Sports activities and endurance capacity of bone tumor patients after rotationplasty.
OBJECTIVE
To investigate the preferred types of sports activities of patients with rotationplasty and to measure their physiologic performance characteristics through treadmill ergometry.


METHODS
Cross-sectional, descriptive analysis and repeated measures of different velocities.


METHODS
Biomechanics research laboratory.


METHODS
Patients (n=61) with rotationplasty after bone tumor surgery, 30 of whom participated in a functional trial (treadmill), and a control group (n=20).


METHODS
Not applicable.


METHODS
Patients' participation in sports compared with that of the healthy population, treadmill performance at 2 or 3 different speeds, heart rate, lactate accumulation, oxygen consumption, ventilatory equivalent, efficiency, respiratory minute volume, and respiratory quotient.


RESULTS
High activity in sports participation (85%) in most common sports (8 competitive, 17 sports club members, the remaining subjects were recreational athletes). At the same treadmill speed, lactate accumulation and all cardiorespiratory functions were higher in rotationplasty patients than in the control group.


CONCLUSIONS
Patients can re-engage in a high level of physical activity after rotationplasty for bone tumor treatment. This physical activity is necessary if patients want to maintain or improve a desired level of sports activity.
