Oxford Phase 3 unicompartmental knee arthroplasty: medium-term results of a minimally invasive surgical procedure

PURPOSE: In the last decade, a major increase in the use of and interest in unicompartmental knee arthroplasty (UKA) has developed. The Oxford Phase 3 UKA is implanted with a minimally invasive technique using newly developed instruments. The objective of this prospective study was to evaluate the outcome of UKA in patients with medial osteoarthritis of the knee in a high-volume unit. METHODS: Two-hundred and forty-four UKAs were performed with a minimally invasive approach. The median age was 72 (43-91) years. The median follow-up was 4.2 years (range 1-10.4 years). Fourteen patients died, and nine were considered to be lost to follow-up, but all had a well-functioning prosthesis in situ until their last follow-up. Pain, function and health-related quality of life were evaluated pre- and postoperatively using patient- and assessor-based outcome scores, as well as radiographic evidence. RESULTS: The mean Knee Society knee and function scores, WOMAC-scores, Oxford-score and VAS pain and satisfaction all improved. Nine knees required revision. Eleven patients required an additional arthroscopic procedure due to persisting pain secondary to intra-articular pathology, and four patients required manipulation under anaesthesia because of limited range of motion. The 7-year cumulative survival rate of the arthroplasty was 94.4%. A low incidence (21%) of a radiolucent line beneath the tibial component was observed at 5 years of follow-up. CONCLUSION: This study showed a high survival rate of the Oxford Phase 3 UKA. Patient satisfaction and functional performance were also very high. Major complication rate was low; in addition, the incidence of radiolucency under the tibial component, when compared to present literature, was low. When strict indication criteria are followed, excellent, durable, and in our opinion reliable, results can be expected for this procedur

Praktische aanbevelingen bij de aanpak van acute ritmestoornissen: Verslag van de Belgische Interdisciplinaire Werkgroep van Acute Cardiologie (BIWAC)

Acute arrhythmia is a condition covering a wide variety of rhythm disturbances. The aim of this article is to give practical recommendations for the management of the patient presenting with an acute arrhythmia. We discuss bradycardia and tachycardia. Tachycardias are divided into the small QRS complex tachycardias and the wide QRS complex tachycardias. Other important issues are the distinction between the hemodynamic stable and unstable patient and the need for trombo-embolic prevention of the patient with atrial fibrillation. Flowcharts with diagnostic means and therapeutic schemes as well as a table with practical considerations for electrical cardioversion are provided.SCOPUS: re.jinfo:eu-repo/semantics/publishe

Recommandations pratiques pour le traitement d'arythmies aiguës: Rapport du Groupe Interdisciplinaire Belge de Cardiologie Aiguë

Les arythmies aiguës comprennent une variété large de troubles du rythme. Les auteurs proposent des recommandations pratiques pour l’approche et le traitement du patient souffrant d’une arythmie aiguë. Ainsi sont discutées les brady-cardies et les tachycardies. Les tachycardies sont divisées en tachycardies à complexes QRS fins et celles à complexes larges. Par ailleurs, une importante distinction concernant la stabilité hémodynamique du patient est faite ; celle-ci va entraîner des conséquences thérapeutiques immédiates. Des arbres décisionnels clairs avec schémas diagnostiques et thérapeutiques des différentes arythmies sont proposés, de même que les considérations pratiques concernant la cardioversion électrique
