The traditional understanding of knee kinematics holds that no single fixed axis rotation exists in the knee. In contrast, a recent hypothesis suggests are better described simply as two simultaneous rotations occurring about axes. Knee flexion and extension occurs an optimal femur, whereas tibial internal external occur longitudinal tibia. No other translations or exist. This has been tested. Tibiofemoral were measured for 15 cadaveric knees undergoing realistic loadbearing activity...
Twenty fractures of the distal part femur proximal to a total knee replacement were treated operatively by members New England Trauma Study Group. Notching anterior aspect femoral cortex was associated with only two these fractures, and none prostheses loose at time fracture. All twenty open reduction stable internal fixation, operation on fifteen supplemented bone grafts. Every fracture healed, eighteen healed after mean sixteen weeks (range, six forty weeks). Union other delayed, but...
Component malrotation may result in unsuccessful total knee arthroplasty. We asked whether revision improves function patients with malrotated arthroplasty components. retrospectively reviewed 22 arthroplasties performed for femoral and/or tibial component malrotation. Revision surgery was within 2 years of the primary 81% cases (18 22) remainder 5 years. Although all had pain, 32% associated instability and 36% poor range motion. Average Knee Society Scores improved from 42 preoperatively...
Strain was measured in the normal anterior talofibular ligament (ATF) and calcaneofibular (CF) using Hall effect strain transducers five cadaveric ankles. These measurements were made both ligaments with ankle neutral position foot moving from 10° dorsiflexion to 40° plantarflexion an apparatus that permits physiologic motion. The then tested placed six different positions combined supination, pronation, external rotation, internal rotation. In position, through a range of motion...
Background: The Rejuvenate modular-neck stem implant (Stryker Orthopaedics, Mahwah, New Jersey) was recently recalled due to corrosion at the femoral neck-stem junction. purpose of this study investigate rate corrosion-related failure and survivorship analyze correlation patient factors with serum metal ion levels revisions. Methods: From June 2009 July 2012, 123 total hip arthroplasty stems (ninety-seven modular twenty-six non-modular) were implanted in 104 patients by a single surgeon....
Traditionally, the placement of tibial component in total knee arthroplasty (TKA) has focused on maximizing coverage surface. However, degree to which maximal affects correct rotational symmetric and asymmetric components not been well defined might represent an implant design issue worthy further inquiry.
Surgical navigation has been shown to improve the accuracy of bone preparation and limb alignment in total knee arthroplasty (TKA). Previous work effectiveness various types systems. Here, for first time, we assessed a novel imageless semiautonomous handheld robotic sculpting system performing resection TKA using cadaveric specimens. In this study, compared planned final implant placement 18 specimens undergoing new tool. Eight surgeons carried out procedures three designs. A quantitative...
Aims Infection complicating primary total knee arthroplasty (TKA) is a common reason for revision surgery, hospital readmission, patient morbidity, and mortality. Increasing incidence of methicillin-resistant Staphylococcus aureus (MRSA) particular concern. The use vancomycin as prophylactic agent alone or in combination with cephalosporin has not demonstrated lower periprosthetic joint infection (PJI) rates, partly due to timing dosing intravenous (IV) administration, which have proven...
Optimizing coverage of the resected tibial plateau is an important consideration in total knee arthroplasty. The eight different tray designs was examined 35 specimens. When no component overlap permitted, average ranged from 76.4% to 80.8%. allowed slight overlap, a "surgical fit," 78.5% 85.5%. As group, six symmetric provided more than two asymmetric (p < 0.05). Areas poor were identified, and geometries compared. Asymmetric components are thought be anatomic nature therefore cover surface...
We report the results of a first-in-human phase 1 clinical study to evaluate TRL1068, native human monoclonal antibody that disrupts bacterial biofilms with broad-spectrum activity against both Gram-positive and Gram-negative species. The population consisted patients chronic periprosthetic joint infections (PJIs) knee or hip, including monomicrobial polymicrobial infections, are highly resistant antibiotics due biofilm formation. TRL1068 was administered via single pre-surgical intravenous...
Published studies of the human hip make frequent reference to normal pelvis and acetabulum. However, other than qualitative descriptions we found no clinically applicable published references describing a acetabulum; such information is important for designing certain kinds implants (eg, reconstruction cages). We describe method quantify, average, apply data gathered from specimens create standard representation ilium ischium. One hundred healthy hemipelves 50 skeletons were evaluated....
