Implication

Cohort study shows specific radiographic and anthropometric measurements reliably predict meniscal dimensions in 22 patients, indicating viable low-cost alternatives to MRI for transplantation.

Key Points

To compare the reliability and cost-effectiveness of anthropometric and plain radiographic sizing methods against MRI for predicting meniscal dimensions before transplantation.
Evaluated MRI scans and plain radiographs from 22 patients (44 knees) at a single center.
Measured medial and lateral meniscal length and width using the Pollard technique, Yoon technique, and anthropometric regression models factoring in sex, age, weight, and height.
Defined measurement accuracy as a discrepancy within 10% of the MRI gold standard, evaluated using Pearson correlation, intraclass correlation coefficients, and the Wilcoxon test.
The Pollard radiographic technique significantly overestimated lateral meniscal width compared to anthropometry and lateral meniscal length compared to the Yoon method (both P < .001).
Anthropometric sizing underestimated medial meniscal dimensions, achieving an accuracy of 68.2% for width and 63.6% for length compared to MRI.
Plain radiography achieved an accuracy of 93.2% for medial meniscal length and 77.3% for medial meniscal width relative to MRI.
