Brief Summary: This multicenter, prospective cohort study will evaluate whether Robotic-Assisted total knee arthroplasty (RATKA) with a Medial Congruent implant is a successful method to improve implant alignment, insert thickness accuracy, and patient satisfaction, compared to a conventional TKA (cTKA) Medial Pivot technique. It aims to assess and compare clinical and functional outcomes in patients with severe knee osteoarthritis at 3, 6, and 12 months.
Detailed Description: This prospective, non-randomized, multicenter trial evaluates robotic-assisted (ROSA® Robotic Platform with Zimmer Biomet Persona® Medial Congruent) versus conventional (MicroPort Evolution® Medial-Pivot) total knee arthroplasty (TKA) in approximately 300 adults with severe osteoarthritis. By comparing robotic precision with a well-established Medial-Pivot design, this investigation aims to clarify whether robotic-assisted TKA confers superior implant positioning, reduced alignment outliers, and enhanced patient-reported outcomes (PROMS). The primary outcome measures include insert thickness, alignment accuracy (outliers defined as \>2° from the mechanical axis on full-leg radiographs), and patient satisfaction at 6 and 12 months. Two surgeons will perform both techniques, and one surgeon will perform only the conventional procedure. The 18-month study is conducted under local Institutional Review Board approvals (Medlife, Medicover, SCJU Cluj Napoca, Monza Bucuresti) and complies with GDPR. Results are intended for publication in a high-impact orthopedic journal. No external funding is provided.
