Hi Bara, to answer your question: A grade 2 ACL tear is as good as a full tear. You should read this blog to better understand what the difference is and what your treatment options are:
optimalrecoveryclub.com/blogs/acl-info/acl-injury-treatment-options If you have suffered meniscal damage, non-operative treatment is not ideal as the tear can propogate (grow) and become a real issue. Some areas of the menisci do not heal, so if the tear propogates badly, your knee can suffer irrepairable damage. If your meniscus is in good shape, non-surgical treatment is a viable option. Non-operative treatment is called Conservative Management (CM) as outlined in the above blog post.
As
@saffe has outlined above, its possible to try CM first, and if you're still having issues then go for surgery. CM also puts your knee in great shape for surgery and can accelerate post-op recovery timelines.
So, regardless I'd highly recommend you see a physio experienced in sports rehabilitation and begin work either on CM or a pre-operative rehabilitation and begin work now assuming your inflammation has reduced.If you're seeking some physio's or ACLR surgeons in Perth PM me and I can give you some recommendations.
I'm 3 years post-ACLR following a grade 3 (full tear) in Lano windsurfing in late 2015. Since tearing my ACL I reached out to one of Australia's top ACL Rehab specialists, Dr. Jay Ebert, and created a full guide to ACL Recovery. ACLR Rehab is a rapidly evolving space and the goal was to partner up with a leading professional on the cutting edge and create a holistic guide to ACL recovery (physical, mental & nutritional). We've just launched the guide and continuing to develop it into a high quality ACL recovery resource. It features a 6 week pre-hab protocol that'd be useful for you heading into surgery. Link:
