I had surgery for a torn meniscus on one knee. the type where the torn part is removed, not repaired. A week and a half later the knee feels great, I have 100% full extension, and can bend it nearly full without noticing any discomfort. Basically no pain except for tenderness at the incision points. So I'm very pleased. However, I do feel like I still notice a nagging sense of "you better not plant and twist or you'll tweak it". My initial injury was 8 weeks before surgery, in that time period I experienced the same thing, where my knee basically felt 100% for almost any activity except tennis. And I had that same nagging feeling, sort of a hint of impending trouble should I try tennis. And sure enough the two times I tried to play I tweeked my knee within a few minutes and was done. (presumably the loose tear catching and tugging) So I feel like that sensation should be gone post surgery, since there is no more loose material. But as I said, I kind of have that similar sensation, like my knee is telling me "don't plant and twist" Of course it may simply be that's because it's only a week and a half out of having part of my meniscus removed, and I also may be paranoid after living with this nagging feeling for 8 weeks. But I'm curious if any others who've had the surgery know what I'm talking about and might be able to reassure me that this is simply part of the recovery that will go away in time. I don't intend to try to play until cleared by my Doc, which will be 4 weeks minimum. And I've been doing PT daily.
