Eleven-Year Implant Survival Rates of the All-Polyethylene and Metal-Backed Modular Optetrak Posterior Stabilized Knee in Bilateral Simultaneous Cases

Tibial component designs in primary total knee arthroplasty: should we reconsider all-polyethylene component?

“…However, with recent modifications to their design, very acceptable results have been reported [9,30,46,47,49,50]. Many comparative studies have failed to show any difference between all-polyethylene and metal-backed tibial components [1-3, 6, 9, 16, 17, 50].…”

All-Polyethylene Versus Metal-Backed Tibial Components—An Analysis of 27,733 Cruciate-Retaining Total Knee Replacements from the Swedish Knee Arthroplasty Register

“…The all-polyethylene tibial component is less expensive than its modular counterpart 6 , and several randomized trials and smaller cohort studies have indicated that the allpolyethylene tibial component is at least equivalent to the modular design in function, knee motion, primary stability, and long-term implant survival [7][8][9][10][11][12] . These favorable findings also apply to patients with rheumatoid arthritis or obesity 13,14 .…”

Clinical and functional results of Optetrack™ Total Knee Arthroplasty after 6 to 13 years: findings from a retrospective study

“…Consequently, it is of fundamental importance to monitor over time the functional results of patients undergoing TKA implantation [5]. Numerous studies have been conducted over the years to observe the clinical and functional performance of this type of TKA [18][19][20][21][22][23]; this is useful for developing better and more durable prostheses over time and planning more appropriate rehabilitation interventions to achieve better functional recovery [13]. In Italy, a previous retrospective observational study assessed the clinical and functional results of 63 patients that underwent the same type of TKA Optetrack between 1999 and 2004 [24]; however, in this study, the maximum observation period was limited to 5 years.…”
