AbstractResume Objectif Developper un instrument de qualite de vie (QV) specifique de l'arthrose du genou et de la hanche (AMIQUAL) et etudier sa validite et sa reproductibilite. Methodes Soixante-dix-neuf patients et 28 professionnels de la sante ont participe a des entretiens individuels ou de groupe. L'analyse de contenu des entretiens a permis d'extraire une liste de 80 items potentiels. Quarante-six de ces 80 items ont ete selectionnes sur leur contenu pour former la version 1.0 de l'AMIQUAL. Les proprietes psychometriques de l'instrument ont ete etudiees chez des patients suivis pour coxarthrose ou gonarthrose definies selon les criteres d'Altman. Resultats L'analyse psychometrique de l'AMIQUAL (1.0) complete par 263 patients a permis d'exclure trois items supplementaires pour aboutir a une version 2.3 du questionnaire. L'analyse en composantes principales a identifie quatre facteurs : « Activites Physiques », « Sante Mentale », « Activites Sociales » et « Soutien Social ». Une dimension « Douleur » a secondairement ete individualisee. L'analyse des dimensions a montre que la reproductibilite, la validite de construction et les capacites discriminantes de l'instrument etaient satisfaisantes. Les reponses moyennes standardisees etaient proches de 1 pour les dimensions « Douleur » et « Activites Physiques » et de 0,7 pour la dimension « Sante Mentale » temoignant d'une bonne validite longitudinale apres mise en place d'une prothese. Conclusions L'AMIQUAL est le premier instrument de QV specifique de l'arthrose des membres inferieurs. Il est capable de capturer les aspects specifiques de la QV des patients et possede les proprietes psychometriques requises pour etre utilise dans des etudes longitudinales.

TL;DR: A semantically equivalent translation has been developed with cultural adaptation of OAKHQoL and it is quite reliable and a valid measure of the effect of osteoarthritis on the quality of life on Moroccan patients.
Abstract: The aim of this study was to adapt the knee and hip osteoarthritis quality of life questionnaire (OAKHQoL) into Moroccan Arabic and to determine its psychometric properties. After translation, back-translation and pretesting, the translated version was submitted to an expert committee. The psychometric properties were tested on patients with hip or knee osteoarthritis. Internal consistency was tested using Cronbach’s alpha coefficient (α), and the test–retest reliability using intraclass correlation coefficients (ICC). Construct validity was assessed by examining item-convergent and divergent validity and by comparing the average scores between age groups and walk perimeter groups. The study was conducted on 131 patients (115 with osteoarthritis of the knee and 16 with osteoarthritis of the hip). The “physical activities” (α = 0.93), “mental health” (α = 0.84) and “pain” (α = 0.88) dimensions of the Arabic version were internally reliable. The ICC were adequate to good; 0.83 for “physical activities”, 0.65 for “mental health” and 0.70 for “pain” dimensions. The instrument demonstrated good construct validity; all items exceeded the 0.4 criterion for convergent validity, except items 13 and 41 and most of the correlations between items and their own scale were significantly higher than their correlations with other scales. A semantically equivalent translation has been developed with cultural adaptation of OAKHQoL. It is quite reliable and a valid measure of the effect of osteoarthritis on the quality of life on Moroccan patients.

TL;DR: An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability.
Abstract: In clinical measurement comparison of a new measurement technique with an established one is often needed to see whether they agree sufficiently for the new to replace the old. Such investigations are often analysed inappropriately, notably by using correlation coefficients. The use of correlation is misleading. An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability.

TL;DR: WOMAC is a disease-specific purpose built high performance instrument for evaluative research in osteoarthritis clinical trials and fulfil conventional criteria for face, content and construct validity, reliability, responsiveness and relative efficiency.
Abstract: Within the context of a double blind randomized controlled parallel trial of 2 nonsteroidal antiinflammatory drugs, we validated WOMAC, a new multidimensional, self-administered health status instrument for patients with osteoarthritis of the hip or knee. The pain, stiffness and physical function subscales fulfil conventional criteria for face, content and construct validity, reliability, responsiveness and relative efficiency. WOMAC is a disease-specific purpose built high performance instrument for evaluative research in osteoarthritis clinical trials.

TL;DR: Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes and these proposed criteria utilize classification trees, or algorithms.
Abstract: For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or para-articular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.

Abstract: An end-result analysis is presented of thirty-nine mold arthroplasties performed at the Massachusetts General Hospital between 1945 and 1965 in thirty-eight consecutive private patients for arthritis of the hip following fractures of the acetabulum or dislocations of the hip. Of the nineteen unilateral cases in the second half of the series, sixteen were rated good or excellent. Results in the second half of the series were significantly better statistically than those in the first half of the series. Possible reasons for this improvement are discussed. No significant deterioration occurred with the passage of time. Among the thirty-nine hips, three revisions were required. One patient had postoperative sepsis after arthroplasty. Four patients who had had intra-articular sepsis prior to arthroplasty showed no evidence of sepsis postoperatively. Factors influencing the choice between hip fusion and hip arthroplasty in these cases are presented. A new system for rating hip function is proposed and is compared with the systems of Larson and Shepherd.
