The purpose of this study is to evaluate the midterm results of cementless revision total hip arthroplasty (THA) using Wagner Cone Prosthesis. Between 1996 and 2007, 36 hips in 36 consecutive patients underwent femoral revision THA using Wagner Cone Prosthesis. Among them 28 hips were followed for more than 5 years. The mean age at revision surgery was 57 years and a mean follow-up was 7.6 years. The Paprosky classification system was used for preoperative bone loss evaluation. Clinical results were evaluated using Harris hip scores. For evaluation of the femoral component, radiolucent lines at bone-implant interfaces were evaluated and femoral component vertical subsidence was measured. Heterotopic bone formation and complications were also evaluated.Purpose
Material and Methods
The purpose of this study was to evaluate the results of two stage reconstruction for infected arthroplasty of hip joint and to know the risk factor for failures. From May 2004 to September 2011, 104 consecutive patients (105 hips) who underwent two stage reconstruction for the infected arthroplasty of hip joint were retrospectively evaluated. There were 60 hips with primary THA infection (Acute infection 22, Delayed infection 38), 4 hips with revision THA infection (Acute infection 1, Delayed infection 3), 20 hips with primary hemiarthroplasty infection (Acute infection 14, Delayed infection 6) and 24 hips with acute pyogenic coxitis. We evaluated the number of surgeries before two-stage reconstruction and also analysed the cultured pathogens. Mean follow duration after 2nd stage revision THA was 1.80 ± 1.76 years and average age at the time of 1st stage surgery (Debridement and PROSTALAC insertion) was 62.8 ± 14.3 years.Purpose:
Patients and Methods:
One of advantages of single-radius femoral design was to offer better ligament stability based on a maintained isometry of extensor muslce during the whole range of motion. The purpose of this study was to compare intraoperative varus-valgus laxities from 0° to 90° of flexion in patients that received TKA using either a single-radius femoral design or multiradius femoral design. 56 TKAs with a single-radius femoral design (SR group) and 59 TKAs with multiradius femoral design (MR group) were included in this study. We measured and compared varus-valgus laxities at 0°, 30°, 60°, 90° of flexion using the navigation system and manual force between the 2 groups.Background
Methods
We analyzed a consecutive series of 36 total hip arthroplasties using cementless conical stem with a shortening osteotomy combined with greater trochanter transfer in cases with a high dislocated hip. The causes of total hip arthroplasty were the sequelae of a septic hip in 20 cases and developmental dysplasia of the hip (DDH) in 16 cases. Mean patient age was 43.4 and the mean follow-up period was 3.3 years. We compared perioperative parameters, clinical, radiological results and complications between the two groups.Purpose
Material and Methods
Bilateral simultaneous and staged total hip arthroplasty has been issues in terms of safety and costs with development of surgical technique, postoperative medical care. The purpose of this prospective study is to compare the outcomes of simultaneous and staged bilateral operations, in terms of outcome, safety, and socioeconomic-effectiveness. All patients(470 cases) that underwent simultaneous or staged bilateral THA using modified minimally invasive two-incision technique between January 2004 and November 2009 were registered, and after exclusion divided into two groups; simultaneous bilateral THA group (Group A: 171 patients) and staged bilateral THA group (Group B: 64 patients) by patient's condition and preference. Staged operations were performed at the time when patients want to get surgery due to undurable pain. For clinical evaluations, amounts of blood loss, blood transfusion, postoperative morbidity and mortality were compared. And for socioeconomic-effectiveness, costs for hospitalization and time for returning to previous job were investigated.Purpose
