A fully torn ACL is a clear cut indication for surgical reconstruction.
Initially you might get away without much pain and discomfort for a few months.
But this will only lead to joint degeneration and put your meniscii in danger of tear.
My advice. ..the sooner you get it operated, the better.
Also , since you are an active sportsperson get it arthroscopically operated by a surgeon who is well versed
with the patella
tendon graft procedure.
