BACKGROUND AND PURPOSE The reported outcomes of hip resurfacing arthroplasty (HRA) vary. The frequency of this procedure in Denmark, Norway, and Sweden is low. We therefore determined the outcome of HRA in the NARA database, which is common to all 3 countries, and compared it to the outcome of conventional total hip arthroplasty (THA). METHODS The risk of non-septic revision within 2 years wa...

Two cases of dislocation of total knee arthroplasty presented to us within the same week. The first patient is a 71-year-old woman who underwent bilateral primary total knee arthroplasty. The left knee dislocated three weeks after the surgery. Due to failure of conservative measures, she underwent revision total knee arthroplasty. The other patient is a 72-year-old woman presenting ten years af...

Total shoulder arthroplasty is a common treatment for glenohumeral arthritis. One of the most common failure modes of total shoulder arthroplasty is glenoid loosening, causing postoperative pain, limitation of function, and potentially, the need for revision surgery. The literature has devoted considerable attention to the design of the glenoid component; efforts to better understand the biomec...

UNLABELLED The popularity of total knee arthroplasty combined with the aging US population indicates a dramatic increase in revision TKA procedures. Our objective was to project revision surgery costs in the United States, and to estimate the financial burden for hospitals historically under-reimbursed for these complex surgical procedures. Inflation adjusted charge data derived from a series o...

BACKGROUND The purpose of this study was to evaluate the clinical and radiographic outcomes of hip resurfacing patients and compare them to standard primary total hip arthroplasty procedures performed during the same period of time. METHODS One hundred and fourteen consecutive men who had a mean age of 50 years (range, 20 to 85 years) and who had undergone 120 hip resurfacing arthroplasties b...

BACKGROUND The use of larger femoral heads has been proposed to reduce the risk of dislocation after total hip arthroplasty, but there is a lack of evidence to support this proposal. The aim of this multicenter randomized controlled trial was to determine whether the incidence of dislocation one year after total hip arthroplasty is significantly lower in association with the use of a 36-mm femo...

INTRODUCTION Two-stage revision arthroplasty is today considered as the gold standard for control of chronic deep prosthetic infection. Although the revision arthroplasty should only be considered when infection is eliminated, the diagnosis of residual infection prior to the revision remains a challenging problem. MATERIALS AND METHODS We evaluated triple-phase bone scintigraphy as a useful d...

Eighty-six reverse shoulder arthroplasty (RSA) cases performed through a deltopectoral (DP) approach were reviewed at an average of 17.2 months after surgery. All procedures were performed by 2 fellowship-trained shoulder surgeons who perform a high volume of shoulder arthroplasty. We describe the surgical technique for the DP approach for primary and revision RSA, preliminary results, intraope...

INTRODUCTION Mechanical failure of femoral stems of revision hip arthroplasty has been rarely reported. In the current study, the cause of two stem fractures, which occurred in vivo, was analysed with use of clinical and radiological data, and the functional result after revision is presented. CASE REPORT Two patients, A 70-year-old male and a 73-year-old female, both of Mediterranean ethnic,...

v C t a urrently, there are no reported results of patients ithout overt infection who had a positive intraoperaive culture during revision shoulder arthroplasty. We herefore reviewed the intraoperative and preoperative nvestigations as well as the postoperative course of hese patients who had positive intraoperative cultures. e reviewed the results of 75 shoulders without overt nfection that u...
