Unresolved osgood-schlatter disease in a skeletally mature female managed with bursoscopic debridement

Introduction and importance: Osgood-Schlatter disease is one of the common causes of knee pain among sports-practicing adolescents. It usually presents in skeletally immature adolescent male with unilateral knee pain. The disease is often self limiting and managed conservatively. Case presentation: We report a case of a female in her early 20s who presented with pain over the tibial tuberosity in the right knee for six years, with no history of involvement in any sports-related activities. The diagnosis was made based on the MRI of the right knee, which showed abnormal signal intensity in the tibial tuberosity. After conservative management for about one year, the patient underwent bursoscopic debridement of ossicles and tibial tuberosity. WOMAC score at follow-up of 1 year and 2 year was 1/96 and 0/96. Clinical discussion: Osgood-Schlatter disease is common in adolescents involved in sports related activities, with earlier onset in females due to earlier bone maturation. Presentation in skeletally mature females and without history of sports related activities is rare. Usually 90% of the cases improve with conservative management, however, surgical debridement was required in our case. Conclusion: Osgood-Schlatter disease should be considered a differential diagnosis of anterior knee pain in a young adult. Bursoscopic debridement can be done in patients with persistent knee pain unresponsive to medical management
