PERSEUS is a cutting guide for Knee Arthroplasty designed to achieve optimal bone resections with less effort and comorbidity respect to conventional instrumentation. Proper alignment of the prosthesis during knee replacement is critical in maximizing implant survival[6] and to reduce polyethylene wear[1]. Poor overall anatomic alignment of a total knee replacement is associated with a 6.9 times greater risk of failure due to tibial collapse, that varus tibial alignment is associated with a 3.2 times greater risk[2] and valgus femoral alignment is associated with a 5.1 times greater risk of failure[6]....

Advantages for surgeons PERSEUS ensures: • Accurate bone mechanical axis detection • Precise slope and varus-valgus cutting guide positioning for optimal bone resection • Real-time feedback about resection orientation • Intraoperative results validation • Post operative surgical report in PDF More confidence, more safety • Avoid risks related to intramedullary nail • Same precision as navigation system, but less cumbersome and easier to use • Increased confidence in surgical decisions • Reduced surgical operating time • Reduced blood loss compared to IM instruments [7] • Reduced cost and complexity...
