Talk to Orthopedic Surgeon on Right Knee Injury

3 months ago i injured my right knee.I rushed to the emergency and the doctor took my X-Ray and said rest for three week. After 3 weeks doctor checked the dislocation in my knee and he said there is no such sign of dislocation and you have a little bit of swelling so rest for a month and if you will still feel pain we will do the MRI. My MRI done and the report says:<conclusion> 'Findings are of mild knee joint effusion,complete tear of anterior cruciate ligament and Grade 3 tear in anterior horn of lateral meniscus with Grade 2 tear in posterior horn of medial represent post traumatic sequelae'. The doctor reffered me to an orthopedic surgeon. The surgeon thoroughly checked my knee and said that clinically you didnt have any severe problem so do physiotherapy for 1.5 months and if you dont feel any difference we will do my question is that do i have and any other treatment option for this.
