BACKGROUND: Ankle arthritis is a highly limiting pathology that causes pain and functional limitation with subsequent deterioration of quality of life. With recent advances in surgical instrumentation and techniques, prosthetic replacement of the ankle has proven to be a valid alternative to arthrodesis with comparable outcomes. The purpose of this study was to evaluate clinical and radiological findings in a transfibular total ankle replacement with follow-up of at least 2 years. METHODS: This prospective study included 89 patients who underwent transfibular total ankle arthroplasty from May 2013 to February 2016...

BACKGROUND: The current work sought to quantify pronation of the first metatarsal relative to the second metatarsal and of the proximal phalanx of the great toe relative to the first metatarsal. METHODS: Three-dimensional models were reconstructed from weightbearing computed tomography (CT) images (10 hallux valgus, 10 normal). The orientations of bones related to hallux valgus (HV) (ie, the phalanx, first and second metatarsals) were determined from coordinate systems established by selecting landmarks...

BACKGROUND: The incidence rate of venous thrombotic events (VTEs) following foot and ankle surgery is low. Currently, there is no consensus regarding postoperative prophylaxis or evidence to support risk stratification. METHODS: A 2-part study assessing the incidence and factors for the development of VTE was conducted: (1) a retrospective observational cohort study of 22 486 adults to calculate the overall incidence following foot and/or ankle surgery from January 2008 to May 2011 and (2) a retrospective matched case-control study to identify risk factors for development of VTE postsurgery...

BACKGROUND: Malunion of a medial impacted ankle fracture may cause varus ankle deformity. This retrospective study examined the use of supramalleolar osteotomy combined with an intra-articular osteotomy in patients with malunited medial impacted ankle fractures. METHODS: Twenty-four patients with malunited medial impacted ankle fracture were treated between January 2011 and December 2014. Using Weber's classification, 10 had type A fractures and 14 had type B, and with the AO classification, 20 had 44A2 and 4 had 44B3...

BACKGROUND: The knee scooter is a commonly used mobility device in the setting of unilateral below-knee immobilization. The bent-knee posture has been shown to decrease venous flow in a seated position, but the knee scooter differs as the patient is weightbearing through the affected extremity. Our goal was to investigate the effects of knee scooter positioning on popliteal venous flow. METHODS: Duplex ultrasonography was performed to obtain venous diameter and flow velocity of the popliteal vein on healthy subjects over the age of 18 without immobilization...

BACKGROUND: A number of new 2-component total ankle arthroplasty systems that emphasize minimal bone resection have been introduced for which few clinical outcomes reports are available. Our aim was to identify the rate of early revision among patients receiving the 2-component INFINITY prosthesis. METHODS: Patients from 2 prospectively collected databases at the authors' institution were screened for inclusion in the present study. All patients who underwent a primary total ankle arthroplasty (TAA) with the INFINITY prosthesis and who were at least 1 year postoperative were included...

BACKGROUND: End-stage tarsometatarsal (TMT) arthritis is commonly treated with arthrodesis of involved joints. Fixation hardware can consist of varying combinations of screws, plates, and staples with or without supplemental bone graft. There are limited data to demonstrate either superiority of a given fixation method or the impact of bone graft on fusion rates. The purpose of this study, therefore, was to determine whether nonunion rates after TMT arthrodesis were influenced by either the use of screw vs plate fixation or the addition of bone graft vs no bone graft...

BACKGROUND: Preoperative mental health status as a predictor of operative outcome has been a growing area of interest. In this paper, the correlation between preoperative mental health status and postoperative functional outcome following scarf osteotomy for hallux valgus correction was explored. METHODS: Parameters were tabulated preoperatively and postoperatively at a minimum of 1-year follow-up. They included the Short Form 36 (SF-36), American Orthopaedic Foot & Ankle Society (AOFAS) forefoot score, hallux valgus angle (HVA), and intermetatarsal angle (IMA) measurements and the visual analog score (VAS) to quantify pain...

Failure to anatomically reduce and stabilize the fractured distal fibula can result in malunion of the fibula and malreduction of the ankle mortise. Fibular malunion results in altered ankle joint biomechanics which often leads to the development of pain, stiffness, and premature joint degeneration. Fortunately, many fibular malunions can be successfully salvaged using osteotomy techniques to restore anatomic fibular length and rotation. Different osteotomy techniques are indicated depending on the location and characteristics of the malunion...

BACKGROUND: Studies examining the clinical outcomes of revision total ankle arthroplasty (TAA) are sparse. Revision TAA surgery has become more common with availability of revision implants and refinement of bone-conserving primary implants. In this study, patient-reported results and clinical outcomes were analyzed for a cohort of patients who underwent both primary and revision TAA at a single high-volume institution. METHODS: We retrospectively reviewed prospectively collected data on 29 patients with failed primary total ankle arthroplasty...

BACKGROUND: Arthroscopic microfracture can effectively treat osteochondral lesions of the talus (OLTs). However, very few studies have reported on symptomatic improvement duration and time when symptomatic improvement ceases. This study aimed to investigate the clinical outcome changes after arthroscopic microfracture in patients with OLT. METHODS: Among patients who underwent arthroscopic microfracture for OLT, 70 patients were available for follow-up for more than 3 years...

BACKGROUND: Evaluation of patients undergoing hallux valgus surgery has historically emphasized radiographic angles and relationships. However, patient-reported outcomes are increasingly important as health care systems trend towards a "value-based" delivery approach. METHODS: We conducted a retrospective analysis of pre-existing data in our practice to examine whether patient-reported outcomes after bunion surgery, determined via Foot and Ankle Outcome Scores (FAOS), correlated with radiographic parameters commonly measured in hallux valgus deformity...

BACKGROUND: Controversies remain regarding the preferred treatment strategy for talus fractures. The primary goal of this study was to evaluate the long-term outcome after operative management of talus fractures. Secondarily, we identified those factors that affected the outcome and defined strategies to improve the outcome. METHODS: This is a retrospective outcome study of 84 patients with an average follow-up time of 9.1 years. We assessed the functional results, return to daily activities, and general health status using the Foot Function Index-5pt, a numeric rating scale for pain, and the Short Form-36 Health Survey...

BACKGROUND: Talonavicular (TN) fusion using screws dorsomedially and dorsolaterally can cause neurovascular injury. The purpose of our cadaveric study was to evaluate the safety of percutaneous screw insertion in relation to dorsal neurovascular structures. METHODS: Ten fresh-frozen cadaver legs were used for this study. Percutaneous cannulated screws were inserted to perform isolated TN arthrodesis. The screws were inserted at 3 consistent sites: a "medial screw" at the dorsomedial navicular where it intersected at the medial plane of the first cuneiform, a "central screw" at the edge of the dorsal navicular between the medial and intermediate cuneiforms, and a "lateral screw" at the edge of the dorsal navicular between the intermediate and lateral cuneiforms...

BACKGROUND: There is limited information regarding the outcomes of operative treatment for ankle instability with coexisting arthritic changes in the medial gutter. This study was performed to evaluate the intermediate-term clinical and radiological outcomes following a modified Broström procedure and arthroscopic debridement in middle-aged patients with combined medial gutter osteoarthritis and chronic ankle instability. METHODS: Twenty-two patients with medial gutter osteoarthritis related to chronic lateral ankle instability were followed for more than 3 years after operative treatment...

BACKGROUND: Plantar heel pain is a common disorder that can lead to substantial pain and disability. Gastrocnemius recession has been described as an operative treatment option, but there is a lack of prospective clinical and biomechanical outcome data. The aim of this study was to evaluate the clinical and biomechanical outcomes of gastrocnemius recession and stretching compared with a stretching exercise protocol for patients with plantar heel pain lasting more than 12 months. METHODS: Forty patients with plantar heel pain lasting more than 1 year were randomized to a home stretching exercise program only or to surgery consisting of a proximal medial gastrocnemius recession in addition to stretching exercises...

BACKGROUND: Diagnosis and operative treatment of syndesmotic ankle injuries remain challenging due to the limitations of 2-dimensional imaging. The aim of this study was therefore to develop a reproducible method to quantify the displacement of a syndesmotic lesion based on 3-dimensional computed imaging techniques. METHODS: Eighteen patients with a unilateral syndesmotic lesion were included. Bilateral imaging was performed with weightbearing cone-beam computed tomography (CT) in case of a high ankle sprain (n = 12) and by nonweightbearing CT in case of a fracture-associated syndesmotic lesion (n = 6)...

BACKGROUND: Overprescription of narcotic pain medication is a major culprit in the present opioid epidemic plaguing the United States. The current literature on lower extremity opioid usage has limitations and would benefit from additional study. The purpose of our study was to prospectively assess opioid consumption patterns following outpatient orthopedic foot and ankle procedures. METHODS: Patients undergoing outpatient orthopedic foot and ankle procedures who met inclusion criteria had the following prospective information collected: patient demographics, preoperative health history, patient-reported outcomes, anesthesia type, procedure type, opioid prescription and consumption details...
