In my opinion it will be never normal as pre injury status. you will feel difficulty while walking on uneven surfaces, taking turns suddenly, dancing, and feel instablity in the knee while walking. but the chances of getting this symptoms vary and depend on your physical activity and the physiotherapy may get you upto 75% of your pre injury status by maintaining your muscle tone. but the chances of arthritis and meniscal injury also there. its a decision to be taken by the patient to wait for surgery because how much physical activity you want do depends on you. as you like swimming and dancing please choose your option wisely.

First of all, acl ligament tear will not heal by its own ..ligament recreconstruction is the only solution in your case and also then only u can carry out your sports type activities. Second thing waiting for such a long time is not advisable as internal derangement may lead to medial meniscus tear and early arthritis changes due to cartilage erosion..so better to go for arthroscopic acl reconstruction as soon as possible till that time keep doing quadriceps strengthening excersises andROM excersises that will help you in post operative rehabilitation.

Yes U can wait but avoid any physical activity as any new injury will damage cartilage and meniscus.

Yes you can wait. You can lead your life normally with due precautions and exercise. Surgery is not compulsory if your demand is less. ACL surgery is reconstruction and not repair ..so it can be done at any point in your life. I hope this answers your questions. Take care.

In fact there is a protocol to wait for 3 months before embarking surgery except in few selected situations. But this time you should use doing supervised physiotherapy to maintain your muscle mass and tone.
