Recurrent issues possible as with any surgical repair, it says I think. Is that referring to chronic pain?
The Muschaweck repair seems mostly for sports ‘hernia’. It didn’t work for Glen Murray, UK footballer. And I seem to remember an article about another sportsman who wasn’t too impressed. But as is pointed out, very few surgeons or techniques are 100percent positive.
It’s a modified shouldice apparently.
