PURPOSE: To date, there is a paucity of literature on syndesmotic reconstruction techniques that restore both anatomic stability and physiologic syndesmotic biomechanics. In this cadaveric study, (1) a novel syndesmotic reconstruction surgical technique using autogenous peroneus brevis tendon was described and (2) the biomechanical properties of the reconstruction was investigated. METHODS: Ten fresh-frozen lower extremities were used in this study. Reconstruction of the anterior and posterior, as well as the interosseous tibiofibular ligaments was performed with a halved peroneus brevis tendon...

Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

BACKGROUND/PURPOSE: There have been no studies assessing the optimal biomechanical tension of suture button constructs. The purpose of this study was to assess optimal tensioning of suture button fixation and its ability to maintain reduction under loaded conditions using a stress computed tomography (CT) model. METHODS: Ten cadaveric lower limbs disarticulated at the knee were used. The limbs were placed in a modified ankle load frame that allowed for the application of sustained torsional axial or combined torsional/axial loads...

BACKGROUND: Osteoid osteoma (OO) is a common benign bone tumour that is rarely found in the talus. Its nidus is difficult to detect on early imaging. The atypical symptoms of OO and the presence of concurrent trauma or sports injuries may lead to misdiagnosis and delayed treatment. We herein analyse a case of misdiagnosis of OO of the talus and discuss how to improve the early diagnosis of this rare lesion, thereby permitting rapid treatment. CASE PRESENTATION: A 23-year-old man with a history of left ankle sprains and chronic pain was diagnosed with another ankle sprain and managed conservatively based on normal X-ray findings...

PURPOSE OF REVIEW: Ankle sprains, which account for 40% of sports injuries in the USA, can lead to chronic ankle instability. Chronic ankle instability can be classified as functional, mechanical, or a combination of both and is diagnosed using a combination of a physical exam, an MRI, and stress radiographs. This review focuses on different approaches to treatment, including non-operative and operative techniques, of chronic ankle instability, including reviewing traditional procedures as well as more novel and newer techniques...

BACKGROUND: Coronal deformity correction with total knee arthroplasty (TKA) is an important feature in the treatment of osteoarthritis (OA). The hypothesis of this study was that bone morphology would be different in varus and valgus deformity, both before osteoarthritis development as well as during and after the disease process of OA. MATERIALS AND METHODS: Retrospective study with measurements on preoperative and postoperative full leg standing radiographs of 96 patients who underwent TKA...

We compared four repair techniques for impaired ankle ligament deltoideum, namely Wiltberger, Deland, Kitaoka and Hintermann using a 3-dimensional finite element. We built an ankle ligament deltoideum model, including six pieces of bone structures, gristles and main ligaments around the ankle. After testing the model, we built an impaired ligament deltoideum model plus four reconstruction models. Subsequently, different levels of force on ankles with different flexion were imposed and ankle biomechanics were compared...

BACKGROUND: It is unclear whether simultaneous surgery for posterior ankle impingement syndrome (PAIS) and concomitant ankle disorders, such as anterior ankle impingement syndrome (AAIS), lateral ankle instability (LAI), and osteochondral lesion of the talus (OLT), allows for early return to athletic activity. METHODS: Ninety-seven patients who engaged in athletic activity (mean age 27 [range 18-43] years) and were treated by a hindfoot endoscopic approach for PAIS alone or simultaneously for PAIS and concomitant ankle disorders were included in this study...

In this series, we aimed to describe the sonographic findings of chondral avulsion fractures that develop concomitant with lateral ankle ligament injury in children. We performed stress sonography during a manual anterior drawer stress procedure of the ankle in 9 skeletally immature patients who had recently had a lateral ankle sprain. Echo videos were obtained through the course of treatment, and all videos were reviewed. We elucidated the common features of chondral avulsion fractures of the lateral ankle ligaments in the children...

BACKGROUND: In patients who develop chronic ankle instability, clinicians often obtain magnetic resonance imaging (MRI) as part of the evaluation prior to operative referral. The purpose of this study was to analyze the diagnostic efficacy of MRI in the diagnosis of chronic lateral ankle instability. Our hypothesis was that magnetic resonance imaging would not be a specific diagnostic tool in the evaluation of chronic lateral ankle instability. MATERIALS AND METHODS: A retrospective chart review of 187 consecutive patients (190 ankles) was performed...

BACKGROUND: Extensive medial soft tissue release may be necessary to correct severe varus deformity during total knee arthroplasty (TKA). However, this procedure may result in instability. Here, we describe a novel soft tissue balancing technique, which can minimize medial release in severe varus deformity during TKA. METHODS: Fifty knees (40 patients) with hip-knee-ankle angle of more than 20° of varus were corrected using this technique (group 1). After achieving flexion gap balancing by needle puncturing and spreading of the superficial medial collateral ligament, extension gap balancing was obtained by gradual extension with the trial components in place...

Chronic ankle instability causes intra-articular lesions, which may lead to secondary degenerative changes. The aim of this study was to evaluate the usefulness of the ankle arthroscopy for the evaluation and treatment of intra-articular pathologies associated with chronic ankle instability. Between January 2013 and March 2016, 25 anterior ankle arthroscopies with modi ed anatomic Broström-Duquennoy-Tourne lateral ankle ligaments reconstructions were performed. In arthroscopy all patients (100%) had some intra-articular pathologies: 75% synovitis or so tissue scarring, 19% - deep chondral defect, 56% - superficial chondral lesion, 52% - osteophytes, 24% - bony or avulsion fragments, 20% - loose bodies...

Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event...

Chul Hyun Park, Woo-Chun Lee
BACKGROUND: The anterior half of the peroneus longus tendon (AHPLT) has been reported to be an effective autograft for ligament reconstruction with respect to strength and safety. However, there is little information regarding donor site morbidity after harvesting the AHPLT. Furthermore, to the best of our knowledge, there has not been a study on the isokinetic evaluation of ankle plantar flexion and eversion after AHPLT harvesting. PURPOSE: To evaluate the clinical and radiographic results after lateral ankle ligament reconstruction using the AHPLT...

Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination-external rotation injuries. Deltoid ligament injuries have a significant impact on lateral ankle instability but can be overlooked in patients with lateral ligament injuries. Posterior tibial tendon dysfunction is usually associated with spring ligament or flexor retinaculum injury. Tarsal tunnel syndrome, accessory flexor muscles, and subtalar coalition should be considered as well as ligament and tendon tears in differential diagnosis of chronic medial ankle pain...

Capsule/ligament lesions of the lateral compartment of the ankle lead to lateral laxity, which is a prime contributor to chronic ankle instability. Lateral ligament reconstruction stabilizes the joint. Exhaustive preoperative clinical and paraclinical work-up is essential. The present article classifies, presents and criticizes the main techniques in terms of long-term stabilization and reduction of osteoarthritis risk. Anatomic ligament repair with reinforcement (mainly extensor retinaculum) or anatomic ligament reconstruction are the two recommended options...

OBJECTIVE: Idiopathic flexible pes planus (IFPP) is a common foot problem in adolescents and young adults. Hypothesis for the present study was that combination of procedures for IFPP can achieve results in adolescents and young adults that are as good as those seen in adult-acquired pes planovalgus (AAPP) treatment in adults. METHODS: A total of 21 feet of 18 patients (10 boys, 8 girls) with mean age of 15.6 years underwent surgical reconstruction for flatfoot deformity...

CONTEXT: While the incidence and re-injury rates of lateral ankle sprain (LAS) continue to persist at high rates across many sporting activities, further exploration of assessment and treatment beyond the traditional ligamentous and strength/proprioceptive model is warranted. Further, assessing and treating both arthrokinematic and osteokinematic changes associated with LAS can provide insight into a more diverse approach to treating ankle pathology. OBJECTIVE: To examine the clinical use of the Mulligan Concept MWM while treating patients diagnosed with an acute grade I or II LAS through authentic patient care...

CONTEXT: The mechanisms that contribute to the development of chronic ankle instability are not understood. Investigators have developed a hypothetical model in which neuromuscular alterations that stem from damaged ankle ligaments are thought to affect periarticular and proximal muscle activity. However, the retrospective nature of these studies does not allow a causal link to be established. OBJECTIVE: To assess temporal alterations in the activity of 2 periarticular muscles of the rat ankle and 2 proximal muscles of the rat hind limb after an ankle sprain...
