Purpose / Aim of Study: The study aim was to assess work ability and physical activity (PA) in these patients. Materials and Methods: This cross-sectional study compared employed patients, receiving LSS and reconstruction in proximal (n=9) or distal femur (n=7) or proximal tibia (n=4) between 2006 and 2016, with employed healthy controls (n=20). The Musculoskeletal Tumour Society Score (MSTS) was used as descriptive information. The Work Ability Index (WAI), financial difficulties, the Patient Specific Functional Scale (PSFS), activity monitor and the International Physical Activity Questionnaire (IPAQ) were used to evaluate work ability and physical activities. Between group differences were assessed using unadjusted and adjusted (sex, age, BMI, educational level, type of work) general linear models. Findings / Results: The patients were seen on average 7 (±2.9) years post- surgery, had a mean age of 43 (±13.6) years, BMI 27 (±3.7) and MSTS of 69 (±14.6)%. Six patients (30%) experienced that their physical condition had caused financial difficulties. The adjusted analyses showed differences in general work abil- ity (7.8 vs. 9.1 points, p=0.002) and work ability due to physical demands (3.2 vs. 4.6 points, p<0.001) between patients and controls. There were between group differences in PSFS mean score (2.8 vs. 9.5 points, p<0.001). No differences were seen in step counts/day (10588 vs. 12239 steps, p=0.144) or the IPAQ (4107 vs. 4035 METs/week, p=0.942). Conclusions: Most patients experienced difficulties in performing tasks requiring physical demands at work. Furthermore, 1/3 reported financial difficulties caused by their condition. Although we found no differences in PA, patients reported great difficulties in performing activities that they scored as important. Assessments of work demands and collaboration with workplaces should be considered in rehabilita- tion following LSS and reconstruction with tumour prosthesis. 72.
