Resultados de revisão de artroplastia total do joelho com haste não cimentada "Press-fit"

Abstract

OBJECTIVE: To show our experience with press-fit cementless stem and metaphyseal fixation with cement in a selected series of patients who underwent revision total knee arthroplasty. METHODS: Thirty-four patients (35 knees) underwent revision total knee arthroplasty using the press-fit technique. Minimum follow-up was one year (mean 2.2 years) with a maximum length of three years. RESULTS: Of 34 patients, 20 were women and 14 were men. There was one death due to causes not related to arthroplasty and one patient dropout. There were no cases in which further review was necessary. Patients who underwent revision had clinical and functional improvement demonstrated by the results of the KSS, results of the SF-36 quality of life questionnaire, through gains in range of motion and improved limb alignment. CONCLUSION: There was postoperative clinical and functional improvement in comparison to the preoperative status in revision total knee arthroplasty with press-fit cementless stem. Level of Evidence IV, Case series.

Fixation of stem in revision of total knee arthroplasty: cemented versus cementless—a meta-analysis

“…Some studies reported good long‐term results of cemented stems with proposed advantages of excellent initial stability, less micro‐motion and increased flexibility of implant placement [15, 32]. Whiles others argued that a diaphyseal engaging cementless stem would avoid stress shielding around this area and facilitate probable component removal during rerevision [6, 12, 15, 23, 34, 48]. It revealed in the present study comparable mid‐ to long‐term clinical and radiographical outcomes of both fixation techniques.…”

“…Certain guidelines and proposal regarding meta‐analyses of observational studies were followed to suppress inherent bias in study designs [34, 47]. Studies without clarification of complications of special interventions were excluded during qualitative synthesis [13, 23, 25] (Fig. 1).…”
