BACKGROUND: The aim of this study was to present the long-term survivorship (20 years) of total elbow arthroplasty (TEA) for a relatively large population and to compare different prosthesis brands and patient subgroups. METHODS: Between 1994 and 2017, a total of 838 primary TEAs were reported to the Norwegian Arthroplasty Register. Implant survival was calculated using the Kaplan-Meier method. Risk differences were examined using Cox regression analyses and exact Cox regression for rare events...

Traditionally, diaphyseal stems have been utilized to augment the stability of revision total knee replacement (rTKR) implants. More recently metaphyseal augments, such as sleeves, have been introduced to further augment component fixation. The effect of augments such as stems and sleeves have on the primary stability of a rTKR implant is poorly understood, however it has important implications on the complexity, costs and survivorship of the procedure. Finite element analysis was used to investigate the primary stability and strain distribution of various size stems and sleeves used in conjunction with a cementless revision tibial tray...

Consistent evidence exists on the inutility of immediate postoperative radiographs after a total knee replacement (TKR). We hypothesized that eliminating the pre-discharge film would not have any effect on the postoperative patient outcomes. Retrospective analysis of prospectively collected data was performed on 220 knees. Patients undergoing a simple primary TKR operated by 2 surgeons (Surgeon A and B) from January 2013 to July 2015 were divided into 2 groups (Groups 1 and 2 having 112 and 108 knees respectively)...

Total knee arthroplasty has grown considerably over the past decade, due to the aging of the population, the increase in the prevalence of obesity, and an increasing demand. The 10-year revision rate is less than 5%. Functional outcomes, assessed by range of motion measures and functional scores, were significantly improved with the advent of more reliable and less invasive surgical techniques, better management of postoperative pain, and early high-intensity rehabilitation protocols. However, 20% of patients say they are dissatisfied with their knee replacement, either because of the persistence of pain, or because their function does not match their preoperative expectations...

Total knee arthroplasty (TKA) is a rewarding procedure in patients with hemophilia and end stage knee hemophilic arthropathy. However, this procedure might be associated with complications such as infection. There periprosthetic joint infection in patients with hemophilia is very well known, though we are not aware of any previous report on Brucella infection in this group of patients. Here, we reported a 28-year old man with Brucella infection of total knee replacement who initially underwent a conservative treatment followed bya two-stage revision...

M Gundry, S Hopkins, K Knapp
The link between low bone mineral density (BMD) scores leading to greater fracture risk is well established in the literature; what is not fully understood is the impact of total knee replacements/revisions or arthroplasties on BMD levels. This literature review attempts to answer this question. Several different databases using specific key terms were searched, with additional papers retrieved via bibliographic review. Based on the available evidence, total knee replacements/revisions and arthroplasties lower BMD and thus increase fracture risk...

BACKGROUND: Our objective in this study was to examine whether stakeholders further endorse the core domain set proposed by the Outcome Measures in Rheumatology Trials (OMERACT) total joint replacement (TJR) working group. METHODS: We emailed a survey to 3810 hip/knee arthroplasty patients and 49 arthroplasty surgeons at a high-volume arthroplasty center to rate the importance of each core domain (i.e., pain, function, patient satisfaction, revision surgery, adverse events, and death) and two additional domains (i...

OBJECTIVE: On a population level, the incidence of knee prostheses (KP) has increased, but excess health care costs per patient, compared to matched controls without a KP, in the years surrounding these procedures and their determinants are largely unknown. We therefore aimed to provide estimates of age and sex-specific incidence of KPs, revision KPs, and prosthesis complications in patients with knee osteoarthritis (OA) and to determine excess health care costs in the years surrounding surgery compared with matched controls...

Introduction: Group B Streptococcal (GBS) prosthetic joint infections (PJI) are rare, accounting for only 4.6-6% of primary and revision total knee replacements (TKRs). In 2015, there was an outbreak of GBS infections in Singapore with an association confirmed between consumption of Chinese-style raw fish dishes (snakehead fish, Asian bighead carp) and GBS infection, Type III GBS ST283 strain, affecting more than 200 patients in Singapore. This outbreak is the largest of its kind in the world and also the first time that foodborne transmission of GBS has been proven...

Introduction: Total femur arthroplasty (TFA) is a rare salvage limb procedure which serves as an effective alternative to limb amputation. Most commonly, it is indicated for oncologic orthopedic cases, and very few cases of a purely traumatic history for TFA have been documented. The decision to perform this complex procedure involves paying careful attention to reconstructive needs and functional expectations of the patient. Alternatives to this procedure are quite detrimental and include hip disarticulation and above-the-knee amputation...

Haemophilia is an inherited haemorrhagic disease characterized by the lack of coagulative factors associated nowadays mostly to musculoskeletal complications, particularly severe secondary arthritis in specific joints. Recurrent traumatic or spontaneous joint bleeding, induce severe arthropathy at a young age that can be treated only by joint replacement. Total knee or hip arthroplasty in young subjects may fail earlier due to wear or infections and in the haemophilic population, this means bone loss, pseudo tumours and the need of revision or even limb salvage surgery...

Background Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling...

Background and purpose - Fast-tracking shortens the length of the primary treatment period (length of stay, LOS) after total knee replacement (TKR). We evaluated the influence of the fast-track concept on the length of uninterrupted institutional care (LUIC) and other outcomes after TKR. Patients and methods - 4,256 TKRs performed in 4 hospitals between 2009-2010 and 2012-2013 were identified from the Finnish Hospital Discharge Register and the Finnish Arthroplasty Register. Hospitals were classified as fast track (Hospital A) and non-fast track (Hospitals B, C and D)...

BACKGROUND: Hindfoot arthritis or significant deformity involving the ankle and subtalar joint (STJ) is a disabling condition with few salvage options. Many surgeons note a decreased STJ fusion rate compared with ankle union when a retrograde nail construct is used. The purpose of this study was to report the STJ fusion rate of tibiotalocalcaneal (TTC) arthrodesis with retrograde nail. METHODS: A chart and radiographic review was performed. TTC fusions performed in patients with osteoarthritis, posttraumatic arthritis, or deformity correction with retrograde nail fixation were included...

OBJECTIVE: Despite the generalized use of prophylactic antibiotics in orthopaedic surgery, Surgical Site Infections (SSIs) are still a major source of morbidity, mortality, and hospital cost. This is due in part to the increasing prevalence of antibiotic resistant organisms. METHODS: A review of local epidemiology, the importance of an antibiotic stewardship program, patient optimization, and risk stratification options to reduce SSIs. RESULTS: The proportion of revisions due to infection is projected to rise rapidly over the next 25 years...

Despite the excellent success rates of the modern unicompartmental knee arthroplasty (UKA), results of knee replacement registries still shows a relatively high revision and failure rate for UKA, especially when compared with traditional total knee arthroplasty (TKA). Bearing dislocation continues to be advocated as the predominant mechanism of failure in mobile UKA, whereas polyethylene wear and aseptic loosening remains the main cause of failure of fixed UKA. Degeneration of the unreplaced compartments has been reported in both mobile and fixed designs...
