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.

Healing process of torn human anterior cruciate ligament (ACL) was studied histologically. Torn anterior cruciate ligaments were obtained from 21 patients at primary ACL reconstruction and stained with hematoxylin and eosin. Patients age was from 16 to 40 years. The interval between initial injury and operation ranged from 2 to 30 days. At 2 days after ACL injury, fibroblasts were not seen in the torn ligament and lymphocytes appeared in the injured ligament. Although vascular endothelial capillary buds and fibroblasts appeared around the torn ligament at 11 days, few fibroblasts were seen in it. At 30 days, torn ligament shrank macroscopically and resembled scar tissue with irregular alignment of fibroblast and collagen fiber. In conclusion, torn ligament is not healed probably due to few fibroblasts proliferation.
