month, 8.50±0.58 vs 4.50±0.58; 6 months, 11.25±0.96 vs 8.75±0.50, P<0.05) and histological score of the experimental group were higher than that of the control group (3 month, 11.00±2.16 vs 5.25±0.50; 6 month 17.00±0.82 vs 11.25±0.96, P<0.05). Conclusions:3D TableTrix TM microcarrier provides an ideal microenvironment for stem cell culture, and that can be used in the treatment of cartilage defects.

ABSTRACT

Objective:To investigate the orthopedists' cognition on Chinese Osteoarthritis Guideline (2018 Edition).Methods:Questionnaire about Chinese Osteoarthritis Guideline (2018 Edition) was developed and sent to orthopedists via an invitation link to fill out after authorization from Chinese Osteoarthritis Association. The content of the questionnaire included the basic personal information of the physician, the awareness rate of the guidelines, the evaluation of the guidelines, and its application effects. The survey duration was from September 2019 to December 2019. Multivariate logistic regression and linear regression analysis were performed for the guideline awareness rate and comprehensive score, respectively.Results:A total of 628 physicians completed the questionnaire, of which 623 of 628 (99.2%) were available. About 72.4% of the orthopedists knew the guideline. The awareness rate was statistically related to the education of the physicians ( P<0.05). Respondents' overall score for the guideline was 8.39 with methodological score 8.28. A total of 41.2% of orthopedists thought that the guideline was very good compared with the European and American guidelines, and the clinical problem coverage rate was 78.6%. There is a statistically significant difference in the appraisal of the recommendations ( χ2=138.9, P<0.05) . More than 40% of orthopedists believed that the guidelines were of great help to orthopedists and patients, and that the guide could be promoted to the primary hospitals. Conclusion:After one year publication of Chinese Osteoarthritis Guideline (2018 Edition), most orthopedists have understood the present guideline and applied recommendations in clinical practice. However, the guideline need to be further promoted and disseminated in the future.

ABSTRACT

At present, several clinical practice guidelines for osteoarthritis have been developed. Although contradictions about some recommendations are still in dispute, large number of clinical practice guidelines recommended core treatments, namely education, weight loss and exercise therapy. Thus, the diagnosis and treatment of primary osteoarthritis should focus on the above three treatments. However, we have to develop the clinical practice guidelines for osteoarthritis in primary hospital, based on the characteristics of osteoarthritis in China, the burden of disease, the health literacy of patients and the clinical decision-making of diagnosis and treatment of primary osteoarthritis in primary medical care.We suggest to formulate guidelines for the diagnosis and treatment of osteoarthritis in primary medical care to regulate primary interventions.

ABSTRACT

BACKGROUND: Osteoarthritis (OA) is a kind of chronic bone and joint disease which seriously endangers human health. Cell therapy for OA has aroused widespread concern and gotten rapid development in recent years. Umbilical cord-derived mesenchymal stem cells (UC-MSCs) have the advantages of easy amplification and differentiation, anti-inflammation and recruiting function such as MSCs from other sources. Furthermore, UC-MSCs are young cells that have large quantity, no ethical problems, high proliferative potential and pluripotent differentiation. UC-MSCs have been the most commonly used seed cells in clinical cell therapy. OBJECTIVE: To evaluate the efficacy and safety of UC-MSCs in the treatment of human knee OA to provide theoretical and clinical basis for stem cell therapy of OA. METHODS: The trail will be completed in Arthritis Clinic & Research Center, Beijing, China. Participants will be recruited according to established inclusion/exclusion criteria after obtaining the informed consent and the approval of the Ethics Committee (the first and second parts of the trial have been registered (https://register.clinicaltrials.gov/), with the identifier No. NCT03357770 and NCT03358654, and the third part will be carried out according to the conclusion of the first and second parts). The clinical trial will be divided into three parts: in the first part three groups will be recruited. Each group will contain three participants. The three groups of participants will be treated with high, medium and low dose of MSCs, respectively. Participants will be followed up to evaluate dose-limiting toxicity so as to determine the maximum tolerated dose. The second part will be a single-arm clinical trial. Nine participants will be recruited. The injection dose will be the maximum tolerated dose determined in the first part. Participants will be followed up to evaluate the safety and efficacy of the treatment. The third part will be a randomized controlled trial. Participants will be randomly divided into two groups (n=7 per group) and treated with MSCs and hyaluronic acid, respectively. During the trial, evaluators, participants and interveners will be unaware of grouping information and interventions. Participants will be followed up at designed time points after treatment to evaluate the safety and efficacy of the intervention. The trial will be terminated if there are unexplained local and systemic symptoms or death according to the NCI-CTCAE criteria. EXPECTED RESULTS: With reference to the previous literature, the knee pain will be relieved, the score of knee joint function will increase, and the cartilage defect area will decrease on MRI at 1-2 years after the intervention. The trail is expected to spend 3 years and 6 months.

ABSTRACT

Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.

ABSTRACT

To investigate the combined effects of indomethacin and oxaliplatin on expressions of epidermal growth factor receptor [EGFR], E-cadherin [E-cad], intercellular adhesion molecule-1 [ICAM-1] and CD44v6 related to lymph node metastasis of human lung cancer cell lines. Human lung adenocarcinoma A549 cells were inoculated subcutaneously into the left armpit of nude mice to establish human lung cancer xenografts. The mice were randomly divided into control group, indomethacin group, oxaliplatin group and combination therapy group, which were treated with sterile distilled water, indomethacin, oxaliplatin and indomethacin combined with oxaliplatin, respectively. After 42 days, the mice were sacrificed. The immunohistochemistry and reverse transcription polymerase chain reaction were used to detect the expressions of EGFR, E-cad, ICAM-1 and CD44v6 in tumor tissues. Compared to control group, the protein and mRNA expressions of EGFR, ICAM-1 and CD44v6 in the indomethacin, oxaliplatin, and combination therapy groups were significantly reduced [P<0.05] and the protein and mRNA expressions of E-cad expression were significantly increased [P<0.05]. Compared to indomethacin group and oxaliplatin group, the protein and mRNA expressions of EGFR, ICAM-1 and CD44v6 in combination therapy groups were significantly reduced [P<0.05], and the protein and mRNA expressions of E-cad expression were significantly increased [P<0.05]. There was no significant difference between indomethacin and oxaliplatin groups. Indomethacin and oxaliplatin have synergistic effect on expressions of lymph node metastasis related factors in lung cancer cell lines
