Artroplastia do joelho navegada x mecânica: comparação entre casos iniciais de navegação e convencionais pelo mesmo cirurgião

“…In no case was there a need to deflate the tourniquet until cementation of the implants. These findings are concordant with the descriptions by Albuquerque (1) , Bäthis et al (4) and Cheung and Chiu (9) , who stated that the increase duration of the procedure did not have any decisive influence on the final result. However, it is worth emphasizing that a good team is required for performing this technique.…”

“…The success of the surgical procedure depends on several factors, such as patient selection, prosthesis design, ligament balance and restoration of the knee joint line and lower-limb alignment (1)(2)(3)(4)(5)(6)(7)(8) . Restoration of limb alignment is believed to be one of the principal factors enabling good long-term results, both clinically and functionally.…”

“…Comparisons between navigated surgery and the conventional method (4,6,9,(15)(16)(17) have demonstrated that computer-assisted surgery may provide better alignment in the coronal and sagittal planes (less than three degrees from neutral alignment), since it helps the surgeon to determine the alignment throughout (1,4,9) .…”

Navigated Versus Mechanical Knee Replacement: Comparison Between Initial Navigated and Conventional Cases Performed by the Same Surgeon

“…Total arthroplasty is greatly used in cases of advanced osteoarthrosis of the knee with the aims of eliminating painful symptoms, correcting deformities and stabilizing the joint. The success of the surgical procedure depends on several factors, such as patient selection, prosthesis design, ligament balance and restoration of the knee joint line and lower-limb alignment 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 .…”

“…Over recent years, computer-assisted surgical systems have contributed towards surgical precision. According to Albuquerque et al 1 , 14 , the main contribution of such systems is precision in implanting prostheses and aligning the mechanical axis of the operated limb. Furthermore, such procedures are little more invasive; they diminish or eliminate exposure to radiation; and the instruments used are the same as used in mechanical procedures.…”
