Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you should wait for spontaneous healing rather than jumping directly to the surgery.
In 50% cases, such Complete tear can be heal with
1. Avoidance of weight bearing
2. Complete
bedrest.
3. Ankle cast for immobilization.
4. Painkiller and anti inflammatory drugs.
Do all thesethese for 4 weeks and get done repeat
MRI. If it is healing then no need for surgery.
But if it is non healing then get done arthroscopic surgical repair of this ligament. In this, screws are needed.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
