During the development the patients were used as experts and generated questions with content that is important for them. FJS-12 was tested postoperatively and is primarily used postoperatively beyond 6 months. Therefore, the items may not be representative for all periods of the pre- and postoperative phase and may not rep- resent the patients experience with getting an artificial joint. Purpose / Aim of Study: We performed focus group interviews with patients to evaluate if the FJS-12 contains relevant items preoperatively, and postoperatively at 3 and 12 months after THA. Materials and Methods: Patients with primary osteoarthrosis, receiving a THA aged 60-75 years, were recruited for focus group interviews from Two Danish hos- pitals. We recruited seven patients preoperatively, nine patients at three months postoperatively, and twelve patients at twelve months postoperatively, totaling 28 patients. Findings / Results: By comparing the items identified in the interviews with items from FJS-12, we showed that all items from the FJS-12 is mentioned in one or more time periods. Sleeping, housework or gardening, and favorite sport were very important items in all three time periods. Three items were identified as being very important by the patients in all three time periods and were not covered by the FJS- 12: walking, pain in general, and reaching down/getting up from the floor. Walking was a very important item for patients in all time periods. Conclusions: We showed that the FJS-12 contain items relevant to the present- day patients both pre- and post- operatively. Some additional categories to the FJS- 12 were identified, mainly pain and reaching down/getting up from the floor. Because walking is mentioned in two of the items in FJS-12 it was difficult to assess in what category the patient answered and it may be confusing for the patient. Pain is indirectly linked to all items as patients have to be free of pain to forget their artificial joint. Improved range of motion after surgery for 187.
