Cobalt toxicity after revision to a metal-on-polyethylene total hip arthroplasty for fracture of ceramic acetabular component

Arthroplasty Today, 2015
Cobalt metallosis after revision metal-on-polyethylene total hip arthroplasty for catastrophic failure of ceramic components is uncommon but a potentially devastating complication.

Prediction of the probability of revision hip arthroplasty with replacement of the acetabular component depending on the type of its cement fixation [PDF]

Гений oртопедии, 2019
Introduction One of the most common causes of revision hip arthroplasty is aseptic instability of the primary implant. The acetabular component of the implant is less stable, even if fixed with bone cement.

Management of pelvic discontinuity in revision total hip arthroplasty: a review of the literature

, 2015
Pelvic discontinuity is a complex problem in revision total hip arthroplasty. Although rare, the incidence is likely to increase due to the ageing population and the increasing number of total hip arthroplasties being performed.

Prior osteosynthesis—unlike osteotomy—raises revision risk after total knee arthroplasty, predominantly via periprosthetic infection

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee surgery is discussed as a risk factor for total knee arthroplasty (TKA), yet most reports do not distinguish between osteotomy and osteosynthesis. The German Operationen‐ und Prozedurenschlüssel (OPS)‐based classification was used to compare the impact of these procedures on implant survival, mortality and complications ...

MODERN TRENDS IN ORTHOPEDICS: REVISION OF THE ACETABULAR AND FEMORAL COMPONENTS

Travmatologiâ i Ortopediâ Rossii, 2012
The revision rate of total hip arthroplasty (THA) is increasing with growth of number primary THA. The problems of revision procedures are associated with high technical demands and high incidence of poor results.

Revision Total Hip Arthroplasty.

Orthopedics & Traumatology, 1997
We reviewed the results of 10 patients (10 hips) after revision total hip arthroplasty with use of cement for 6 aseptic loosenings, 2 septic loosenings, 1 femoral shaft fracture, and 1 component fracture. Three patients were men and 7 women. Their mean age was 73 years (range 56 to 86). The mean duration from primary operation to revision was 64 months

Predicting wear of UHMWPE: decreasing wear rate following a change in direction [PDF]

, 2011
Computational tools are emerging as design tools for the development of total joint replacement with improved wear performance. The current wear models of polyethylene assume that wear is linearly proportional to sliding distance; however, it is ...

Improved surgical accuracy in total knee arthroplasty using the ROSA® knee system: A randomised‐controlled unblinded trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Robotic‐assisted total knee arthroplasty (RATKA) has been connected to improved surgical precision and implant alignment compared to conventional TKA (CTKA), with limited evidence from randomised‐controlled trials (RCT) and a large range of different systems on the market. Consequently, this study aimed to compare RATKA using the ROSA®

Tapered modular fluted titanium stems for femoral fixation in revision total knee arthroplasty

Arthroplasty Today, 2018
Consensus regarding femoral stem fixation options in revision total knee arthroplasty remains controversial. Tapered, modular, fluted titanium (TMFT) stems have an excellent track record in total hip arthroplasty for their ability to provide axial and ...

Knee hyperextension is a sign of through‐range laxity and may be effectively managed without routine joint line distalisation in a robotic functional alignment workflow

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Traditional management of hyperextension deformity in total knee arthroplasty (TKA) involves routine under‐resection of distal femoral bone to lower the joint line and close the extension gap. This study aimed to assess how a robotic functional alignment (FA) workflow with pre‐resection gap assessment managed hyperextending knees to ...
