Does a Previous High Tibial Osteotomy (HTO) Influence the Long-term Function or Survival of a Total Knee Arthroplasty (TKA)?
High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis ofthe knee with varus malalignment. The outcome of total knee arthroplasty (TKA) after HTO remains uncertain.The aim of this paper is to revise the literature with the aim of answering the following question: Does a previous (HTO)influence the long-term function or survival of a TKA?. The sea...
متن کاملFabella Fractures after Total Knee Arthroplasty with Correction of Valgus Malalignment
The incidence of fabella fractures is considered to be extremely low. This report presents two patients with femorotibial osteoarthritis and considerable preoperative valgus malalignment, who developed a fracture of the fabella (as demonstrated by radiography) after total knee arthroplasty with intraoperative correction of the valgus malalignment. Special attention should be paid to the fabella...
متن کاملThe cost-effectiveness of computer-assisted navigation in total knee arthroplasty.
BACKGROUND Total knee arthroplasty is one of the most clinically successful and cost-effective interventions in medicine. However, implant malalignment, especially in the coronal plane, is a common cause of early failure following total knee arthroplasty. Computer-assisted surgery has been employed during total knee arthroplasty to improve the precision of component alignment. The purpose of th...
متن کاملComputational study on the effect of malalignment of the tibial component on the biomechanics of total knee arthroplasty
OBJECTIVES Malalignment of the tibial component could influence the long-term survival of a total knee arthroplasty (TKA). The object of this study was to investigate the biomechanical effect of varus and valgus malalignment on the tibial component under stance-phase gait cycle loading conditions. METHODS Validated finite element models for varus and valgus malalignment by 3° and 5° were deve...
متن کاملDoes malalignment affect patient reported outcomes following total knee arthroplasty: a systematic review of the literature
BACKGROUND Total knee replacement is an effective treatment for knee arthritis. While the majority of TKAs have demonstrated promising long-term results, up to 20 % of patients remain dissatisfied with the outcome of surgery at 1 year. Implant malalignment has been implicated as a contributing factor to less successful outcomes. Recent evidence has challenged the relationship between alignment ...
