David P Gwynne-Jones, Heath W R Lash, Andrew W James, Ella E Iosua, John A Matheson
BACKGROUND: There are relatively few 20-year results of uncemented acetabular components, and most of these are modular designs. This study reports the 20-year results of a monoblock press-fit acetabular component. METHODS: A total of 122 total hip arthroplasties (111 patients) using the Morscher cup were reviewed at a mean of 19.7 years. The average age at implantation was 57.3 years (range, 36-74 years), and 81 (66%) were men. RESULTS: Twenty-two patients (25 hips) had died...

BACKGROUND: It is unknown to what extent diabetes mellitus modifies the long-term risk of aseptic loosening in total hip arthroplasty (THA) and total knee arthroplasty (TKA). We examined the association between diabetes mellitus, perioperative hyperglycemia, and the likelihood of revisions for aseptic loosening. METHODS: We studied 16,085 primary THA and TKA procedures performed at a large tertiary care hospital between 2002 and 2009. All blood glucose values around the time of surgery (within 1 week) were retrieved...

BACKGROUND: Periprosthetic joint infection (PJI) remains one of the most challenging and devastating modes of failure after total hip and knee arthroplasties. Despite the profound urgency and impact of PJI on an individual and societal basis, historically, there have not been standardized definitions of and diagnostic algorithms for infection after total joint arthroplasty. METHODS: In a recent symposium, the American Academy of Hip and Knee Surgeons put forth a standardized approach to the prevention, diagnosis, and management of the patient with a suspected PJI...

BACKGROUND: Tranexamic acid (TXA) has been associated with decreased blood loss and transfusion after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to examine both transfusion utilization and the economic impact of a Process Improvement Project implementing TXA for THA and TKA. METHODS: After standardization of TXA administration in THA and TKA patients, retrospective data were compared from 12 consecutive months before (group A, n = 336 procedures) and after (group B, n = 436 procedures) project initiation...

BACKGROUND: There is interest in uncemented total knee arthroplasty due to the hope for long-term biologic fixation, but limited data are available regarding uncemented tantalum patellar components. The purpose of this study was to evaluate the radiographic outcomes of uncemented tantalum patellar implants at midterm follow-up. METHODS: We retrospectively reviewed a consecutive series of 30 knees in 29 patients who underwent cementless total knee arthroplasty with an uncemented metal-backed tantalum patella between September 2006 and April 2009...

BACKGROUND: Functional recovery monitoring after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is often limited to surgeon-based assessment and patient self-reporting rather than objective measures. However, traditional outcomes may not reliably gauge return of function. The goal of this study was to evaluate and compare an objective measure of postoperative recovery, daily step-count, with patient self-reported outcomes. METHODS: Prospectively, 589 patients used a mobile step-tracking application to record daily steps...

BACKGROUND: Proximal tibia arthroplasty is associated with high rates of infection. This study is the largest one that has compared the infection rates with titanium vs silver-coated megaprostheses in patients treated for sarcomas. METHODS: The infection rate in 98 patients with sarcoma or giant-cell tumor in the proximal tibia who underwent placement of a titanium (n = 42) or silver-coated (n = 56) megaprosthesis (MUTARS) was assessed, along with the treatments administered for any infection...

BACKGROUND: Inclusion of patient satisfaction scores in setting reimbursements has been suggested by health care policy makers to contain cost and improve outcomes. The Short Form 36 Health Survey (SF-36) score provides a health-related quality of life (HRQoL) measure of arthroplasty outcome. Although previous work identified factors that influence this score for hip and knee arthroplasty patients, they did not focus on how a surgeon might use this information in a clinical setting. The present study examined whether relatively simple criteria might identify patients more likely to experience minimal HRQoL improvement...

BACKGROUND: Modular junctions in total hip arthroplasties have been associated with fretting, corrosion, and debris release. The purpose of this study is to analyze damage severity in total knee arthroplasties of a single design by qualitative visual assessment and quantitative material loss measurements to evaluate implant performance and patient impact via material loss. METHODS: Twenty-two modular knee retrievals of the same manufacturer were identified from an institutional review board-approved database...

BACKGROUND: A subset of patients who undergo total knee arthroplasty (TKA) are on methadone maintenance. They require more and often unpredictable quantities of opioids to function as effective painkillers. This study aims to compare the opioid requirements and the immediate postoperative course for patients on methadone maintenance with those who are not, after a TKA. METHODS: A retrospective, case-control study was performed. From 2005 to 2010, 36 patients, who underwent a unilateral TKA, on chronic methadone maintenance were identified...

BACKGROUND: Periprosthetic femur fractures after primary and revision total hip arthroplasty (THA) are one of the most common long-term reasons for reoperation after THA. Previous investigations have analyzed the incidence and risk factors of these fractures. No previous study, however, has analyzed a variation in periprosthetic femur fractures between meteorologic seasons. The aim of this study was to compare the incidence of periprosthetic femur fractures after primary and revision THAs depending on the meteorologic season...

P Maxwell Courtney, Gwo-Chin Lee
BACKGROUND: Kinematic alignment in total knee arthroplasty (TKA) seeks to more anatomically align the knee prosthesis to promote more physiological kinematics. However, there are questions about the durability, function, and complication rate of a non-mechanically aligned TKA. Therefore, the purpose of this study is to perform a systematic review and meta-analysis to evaluate early outcomes after kinematic alignment. METHODS: Two independent reviewers performed a systematic review of the English literature using both the MEDLINE and Embase databases searching for studies on kinematic TKA...

BACKGROUND: Despite the excellent outcomes associated with primary total hip arthroplasty (THA), implant failure and revision continues to burden the healthcare system. THA failure has evolved and displays variability throughout the literature. In order to understand how THAs are failing and how to reduce this burden, it is essential to assess modes of implant failure on a large scale. Thus, we report: (1) etiologies for revision THA; (2) frequencies of revision THA procedures; (3) patient demographics, payor type, and US Census region of revision THA patients; and (4) the length of stay and total costs based on the type of revision THA procedure...

BACKGROUND: Indications for hip arthroscopy in mildly dysplastic patients with a symptomatic hip remain controversial. METHODS: This article provides a concise review of the available literature evaluating the role of hip arthroscopy in treating symptomatic dysplasia. Potential indications for hip arthroscopy in isolation are reviewed. Emerging evidence on the role of hip arthroscopy based on patient-specific pathomorphology is highlighted. RESULTS: Hip arthroscopy in isolation may be helpful for select dysplastic patients with dynamic impingement or microinstability...

BACKGROUND: Bone mineral density (BMD) loss around femoral implants, particularly in the proximal femur, is a common outcome after total hip arthroplasty. Previous studies reported the prevention of postsurgical decrease in BMD with the use of osteoporosis drug therapy. This randomized study evaluated the efficacy of alendronate and alfacalcidol for preserving BMD over a long-term follow-up. METHODS: Sixty consecutive patients with hip osteoarthritis who had undergone primary cementless total hip arthroplasty were randomly assigned to an alendronate (n = 20), alfacalcidol (n = 18), or control (n = 22) group...

BACKGROUND: Readmission among Medicare recipients is a leading driver of healthcare expenditure. To date, most predictive tools are too coarse for direct clinical application. Our objective in this study is to determine if a pre-existing tool to identify patients at increased risk for inpatient falls, the Hendrich Fall Risk Score, could be used to accurately identify Medicare patients at increased risk for readmission following arthroplasty, regardless of whether the readmission was due to a fall...

BACKGROUND: The direct anterior approach (DAA) is becoming more popular as the standard surgical approach for primary total hip arthroplasty. However, it has been associated with an increased incidence of intraoperative femoral fractures in particular during the learning curve. Distal extension of the approach may be needed in case of intraoperative complications. The aim of the present study is to describe the distal extension of the DAA using the femoral interbundle technique. METHODS: A stepwise approach based on a cadaveric study to extend the DAA distally is presented...
