Objectives: As many patients with osteoporosis remain undiagnosed, we aimed to develop a simple method to efficiently screen for osteoporosis using a combination of anteroposterior hip X-ray assessment and the Osteoporosis Self-Assessment Tool for Asians (OSTA), which is calculated as (body weight - age) × 0.2.

Methods: One hundred Japanese women (age: 73 ± 11 years, body weight: 54.

Background: The risk of falls causing periprosthetic fracture has become an issue with the increase in the number of patients undergoing long-term follow-up after total hip arthroplasty (THA) and the aging of patients. The Timed Up and Go test (TUG) is utilized to evaluate fall risk. This study investigated muscle volume around the hip joint based on computed tomography (CT), CT value, and muscle strength to investigate contributing factors to poor TUG 1 year post-THA.

Background: A robotic arm-assisted and a computed tomography (CT)- based navigation system have been reported to improve the accuracy of component positioning in total hip arthroplasty (THA). However, no study has compared robotic arm-assisted THA (rTHA) to CT-based navigated THA (nTHA) concerning accuracy of cup placement and acetabular fractures using the direct anterior approach (DAA). This study aimed to compare the accuracy of cup placement and the presence of intraoperative acetabular fractures between rTHA and nTHA using DAA in the supine position.

Background: The aim of this study was to investigate the factors affecting patient-reported outcomes after bicruciate-stabilized total knee arthroplasty (BCS TKA) in patients.

Methods: We retrospectively examined 122 knees with primary varus knee osteoarthritis that underwent BCS TKA. This study analyzed preoperative, intraoperative, and postoperative predictors of patient satisfaction and persistent postsurgical pain following BCS TKA at 1 year after surgery.

Article Synopsis
  • Diagnosis and treatment of osteoporosis are crucial for successful hip surgery outcomes, and measuring bone mineral density (BMD) via DXA is the established method, but access can be limited.* -
  • The study analyzed 1378 female patients undergoing hip surgery, assessing the correlation between BMD and the Osteoporosis Self-assessment Tool for Asians (OSTA) score, finding a strong correlation and establishing a cut-off score that effectively predicts osteoporosis.* -
  • Results indicate that the OSTA tool can help screen for osteoporosis in at-risk patients before surgery, enabling targeted investigations and potentially improving patient outcomes.*
