Grande parte das publicações aborda somente os aspectos técnicos e o desempenho dos implantes e negligencia a repercussão sobre a qualidade de vida e as co-morbidades, tornando a medida correta dos benefícios do tratamento imprecisa. Atualmente, os parâmetros de medição da qualidade de vida associados às escalas funcionais tornaram-se imperativos para uma análise acurada de resultados e fatores influentes. O objetivo principal do estudo foi avaliar a qualidade de vida relacionada à saúde em pacientes afetados por osteoartrose do quadril e tratados por artroplastia total do quadril. Estudou-se prospectivamente uma coorte de 38 pacientes operados em hospital universitário de referência regional acompanhados durante, no mínimo, seis meses até atingirem reabilitação satisfatória. Secundáriamente, avaliou-se o desempenho de curto prazo do componente acetabular MD4® implantado em 35 indivíduos. Os dados foram obtidos por meio da aplicação de quatro instrumentos: 1) questionário para a caracterização sóciodemográfica e clínica da amostra; 2) escala de avaliação funcional do quadril – Harris Hip Score (HHS); 3) instrumento genérico de avaliação da qualidade de vida relacionada à saúde The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) e 4) questionário de avaliação da satisfação individual com o procedimento. Os resultados dos testes pré e pós-operatórios foram submetidos à análise estatística descritiva e comparados com a literatura. Os resultados pré e pósoperatórios do SF-36 foram capacidade funcional: 13,4-53,7; limitação por aspectos físicos: 9,21-48,0; dor: 23,1-62,6; estado geral de saúde: 54,2-71,3; vitalidade: 40,3- 69,9; aspectos sociais: 40,8-74,3; limitação por aspectos emocionais: 23,7-64,9; saúde mental: 52,6-80,4. O Harris Hip Score variou de 36,1 a 92,1, em média. Todos os resultados foram estatisticamente significantes (p < 0,001). A combinação de duas escalas mostrou-se valiosa na identificação de vieses e conferiu maior confiabilidade na compreensão das diversas variáveis. O estudo demonstra uma significativa melhora na qualidade de vida relacionada à saúde em pacientes afetados por osteoartrose de diferentes etiologias submetidos à artroplastia total do quadril. A avaliação da qualidade de vida não substitui a avaliação clínica provida por instrumentos específicos e pela experiência do cirurgião, mas pode adicionar dados importantes ao valorizar o conjunto de expectativas do paciente perante um tratamento médico e ser considerada um instrumento eficiente na análise de resultados da artroplastia total do quadril. Adicionalmente, o componente acetabular avaliado mostrou estabilidade e indícios de osteointegração em todos os casos, o que pode ser considerado indicativo de bom desempenho a médio prazo do implante. / Total hip replacement is one of the most cost-effective procedures upon the locomotor system. Most of the publications covers only the technical aspects and the performance of implants and neglects the impact on the quality of life and comorbidities, making the correct measurement of a treatment benefits imprecise. Nowadays, the measurement of health-related quality of life associated with functional scales has become imperative for more accurate analysis of results and influencing factors. To assess the health – related quality of life in patients with osteoarthritis and undergoing total hip arthroplasty was the main goal in this study. A cohort of 38 patients from a regional referral teaching hospital was prospectively followed up for at least six months until they have achieved satisfactory rehabilitation. Secondarily, the short-term performance of the MD-4® acetabular component implanted in 35 individuals was evaluated. Data were obtained through the application of four instruments: 1) questionnaire for socio-demographic and clinical characteristics of the sample; 2) functional scale of the hip - Harris Hip Score (HHS); 3) generic instrument for assessing health-related quality of life The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and 4) questionnaire assessing individual satisfaction with the procedure. The results pre and postoperatively were analyzed using descriptive statistics and compared with the literature. The SF-36 results pre and post-operative were functional capacity: 13.4 to 53.7, limited by physical aspects: 9.21 to 48.0; pain: 23.1 to 62.6, general health: 54.2 to 71.3; vitality: 40.3 to 69.9; social aspects: from 40.8 to 74.3, limited by emotional aspects: from 23.7 to 64.9; mental health: 52.6 - 80.4. The Harris Hip Score ranged from 36.1 to 92.1 on average. All results were statistically significant (p < 0.001). The combination of two scales showed up to be valuable in bias identification and gave more reliability on the variables understanding. The study reports a significant improvement in health-related quality of life in patients affected by osteoarthritis of many etiologies that underwent total hip replacement. Healthrelated quality of life assessment does not replace clinical evaluation provided by specific instruments and the physician’s experience but can add important data and also can be considered an efficient tool in analyzing outcomes of total hip replacement due to the weight it gives to the patient’s expectations regarding a medical treatment.Additionally , the study showed up evidence of osteointegration and stability of the acetabular cup in all cases, which would be a predictor factor for mid-term survivorship of this acetabular component.

Abstract Knee osteoarthritis (OA) is one of the main causes of chronic disability in elderly people. In end-stage knee OA, patients experience both short- and long-term benefits from total knee arthroplasty (TKA). All the significant deficiencies in functional capacity and health-related quality of life (HRQOL) are not spontaneously resolved after surgery. Therefore, it is essential that patients receive effective rehabilitation. So far, there are no gold standards in terms of outcome measurements of TKA and rehabilitation in connection with surgery. The present series of studies was designed for the purpose of examining the effectiveness and cost-effectiveness of a multidisciplinary rehabilitation program compared with conventional orthopedic care, the attributes of disability in elderly knee OA patients waiting for primary TKA, and the impact of patient-relevant factors on the outcome of TKA one year after surgery. Special emphasis was placed on self-reported functional capacity, HRQOL, and objectively measured functional capacity. Objective and subjective physical function and HRQOL were investigated with a battery of physical function tests and questionnaires (WOMAC, 15D, and RAND-36) during a one-year follow-up. Pain, body mass index (BMI), and antero-posterior laxity of the affected knee were the main attributes of self-reported disability in the patients waiting for primary TKA. The multidisciplinary rehabilitation program did not yield faster attainment of recovery than did conventional orthopedic care. Equal, significant improvement in HRQOL and functional capacity was found in both groups, but conventional care was clearly cost-saving. A preoperative score below the general population level on the 15D, the presence of pain, higher age, and the presence of pulmonary disease preoperatively decreased the possibility of reaching the HRQOL level of the general population. More severe pain preoperatively was associated with a higher degree of functional recovery. The presence of osteoporosis, male gender, impaired function of the opposite knee, and higher age were associated with a lower degree of improvement in self-reported function. The results highlight the multifactorial nature of health status in TKA. Further intervention studies are needed to identify patients who would benefit most from intensive rehabilitation interventions after TKA and to create standards for outcome tools after joint replacement surgery and rehabilitation interventions. / Tiivistelmä Polvinivelrikko on merkittävimpiä niistä sairauksista, jotka rajoittavat ikääntyneiden toimintakykyä. Vaikka tekonivelleikkauksella voidaan sekä välittömästi että pidemmän ajan kuluessa kohentaa merkittävästi polvinivelrikosta kärsivien elämänlaatua ja toimintakykyä, osa potilaista ei leikkauksen jälkeenkään selviydy hyvin arjestaan. Siksi on tärkeää, että potilasta kuntoutetaan tekonivelleikkauksen jälkeen asianmukaisesti ja tehokkaasti. Leikkauksen ja kuntoutuksen tuloksellisuutta arvioivien mittareiden käytöstä ei ole olemassa standardoituja suosituksia. Tämän väitöskirjan päätavoitteena oli selvittää 2–4 kuukautta leikkauksen jälkeen toteutetun, moniammatillisen, polikliinisen kuntoutuksen kustannustehokkuutta sekä sen vaikuttavuutta elämänlaatuun ja toimintakykyyn verrattuna perinteiseen ortopediseen hoitokäytäntöön. Lisäksi selvitettiin tekijöitä, jotka heikentävät potilaan toimintakykyä pitkälle edenneessä polvinivelrikossa, sekä potilaslähtöisiä tekijöitä, jotka vaikuttavat leikkaustulokseen vuosi leikkauksen jälkeen. Itsearvioitua toimintakykyä sekä elämänlaatua arvioitiin kyselykaavakkeiden (WOMAC, 15D ja RAND-36) avulla ja fyysistä toimintakykyä mitattiin testipatteristolla. Tutkimuksen seuranta-aika oli yksi vuosi. Painoindeksi, kipu ja leikattavan polven etu-takasuuntainen väljyys selittivät eniten tekonivelleikkausta odottavien potilaiden toimintakyvyn rajoitteita. Potilaiden elämänlaatu ja toimintakyky kohenivat merkittävästi tekonivelleikkauksen jälkeen. Moniammatillisesti toteutettu kuntoutus ei tehostanut leikkauksesta toipumista verrattaessa sitä perinteiseen ortopediseen hoitokäytäntöön, joka vertailussa myös säästi selkeästi kustannuksia. Väestökeskiarvoa huonommaksi koettu elämänlaatu jo ennen leikkausta, kivuliaisuus, korkea ikä ja keuhkosairaudet heikensivät mahdollisuutta saavuttaa väestökeskiarvon tasoinen koettu elämänlaatu vuosi leikkauksen jälkeen. Leikkausta edeltävä vaikea-asteinen kivuliaisuus assosioitui merkittävään toimintakyvyn parantumiseen. Osteoporoosi, miessukupuoli, vastakkaisen polvinivelen epänormaali toiminta ja korkea ikä taas liittyivät vaatimattomampana koettuun toimintakyvyn parantumiseen. Tekonivelleikattujen potilaiden terveydentilan monitekijäisyys heijastuu tutkimustuloksiin. Jatkossa tarvitaan interventiotutkimuksia, jotta voitaisiin paremmin tunnistaa ne potilaat, jotka hyötyisivät eniten tehostetusta leikkauksen jälkeisestä kuntoutuksesta. Lisäksi olisi tärkeää tutkia, miten kuntoutuksen tuloksellisuutta arvioivia mittareita voitaisiin yhtenäistää.
