BACKGROUND: Infection is a serious complication of primary total ankle arthroplasty (TAA) and can lead to implant failure and revision surgery. Various demographic, comorbidity, and surgical factors have been associated with an increased risk of infection. However, the evidence base remains limited, and further research is needed regarding infection in TAA. This study aims to analyze risk factors of infection and explore outcomes following infected TAA. METHODS: A retrospective cohort study was conducted using data from a single institution from 2002 to 2022...

BACKGROUND: Hallux interphalangeal joint arthrodesis (HIPJA) is indicated for a variety of pathologies. Despite high nonunion rates, techniques remain unchanged. The aim of this study is to examine nonunion and complication rates and describe risk factors for treatment failure. METHODS: A query of an institutional database was performed to identify all patients undergoing HIPJA procedure over a 10-year period. Records were reviewed to the procedure, evaluate patient factors, indications, and radiographic/clinical arthrodesis...

BACKGROUND: There is growing evidence that total ankle arthroplasty (TAA) can safely be performed as an outpatient procedure, with the benefit of decreased health care expenses and improved patient satisfaction. The purpose of our study was to compare readmissions, arthroplasty failures, infections, and annual trends between outpatient and inpatient TAA using a large publicly available for-fee database. METHODS: The PearlDiver Database was queried to identify outpatient and inpatient TAA-associated claims for several payer types from January 2010 to October 2021...

BACKGROUND: Insertional Achilles tendinopathy (IAT) is a common condition causing pain and dysfunction. Patients with diabetes, hyperlipidemia, hypothyroidism, and obesity are at increased risk of developing IAT. These comorbidities also carry an increased risk of wound healing complications following surgery. Therefore, there is a need for alternative management strategies for this high-risk patient population. This study investigated the potential role of isolated GR in patients with chronic IAT...

BACKGROUND: To propose and validate a modified noninvasive method for the diagnosis of chronic syndesmotic injuries. METHODS: This study included 16 patients with chronic ankle instability. Herein, we propose the Modified Stabilization Test, a new measurement for use in the diagnosis of chronic syndesmotic injury, as determined by wearing a 60-kPa pneumatic brace. The test combines the center of pressure and sensory organization test to measure postural control...

BACKGROUND: The use of weightbearing images to diagnose foot and ankle injuries continues to offer hope for improved insight into pathologies, but weightbearing CT imaging has been limited by availability. The ability to apply force to the lower limb in a horizontal bore CT system may offer an adaptation to currently available imaging systems that provides access to weightbearing images without the acquisition of additional expensive imaging space or equipment. METHODS: In order to determine whether a horizontal CT system could produce the same results as a standing CT, 3 images of one foot from 10 subjects was obtained and standard measures were calculated...

BACKGROUND: Ankle arthritis that develops after fracture accounts for a significant portion of ankle arthritis necessitating total ankle arthroplasty (TAA). It remains unknown whether TAA in postfracture patients produces equivalent outcomes to those without fracture history. The purpose of this study was to evaluate the medium-term outcomes of TAA in postfracture ankle arthritis compared to those without fracture history. METHODS: This study reviewed 178 ankles from 171 consecutive patients who underwent TAA in our institution between 2007 and 2017 and completed a minimum 5-year follow-up...

BACKGROUND: Placement of clamp forceps along the transsyndesmotic (TS) axis reduces the risk of iatrogenic syndesmotic malreduction during ankle fracture surgery with tibiofibular diastasis. This study aimed to measure the difference between the TS axis and the axis determined by an intraoperative fluoroscopic technique using the center-center (CC) method. We also compared the values obtained when the CC method was performed at different heights from the tibial plafond. METHODS: We evaluated the computed tomography scans of 150 patients with normal syndesmosis...

BACKGROUND: First metatarsophalangeal (MTP) arthrodesis is a common surgical intervention for addressing MTP pain and deformity. Despite great interest on the topic of return to sport (RTS) after first MTP arthrodesis in the literature, no systematic review exists on this topic. The purpose of this systematic review is to investigate RTS after first MTP arthrodesis. METHODS: This study is a systematic review using PubMed, Web of Science, CINAHL, and MEDLINE from database inception until May 10, 2023...

BACKGROUND: Foot and ankle soft tissue sarcomas (STSs) are rare neoplasms associated with a high risk of local recurrence and metastasis. Although amputation is often performed, its impact on prognosis remains unknown. The aims of our systematic review were identifying risk factors for (1) disease-specific death, (2) local recurrence, (3) metastasis, and assessing (4) whether the type of surgery (amputation or limb-salvage) affected disease-specific survival. METHODS: This systematic review was conducted following PRISMA guidelines...

BACKGROUND: Subluxation at the subtalar joint is one of the major radiographic features that characterize progressive collapsing foot deformity (PCFD). Although it is recognized that the cervical ligament plays an important function in maintaining the subtalar joint's stability, its role and involvement in PCFD is largely unknown. The purpose of this study was to assess the prevalence of cervical ligament insufficiency in patients with PCFD and to establish if the degree of its pathology changes with increasing axial plane deformity...

BACKGROUND: Low-energy stage II Lisfranc injuries are rare, and treatment can be operative or nonoperative based on a surgeon's assessment of midfoot stability. No previously published patient-reported outcome measures (PROMs) data for Lisfranc injuries isolates purely ligamentous stage II injuries. The purpose of this study was to analyze PROMs for patients who underwent operative management of stage II Lisfranc injuries. METHODS: Thirty-nine patients (39 feet) with confirmed Nunley-Vertullo stage II Lisfranc injuries between May 2012 and February 2022 were identified through a retrospective chart review...

BACKGROUND: Total ankle arthroplasty (TAA) is a preferred surgical option for end-stage ankle osteoarthritis; however, it is a demanding procedure with a higher historical rate of revision compared with ankle fusion. Patient-specific instrumentation (PSI) has been introduced to optimize prosthesis alignment and theoretically overall improve TAA outcomes. The goal of this study is to report on the experience and surgical outcomes of one implant with specific evaluation of the accuracy and reproducibility of the system with respect to prosthesis alignment and prediction of implant size...

BACKGROUND: Persistent posttraumatic/postsurgery ankle edema (PPAE) is edema that persists from 2 weeks to 3 months after injury or surgery. PPAE has negative effects on the healing process and quality of life. This study aimed to evaluate the efficacy of a phytochemical product containing diosmin, coumarin, and arbutin (Linfadren) in addition to the conventional treatment, in patients with PPAE. METHODS: Between October 2018 and February 2020, 60 outpatients with PPAE (42 with ankle fractures and 18 with ankle sprains) were enrolled and randomized (1:1 ratio) to receive either 6-week conventional treatment plus Linfadren (study group) or conventional treatment alone (control group)...

BACKGROUND: There is uncertainty regarding the optimal surgical intervention for diabetic foot osteomyelitis (DFO). Conservative surgery-amputation-free resection of infected bone and soft tissues-is gaining traction as an alternative to minor amputation. Our primary objective was to explore the comparative effectiveness of conservative surgery and minor amputations in clinical failure risk 1 year after index intervention. We also aimed to explore microbiological recurrence at 1 year, and revision surgery risk over a 10-year study period...

BACKGROUND: Chronic exertional compartment syndrome involving the lower leg lateral compartment (lat-CECS) seldom occurs isolated but is usually combined with CECS of the anterior (ant-CECS) or deep posterior compartment (dp-CECS). Patient characteristics in lat-CECS and outcome after surgery are largely unknown. The aim of this prospective case series was to describe patient characteristics and symptoms and to report on outcome following a fasciotomy. METHODS: All patients diagnosed with lat-CECS based on exertional lateral lower leg symptoms and elevated intracompartmental pressure (ICP) measurements according to the Pedowitz criteria (ICP ≥ 15 mm Hg at rest, and/or ≥30 mm Hg after 1 minute, and/or ≥20 mm Hg 5 minutes after exercise) were eligible for this study...

BACKGROUND: Peritalar subluxation (PTS) is part of progressive collapsing foot deformity (PCFD). This study aimed to evaluate initial deformity correction and PTS optimization in PCFD patients with flexible hindfoot deformity undergoing hindfoot joint-sparing surgical procedures and its relationship with improvements in patient-reported outcome measures (PROMs) at latest follow-up. We hypothesized that significant deformity/PTS correction would be observed postoperatively, positively correlating with improved PROMs...

BACKGROUND: Ankle fractures are common orthopaedic injuries that may be indicated for open reduction internal fixation (ORIF). Although the negative impact of tobacco use on perioperative outcomes of ankle fracture ORIF has been described, the potential impact of cannabis use on related outcomes is not as well established. METHODS: Retrospective database study of adult patients undergoing ankle ORIF for closed, isolated, ankle fractures from the 2010-2021 Q1 PearlDiver M151 data set...

BACKGROUND: We evaluated whether the quality of syndesmotic reduction affects the short-term clinical outcomes of flexible fixation in patients with a rotational ankle fracture. METHODS: This study included 59 patients (32 men and 27 women) who underwent syndesmotic flexible fixation. The degree of syndesmotic reduction was evaluated on computed tomography (CT) images acquired within 3 days after surgery. We measured the divergence between anterior and posterior incisura at 1 cm above the distal tibial articular joint, then evaluated the degree of fibular rotation relative to the tibia...
