Patterns of meniscal injury with acute anterior cruciate ligament tears

One hundred two patients underwent an arthrotomy for the primary repair of an acute ACL tear with or without an associated collateral ligament injury. The mean age was 23 years. Forty-seven patients (46%) had meniscal injuries. Meniscal injuries were found in 41 % of Group I patients (isolated ACL injuries) and in 54% of Group II patients (injured ACL/collateral liga ments). Twenty-eight medial and 22 lateral meniscal tears were noted. Twenty-six of the 50 meniscal tears (52%) were sutured in an attempt to repair the menisci. Of these, 20 of the medial (71 %), and 6 of the lateral (27%) meniscal injuries were sutured. No patients in this series required a total meniscectomy. A thorough evaluation of the menisci is mandatory in knees with an acutely injured ACL.
