Priyanka, you haven't mentioned your Category. This is important because the cut offs are different across Categories. Neverthless, this answer is being written assumed that you belong to General Category. Going by previous years cut offs and your rank, you have decent chances at various specializations. And this is the data:

MD in Anaesthesiology:

Dr. D.Y.Patil Vidyapeeth

Chettinad Academy of Research and Education

Meenakshi Medical College

ENT:

Meenakshi Medical College

VMKV Medical College

Vinayaka Missions Medical College

General Surgery:

Aarupadai Veedu Medical College

Sree Balaji Medical College and Hospital

Orthopaedics;

Sree Balaji Medical College

Santosh Medical College

Sri Lakshmi Narayana Institute of Medical Sciences

Now this is 2019 data and cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, difficulty of the exam, and no.of seats available for each specialisation.
