Osgood–Schlatter disease resolves or becomes asymptomatic in the majority of cases. One study showed that 90% of reported patients had symptom resolution in 12–24 months. Because of this short symptomatic period with most patients, the number of people who become diagnosed is a fraction of the true number.
Tenderness in the tibial tuberosity can arise from Osgood-Schlatter disease or deep infrapatellar bursitis.A bony prominence on the tibial tuberosity can be the result of ongoing Osgood-Schlatter’s irritation in an adolescent with open growth plates, or what remains of Osgood-Schlatter’s in adults.

Osgood at Harvard, c. 1886. William Fogg Osgood was born in Boston on March 10, 1864. [1] In 1886, he graduated from Harvard, where, after studying at the universities of Göttingen (1887–1889) and Erlangen (Ph.D., 1890), he was instructor (1890–1893), assistant professor (1893–1903), and thenceforth professor of mathematics.
The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.
In mathematics, Osgood's lemma, introduced by William Fogg Osgood (), is a proposition in complex analysis.It states that a continuous function of several complex variables that is holomorphic in each variable separately is holomorphic.
The Ramberg–Osgood equation was created to describe the nonlinear relationship between stress and strain—that is, the stress–strain curve—in materials near their yield points. It is especially applicable to metals that harden with plastic deformation (see work hardening ), showing a smooth elastic-plastic transition.
The first examples of Osgood curves were found by William Fogg Osgood () and Henri Lebesgue ().Both examples have positive area in parts of the curve, but zero area in other parts; this flaw was corrected by Knopp (1917), who found a curve that has positive area in every neighborhood of each of its points, based on an earlier construction of Wacław Sierpiński.
