This retrospective study reviewed the outcomes of 43 knees in 38 patients with discoid menisci treated from 1977 to 1989. Patients underwent either no treatment, trimming, or subtotal or total resection. Approximately 40% of patients who underwent meniscectomy or partial meniscectomy had a fair or poor rating after an average follow-up of 6.5 years. Pathology demonstrating mucoid fibrinous degeneration within the discoid meniscus was found in many cases, showing abnormal meniscal tissue. Only one third of these knees had symptoms of locking, and only 20 (63%) of 32 had a positive arthrogram, demonstrating the diagnostic difficulties encountered with the discoid meniscus. Patients with a discoid meniscus who are symptomatic should undergo arthroscopy. A partial meniscectomy should be performed to achieve a smooth meniscus and a strong, stable peripheral rim.
这项回顾性研究评估了1977年至1989年间接受治疗的38例盘状半月板患者的43个膝关节的治疗结果。患者接受了不治疗、修整、次全切除或全切除。在平均随访6.5年后，接受半月板切除术或部分半月板切除术的患者中约40%的评级为一般或较差。许多病例的病理显示盘状半月板内有黏液样纤维变性，表明半月板组织异常。这些膝关节中只有三分之一有交锁症状，32例中只有20例（63%）关节造影呈阳性，这表明盘状半月板的诊断存在困难。有症状的盘状半月板患者应接受关节镜检查。应进行部分半月板切除术以获得平滑的半月板和坚固、稳定的周边边缘。
