Summary: In arthroscopic medial root ligament repair technique, the Remodified Mason-Allen technique is possible to repair anatomical position and has a high repair rate in second arthroscopic finding

Abstract:

Purpose

This study is to evaluate the arthroscopic finding of medial meniscus root tear, the Re-modified Mason-Allen technique and it’s short termresults.

STUDY DESIGN
Case series; Level of evidence, 4

MATERIALS & METHODS
From September 2012 to June 2013, Among patient who underwent arthroscopic medial meniscus root repair, 6 patients(8cases) were available for second-look arthroscopic evaluation. Instead of existing vertical suture in a bone tunnel suture pulling method, the secondary suture passed through the bone tunnel pulling downward, making horizontal loop suture. The Novel suture technique was devised for more anatomical fixation than recent technique and reducing shearing force to repaired site. Drilling tibial tunnel can infuse autologous mesenchymal stem cell in knee joint space, and “High tibial osteotomy” was performed to patient with genu varum, mechanical axis correction was to reduce the medial loading. Total 8 cases of medial meniscus root tears were treated by the Remodified technique were used for repair. Mean age was 52.1 years old and secondary after primary arthroscopic repair of the average observed for an average of 13.7 months before (413 days).

RESULT
The healing status was classified as complete healing, partial healing, complete retear. Complete healing was 7 cases(87.5%) and no case in partial healing, complete retear was 1 cases(12.5%). Average Lysholm and HSS score is improved, 69.8 to 80.75 and 69.0 to 81.0 in outpatient follow-up.

Conclusion

In arthroscopic medial root ligament repair technique, the Remodified Mason-Allen technique is possible to repair anatomical position and has a high repair rate in second arthroscopic finding.
