Influencia del distrés psíquico prequirúrgico en los resultados de la cirugía protésica de rodilla

Résumé

The Knee Total Prosthesis (KTP) has been proved to be an efficient procedure when treating pain and physical disability [36, 170], improving the quality of life [80,139,117]. Aspects like mental health or the concept of distress have gained importance [60] in medical literature among the factors influencing the KTP results. The concept of distress comes from the distinction made by Hans Seyle (1974) between positive stress “eustres” and negative stress “distress”. When the response is adjusted to the needs provided by the stimulus or aggression, eustres or physiological adaptation occurs. On the contrary, if the response is insufficient, wrong or excessive, distress appears [150]. Many have been the instruments used to measure distress: HADS [33, 35], Brief Symptom Inventory [43], SCL-90 [42], GHQ [64, 105], Distress Thermometer [123] and MH Score (mental health subscale SF-36) [167]. The analysis of distress is difficult due to this huge variety of questionnaires for the study. In this project, HADS [173] was used to make psychic distress objective in situations of anxiety and depression. In order to assess the results of the KTP from a medical point of view, the Knee Society Score [5, 85, 92] was used, and the WOMAC [1, 5, 145, 15, 52, 58, 32, 121, 127, 28, 51, 135, 169], for the quality of life.
