PCLavulsion fracture of tibia (6-7mm displacement) with adj tibial bone edema. Grade1 strain of ACL. Grade2strain lateral coll lig strain. Is surgery req?

Yes, it should if- -U expect 2 have a functioning knee 4 the rest of Ur life. It can only separate more, & a simple reduction & fixation will do what U want it 2 do, reunite the fragment 2 the tibia. The image is a tear & requires a major reconstruction if not fixed. U risk the fragment becoming a nonunion.
