Femoral Head Allografts for Talar Body Defects
J. Chris Coetzee, MD, Bryan D. Den Hartog, MD, Rebecca Stone McGaver, MS, ATC, Kayla J. Seiffert, BA, M. Russell Giveans, PhD

First Published February 5, 2021; pp. 815–823
Large structural bone deficits after a failed ankle arthroplasty or avascular necrosis (AVN) of the talus present a complex reconstruction challenge. The aim of this study was to report the results of patients undergoing an ankle arthrodesis or tibiotalocalcaneal fusion using a femoral head allograft (FHA).

The outcomes of revision subtalar arthrodesis have received relatively little focus in research compared with primary subtalar arthrodesis outcomes. This study aimed to assess the midterm clinical and radiologic results of subtalar joint revision arthrodesis and to analyze the risk factors that might influence the outcome of this procedure.
Long-term Outcomes of Microfracture for Treatment of Osteochondral Lesions of the Talus
Daniel Corr, BS, Jared Raikin, BS, Joseph O’Neil, MD, Steven Raikin, MD
doi : 10.1177/1071100721995427
First Published March 10, 2021; pp. 833–840
Microfracture is the most common reparative surgery for osteochondral lesions of the talus (OLTs). While shown to be effective in short- to midterm outcomes, the fibrocartilage that microfracture produces is both biomechanically and biologically inferior to that of native hyaline cartilage and is susceptible to possible deterioration over time following repair. With orthobiologics being proposed to augment repair, there exists a clear gap in the study of long-term clinical outcomes of microfracture to determine if this added expense is necessary.
Comparison of Functional and Radiographic Outcomes of Talar Osteochondral Lesions Repaired With Micronized Allogenic Cartilage Extracellular Matrix and Bone Marrow Aspirate Concentrate vs Microfracture

Microfracture (MF) has been used historically to treat osteochondral lesions of the talus (OLTs), with favorable outcomes reported in approximately 80% to 85% of cases. However, MF repairs have been shown to degrade over time at long-term follow-up, suggesting that further study into optimal OLT treatment is warranted. The use of adjuvant extracellular matrix with bone marrow aspirate concentrate (ECM-BMAC) has not been extensively evaluated in the literature. We present a comparison of patient-reported and radiographic outcomes following ECM-BMAC repair vs traditional MF.

Several benefits are published supporting patient-specific instrumentation (PSI) in total ankle arthroplasty (TAA). This study seeks to determine if TAA with PSI yields different radiographic outcomes vs standard instrumentation (SI).
Influence of Complications and Revision Surgery on Fulfillment of Expectations in Foot and Ankle Surgery
Bopha Chrea, MD, Jonathan Day, MS, Jensen Henry, MD, Elizabeth Cody, MD, HSS Orthopaedic Foot and Ankle Surgery Group, Scott Ellis, MD
doi : 10.1177/1071100720985231
First Published February 1, 2021; pp. 859–866
Fulfillment of patients’ expectations following foot and ankle surgery has been previously studied, and shown to be an effective modality in assessing patient-reported outcomes (PROs). Although this assessment has been shown to correlate well with patient satisfaction and other validated PROs, the impact of postoperative complications on fulfillment of expectations is unknown. The aim of this study is to therefore investigate the impact of postoperative complications on fulfillment of patients’ expectations.
Total Ankle Arthroplasty With Valgus Deformity
Camilo Piga, MD, Camilla Maccario, MD, Riccardo D’Ambrosi, MD, Fausto Romano, PhD, Federico Giuseppe Usuelli, MD
doi : 10.1177/1071100720985281
First Published February 1, 2021; pp. 867–876
A substantial coronal plane deformity is common in the context of end-stage ankle osteoarthritis. Recent literature shows a trend toward extending the indication of total ankle arthroplasty in increasingly severe coronal deformities, showing promising results when correct alignment is achieved. Nevertheless, the results of lateral transfibular total ankle replacement (LTTAR) in valgus has not been extensively studied. We aimed to evaluate if the outcomes of LTTAR in ankles with valgus deformity were similar to those with no major deformity at short-term follow-up.
Anatomic Repair vs Closed Reduction of the Syndesmosis
Christopher Del Balso, MBBS, MSc, FRCSC, Al-Walid Hamam, MD, FRCSC, Moaz Bin Yunus Chohan, MBBS, MSc, Christina Tieszer, MSc, Abdel-Rahman Lawendy, MD, PhD, FRCSC, David William Sanders, MD, MSc, FRCSC
doi : 10.1177/1071100721990008
First Published February 9, 2021; pp. 877–885
The goal of the study was to compare radiographic and functional outcomes between conventional closed syndesmotic reduction and screw fixation with open reduction, direct repair of the anterior inferior tibiofibular ligament (AiTFL) and screw fixation. We hypothesized that open reduction with restoration of the AiTFL would provide an improved reduction with better radiographic and functional outcomes.

This study aimed to compare clinical and radiographic outcomes and recurrence rates after reverse proximal chevron metatarsal osteotomy (PCMO) for patients with hallux valgus (HV) with or without metatarsus adductus (MA). We hypothesized that patients with MA would have poorer outcomes and a higher radiographic recurrence rate than those without MA.

doi : 10.1177/1071100721996262
First Published March 10, 2021; pp. 929–934
The association between ankle fractures in elderly patients and low bone mineral density (BMD) has recently been recognized, but the effect of BMD on the postoperative outcome of these fractures is unknown. The aim of this study was to investigate the effect of BMD on the postoperative outcome of ankle fractures in elderly patients to evaluate the need for BMD screening.

First Published January 29, 2021; pp. 935–943
Short-term outcomes for the INBONE I and INBONE II tibial stems have been favorable. The INBONE-II talus has been shown to have lower reoperation and failure rates compared to its predecessor at short term follow-up. The purpose of the present study was to assess mid-term outcomes for the third generation, two component total ankle prosthesis at 5 to 9 years follow-up, evaluating both the tibial and talar components.
Presence of Neovascularization in Torn Plantar Plates of the Lesser Metatarsophalangeal Joints

First Published February 9, 2021; pp. 944–951
Recent surgical techniques have focused on anatomic repair of lesser toe metatarsophalangeal (MTP) plantar plate tears, yet it remains unknown whether the plantar plate has the biological capacity to heal these repairs. Therefore, a better understanding of the plantar plate vasculature in response to injury may provide further insight into the potential for healing after anatomic plantar plate repair. Recently, a study demonstrated that the microvasculature of the normal plantar plate is densest at the proximal and distal attachments. The purpose of this study was to compare the intact plantar plate microvasculature network to the microvasculature network of plantar plates in the presence of toe deformity using similar perfusion and nano–computed tomographic (CT) imaging methods.

Rotational ankle instability (RAI) is associated with the faster onset of severe ankle osteoarthritis via dysfunction of the anterior talofibular ligament, calcaneofibular ligament, and deltoid ligament. No specific clinical examination is available for RAI, and diagnostic imaging has limitations in evaluating ligament degradation. This study investigated the deltoid ligament degeneration using Hounsfield unit (HU) values on computed tomography (CT) images.
The Distribution of Posterior Malleolus Fracture Lines

The morphology and classification of posterior malleolus (PM) fractures remain controversial. An increasing number of studies have found that merely focusing on the fragment size does not lead to a satisfactory prognosis. This study aimed to demonstrate the fracture line and comminution zones of PM fractures using computed tomography (CT), in order to provide insights into the injury mechanism of PM fractures.
