"She's had both available techniques, your bog standard anterior thats been around since forever and more recently an interior method. The latter was way better, recovery time halved, hardly any recovery restrictions, much less discomfort, no muscle loss around incision, hardly any physio required...everything was so much better / easier.
If you have a procedure option, def choose interior."
Sorry but this doesn't make sense. There is no such approach as interior [unless the surgeon was a Kiwi...]
Posterior is very old fashioned.
Lateral is still routine
Anterior needs a very good surgeon and we [the Royal National Orthopaedic Hospital] see many patients with unstable joints, or joints that have been excessively lengthened with associated nerve damage, referred in by other hospitals.
I have seen far more injured nerves in the last 10 years than in the preceding 20, mostly caused by the Anterior approach.
