This high failure rate at midterm follow-up would argue against the use of unicompartmental replacement in the obese individual.
here in Philippines, obesity is also becoming a problem. More and more children are getting obese due to a lifestyle that is not fully of physical activities. most kids just wants to watch TV, play computer games and surf the net.
