Summary

The technique of all-arthroscopic AMIC-aided repair of cartilage lesions of the knee joint using the retraction system and dry arthroscopy provides promising good results with miniinvasive approach.

Abstract

Purpose

The technique of an all-arthroscopic AMIC-aided repair of cartilage lesions of the knee joint using a retraction system and dry arthroscopy has been
recently reported. We report the first clinical and radiological data at a
short-term followup.

Methods

and Materials

Twelve patients underwent AMIC-aided cartilage repair for a patellar lesion.
All steps of the procedure were performed arthroscopically. This included the
use of an intraarticular retraction plate for distraction of the patellofemoral
joint, and evacuation of saline solution for collagen matrix insertion and fixation. Clinical assessment performed before surgery and at a mean followup time of 38 months (range, 24-70) included the following scores: KOOS, IKDC, 17 and VAS. Magnetic resonance imaging was performed at the followup examination, including the MOCART score.

Results

The mean KOOS and IKDC scores increased significantly (P<.01) from 50.3
and 37.4 points preoperatively to 90.1 and 79.4 postoperatively. The VAS
decreased from 7.8 to 2.3 points. Mean MOCART score at followup was 60.1 points.

Conclusion

Cartilage repair of patellar lesions aided by a retraction system in a dry
arthroscopy setup is a promising approach. Further studies are needed to
evaluate this procedure and compare it to existing matrix implantation
techniques.
