Outpatient Simultaneous Bilateral Unicompartmental Knee Arthroplasties: Safe With Positive Patient-Reported Outcomes.

Background: Bilateral unicompartmental knee arthroplasty (bUKA) done on the same day (simultaneous bUKA [sbUKA]) has been shown to be safe and cost-effective in hospital settings. Given the popularity and increased use of ambulatory surgery centers (ASCs), the purpose of this study was to compare safety and patient-reported outcome measures of sbUKA done at the hospital versus ASC.

Methods: Consecutive primary sbUKAs over five years done by a single surgeon were retrospectively collected.

Risk Factors for Midfoot Arthritis Associated With Medical History by Weight Bearing Computed Tomography.

Tarso-metatarsal joints and naviculocuneiform joints comprising midfoot is the second most commonly involved joints following the first metatarsophalangeal joint in the foot. However, related factors of midfoot arthritis (MA) have been rarely reported. The bony structure and alignment can be more precisely assessed using Weight-Bearing Computed Tomography (WBCT) than conventional radiographs.

Prevalence of midfoot arthritis and lesser toe deformities.

Background: The aim of this study was to investigate the epidemiology of Midfoot Arthritis (MA) and Lesser toe deformity (LTD) using Weight-Bearing Computed Tomography (WBCT).

Methods: 606 cases (247 male, 359 female) among 1316 consecutive cases with WBCT data from September 2014 to April 2022 were retrospectively reviewed at a single referral institution. The Cochran-Armitage test was performed to evaluate the trend of prevalence with respect to age group and obesity classification.

Staged reconstruction of the hallux for infected non-union using bulk autograft and a customized implant: Case report.

This case report illustrates the outcome of a deep infection following internal fixation of a fracture of the big toe. Hallux amputation could be avoided through staged salvage procedure. This paper can assist readers on how to effectively and safely recognize and treat this type of injury.

Risks of injury in distal metatarsal minimally invasive osteotomy when comparing standard and modified techniques: A cadaveric study.

Background: The objectives of the study were to evaluate the structures at risk in distal metatarsal mini-invasive osteotomy (DMMO) and to compare standard and intraosseous approaches.

Methods: DMMO was performed on the second and fourth metatarsals of 11 fresh-frozen cadaveric specimens. The standard technique was performed in 11 metatarsals.

Weightbearing Computed Tomography for Assessment of Foot and Ankle Deformities: The Iowa Experience.

Background: Weightbearing computed tomography (WBCT) is a reliable and precise modality for the measurement and analysis of bone position in the foot and ankle, as well as associated deformities. WBCT to assess three dimensional relationships among bones allowed the development of new measurements, as the Foot and Ankle Offset (FAO), which has high inter and intra-rater reliability. This study reports the University of Iowa's experience utilizing WBCT for the care of foot and ankle patients by describing its utility across different orthopedic diseases in improving diagnostic assessment, aiding surgical planning, and expanding the use for objective clinical follow-up.

Distal Tibiofibular Syndesmotic Widening in Progressive Collapsing Foot Deformity.

Background: Lateral overload in progressive collapsing foot deformity (PCFD) takes place as hindfoot valgus, peritalar subluxation, and valgus instability of the ankle increase. Fibular strain due to chronic lateral impingement may lead to distraction forces over the distal tibiofibular syndesmosis (DTFS). This study aimed to assess and correlate the severity of the foot and ankle offset (FAO) as a marker of progressive PCFD with the amount of DTFS widening and to compare it to controls.

Assessment of Posterior and Middle Facet Subluxation of the Subtalar Joint in Progressive Flatfoot Deformity.

Background: Adult acquired flatfoot deformity (AAFD) is a complex 3-dimensional pathology characterized by peritalar subluxation (PTS) of the hindfoot. For many years, PTS was measured at the posterior facet of the subtalar joint. More recently, subluxation of the middle facet has been proposed as a more accurate and reliable marker of symptomatic AAFD, enabling earlier detection.
