ACL recon and meniscus repair are not even remotely similar. the fact of how weak the graft is not open for debate. Most doctors are very conservative as there is no downside to protecting the graft. after 6 weeks or so, the knee and surrounding leg muscles should be strong enough to support the knee well enough from moderate impact and twisting even though the graft is not fully stable. Can you do without the brace, absolutely. should you....... What is to be gained?
Meniscus tears are different as the weight of the person can cause a lot of pain and swelling. but once it's repaired it should be stable. The vast majority of meniscus are repaired by clipping the tear so there is really no risk of causing more damage. the 1st time I had meniscus tear repair I was off of crutches in 2 days but walking around quite a bit but it really depends on how much and where the damage was. It also depends on the surgeon and that techniques they use. All surgeries are not alike.
This is true. However, mine were repaired with sutures, not resected. I believe that changes things.
Like we all keep saying, each surgery is different.
