Fifty consecutive limited arthrograms in acute knee injuries are reported with operative findings in 27 knees. The arthrograms were completely accurate regarding cruciate and medial collat eral ligament integrity in 82% of all of the cases. Improvements in technique and recognition of superimposed anatomical struc tures led to fewer errors in interpretation as the series pro gressed. Limited arthrography is recommended as a useful office procedure in the early evaluation of knee ligament integ rity in acute painful knee injuries.
