11月30日至12月5日，柏林馬丁·路德醫院業務院長、骨科與創傷外科主任，德國膝關節學會前任主席、德語區國家骨科與創傷外科運動醫學學會德國分會副主席Petersen教授，從柏林飛抵廣州，在廣東省中醫院運動醫學科進行了為期一周的客座教授訪問。在這一周的時間里，Petersen教授與楊偉毅主任及團隊共同完成多臺手術，圍繞眾多膝關節外科臨床熱點展開手術示教與技術討論。他與團隊長時間交流病例思路、手術策略、術后康復理念，以開放坦誠的方式分享來自德國臨床一線的真實經驗。周五，他又作為特邀國際專家出席國家骨科醫學中心“保膝中國行”廣州站并授課。這次訪問，對我們而言意義遠遠不止一周的學術交流，而是一次歷經六年、跨越疫情與地域的合作累積的再延伸。Petersen教授與我們相識于2020年1月，那是國際交流驟然停擺的時期。全球的學術會議被迫按下暫停鍵，但在最艱難的時刻，他卻反其道而行，主動發起全線上的國際膝關節日，將疫情阻斷的距離變成線上連通的橋梁。連續三年，仁醫醫療作為中國唯一協辦方，在全國10座城市、12家醫院設立分會場，同步直播學術內容，讓中國醫生在疫情中依然有機會與世界同行。三年間，共有 45 位中國醫生站上國際講臺，累計觀看人數超過 57 萬人次，這不僅是一次交流，更是一次彼此堅定的陪伴。六年來的合作從未間斷，無論外界環境如何變化。在臨床教育方面，Petersen教授始終保持對中國醫院、中國醫生的高度投入。他先后接收 7 位中國訪學醫生進入他的團隊，帶他們進入手術間、門診、查房，讓中國青年醫生能夠直接在德國最成熟的臨床體系中學習。他不僅教技術，更帶人。他會邀請訪學醫生參加聚會，帶他們到家里做客，幫助他們融入陌生的文化環境。從專業到生活，他都盡力讓每一位年輕醫生感到被支持、被重視、被鼓勵。這種真誠的態度，也體現在他對中國博士生培養的持續支持中。2025年，山西醫科大學葛以洲醫生在他的指導下正式開始德國臨床醫學博士的學習。2026 年，他將迎來來自汕頭大學與漳州的兩位新博士生。對每一位中國學生，他都投入實打實的時間與資源，為他們創造真正有助成長的科研與臨床條件。這份對醫生成長的熱情，也貫穿于他在歐洲推動的教育事業。2012 年，他與志同道合的專家共同創立德國膝關節學會，一個從十幾人起步，如今已發展為超過1300名膝關節外科醫生的專業學會。他組織大量面向青年醫生的培訓課程，并牽頭發起 STOP-X 計劃，通過專業的康復和預防體系降低運動人群的膝關節損傷風險，讓更多患者受益于規范化的醫學教育和科學指導。他對病人福祉的關注與對下一代醫生的培養，一直是推動他不斷前行的動力。正因如此，在我們與他的合作中，不論是疫情困局、國際形勢還是跨國交流的種種實際困難，他始終保持耐心、溫度與責任感。我們一次次被他對醫學與教育的熱愛所打動，也因此更加堅定與他攜手前行的信念。從第一次相識到如今的深度互信，從疫情期間線上共克時艱，到如今線下再次攜手為中國的臨床教育貢獻力量，Petersen教授與我們的合作始終穩固、真誠、互相成就。未來，我們將繼續與Petersen教授一道，讓更多中德醫生彼此學習，讓更多青年醫生找到屬于自己的成長路徑，讓更多患者獲得跨國合作帶來的實實在在的福祉。

 From November 30 to December 5, Prof. Petersen, the Medical Director of the Department of Orthopedics and Trauma Surgery at Martin Luther Hospital Berlin, Former President of the German Knee Society (DKG), and Vice President of German-Austrian-Swiss Society for Orthopaedic-Traumatological Sports Medicine (GOTS) for Germany had a week-long visiting professorship at the Department of Sports Medicine, Guangdong Provincial Hospital of Chinese Medicine in Guangzhou. During his stay, together with Prof. YANG Weiyi, Director of the Department of Sports Medicine, and his team, Prof. Petersen conducted surgical demonstrations and technical discussions on numerous clinical hot topics in knee joint surgery. He engaged in extensive discussions with the team on case management, surgical strategies, and post-operative rehabilitation concepts, sharing real-world clinical insights from Germany with remarkable openness and sincerity. On Friday, Prof. Petersen was invited as an international guest expert to give a keynote lecture at the the "Guangzhou Session of Knee Preservation China Tour", organized by the National Orthopedic Medical Center of China. This visit held far more significance for us than just a week of academic exchange. It represented the continuation and expansion of a collaboration that has been developing over six years, overcoming the challenges of the pandemic and geographical distances. We first came into contact with Prof. Petersen in January 2020, at a time when international exchanges had been forced to pause. But in this difficult period, Prof. Petersen took an unconventional approach and launched the fully virtual International Knee Day, turning the distance blocked by the pandemic into an online bridge. For three consecutive years, Gloryren served as the sole co-organizer in China, setting up live sessions in 12 hospitals across 10 cities in China. This allowed Chinese surgeons to continue to stay connected with the global academic community during the pandemic. Over the three years, 45 Chinese surgeons presented the international stage, with over 570,000 online viewers. This was not only an academic exchange, but also a lasting bond of mutual support. The collaboration over the past six years has never ceased, despite the changing external environment. In clinical education, Prof. Petersen has always remained highly committed to Chinese hospitals and Chinese doctors. He has hosted 7 Chinese visiting fellows in his team, bringing them into the operating room, outpatient clinics, and ward rounds, allowing young Chinese doctors to learn directly in one of Germany's most well-developed clinical systems. Clinically, he teaches skills; personally, he mentors and supports. He invites fellows to gatherings, welcomes them to his home, and helps them adapt to a cultural environments. Both professionally and personally, he makes sure every fellow feels supported, valued, and encouraged. This genuine dedication is also reflected in his sustained support for Chinese doctoral students. In 2025, GE Yizhou from Shanxi Medical University began his doctoral studies in Germany under Prof. Petersen’s supervision. In 2026, he will welcome two new doctoral candidates from Shantou University and Zhangzhou. For each Chinese student, he invests substantial time and resources to create clinical and research conditions that truly foster their professional growth. His passion for nurturing young surgeons extends to his educational efforts in Europe as well. In 2012, he co-founded the German Knee Society with leading experts with a shared vision. Starting with just a dozen members, the society has grown to more than 1,300 knee surgeons. He has organized numerous training courses for young surgeons and launched the STOP-X program, a professional rehabilitation and prevention system designed to reduce knee injuries in athletes and ensure more patients benefit from standardized medical education and scientific guidance. His concern for patient well-being and his dedication to training the next generation of surgeons have always been the driving forces behind his work. Therefore, throughout our collaboration with him, despite the pandemic, international political shifts, and the practical difficulties of Sino-Euro exchanges, he has always maintained patience, warmth, and a sense of responsibility. We have been deeply moved by his passion for medicine and education, which has strengthened our determination to continue working with him. From our first meeting to the deep mutual trust we share now, from overcoming difficulties together during the pandemic to resuming face-to-face collaboration to contribute to clinical education in China, our partnership with Prof. Petersen has always been steadfast, sincere, and mutually enriching. In the future, we will continue to work with Prof. Petersen to enable more Chinese and German surgeons to learn from each other, help more young surgeons find their path of growth, and ensure more patients benefit from the Sino-Euro collaboration.
