About

Daniel H. Wiznia is an orthopedic surgeon and researcher whose work sits at the intersection of joint replacement innovation and surgical technology. Specializing in total hip arthroplasty (THA) and total knee arthroplasty (TKA), Wiznia has made significant contributions to optimizing surgical techniques, implant positioning, and the integration of computer-assisted and robotic technologies in complex joint replacement procedures. His most cited work, "Techniques for Optimizing Acetabular Component Positioning in Total Hip Arthroplasty" (2019, 18 citations), underscores his commitment to precision in preoperative planning, addressing critical factors such as anteversion, inclination, and limb length. This focus on planning extends into his exploration of robotic-assisted TKA, where his research highlights tangible clinical benefits including improved mechanical axis restoration and faster patient recovery. Particularly forward-thinking is Wiznia's application of 3D computer simulation to model real-world patient movements—including daily activities beyond standard functional positions—to better predict and prevent postoperative complications like impingement and dislocation. His investigations into prosthetic range of motion, offset restoration, and component sizing reflect a rigorous, data-driven approach to surgical decision-making. Collectively, his body of work is shaping how surgeons plan and execute joint replacements with greater accuracy and patient-centered outcomes.
