there's where I get confused from reading forums like this my percepction is in the US mobility starts earlier wherein the UK (where I live) it's standard to have the 6 weeks immobilsation - so 2 different approaches.
I understand that time is required for hte tendon to repair but as a sports person I'm not keen on the muscle atrophy and stiffness are 6 weeks of no movement.

Also any idea why they do a full plaster cast over the foot to the hip - why not just down to the ankle?
