Öğe Are unilateral or staged bilateral total knee arthroplasty really safer than simultaneously bilateral TKA, or is it a myth?(ARSMB-KVBMG, 2018) Arslan, Aydin; Utkan, Ali; Ozkurt, BulentThe purpose is to evaluate feasibility of simultaneous TKA in comparison with staged and unilateral procedures. Number of patients included: 72 simultaneous bilateral, 61 staged bilateral and 222 unilateral TKAs were included. The mean age in the simultaneous group was lower than the other groups. Heart failure as comorbidity was observed less in the simultaneous TKA group than the other two groups. There was no significant difference between simultaneous and staged groups with respect to postoperative WOMAC and SF36 scores. Rates of thrombotic complications and mortality were not different. There was no significant difference in terms of wound healing, periprosthetic infection and TKA revision rates. Younger age and heart failure as a comorbidity were found to be decisive in the selection of simultaneous procedure. Thus, in the case of advanced bilateral knee osteoarthritis, simultaneous bilateral TKA should be performed after a proper preoperative risk assessment when there is a medical rationale, or the patient's personal preference. In the light of aforementioned conditions, hesitancy about simultaneous TKA seems unnecessary. © 2018, Acta Orthopaedica Belgica.Öğe External fixation versus hemiartroplasty in unstable intertrochanteric hip fractures of the elderly(Acta Medica Belgica, 2017) Polat, Metin; Arslan, Aydin; Utkan, AliTo compare two alternative methods : external fixation (EF) and hemiarthroplasty (HA) in elderly patients with unstable intertrochanteric hip fractures. Forty-two patients with Orthopaedic Trauma Association type 31A2-2 or 31A2-3 fractures treated between January 2007 and December 2010 were included. Twenty-two patients underwent hemiarthroplasty and twenty patients underwent external fixation. The mean length of stay in the operation room was 45 minutes and 108 minutes in the EF and HA groups, respectively (p< 0.05). The mean postoperative length of hospital stay was 2.7 days in the EF group and 4.9 days in the HA group (p< 0.05). The total length of hospital stay, functional scores and mortality rates were not different. Findings of the current study comparing EF and HA in a limited number of non-randomized elderly patients with unstable intertrochanteric fracture indicated that the EF method, when performed in a sufficiently stable manner, might be a valuable alternative to HA since it is less aggressive and cheaper.
