Pavard sustained the injury in Saturday's 2-1 win over Atalanta.
The summer signing from Bayern Munich has racked up nine appearances for Inter so far with the Nerazzurri top of the Serie A table and second in their Champions League group behind Real Sociedad.
“Benjamin Pavard underwent a medical examination at the Humanitas Institute in Rozzano this morning,” the Serie A leaders said in a statement on Monday.
“The tests ascertain that he has suffered a dislocated kneecap.
“The French defender will need to wear a knee brace for 3/4 weeks before starting his rehabilitation process.”
Pavard, who won the FIFA World Cup in 2018, will also be unavailable for selection when France conclude their European championship qualifiers against Gibraltar and Greece later this month.
