Ceremony for the Establishment of the Sino-German Communication Center for Sports Medicine

On the morning of Nov. 11, guided by the team from the Sports Med Department of the Shenzhen Second People's Hospital, Prof. Grim visited the Sports Med Department and the ORs of the hospital, paving the way for the facilitation of this academic exchange.

Subsequently, Chief Physicians of the Department, Director OUYANG and Director PENG Liangquan, presented surgical cases and surgical plans of the day with Prof. Grim. Prof. Grim then provided surgical guidance on the arthroscopic reconstruction of the PCL of the knee as well as arthroscopic repair of recurrent dislocations of the shoulder (Bankart's injury).

In the afternoon, Prof. LU Wei, Director of the Department of Sports Medicine of Shenzhen Second People's Hospital, held a welcome ceremony for Prof Grim. Both sides celebrated the establishment of the Sino-German Communication Center for Sports Medicine in Shenzhen Second People's Hospital, which will become an important platform for exchange between both sides on Sports Medicine.

Prof. Grim introduced the Osnabrück Hospital and kicked off the week with a lecture entitled Comparison of treatment options for shoulder instability after sports injuries, in which he explained the incidence of shoulder instability after sports injuries, the different types of injuries, diagnostic strategies, management of bone defects, typical surgical procedures, and instability scores, to give a comprehensive overview of the management of these cases.

Surgical Instructions

On the morning of November 12th, Prof. Grim arrived at the Department of Sports Medicine, Shenzhen Second People’s Hospital, where he discussed the basic condition of newly admitted patients with the core members of the surgical team. He reviewed the patients’ medical history and imaging data, and participated in discussions regarding the treatment plans.

Subsequently, Prof. Grim, accompanied by Director LU Wei’s team, participated in surgical guidance. Prof. Grim instructed several surgeries performed by the team, including ACL and PCL reconstruction, Bankart lesion repair with rotator cuff repair, and repair of recurrent shoulder dislocations. During the surgeries, Prof. Grim provided on-site commentary and recommendations on specific surgical techniques.

In his instruction on the key techniques for Bankart lesion repair, Prof. Grim emphasized the importance of the anchor fixation entrance points and angles. The control of these entrance points and angles is typically monitored by C-arm intraoperatively. However, Prof. Grim’s research team is also exploring using ultrasound imaging for precise localization of the entrance points and angles of the anchor. Ultrasound imaging is a widely used medical device in clinical practice, and if it can be introduced into the OR for precise pinpointing of the entrance points during Bankart lesion repair, it would be an intraoperative imaging control that's well worth promoting. Regarding arthroscopic ACL and PCL reconstruction, Prof. Grim shared that he tends to preserve the remnant of ACL when possible, but for PCL reconstruction, he prefers removing remnant rather than remnant preservation.

Lectures on Sports Med topics to Share Advanced Treatment Concepts

On the morning of November 13th, Prof. Grim, along with Diector LU Wei’s team, first held a discussion on challenging cases, reviewing the recovery of surgical cases from the previous day, as well as the basic conditions and surgical plans for the patients scheduled for surgery that day.

Subsequently, Prof. Grim participated in the day's surgeries and provided surgical guidance. He observed surgeries performed by the team of Dr. OUYANG Kan, the Deputy Director of the department, including hip arthroscopy and supraspinatus tendon tear repair, offering intraoperative instructions and suggestions for some surgical techniques.

On the afternoon of November 13th, Prof. Grim conducted a specialized lecture and case report session with the key team members of the Sports Medicine Department at Shenzhen Second People's Hospital. Prof. Grim kicked off the afternoon's activities with a lecture titled Advanced Treatment Concepts for Acromioclavicular Joint Instability, offering new perspectives for the standardized treatment of AC joint instability.

And then, Dr. LIU Yuwei from the department presented the team’s experience in treating hip impingement, shared the current status of hip arthroscopy techniques in the department, and engaged in case discussions with Prof. Grim.

Prof. Grim also participated in a research discussion with Director LU Wei's research team and the sports medicine research team led by Prof. AO from Peking University Third Hospital. The group jointly discussed basic experimental projects related to the modified arthroscopic Latarjet technique, offering strategic input and ideas. The exchange of perspectives between Chinese and European researchers provided new insights for the department’s scientific research.

Surgical Guidance

During the surgical guidance session on the morning of November 14th, Prof. Grim observed an acromioplasty and shared that, in their hospital, they usually place the camera in the posterior portal and accessing the injuried parts through anterior-lateral portal for the acromion in arthroscopy. During the subsequent guidance on rotator cuff repair, Prof. Grim also provided postoperative rehabilitation recommendations, noting that rotator cuff injury rehabilitation requires six-week wearing of sling with passive exercises, and active training can only begin six weeks later.

In the afternoon, Prof. Grim, accompanied by Dr. ZHU Weimin, the department's Chief Physician of the Sports Med. Department and Director of the hospital's Quality Control Department, provided surgical guidance on the treatment of recurrent patellar dislocation and knee cartilage defects, including the use of artificial tissue engineering cartilage for cartilage defect on the knee joint.

Prof. Grim and Director ZHU engaged in an in-depth discussion on the topics of clinical research projects. Director ZHU shared details about the clinical research he is leading, including studies on knee cartilage therapy, ACL and PCL reconstruction, and particularly the follow-up research on cartilage repair therapies. Director ZHU outlined the current progress of these projects and expressed his expectations for future clinical applications. He hoped that with Prof. Grim's visit to the hospital, ongoing and in-depth scientific exchange and collaboration could also be kicked off.

A Successful Closure

On the morning of November 15th, Prof. Grim, together with the department members, conducted an expert lecture session. During the session, Prof. Grim delivered two lectures: Prevention of Shoulder Injuries and Management of the Long Head of the Biceps Tendon. Whether driven by the need to promote national fitness campaign or to reduce healthcare costs and resources, the prevention of shoulder injuries is crucial, requiring wider promotion and public education. Therefore, Prof. Grim’s lecture on shoulder injury prevention is particularly significant in the context of China's growing national fitness trend.

In the afternoon, Prof. Grim conducted surgical guidance on ankle ligament reconstruction and fracture reduction. Prof. Grim first reviewed the case presentations from the department’s doctors regarding patients with ankle ligament injuries and fractures. He then engaged in discussions with the surgical team on the approach of the surgeries, reduction techniques, and the management of bone loss.

Prof. Grim’s week-long visiting professorship at the Sports Medicine Department of Shenzhen Second People's Hospital came to a perfect closure. Prof. Grim and the department team summarized the week’s academic exchange activities and discussed future prospects for continued collaboration in both clinical practice and research. As an emerging sub-specialty, Sports Medicine holds significant strategic importance for the development of healthcare. This academic exchange has been a key opportunity for Sino-German cooperation in the field of Sports Medicine. Over the past week, both sides have gained a deeper understanding of each other's research directions and treatment strengths, and we expect further and comprehensive collaboration to promote the progress and development on Sports Medicine for the hospital
