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. 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 eighteen were selected and revi...

Obesity is an epidemic across both the developed and developing nations that is possibly the most important current public health factor affecting the morbidity and mortality of the global population. Obese patients have the potential to pose several challenges for arthroplasty surgeons from the standpoint of the influence obesity has on osteoarthritic symptoms, their peri-operative m...

The most common pathogens in surgical site infections after total hip and knee arthroplasty are methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and coagulase-negative staphylococci. Patients colonized with MSSA or MRSA have an increased risk for a staphylococcal infection at the site of a total hip or knee arthroplasty. Most colonized individuals 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. ...

two cases of dislocation of total knee arthroplasty presented to us within the same week. the first patient is a 71year-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 aft...

The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optima...

The increasing frequency of joint arthroplasty has led to an increasing requirement for revision surgery. When treating an aseptically failed elbow arthroplasty one of the main issues is poor or absent proximal ulna bone stock, due to osteolysis. We report our experience with the use of strut allograft reconstruction of the proximal ulna, as an adjunctive procedure to non-custom revision total ...

Background: Aim of this study was to compare the clinical and radiological long-term outcomes following operativetreatment of comminuted radial head fractures using 1) primary radial head resection arthroplasty, 2) acute radial headresection, or 3) necessary secondary prosthetic removal. Additionally, we evaluated complex radial head fracturescombined with elbow dislocation and verified the hyp...

TEACHING OBJECTIVES: To review the current concepts of shoulder arthroplasty. To review the normal post-operative appearance of shoulder arthroplasty including materials, design, and function. To review the imaging appearance of common complications. CONTENTS: Prosthesis material, design, and terminology Preoperative imaging assessment Normal post-operative imaging appearance Imaging findings o...

Early attempts at spinal arthroplasty in the 1950s yielded limited success. A revival of this procedure occurred in the 1980s and became a realistic treatment option in the 1990s. Both lumbar and cervical arthroplasties have been introduced in the US since 2000 for randomized, prospective studies in accordance with the Food and Drug Administration (FDA) investigational device exemption provisio...
