Locating the true flexion-extension axis of knee can play an important role in component placement a total arthroplasty, especially using contemporary computer-assisted surgical navigation. We determined if commonly used transepicondylar is accurate and reproducible substitute for axis. Twenty-three fresh-frozen cadaveric distal femurs with intact soft tissue were imaged computed tomography reconstructed three-dimensional virtual space. The was compared line equidistant from articular...

Objective The purpose of this study was to explore the relationship between patients' self-reported and performance-based function after total hip arthroplasty (THA). Design Twenty-three patients (age, 61.4 ± 8.3 yrs) undergoing primary THA for osteoarthritis participated. Self-reported recovery measured using Hip Disability Osteoarthritis Outcome Score activities daily living pain subscales. Performance-based functional measures included timed up go test, stair climbing 6-minute walk test....

Cefazolin is a first-line agent for prevention of surgical site infections (SSIs) after total joint arthroplasty. Patients labeled allergic to beta-lactam antibiotics frequently receive clindamycin or vancomycin perioperatively due the perceived risk hypersensitivity reaction exposure cefazolin.This single-system retrospective review included patients penicillin cephalosporin who underwent primary hip and/or knee arthroplasty between January 2020 and July 2021. A detailed chart was performed...

Background/Objectives: Reported patient results after total hip arthroplasty (THA) have been described as a function of surgical approach. Such commonly subjective. Though self-reported outcomes are value and often utilized, inclusion functional performance measures represents an objective measure to compare THA techniques. Methods: Patients that underwent primary surgery at our institution were grouped by approach (Direct Anterior vs Posterior). Patient data collected pre-operatively, well...

Objectives: Clinical trials have reported decreased blood loss with the use of tranexamic acid during joint reconstruction. The purpose this study was to assess individual practice implications in replacement surgery. Methods: Health records adults undergoing total knee arthroplasty and hip over a 12-month period were retrospectively reviewed. treatment group comprised patients who received intravenous perioperatively. control did not receive acid. Results: Patients (n = 64) 99) well matched...

Medial compartment knee osteoarthritis is a painful and debilitating disease. A proximal fibular osteotomy novel, simple surgical technique that may reduce pain improve function for patients with osteoarthritis. The purpose of this biomechanical cadaver study was to determine what effect had on joint ankle pressures tibia strain. Ten matched pairs legs were tested in compression 1.1 times body weight comparing intact at 0°, 15°, 30° flexion. Sensors inserted into the measure pressure, force,...

The primary aim of this article is to describe the structure and challenges Medicare Medicaid reimbursement for a total hip or knee arthroplasty within context Comprehensive Care Joint Replacement model. secondary aims are identify potential solutions overcome orthopedic surgeon, compare current projected structures procedures. Final decisions on as outlined by Centers & Services reviewed. impact these effect Services' payment surgeons organizations patient care highlighted. [Orthopedics....

Diabetes has negative effects on the outcomes of total joint arthroplasty, including increased numbers complications, decreased function, early revision, and higher costs. The prevalence diabetes is increasing rapidly worldwide; therefore, orthopaedic surgeon should have an understanding how affects surgical outcomes.

Total joint replacement is indicated to alleviate pain and disability associated with hip knee osteoarthritis. Arthroplasty outcomes are typically reported together, or anecdotal comparisons made between total arthroplasty (TKA) (THA) recovery. Limited data quantifies differences in recovery trajectories, especially respect performance-based outcomes. Seventy-nine people undergoing THA were followed over 6 months. Functional performance was measured using the stair climb test,...

Revision rates for total hip arthroplasty are increasing and pelvic discontinuity is estimated to be present in 1% 5% (Berry). Discontinuity defined as a separation of the cephalad portion pelvis from caudad (AAOS Type IV defects). This results bone loss secondary osteolysis, infection, fracture, or mechanical loosening. The goals revision surgery this setting obtain secure fixation acetabular component with without union discontinuity. Many methods exist treating problem. Results allograft...

Forced-air warming is used as a mechanism to prevent hypothermia and adverse outcomes associated with among patients undergoing surgery. Patient safety in healthcare includes the use of devices technology that minimize potential events patients. The present study sought compare capabilities patient between two different mechanisms warming: forced-air non-air warming.One hundred twenty total hip or knee arthroplasty received via forced device fabric conductive material. project was part...

Purpose: To investigate the effectiveness of home health physical therapy followed by outpatient as compared to patients discharged directly in improving functional performance, strength/activation and residual knee pain outcomes among who received a total arthroplasty.Materials methods: A secondary analysis longitudinal data which with arthroplasty underwent or were therapy. Main outcome measures included stair climb test, timed up go, 6-min walk quadriceps hamstring strength, activation...

Total knee arthroplasty (TKA) is the most common elective orthopedic surgery performed in United States. Following patients experience significant lower extremity swelling that related to poor satisfaction with and hypothesized contribute functional decline. However, practice, precise reliable methods for measuring do not exist. The purpose of this study was provide reliability precision parameters an innovative approach, single frequency bioelectrical impedance assessment (SF-BIA), post-TKA...

Abstract Background With recent Medicare payment changes, older adults are increasingly likely to be discharged home instead of extended care facilities after total joint arthroplasty (TJA), and may therefore at increased risk for readmissions. Identifying factors readmission could help re-align pathways vulnerable patients; research has suggested preoperative dependency in activities daily living (ADL) increase perioperative postoperative surgical complications. However, the proportion...

Abstract Loss of quadriceps strength after total knee arthroplasty (TKA) is most pronounced acutely but persists long‐term, negatively impacting physical function in daily activities. Neuromuscular electrical stimulation (NMES) early surgery an effective adjuvant to standard care rehabilitation (SOC) for attenuating loss following TKA, the mechanisms whereby NMES maintains are unclear. This work aimed determine effects on and skeletal muscle fiber size 2 weeks TKA compared SOC. Patients...

Osteoarthritis is a significant cause of disability, resulting in increased joint replacement surgeries and health care costs. Establishing benchmarks that more accurately predict surgical duration could help to decrease costs, maximize efficiency, improve patient experience. We compared the anesthesia-controlled time (ACT) surgery-controlled (SCT) primary total knee (TKA) hip arthroplasties (THA) between an academic medical center (AMC) community hospital (CH) for 2 orthopedic surgeons.
