ABSTRACT

Introducción: La artrodesis tibioastragalina es una opción para tratar la artrosis de tobillo en pacientes que no responden a las medidas conservadoras. Su principal desventaja es el compromiso a mediano y largo plazo de las articulaciones vecinas. Objetivo: Determinar el compromiso de las articulaciones vecinas a mediano y largo plazo, y su impacto sobre los resultados funcionales en los pacientes con artrodesis de tobillo. Materiales y Métodos: Se evaluó a una serie de 11 pacientes (6 mujeres y 5 hombres). El diagnóstico inicial era artrosis postraumática (9 casos), artritis séptica (1 caso) y lesión osteocondral de astrágalo (1 caso). El promedio de edad al operarse era de 50 años. La media de seguimiento fue de 9 años. Se evaluó el compromiso radiográfico de las articulaciones vecinas. La función se valoró mediante la escala analógica visual para dolor, la escala de la AOFAS y un cuestionario simple de satisfacción. Resultados: Diez pacientes (91%) tenían artrosis en alguna de las articulaciones vecinas. El puntaje medio en la escala analógica visual fue de 2,6 y el de la escala de la AOFAS, de 71. Nueve refirieron estar muy satisfechos; uno, medianamente satisfecho y otro se manifestó insatisfecho. Conclusión: El compromiso de las articulaciones vecinas es muy frecuente a largo plazo, pero esto no repercute directamente en los resultados funcionales. Nivel de Evidencia: IV


Introduction: Tibiotalar arthrodesis is an option in the treatment of ankle osteoarthritis in patients who do not respond to conservative measures. Its main disadvantage is the compromise of adjacent joints in the medium and long term. Objective: To determine the involvement of adjacent joints in the medium and long term and its impact on functional outcomes in patients with ankle arthrodesis. Materials and Methods: We evaluated a series of 11 patients, 6 females and 5 males. The initial diagnosis was post-traumatic osteoarthritis (9 cases), septic arthritis (1 case), and osteochondral lesion of the talus (1 case). The mean age at the time of surgery was 50 years. The mean follow-up was 9 years. The radiographic compromise of the adjacent joints was evaluated. The patients were functionally evaluated using the Visual Analog Pain Scale (VAS), the AOFAS scale (American Orthopedic Foot and Ankle Score), and a simple satisfaction questionnaire. Results: 10 patients (91%) presented with osteoarthritis of one of the adjacent joints. The average score on the VAS was 2.6, while on the AOFAS scale, it was 71. Nine patients reported being very satisfied, one was moderately satisfied, and one was dissatisfied. Conclusion: The involvement of adjacent joints is very frequent in the long term, but this does not have a direct impact on the patient's functional outcomes. Level of Evidence: IV

Introduction: Supramalleolar osteotomies are a treatment option for asymmetric ankle osteoarthritis. Our work aims to describe the clinical, radiographic, and subjective outcomes obtained in patients with ankle osteoarthritis who underwent a supramalleolar osteotomy (SMOT). Materials and methods: Retrospective, observational, and descriptive study on patients who underwent SMOT for ankle osteoarthritis between January 2010 and July 2017. The patients' clinical records were analyzed. Results: We included 13 patients who underwent SMOT, 8 patients with valgus (61.5%) and 5 (38.5%) with varus rearfoot and ankle misalignment. The mean varus VAS score decreased from 9 ± 0.45 to 3 ± 1 postoperatively (p <0.05) and, in valgus deformities, from a mean 7.88 ± 0.35 to 2.15 ±1.64 postoperatively (p <0.05). The mean AOFAS score changed from 32.8 ± 16.2 to 82.1 ± 13.6 postoperatively in the varus deformity group (p <0.05) and from 31 ± 17.3 preoperatively to 93.1 ± 6.20 postoperatively in the valgus deformity group (p <0.05). Twelve patients (92.3%) achieved radiographic union in an average time of 10.4 weeks. Conclusion:Supramalleolar osteotomy as a treatment for asymmetric ankle osteoarthritis is a predictable technique with very good clinical and radiological outcomes in the short and medium term.

ABSTRACT

Introducción: La fractura de Maisonneuve es una lesión caracterizada por la fractura subcapital del peroné asociada a una lesión capsuloligamentaria de tobillo. Su tratamiento supone la restauración de la anatomía ósea y capsuloligamentaria normal para restablecer las fuerzas de contacto tibioastragalinas fisiológicas. Esta calidad de reducción puede ser difícil de alcanzar, sobre todo, con técnicas percutáneas. Objetivo: Evaluar mediante imágenes la calidad de la reducción de fracturas de Maisonneuve reducidas en forma cerrada (bajo visualización directa artroscópica) y fijadas por vía percutánea. Materiales y Métodos: Se analizaron radiografías e imágenes de tomografía computarizada preoperatorias y posoperatorias, comparativas de los tobillos operado y sano. Resultados: Se evaluaron 13 fracturas. Los parámetros radiográficos posoperatorios (espacio claro medial, solapamiento tibioperoneo distal, espacio claro tibioperoneo) no registraron diferencias, excepto por el intervalo tibioperoneo anterior que aumentó en un caso. La medición tomográfica posoperatoria del solapamiento tibioperoneo distal y el intervalo tibioperoneo anterior reveló que todas las reducciones eran satisfactorias. Dos pacientes tenían valores alterados en la sindesmosis tibioperonea distal con diferencia >2 mm respecto del tobillo sano. Conclusión: Recomendamos la asistencia artroscópica para el manejo de la fractura de Maisonneuve como herramienta de control intraoperatorio para una fijación percutánea más segura. Nivel de Evidencia: IV


Introduction: Maisonneuve fracture (MF) is an injury characterized by the subcapital fracture of the fibula associated with a capsuloligamentous injury of the ankle. Treatment involves the restoration of normal bone and capsuloligamentous anatomy in order to reestablish physiological tibiotalar contact forces. This quality of reduction can be difficult to achieve, especially with percutaneous techniques. Objective: To evaluate the quality of reduction in Maisonneuve fractures reduced in a closed manner (under direct arthroscopic visualization) and fixed percutaneously. Materials and Methods: We analyzed comparative preoperative and postoperative radiographs and CT scans of the operated and healthy ankles. Results: 13 fractures were evaluated. Radiographic parameters of postoperative procedures (medial clear space, distal tibiofibular overlap, tibiofibular clear space) did not register differences except for the anterior tibiofibular space, which had increased in 1 case. Postoperative tomographic measurements of tibiofibular clear space and anterior tibiofibular space showed 100% satisfactory reductions. Two patients presented altered distal tibiofibular overlap values with a difference greater than 2 mm compared to the healthy ankle. Conclusion: We recommend arthroscopy for the management of MF as an intraoperative control tool for safer percutaneous fixation. Level of Evidence: IV

ABSTRACT

Los defectos óseos segmentarios en la región del tobillo y el pie representan un desafío dadas sus características anatómicas con limitada vascularización y pobre cobertura muscular. La técnica descrita por Masquelet para el tratamiento de defectos óseos segmentarios en huesos largos ha logrado excelentes resultados. Sin embargo, se han publicado pocos estudios sobre su uso en la región del pie y tobillo. La técnica de la membrana inducida ofrece una alternativa terapéutica válida para resolver problemas de difícil solución en Ortopedia, como los defectos óseos. Permite tratarlos sin necesidad de procedimientos complejos, como el uso de injertos óseos vascularizados o de callotasis, con una alta tasa de consolidación, conservando la longitud del miembro y con una buena función. Entre enero de 2016 y diciembre de 2018, tres pacientes con defectos óseos segmentarios fueron tratados mediante la técnica de Masquelet en nuestra institución. Pese a que no podemos probar que este procedimiento es el más indicado en este tipo de casos, sí podemos afirmar que se logró la consolidación en todos los pacientes y se resolvió el defecto óseo, lo que nos anima a seguir utilizando esta misma técnica. Nivel de Evidencia: IV


Segmental bone defects in the foot and ankle represent a challenge due to their anatomical characteristics, limited vascularization, and poor muscle coverage. The technique described by Masquelet has shown excellent results for the treatment of segmental bone defects in long bones. However, there are few studies in the literature on its use in the foot and ankle. The induced membrane technique offers a valid treatment alternative to solve bone defects. It allows treatment without the need for complex procedures, such as vascularized bone grafts or distraction osteogenesis, with a high rate of consolidation, preserving the length and function of the limb. Although we cannot prove that this procedure is the most indicated for the treatment of bone defects, we can affirm that all our patients have achieved consolidation, which encourages us to continue performing this same technique.

ABSTRACT

El complejo ligamentoso lateral de la articulación talocrural o «tobillo» (CLT) contempla básicamente tres estructuras denominadas como ligamento talofibular anterior (LTFA), ligamento calcaneofibular (LCF) y ligamento talofibular posterior (LTFP). En los últimos artículos publicados en relación con la morfología del CLT, se clasifica al LTFA en tres tipos, basada en el número de bandas o fascículos. Esta variabilidad morfológica plantea nuevos desafíos de estudios anatómicos en la biomecánica y estabilidad de la región talocrural. El objetivo de este estudio fue profundizar la anatomía de este complejo, en base a disecciones por capa que nos permitan visualizar las relaciones existentes entre estos ligamentos y estructuras aledañas. Se utilizaron 10 piezas congeladas pertenecientes al Departamento de Anatomía y Medicina Legal de la Facultad de Medicina de la Universidad de Chile, cuyos ligamentos fueron localizados y medidos en ancho y longitud. Para el LTFA se observó un patrón único en 5 muestras, bifurcado en 4, mientras que en un caso se visualizó un patrón trifurcado. El conocimiento del complejo ligamentoso lateral de tobillo, así como de su dirección, biometría y bandas o fascículos son un importante aporte para la imagenología, rehabilitación, clínica y cirugías que aborden esta región.


SUMMARY: The lateral ankle complex (LAC) basically includes three structures called anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL) and posterior talofibular ligament (PTFL). In recent works published in relation to the morphology of LAC, ATFL is classified into three types, based on the number of bands or fascicles. This morphological modification poses new challenges for anatomical studies in biomechanics and ankle stability. The objective of this is to deepen in greater detail the anatomy of this complex, based on dissections by layer that allow us to study the existing relationships between these ligaments and surrounding structures. 10 frozen pieces belonging to the Department of Anatomy and Legal Medicine of the Faculty of Medicine of the University of Chile were used; whose ligaments were located and measured in width and length. For ATFL, a single pattern was found in 5 samples, bifurcated in 4, while a trifurcated pattern was seen in one case. Knowledge of the lateral ligamentous complex of the ankle, as well as its direction, biometry and bands or fascicles, are an important contribution to imaging, rehabilitation, clinics and surgeries that address this region.

El tiempo promedio hasta la toma del primer analgésico fue de 16 h. El grado de satisfacción del paciente con el bloqueo y el dolor percibido en las primeras 24 h fue: muy satisfecho (89%), satisfecho (10%) y poco satisfecho (1%). No hubo casos de secuela neurológica permanente, toxicidad sistémica ni infección. Conclusión:El bloqueo supramaleolar de tobillo es un método simple, eficaz y seguro que puede realizar el traumatólogo para obtener una analgesia posquirúrgica prolongada. Nivel de Evidencia: IV


Background: We present the description of a supramalleolar ankle block technique and our experience using this technique in foot and ankle surgery. Materials and methods: We performed a retrospective observational study of the past 5 years of patients with foot and ankle pathology that had undergone the supramalleolar ankle block. We excluded patients with a history of previous foot surgery, bilateral surgeries, vascular disease, peripheral neuropathy, diabetes, smoking, or active surgical site infection. The supramalleolar ankle block was guided by anatomic landmarks and we used a solution of lidocaine 2% and bupivacaine 0.5%. We evaluated the duration of the ankle block, the visual analog scale (VAS) for pain 24 hrs after surgery, the time until the first analgesic dose, and the level of patient satisfaction. Results:771 patients were included in this study, all of whom had complete analgesia for at least 12 hrs (mean 18 hrs) after surgery. The mean value on the VAS for pain after 24 hrs was 1.4. On average, the first analgesic dose was administered 16 hrs after surgery. The level of satisfaction about the pain perceived in the first 24 hrs after surgery was: very satisfied (89%), satisfied (10%), and dissatisfied (1%). There were no reports of permanent neurological sequelae, systemic toxicity, or surgical site infections. Conclusion: We consider the supramalleolar ankle block a simple, effective, and safe procedure to obtain long-lasting postoperative analgesia. Level of Evidence: IV

ABSTRACT

OBJECTIVE@#To investigate the difference in sensitivity between X-ray and three-dimensional reconstruction of computed tomography (3D-CT) for the diagnosis of distal fibular avulsion fracture, and the radiographic presentation of the ossicle.@*METHODS@#From January to October 2018, 92 patients with distal fibular avulsion fracture were visited for surgical treatment in Department of Sports Medicine, Peking University Third Hospital, and 60 cases were finally enrolled according to the inclusion and exclusion criteria. Intraoperative detection was regarded as the gold standard, and the diagnostic sensitivity of preoperative ankle X-ray and 3D-CT for the distal fibular avulsion fractures was statistically determined. The ossicle maximum diameter as well as the degree of its displacement were also measured. On 3D-CT, the distance from the ossicle center point to the anterior fibular tuberosity (a), the distance to the fibular tip (b), and the a/b value was used to present the ossicle displacement.@*RESULTS@#Among the 60 patients, 36 and the 52 patients were correctly detected by X-ray and 3D-CT, respectively, and the sensitivities was 60.0% and 86.7%, respectively (P=0.004). The mean diameter of the ossicle on X-ray and 3D-CT was (9.2±3.9) mm and (10.5±3.2) mm, respectively. The mean distance from the ossicle center to the anterior fibular tuberosity (a) was (17.5±3.6) mm and the mean distance to the fibular tip (b) was (17.4±4.8) mm, with mean a/b values of 1.1±0.7. The intraclass correlation coefficients (ICC) for each measurement ranged from 0.891-0.998 with a high degree of consistency.@*CONCLUSION@#Compared with X-ray, 3D-CT has higher sensitivity in diagnosing distal fibular avulsion fractures, can help clinicians evaluate ossicle's location and choose surgical methods, and is recommended to be performed in patients with suspected distal fibula avulsion fractures in clinical practice.

ABSTRACT

OBJECTIVE@#To investigate clinical effect of percutaneous reduction combined with internal fixation of calcaneal nail in treating Sanders typeⅡto Ⅲ calcaneal fractures.@*METHODS@#From July 2017 to August 2019, clinical data of 98 patients with Sanders typeⅡto Ⅲ calcaneal fractures treated were retrospectively analyzed, and divided into observation group and control group according to different surgical methods. In observation group, there were 35 males and 21 females, aged from 23 to 58 years old with an average of (34.50±7.81) years old;29 patients with Sanders typeⅡand 27 patients with Sanders type Ⅲ;30 patients on the left side and 26 patients on the right side;the time from fracture to operation ranged from 1 to 4 days with an average of (3.45±0.54) days;and treated with percutaneous reduction combined with internal fixation of calcaneal nail system. In control group, there were 25 males and 17 females, aged from 25 to 60 years old with an average of (35.27±7.64) years old;23 patients with Sanders type Ⅱ and 19 patients with Sanders type Ⅲ;24 patients on the left side and 18 patients on the right side;the time from fracture to operation ranged from 2 to 5 days with an average of (3.42±0.62) days;and treated with open reduction and internal fixation. Operation time, blood loss, hospital stay, fracture healing time, and postoperative visual analogue scale (VAS) at 1 day, preoperative and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Böhler angle, Gissane angle and calcaneus width, and postoperative complications were compared between two groups.@*RESULTS@#All patients were followed up from 13 to 18 months with an average of (15.6±2.2) months. There were significant differences in operation time, blood loss, hospital stay, fracture healing time and postoperative VAS at 1 day between two groups (P<0.05). There was statistical difference in postoperative AOFAS score at 12 months between two groups (P<0.05), and AOFAS score at 12 months after operation was higher than that before operation (P<0.05). According to AOFAS score, 21 patients got excellent result, 30 good and 5 moderate in observation group, and 10 excellent, 22 good, 7 moderate and 3 poor in control group, which had statistical difference between two groups (P<0.05). Postoperative Böhler angle, Gissane angle and calcaneus width at 6 months were better than that before operation between two groups(P<0.05). One patient in observation and 20 patients in control group occurred skin numbness after operation, and 14 patients occurred skin necrosis in control group, there were obvious difference between two groups(P<0.01).@*CONCLUSION@#Compared with open reduction and internal fixation, percutaneous reduction combined with internal fixation system in treating Sanders typeⅡto Ⅲ calcaneal fractures is feasible for fracture repair without waiting for foot deswelling, which could accurately restore normal shape and position of the fractured heel bone, completely eliminate fracture malunion, and reduce postoperative complications. Therefore, it could shorten operation time, hospital stay, fracture healing time, reduce amount of blood loss, promote postoperative recovery, and less complications, high safety, which could be used as a choice of orthopedic surgery for foot and ankle trauma.

ABSTRACT

OBJECTIVE@#To compare clinical efficacy of No-touch technique and traditional retractor in treating calcaneal fracture.@*METHODS@#Clinical data of 74 calcaneal fracture patients with closed Sanders typeⅡ to Ⅳ were retrospectively analyzed from July 2019 to June 2021. According to different treatment methods, the patients were divided into No-touch group and conventional group, 37 patinets in each group. In No-touch group, there were 25 males and 12 females, aged from 19 to 70 years old with an average of (42.64±14.16) years old;17 patients were typeⅡ, 14 patinets with type Ⅲ, 6 patients with type Ⅳ according to Sanders fracture classification;three 2.0 mm Kirschner wires were implanted into the talus body, talus neck, and cuboid bone, and the flap was turned upward to expose the operation area. In conventional group, there were 30 males and 7 females, aged from 19 to 67 years old with an average of (41.56±11.38) years old;17 patients with typeⅡ, 12 patients with type Ⅲ, 8 patients with type Ⅳ according to Sanders fracture classification;the operation was completed by exposing the operation area with traditional retractor. Operation time, postoperative incision complications, postoperaive American Orthopedic Foot and Ankle Society (AOFAS) ankle hind foot score at 6 months between two groups were compared.@*RESULTS@#Seventy-four patients were followed up, and follow-up time in No-touch group ranged from 6 to 17 months with an average of(9.57±2.72) months, while in conventional group ranged from 6 to 16 months with an averge of(9.14±2.71) months, and no difference in follow-up between two groups (P>0.05). Operation time in No-touch group (55.67±7.94) min was shorter than that in conventional group (70.16±9.41) min (P<0.05);four patients in No-touch group occurred incision complications, while 8 patients in normal group, and had statistically difference(P<0.05). Daily activities and support, maximum walking distance (block), ground walking, limited degree of flexion, extension and valgus, foot alignment and total score of AOFAS scores in No-touch group was significantly higher than that of conventional group (P<0.05). There were no significant difference in pain degree, abnormal gait and ankle hind foot stability between two groups(P>0.05). According to AOFAS score, 19 patients got excellent result, 16 good and 2 poor in No-touch group;while 9 excellent, 24 good, and 4 poor in conventional group, and no difference between two groups (P>0.05).@*CONCLUSION@#Compared with traditional retractor in treating calcaneal fracture, No-touch technology could significantly shorten operation time, reduce incidence of postopertive complications, while two methods could improve excellent and good rate of ankle joint function recovery after operation.

ABSTRACT

OBJECTIVE@#To investigate the short-term effectiveness of INBONE TM Ⅱ total ankle prosthesis arthroplasty in the treatment of moderate to severe varus-type ankle arthritis.@*METHODS@#The clinical and radiographic data of patients with moderate to severe varus-type ankle arthritis, who were admitted between May 2017 and November 2021 and treated with total ankle arthroplasty (TAA) using INBONE TM Ⅱ prosthesis, was retrospectively analyzed. A total of 58 patients (58 ankles) met the selection criteria and were included in the study. Among them, there were 24 males and 34 females, with an average age of 62.6 years (range, 41-85 years). According to the preoperative tibiotalar angle (TTA), the patients were divided into a moderate varus group (group A, TTA 5°-15°, n=34) and a severe varus group (group B, TTA>15°, n=24). There was no significant difference in gender, side, etiology, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle dorsiflexion, plantarflexion, and total range of motion, and tibial lateral surface angle (TLS) between the two groups ( P>0.05). Yet the patients in group A were younger than group B, the degrees of oesteoarthritis (Takakura stage) and ankle pain [visual analogue scale (VAS) score] were milder, and the TTA, talar tilt angle (TT), hindfoot alignment angle (HAA) were smaller while the tibial articular surface angle (TAS) was larger, showing significant differences ( P<0.05). The pre- and post-operative VAS score, AOFAS score, the occurrence of early and late complications, the radiographic parameters of the ankle (TTA, TAS, TT, HAA, TLS), ankle dorsiflexion, plantarflexion, and total range of motion were recorded and compared.@*RESULTS@#All patients were followed up 19-72 months, with an average of 38.9 months. Compared with the preoperative data, the VAS score of all patients significantly decreased ( P<0.05); the AOFAS score, ankle dorsiflexion range of motion, and total range of motion significantly increased ( P<0.05); and the TTA, TAS, TT, HAA, and TLS significantly improved at last follow-up ( P<0.05); but there was no significant difference in plantarflexion range of motion ( P>0.05). Early complications occurred in 13 patients, and only 1 patient underwent revision surgery due to a larger size of the talar component. At last follow-up, there was no significant difference in the difference of clinical parameters before and after operation between the two groups ( P>0.05); there was a significant difference in the difference of other radiographic parameters ( P<0.05) except TLS. No significant difference in the incidence of complications between the two groups was found ( P>0.05).@*CONCLUSION@#TAA using the INBONE TM Ⅱtotal ankle prosthesis is an effective treatment for moderate or severe varus-type ankle arthritis, and good clinical and radiographic results can be obtained. Correcting bony deformities and balancing soft tissue are the keys to successful surgery.

ABSTRACT

OBJECTIVE@#To establish the finite element model of varus-type ankle arthritis and to implement the finite element mechanical analysis of different correction models for tibial anterior surface angle (TAS) in supramalleolar osteotomy.@*METHODS@#A female patient with left varus-type ankle arthritis (Takakura stage Ⅱ, TAS 78°) was taken as the study object. Based on the CT data, the three-dimensional model of varus-type ankle arthritis (TAS 78°) and different TAS correction models [normal (TAS 89°), 5° valgus (TAS 94°), and 10° valgus (TAS 99°)] were created by software Mimics 21.0, Geomagic Wrap 2021, Solidworks 2017, and Workbench 17.0. The 290 N vertical downward force was applied to the upper surface of the tibia and 60 N vertical downward force to the upper surface of the fibula. Von Mises stress distribution and stress peak were calculated.@*RESULTS@#The finite element model of normal TAS was basically consistent with biomechanics of the foot. According to biomechanical analysis, the maximum stress of the varus model appeared in the medial tibiotalar joint surface and the medial part of the top tibiotalar joint surface. The stress distribution of talofibular joint surface and the lateral part of the top tibiotalar joint surface were uniform. In the normal model, the stress distributions of the talofibular joint surface and the tibiotalar joint surface were uniform, and no obvious stress concentration was observed. The maximum stress in the 5° valgus model appeared at the posterior part of the talofibular joint surface and the lateral part of the top tibiotalar joint surface. The stress distribution of medial tibiotalar joint surface was uniform. The maximum stress of the 10° valgus model appeared at the posterior part of the talofibular joint surface and the lateral part of the top tibiotalar joint surface. The stress on the medial tibiotalar joint surface increased.@*CONCLUSION@#With the increase of valgus, the stress of ankle joint gradually shift outwards, and the stress concentration tends to appear. There was no obvious obstruction of fibula with 10° TAS correction. However, when TAS correction exceeds 10° and continues to increase, the obstruction effect of fibula becomes increasingly significant.

ABSTRACT

OBJECTIVE@#To assess the effectiveness of supramalleolar osteotomy (SMOT) as a therapeutic intervention for varus-type ankle arthritis, while also examining the associated risk factors that may contribute to treatment failure.@*METHODS@#The clinical data of 82 patients (89 feet) diagnosed with varus-type ankle arthritis and treated with SMOT between January 2016 and December 2020 were retrospectively analyzed. The patient cohort consisted of 34 males with 38 feet and 48 females with 51 feet, with the mean age of 54.3 years (range, 43-72 years). The average body mass index was 24.43 kg/m 2 (range, 20.43-30.15 kg/m 2). The preoperative tibial anterior surface angle (TAS) ranged from 77.6° to 88.4°, with a mean of 84.4°. The modified Takakura stage was used to classify the severity of the condition, with 9 feet in stage Ⅱ, 41 feet in stage Ⅲa, and 39 feet in stage Ⅲb. Clinical functional assessment was conducted using the Maryland sore, visual analogue scale (VAS) score, and psychological and physical scores in Health Survey 12-item Short From (SF-12). Radiology evaluations include TAS, talar tilt (TT), tibiocrural angle (TC), tibial medial malleolars (TMM), tibiocrural distance (TCD), tibial lateral surface angle (TLS), and hindfoot alignment angle (HAA). The results of clinical failure, functional failure, and radiology failure were statistically analyzed, and the related risk factors were analyzed.@*RESULTS@#The operation time ranged from 45 to 88 minutes, with an average of 62.2 minutes. No complication such as fractures and neurovascular injuries was found during operation. There were 7 feet of poor healing of the medial incision; 9 pin tract infections occurred in 6 feet using external fixator; there were 20 cases of allograft and 3 cases of autograft with radiographic bone resorption. Except for 1 foot of severe infection treated with bone cement, the remaining 88 feet were primary healing, and the healing area was more than 80%. All patients were followed up 24-82 months, with an average of 50.2 months. Maryland score, VAS score, SF-12 psychological and physiological scores, and TAS, TC, TLS, TCD, TT, TMM, HAA, and Takakura stage were significantly improved at last follow-up ( P<0.05). Postoperative clinical failure occurred in 13 feet, functional failure in 15 feet, and radiology failure in 23 feet. Univariate analysis showed that obesity, TT>10°, and Takakura stage Ⅲb were risk factors for clinical failure, HAA≥15° and Takakura stage Ⅲb were risk factors for functional failure, and TT>10° was risk factor for radiographic failure ( P<0.05). Further logistic regression analysis showed that TT>10°, HAA≥15°, and TT>10° were risk factors for clinical failure, functional failure, and radiographic failure, respectively ( P<0.05).@*CONCLUSION@#SMOT is effective in the mid- and long-term in the treatment of varus-type ankle arthritis, but it should be used with caution in patients with obesity, severe hindfoot varus, severe talus tilt, and preoperative Takakura stage Ⅲb.

ABSTRACT

OBJECTIVE@#To investigate the short-term effectiveness of calcaneal lateral displacement osteotomy with lateral ligament repair in the treatment of Takakura stage Ⅱ varus-type ankle arthritis.@*METHODS@#A retrospective analysis was performed on the clinical data of 13 patients with Takakura stage Ⅱ varus-type ankle arthritis treated with calcaneal lateral displacement osteotomy with lateral ligament repair between January 2016 and December 2020. There were 6 males and 7 females aged 31-65 years, with an average age of 53.6 years. The preoperative tibial-ankle surface angle (TASA) was (88.13±1.01)°, medial distal tibial angle (MDTA) was (86.36±1.49)°, tibial talar surface angle (TTSA) was (6.03±1.63)°, talar tilting angle (TTA) was (81.95±2.15)°, and tibiocalcaneal axis angle (TCAA) was (-5.74±6.81)°. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 56.3±7.1 and the pain visual analogue scale (VAS) score was 3.7±0.5. AOFAS scores, VAS scores, TTSA, TTA, and TCAA were compared between pre- and post-operatively.@*RESULTS@#All 13 patients were followed up 14-41 months, with an average of 28.7 months. The osteotomies healed in all patients. The last follow-up revealed TTA, TTSA, and TCAA to be (88.27±1.19)°, (-0.13±1.37)°, and (2.09±5.10)° respectively, the AOFAS score was 84.3±4.2 and the VAS score was 0.7±0.5, all showing significant improvement when compared to preoperative values ( P<0.05).@*CONCLUSION@#For patients with Takakura stage Ⅱ varus-type ankle arthritis, calcaneal lateral displacement osteotomy with lateral ligament repair can correct the lower limb force line, regain ankle stability, and achieving good short-term effectiveness.

ABSTRACT

OBJECTIVE@#To evaluate the early effectiveness of a new minimally invasive plate in the treatment of varus-type ankle arthritis.@*METHODS@#A clinical data of 15 patients with varus-type ankle arthritis who met the selection criteria between March 2021 and October 2021 were retrospectively analyzed. All the patients were treated with medial open-wedge supramalleolar osteotomy and fibular osteotomy. The osteotomies were fixed with the new minimally invasive plate. There were 7 males and 8 females with an average age of 49.8 years (range, 16-71 years). The causes of ankle arthritis included post-fracture deformity in 1 case, sprain in 8 cases, and acquired clubfoot in 1 case; and 5 cases were without obvious factors. The disease duration ranged from 1 to 12 years, with an average of 4.1 years. Comparisons were made between pre-operation and the last follow-up in the Takakura staging, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, foot function index (FFI), visual analogue scale (VAS) score, tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).@*RESULTS@#All incisions healed by first intention. All patients were followed up 7-18 months (mean, 12.8 months). At last follow-up, the AOFAS ankle-hindfoot score, FFI, VAS score, and Takakura staging significantly improved when compared with the preoperative ones ( P<0.05). X-ray films showed that the osteotomy healed at 3 months after operation. At last follow-up, TAS significantly increased and TT decreased when compared with the preoperative ones ( P<0.05), and the difference in TLS between pre- and post-operation was not significant ( P>0.05). Complications included 1 case of intraoperative screw breakage and 2 cases of nerve injury of the affected foot. None of the patients complained of significant discomfort at the plate placement during follow-up, and no loosening of the internal fixator occurred. Eleven patients were very satisfied with the effeectiveness, while 4 were relatively satisfied.@*CONCLUSION@#The new minimally invasive plate for the varus-type ankle arthritis has good early effectiveness in relieving ankle pain, correcting deformity, improving limb alignment and ankle function, and reducing the incidence of postoperative incisional complications.

ABSTRACT

Ankle arthritis affects approximately 1% of the adult population worldwide and represents a serious global disease burden. However, compared with hip arthritis and knee arthritis, the clinical understanding and treatment of ankle arthritis are still in their infancy. For end-stage ankle arthritis, ankle arthrodesis was considered as the "gold standard" in the past. However, ankle arthrodesis will result in loss of joint mobility, altered gait, limited daily activities, and accelerated degeneration of adjacent joints. Therefore, how to preserve the range of motion of the ankle joint while relieving pain is the key to the treatment of ankle arthritis. Currently, the surgical treatment of ankle arthritis includes arthroscopic debridement, periarticular osteotomies, osteochondral transplantation, ankle distraction arthroplasty, ankle arthrodesis, and total ankle arthroplasty. The choice of treatment should be individualized and based on various factors such as the patient's symptoms, signs, imaging performance, complaints, and financial situation. However, there are no guidelines that give clear treatment recommendations. Therefore, it is necessary to conduct extensive and in-depth discussions on the diagnosis and treatment of ankle arthritis.

ABSTRACT

Objective: To study the protective effect of parachute ankle brace on ankle joint during simulated parachuting landing. Methods: In August 2021, 30 male paratroopers were selected as the test subjects by simple random sampling method. They jumped from the 1.5 m and 2.0 m height platforms respectively with and without parachute ankle brace, and landed on the sandy ground in a semi-squat parachute landing position. The experiment was divided into 1.5 m experimental group and control group and 2.0 m experimental group and control group. Angle sensor and surface electromyograph were used to measure and analyze the coronal tilt range of the ankle joint and the percentage of maximal voluntary contraction (MVE%) of the muscles around the ankle joint, respectively, to evaluate the protective effect of the parachute ankle brace. Results: At the same height, the tilt range of coronal plane of ankle in experimental group was significantly reduced compared with control group, and the difference was statistically significant (P<0.05). Under the same protection state, the tilt range of the coronal plane of the ankle in the 1.5 m group was significantly reduced compared with that in the 2.0 m group, and the difference was statistically significant (P<0.05). The coronal plane inclination range of the ankle in 2 m experimental group was significantly lower than that in 1.5 m control group, and the difference was statistically significant (P<0.05). Compared with 1.5 m control group, MVE% of right tibialis anterior muscle and bilateral lateral gastrocnemius decreased in 1.5 m experimental group, while MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle and right lateral gastrocnemius decreased in 2.0 m experimental group, while the MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). The MVE% of bilateral tibialis anterior muscle, bilateral lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m experimental group decreased compared with 2.0 m experimental group, and the differences were statistically significant (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle, right lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m control group decreased, and the differences were statistically significant (P<0.05) . Conclusion: Wearing parachute ankle brace can effectively limit the coronal plane inclination range of ankle joint, improve the stability of ankle joint and reduce the load on the muscles around ankle joint by landing. Reducing the height of the jumping platform can reduce the coronal plane incline range of the ankle and the muscle load around the ankle during landing.

ABSTRACT

PURPOSE@#To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants.@*METHODS@#A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05.@*RESULTS@#There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL.@*CONCLUSION@#The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

ABSTRACT

Arthroscopic treatment of ankle impingement syndrome (AIS) is a minimally invasive surgical procedure used to address symptoms caused by impingement in the ankle joint. This syndrome occurs when there is abnormal contact between certain bones or soft tissues in the ankle, leading to pain, swelling, or limited range of motion. Traditionally, open surgery was the standard approach for treating AIS. However, with advancements in technology and surgical techniques, arthroscopic treatment has become a preferred method for many patients and surgeons. With improved visualization and precise treatment of the arthroscopy, patients can experience reduced pain and improved functionality, allowing them to return to their daily activities sooner. In this paper, we reviewed the application and clinical efficacy the of arthroscopic approach for treating AIS, hoping to provide a reference for its future promotion.
