OBJECTIVE: To explore the feasibility and effectiveness of suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique for avulsion fractures of the inferior pole of the patella. METHODS: A clinical data of 38 patients with avulsion fractures of the inferior pole of the patella, who met the selective criteria and were admitted between September 2021 and April 2023, was retrospectively analyzed. The fractures were treated with suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique in 18 cases (group A) and steel wire tension-band fixation in 20 cases (group B). There was no significant difference in terms of age, gender, cause of fracture, side of fracture, and disease duration between the two groups ( P>0.05). The length of incision, operation time, occurrence of complications, the range of motion of knee joint, and Böstman score of knee joint at last follow-up were recorded. The fracture healing was evaluated through X-ray films and the time of fracture healing was recorded. RESULTS: All incisions healed by first intention. The length of incision was significantly shorter in group A than in group B ( P<0.05). There was no significant difference in the operation time between the two groups ( P>0.05). All patients were followed up 12-24 months (mean, 16.1 months). X-ray films showed that all fractures healed and there was no significant difference in the healing time between the two groups ( P>0.05). At last follow-up, the range of motion and Böstman score of the knee joint in group A were significantly better than those in group B ( P<0.05). During follow-up, 1 patient (5.6%) in group A had one anchor mild prolapse and 3 patients (15.0%) occured internal fixation irritation in group B. But there was no significant difference in the incidence of complications between the two groups ( P>0.05). CONCLUSION For the avulsion fractures of the inferior pole of the patella, the suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique has advantages of reliable fixation, small incision, avoidance of secondary operation to remove internal fixator, and fewer complications, with definite effectiveness.

OBJECTIVE: To investigate the short-term effectiveness of transtibial pull-out technique combined with side-to-side suture technique in treatment of complete radial tear of lateral meniscus body. METHODS: Between May 2020 and August 2023, 15 patients with complete radial tear of lateral meniscus body were repaired by arthroscopic transtibial pull-out technique combined with side-to-side suture technique. There were 11 males and 4 females, with an average age of 25.2 years (range, 15-43 years). Twelve cases were acute injuries and 3 were chronic injuries. All patients had tenderness in the lateral compartment of the knee. No abnormal alignment was observed on the X-ray films of the knee. MRI showed the complete radial tear of lateral meniscus body without associated injuries such as anterior cruciate ligament or cartilage. Preoperative Lysholm score was 44.5±6.4, International Knee Documentation Committee (IKDC) subjective score was 40.2±8.4, Tegner score was 1.3±1.1, and visual analogue scale (VAS) score for pain was 5.1±1.1. The operation time, incision healing, and complications such as vascular/nerve injury were recorded. During follow-up, the range of motion of the knee and tenderness in the lateral compartment of the knee were observed. The knee function and pain were evaluated using Lysholm score, Tegner score, IKDC subjective score, and VAS score. X-ray films and MRI of the knee were reexamined to assess knee degeneration. RESULTS: The operation time was 60-145 minutes (mean, 89.6 minutes). All incisions healed by first intention, and no complication such as vascular/nerve injury occurred. All patients were followed up 17-56 months (mean, 38.4 months). All patients had no knee extension limitation and 3 cases had tenderness in the lateral compartment of the knee. At last follow-up, the Lysholm score, IKDC subjective score, Tegner score, and VAS score for pain were 85.3±7.8, 82.1±15.7, 4.7±1.2, and 1.5±1.0, respectively, which were superior to those before operation ( P<0.05). Imaging reexamination showed that the meniscus was reset at 1 day after operation, and there was no sign of knee degeneration at last follow-up. CONCLUSION Transtibial pull-out technique combined with side-to-side suture technique can effectively treat the complete radial tear of lateral meniscus body and obtain good short-term effectiveness.

OBJECTIVE: To investigate the effectiveness of arthroscopic double fixation and enhanced suture of long head of biceps tendon (LHBT) in situ for repairing rotator cuff tear. METHODS: A retrospective analysis was conducted on 31 patients with rotator cuff tears and LHBT injuries admitted between June 2022 and November 2023. All patients underwent arthroscopic double fixation and enhanced suture of LHBT in situ. There were 12 males and 19 females, with an average age of 61.6 years (range, 53-76 years). There were 10 cases of acute injury and 21 cases of chronic injury. According to DeOrio and Cofield classification criteria, the degree of rotator cuff tear rated as medium-sized tears in 3 cases, large tears in 12 cases, and massive tears in 16 cases. Associated injuries included 5 cases of shoulder joint adhesions, 12 cases of subscapularis muscle tears, and 31 case of shoulder impingement syndromes. The shoulder range of motion (ROM) (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores [visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, Constant-Murley score] were recorded before operation and at last follow-up. MRI at last follow-up were taken to evaluate the rotator cuff healing and structural integrity. RESULTS: All 31 surgeries were successfully completed with operation time ranging from 90 to 210 minutes (mean, 144 minutes). The 3-5 anchors (mean, 3.8 anchors) were used during operation. All incisions healed by first intention. All patients were followed up 12-29 months (mean, 18.5 months). At 3 months after operation, 2 cases developed joint adhesions, 3 had internal rotation limitations, and 2 experienced residual pain at the intertubercular groove, all resolved with conservative management. No Popeye deformity occurred during follow-up. At last follow-up, shoulder ROM (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores (VAS, UCLA, and Constant-Murley scores) showed significant improvements compared to preoperative values ( P<0.05). At last follow-up, MRI evaluation showed that the rotator cuff healing rate reached 90.3% according to the Sugaya classification criteria. LHBT exhibited normal morphology, course, and continuity without dislocation. Surrounding synovial sheath showed no thickening or effusion. CONCLUSION Arthroscopic double fixation and enhanced suture of LHBT in situ for repairing rotator cuff tear can significantly reduce shoulder joint pain, improve ROM, and achieve a high rotator cuff healing rate.

OBJECTIVE: To summarize the research progress of suture augmentation (SA) in anterior cruciate ligament (ACL) reconstruction. METHODS: A comprehensive review of recent literature about SA in ACL reconstruction at home and abroad was conducted. The efficacy of SA in ACL reconstruction was evaluated by examining the definition, biomechanics, and histological studies of SA, along with its clinical application status in ACL reconstruction. RESULTS: SA demonstrates significant advantages in enhancing the biomechanical stability of ACL grafts, reducing the risk of re-rupture, and accelerating postoperative recovery. Specifically, SA improves graft stiffness, ultimate failure strength, and cyclic stability, thereby diminishing the risk of early postoperative failure and joint instability. Histologically, it fosters remodeling and tendon-bone integration through early load-sharing mechanisms; however, stress shielding may interfere with natural remodeling processes, warranting further attention. Clinically, SA reduces graft failure rates and the need for revision surgeries, markedly improving knee joint stability and functional recovery in young patients. Nevertheless, its impact on graft maturation and potential complications remains controversial. CONCLUSION Despite the many advantages of SA in ACL reconstruction, future endeavors should focus on optimizing tensioning techniques, developing bioactive materials, and conducting large-scale randomized controlled trials to further elucidate its clinical value and scope of applicability, providing a more reliable solution for ACL reconstruction.

OBJECTIVE: To explore the effectiveness of arthroscopic All-inside single needle vertical suture technique in treatment of complete radial tear of the meniscus. METHODS: Between January 2019 and January 2022, 18 patients (18 knees) with complete radial tear of the meniscus were treated by using arthroscopic All-inside single needle vertical suture technique. Among them, there were 12 males and 6 females with an average age of 37.1 years (range, 16-50 years). The causes of radial meniscus tears included the sports injuries in 11 cases, sprains/falls in 4 cases, and traffic accident injuries in 3 cases. The interval between injury and operation was 3-25 days (mean, 11.7 days). All patients had knee joint pain. Knee joint tenderness and McMurray sign were both positive. MRI showed the 15 cases of lateral meniscus tear and 3 cases of medial meniscus tear; 15 cases of anterior cruciate ligament injury, 1 case of posterior cruciate ligament injury, and 15 cases of tibial plateau bone contusion. Six patients underwent isolated meniscus repair and 12 patients with cruciate ligament rupture underwent meniscus repair and simultaneous cruciate ligament reconstruction. The operation time and incidence of postoperative complications were recorded. At last follow-up, the meniscus healing was evaluated according to Barrett's criteria and knee joint MRI, respectively. Lysholm score and International Knee Documentation Committee (IKDC) score were used to evaluate the functional recovery of the knee joint. RESULTS: The operation time was 19-28 minutes (mean, 23.3 minutes) in 6 patients with isolated meniscus repair and 38-52 minutes (mean, 45.8 minutes) in 12 patients with meniscus repair and simultaneous cruciate ligament reconstruction. All incisions healed by first intention. After operation, 1 patient developed the deep vein thrombosis of lower limb, the other patients had no complication. All patients were followed up 12-18 months (mean, 15.2 months). At last follow-up, 16 cases of meniscus reached clinical healing according to Barrett's criteria, with a healing rate of 88.9%. MRI re-examination of the knee joint showed that 5 cases had complete healing of the meniscus, 11 cases had partial healing, and 2 cases did not heal. The total healing rate (complete healing and partial healing) was 88.9%. After operation, the Lysholm score and IKDC score of 18 patients increased compared to preoperative scores, and further improved with time. The differences between different time points were significant ( P<0.05). Six patients with isolated meniscus repair had the same changes in the above scores, and the differences between the different time points were significant ( P<0.05). CONCLUSION The arthroscopic All-inside single needle vertical suture technique can achieve good short-term effectiveness in the treatment of complete radial tears of the meniscus.

OBJECTIVE: To describe a novel arthroscopic technique of modified tri-anchor double-pulley suture-bridge in repairing medium-sized supraspinatus tendon tears and evaluate the early effectiveness. METHODS: Between June 2021 and January 2024, 26 patients with medium-sized supraspinatus tendon tears who underwent arthroscopic modified tri-anchor double-pulley suture-bridge repair and met the selective criteria were included. There were 11 males and 15 females with an average age of 61.4 years (range, 43-74 years). Five patients had a significant history of trauma, while the remaining 21 patients had no apparent cause. The time from symptom onset to hospitalization was 3-25 months (mean, 7.9 months). The effectiveness was evaluated during follow-up, including the scores of University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES), visual analogue scale (VAS), the range of forward flexion, abduction, external rotation, and internal rotation, and patient's satisfaction. Either MRI or ultrasound examination were used to evaluate structural integrity of the tendon. RESULTS: The operation time was 65-110 minutes (mean, 81.8 minutes). All patients were followed up 12-43 months (mean, 23.0 months). At 3 and 12 months after operation, the shoulder range of flexion, abduction, external rotation, and internal rotation, and the scores of VAS, UCLA, and ASES significantly improved when compared with those before operation ( P<0.05). The improvement was further observed at 12 months compared to 3 months ( P<0.05). At last follow-up, 13 patients were very satisfied with the effectiveness, 11 patients were satisfied, 1 was relatively satisfied, and 1 was dissatisfied. During follow-up, 15 patients underwent imaging examination and imaging reexamination showed that the re-tear rate of tendon was 6.6%(1/15). The remaining 11 patients refused imaging examination. Complications included partial anchor withdrawal in 1 case, shoulder stiffness in 5 cases, and mild pain in shoulder joint in 2 cases in physical activity or heavy physical activity. CONCLUSION Arthroscopic modified tri-anchor double-pulley suture-bridge technique is a novel surgical technique that uses double-loaded suture anchors as medial- and lateral-row anchors. In repairing medium-sized supraspinatus tendon tears, 6 sets of double-pulley suture-bridges can be created from one medial-row anchor; knotless medial-row can reduce re-tear rate of the tendon; good early effectiveness is obtained.

OBJECTIVE: To evaluate the early effectiveness of transosseous suture fixation in treating recurrent acute patellar dislocation with patellar osteochondral fractures (OCFs). METHODS: A retrospective analysis was conducted on 19 patients with recurrent acute patellar dislocation and patellar OCFs, who underwent transosseous suture fixation between January 2018 and December 2022 and were followed up 2 years. The cohort included 8 males and 11 females, aged 13-21 years (mean, 16.2 years). Patients experienced 2-5 times of patellar dislocation (mean, 3.2 times). The interval from the last dislocation to operation ranged from 3 to 15 days (mean, 9.6 days). Preoperative imaging revealed the intra-articular osteochondral fragments and medial patellofemoral ligament (MPFL) injury. Clinical outcomes were evaluated using the visual analogue scale (VAS) score for pain, the International Knee Documentation Committee (IKDC) score, the Hospital for Special Surgery (HSS) knee score, the Lysholm score, and the Tegner score. Postoperative complications were recorded. During follow-up, the knee X-ray films, CT, and MRI were taken to evaluate fragment healing, displacement, and the morphology and tension of the MPFL reconstruction graft. RESULTS: All incisions healed primarily, and no complication occurred such as infection, joint stiffness, patellofemoral arthritis, or redislocation. Patients were followed up 24-60 months (mean, 43.5 months). At 12 months postoperatively and the last follow-up, significant improvements ( P<0.05) were observed in VAS, Lysholm, IKDC, HSS, and Tegner scores compared to preoperative values. Further improvements were observed at last follow-up compared with the 12 months postoperatively, and the differences were significant ( P<0.05). Imaging studies demonstrated satisfactory osteochondral fragment positioning with stable fixation. At last follow-up, all fragments had healed, and MPFL reconstruction grafts exhibited optimal morphology and tension. No joint adhesion or fragment displacement occurred. CONCLUSION For recurrent acute patellar dislocation with patellar OCFs, transosseous suture fixation proves to be both safe and effective, achieving satisfactory early effectiveness.

OBJECTIVE: To investigate the effectiveness of the suture anchor technique without knots for reconstruction of the anterior talofibular ligament (ATFL) combined with the reinforcement of the inferior extensor retinaculum in treating chronic lateral ankle instability (CLAI). METHODS: The clinical data of 31 patients with CLAI who were admitted between August 2017 and December 2023 and met the selection criteria were retrospectively analyzed. There were 18 males and 13 females, with an age range from 20 to 48 years (mean, 34.6 years). All patients had a history of repeated ankle sprain, with a disease duration of 6-18 months (mean, 9.65 months). The anterior drawer test and inversion stress test were positive, and tenderness was present in the ligament area. Stress X-ray films of the ankle joint showed a talar tilt angle of (10.00±2.78)° and an anterior talar displacement of (9.48±1.96) mm on the affected side. MRI revealed discontinuity, tortuosity, or disappearance of the ATFL structure. Preoperatively, the visual analogue scale (VAS) score was 5.2±2.1, and the American Orthopaedic Foot and Ankle Society (AOFAS) score was 62.9±7.1. All patients underwent arthroscopic debridement of the ankle joint followed by reconstruction of the ATFL using the suture anchor technique without knots combined with reinforcement of the inferior extensor retinaculum. Postoperatively, pain and function were assessed using the VAS and AOFAS scores. Stress X-ray films were taken to measure the talar tilt angle and anterior talar displacement to evaluate changes in ankle joint stability. Patient satisfaction was assessed according to the Insall criteria. RESULTS: All 31 surgeries were successfully completed. One case had wound exudation, while the remaining surgical incisions healed by first intention. Two cases experienced numbness on the lateral aspect of the foot, which disappeared within 1 month after operation. All patients were followed up 15-84 months (mean, 47.2 months). No complication such as anchor loosening, recurrent lateral ankle instability, superficial peroneal nerve injury, rejection reaction, or wound infection occurred postoperatively. The anterior drawer test and inversion stress test were negative at 3 months after operation. Stress X-ray films taken at 3 months after operation showed the talar tilt angle of (2.86±1.72)° and the anterior talar displacement of (2.97±1.32) mm, both of which were significantly different from the preoperative values ( t=12.218, P<0.001; t=15.367, P<0.001). At last follow-up, 2 patients had ankle swelling after exercise, which resolved spontaneously with rest; all 31 patients returned to their pre-injury level of sports or had no significant discomfort in daily activities. At last follow-up, 25 patients were pain-free, 4 had mild pain after exercise, and 2 had mild pain after walking more than 2 000 meters. The VAS score was 0.8±0.9 and the AOFAS score was 91.6±4.1, both of which were significantly different from the preoperative scores ( t=10.851, P<0.001; t=-19.514, P<0.001). According to the Insall criteria, 24 patients were rated as excellent, 4 as good, and 3 as fair, with a satisfaction rate of 90.3%. CONCLUSION The suture anchor technique without knots for reconstruction of the ATFL combined with reinforcement of the inferior extensor retinaculum provides satisfactory short- and mid-term effectiveness in treating CLAI.

OBJECTIVE: To investigate the surgical method and short-term effectiveness of arthroscopy edge-to-edge #-shaped suture in the treatment of the complete radial tear of the lateral meniscus body. METHODS: The clinical data of 13 patients with complete radial tear of lateral meniscus body between May 2020 and August 2023 were retrospectively analyzed. There were 10 males and 3 females, aged 15-38 years (mean, 24.2 years). There were 11 cases of acute injury and 2 cases of chronic injury, with time from injury to admission ranging from 2 days to 5 months. All patients had tenderness in the lateral joint space, and 2 patients with chronic injury had positive McMurray's sign. All patients were treated with arthroscopic edge-to-edge #-shaped suture technique. The knee joint activity and tenderness in the lateral joint space were detected, and the healing of the incision and the occurrence of complications were observed. X-ray films and MRI of the knee joint were performed to evaluate joint degeneration and meniscus healing. Lysholm score, International Knee Documentation Committee (IKDC) subjective score, Tegner score, and visual analogue scale (VAS) score were used to evaluate the functional recovery before and after operation. RESULTS: The operation time ranged from 46 to 100 minutes (mean, 80.08 minutes). All the incisions healed by first intention, and no complication such as intraoperative vascular and nerve injury or postoperative infection occurred. All 13 patients were followed up 20-59 months (mean, 29.3 months). All patients had no limitation of knee extension and flexion. One patient with chronic injury continued to have tenderness in the lateral space of the knee joint, while the remaining patients had no tenderness, swelling, and locking in the lateral space. Immediate postoperative MRI of knee joint showed continuous recovery of the lateral meniscus. At last follow-up, no degenerative changes were observed in X-ray films of knee joint. Except for 1 patient with chronic injury, the MRI of the other patients showed the healing performance after lateral meniscus suture. Lysholm score, IKDC subjective score, Tegner score, and VAS score all significantly improved when compared with those before operation (P<0.05). CONCLUSION The edge-to-edge #-shaped suture technique can effectively repair the complete radial tear of the lateral meniscus body, and the short-term effectiveness is satisfactory.

OBJECTIVE: To investigate the effectiveness of one-stage direct suture technique under arthroscopy for the treatment of anterior cruciate ligament (ACL) injury combined with anterior meniscus root injury. METHODS: The clinical data of 9 patients with ACL injury or tibial intercondylar eminence fracture combined with anterior meniscus root injury who were admitted between September 2017 and September 2024 and met the selection criteria were retrospectively analyzed. There were 3 males and 6 females, aged 21-62 years, with an average age of 37.1 years. The time from injury to surgery ranged from 5 days to 5 years, with a median time of 40 days. Among them, 5 cases had ACL injury, including 4 cases of type 1 and 1 case of type 2 according to modified Sherman classification; 4 cases had tibial intercondylar eminence fracture, including 3 cases of type 3 and 1 case of type 2 according to Meyers-McKeever classification. There were 7 cases of anterior root injury of lateral meniscus and 2 cases of anterior root injury of medial meniscus. The preoperative International Knee Documentation Committee (IKDC) score was 45.0±12.3, and Lysholm score was 49.2±12.4. Preoperatively, 7 cases were positive in anterior drawer test, Lachman test, and McMurray test, while 2 cases could not complete the test due to pain limitation. Preoperatively and at last follow-up, IKDC score and Lysholm score were used to evaluate knee joint function, anterior drawer test and Lachman test were used to evaluate knee joint stability, and McMurray test was used to evaluate meniscus condition. RESULTS: The operation time was 30-100 minutes, with an average of 64.2 minutes; the total hospital stay was 2-12 days, with an average of 4.5 days; the postoperative hospital stay was 1-4 days, with an average of 1.8 days. All incisions healed by first intention without surgery-related complications. All 9 patients were followed up 2-30 months, with an average of 18.8 months. No internal fixation-related complications occurred during follow-up. At last follow-up, MRI review showed good ligament tension, and CT showed good fracture healing. The results of anterior drawer test and Lachman test were all negative. McMurray test was negative in all cases. The IKDC score was 88.3±5.1, and Lysholm score was 88.3±5.6, both showing significant improvement compared to preoperative scores ( t=14.001, P<0.001; t=10.192, P<0.001). CONCLUSION One-stage direct suture technique under arthroscopy for repairing ACL injury or tibial intercondylar eminence fracture combined with anterior meniscus root injury can achieve good effectiveness without fixation device-related complications.
