Objective: To investigate the feasibility and effectiveness of robot-assisted posterior minimally invasive access in treatment of thoracolumbar tuberculosis via transforaminal expansion approach.

Methods: A clinical data of 40 patients with thoracolumbar tuberculosis admitted between January 2017 and May 2022 and met the selection criteria was retrospectively analyzed. Among them, 15 cases were treated with robot-assisted and minimally invasive access via transforaminal expansion approach for lesion removal, bone graft, and internal fixation (robotic group), and 25 cases were treated with traditional transforaminal posterior approach for lesion removal and intervertebral bone grafting (traditional group). There was no significant difference in the baseline data between the two groups ( P>0.05) in terms of gender, age, lesion segment, and preoperative American Spinal Injury Association (ASIA) grading, Cobb angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP). The outcome indicators were recorded and compared between the two groups, including operation time, intraoperative bleeding volume, hospital stay, postoperative bedtime, complications, ESR and CRP before operation and at 1 week after operation, the level of serum albumin at 3 days after operation, VAS score and ASIA grading of neurological function before operation and at 6 months after operation, the implant fusion, fusion time, Cobb angle of the lesion, and the loss of Cobb angle observed by X-ray films and CT. The differences of ESR, CRP, and VAS score (change values) between pre- and post-operation were calculated and compared.

Results: Compared with the traditional group, the operation time and intraoperative bleeding volume in the robotic group were significantly lower and the serum albumin level at 3 days after operation was significantly higher ( P<0.05); the postoperative bedtime and the length of hospital stay were also shorter, but the difference was not significant ( P>0.05). There were 2 cases of poor incision healing in the traditional group, but no complication occurred in the robotic group, and the difference in the incidence of complication between the two groups was not significant ( P>0.05). There were significant differences in the change values of ESR and CRP between the two groups ( P<0.05). All Patients were followed up, and the follow-up time was 12-18 months (mean, 13.0 months) in the traditional group and 12-16 months (mean, 13.0 months) in the robotic group. Imaging review showed that all bone grafts fused, and the difference in fusion time between the two groups was not significant ( P>0.05). The difference in Cobb angle between the pre- and post-operation in the two groups was significant ( P<0.05); and the Cobb angle loss was significant more in the traditional group than in the robotic group (

Objective: To investigate the benefits and drawbacks of breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer and treatment experience of postoperative operation-related complications.

Methods: A retrospective analysis was performed on clinical data of 26 female patients with breast cancer who met the selection criteria between September 2021 and March 2023 aging 48.7 years (range, 26-69 years). All tumors were unilateral, with 17 on the left side and 9 on the right side. The tumor size ranged from 1.0 to 7.0 cm, with an average of 2.7 cm. The pathological staging included T ₁ in 11 cases, T ₂ in 14 cases, and T ₃ in 1 case; N ₀ in 10 cases, N ₁ in 11 cases, N ₂ in 2 cases, and N ₃ in 3 cases; no distant metastasis (M ₀) occurred when first diagnosed. Among them, 10 cases underwent breast conserving surgery, and 16 cases underwent nipple-sparing mastectomy. All patients underwent breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap. The operation time, incision length, and postoperative drainage volume in 3 days were recorded. Breast-Q "Satisfaction with back" scale was conducted to evaluate patients' satisfaction with back at 6 months after operation.

Results: The operation time was 280-480 minutes (mean, 376.7 minutes), the incision length was 10-15 cm (mean, 12.2 cm), the postoperative drainage volume in 3 days was 500-1 600 mL (mean, 930.2 mL). There were 4 cases of postoperative seroma, 1 case of incision rupture, 1 case of paresthesia of the thoracic wall, and 1 case of edema of the ipsilateral upper limb. All patients were followed up 12-30 months (mean, 20.1 months). No latissimus dorsi muscle flap necrosis, latissimus dorsi muscle atrophy, or shoulder joint dysfunction occurred during follow-up; 2 patients had recurrence of lymph nodes in the ipsilateral axilla after operation, but no distant metastasis occurred. Breast-Q score at 6 months after operation was 64-100 (mean, 79.5). The average score was 78.6 (range, 64-100) in patients underwent nipple-sparing mastectomy and 81.0 (range, 78-100) in patients underwent breast conserving surgery.

Conclusion: Breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer is proven to be a surgical approach with safety and cosmetic effects with mild postoperative operation-related complications and considerable patient satisfaction.

Objective: To compare the mid-term effectiveness of arthroscopic shoulder capsular release combined with acromiohumeral distance (AHD) restoration in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder.

Methods: A retrospective analysis was conducted on clinical data of 22 patients with diabetic secondary stiff shoulder (group A) and 33 patients with primary frozen shoulder (group B), who underwent arthroscopic 270° capsular release combined with AHD restoration treatment. There was no significant difference between the two groups in gender, age, affected side, disease duration, and preoperative AHD, shoulder flexion range of motion, abduction range of motion, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS) score, and Constant score ( P>0.05). Only the difference in the internal rotation cone rank and external rotation range of motion between the two groups showed significant differences ( P<0.05). The improvement in shoulder pain and function was evaluated by using VAS score, ASES score, and Constant score before operation and at last follow-up. Active flexion, abduction, external rotation range of motion, and internal rotation cone rank were recorded and compared. AHD was measured on X-ray films.

Results: All patients were followed up 24-92 months (median, 57 months). There was no significant difference in follow-up time between group A and group B ( P>0.05). No fractures or glenoid labrum tears occurred during operation, all incisions healed by first intention, and no complication such as wound infection or nerve injury was observed during the follow-up. At last follow-up, there were significant improvements in active flexion, abduction, external rotation range of motion, internal rotation cone rank, AHD, VAS score, ASES score, and Constant score when compared with preoperative ones in both groups ( P<0.05). Except for the difference in change in external rotation range of motion, which had significant difference between the two groups ( P<0.05), there was no significant difference in other indicators between the two groups ( P>0.05).

Conclusion: Arthroscopic capsular release combined with AHD restoration can achieve good mid-term effectiveness in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder. However, the improvement in external rotation range of motion is more significant in the patients with diabetic secondary stiff shoulder.

Objective: To analyze the kinematic changes of the hip joint after total hip arthroplasty (THA) through three-dimensional gait analysis.

Methods: Patients with hip joint diseases admitted between October 2022 and June 2023 were selected as the subjects. The patients who met the selective criteria were finally included in the THA group. The healthy volunteers matched with the THA group in the same age were included as the control group. Baseline data including age, gender, body mass index (BMI), and laterality were compared between the two groups. The Harris hip score (HHS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were recorded preoperatively and at last follow-up in the THA group. Three-dimensional motion capture system was utilized to collect spatiotemporal parameters and kinematic data during walking, including stride length, cadence, and maximum/minimum values, range of motion (ROM) in hip joint abduction/adduction, external/internal rotation, and flexion/extension, as well as gait scores. Differences between the two groups were analyzed. Additionally, the correlation between gait scores and postoperative HHS and WOMAC scores were analyzed in the THA group. Finally, the kinematic data of each degree of freedom (DOF) were fitted into a gait diagram, and the dynamic changes of the 3-DOF of the hip joint during the gait cycle were quantitatively analyzed.

Results: There was no significant difference in gender, age, laterality, and BMI between the two groups ( n=20, P>0.05). The mean follow-up time in the THA group was 9.9 months (range, 6-12 months). The HHS and WOMAC scores at last follow-up in the THA group showed significant improvement when compared with preoperative scores ( P<0.05). Gait scores were positively correlated with postoperative HHS score ( r=0.585, P=0.007) and negatively correlated with WOMAC score ( r=-0.619, P=0.004). There was no significant difference in stride length and cadence between the THA and control groups ( P>0.05), but gait score was significantly lower in the THA group than in the control group ( P<0.05). There was no significant difference in maximum and minimum values of flexion/extension, external/internal rotation, and abduction/adduction between the two groups ( P>0.05); however, ROM in the THA group was significantly lower than that in the control group ( P<0.05). There were significant differences between the two groups of flexion/extension in multiple phases of the gait cycle ( P<0.05).

Conclusion: Early post-THA hip joint kinematics exhibit relative adduction, external rotation, and flexion during the gait cycle compared to normal individuals, with incomplete recovery of kinematic parameters in three degrees of freedom. Significant differences in flexion are observed at multiple phases of th

Objective: To investigate the effectiveness of endoscopic radical mastectomy for breast cancer combined with total pectoral muscle reconstruction with breast implants.

Methods: The clinical data of 138 female patients with breast cancer who met the selection criteria between April 2019 and December 2023 were retrospectively analyzed. The mean age of the patients was 43.8 years (range, 27-61 years). The maximum diameter of the tumors ranged from 1.00 to 7.10 cm, with an average of 2.70 cm. Pathological examination showed that 108 cases were positive for both estrogen receptor and progesterone receptor, and 40 cases were positive for human epidermal growth factor receptor 2. All patients underwent endoscopic radical mastectomy for breast cancer combined with total pectoral muscle reconstruction with breast implants. The operation time, intraoperative blood loss, prosthesis size, and occurences of nipple-areola complex (NAC) ischemia, flap ischemia, infection, and capsular contracture were recorded. The Breast-Q2.0 score was used to evaluate breast aesthetics, patient satisfaction, and quality of life (including the social mental health score, breast satisfaction score, and chest pain score). Patients were divided into two groups based on the time of operation after the technique was implemented: group A (within 1 year, 25 cases) and group B (after 1 year, 113 cases). The above outcome indicators were compared between the two groups. Furthermore, based on the postoperative follow-up duration, patients were classified into a short-term group (follow-up time was less than 1 year) and a long-term group (follow-up time was more than 1 year). The baseline data and postoperative Breast-Q2.0 scores were compared between the two groups.

Results: The average operation time was 120.76 minutes, the average intraoperative blood loss was 23.77 mL, and the average prosthesis size was 218.37 mL. Postoperative NAC ischemia occurred in 21 cases (15.22%), flap ischemia in 30 cases (21.74%), infection in 23 cases (16.67%), capsular contracture in 33 cases (23.91%), and prosthesis removal in 2 cases (1.45%). The operation time of group A was significantly longer than that of group B ( P<0.05), and there was no significant difference in intraoperative blood loss, prosthesis size, and related complications between the two groups ( P>0.05). All patients were followed up 3-48 months (mean, 20 months). There were 33 cases in the short-term group and 105 cases in the long-term group. There was no significant difference in baseline data such as age, body mass index, number of menopause cases, number of neoadjuvant chemotherapy cases, number of axillary lymph node dissection cases, breast cup size, degree of breast ptosis, and postoperative radiotherapy constituent ratio between the two groups ( P>0.05). At last follow-up, the breast satisfaction score in the patients' Breast-Q2.0 score rang

Objective: To investigate whether different degrees of primary varus knee affect joint function and stability in patients undergoing anterior cruciate ligament (ACL) reconstruction.

Methods: A clinical data of 160 patients with primary varus knee, who were admitted between January 2020 and December 2021 and met the selection criteria, was retrospectively analyzed. All patients underwent primary ACL reconstruction using autologous single-bundle hamstring tendon. Patients were divided into three groups based on the hip-knee-ankle angle (HKA): group A (64 patients with HKA 0°-3°), group B (55 patients with HKA 3°-6°), and group C (41 patients with HKA 6°-9°). Except for the significant difference in HKA among the three groups ( P<0.05), baseline data such as age, gender, affected side, body mass index, interval between injury and operation, Kellgren-Lawrence grading, posterior tibial slope, proportion of combined meniscal injuries, Tegner score, Lysholm score, and International Knee Documentation Committee (IKDC) objective score, anterior drawer test, Lachman test, pivot shift test, and the results of KT1000 (side-to-side difference, SSD) showed no significant difference ( P>0.05). At last follow-up, joint stability was assessed through the anterior drawer test, Lachman test, pivot shift test, and SSD; joint function was evaluated using the Tegner score, Lysholm score, and IKDC objective score.

Results: All incisions in the three groups healed by first intention after operation. All patients were followed up 24-31 months, with an average of 26 months; there was no significant difference in the follow-up time among the three groups ( Z=0.675, P=0.714). At last follow-up, the knee stability and functional assessment indicators in each group significantly improved when compared to preoperative ones ( P<0.05); there was no significant difference among the three groups ( P>0.05) in terms of the anterior drawer test, Lachman test, pivot shift test, IKDC objective scores, and the changes of the Lysholm scores and Tegner scores. The Kellgren-Lawrence grading and HKA at last follow-up were consistent with preoperative results in the three groups.

Conclusion: Varying degrees of primary varus knee do not affect early knee joint stability and functional recovery after ACL reconstruction, and there is no significant difference in effectiveness between different degrees of varus knee.

Objective: To review the development of endoscopic techniques in breast surgery, focusing on their use in benign breast lump resection and breast-conserving surgery for cancer, and also summarize the development and application of these techniques in China, highlighting promotion and homogenization challenges and future directions.

Methods: A systematic review of relevant literature was conducted to trace the historical evolution, clinical applications, and related research of endoscopic techniques in breast surgery, emphasizing their advantages and disadvantages of endoscopic benign breast lump resection and breast-conserving surgery for cancer.

Results: Endoscopic benign breast lump resection and breast-conserving surgery for cancer have improved patients' postoperative psychological health and quality of life, particularly in scar-free surgery. However, challenges such as limited intraoperative visibility and prolonged surgery time lead to controversy in clinical practice.

Conclusion: Despite significant advancements, endoscopic techniques in breast surgery also face challenges. Future efforts should focus on technological improvements and clinical research to address these issues, promoting widespread application and standardization. The key to future development lies in the promotion and homogenization of these technologies.

Objective: To explore the surgical technique and preliminary safety and aesthetic results of endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation for patients.

Methods: The clinical data of 25 patients who underwent endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation between April 2020 and January 2024 and met the selection criteria was retrospective analysed. The patients' age ranged from 33 to 73 years, with a mean of 50.4 years, and the body mass index ranged from 16.8 to 26.6 kg/m ², with a mean of 21.5 kg/m ². They were all bilaterally injected with Amazingel, and the time between initial injections and surgery ranged from 17 to 26 years, with a mean of 21.4 years. Early safety was evaluated by the incidence of early postoperative complications, and early aesthetic results were evaluated using Harris scores (including breast shape satisfaction, sensation satisfaction, and elasticity satisfaction) at 3 months after operation.

Results: There were 9 cases underwent Amazingel removal (group A) and 16 cases underwent Amazingel removal with immediate prepectoral implant-based breast augmentation (group B). Intraoperative removal of Amazingel ranged from 808 to 1 285 mL, with a mean of 1 050.7 mL; the mass of the capsule removed ranged from 36 to 169 g, with a mean of 103.6 g; and a gross anatomical prosthesis was used with a median size of 345 mL (range, 315-355 mL). The operation time ranged from 95 to 395 minutes, with a mean of 194.2 minutes; and the cost of the procedure ranged from 8000to 91 000 yuan, with a mean of 33 000 yuan. Patients had a median follow-up time of 22.7 months (range, 3.0-48.1 months). There was 1 case of intraoperative skin burn due to the operation of the electric scalpel, which healed naturally after operation without flap necrosis. There was no adverse conditions such as prosthesis outline showing, ripple sign, and capsular contracture during follow-up; a small amount of Amazingel residue was found in 2 patients at 1 year after operation. The Harris score at 3 months after operation was used to evaluate the early aesthetic results, and the breast shape, elasticity, and sensation satisfaction of group A were lower than group B, but the differences between the two groups were not significant ( P>0.05).

Conclusion: Endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation is safe in the early stage with good aesthetic results, and it is also recommended that patients who had the indications for combined immediate breast augmentation after removal to rebuild the breast appearance.

Objective: To review the research progress related to endoscopic surgery and robotic surgery for breast diseases, aiming to provide references for clinical practice.

Methods: The recent domestic and international literature on endoscopic surgery and robotic surgery for breast diseases was reviewed, then the challenges in their development, the innovative evolution of endoscopic surgery combined with clinical practice by our team, and its clinical applications were summarized.

Results: Traditional endoscopic surgery, despite its advantages such as minimal invasiveness, good cosmetic outcomes, and high patient's satisfaction, has been limited in its development due to specific difficulties in establishing the operative field. Our team innovatively proposed the "reverse sequence method" and the Huaxi Hole 1 theory and methods, cleverly altering the surgical procedure sequence, adding small operative orifices to transform single-port operations into multi-port ones, effectively overcoming the challenges restricting the advancement of endoscopic surgery in the field of breast diseases, thereby enabling further proliferation of endoscopic procedures. In terms of breast endoscopic reconstruction surgery, the parachute patch technique has broadened the indications for reconstruction surgery, benefiting patients with a certain degree of breast ptosis; and the postoperative adjustment concept, through early intervention in the post-reconstruction breast shape, has further refined the reconstruction procedure. Robot-assisted surgery derived from endoscopic surgery theory has further enhanced the precision and stability of surgeries, reducing surgical risks; however, excessive time and economic costs are urgent issues that must be addressed.

Conclusion: Through theoretical innovations, endoscopic surgery has been applied in the excision and reconstruction of breast lesions, while robotic surgery shows promising applications in autologous breast reconstruction, especially in the latissimus dorsi reconstruction field. Nevertheless, the lack of high-level large-sample, multi-center randomized controlled clinical trials to confirm its surgical safety, oncological safety, and postoperative cosmetic outcomes is an important direction for future research.

Objective: To investigate the effectiveness of the reverse traction device in the preoperative treatment of high-energy tibial plateau fractures.

Methods: A retrospective study was conducted to analyze the clinical data of 33 patients with high-energy tibial plateau fractures who met the selection criteria between December 2020 and December 2023. All patients were treated by open reduction and internal fixation. According to the preoperative traction method, they were divided into the observation group (16 cases, treated with a reverse traction device on the day of admission) and the control group (17 cases, treated with heel traction on the day of admission). There was no significant difference in baseline data such as gender, age, body mass index, affected side, cause of injury, fracture Schatzker classification between the two groups ( P>0.05). Preoperative waiting time, preoperative related complications (nail channel loosening, nail channel oozing, nail channel infection, soft tissue necrosis, soft tissue infection, deep vein thrombosis of the lower extremity, etc.), operation time, and total hospitalization time were recorded and compared between the two groups. On the 4th day after traction, visual analogue scale (VAS) score was used to evaluate the pain relief of the patients, the swelling value of the affected limb was measured, and the Immobilization Comfort Questionnaire (ICQ) score was used to evaluate the perioperative hospital comfort of the patients.

Results: Both groups of patients completed the operation successfully, and the operation time, total hospitalization time, and preoperative waiting time of the observation group were significantly less than those of the control group ( P<0.05). There was no preoperative related complications in the observation group; in the control group, 3 patients had nail channel loosening and oozing, and 2 cases had the deep vein thrombosis of the lower extremity; the difference in the incidence of complication between the two groups was significant ( P<0.05). On the 4th day after traction, the ICQ score, VAS score, and limb swelling value of the observation group were significantly better than those of the control group ( P<0.05). X-ray films showed that the tibial plateau fracture separation and lower limb alignment recovered after calcaneal traction in the control group, but not as obvious as in the observation group. The fracture gap in the observation group significantly reduced, the tibial plateau alignment was good, and the lateral angulation deformity was corrected.

Conclusion: The use of reverse traction treatment in patients with high-energy tibial plateau fractures on admission can accelerate the swelling around the soft tissues to subside, reduce patients' pain, shorten the preoperative waiting time, improve the patients' preoperative quality of life, and contribut
