Dr. Ma Guiwen's operation on the big foot bone is microporous and there is no pain during the operation. The operation on both feet only takes about 1 hour, and they can walk after operation, but they need to be fixed and bandaged for about 5 weeks after operation. In principle, try to stay in bed for the first two days after operation, try not to exercise vigorously and less for two weeks, and try to wear loose and suitable shoes for three months.
