The restoration of posterior femoral translation has been shown to be an important factor in enhancing knee flexion after total arthroplasty. purpose this study was compare the ranges motion associated with standard and high-flexion stabilized prostheses patients managed simultaneous bilateral arthroplasty.Fifty (mean age, sixty-eight years) received a fixed-bearing prosthesis one contralateral knee. Two were men, forty-eight women. At mean 2.1 years postoperatively, assessed clinically...

Background: The early experience with cementless total hip replacement led to design modifications increase the initial press-fit and stability of femoral component, reduce diameter head, improve acetabular including locking mechanism shell quality polyethylene liner. We performed a prospective study assess results in young patients who had been followed for minimum eight years after treatment primary arthroplasty second-generation prosthesis. Methods: Eighty (118 hips) were included study....

Although general guidelines have been proposed for proximal tibial and supracondylar osteotomies, double level osteotomy provides the advantage of maintaining neutral joint-line obliquity in addition to correcting limb malalignment around knee. The goal this prospective study was determine outcome knee performed after analysis with computer-aided preoperative planning software patients varus malalignment.Twenty-nine osteotomies were twenty-four patients. followed an average duration 82.7...

Background: Whether total knee arthroplasty with use of computer-assisted surgical navigation can improve the limb and component alignment is a matter debate. We hypothesized that superior to conventional regard precision implant positioning. Methods: Sequential simultaneous bilateral arthroplasties were carried out in 160 patients (320 knees). One was replaced system, other conventionally without navigation. The two methods compared for accuracy orientation components as determined by...

Background: The purpose of this prospective, randomized study was to evaluate the clinical and radiographic results associated with proximally porous-coated titanium stems that were identical in geometry but differed regard proximal surface treatment (with or without hydroxyapatite coating). Methods: A performed fifty patients (100 hips) who had undergone sequential bilateral primary total hip replacement. stem coating implanted on one side a other during same operative setting all patients....

The purpose of the current study was to directly compare results fixed-bearing and mobile-bearing total knee arthroplasties in same patient who had bilateral simultaneous replacements. A prosthesis (AMK) implanted one a (LCS) other 116 patients. average age patients 65 years (range, 33-70 years). followup 7.4 6-8 Clinical radiographic done using Knee Society Hospital for Special Surgery rating systems at 6 weeks, 3 months, 1 year after surgery, yearly thereafter. Total score, pain mean...

Background: Although the design features of high-flexion posterior cruciate-retaining and cruciate-substituting total knee prostheses reportedly improve range motion, a clinical comparison both systems with regard to motion has not been reported, our knowledge. The purpose present study was compare functional outcome in knees receiving either or prosthesis. Methods: Two hundred fifty patients (mean age, 71.6 years) received prosthesis one contralateral knee. Ten were men, 240 women. At time...

Background: There is limited information comparing the results of fixed-bearing total knee replacement and mobile-bearing in patients with osteoarthritis who are younger than fifty-one years have a implant one other. The purpose this study was to compare our long-term clinical radiographic group from population. Methods: We prospectively compared 108 were (mean age, forty-five years) had received prosthesis rotating platform mean follow-up 16.8 (range, fifteen eighteen years). assessed...

Abstract Background Probiotic therapies, mainly live bacteria, have been proven to be effective in treating atopic dermatitis (AD) with some controversies. Killed probiotics or postbiotics would immunomodulatory effect allergic diseases including AD. This study was performed evaluate the therapeutic and safety of tyndallized Lactobacillus rhamnosus (IDCC 3201, isolated from feces a Korean breastfed infant, repeated heat‐treated incubated, RHT3201) children Methods In randomized,...

We have evaluated prospectively the incidence and location of deep-vein thrombosis (DVT), risk factors for pulmonary embolism, natural history after total knee replacement (TKR) in patients who did not receive prophylactic or therapeutic treatment DVT. studied 227 underwent primary TKR; 116 had one-stage bilateral 111 unilateral procedures. Coagulation assays, full blood count typing tests serum chemical profile were undertaken all on three separate occasions. Bilateral simultaneous...

We have reviewed 70 patients with bilateral simultaneous total hip arthroplasties to determine the rate of failure and compare polyethylene wear osteolysis between an implant a cobalt-chrome head Hylamer liner that zirconia liner. The mean thickness was 11.0 mm (8.8 12.2) in 10.7 head. At follow-up at 6.4 years no acetabular or femoral component had been revised for aseptic loosening loose according radiological criteria both cemented cementless groups. linear annual were highest 22 (1.25...

A prospective study of 69 patients (138 knees) who had a primary simultaneous bilateral total knee replacement was conducted to assess the effect postoperative suction drainage on wound healing and infection. drain placed by randomization side for drained versus nondrained side. The same operative technique used in all wounds arthroplasty. knees that no drains higher incidence from wound, soaked dressings requiring dressing reinforcements, more ecchymosis erythema around wound. However,...

Although the design features of Medial Pivot fixed-bearing prosthesis reportedly improve kinematics compared with TKAs using fixed-bearings, clinical improvements have not been reported. We asked whether and radiographic outcomes, ranges motion knee, patient satisfaction, complication rates would be better in knees a than those PFC Sigma mobile-bearing prosthesis. results 92 patients who had implanted one knee other. There were 85 women seven men mean age 69.5 years (range, 55–81 years). The...

The major goals of revision total knee arthroplasty include good clinical and radiographic results with a low complication rate. A retrospective review case series arthroplasties constrained condylar prosthesis by single surgeon was performed in order to ascertain the role this determine whether it provided satisfactory results.Ninety-seven patients (114 knees) underwent use prosthesis. There were eighty-four men thirteen women. mean age at time index surgery sixty-five years. primary...

Background: The number of midterm or long-term studies on the current generation cementless total hip replacements with alumina-on-alumina ceramic bearings in patients younger than thirty years age is limited. purpose this study was to evaluate results metaphyseal fitting anatomic prosthesis age, a particular emphasis prevalence thigh pain, resorption bone due stress-shielding proximal part femur, aseptic loosening, and osteolysis. Methods: We reviewed cases ninety-six (127 hips) who had...

We have been using hybrid total hip arthroplasty (a cementless acetabular component and a cemented stem) in young patients. The purpose of this study was to determine the prevalence aseptic loosening, polyethylene wear, osteolysis after use technique.We studied prospective consecutive series sixty-four primary replacements fifty-five patients younger than fifty years old. There were forty-three men twelve women; average age at time index operation 43.4 years. duration follow-up 9.4 used...

A dark metallic-appearing smear, resembling a lead pencil mark, may be seen on ceramic femoral head component at revision total hip arthroplasty. The purpose of this study was to investigate the hypothesis that such mark retrieved is associated with increased surface roughness and polyethylene liner wear in replacement.Fifteen prosthetic heads from fifteen patients arthroplasty were examined study. Thirteen had been vivo for an average 10.8 years (range, 7.8 14.2 years). remaining two less...

A ceramic femoral head is an alternative to a metal for the bearing surface of total hip arthroplasty. The purpose this study was compare polyethylene wear in patients who had undergone bilateral arthroplasty with implants that differed only regard material used head: zirconia on one side, and cobalt-chromium inserted contralateral side.A prospective, randomized performed evaluate outcomes fifty-two sequential primary replacement. hip, other.
