Do i need surgery for a partial tear of the medial meniscus posterior horn root?

Maybe: A finding of a tear on MRI does not mean you need surgery. The key to determining if you need surgery is reproducible pain that prevents you from performing the activities that you enjoy. Swelling is another factor that would indicate that surgery is necessary.

Meniscal tear: The indications for surgery are locking or catching, knee giving way, recurrent fluid on the knee, pain that you can't live with, and failure of conservative treatment.

Possibly: Meniscus tears can heal on their own if they are small. Otherwise, sometimes they can just become asymptomatic and no longer cause pain. If they continue to cause symptoms such as pain and swelling after 6 to 8 weeks, then surgery is usually required. This involves a knee arthroscopy which is an outpatient procedure.

It depends: It depends on whether it is causing enough symptoms to warrant surgery. Many small tears seen on MRI are related to degenerative changes in the meniscus and do not require surgery.
