Reverse design of a new type of low-profile lateral malleolus steel plate assisted by computer bioengineering technology / 中国组织工程研究

BACKGROUND:Poor incision healing and infection often occur in elderly patients with lateral malleolar fractures after traditional lateral plate fixation.With the application of engineering software in medicine,a new type of plate placed posterolateral can be designed to solve the above-described problems. OBJECTIVE:To design a new type of posterior lateral low-profile steel plate with the aid of medical bioengineering software,based on the 3D CT data of the distance between the top of the lateral ankle fracture line to the anterior starting point(ACD),the distance between the top of the fracture line to the tip of the lateral ankle(CTD),the distance between the top of the fracture line to the posterior edge of the fracture line(PCD)and the angle between the anterior and posterior lateral sides of the distal fibula(CA). METHODS:Thirty cases of unstable lateral malleolar fracture and normal ankle were taken for CT scanning and three-dimensional reconstruction.The ACD,CTD,and PCD values in patients with lateral malleolar fracture were measured by 3-matic software,and the characteristics of lateral malleolar fracture line were plotted and described.The mimics software was used to measure the value of CA in the normal ankle joint.Based on the data measured above,3-matic software and solidworks software were used to design the low-profile steel plate and the thickness of the steel plate and the direction of the nail path were constructed.In Geomagic Studio software,fine surface,automatic surface,and fitting surface were used to generate the prototype of the low-profile steel plate,and then 3D printing was performed.After making a posterolateral incision of the lateral malleolus,the peroneus longus and brevis tendons were removed,and the prototype of the 3D-printed steel plate was placed behind the fibula to test its size and fit to the bone surface. RESULTS AND CONCLUSION:(1)The mean of ACD was(2.97±0.03)cm,and the variation was 5.23.The mean of PCD was(3.17±0.11)cm,and the variation was 17.60.The mean of CTD was(4.52±0.07)cm,and the variation was 8.60.(2)The fracture line of the lateral malleolus was drawn with an inverted"V"shape.The mean of CA between anterior and posterior lateral surfaces of the distal fibula was(103.20±1.94)°.At the midpoint section of the upper and lower vertices of the anterior edge of the distal fibula,the angle of the anterior and posterior lateral sides(CA)of the distal fibula was(78.50±1.78)°.(3)By using 3-matic,Solidworks,and Geomagic Studio software,a new type of posterior lateral low-profile steel could be successfully designed.Three to four holes were reserved for the screw holes at the proximal end of the plate with screw directions from back to front,and three screw holes were reserved on the inner and outer sides at the far end.The direction of the inner three holes could be from back to front,and the outer three screw holes needed to be biased towards the inner side,with an angle of 9.72°-13.28°.(4)It is indicated that the variability of the ACD position on the anterior lateral fracture line of the lateral malleolus is relatively small,while the variability of the posterior lateral PCD position is relatively large.The angle between the anterolateral and posterolateral sides of the lateral ankle fracture block shows a decreasing trend,with a smaller variation in the proximal angle and a larger variation in the distal angle.Based on three-dimensional CT reconstruction data of the external ankle,with the help of computer bioengineering software and the use of reverse design concept,a new type of low-profile lateral malleolus steel plate with a good fit can be quickly and conveniently designed to provide a valuable reference for the design of internal fixation devices.

Clinical efficacy of CT modeling and 3D printing in the treatment of ankle fracture / 中国综合临床

Objective:To explore the effect of 3D printing technology on ankle fracture surgery.Methods:This study was a case-control study.Forty five patients with ankle fractures admitted to the Department of Orthopaedics of the Affiliated Hospital of North China University of Science and Technology from January 2017 to May 2022 were selected. Divide into an observation group and a control group using the random number table method. The control group received open reduction and internal fixation of the ankle joint under X-ray assistance, while the observation group used Mimics software modeling and 3D printing models to assist in open reduction and internal fixation of the ankle joint. Compare the surgical time, intraoperative bleeding volume, intraoperative X-ray exposure frequency, postoperative physician fatigue scale 14 (FS-14) score, fracture reduction quality, fracture healing time, and ankle joint function at 6 months after surgery between the two groups of patients. The measurement data is represented by ± s, and the two groups are compared using t-tests with two independent samples; Counting data is represented by examples (%), χ 2 test is used for inter group comparison, and rank sum test is used for inter group comparison of rank data. Results:The observation group had shorter surgical time than the control group [(134.16±25.61) minutes compared to (163.38±41.90) minutes], with less intraoperative bleeding and fewer intraoperative X-ray exposure times than the control group [(46.32±29.29) mL compared to (99.62±77.85) mL, (13.68±3.50) times compared to (18.54±6.09) times], and lower postoperative physician fatigue scores than the control group [(9.77±2.02) points compared to (12.13±1.73) points], The differences between groups were statistically significant (t-values in decibels were 2.69, 3.20, 3.12, and 4.20, all P<0.05). The quality of postoperative fracture reduction in the observation group was excellent in 12 cases, good in 5 cases, and poor in 2 cases; The quality of postoperative fracture reduction in the control group was excellent in 7 cases, good in 16 cases, and poor in 3 cases. Compared between groups, the observation group had better postoperative fracture reduction quality than the control group ( Z=-2.05, P=0.040). At a follow-up of 6 months after surgery, there was no statistically significant difference in bone healing time between the two groups ( P>0.05). The AOFAS score in the observation group was higher than that in the control group (91.63±2.83) compared to (88.92±3.92), and the difference was statistically significant ( t=2.56, P=0.014). Conclusions:Using Mimics software modeling and 3D printing technology to assist ankle fracture surgery can shorten the operation time, reduce the use rate of X-ray, reduce the fatigue of doctors, and improve the quality of joint reduction and ankle function.

Fracture Classification and Injury Segment Analysis of Tibiofibula and Ankle in Half-Squat Parachuting Landing / 医用生物力学

Objective To make classification and segment measurement for the cases with tibiofibular and ankle fractures in parachuting landing, and investigate main classification types of parachuting fractures and fracture segments of high risk.Methods A total of 56 fracture cases in parachuting landing were collected, and the tibiofibula and ankle fractures were classified according to AO-OTA or Lauge-Hansen classification standards respectively based on their digital X-ray images. The medium plane between talus and tibia joint planes in ankle joint was defined as the reference plane. The highest and lowest injury points of tibia and fibula were marked respectively, and the fracture segment was defined between the highest and lowest point for statistical analysis.Results For tibiofibular and ankle fracture cases in parachuting landing, fracture at both tibia and fibula accounted for 80.4%. The major classification of tibiofibula fracture was 42-D/5.2 (45.8%) and 42-D/5.1 (16.7%). The major classification for ankle fracture was pronation-external rotation (PER, 59.4%) and supination-external rotation (SER, 37.5%). When tibiofibular and ankle fracture cases in parachuting landing occurred, the fracture segment of the tibia was mainly from 57 to 143 mm above the reference plane and from 6 mm below the reference plane to 24 mm above the reference plane, while the fracture segment of the fibula was 4-45 mm and 74-83 mm above the reference plane. Injury risks of all above segments were higher than 50%.Conclusions For protection of lower limbs in parachuting landing, the fracture at both tibia and fibula should be highly noticed. The ankle motion of PER and SER should be especially restricted in parachuting ankle protection.

Eeffect of ultra-low dose CT scanning on the diagnosis of ankle fracture and the quality of a three-dimensional printing model / 中华放射医学与防护杂志

Objective:To investigate the effect of ultra-low dose (ULD) computed tomography (CT) scanning on the diagnosis of ankle fractures and the quality of a three-dimensional printing (3DP) model.Methods:This study was a prospective study. A total of 61 patients with clinical ankle fractures treated conservatively in Zhuhai Hospital of Guangdong Hospital of Traditional Chinese Medicine from November 2019 to January 2022 were included in this study. Patients underwent standard dose (SD) CT scan and ultra-low dose (ULD) CT scan, respectively. The tube voltage/tube current of SD and ULD were 120 kV/100 mAs and 80 kV/10 mAs, respectively. Two senior radiologists evaluated the presence of ankle fractures. The effective radiation dose ( E), noise, signal-to-noise ratio (SNR), contrast signal-to-noise ratio (CNR), and CT value of bone cortex minus CT value of peripheral fat (CTc) were compared. The radiologists also evaluated the discoverability, diagnosability, and overall image quality of the fracture line according to Likert′s 5-point scoring method. Two senior orthopedists subjectively evaluated the quality of each 3DP model (model clarity and operation guidance). A score ≥ 3 indicated that the quality of the CT diagnostic image and 3DP model were acceptable. Results:The interval between the two CT scans was (9.23 ± 1.92) d. A total of 94 fracture sites were found. There were no missed diagnosis or misdiagnosis based on the SD and ULD scans.Noise, SNR, and CNR were better on the SD CT scanning ( F=5.92, 9.70, 8.32, P=0.00), however, CTc was higher on the ULD scans ( F=27.55, P<0.01). The image scores of the SD and ULD scans were (4.97 ± 0.18) and (4.21 ± 0.71), and the quality scores of the 3DP model (4.99 ± 0.01) and (4.87 ± 0.34), respectively. The SD scans were better than the ULD scans with respect to CT image quality and 3DP model quality ( Z=-6.88, -2.91, P<0.01), but both were considered suitable to meet clinical needs (all ≥ 3 points). The E associated with SD and ULD scannings were (34.68 ± 4.96) μSV and (1.04 ± 0.10) μSV, respectively. The latter was thus significantly better than the former ( F=38.77, P =0.00). Conclusions:The E value of ULD scanning is about 3.00% of SD scanning E, which can meet the needs of clinical diagnosis of ankle fracture and 3DP model printing diagnosis.

Predictors of Functional Outcome in Unstable Ankle Fractures Treated Surgically – A Prospective Cohort Study

@#Introduction: Unstable ankle injuries require anatomical reduction and stabilisation for optimal outcome. In spite of adequate care, a few patients have poor outcome. In this study, we assessed the risk factors that predict the clinical outcomes in surgically treated unstable ankle fractures. Material and methods: This prospective cohort study was conducted on 68 patients who underwent surgical management for an unstable ankle injury. Demographic details, fracture type and associated medical comorbidities were recorded. Pre-operative radiographic assessment was done for all patients. At the end of one year follow-up, clinical (American Orthopaedic foot and ankle societyAOFAS and Olerud-Molander ankle - OMAS) scores and radiological parameters were assessed and analysed. Results: Fracture dislocation (0.008), diabetes mellitus (0.017), level of alchohol consumption (0.008) and preoperative talocrural angle (TCA) > 100° (0.03) were significant predictors of poor outcomes as per AOFAS. Fracture dislocation (0.029), diabetes mellitus (0.004), preoperative TCA > 100° (0.009), female gender (0.001), age more than 60 years (0.002) and open injuries (0.034) had significantly poor outcome as per OMAS. Other parameters (smoking, hypertension, classification, syndesmotic injury, medial clear space and tibiofibular overlap) did not affect the outcome significantly. Conclusion: Our study showed that poor outcome predictors in unstable ankle fractures are age >60 years, female gender, diabetes mellitus, alcohol consumption, fracture dislocation, open fractures and pre-op TCA >100°.

Effectiveness of repairing the deep layer of deltoid ligament by suture anchor repair method in treatment of mixed medial injury associated with ankle fractures / 中国修复重建外科杂志

Objective: To explore the necessity of repairing the deep layer of deltoid ligament in the treatment of mixed medial injury associated with ankle fractures. Methods: Between January 2016 and December 2018, 12 patients with mixed medial injury associated with ankle fractures were treated with the fixation of the lateral malleolus by bone plates, the fixation of the anterior colliculus of medial malleolus by cannulated screws, and the repair of the deltoid ligament by suture anchors. There were 8 males and 4 females, with an average age of 42 years (range, 18-56 years). According to the Lauge-Hansen classification criteria, there were 11 cases of supination-external rotation type and 1 case of pronation-external rotation type. According to the Weber classification criteria, all cases were type B. The time from injury to operation was 3-6 days, with an average of 4.7 days. In each patient, X-ray films of anteroposterior and lateral views and mortise view of ankle were taken postoperatively. The motion range of ankle joints was observed. The function of the ankle and the outcome of the treatment were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system, Olerud-Molander scoring system, and the visual analogue scale (VAS) score. Results: All cases were followed up 12-42 months (mean, 28 months). The 12 patients returned to their pre-injury jobs. Five patients with sports injury completely recovered to their pre-injury motor function. No patient experienced persistent medial ankle pain or ankle instability. At last follow-up, the ankle range of motion in dorsiflexion was 9°-25° (mean, 17.96°), which was 0°-11° (mean, 4.02°) less than that in normal side; the range of motion in plantar flexion was 38°-50° (mean, 43.90°), which was 0°-7° (mean, 2.53°) less than that in normal side. The AOFAS score was 88-100 (mean, 96.7); the Olerud-Molander score was 90-100 (mean, 96.5); the VAS score was 0-3 (mean, 1.1). Conclusion: It is necessary to repair the deep layer of deltoid ligament in the mixed medial injuries associated with ankle fracture, which include anterior colliculus fracture and deep deltoid ligament injury. A better outcome can be achieved by employing the suture anchor repair method.

Clinical analysis of full-repair strategy under small incision for closed Lauge-Hansen pronation-external rotation type Ⅳ ankle fracture / 中国修复重建外科杂志

Objective: To investigate the safety, feasibility, and efficacy of full repair strategy under small incision in the treatment of closed Lauge-Hansen pronation-external rotation type Ⅳ ankle fracture. Methods: The clinical data of 57 patients with closed Lauge-Hansen pronation-external rotation type Ⅳ ankle fracture treated by full repair strategy (fracture, ligament, and cartilage repair) under small incision between January 2012 and January 2017 were retrospectively analyzed. There were 31 males and 26 females, with an average age of 41.1 years (range, 21-65 years). The causes of injury included traffic accident injury in 33 cases and falling injury in 24 cases. All of them were closed fractures, including 20 cases of medial malleolus fracture, 37 cases of complete medial malleolus but deep and shallow rupture of deltoid ligament. The average time from injury to admission was 9.6 hours (range, 3-34 hours). The quality of reduction of distal tibial articular surface (based on Ketz-Sanders standard), the reduction of tibiofibular syndesmosis (the anterior and posterior distances of distal tibiofibular syndesmosis and the lateral ankle twist angle measured by CT scan at 10 mm above the ankle joint line), and the fracture healing were evaluated. The medial clear space (MCS), tibiofibular clear space (TFCS), and distal fibular tip to lateral process of talus (DFTL) were measured on the X-ray films of ankle points. Before and after operation, the pain and functional improvement of ankle joint were evaluated by visual analogue scale (VAS) score and American Orthopedic Foot and Ankle Association (AOFAS) score, and the activities of ankle dorsiflexion and plantar flexion were measured. Results: Three cases with osteochondral lesions of the talus were found during operation and all were treated with microfracture techniques. Tournament paralysis occurred in 2 cases after anesthesia. The surgical incisions healed by first intention in all patients. All the 57 patients were followed up 24-84 months, with an average of 38.6 months. All patients achieved bone healing without bone nonunion and malunion at 12 months after operation. The reduction quality of distal tibial articular surface was excellent in 56 cases and good in 1 case at 3 months after operation, the excellent and good rate was 100%. There was no significant difference in the MCS, TFCS, DFTL, anterior distance of distal tibiofibular syndesmosis, posterior distance of distal tibiofibular syndesmosis, and lateral ankle twist angle between the affected and healthy sides at 12 months after operation ( P>0.05). At last follow-up, the VAS score, AOFAS score, ankle dorsiflexion and plantar flexion activities of the affected side were significantly improved when compared with preoperative ones ( P0.05). Conclusion: Full-repair strategy under small incisions for the treatment of Lauge-Hansen pronation-external rotation type Ⅳ ankle fracture is effective and safe. It can not only reduce wound complications, but also improve the quality of joint reduction of the ankle joint and distal tibiofibular syndesmosis. Full repair of ligaments and cartilage can improve the internal fixation strength and joint stability of the ankle joint.

Haste intramedular de fíbula nas fraturas maleolares do tornozelo - técnica cirúrgica e revisão da literatura / Intramedullary nailing of lateral malleolus in ankle fractures - surgical technique and literature review

RESUMO Nosso objetivo é descrever a técnica de fixação intramedular (IM) da fíbula no tratamento cirúrgico das fraturas maleolares do tornozelo. A redução é realizada sempre de forma percutânea: quando o traço de fratura é oblíquo simples, utilizamos uma pinça de redução de pontas e quando a fratura apresenta padrão multifragmentar, usa-se tração longitudinal e rotação. Isso reduz as complicações relacionadas à redução aberta e fixação interna com placa. A técnica demonstrou ser simples e reprodutível. Além disso, essa forma de fixação permite apoio precoce do peso corporal, o que acelera o processo de reabilitação e potencialmente acelera a cicatrização da fratura. A fixação IM da fíbula mostrou-se uma opção viável para a fixação do maléolo lateral nas fraturas do tornozelo, devendo ser considerada no arsenal do cirurgião.

ABSTRACT Our objective is to describe the technique of intramedullary (IM) nailing of lateral malleolus in the surgical management of ankle fractures. Fracture reduction is performed either percutaneously with a small pointed reduction clamp in simple oblique fractures or using longitudinal traction and rotation for comminuted fractures, thus reducing complications related to open reduction and internal fixation with a plate. The technique has been shown to be simple and reproducible. In addition, the technique allows early weight bearing, which accelerates rehabilitation and potentially fasten fracture healing. IM nailing is a viable option for the fixation of the of lateral malleolus in ankle fractures and should be considered in the surgeon's armamentarium.

Prevalence and associated factors of intra-articular lesions in acute ankle fractures evaluated by arthroscopy and clinical outcomes with minimum 24-month follow-up / 中华医学杂志(英文版)

Background@#Acute ankle fractures can lead to high rate of concomitant intra-articular lesions which may compromise clinical results. The purpose of this study was to evaluate the Prevalence of concomitant intra-articular lesions in acute ankle fractures with arthroscopy. We also sought to analyze the relationship between intra-articular lesions and the fracture type, as well as the severity of the fracture.@*Methods@#It was a retrospective cohort study. From April 2014 to December 2015, we have chosen arthroscopy-assisted open reduction and internal fixation (AORIF) for the treatment of unstable acute ankle fractures. All concomitant intra-articular lesions were assessed and documented carefully and prospectively, such as ligament injuries, osteochondral lesions, and tibiofibular syndesmosis injuries. All fractures were classified according to the Lauge-Hansen classification system. The American Orthopedic Foot and Ankle Society’s (AOFAS) ankle-hindfoot scale was used to assess post-operative function. Statistical comparisons between the intra-articular lesions, the fracture type, and the severity of the presenting fracture were performed using a Chi-squared analysis.@*Results@#Data of 36 patients were analyzed in the study, including 23 supination-type fractures and 13 pronation-type fractures. The incidence of tibiofibular syndesmosis injuries, chondral lesions, and loose bodies were 92%, 72%, and 39%, respectively. Avulsion fractures of the anterior tibiofibular syndesmosis were more commonly found in supination-type fractures than pronation-type fracture (45% vs. 15%, χ2 = 5.78, P = 0.02), which would cause mechanical blocking in the anterior portion of the ankle. On the contrary, chondral lesions were more commonly found in the more severe fractures than mild fractures (86% vs. 53%, χ2 = 4.57, P = 0.03). A mean 41.7 months (range, 33.0–51.0 months) of follow-up was achieved. A mean AOFAS’s ankle-hindfoot scale was 96.9, and 97.2% of the patients were satisfied with the procedure.@*Conclusions@#Acute ankle fractures have a high incidence of concomitant intra-articular lesions. Avulsion fractures of the anterior tibiofibular syndesmosis are more commonly found in supination-type fractures. Chondral lesions are related to the severity of the fractures, but not with the classification of the fractures. AORIF can be one reliable solution in dealing with the associated injuries seen with acute ankle fractures.

Fractura de Tillaux en adultos en asociación con las fracturas de Volkmann y Maisonneuve. Reporte de caso / Adult Tillaux fracture in association with Volkmann and Maisonneuve fractures. Case report

Se sabe que la fractura de Tillaux ocurre en adolescentes una vez que ocurre durante el período de transición cuando la fisis medial y central ha finalizado el cierre, pero la fisis lateral todavía está abierta. El mecanismo de traumatismo es típicamente una lesión de tobillo de rotación externa que resulta en una fractura por avulsión del plafón tibial anterolateral. Esta fractura rara vez se ha informado en adultos, especialmente asociada con otras lesiones. Divulgamos un caso de fractura de Tillaux en un adulto, asociado con una fractura de Volkmann y una fractura de Maisonneuve, que se trataron mediante cirugía con reducción abierta y fijación interna y tuvieron un resultado excelente. Reconocer y tratar apropiadamente cada una de estas lesiones es la clave para prevenir artritis e inestabilidad degenerativas.

Tillaux fracture is known to occur in adolescents once it happens during transition period when the medial and central physis has finished closure, but the lateral physis is still opened. The trauma mechanism is typically external rotation ankle injury resulting in an avulsion fracture of the anterolateral tibial plafond. This fracture has rarely been reported in adults, especially associated with others injuries. We report a case of Tillaux fracture in an adult, associated with a Volkmann fracture and a Maisonneuve fracture, that were surgery treated with open reduction and internal fixation and had an excellent outcome. Recognize and appropriately treat each one of these injuries is the key to prevent further degenerative arthritis and instability.

Reproducibility of the Lauge-Hansen, Danis-Weber, and AO classifications for ankle fractures / Análise da reprodutibilidade das classificações de Lauge-Hansen, Danis-Weber e AO para as fraturas de tornozelo

ABSTRACT Objective: This study evaluated the reproducibility of the three main classifications of ankle fractures most commonly used in emergency clinical practice: Lauge-Hansen, Danis-Weber, and AO-OTA. The secondary objective was to assess whether the level of professional experience influenced the interobserver agreement for the classification of this pathology. Methods: The study included 83 digitized preoperative radiographic images of ankle fractures, in anteroposterior and lateral views, of different adults that had occurred between January and December 2013. For sample calculation, the estimated accuracy was approximately 15%, with a sampling error of 5% and a sampling power of 80%. The images were analyzed and classified by six different observers: two foot and ankle surgeons, two general orthopedic surgeons, and two-second-year residents in orthopedics and traumatology. The Kappa statistical method of multiple variances was used to assess the variations. Results: The Danis-Weber classification indicated that 40% of the agreements among all observers were good or excellent, whereas only 20% of good and excellent agreements were obtained using the AO and Lauge Hansen classifications. The Kappa index was 0.49 for the Danis-Weber classification, 0.32 for Lauge Hansen, and 0.38 for AO. Conclusion: The Hansen-Lauge classification presented the poorest interobserver agreement among the three systems. The AO classification demonstrated a moderate agreement and the Danis-Weber classification presented an excellent interobserver agreement index, regardless of professional experience.

RESUMO Objetivo: Avaliar a reprodutibilidade e comparatividade das três principais classificações usadas para fraturas do tornozelo mais comumente empregadas nos servicos de emergência: Lauge-Hansen, Danis-Weber e AO-OTA. Observar secundariamente se existe influência da experiência profissional sobre a concordância entre observadores para a classificação dessa patologia. Métodos: Foram usadas 83 imagens digitalizadas de radiografias pré-operatórias, em incidências anteroposterior e perfil, de fraturas do tornozelo de adultos diferentes, ocorridas entre janeiro e dezembro de 2013. No cálculo amostral assumiu-se precisão da estimativa de 15%, com erro amostral de 5% e com poder de amostragem de 80%. A leitura e a classificação das fraturas foram feitas por seis observadores, dois cirurgiões de pé e tornozelo, dois ortopedistas generalistas e dois residentes do segundo ano de ortopedia e traumatologia. A análise das variações foi feita pelo método estatístico de Kappa de múltiplas variâncias. Resultados: Com o uso da classificação de Dannis-Weber, 40% das concordâncias foram consideradas boas ou excelentes entre todos os observadores, enquanto nas classificações de Lauge Hansen e AO apenas 20% se apresentaram boas ou excelentes. O índice Kappa acumulado para cada classificação foi de 0,49 para a classificação de Dannis-Weber, 0,32 para Lauge Hansen e 0,38 para a classificação AO. Conclusão: A classificação de Lauge Hansen apresenta a pior concordância interobservador dentre as três classificações. A classificação da AO demonstrou concordância intermediária e a de Dannis-Weber apresentou o maior índice de concordância interobservador, independentemente da experiência do profissional.

Comparision between Syndesmotic Screw Fixation and Knotless Tightrope® Fixation on Ankle Fractures with Distal Tibiofibular Syndesmosis Injury / 대한족부족관절학회지

PURPOSE: A distal tibiofibular syndesmosis injury with an ankle fracture is usually fixed with syndesmotic screws. Knotless Tightrope® has been used as an alternative procedure because of the fewer reported complications. Therefore, this study compared the two surgeries. MATERIALS AND METHODS: Forty-two patients, who underwent syndesmotic screw fixation, and 34 patients, who underwent Knotless Tightrope® fixation for distal tibiofibular syndesmosis injury from February 2014 to February 2016, were analyzed retrospectively. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, range of motion of ankle at 1 year after surgery, tibiofibular clear space, and tibiofibular interval at preoperative, postoperative and 1 year after surgery were investigated. RESULTS: The VAS score, AOFAS score and radiographs were similar in the two groups. Knotless Tightrope® showed better results in complications and plantarflexion. CONCLUSION: Knotless Tightrope® fixation is a useful treatment that does not show a difference in fixation strength and clinical outcome. Knotless Tightrope® fixation also has an advantage in the range of motion and complications.
