There's not a lot of data that shows we can actually isolate the VMO.

You are correct, however the muscle recruitment patterns have been studied. And the VMO is recruited, rather than isolated, in 2 situations: either when unilateral work is done, or consistent training for experienced lifters allows greater VMO activation. Most people for rehab aren't experienced at the squat, so the unilaterals will have to do.
The relationship between training status and intensity on muscle activation and relative submaximal lifting capacity during the back squat. J.Strength & Cond. Res; 14 (2):175-181.
A study published by researchers from the U.K. has shown that foot position and stance does not alter the activation of the VL or the VM in the thighs.
