In Nordic/Scandinavian countries, "taking an arrow to the knee" meant that you are getting married/already got married. It refers to when we propose, we fall to one knee, comparing it to when a man gets shot in the leg, he, of course, falls to one knee.
Like most definitions already posted the most popular example comes from Skyrim: "I used to be an adventurer like you, but then I took an arrow to the knee". The guards are married, and can't go out adventurer, not crippled.

Get the Arrow to the Kneemug. 
While riding four-wheelers with our friends in the woods I had to "go bad" and while I was pulling down my thong underwear I was told I was knocking an arrow!

Get the Arrow shootmug. Cupids arrows are when someone shows you affection you get a tiny needle point pain in your heart, but it's good. Similar to the heart break feeling. Also phrased and/or known to feel like they are breaking your hearts "walls" down.

Get the Cupids arrowsmug. Arrow to the knee is kind of a joke that originated from a video game called Skyrim. The line from the game is "I used to be an adventurer like you...then I took an arrow to the knee". Many people like to use the phase "...arrow to the knee" at the end of a sentence to compare themselves to what the person can do, or what they are doing.
Man 1 I used to write like you... until I took an arrow to the knee.
Man 2 What?
Man 1 An arrow to the knee.
Man 2 Sorry to hear that.
Man 2 What?
Man 1 An arrow to the knee.
Man 2 Sorry to hear that.
