Allograft or synthetic meniscal replacement has the potential to delay the arthritic sequelae of the meniscectomized knee. Meniscal implants must, however, be side and size specific. A cadaveric study was performed in which medial and lateral menisci were painted with a radiopaque tantalum powder-cyanoacrylic mixture. Radiographs of this preparation demonstrated reproducible relationships between each meniscus and established bony landmarks. When corrected for magnification, meniscal size could be derived from plain films. Meniscal width equaled the distance (coronal) from the peak of the tibial eminence to the periphery of the tibial metaphysis on anteroposterior films. Meniscal length was measured from lateral radiographs. Medial meniscal length was 80%, and lateral meniscal length was 70% of the measured sagittal length of the tibial plateau. Measurement error averaged 7.8% by these parameters.
同种异体移植或人工半月板置换有可能延缓半月板切除术后膝关节的关节炎后遗症。然而,半月板植入物必须根据具体的侧别和尺寸进行定制。进行了一项尸体研究,在该研究中,用不透射线的钽粉-氰基丙烯酸酯混合物对内侧和外侧半月板进行涂抹。该制剂的X线片显示了每个半月板与既定骨标志之间可重复的关系。校正放大倍数后,半月板尺寸可从平片中得出。半月板宽度等于前后位片上从胫骨隆突顶点到胫骨干骺端周边的距离(冠状面)。半月板长度从侧位X线片测量。内侧半月板长度为胫骨平台矢状长度测量值的80%,外侧半月板长度为70%。根据这些参数,测量误差平均为7.8%。
