Tibial tubercle fractures are uncommon fracture patterns, commonly seen in adolescents who are growing toward skeletal maturity and typically affect young males engaged in various sports. Odgen classification describes 5 types of tibial tubercle fractures. Type III is the most common. appropriate management can be guided based on the level of fracture and the presence of fragment displacement. Commonly open reduction with internal fixation by one or two screw parallel to the joint are showing satisfactory outcomes. This report highlights a 13-year-old male patient who had a history of fall down and was diagnosed with tibial tubercle fracture Ogden type III & Salter-Harris type II. He underwent Open reduction with internal fixation by one-third semi-tubular plate and screws. Patient clinical and radiographical status after 3 months follow up showed healed fracture without hardware complications and good function with no limitation in ambulation or joint range of motion. The technique used in this case appeared to be safe with an excellent functional result and has a similar outcome compared to fixation by screws.
