In 1950 O'Donoghue called attention to “that unhappy triad which comprised (1) rupture of the medial collateral ligament, (2) damage to the medial meniscus, and (3) rupture of the anterior cruciate ligament” and recommended early surgical intervention.Ten patients with arthroscopically confirmed acute (<1 month) tears of the medial collateral ligament (MCL) and anterior cruciate ligament (ACL) were identified. There were 9 men and 1 woman with an average age of 33.4 years (range; 17-52 years).There was a 50% incidence (5 knees) of lateral meniscal tears. Of these, 1 knee had an associated medial meniscal tear. There were only 2 knees (20%) with medial meniscal tears. Chondral injuries to the lateral compartment were noted in 4 cases. There were 3 knees without meniscal tears and chondral injury.We conclude that the “unhappy triad” is an unusual clinical entity with knee injuries and may be more accurately described as a triad consisting of ACL, MCL, and lateral meniscus tears.

不幸の三徴候(Unhappy Triad)は1950年に定義した先生の名を冠して、 O'Donoghue's Triadとも言います 今では定義も破綻していると言われていて、文献にもありますが、内側半月よりも外側半月の方がACLと共に、損傷し易いと言われていますね 参考文献)https://t.co/HtpHZapoUJ #膝オタク
