"Měl problémy s oběma koleny?"

Translation: Did he have problems with both knees?

[BoneheadBass]

The Czech verb is in the past tense (MĚL). "Have" is appropriate in the translation.

[LukasBlech]

Add "Did he have problems with his both knees".

[BoneheadBass]

Nope, that one doesn't work. But "both his knees" and "both of his knees" are accepted.
