Nice clip Mike,
This Achilles looks like a complete future to me that has slightly scarred up.
It is certainly a major injury and I doubt very much this tendon has any real strength left.
There is some paradoxical movement, however some of it looks like it has “glued up” a bit following the injury.
I would be suggesting an orthopaedic opinion for management with an MRI to confirm and quantitate your findings.
Nice work.
