In total knee arthroplasty (TKA), functional phenotypes are of interest regarding surgical alignment strategies. Functional were introduced in 2019 and consist limb, femoral, tibial phenotypes. The hypothesis this study was that mechanically aligned (MA) TKA changes preoperative phenotypes, which decreases the 1-year Forgotten Joint (FJS) Oxford Knee Score (OKS) increases WOMAC. All patients included had end-stage osteoarthritis treated with a primary MA TKA, supervised by four academic...
Alignment strategies for primary total knee arthroplasty (TKA) have changed significantly over time with a shift towards more individualized alignment goal. At the same time, computer-assisted surgery (CAS) has gained interest intraoperative control and accuracy in implant positioning limb alignment. Despite often discussed benefits drawbacks of robotics navigation TKA, routine use these new devices on day-to-day basis remains obscure. Therefore, nationwide hospital billing data based...
Background: Robotic assistance is considered capable of improving precision and outcomes total knee replacement. We assessed the inherent biases, pre-procedural planning accuracy using 2D to 3D X-Atlas®, final axis ROSA® Knee System (Zimmer Biomet, Warsaw, IN, USA). Methods: A 55 patients who underwent robotic-assisted replacement USA) at a single center were included. Pre-procedural measurements performed by ROSA compared those senior consultants. Component sizes predicted implanted....
The direct anterior approach (DAA) represents a well-recognized soft tissue sparing technique for primary total hip arthroplasty (THA). feasibility and suitability of the DAA in cases complex acetabular deformities, namely coxa profunda (CP) protrusio acetabuli (PA), remain to be determined.A 188 CP (100 cases) PA (88 hips undergoing THA via were retrospectively analyzed. Surgical radiographic parameters evaluated potential complications assessed. Finally, successful implantation was defined...
Direct anterior approach total hip replacement (DAA-THR) is gaining increased interest due to its tissue-sparing nature and rapid recovery. Obesity has been shown be a significant parameter influencing cup positioning in DAA-THR. It was the intention of this retrospective study examine how obesity would influence restoration native biomechanical parameters during A 74 patients from high-volume university orthopedic center after unilateral DAA-THA were included. Patients retrospectively...
Background : As advanced age often leads to accumulating comorbidities, geriatric patients are endangered by serious events during total hip arthroplasty. This study was conducted explore whether or not the benefit in terms of health-related quality life (HRQoL) comparable younger patients. Methods At a single academic center, 100 meeting following inclusion criteria were retrospectively recruited: (1) primary arthritis leading THA; (2) 80 years older at time surgery; (3) follow up least 12...
Rapidly destructive osteoarthritis (RDO) of the hip joint is characterised by rapid destruction femoral head with or without acetabular involvement. There has been increasing interest in this disease over past years; however, entity still poorly understood, and its pathophysiology remains unknown. Yet, there ample evidence today that increased bone metabolism might play a role onset progression disease. Vitamin D utmost importance to maintain balanced metabolism. However, whether vitamin...
Cartilage repair techniques for chondral defects in the hip are crucial treating conditions like femoroacetabular impingement, developmental dysplasia, and osteonecrosis, especially young patients to delay progression of osteoarthritis. This study aims present age sex distributions trends hip-preserving surgeries Germany from 2006 2022, analyzing 116,179 procedures using German OPS coding system. The were categorized into three groups: debridement, refixation, regeneration. Arthroscopy was...
Given the close functional connection between hip and spine, their simultaneous degenerative pathology is a common problem seen in orthopedic patients has been termed "hip spine syndrome". Demographic change an increasing number of operations have led to more who undergone both total arthroplasty spondylodesis especially lumbar spine. Studies shown significant dislocation rates this cohort as high almost 30%. Biomechanical studies considerations show that spinal surgery directly influences...
Abstract Purpose The Area Measurement And Depth Underlying Structures (AMADEUS) classification system has been proposed as a valuable tool for magnetic resonance (MR)‐based grading of preoperatively encountered chondral defects the knee joint. However, potential relationship this novel score with clinical data was yet to determine. It primary intention study assess correlative AMADEUS patient reported outcome scores in patients undergoing medial open‐wedge high tibial valgus osteotomy (HTO)....
Abstract Purpose There is little evidence proving the concept of partial weight-bearing to be efficient and feasible. Using insole pressure measurement systems, this study aimed explore compliance prescribed restrictions after total knee arthroplasty (TKA). Methods 50 patients TKA were recruited in a prospective manner. They advised limit affected limb 200 N. True load was measured via force-sensors on day one surgery (M1) before discharge (M2). Compliance rehabilitation protocol primary...
Total hip arthroplasty (THA) is commonly performed using off-the-shelf implants. In the case of a severe mismatch between anatomy proximal femur and geometry stem, use custom-made stems might become necessary. The goal this study was to investigate precision implantation one manufacturer (CTX AQ Implants) determine risk factors for malpositioning. All patients receiving CTX stem 2014 2020 at six high-volume academic centers were retrospectively recruited. achieved position as determined by...
Abstract Introduction The AMADEUS (Area Measurement And DEpth and Underlying Structures) score has advanced to a commonly used tool for MRI-based chondral defect severity grading prior cartilage knee surgery. It was the intention of this study assess potential correlation with clinical data by patient-reported outcome measures (PROMs). Methods A total 51 patients undergoing ACI (autologous chondrocyte implantation) between 2016 2022 were found eligible retrospectively analyzed. All...
BackgroundAseptic loosening is the most common mode of failure after total knee arthroplasty. Despite this, diagnosis often remains challenging and mainly relies on imaging modalities. Until today, no biomarker exists to aid in diagnosing implants. As zirconium found bone cement, where it serves as radiopacifier, this study aimed establish a synovial for loosened cemented prostheses.MethodsA 31 patients scheduled revision prostheses were included. In all patients, initial used cement...
The direct anterior approach (DAA) is a recognized technique for total hip arthroplasty (THA) that spares soft tissue. Functional and clinical outcomes following THA via the DAA in patients with complex acetabular deformities, specifically coxa profunda (CP) protrusio acetabuli (PA), have yet to be determined.
Several studies have reported a high prevalence of hypovitaminosis D in orthopedic patients. The purpose this prospective observational study was to report on the patients scheduled for elective primary total knee arthroplasty (TKA) and its associated risk factors.
Background: The aim of our study was to examine the combined effects tranexamic acid (TXA) and vancomycin powder (VP) on chondrocytes in vitro. Despite use TXA VP being linked a reduced risk extensive postoperative blood loss periprosthetic joint infections (PJIs) TKA, possible cytotoxic side periarticular cell types remain unclear. Methods: Human were harvested from hyaline cartilage expanded monolayer culture before simultaneously exposed different concentrations for varying exposure...
