Hi, thanks for writing to HCM.
You have not specifically mentioned which ligament is torn in the knee (as there are four ligaments in the knee - 2 cruciates & 2 collateral ligaments).
A conservative method of treatment is advisable for Gr 1 or partial tears with atleast 4-6 weeks of immobilization in a knee brace
followed by gradual returning activities along with muscle strengthening physiotherapy
Complete or Gr 3 tears generally needs surgical reconstruction.
scan of the knee joint is mandatory to exactly diagnose your condition.
There are many good surgeons as well as excellent centres in chennai that deal with ligament injuries. And the choice is yours.
Hope this information is helpful. Good day
