When is it best to consult a surgeon to heal with steel? If there is a structural problem with your knee, shoulder, hip or foot then it is important to get it assessed properly by a physiotherapist. They are trained specifically to know if an injury will respond to conservative management or will it need a more aggressive response to achieve the outcome.
Surgery is necessary in some cases and no amount of exercise nor manual therapy will do the job. It is important however to speak to your Physio about pre-habilitation exercises to condition the area safely and pain free before surgery.
