Plural of arthrotomy; multiple surgical procedures involving incision into a joint.
Plural form of 'arthrotomy', from Greek 'arthron' (joint) + '-tomy' (surgical incision or cutting). The regular English plural '-ies' adds multiplicity to the singular form.
When a patient has had multiple arthrotomies, it often means repeated surgical access to the same joint—this can build scar tissue and limit flexibility, which is why modern arthroscopy (using a tiny camera) has largely replaced open arthrotomies for diagnosis and simple repairs.
