Teardrop implants can rotate. But if the implant fits the tissue, and if the surgeon makes a pocket that fits the implant, then rotation should be a very infrequent problem. But it always remains a risk with anatomically shaped implants. It is a reason why shaped implants aren’t always a good choice for revisions. It is the pressure of fresh tissue on the implant that helps maintain its position, and in revisions that is often not the case.
