Fluoroscopy Computer Navigation Versus Manual Fluoroscopic Acetabular Positioning in Direct Anterior Total Hip Arthroplasty: Safe Zone Compliance and Learning Curve Analysis

Background Fluoroscopy is commonly leveraged in direct anterior approach total hip arthroplasty (DAA-THA). Computer-navigation systems provide real-time guidance aiming to enhance component positioning, but their learning curves and component accuracy remains incompletely charact...

PARTIAL POSTERIOR CRUCIATE LIGAMENT RELEASE IN TOTAL KNEE ARTHROPLASTY MITIGATES EXCESSIVE ROLLBACK WITHOUT COMPROMISING IMPLANT FIXATION

Introduction Balancing the posterior cruciate ligament (PCL) remains challenging in total knee arthroplasty (TKA). Excessively tight PCL can limit range of motion, cause excessive femoral rollback, and induce anterior implant liftoff. While selectively releasing a tight PCL can r...
