Background. The prepatellar bursa can become inflamed owing to repeated trauma. Prepatellar bursitis is extremely rare in children. Methods. We report the case of an 8-year-old boy who was treated for an erythematous, swollen, and severely painful right knee, fever, inability to bear weight on the leg, and purulent material draining from a puncture wound. We describe the differential diagnosis for tender swollen knee, including infection, gout, rheumatoid arthritis, and osteoarthritis. If untreated, prepatellar bursitis can progress to patellar osteomyelitis. Results. Wound cultures grew Streptococcus pyogenes, with the infection resolving with amoxicillin. Conclusions. A high index of suspicion is necessary in children presenting with prepatellar bursitis to prevent potentially devastating sequelae of infection of the septic joint.
背景。髌前滑囊可因反复创伤而发炎。髌前滑囊炎在儿童中极为罕见。方法。我们报告了一名8岁男孩的病例，他因右膝红肿、剧痛、发热、无法负重以及穿刺伤口有脓性分泌物而接受治疗。我们描述了膝关节肿痛的鉴别诊断，包括感染、痛风、类风湿关节炎和骨关节炎。如果不治疗，髌前滑囊炎可发展为髌骨骨髓炎。结果。伤口培养物培养出化脓性链球菌，使用阿莫西林治疗后感染得到缓解。结论。对于出现髌前滑囊炎的儿童，必须保持高度的怀疑，以防止感染性关节感染可能造成的严重后果。
