� Purpose:We previously reported results of a mean 3.2-year follow-up of the COREN hip system, which is the first total hip prosthesis developed in Korea. The aim of this prospective study was to update the previous report with regard to the hip function and radiographic implant performance. Materials and Methods: Between 2003 and 2004, a consecutive series of 68 primary, cementless, total hip prostheses (COREN) were implanted in 57 patients(68 hips) and followed up for a minimum of 7 years. Sixtythree of the 68 hips were available for clinical scoring and radiographic analysis. Results: The mean Harris hip and WOMAC scores were improved from 48.1 and 54.7, preoperatively, to 96.4 and 22.1 at the final follow-up. The mean patient activity increased from 3.1, preoperatively, to 8.2 at the final follow-up. All hips showed stable bony ingrowth on the radiographs. No hips showed evidence of osteolysis or prosthesis loosening, and no revision was required during the follow-up. A Periprosthetic fracture (Vancouver type B1) was encountered in one hip 4.7 years after surgery, which was treated by reoperation. Conclusion: This study shows that the COREN hip system produces excellent mid-term results in cementless hip arthroplasty.

“…Radiographic analysis was performed by a blinded observer on 6-week and 1-year postoperative, standardized, AP pelvis radiographs using a Picture Archiving and Communications System Software (Synapse 1 ; Fujifilm Medical System, Stamford, CT, USA). Anteversion and inclination of the acetabular cup were assessed as previously described by Liaw et al [16], femoral stem alignment was determined as per Ellison et al [11], hip offset was measured as described by Dastane et al [8], and limb length difference was assessed as described by Ranawat et al [29]. Osseointegration of components was assessed based on absence of radiolucent lines and implant migration or subsidence.…”

Background Newer surgical approaches to THA, such as the direct anterior approach, may influence a patient's time to recovery, but it is important to make sure that these approaches do not compromise reconstructive safety or accuracy. Questions/purposes We compared the direct anterior approach and conventional posterior approach in terms of (1) recovery of hip function after primary THA, (2) general health outcomes, (3) operative time and surgical complications, and (4) accuracy of component placement. Methods In this prospective, comparative, nonrandomized study of 120 patients (60 direct anterior THA, 60 posterior THAs), we assessed functional recovery using the VAS pain score, timed up and go (TUG) test, motor component of the Functional Independence Measure TM

“…In conclusion, correct position in the acetabulum requires restoration of the COR within 3 mm superior and 5 mm medial for both cup longevity [18] and ease of restoration of offset and leg length [19]; inclination that allows clearance of the femoral head in sitting without impingement according to the spine-pelvic motion [2][3][4]; and combined anteversion of the stem and cup that allows the femoral head to remain centered in the cup throughout the arc of motion [4,11,12].…”
