Using radiographic measurements to predict meniscus size can enhance presurgical meniscus transplantation planning. Therefore, we aimed to predict the size of the medial meniscus through radiographic measurement of the medial proximal surface of the tibia. Twenty-four pelvic limbs from medium and large breed dog cadavers had radiographs, and measurements were made from the tibial plateau length in mediolateral 90° and 135° stifle positions (TPL ML90 and TPL ML135) and medial tibial condyle width in the craniocaudal position (MTCW CrCd). The menisci were brushed with a positive contrast mixture, and radiographs were repeated at the same positions. The radiographic brushed meniscus was measured for each length position (CMML ML90, CMML ML135) and width position (CMMW CrCd). The anatomic size (the actual meniscus) was measured for the width (AMW) and the length (AML) and was compared with the radiograph after contrast was added to the meniscus. The ratio (%) of the positive contrast meniscus and conventional radiographic measurements in all positions were ML90 = 83.4 ± 6.9%, ML135 = 85.3 ± 8.11%, and CrCd = 97.9 ± 5.1%. Linear regression analysis equations based on the radiographs measurement values predicted (p ≤ .01) the size of the meniscus (CMML ML90 = 9.7+0.433×TPL ML90; CMML ML135 = 11.7+0.371×TPL ML135; and CMMW CrCd = 2.9+0.775×MTCW CrCd). The intraclass correlation coefficient was used to quantify the agreement between AMW and AML with contrasted radiograph measurements [0.89 for CMMW CrCd (p < .01), 0.91 for CMML ML90 (p < .001), and 0.89 for CMML ML135 (p < .001)]. In conclusion, the width and length of the medial meniscus can be predicted based on the radiographic tibial plateau and medial tibial condyles measurements.
使用影像学测量来预测半月板大小可优化术前半月板移植规划。因此，我们旨在通过对胫骨近端内侧表面进行影像学测量来预测内侧半月板的大小。对24个中大型犬尸体的骨盆四肢进行了X线摄影，并在内外侧90°和135°膝关节位置测量胫骨平台长度（TPL ML90和TPL ML135），在前后位测量内侧胫骨髁宽度（MTCW CrCd）。用阳性造影剂混合物刷洗半月板，并在相同位置重复进行X线摄影。对造影后的半月板在每个长度位置（CMML ML90、CMML ML135）和宽度位置（CMMW CrCd）进行测量。测量解剖学大小（实际半月板）的宽度（AMW）和长度（AML），并将其与半月板添加造影剂后的X线片进行比较。所有位置阳性造影半月板与传统影像学测量的比率（%）分别为：ML90 = 83.4 ± 6.9%，ML135 = 85.3 ± 8.11%，CrCd = 97.9 ± 5.1%。基于X线片测量值的线性回归分析方程可预测（p≤0.01）半月板大小（CMML ML90 = 9.7 + 0.433×TPL ML90；CMML ML135 = 11.7 + 0.371×TPL ML135；CMMW CrCd = 2.9 + 0.775×MTCW CrCd）。组内相关系数用于量化AMW和AML与造影X线片测量之间的一致性[CMMW CrCd为0.89（p < 0.01），CMML ML90为0.91（p < 0.001），CMML ML135为0.89（p < 0.001）]。总之，基于胫骨平台和内侧胫骨髁的影像学测量可预测内侧半月板的宽度和长度。
