If MIS surgery is done, the benefits would include less pain, less bleeding and less risk of infection.
The hospital stay is also shorter. It has as good a result as traditional open surgery (published results in international journals just last year).
Pain is definitely less than traditional open surgery, and I have had patients who even do not complain of any pain at all.
Patients would be able to weight bear the same day after surgery, in a special post-operative surgical sandal. So they would be able to ambulate straight away. There is no need for any casting/ plaster of Paris.
