OBJECTIVE: To investigate the effectiveness of three-dimentional (3D) printed personalized guide plate-assisted wrist arthroscopic repair for Palmer type ⅠB triangular fibrocartilage complex (TFCC) injury. METHODS: A retrospective analysis was conducted on the clinical data of 20 patients with Palmer type ⅠB TFCC injuries admitted between January 2023 and March 2024 who met the selection criteria. Among them, 13 were male and 7 were female; ages ranged from 23 to 35 years, with a mean age of 30.3 years. All patients had a history of trauma, 12 cases involved falls and 8 cases involved sprains. All patients demonstrated a positive "piano key sign". MRI revealed deep ulnar-side tears of the TFCC. Conservative treatment for 6 weeks yielded poor or no clinical improvement. The interval from injury to surgery ranged from 2 to 9 months, with a mean of 5.0 months. Patients underwent wrist arthroscopic repair assisted by 3D printed personalized guide plate. Functional recovery was assessed preoperatively and postoperatively using the visual analogue scale (VAS) score for pain, modified Mayo wrist score, and range of motion (ROM) measurements for wrist flexion-extension, ulnar-radial deviation, and pronation-supination. At last follow-up, MRI was performed to evaluate the healing of TFCC. RESULTS: All 20 patients underwent successful surgery without complications such as vascular or nerve injury, fracture, incisional infection, or joint stiffness. All patients were followed up 9-18 months (mean, 12.4 months). At last follow-up, patients demonstrated significant improvements in VAS scores, modified Mayo wrist scores, wrist flexion-extension ROM, ulnar-radial deviation ROM, and pronation-supination ROM compared to preoperative levels ( P<0.05). MRI at last follow-up showed preserved TFCC continuity, excellent healing, and secure fixation. CONCLUSION 3D-printed personalized guide plate significantly improve outcomes in wrist arthroscopic TFCC repair for Palmer type ⅠB injuries. They enable high-quality suturing, facilitate anatomical reconstruction, and markedly enhance wrist function.

Objective To evaluate the clinical outcomes of 514 cases of anterior cruciate ligament(ACL)reconstruction using hamstring tendon autograft and to observe postoperative changes and recovery of the grafts through second-look arthroscopy.Methods This retrospective study collected data from 514 patients who underwent ACL reconstruction with hamstring tendon autograft between May 2015 and June 2018,with a follow-up of at least one year.Knee function recovery and stability were assessed using the Lysholm score,International Knee Documentation Committee(IKDC)score,and Tegner score,along with the pivot shift test and Lachman test.During the second-look arthroscopy,key observations included the synovial coverage,continuity of the reconstructed ligament,and any intra-articular abnormalities.Results The time interval between ACL reconstruction and second-look arthroscopy ranged from 12 to 28 months,with an average of 20 months.Postoperative infection occurred in 2 cases,both of which were successfully treated with arthroscopic debridement and drainage.No other patients experienced infections,graft resorption,or other complications.At the second-look arthroscopy,the Lysholm score significantly improved from(43.56±9.89)preoperative to(92.21±6.12)postoperatively,the difference was statistically significant(P<0.05);The IKDC score increased from(20.32±7.87)to(85.67±10.43),the difference was statistically significant(P<0.05);The Tegner score improved from(4.31±0.82)to(6.61±1.21),the difference was statistically significant(P<0.05).Second-look arthroscopy revealed that the ligament remained intact in 375 patients,with partial tears in 139 patients,ligament tension was maintained in 447 patients,while 67 patients had laxity,the reconstructed ACL graft was deemed to be in good condition in 435 patients and suboptimal in 79 patients,there were significant differences observed in pre-and post-pivot shift test and Lachman test(P<0.05);Among the 514 patients,188(36.58%)successfully returned to sport.Conclusion ACL reconstruction using hamstring tendon autograft effectively restores knee function and stability.In patients followed for more than one years,the grafts show good vascularization and synovial coverage.Emphasis should be placed on systematic postoperative rehabilitation to optimize recovery.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

BACKGROUND:Impaired hamstring muscle strength,anterior patellar pain,high incidence of osteoarthritis,and loss of proprioception after anterior cruciate ligament reconstruction lead to poor functional recovery due to a higher incidence of osteoarthritis and loss of proprioception.Arthroscopic repair of the anterior cruciate ligament combined with dynamic or static internal brace repair preserves the original ligament structure and results in favorable short-term outcomes. OBJECTIVE:To prospectively observe the efficacy and imaging findings of modified double-bundle arthroscopic repair of the anterior cruciate ligament after Sherman type Ⅰ injury METHODS:From January 2020 to September 2022,a total of 60 patients with anterior cruciate ligament injury admitted at the Department of Sports Medicine,Foshan Hospital of Traditional Chinese Medicine were included and divided into two groups(n=30 per group)according to the treatment protocols.The functional repair group was treated with double bundle repair combined with internal brace fixation,and the reconstruction group was treated with single bundle anatomical reconstruction of autologous hamstring muscle.All cases were followed up for 12 months after surgery,and International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the affected and healthy sides of the two groups were evaluated at 3,6 and 12 months after surgery. RESULTS AND CONCLUSION:Three months after surgery,International Knee Documentation Committee scores,Lysholm scores and KT-1000 difference between the affected and healthy sides were significantly different between the two groups(P＜0.05),and the functional repair group was better than the reconstruction group.At 6 and 12 months after surgery,there was no significant difference in International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the two groups(P＞0.05).To conclude,anterior cruciate ligament repair preserves the original ligament structure,avoids drilling larger marrow tracts and removing autologous tendons for reconstruction,reduces the damage to the original normal structure,and has fewer complications.Early postoperative efficacy is better than that of anterior cruciate ligament reconstruction with stumps,but there is no significant difference in the efficacy of the two groups 6 months after surgery.

For the detection of steatosis, quantitative ultrasound imaging techniques have achieved great progress in past years. Magnetic resonance imaging proton density fat fraction is currently the most accurate test to detect hepatic steatosis. Some blood biomarkers correlate with non-alcoholic steatohepatitis, but the accuracy is modest. Regarding liver fibrosis, liver stiffness measurement by transient elastography (TE) has high accuracy and is widely used across the world. Magnetic resonance elastography is marginally better than TE but is limited by its cost and availability. Several blood biomarkers of fibrosis have been used in clinical trials and hold promise for selecting patients for treatment and monitoring treatment response. This article reviews new developments in the non-invasive assessment of non-alcoholic fatty liver disease (NAFLD). Accumulating evidence suggests that various non-invasive tests can be used to diagnose NAFLD, assess its severity, and predict the prognosis. Further studies are needed to determine the role of the tests as monitoring tools. We cannot overemphasize the importance of context in selecting appropriate tests.
