Objective: To evaluate the impact of morbid obesity on physical capacity, joint-related symptoms, and on the overall quality of life. Method: Cross-sectional study carried out at a university hospital, enrolling 39 individuals admitted to a bariatric surgery service. Physical capacity was assessed by Six-Minute Walk Test (SMWT) and the Borg rating of perceived exertion (RPE). Knee-related symptoms were evaluated by Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Lysholm Score. Quality of life was evaluated by Short Form 36 Health Questionnaire (SF-36). Results: On SMWT, the mean distance walked was 374.1 ±107.5 m. The mean Borg score was 12.9 ±2.4. KOOS questionnaire found the following scores: Pain (64.3 ±24), other symptoms (67.2 ±25.5), function in daily living (60.4 ±26.8), function in sport and recreation (28.5 ±32.2), knee-related quality of life (35.9 ±33.5), mean Lysholm scale score (55.3 ±25.4). SF-36 provided the following scores: Physical functioning (41 ±27.4), physical role functioning (34.6 ±39.2), bodily pain (45.7 ±23.6), general health perceptions (63.1 ±26.2), vitality (53.5 ±12.1), social role functioning (52.6 ±29.3), emotional role functioning (41 ±44.9), mental health (55 ±27.7). Conclusion: Obesity led to significant loss of physical capacity, gait impairment, knee-related symptoms, and a negative impact on the overall quality of life.
