The Top 100 Most-Cited Articles on Arthroscopy: Most Popular Topic Is Rotator Cuff Rather Than Cartilage in the Last 5 Years.

Arthroscopy 2021 Feb 2. Epub 2021 Feb 2.

Orthopaedic Department, The Second Xiangya Hospital of Central South University, Changsha, Hunan Province, China. Electronic address:

Purpose: To highlight the characteristics of the 100 most-cited articles on arthroscopy and provide the variation trend of citation rate among the top 25 articles in the past 9 years. We further analyzed the topics of interest in the past or currently.

Methods: The Thomson ISI Web of Science database was used to identify arthroscopy-related articles that were published from 1950 to March 31, 2020. The 100 most-cited articles were selected for further analysis. In addition, author key words of the articles that published in the recent 5 years were further analyzed.

Results: Mean of citations was 433.59 ± 400.73. The publication year ranged from 1980 to 2013. Most articles were focused on cartilage lesions and treatments (26%). A large proportion of articles were published in the 2000s (61%). Arthroscopy-the Journal of Arthroscopic and Related Surgery (23%) was the most popular journal. One half of the articles originated from the United States. The most prolific institution and first author were the Steadman Philippon Research Institute (5%) and Marc J. Philippon (4%), respectively. Most of the articles were Level IV evidence (33%). The citation rate increased by 131% from the previous top 25 articles published in 2011. A growth trend can be seen in the citation density over time. "Shoulder" (occurrences = 535) was the most used joint key word and "rotator cuff" (342) was the most used key word of research objective in the last 5 years, whereas "cartilage" only occurred 262 times.

Conclusions: Based on bibliometric analysis of the 100 most-cited articles on arthroscopy combined with network analysis of the whole articles that published in the recent 5 years, the topic of most interest in the recent 5 years was rotator cuff rather than cartilage. The number of citations among the 25 most-cited articles is growing rapidly and has at least doubled in size on average in the past 9 years. Citation density among the 100 most-cited articles on arthroscopy has seen a growth trend.

Clinical Relevance: This article clarifies the characteristics of the 100 most-cited papers and provides guidance on the topics of interest in the past or currently as a roadmap for future research on arthroscopy.

Classification of four distinct osteoarthritis subtypes with a knee joint tissue transcriptome atlas.

Bone Res 2020 Nov 12;8(1):38. Epub 2020 Nov 12.

Dr. Li Dak Sum & Yip Yio Chin Center for Stem Cells and Regenerative Medicine, and Department of Orthopedic Surgery of the Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, China.

The limited molecular classifications and disease signatures of osteoarthritis (OA) impede the development of prediagnosis and targeted therapeutics for OA patients. To classify and understand the subtypes of OA, we collected three types of tissue including cartilage, subchondral bone, and synovium from multiple clinical centers and constructed an extensive transcriptome atlas of OA patients. By applying unsupervised clustering analysis to the cartilage transcriptome, OA patients were classified into four subtypes with distinct molecular signatures: a glycosaminoglycan metabolic disorder subtype (C1), a collagen metabolic disorder subtype (C2), an activated sensory neuron subtype (C3), and an inflammation subtype (C4). Through ligand-receptor crosstalk analysis of the three knee tissue types, we linked molecular functions with the clinical symptoms of different OA subtypes. For example, the Gene Ontology functional term of vasculature development was enriched in the subchondral bone-cartilage crosstalk of C2 and the cartilage-subchondral bone crosstalk of C4, which might lead to severe osteophytes in C2 patients and apparent joint space narrowing in C4 patients. Based on the marker genes of the four OA subtypes identified in this study, we modeled OA subtypes with two independent published RNA-seq datasets through random forest classification. The findings of this work contradicted traditional OA diagnosis by medical imaging and revealed distinct molecular subtypes in knee OA patients, which may allow for precise diagnosis and treatment of OA.

The differences of clinical characteristics and outcomes between imported and local patients of COVID-19 in Hunan: a two-center retrospective study.

Respir Res 2020 Nov 26;21(1):313. Epub 2020 Nov 26.

Department of Radiology, The Second Xiangya Hospital, Central South University, Changsha, 410011, Hunan, China.

Background: The clinical characteristics and outcomes of the 2019 novel coronavirus (COVID-19) pneumonia are different in Hubei compared to other regions in China. But there are few comparative studies on the differences between imported and local patients which may provide information of the different courses of the virus after transmission.

Methods: We investigated 169 cases of COVID-19 pneumonia in two centers in Hunan Province, and divided them into two groups according to epidemiological history, "imported patients" refers to patient with a clear history of travel in Wuhan within 14 days before onset, and " local patients" refers to local resident without a recent history of travel in Wuhan, aiming to analyze the difference in clinical characteristics and outcomes between the two groups. All the epidemiological, clinical, imaging, and laboratory data were analyzed and contrasted.

Results: The incidence of fever on admission in imported patients was significantly higher than local patients. There was a significantly higher proportion of abnormal pulmonary signs, hypokalemia, hyponatremia, prolonged PT, elevated D-dimer and elevated blood glucose in imported patients. Compared with local patients, the proportion using antibiotics, glucocorticoids and gamma globulin were significantly higher in imported patients. The moderate type was more common in local patients, and the severe type were more frequent in imported patients. In addition, the median duration of viral clearance was longer in imported patients.

Conclusions: In summary, we found that imported cases were more likely to develop into severe cases, compared with local patients and required more powerful treatments. Trial registration Registered 21st March 2020, and this study has been approved by the Medical Ethics Committee (Approved Number. 2020017).

Fixed- versus mobile-bearing unicompartmental knee arthroplasty: a meta-analysis.

Sci Rep 2020 11 5;10(1):19075. Epub 2020 Nov 5.

Department of Orthopaedics, The Second Xiangya Hospital, Central South University, No.139 Middle Renmin Road, Changsha, Hunan, 410011, People's Republic of China.

Unicompartmental knee arthroplasty (UKA) can be either a fixed bearing (FB) or a mobile bearing (MB) construct with controversy as to which design is superior. This question is addressed with a systematic review and meta-analysis. A literature search was performed using PubMed, Embase and the Cochrane Library. Studies were reviewed according to the inclusion and exclusion criteria developed in advance. We compared the differences in clinical and radiological outcomes between the FB and MB UKAs. Analyses were performed with the Review Manager and STATA software. A total of 17 studies involving 2612 knees were included. No significant differences were presented between the FB and MB prostheses in clinical and radiological outcomes. However, it was evident that there were differences in the modes and timing of the failures, bearing dislocation led to earlier failures in the MB prosthesis, while the FB prosthesis failed later due to polyethylene wear. There was no evidence of publication bias using the incidence of revisions. There is no significant difference between the FB and MB UKAs; however, there are differences in the modes and timing of failures.

Oxygen embolism after hydrogen peroxide irrigation during hip arthroscopy: a case report.

BMC Musculoskelet Disord 2020 Jan 30;21(1):58. Epub 2020 Jan 30.

Department of Orthopaedics, the Second Xiangya Hospital, Central South University, No.139 Middle Renmin Road, Changsha, 410011, Hunan, China.

Background: Hydrogen peroxide has been widely used in Orthopaedics including Orthopaedic oncology, trauma and joint surgeries. However, we encountered an oxygen embolism and myoglobinuria after hydrogen peroxide was used to irrigate a septic hip arthroscopically.

Case Presentation: A 61-year-old male patient with right hip septic arthritis underwent an arthroscopic hip washout and debridement. During the operation, the surgeon used 100 ml of 3% hydrogen peroxide to irrigate the joint cavity. Two minutes after irrigation, there was a transient decrease in oxygen saturation, heart rate and blood pressure, with significant subcutaneous emphysema around the wound. Concentrated urine was drained out 8 h after operation which resolved the following day. Post-operatively, the patient was managed in the intensive care unit for a pulmonary embolism and discharged without further complications.

Conclusion: Medical staff should be aware of the risk of oxygen embolism and be extremely careful when using hydrogen peroxide in patient care. Oxygen embolism following hydrogen peroxide use is rare, however, once encountered, it may bring serious consequences. Therefore, the use of hydrogen peroxide in closed spaces or arthroscopic procedures should be discontinued.

The top 100 most cited articles on total hip arthroplasty: a bibliometric analysis.

J Orthop Surg Res 2019 Dec 4;14(1):412. Epub 2019 Dec 4.

Orthopaedic department, The Second Xiangya hospital of Central South University, Changsha, Hunan Province, China.

Background: Over the past few decades, more and more articles about total hip arthroplasty have been published. We noticed, however, little is known about the characteristics and qualities of these studies.

Methods: The databases of Web of Science Core Collection, BIOSIS Citation Index, MEDLINE, etc. were utilized for the identification of articles published from 1990 to May 2019. Total hip arthroplasty-related articles were identified, and the 100 most cited articles were selected for subsequent analysis of citation count, citation density (citations/article age), authorship, theme, geographic distribution, time-related flux, level of evidence, and network analysis.

Results: The selected 100 articles were published mainly in the 1990s (46%) and 2000s (47%) with almost equal amount. Citations per article ranged from 994 to 191. Leading countries were the USA followed by Canada, England, and Sweden, all located in North America and Western Europe. The most highlighted study themes were postoperative thrombosis and surgical methods and materials. The most common level of evidence was level III (35%). The network analysis connoted that radiography, acetabulum, reoperation, and bone cement had a high degree of centrality in the 1990s, while cement had a high degree of centrality in the 2000s and 2010s.

Conclusions: The time, area, and theme distribution of the top 100 most cited articles in the total hip arthroplasty have been thoroughly analyzed. It is noticeable that postoperative thromboembolism currently plays a major role in the field of total hip arthroplasty researches. However, most of them focus on the effectiveness of different treatments and drugs; little is known about its underlying mechanisms and influencing factors.

Twin defects engineered Pd cocatalyst on CN nanosheets for enhanced photocatalytic performance in CO reduction reaction.

Nanotechnology 2017 Dec;28(48):484003

Key Laboratory of the Ministry of Education for Advanced Catalysis Materials, College of Chemistry and Life Sciences, Zhejiang Normal University, Jinhua, Zhejiang, 321004, People's Republic of China.

Photocatalytic conversion of CO to value-added chemicals, a potential route to addressing the depletion of fossil fuels and anthropogenic climate change, is greatly limited by the low-efficient semiconductor photocatalyst. The integration of cocatalyst with light-harvesting semiconductor is a promising approach to enhancing the photocatalytic performance in CO reduction reaction. The enhancement is greatly determined by the catalytic active sites on the surface of cocatalyst. Herein, we demonstrate that the photocatalytic performance in the CO reduction reaction is greatly promoted by twin defects engineered Pd cocatalyst. In this work, Pd nanoicosahedrons with twin defects were in situ grown on CN nanosheets, which effectively improve the photocatalytic performance in reduction of CO to CO and CH in comparison with Pd nanotetrahedrons without twin defects. It is proposed that the twin boundary (TB) terminations on the surface of Pd cocatalysts are highly catalytic active sites for CO reduction reaction. Based on the proposed mechanism, the photocatalytic activity and selectivity in CO reduction were further advanced through reducing the size of Pd icosahedral cocatalyst resulted from the increased surface density of TB terminations. The defect engineering on the surface of cocatalyst represents a novel route in realizing high-performance photocatalytic applications.

Generalized-stacking-fault energy and twin-boundary energy of hexagonal close-packed Au: A first-principles calculation.

Sci Rep 2015 May 22;5:10213. Epub 2015 May 22.

Key Laboratory of Automobile Materials of Ministry of Education &School of Materials Science and Engineering, Nanling Campus, Jilin University, No. 5988 Renmin Street, Changchun 130025, PR China.

Although solid Au is usually most stable as a face-centered cubic (fcc) structure, pure hexagonal close-packed (hcp) Au has been successfully fabricated recently. However, the phase stability and mechanical property of this new material are unclear, which may restrict its further applications. Here we present the evidence that hcp → fcc phase transformation can proceed easily in Au by first-principles calculations. The extremely low generalized-stacking-fault (GSF) energy in the basal slip system implies a great tendency to form basal stacking faults, which opens the door to phase transformation from hcp to fcc. Moreover, the Au lattice extends slightly within the superficial layers due to the self-assembly of alkanethiolate species on hcp Au (0001) surface, which may also contribute to the hcp → fcc phase transformation. Compared with hcp Mg, the GSF energies for non-basal slip systems and the twin-boundary (TB) energies for and twins are larger in hcp Au, which indicates the more difficulty in generating non-basal stacking faults and twins. The findings provide new insights for understanding the nature of the hcp → fcc phase transformation and guide the experiments of fabricating and developing materials with new structures.

Hydrogen-rich saline attenuates ischemia-reperfusion injury in skeletal muscle.

J Surg Res 2015 Apr 15;194(2):471-480. Epub 2014 Dec 15.

Department of Naval Medicine, Second Military Medical University, Shanghai, China.

Background: To investigate the potential beneficial effect of hydrogen-rich saline (HRS) in ischemia-reperfusion (IR) injury of skeletal muscle.

Methods: Three experimental groups were established in male Sprague-Dawley rats: (1) sham group, (2) IR with normal saline group, (3) and IR with HRS group. A rat model of skeletal muscle IR injury was induced by 3-h tourniquet occlusion on its left hind limb and 4-h reperfusion. Normal saline and HRS (1.0 mL/100 g) were administered intraperitoneally at 10 min before reperfusion, respectively. Muscle and serum samples were analyzed for detecting the levels of myeloperoxidase (MPO), superoxide dismutase (SOD), malondialdehyde (MDA), and hydroxyl radical (•OH). Muscle samples were assessed by wet/dry rate, hematoxylin and eosin histologic assessment, Bcl2, Bax, cytochrome C, LC3B, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling, and electron microscopy.

Results: The wet/dry ratio increased significantly in the IR group (P < 0.01 compared with that in the sham group) and decreased significantly in IR with HRS groups (4.12 ± 0.14 versus 4.12 ± 0.14, P < 0.01 compared with that in the IR group). Muscle tissues and serum of the IR group had significantly increased levels of MPO, MDA, •OH content, and decreased SOD activities compared with the sham group (P < 0.01). The activity of SOD in the IR with HRS group was greatly elevated compared with that in the IR group (295.028 ± 9.288 versus 249.190 ± 5.450 in muscle tissues; 91.627 ± 2.604 versus 73.4045 ± 6.487 in serum; P < 0.01), whereas the levels of MPO, MDA, and •OH content were clearly reduced (MPO: 0.5649 ± 0.0724 versus 1.0984 ± 0.0824 in muscle tissues; 0.7257 ± 0.1232 versus 1.3147 ± 0.0531 in serum. MDA: 4.457 ± 0.650 versus 7.107 ± 0.597 in muscle tissues; 2.531 ± 0.434 versus 4.626 ± 0.237 in serum. •OH: 16.451 ± 0.806 versus 19.871 ± 0.594 in muscle tissues; 500.212 ± 7.387 versus 621.352 ± 7.591 in serum, P < 0.01). The integrated optical density of positive amethyst staining increased significantly in the IR group (P < 0.01 compared with that in the sham group) and decreased significantly in IR with HRS group (928.79 ± 234.537 versus 3005.972 ± 83.567, P < 0.01 compared with that in the IR group). Muscle tissues of the IR group had significantly increased levels of Bax, cytochrome C, LC3B content, and decreased Bcl2 activities compared with those in the sham group (P < 0.01). The activity of Bcl2 in the IR with HRS group was greatly elevated compared with that in the IR group (0.2635 ± 0.0704 versus 0.1242 ± 0.0662; P < 0.01), whereas the levels of Bax, cytochrome C, and LC3B content were clearly reduced (Bax: 0.3103 ± 0.0506 versus 0.5122 ± 0.0148; cytochrome C: 0.4194 ± 0.1116 versus 0.8127 ± 0.0166; LC3B: 0.5884 ± 0.0604 versus 1.3758 ± 0.0319; respectively, P < 0.01).

Conclusions: HRS seems to be effective in attenuating IR injury in skeletal muscle via its antioxidant, anti-apoptosis, and anti-autophagy effect.

Bilaterally primary cementless total hip arthroplasty in patients with ankylosing spondylitis.

BMC Musculoskelet Disord 2014 Oct 11;15:344. Epub 2014 Oct 11.

Department of Orthopaedics, The Second Xiangya Hospital, Central South University, Changsha, Hunan 410011, P R China.

Background: The purpose of this study was to document the clinical and radiographic results of a consecutive series of patients with ankylosing spondylitis (AS) who had undergone bilaterally primary THA using non-cemented components.

Methods: Twenty-six hips of 13 patients with bilateral ankylosis of the hip caused by AS were converted to THA from January 2000 to January 2008. The mean age of the patients was 33.7 years (range, 22-57 years). There were 11 males and 2 females. All the patients had bilateral bony ankylosis with 0° range of motion. The average Harris Hip Scores (HSS) was 22.1 (10-38).

Results: At a mean follow-up of 128.4 months, the mean HSS at the latest follow-up examination was 91.7 points (range, 75-98 points). All the patients reported marked relief of painful symptoms. Three (11.5%) of the 26 hips were outside the Lewinnek acetabular cup inclination safe range, and 5 (19.2%) of the 26 hips were outside the Lewinnek acetabular cup anteversion safe range. The probability of survival of the prostheses was 100% at 5 years and 92.3% at 10 years, but it dropped sharply to 73.1% at 13 years.

Conclusion: Cementless THA is a worthwhile treatment for the osseous ankylosed hip joint caused by AS. Newfound mobility, maneuverability, and improved ability to sit comfortably were the outcomes that alleviated the patients' daunted morale. However, the technically demanding nature of the procedure should not be underestimated.

[Curative effect of arthroscopic suture anchor fixation on shoulder bankart injury].

Zhong Nan Da Xue Xue Bao Yi Xue Ban 2013 Mar;38(3):268-73

Department of Orthopedics, Second Xiangya Hospital, Central South University, Changsha 410011, China.

Objective: To determine the curative effect of arthroscopic suture anchor fixation on shoulder bankart injury.

Methods: Sixteen patients with shoulder recurrent dislocation and diagnosed bankart injury were treated with suture anchor fixed by shoulder arthroscopy. Both shoulders of the patients had X-ray, MRI, physical examination before the operation. Suture anchors were used to fix the lesion labrum by shoulder arthroscopy. University of California at Los Angeles (UCLA) score and visual analogue scale (VAS) score were adopted for the final evaluation at the latest follow-up.

Results: All patients were followed for a period of 25 (7-68) months. At the latest follow-up, no redislocation and instability occured. The pre- and post-operation UCLA score was (20.8 ± 0.8) vs (32.9 ± 1.5), excellent in 6, good in 10, with no poor score, while the pre- and post-operation VAS score was (3.3 ± 0.8) vs (0.6 ± 0.5).

Conclusion: Suture anchor fixation guided by arthroscopy is good for bankart injury caused by recurrent shoulder dislocation, which has many advantages, such as mini-invasion, rapid recovery and a satisfactory outcome in function and motion.

[Treatment of delayed popliteal artery trauma of knees].

Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi 2007 Jul;21(7):685-7

Department of Orthopaedics, the Second Xiangya Hospital, Central South University, Changsha Hunan, 410011, PR China.

Objective: To summarize the experience in treatment and diagnosis of popliteal artery trauma and to determine the factors for amputation.

Methods: From February 1995 to January 2006, 28 patients with popliteal artery trauma were treated. The disease course was more than 8 hours. Of them, there were 25 males and 3 females, aging from 3 to 53 years. Trauma was caused by traffic accident in 12 cases, by falling from height in 3 cases, by firearm in 2 cases, by sharp instruments in 3 cases, by strangulation in 2 cases and by others in 6 cases. No arteriopalmus or weak arteriopalmus were observed in 18 cases and in 8 cases respectively. Popliteal artery exposure or active bleeding was seen in 2 cases; the popliteal arteries were examined by operation in 8 cases; color ultrasound Doppler flow imaging showed color flood flow signals were through popliteal artery and its branches in 20 cases. Defect size of popliteal artery was less than 5 cm in 7 cases and more than 5 cm in 9 cases. End to end anastomosis reconstruction by saphenous vein graft and direct suture was performed in 16 cases and ampulation in 12 cases. The time of the revascularization of the leg was 8-150 hours (mean 31. 8 hours).

Results: All patients were followed up 6 months to 11 years with an average of 4.2 years. In 16 cases given end to end anastomosis reconstruction, 15 cases achieved revascularization and limb survival; lower limb function restored to normal within 1 year in 12 cases; foot drop and ankle joint contracture occurred in 3 cases and the survival rate of limbs was 94%. Amputation was given in 12 of 28 cases because of severe trauma. The rate of amputation was 43% and the rate of disability was 54%.

Conclusion: Popliteal artery trauma should be treated as soon as the diagnosis is made. If the revascularization is more than 8 hours or circulatory compensation is not complete, it will affect the leg survival. Delayed diagnosis and severe traumas are the cause of high rate of amputation in popliteal artery trauma.
