Oxidized zirconium femoral component for TKA: A follow-up note of a previous report at a minimum of 10years

Prospective comparative clinical study of ceramic and metallic femoral components for total knee arthroplasty over a five-year follow-up period

“…Since hypersensitivity reactions to metallic implant materials (e.g. chromium, cobalt and nickel) can cause implant failure, bioinert ceramic materials are a desirable alternative material for TKA [3,[7][8][9][10]. Today, ceramics are successfully used as an articulation partner in total hip arthroplasty, and may also be a promising and eligible material for TKA [3,[9][10][11][12].…”

“…The use of ceramics in TKA should not be expected to increase the functional outcome. However, by minimizing the generation of debris from wear, the use of the lowwear ceramic bearing may reduce osteolysis and implant loosening, and thus, provide better long-term survival of the total knee implants [9]. There is currently no clear clinical evidence that the use of ceramic femoral components would increase the survivorship of total knee replacement by reducing polyethylene wear.…”

Orthopaedic procedures in haemophilia

“…Total Knee Arthroplasty is one of the most common surgical procedures in haemophilic patients: it allows the correction of the malalignment and the reduction of the number of bleedings by the intra-operative synovectomy. Nowadays, by the use of modern modular knee systems, it is possible to restore bone loss with reconstructive devices (wedges, cones, offsets, stems, different choices of constraint) associated with the application of bone grafts (15,18,19). The hip is less frequently involved by haemophilic arthropathy, due to the paucity of the synovial tissue.…”

A comparative study of the mechanical behaviour of thermally oxidised commercially pure titanium and zirconium

“…Indeed, thermally oxidised Ti alloys have been reported to have the potential use in artificial hip joints (Yamamoto et al, 2009;Wang et al, 2014b;Lieblich et al, 2016), and thermally oxidized Zr has recently been introduced as an alternative bearing in total joint arthroplasty for artificial knee and hip joints (Patel and Spector, 1997;Good et al, 2005;Galetz et al, 2010;Innocenti et al, 2014). Thermally oxidised Ti and Zr possess the desirable combination of a ceramic bearing surface to resist wear and a tough metallic core to resist fracture Pawar et al, 2011;Alansari and Sun, 2017).…”
