Mid-term results of Oxford Phase 3 unicompartmental knee arthroplasty in obese patients

Abstract

Oxford Phase 3 UKA with mobile bearing has good mid-term results in obese patients over 60 years of age.

The long-term results of cemented Oxford unicompartmental knee arthroplasty: A single-center experience

“…They found no complications during this time period except three insert dislocations. [12] The reported results of these studies are consistent with the early-and mid-term results reported by the Oxford designer surgeons. On the other hand, our findings are consistent with the studies using the registry data of England, Sweden, and Finland, suggesting that long-term follow-up studies with larger sample sizes are more reliable.…”

“…Several studies on Oxford UKA have also been conducted in Turkey, reporting successful short-and mid-term clinical results. [10][11][12] For example, Aslan et al, [10] conducted a 28-month follow-up study on cemented Oxford UKA in 27 patients in 2007 and reported that only two (7.4%) patients required revision surgery due to tibial collapse. Furthermore, in 2010, Parmaksızoğlu et al [11] reported the outcomes of 38 cases of cemented Oxford UKA for 24-month follow-up.…”

“…They reported excellent outcomes with no patients having any complications. [11] In another study, Cepni et al, [12] reported the outcomes of 67 patients with obesity (body mass index >30) in 2014 for a mean of 67.5-month follow-up. They found no complications during this time period except three insert dislocations.…”

“…[6][7][8][9] Several studies have also been performed in Turkey, reporting successful short-and mid-term clinical outcomes of Oxford UKA. [10,12] However, the presence of controversial data reported in the literature encouraged us to investigate the longterm clinical outcomes of Oxford UKA with a large number of cases which could potentially contribute to the controversial notion of UKA in the literature. Accordingly, in this study, we aimed to investigate the long-term clinical outcomes, complications and survival rates of cemented Oxford medial UKA and to compare the findings with the reported outcomes of UKA and TKA in the literature.…”

Indikationen und Grenzindikationen zum medialen unikondylären Gelenkersatz mit mobiler Inlay-Komponente

“…In einer Studie von Murray et al anhand von 2438 Patienten nach medialen OUKR konnte kein Zusammenhang im klinischen funktionellen Outcome oder der Versagerrate mit dem Body-Mass-Index festgestellt werden [44]. Ähnliche Ergebnisse konnten in weiteren Studien bestätigt werden [43,45,46]. Ebenso konnte anhand ausgebauter Polyäthylen-Inlays kein Einfluss auf die lineare Abriebrate des Polyäthylens durch Übergewicht festgestellt werden [6], weshalb eine Gewichtsgrenze in den Selektionskriterien für die Oxford-Schlittenprothese nicht enthalten ist [16,44].…”
