Abstract

Meniscal allograft transplantation (MAT) is a surgical intervention for patients which is indicated in patients with painful meniscus deficiency. Accurate sizing of the meniscal allograft is paramount for normalising compartmental pressures and reducing graft extrusion. In this systematic review we explore and compare the evidence for different imaging methods for meniscal sizing.

Method

A systematic search of electronic databases identified 14 relevant studies and 1 report that matched the specified inclusion criteria. This search focused on comparisons of imaging methods, quantitative data on meniscal dimensions, and reports on accuracy rather than clinical outcomes.

Results

When considered together, radiographic measurements show a wide range of concordance with true measurements due to differences in acquisition and positioning whereas MRI measurements are relatively uniform. The comparisons between Yoon and Pollard radiographic methods for lateral meniscal length support the Yoon method although data is scarce. Studies generally agree that the menisci are symmetrical within 10 % although when compounded with other measurement errors this may become significant.

Conclusion

The trend is that MRI demonstrates more uniform accuracy over radiographic methods although when acquired correctly, the modified Pollard and Yoon methods are able to attain comparable accuracy. In the future, ideally 3D modelling is potentially the most promising method of graft to recipient matching.

期刊介绍： Journal of Orthopaedics aims to be a leading journal in orthopaedics and contribute towards the improvement of quality of orthopedic health care. The journal publishes original research work and review articles related to different aspects of orthopaedics including Arthroplasty, Arthroscopy, Sports Medicine, Trauma, Spine and Spinal deformities, Pediatric orthopaedics, limb reconstruction procedures, hand surgery, and orthopaedic oncology. It also publishes articles on continuing education, health-related information, case reports and letters to the editor. It is requested to note that the journal has an international readership and all submissions should be aimed at specifying something about the setting in which the work was conducted. Authors must also provide any specific reasons for the research and also provide an elaborate description of the results.
