See the attached images. I have seen several surgeons engage in this ethically questionable practice (Antipov is another). It's problematic for at least three reasons:
(1) Conflict of interest: Employees are compensated by their employer and thus rely on their employer's economic success for their livelihoods. Consequently, they have economic incentives, albeit somewhat more attenuated than their employer's, to leave positive reviews. The impartiality of employee or employee/patient reviews is thus suspect.
(2) Undue influence: An employee or employee/patient might face adverse consequences for leaving negative reviews or not leaving a review at all for their employer. For this reason, the impartiality of an employee or employee/patient review must be questioned.
(3) Patient experience: If indeed the employee is a patient, the patient/employee has the benefit of day-to-day monitoring from the surgeon and if the employee's status as a patient is public, the employee becomes a visible exponent of the surgeon's work. For this reason, the employee/patient is likely to receive post-operative attention and care that might be different from that of the standard patient.
At a minimum, a patient reviewer who is an employee of a surgeon should disclose such relationship.
