[A deep sigh] I would be happiest if you waited another day before you left, but... Give it another few hours so that we can verify that you didn't suffer from any complications. After that, once you manage to walk the length of the medibay both with and without assistance, and agree on an escort back to your berth? Yes, you can go.

In the meantime, I will order you painkillers for your knee while you are still here, but I will have a nurse deliver it if you prefer.
