Increase in the Tibial Slope Reduces Wear after Medial Unicompartmental Fixed-Bearing Arthroplasty of the Knee
Introduction. Unicompartmental arthroplasty of the knee in patients with isolated medial osteoarthritis gives good results, but survival is inferior to that of total knee prosthesis. Knees may fail because positioning of the prosthesis has been suboptimal. The aim of this study was to investigate the influence of the tibial slope on the rate of wear of a medial fixed-bearing unicompartmental kn...
متن کاملUnicompartmental Knee Osteoarthritis (UKOA): Unicompartmental Knee Arthroplasty (UKA) or High Tibial Osteotomy (HTO)?
Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis. Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...
متن کاملFinite Element Analysis of Mobile-bearing Unicompartmental Knee Arthroplasty: The Influence of Tibial Component Coronal Alignment.
BACKGROUND Controversies about the rational positioning of the tibial component in unicompartmental knee arthroplasty (UKA) still exist. Previous finite element (FE) studies were rare, and the results varied. This FE study aimed to analyze the influence of the tibial component coronal alignment on knee biomechanics in mobile-bearing UKA and find a ration range of inclination angles. METHODS A...
متن کاملPeriprosthetic fracture of the tibial plateau after unicompartmental knee arthroplasty.
The authors report three cases of unicompartmental knee arthroplasty (UKA), complicated with peri-operative periprosthetic fracture of the tibial plateau. The surgical technique was held responsible in all cases. The initial treatment was different in every case; all patients ultimately underwent revision total knee arthroplasty with a good functional outcome. The authors emphasise the importan...
متن کاملLong- Stem Total Knee Arthroplasty for Proximal Tibial Stress Fractures in the Elderly Patients
Background: Presentation of proximal tibia stress fracture is not infrequent among elderly patients due to their poorbone stock. Optimal management of patients with severe gonarthrosis of the knee and concurrent tibial stress fracture isnot known yet. In this study we report the outcome of primary total knee arthroplasty (TKA) using stemmed componentsin elderly patients.Methods: Between 2009 an...
