A doctor performing an unorthodox but legal procedure can face potential legal and ethical issues, even with signed consent documents from the patient. If the procedure is the best available option and the patient is fully informed of the risks, the doctor is generally protected. However, if the doctor fails to disclose safer alternatives or if the patient does not truly understand the consent due to rushed explanations or misleading information, this could undermine the validity of the consent. In the UK, to establish medical negligence, it must be proven that a duty of care existed, that this duty was breached, and that the breach caused harm. Complications arising from the procedure must be linked to the doctor's negligence, not just standard risks associated with the operation. Claims against consent to treatment are challenging, particularly for competent patients, as signed documents typically affirm understanding of the procedure and its risks.
