Bicruciate retaining total knee arthroplasty : results throughout history / Jef De Mulder in Acta Orthopaedica Belgica, Vol.87/1 (Mars 2021)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.87/1 (Mars 2021) . - p. 73-83 Titre : Bicruciate retaining total knee arthroplasty : results throughout history Type de document : texte imprimé Auteurs : Jef De Mulder ; Pieter Berger ; Hilde Vandenneucker Année de publication : 2021 Article en page(s) : p. 73-83 Note générale : https://doi.org/10.52628/87.1.10 Langues : Anglais (eng) Mots-clés : Bicruciate retaining  total knee arthroplasty  Vanguard XP Résumé : Approximately 20% amongst patients are dissatisfied after total knee arthroplasty (TKA). Bicruciate retaining (BCR) TKA offers superior knee kinematics and proprioception, but many surgeons abandoned its use because of complications and technical difficulties. Recently, two new BCR implant designs were introduced : Vanguard XP (Zimmer Biomet) and Journey XR (Smith&Nephew). We searched Pubmed, Limo, Embase and Cochrane, screened reference lists of eligible studies and included studies that met the inclusion criteria. We included 35 articles reporting on ten different BCR implants, including three articles presenting results of the Vanguard XP prosthesis. Unfortunately, no articles reporting on the results of the Journey XR prosthesis had been published. The BCR implants of the early 1970s showed good functional results, but a high rate of complications, mainly loosening and infections. The Townley Anatomic TKA was the first BCR implant with good clinical results, a low incidence of loosening and a high survivorship. One article of the three reporting on the Vanguard XP yielded high patient satisfaction (94%) with two revisions (1.4%). The two other articles reported three revisions (5%) after one year of follow-up and 19 revisions (13.4%) after three years of follow-up. Throughout history, the functional results of BCR TKA improved, with lessening of the complications. The short-term results of the Vanguard XP implant showed good functional results, but two out of three articles reported a high rate of loosening. Based on the results reported in this review, the use of BCR TKA is still debatable. Further high-level evidence research is necessary to assess the clinical benefit of BCR TKA.

Metal wear debris generation in primary total knee arthroplasty / Jonas Kellens in Acta Orthopaedica Belgica, Vol. 87/4 (Décembre 2021)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol. 87/4 (Décembre 2021) . - p. 681-695 Titre : Metal wear debris generation in primary total knee arthroplasty : is it an issue? Type de document : texte imprimé Auteurs : Jonas Kellens ; Pieter Berger ; Hilde Vandenneucker Année de publication : 2021 Article en page(s) : p. 681-695 Note générale : https://doi.org/10.52628/87.4.13 Langues : Anglais (eng) Mots-clés : knee  prosthesis  arthroplasty  metal  adverseeffects Résumé : More durable total knee arthroplasties (TKAs) are needed, due to the rising life expectancy, the higher activity levels of patients and the growing concerns about aseptic loosening being caused by metal hypersensitivity. In response, different hypoallergenic metal coatings have been developed for TKAs. How- ever, possible adverse effects of these different metals (cobalt-chromium-molybdenum, zirconium, titanium and tantalum) have been neglected. The aim was to summarize the local and systemic adverse effects (including metal hypersensitivity), survival ratios, patient-reported outcome measures (PROMs) and the plasma metal ion concentrations of the different TKA coatings. A literature search on PubMed and EMBASE was performed. In total, 15 studies were found eligible. Common adverse effects of TKA were infection, loosening, pain, instability and hyper- coagulation disorders. Serious adverse effects related to TKA implants were not reported. The survival ratios and patient-reported outcome measures seem to confirm these good results. In contrast with chromium and cobalt, no significant differences were reported in the nickel, molybdenum and titanium concentrations. No significant differences between the hypoallergenic and standard TKA implants were found in terms of adverse effects, survival ratios and PROMs. A causal relationship between the common adverse effects and the different metals is unlikely. Due to the heterogeneity of the TKA implants used, no firm conclusions could be made. Further research with longer follow-up studies are needed to find possible adverse effects and differences. Thus far, the hypoallergenic implants seem to perform equal to the standard implants.
