Effect of atelocollagen on the healing status after medial meniscal root repair using the modified Mason-Allen stitch.

Introduction: Addition of collagen during medial meniscal root repair (MMRR) may improve meniscal root healing minimising fibrous scar tissue formation. The purpose of this study was to verify the effect of atelocollagen on MMRR using the modified Mason-Allen stitch when compared with that of the conventional pullout repair by assessing the clinical and radiological outcomes.

Hypothesis: It was hypothesised that atelocollagen would enhance the healing effect on the meniscal root following MMRR.
