    FAI February 2020: Effect of the Modified Lapidus Procedure on Pronation of the First Ray in Hallux Valgus

    FAI February 2020: Effect of the Modified Lapidus Procedure on Pronation of the First Ray in Hallux Valgus

    Hallux valgus (HV) is a triplanar deformity of the first ray including pronation of the first metatarsal with subluxation of the sesamoids. The purpose of this study was to investigate if a first tarsometatarsal fusion (modified Lapidus technique), without preoperative knowledge of pronation measured on weightbearing computed tomographic (CT) scans, changed pronation of the first metatarsal and determine if reduction of the sesamoids was correlated with changes in first metatarsal pronation.
    The modified Lapidus procedure was an effective tool to change pronation of the first ray. Reduction of the sesamoids was not associated with postoperative first metatarsal pronation.

    FAI January 2020: 3D, Weightbearing Topographical Study of Periprosthetic Cysts and Alignment in Total Ankle Replacement

    FAI January 2020: 3D, Weightbearing Topographical Study of Periprosthetic Cysts and Alignment in Total Ankle Replacement

    We investigated the association between hindfoot residual malalignment assessed on weightbearing computed tomography (WBCT) images and the development of periprosthetic cysts (PPCs) after total ankle replacement (TAR). We hypothesized that PPCs would be found predominantly medially in the varus configuration and laterally in the valgus configuration.
    In this series, the PPC volume after primary TAR significantly correlated with postoperative hindfoot malalignment and longer follow-up.

    FAI December 2019: Imaging of Bone Perfusion and Metabolism in Subjects Undergoing Total Ankle Arthroplasty Using 18F-Fluoride Positron Emission Tomography

    FAI December 2019: Imaging of Bone Perfusion and Metabolism in Subjects Undergoing Total Ankle Arthroplasty Using 18F-Fluoride Positron Emission Tomography

    Total ankle arthroplasty (TAA) continues to exhibit a relatively high incidence of complications and need for revision surgery compared to knee and hip arthroplasty. One common mode of failure in TAA is talar component subsidence. This may be caused by disruption in the talar blood supply related to the operative technique. The purpose of this study was to quantify changes in talar bone perfusion and turnover before and after TAA with the INBONE II system using 18F-fluoride positron emission tomography / computed tomography (PET/CT).
    Our study was the first to link 18F-fluoride PET/CT with pre-post evaluation of total ankle replacements. The study quantified perfusion within the talus beneath the TAA implant supporting the hypothesis that perfusion of the talus remained intact after surgery.

    FAI November 2019: Prospective Randomized Trial Comparing Mobile-Bearing and Fixed-Bearing Total Ankle Replacement

    FAI November 2019: Prospective Randomized Trial Comparing Mobile-Bearing and Fixed-Bearing Total Ankle Replacement

    Outcomes of total ankle replacement for the treatment of end-stage ankle arthritis continue to improve. Debate continues whether a mobile-bearing total ankle replacement (MB-TAR) or a fixed-bearing total ankle replacement (FB-TAR) is superior, with successful outcomes reported long term for MB-TAR and at intermediate- to long-term follow-up for newer generation FB-TAR. Although comparisons between the 2 total ankle designs have been reported, to our knowledge, no investigation has compared the 2 designs with a high level of evidence. This prospective, randomized controlled trial conducted at a single institution compares patient satisfaction, functional outcomes, and radiographic results of the mobile-bearing STAR and the fixed-bearing Salto-Talaris in the treatment of end-stage ankle arthritis.
    With a high level of evidence, our study found that patient-reported and clinical outcomes were favorable for both designs and that there was no significant difference in clinical improvement between the 2 implants. The incidence of lucency/cyst formation was similar for MB-TAR and FH-TAR for the tibial component, but the MB-TAR had greater talar lucency/cyst formation and tibial and talar subsidence. As has been suggested in previous studies, clinical outcomes do not necessarily correlate with radiographic findings. Reoperations were more common for MB-TAR and, in most cases, were to relieve impingement or treat cysts rather than revise or remove metal implants.

    FAI October 2019: Long-term Follow-up of Cheilectomy for Treatment of Hallux Rigidus

    FAI October 2019: Long-term Follow-up of Cheilectomy for Treatment of Hallux Rigidus

    Hallux rigidus is the most common arthritic condition in the foot. First metatarsophalangeal joint cheilectomy produces satisfactory results in retrospective studies with reported good to excellent results in up to 97% and pain relief and function in 92%. The results of cheilectomy for higher grades of hallux rigidus are less favorable. The purpose of this study was to evaluate the long-term functional results and survivorship of cheilectomy for treatment of hallux rigidus.
    Our study supports the use of cheilectomy for treatment of hallux rigidus (grade 1-3 Coughlin and Shurnas) as a reliable procedure with favorable results. At long-term follow-up, patients who underwent cheilectomy had a low revision rate and a moderately low rate of pain recurrence.

    FAI September 2019: Total Ankle Arthroplasty Survival and Risk Factors for Failure

    FAI September 2019: Total Ankle Arthroplasty Survival and Risk Factors for Failure

    Total ankle arthroplasty (TAA) is an increasingly selected treatment for end-stage ankle arthritis; however, failure and revision of the tibial and talar components remains an issue. Although multiple risk factors have been shown to contribute to early component revision, no study has looked at combining such risk factors into a predictive model that could potentially decrease revision rates and improve implant survival. This study aimed to develop a predictive model for TAA failure based on patient characteristics, patient-reported outcomes (PROs), and immediate postoperative radiographs.
    Our predictive model is based on a combination of patient factors, PROs, and radiographic TAA alignment. We believe it can be used by surgeons to predict failure in their TAA patients, thereby optimizing postoperative outcomes by improving patient selection and modifiable outcome-specific parameters.
