Article Abstract
Although mid- to long-term results after total ankle replacement have improved because of available second- and third-generation devices, failure of total ankle replacement is still more common compared with total hip replacement and total knee replacement. The portfolio of available total ankle replacement revision component options is small. Furthermore, the bone stock of the tibiotalar region is scarce making it difficult and in some situations impossible to perform revision total ankle replacement. In these cases tibiotalar and tibiotalocalcaneal fusions are valuable options. This article describes which surgical procedures should be performed depending on the initial situation and gives detailed advice on surgical technique, postoperative care, and clinical results.
Introduction: Total knee arthroplasty (TKA) in severe varus deformity still remains a challenge. Alternative alignment TKA aims to improve outcomes and satisfaction. The purpose of this study is to report on the outcomes of a functionally aligned TKA in severe varus deformity.
Objectives: This study aims to compare the radiographic results with and without postoperative metal augmentation in varus knee patients with primary total knee arthroplasty (TKA) with a hip-knee-ankle (HKA) angle >10° and to determine a cut-off value using radiographic parameters to predict the need for metal augmentation.
Patients And Methods: Between October 2022 and April 2024, a total of 87 knees (51 right and 36 left) of 82 patients (11 males, 71 females; mean age: 68.7±8 years; range, 53 to 86 years) who underwent primary TKA were retrospectively analyzed.
Aim: To evaluate the clinical efficacy and imaging outcomes of a domestically produced orthopedic surgical robot for total knee arthroplasty and to explore its applicability in patients with varying degrees of deformity.
Methods: This study retrospectively included 120 patients who underwent TKA at our hospital between February 2023 and June 2024. The patients were divided into a control group (conventional TKA surgery) and an observation group (robot-assisted TKA surgery), with 60 patients in each group.
Objectives: To investigate whether the effectiveness of progressive tendon loading exercises (PTLE) on patellar tendinopathy is mediated through changes in physical or imaging properties.
Design: Mediation analyses based on a randomized clinical trial (n = 76) in patellar tendinopathy comparing PTLE with eccentric exercise therapy (EET).
Methods: Pain-related disability on Victorian Institute of Sports Assessment-Patella (VISA-P, 0 to 100) and pain (Visual Analogue Score) after single-leg decline squat (VAS-SLDS, 0 to 10) at 24 weeks were outcome measures.
Background: Unrestricted kinematic alignment (uKA) in total knee arthroplasty (TKA) has the theoretical advantage of reproducing patients' constitutional alignment and restoring the pre-arthritic joint line position and obliquity. However, modifications of the original uKA technique have been proposed due to the potential risk of mechanical failure and instability. Given the significant variability in soft tissue behavior within the same bony morphology group, uKA pure knee resurfacing could be occasionally detrimental.
