My dictionary (Pleco) only has "knee" as the meaning. The same is true of MDBG.

But it doesn't make sense to have "knee" there. So what is the meaning in this context?
It comes from a net slang &quot;给你跪下了&quot;(I'm kneeling down to you) or &quot;给跪&quot; for short, to show one's admiration when something is far beyond his ability.

你能吃六碗饭？我给你跪下了！
你微积分考试得了满分？给跪了。

And this has variants like &quot;献上我的膝盖&quot;, &quot;给你我的膝盖&quot; or &quot;膝盖给你&quot;, where &quot;give you my knees&quot; just means &quot;kneel to you&quot;. So basically you can take 膝盖 as a metaphor for admiration, e.g.请收下我的膝盖
