ABSTRACT
BACKGROUND: Total knee arthroplasty (TKA) for solid organ transplant (SOT) patients is becoming more prominent as life expectancy in this population increases. However, data on long-term (10 year) implant survivorship in this cohort are sparse. The purpose of this study was to compare 90-day, 2-year, 5-year, and 10-year implant survivability following primary TKA in patients who did and did not have prior SOT. METHODS: The PearlDiver database was utilized to query patients who underwent unilateral elective TKA with at least 2 years of active follow-up. These patients were stratified into those who had a SOT before TKA and those who did not. The SOT cohort was propensity-matched to control patients based on age, sex, Charlson Comorbidity Index, and obesity in a 1:2 ratio. Cumulative incidence rates and hazard ratios (HRs) were compared between the SOT, matched, and unmatched cohorts. RESULTS: No difference was observed in 10-year cumulative incidence and risk of all-cause revision surgery in TKA patients with prior SOT when compared to matched and unmatched controls. Compared to the matched control, the SOT cohort had no difference in the risk of revision when stratified by indication and timing. However, when compared to the unmatched control, patients who had prior SOT had a higher risk for revision due to periprosthetic joint infection at 10 years (HR: 1.80; 95% confidence interval: 1.17 to 2.76) as well as all-cause revision within 90 days after TKA (HR: 1.93; 95% confidence interval: 1.10 to 3.36). CONCLUSIONS: Prior SOT patients have higher rates of all-cause revision within 90 days and periprosthetic joint infection within 10 years when compared to the general population, likely associated with the elevated number of comorbidities in SOT patients and not the transplant itself. Therefore, these patients should be monitored in the preoperative and early postoperative settings to optimize their known comorbidities.
ABSTRACT
Congenital vertical talus (CVT) is the presence of rigid flatfoot deformity characterized by hindfoot valgus and equinus. This foot deformity is associated with midfoot dorsiflexion and forefoot abduction due to a fixed dorsal dislocation of the navicular relative to the head of the talus. It is often underdiagnosed in children due to its similarity to other disorders of the foot. Misdiagnosis of CVT and subsequent failure to address it leads to significant disability and pain. While past surgical management consisted of soft tissue releases that produced varying efficacy, current management of CVT consists of serial casting and minimally invasive procedures that have yielded excellent long-term outcomes. This review provides insight into the diagnosis and treatment of CVT with the intention of highlighting the importance of promptness of intervention to prevent further disability.
ABSTRACT
Current literature shows that the utilization of total hip arthroplasty (THA) to address pediatric hip pathology has seen a significant rise worldwide in recent decades. However, performing THA in pediatric patients presents unique challenges due to their increased activity levels, varying skeletal maturity, and diverse medical conditions. These challenges have relegated THA to a secondary option for young patients. Nonetheless, despite these difficulties, recent studies have demonstrated a growing prevalence of THA in pediatrics. Consequently, there is an urgent need for a comprehensive review of the existing literature on this topic. In this study, we examined large database and single-institution studies involving pediatric patients aged 21 years and under who underwent THA. The primary indications for THA in this population were osteoarthritis, osteonecrosis, and inflammatory arthritis. To ensure informed decision-making for pediatric patients, it is crucial to gather consolidated information on trends and outcomes related to THA indications. This review aims to provide insights into these trends and facilitate better decision-making for the treatment of pediatric patients.
