The Unhappy Triad The “unhappy triad” refers a sprain injury that involves three structures of the knee. These structures are the medial collateral ligament, anterior cruciate ligament, and the medial meniscus. The unhappy triad is a severe injury, and it is named such because the athlete who suffers it typically becomes really unhappy. The severity of this injury typically leads to surgery to fully correct. What Causes the Unhappy Triad? The mechanism for the unhappy triad injury occurs when a lateral force to the knee is received while the foot is fixed on the ground. This places an increased valgus, or abduction, and rotational stress on the knee that results in the overstretching of these three structures.
