Purpose: We purposed to evaluate clinical results after undergoing arthrocopic surgery of lateral discoid meniscus in children.
Materials and Methods : Retrospective evaluation was executed for the 21 cases which showed abnormal findings of knee joint due to lateral discoid meniscus, from Janunary 1 1999 to December 30 2007. Average observation period was 38.4 months (14 months~60 months), and average age was 9.5 years old (7~12 years old). The major clinical findings for knee joint extension limitations were the most common with 11 cases, and there were 8 cases of knee joint pain, 6 cases of snapping, and 10 cases of gait abnormality. The forms of lateral discoid meniscus were 14 cases of complete type, 5 cases of incomplete type, and 2 cases of Wrisberg type. All patient had arthroscopic partial menisectomy and some patient who had meniscus tear had arthroscopic meniscus repair. The clinical results were evaluated using Ikeuchi grading system, and the change of knee joint was observed through routine radiography.
Results: The peripheral hypermobility of lateral disciform meniscus was observed in 7 cases. The peripheral tear was observed in 4 cases, where partial menisectomy was along with suture at the same time. The final clinical results were 5 cases of Excellent, 12 cases of Good, 4 cases of Fair. Radiologically, there were 5 cases of subchondral sclerosis and narrowness of hardness at the lateral knee joint, and osteochondritis occurred at the joint facet of external femur in 1 case. In clinical result, meanwhile, there were 20 cases of normal or almost normal and only 1 case of abnormal in IKDC score
Conclusion: Knee joint arthroscopic partial menisectomy for treatment of lateral discoid meniscus is useful, and when accompanied by peripheral disruption, suture is thought to be necessary.
