I use unloader brace (Left Lateral) and this does allow me to carry on with most activities.
Some comments I had ... don't wear it at the gym as you need to build strength in quadriceps and unloader would prevent this.
I do a lot of water-skiing & scuba diving ... and you can't wear unloader brace in the water ....... they have offered me a very expensive CTI brace for this.
Look like my way forward is an inter-positiional device.
However not the off-the shelf metal version (iForma ?) but a purpose made unit, which is modeled after a full scan of knee.
This in my case would realign knee, and avoid the unloader ........... at least that seem to be the theory.
