This report describes the use of arthroscopic microfracture to treat a 10-year-old female patient with extensive damage to the cartilage of the lateral condyle of the tibia before epiphyseal closure, resulting in good cartilage recovery. Magnetic resonance imaging showed a defect in part of the load-bearing surface of the articular cartilage of the condyle articular of the tibia. The patient was diagnosed with damage to the lateral condyle cartilage of the tibia following meniscectomy, and arthroscopic surgery was performed. The cartilage defect measured approximately 20 × 20 mm, and microfracture was performed. Arthroscopy performed four months postoperatively showed that the cartilage defect was completely covered with fibrous cartilage, and the patient was allowed to resume sports activities. Four years postoperatively, she has had no recurrence of pain or hydrarthrosis.
