Can i still get reconstructive surgery on torn ligaments and tendons i tore 4 years ago?

Yes it is possible: It is possible but depend on what tendon and ligament and what conservative treatment you received and your symptoms and what the present imaging studies like mri/cat scan show at this time. Discuss with your orthopedic surgeon if it is possible in your case.

Repair tendons: You can always repair your tendons and ligaments but the effectiveness will depend on where they are located and if the local muscles are still functioning.
