O-leg can be operated, but not all cases need surgical treatment. If the O-leg is caused by epiphyseal injury or congenital developmental malformation, it can be treated by surgery. For example, epiphyseal plate fixation, osteotomy and orthopedic plate fixation, joint replacement and other methods can be used to correct O-leg. However, if the O-leg is caused by other reasons, such as osteoarthritis, you can try conservative treatment first, such as physical therapy, massage, medication and so on. Surgical treatment can only be considered if conservative treatment is ineffective.

It should be noted that any operation has certain risks and complications, so it is necessary to carefully evaluate the patient's condition and physical condition before the operation, choose the appropriate operation method and operation opportunity, and be operated by experienced doctors. At the same time, good nursing and rehabilitation training are needed after operation to promote the recovery of patients and reduce the occurrence of complications.
