To assess revision rates after knee arthroplasty we compared cumulative results from world wide clinical studies and arthroplasty registers from the 1960 up to now in one of the largest reviews ever [1]. We found, the overall revision rate at ten years was 6% for total knee arthroplasty (TKA) and17%for unicondylar protheses (UKA). Literature from non-register studies are biased regarding UKA [2...

Massive allograft can be a useful option in revision total joint arthroplasty for treatment of significant bone loss. In rare cases, revision hip and knee arthroplasty procedures can be performed simultaneously using massive allograft-prosthetic composites. We present an 18 year follow up of a patient who received a simultaneous revision hip and knee total femoral allograft and discuss recent l...

BACKGROUND AND PURPOSE Poor outcomes have been linked to errors in rotational alignment of total knee arthroplasty components. The aims of this study were to determine the correlation between rotational alignment and outcome, to review the success of revision for malrotated total knee arthroplasty, and to determine whether evidence-based guidelines for malrotated total knee arthroplasty can be ...

BACKGROUND AND PURPOSE There is no consensus on which type of shoulder prosthesis should be used in patients with rheumatoid arthritis (RA). We describe patients with RA who were treated with shoulder replacement, regarding patient-reported outcome, prosthesis survival, and causes of revision, and we compare outcome after resurfacing hemi-arthroplasty (RHA) and stemmed hemi-arthroplasty (SHA). ...

BACKGROUND Total joint arthroplasty is a highly efficacious and cost-effective procedure for moderate to severe arthritis in the hip and knee. Although patient characteristics are considered to be important determinants of who receives total joint arthroplasty, no systematic review has addressed how they affect the outcomes of total joint arthroplasty. This study addresses how patient character...

Stress fracture of the femoral neck is a rare complication of total knee arthroplasty. We report a case of femoral neck fracture following revision arthroplasty of the ipsilateral knee. Contributing factors may have been the patient's osteoporosis and a period of immobilisation before the revision arthroplasty. The patient was treated successfully with hemiarthroplasty of the hip. In patients w...

Issue 1: Arthroplasty vs ORIF • Non-displaced or minimally displaced fractures-standard treatment is closed reduction and internal fixation in all ages. o Hudson, CORR, 1998. At 8 year f/u  Nondisplaced treated with ORIF-no difference in revision rate compared to arthroplasty  Displaced treated with ORIF – higher 8 year cumulative revision rate in older patients compared to arthroplasty o How...

PURPOSE To evaluate clinical results of two-stage revision using a modified articulating spacer for treatment of infected total knee arthroplasty (TKA). MATERIALS AND METHODS We retrospectively reviewed 20 cases treated by two-stage revision arthroplasty using a modified articulating spacer under the diagnosis of infected TKA from January 2006 to December 2011. The mean follow-up period was 2...

BACKGROUND Unicompartmental knee arthroplasty is a less-invasive alternative to total knee arthroplasty for patients with arthritis affecting only the medial or lateral compartment. However, little is known about recent trends in the use of these procedures and the associated outcomes among older patients. METHODS With use of a nationally representative 5% sample of Medicare beneficiaries who...

Setting and participants. A total of 1,453,493 Medicare Part A fee-for-service beneficiaries who underwent primary total hip arthroplasty and 348,596 who underwent revision total hip arthroplasty. For primary total hip arthroplasty, to select a population whose procedures were performed electively, patients with acute fractures and those admitted through the emergency department were excluded. ...
