Good clinical results can be obtained along with reduced risk of tunnel communication with a new technique in concomitant meniscus transplantation and ACL reconstruction.

PURPOSE: The purpose of this study was to introduce our technical modification for concomitant meniscus transplantation and ACL reconstruction with preliminary results of our cases.

METHODS

The current study comprised of two sections: first is the cadaveric study of 20 specimens. The distances between tunnel entry and exit points of tunnels for 27 meniscal transplants and ACL reconstruction in CT slices were measured. The second section was evaluation of our cases including six patients. The selected patients were scored preoperatively and post-operatively with KOOS, Lysholm and VAS Scoring systems, joint ROM and stability.

RESULTS

In cadaveric study section, the minimum distance between tunnels was found 1.9 ± 0.4 cm on tibia plateau and 1.8 ± 0.9 cm on tibial crest. No overlapping or communication of the tunnels was seen on any CT slice. In case series section, the mean age of patients was 36 ± 12.7 years and mean follow-up period was 30.8 ± 11.3 months. The KOOS total, VAS and Lysholm scores of the patients were significantly increased (p = 0.012, 0.036 and 0.001, respectively). The stability of operated knees was normal or near normal.

CONCLUSION

The results of this study have demonstrated that our technical modification seems to be an effective method in concomitant medial meniscus transplantation and ACL reconstruction. There is a reduced risk of tunnel communication, and the medial bone stock is protected so the risk of potential fracture in the medial tibia plateau and revision rates may be reduced. Although it seems successful in respect of the short-term results, further studies with a greater number of patients would provide clearer results.
