INTRODUCTION: This study aimed to (1) report the rates of resistance against a variety of antibiotics for pure Staphylococcal infections, and (2) examine the impact of ALBC use at primary surgery has on resistance patterns for patients undergoing first-time revision of primary hip and knee arthroplasty for indication of infection. MATERIALS AND METHODS: Data from the National Joint Registry database for England and Wales were linked to microbiology data held by Public Health England to identify a consecutive series of 258 primary hip and knee arthroplasties performed between April 2003 and January 2014 that went on to have a revision for Staphylococcal deep periprosthetic infection...

OBJECTIVE: To determine whether the timing and also duration of statin exposure following total hip/knee arthroplasty (THA/TKA) influences the risk of revision arthroplasty. METHODS: Subjects from the Clinical Practice Research Datalink, a large population-based clinical database, who had THA/TKA from 1988-2016 were included. Propensity score adjusted Cox regression models were used to determine the association between statin exposure and the risk of revision THA/TKA, i) at any time and ii) if first exposed 0-1, 1-5, or >5 years following THA/TKA...

BACKGROUND: Historically, infection control rates with debridement and component retention have been poor in the management of acute prosthetic joint infections. We previously described a 2-stage debridement with prosthesis retention protocol for acute periprosthetic joint infection and reported a 90% success rate in a sample of 20 patients. METHODS: A retrospective review of 83 patients who underwent a 2-stage debridement with implant retention with a minimum 1-year follow-up was performed...

Morbidly obese patients undergoing total knee arthroplasty have worse functional outcomes and implant survival, and increased revision rates compared with nonobese patients. In addition to increased medical comorbidities and difficult exposure, increased stress on the tibial implant and altered kinematics of knee motion contribute to aseptic loosening and medial collapse. Increased implant fixation, including use of a stemmed tibial implant, may be a way to help avoid these complications. While there is limited data on tibial stems in the morbidly obese patients specifically, cemented stemmed tibial implants should be strongly considered in these patients, especially if bone quality is poor...

Relative value units (RVUs) are used for ensuring that physicians are appropriately reimbursed based on case complexity. While past research has elucidated that surgeons are reimbursed at a higher rate for primary total knee arthroplasty (TKA) versus revision TKA, no study has explored differences in reimbursements between single-component and double-component revisions, considering a double-component revision is likely to require more effort/skill as compared with single-component revision. The 2015 to 2016 American College of Surgeons National Surgical Quality Improvement Program files were queried using Current Procedural Terminology (CPT) codes for single-component revision TKA (CPT-27486) and double-component revision TKA (CPT-27487)...

BACKGROUND: Suboptimal implant rotation has consequences with respect to knee kinematics and clinical outcomes. We evaluated the functional outcomes of revision total knee arthroplasty (TKA) for poor axial implant rotation. METHODS: We retrospectively reviewed 42 TKAs undergoing aseptic revision for poor axial implant rotation. We assessed improvements in Knee Society Score (KSS) and final range of motion (ROM). Subgroup analyses were performed for preoperative instability and stiffness, as well as the number of components revised and level of implant constraint used...

INTRODUCTION: Periprosthetic joint infections are a major challenge for treating physicians. Musculoskeletal infections with Mycobacterium bovis are extremely rare, with an assumed incidence of 0.08-0.1%. Consequently, periprosthetic joint infections with Mycobacterium bovis are even less frequent. Fungal periprosthetic joint infections are very rare. No cases of Candida guilliermondii infection of implanted prostheses are described in the literature. CASE PRESENTATION: An 87-year-old Swiss man with German ethnic origin suffered from symptoms of osteoarthritis of the knee...

BACKGROUND: Surgeons may "usually" resurface the patella during total knee arthroplasty (TKA), "rarely" resurface, or "selectively" resurface on the basis of certain criteria. It is unknown which of these 3 strategies yields superior outcomes. Utilizing New Zealand Joint Registry data, we investigated (1) what proportion of surgeons employs each of the 3 patellar resurfacing strategies, (2) which strategy is associated with the lowest overall revision rate, and (3) which strategy is associated with the highest 6-month and 5-year Oxford Knee Score (OKS)...

BACKGROUND: Preoperative opioid use results in adverse outcomes and higher costs after elective surgery. However, duration thresholds for higher risk are not entirely known. Therefore, the purpose of our study was to determine the number and duration of preoperative opioid prescriptions in order to estimate the risk of postoperative adverse events after major joint replacement and lumbar fusion. METHODS: National insurance claims data (2007 to September 30, 2015) were used to identify primary total knee arthroplasties (TKAs), total hip arthroplasties (THAs), and 1 or 2-level posterior lumbar fusions (PLFs) performed for degenerative disease...

As it is mentioned in the literature, rates of complications and revision are higher in the obese compared to non-obese patients, although obesity does not a contraindication for unicompartmental knee arthroplasty and successful outcomes are achieved. However, there is not any study in the literature comparing the outcomes of fixed and mobile unicompartmental prostheses which are applied in the obese patients. Objective of this study was to compare outcomes of our obese patients who we applied fixed or mobile unicompartmental arthroplasty and followed up for 8 years and over...

Although patellectomy is a rarely performed surgical procedure, patients may still progress to develop osteoarthritis of the tibiofemoral compartments leading to total knee replacement surgery. Due to the mechanical disadvantage of a previous patellectomy, it has previously been suggested that a prosthesis with more constraint should be used, however, there are conflicting reports in the literature. We aimed to assess the effects of stability following total knee replacement in patellectomised knee with revision as a primary endpoint...

The use of rotating-hinge systems in total knee arthroplasty is most often seen in revision setting where excessive bone loss, ligamentous instability and/ or extensor mechanism dysfunction may necessitate an increased level of component constraint. However, this implant type is also being increasingly used in the primary setting. The aim of this study is to review literature concerning the use of third generation rotating-hinge devices focusing on the indications for primary cases. Literature was searched for following search terms: total knee arthroplasty, primary indication, constraint, rotating hinge knee, knee prosthesis, hinged knee, total knee replacement...
