ЕPIDEMIOLOGY OF 'O'DONOGHUE'S TRIAD'

The term "Unhappy Triad", coined by O'Donoghue, reflects a severe knee injury with rupture of the medial collateral ligament, medial meniscus, and anterior cruciate ligament. The triad is primarily a sports injury, and patients' recovery is 6 to 12 months. Material/Methods: 70 patients with "O'Donoghue's triad" were studied. Total anterior cruciate ligament rupture was reconstructed with patellae ligament autograft; medial meniscus tear was treated with partial meniscectomy; and medial collateral ligament injury was treated conservatively at 1 month before surgery. The aim of the study is to establish the epidemiology of the injury: age and gender distribution, distribution by types of sports in patients with "O'Donoghue's Triad" after arthroscopic treatment. 222 persons were examined in two stages – first, 187 with various soft tissue injuries of the knee, after surgical treatment, including persons with the triad, and second, 70 patients with O'Donoghue's triad. Results: The study shows that among 18-19-year-olds, the triad was found in 4 people; from 20 to 29 in 34, from 30 to 39 in 23, and from 40 to 49 in 9. In terms of gender, there were 62 men (86.11%) and 8 women (13.89%) with the triad injury. "O'Donoghue's Triad" was obtained during sports in 91.52% of cases, the remaining 8.48% in car accidents and household accidents. Conclusions: The results of the study establish and provide coaches, physiotherapists, orthopedists, scientists and educators with up-to-date data on the epidemiology of O'Donoghue's Triad, its incidence, age and sex characteristics and its distribution by sport.
