Stretched ACL

About 4 years ago I stretched my ACL while running in the woods and hit a wet spot, my knee buckled, and my orthopedic surgeon said I stretched it.
He didn’t give me a brace or anything for it, just told me to strengthen the muscles around it, but I am going to start playing basketball regularly and exercising and things of that sort and am wondering if I should get a brace for my knee, cause I have bad luck with my knees and am afraid I will blow it out.
My other knee I dislocate the kneecap and have a lateral J knee brace and that really helps a lot, and I figure I should wear that one too while playing basketball and working out and stuff right?
