It really depends what you mean by "medical complication". If we are assuming that we are getting the implant at hospital by a qualified physician risks are already at minimum.

Most likely "complications" would be body rejecting the implant or the wound getting infected. I've had foreign objects in my body (not by choice), they were removed because the wound got infected. I was monitoring the wound, once I thought it didn't look/feel normal I went to clinic and got it checked. Over all I wasn't out of commission for even full four weeks.
