Workout/contact sports after major operation

Tanong ko lang po sa mommies na nag undergo ng major surgeries (di po ako CS pero naoperahan last 2018 dahil sa ruptured fallopian tube) kung kelan kayo nagstart ulit ng heavy workout/contact sports? I used to play muay thai kasi and my OB advised me that I can resume working out after 2 yrs. I want to know your personal experiences sana sa pagresume sa heavy workout after major surgery
