Hi
With all due respect to the orthopaedic surgeon, they are experts at fixing bones but don't often have a holistic approach.
A good physio will check you bones, muscles, joints, nerves, motor control, compensations etc etc etc not only for your femur, hip and knee but for your pelvis, lumbar spine, thoracic spine, ankle, foot etc etc.
An assessment with a physio to see what the status of your body is and what options you have.
The cycling and swimming are good exercises but as a physio, i am interested in HOW you are cycling and swimming, not whether or not you are doing it...
Does that make sense?
For example, i had a patient who had a bad car accident - she needed me to plaster her arm, had fractured ribs, whiplash etc. I did the cast and offered help for her ribs because it was obvious she was in a lot of pain. However, she said she was advised not to let anyone touch her for 3 weeks. Good general advice but good treatment can help. So 3 weeks later she still had trouble breathing and moving without pain. I used some simple treatment techniques and some taping and all of a sudden, she took her first pain free deep breath. She remarked "why did you do that 3 weeks ago" and i replied "you wouldn't let me!".
The moral of the story is that maybe a physio can help you more than you or the surgeon thinks!
I hope that helps - sorry for rambling!
