Objective
To investigate the methods and effectiveness of surgical treatment for posteromedial corner (PMC) injury combined with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) ruptures.
Methods
Between February 2009 and February 2012, 15 patients (15 knees) with PMC injury combined with ACL and PCL ruptures underwent PMC repair with suture anchor and ACL and PCL reconstruction. There were 7 males and 8 females with an average age of 39 years (range, 15-59 years). The causes of injury were traffic accident injury in 6 cases, sport injury in 7 cases, and sprain injury in 2 cases. The disease duration was 3-15 days with an average of 7 days. All patients presented positive results of anterior drawer test, posterior drawer test and valgus stress test, and dysfunction of knee joint. Of 15 cases, 3 had ACL and PCL ruptures, 5 had ACL rupture, 3 had ACL injury at the attachment point of the condyles crest, and 4 had PCL rupture; 9 had PMC tear at the femur insertion, 5 had PMC tear at the tibia insertion, and 1 had PMC tear in the body area.
Results
All incisions healed by first intention with no complication of infection or stiffness of knee. All cases were followed up 18.4 months on average (range, 10-36 months). At last follow-up, 14 cases had normal knee flexion and extension ranges, but 1 case had 10° limitation of the knee extension. Except 1 case which had weakly positive valgus stress test, the other patients showed negative results of anterior drawer test, posterior drawer test, and valgus stress test. Based on the improved Lysholm classification standard, the results were excellent in 8 cases, good in 5 cases, and fair in 2 cases; the excellent and good rate was 86.7%.
Conclusion
Early repair of the PMC and reasonable reconstruction of cruciate ligament can effectively restore the knee stability for patients with PMC injury combined with ACL and PCL ruptures.
Magnetic anchoring and traction technique is one of the core technologies of magnetic surgery. With the "non-contact" traction force of the outer magnet on the inner magnet, we can drive the inner magnet and the gripper to multiple directions, and pull tissue or organ to required position in operations, so as to get a clearer surgical field of view. On the basis of the previous animal experiments, we applied magnetic anchoring and traction device in 3 human (males aged 63-71 years) thoracoscopic esophagectomies. Using the magnetic anchoring device, we could pull the esophagus dorsally or ventrally to assist in exposing the anatomical plane without special equipment or pleural puncture for retraction of the esophagus. The interference between operating instruments reduced. The mean blood loss in operation was 83 mL, the mean total operation time was 253 min and the mean length of hospital stay was 10 d. Postoperative follow-up showed that all 3 patients had good short-term prognosis. There was no swellling or pain in magnetic anchoring zone of chest wall.
Objective To investigate effectiveness of suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling in the treatment of patellar inferior pole fractures. Methods A clinical data of 37 patients with unilateral patellar inferior pole fracture who met the selection criteria between June 2017 and June 2021 was retrospectively analyzed. Among them, 17 cases were treated with the suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling (group A), and 20 cases were treated with the traditional Kirschner wire tension band technique (group B). There was no significant difference in terms of gender, age, body mass index, fracture side, combined medical disease, and preoperative hemoglobin between the two groups (P>0.05). Operation time, intraoperative blood loss, postoperative complications, fracture healing time, knee range of motion, and knee function Bostman score (range of motion, pain, daily work, muscle atrophy, walking aids, knee effusion, soft leg, and stair climbing) and grading were recorded in both groups at last follow-up. Results There was no significant difference in operation time and intraoperative blood loss between the two groups (P>0.05). All incisions healed by first intention. All patients were followed up 1-2 years, with an average of 1.7 years. X-ray films reexamination showed that all fractures in group A healed, while 2 cases in group B did not heal. There was no significant difference in bone healing time between the two groups (P>0.05). At last follow-up, the knee range of motion, the range of motion score of Bostman score, total score and effectiveness grading in group A were significantly better than those in group B (P<0.05). There was no significant difference in the other items of Bostman scores between the two groups (P>0.05). During follow-up, 2 cases of internal fixation failure and 1 case of internal fixator irritation occurred in group B, and no complication related to internal fixation occurred in group A. The occurrence of complications was significantly lower in group A than in group B (P<0.05). ConclusionCompared with the traditional Kirschner wire tension band technique, the suture anchor combined with Nice knot strapping via longitudinal patellar drilling for the patellar inferior pole fractures has the advantages of simple operation, reliable fixation, early flexion and extension activity, and better functional recovery of knee joint.
ObjectiveTo compare the effectiveness and safety of preoperative lung localization by microcoil and anchor with scaled suture.MethodsA total of 286 patients underwent CT-guided puncture localization consecutively between October 2019 and December 2020 in our hospital. According to the different methods of localization, they were divided into a microcoil group (n=139, including 49 males and 90 females, aged 57.92±10.51 years) and an anchor group (n=147, including 53 males and 94 females, aged 56.68±11.31 years). The clinical data of the patients were compared.ResultsA total of 173 nodules were localized in the microcoil group, and 169 nodules in the anchor group. The localization success rate was similar in the two groups. However, the anchor group was significantly better than the microcoil group in the localization time (8.15±2.55 min vs. 9.53±3.08 min, P=0.001), the pathological receiving time (30.46±14.41 min vs. 34.96±19.75 min, P=0.029), and the hemoptysis rate (10.7% vs. 30.1%, P=0.001), but the pneumothorax rate was higher in the anchor group (21.3% vs. 11.0%, P=0.006).ConclusionPreoperative localization of small pulmonary nodules using anchor with suture is practical and safe. Due to its simplicity and convenience, it is worth of promotion in the clinic.
Objective To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures. Methods The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up. Results All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5). ConclusionKirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.
Objective To investigate the effectiveness of disc reduction and anchorage in treatment of diacapitular condylar fracture with disc displacement. Methods Between June 2019 and June 2021, 20 patients (27 sides) with diacapitular condylar fractures with disc displacement were treated with disc reduction and anchorage combined with internal fixation. There were 15 males and 5 females with a median age of 40 years (range, 8-65 years). The fractures were caused by falling from height in 3 cases, traffic accident in 3 cases, and falling in 14 cases. Among them, there were 13 cases of unilateral fracture and 7 cases of bilateral fractures. Five sides were type A fractures and 22 sides were type B. There were 14 simple diacapitular condylar fractures, 12 diacapitular condylar fractures combined with mandibular chin fractures, and 1 diacapitular condylar fracture combined with mandibular angle fracture. The maximum opening was 5-20 mm (mean, 9.7 mm). The time from injury to operation was 4-20 days, with an average of 11.6 days. The postoperative imaging examination was performed to evaluate the reduction of fracture and disc. The maximum opening at 6 months after operation was recorded, and the clinical dysfunction index (Di) of Helkimo index was used to evaluate the temporomandibular joint function. Results All incisions healed by first intention. All 20 patients were followed up 6-10 months (mean, 8 months). Postoperative imaging examination showed that 27 fractures were well reduced, of which 26 were anatomically reduced and 1 was basically reduced; the reduction of the temporomandibular joint disc was excellent in 25 sides, good in 1 side, and poor in 1 side, and the effective rate of disc reduction and anchorage was 96.3%. The occlusion relationship of the patient was stable and basically reached the pre-injury level, the incision scar was hidden, and the mouth opening significantly improved when compared with the preoperative level. The maximum mouth opening was 32-40 mm (mean, 36.8 mm) at 6 months after operation. Maximum opening was more than 35 mm in 17 cases. At last follow-up, joint function reached Di 0 grade in 8 sides, DiⅠ grade in 18 sides, and DiⅡ grade in 1 side. After operation, 2 cases of opening deviation, 1 case of joint click, and 2 cases of temporary disappearance of frontal striae on affected side occurred, which recovered to normal after symptomatic treatment. ConclusionFor diacapitular condylar fractures with disc displacement, it is necessary to adopt disc reduction and anchorage at the same time of fracture reduction and internal fixation, which can achieve good clinical results.
Objective
To study the short-term effectiveness of absorbable anchor in repairing of partial anterior cruciate ligament (ACL) rupture.
Methods
Between December 2013 and February 2015, 22 patients with partial ACL rupture were repaired with absorbable anchor under arthroscopy. There were 12 males and 10 females with an average age of 27.5 years (range, 20-44 years). The injury located at left knee in 8 cases and at right knee in 14 cases. The time from injury to admission ranged from 2 to 13 days (mean, 9.8 days). Sixteen partial ACL ruptures combined with meniscus injury. The effectiveness was assessed by Tegner score, Lysholm score, International Knee Documentation Committee (IKDC) score, visual analogue scale (VAS) score, and MRI, as well as knee laxity was evaluated by KT-1000.
Results
All incisions healed at stage Ⅰ without any complication. All patients were followed up 12 months. ACL rerupture did not occurred during follow-up. There was no significant difference in Tegner score, Lysholm score, and IKDC score between before injury and at 12 months after operation (P>0.05). And the median satisfaction VAS score was 9.5 (range, 9-10). The tibial anterior translation difference was 0.5 mm (range, 0-6 mm). MRI showed that the scarring and continuity of the ligament were rated as grade 1 in all patients.
Conclusion
Arthroscopic repairing by absorbable anchor is a feasible method for partial ACL rupture, with ideal knee function, good satisfaction, and satisfactory short-term effectiveness.
ObjectiveTo explore the effectiveness of non-absorbable suture or suture anchor fixation by anterior approach in the treatment of anteromedial facet fractures of the ulnar coronoid process.
MethodsBetween February 2007 and February 2012,16 cases of anteromedial facet fractures of the ulnar coronoid process were treated with operation.There were 9 males and 7 females,aged 20-80 years (mean,43.5 years).The causes of injury were traffic accident injury in 7 cases,tumble injury in 5 cases,and falling injury from height in 4 cases.The time from injury to operation was 6.8 days on average (range,2-8 days).All cases had closed fractures.According to O'Driscoll classification,there were 4 cases of type Ⅱ a,7 cases of type Ⅱ b,and 5 cases of type Ⅱ c.Among 16 patients,7 had simple anteromedial facet fractures of the ulnar coronoid process,and 9 had associated injury,including terrible triad in 3,Monteggia fractures in 4,and olecranon fractures in 2.All fractures were fixed with non-absorbable suture in 10 cases,and with suture anchor in 6 cases.The Mayo Elbow Performance Score (MEPS),range of motion (ROM),and complications were used to assess the elbow function.
ResultsThe incisions all healed by first intension,without neurovascular injury.Fifteen patients were followed up 10-48 months (mean,25.3 months).The X-ray films showed that all fractures healed,with the mean healing time of 17.5 weeks (range,11-30 weeks).At last follow-up,the mean MEPS score was 88.5(range,55-100);the results were excellent in 10 cases,good in 3 cases,fair in 1 case,and poor in 1 case,with an excellent and good rate of 86.7%.The mean ROM of flexion and extension was 118°(range,35-145°),and the mean ROM of forearm rotation was 138°(range,85-165°).One case had elbow instability,and 3 had slight pain.No heterotopic ossification and traumatic arthritis occurred during the follow-up.
ConclusionThe anteromedial facet fractures of the ulnar coronoid process can be clearly exposed through anterior approach,and the fracture fixation using non-absorbable suture and suture anchor fixation usually can restore the elbow function.
ObjectiveTo evaluate the effectiveness of the channel-assisted minimally invasive repair (CAMIR) technique combined with flexor hallucis longus (FHL) tendon transfer in the treatment of Achilles tendon sleeve avulsion. Methods A retrospective analysis was conducted on 17 patients with Achilles tendon sleeve avulsion who underwent CAMIR technique combined with FHL transfer between January 2019 and January 2023. The cohort comprised 13 males and 4 females, aged 32 to 65 years (mean, 49.7 years). Etiologies included sports-related injuries in 15 cases and blunt trauma in 2 cases. The interval from injury to surgery ranged from 4 to 368 days (median, 15 days). All patients exhibited calcification at the Achilles tendon insertion site, with 7 cases complicated by Haglund deformity. Postoperative complications were meticulously monitored, and tendon healing was assessed via MRI. Clinical outcome were evaluated using the visual analogue scale (VAS) score for pain, Tegner activity level rating scale, ankle activity score (AAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, Victorian Institute of Sport Assessment-Achilles (VISA-A) score, and subjective clinical scoring systems preoperatively and at last follow-up. Results The operation time was 50-62 minutes (mean, 56 minutes), and the intraoperative blood loss was 5-50 mL (mean, 19.7 mL). All patients were followed up 12-67 months (mean, 38 months). No postoperative complication, such as Achilles tendon re-rupture, incision infection, deep vein thrombosis, heel raise insufficiency, or sural nerve injury, was observed. At last follow-up, MRI examination confirmed satisfactory tendon healing in all cases. Significant improvements were noted in VAS scores, Tegner activity level rating scale, AAS scores, AOFAS ankle-hindfoot scores, and VISA-A scores compared to preoperative ones (P<0.05). At last follow-up, the subjective clinical score ranged from 6 to 10 (median, 9).ConclusionThe CAMIR technique combined with FHL tendon transfer is a good treatment for repair of Achilles tendon sleeve avulsion, with good recovery of ankle function and few complications.
Objective A multicenter, randomized, single-blind, parallel-controlled noninferiority study was used to evaluate the short-term safety and effectiveness of domestic polyether-ether-ketone (PEEK) suture anchor for rotator cuff repair by comparing with the imported PEEK suture anchor commonly used in clinical practice. Methods A total of 59 patients with rotator cuff tears who were admitted between May 2019 and October 2019 were selected as the research objects. Among them, 3 patients were excluded because they did not meet the selection criteria, and 1 patient withdrew from the study because of serious adverse events. A total of 55 patients were included in the study. They were randomly divided into trial group (n=27) and control group (n=28). The trial group used PEEK suture anchors produced from REJOIN Company, and the control group used PEEK suture anchors from American Arthrex Company. Two patients in control group were lost to follow-up. Twenty-seven patients in trial group and 26 patients in control group were included in the final quantitative analysis. There was no significant difference (P>0.05) in gender, age, disease duration, side and sizes of rotator cuff tears, composition ratio of patients with type 2 diabetes, and preoperative American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, University of California at Los Angeles (UCLA) score, and visual analogue scale (VAS) score. The patients were followed up regularly after operation. The postoperative follow-up included safety evaluation (complications, anchor position, and anchor bone reaction) and effectiveness evaluation (shoulder joint function and pain scores, rotator cuff integrity based on Sugaya classification criteria). Results The operations in both groups were successfully completed, and there was no complication related to the operation and suture anchor. All incisions healed by first intention. There was no significant difference in follow-up time between trial group [(5.85±0.77) months] and control group [(5.96±0.72) months] (t=0.535, P=0.595). MRI examination indicated that the repaired tendons were fixed and the anchors did not get loose or torn. At 1 day, 3 months, and 6 months after operation, there was no patient with grade 3-4 anchor bone reaction in the two groups, and there was no significant difference in the bone reaction grading between groups (P>0.05). After operation, the VAS scores of the two groups gradually decreased, and the ASES scores, Constant-Murley scores, and UCLA scores gradually increased, and there were significant differences between groups at each time point (P<0.05). There was no significant difference between groups at different time points (P>0.05). There was no significant difference in Sugaya classification of rotator cuff integrity at 1 day, 3 months, and 6 months after operation between groups (P>0.05). Conclusion The short-term safety and effectiveness of domestic PEEK suture anchors in rotator cuff tear repair are not significant different from those of imported PEEK suture anchors commonly used in clinical practice.
