How common are dislocations after surgery?

Hi! I’m 50f and had PTHR (R side)on Oct. 25th. So 2 weeks out! In the first week, My doctors sent over a brace incase there is a dislocation. Since then, I’ve been low key stressing about a possible dislocation. Does it happen often? I’ve been careful not to do too much and step weird and I’m now walking with a cane but I still feel a bit scared. Anyone else feel this way? Thanks for your support!
