Introduction: OSD is a growth osteochondrosis affecting the apophyseal cartilage of the anterior tibial tuberosity of the knee, 20 to 30% of young growing athletes suffer from this pathology, described by Osgood and Schlatter in 1903. Objective: To report 2 observations and review the literature. Observation 1: This was a 14-year-old Guinean teenager, Halpoular, living in Conakry, a right-handed footballer who presented with a painful swelling of the right knee that looked mechanical, whose father had HLA B27 positive ankylosing spondylitis. X-ray of the right knee showed fragmentation of the anterior tibial tuberosities, and ossicle with edema of the patellar tendons at stage 4 according to Ehrenbord and Lagergren (1961). Thus, the disease of OSD is retained, He received 120 mg of diclofenac, 20 mg omeprazole for 1 month and the cessation of sports activity, the evolution was favorably marked by the regression of pain. Observation 2: A 16-year-old girl, initials m.L.T, Guinean, residing in Coyah (Republic of Guinea), a handball player, consulted for intense pain (VAS: 8/10) in her knees after a violent shock received when she hit the post. The physical examination found a painful, soft swelling at the anterior tibial tuberosity of the right knee, the rest of the examination was normal. The X-ray of the right knee shows fragmentation of the anterior tibial tuberosity, and ossicle with edema of the patellar tendon at stage 4 according to Ehrenbord and Lagergren 1961, thus the OSD disease is retained, the treatment instituted was 120 mg of diclofenac, the cessation of sports activity which gives a good evolution (EVA at 2/10). Conclusion: OSD is a growth osteochondrosis affecting the apophyseal cartilage of the anterior tibial tuberosity of the knee in young growing athletes, resolving at rest.
