Summary

Evaluated the effective of tendon healing after rotator cuff repair used modified Mason-Allen suture technique combined with microfracture procedure

Abstract

Background

Rotator cuff tear (RCT) is a lesion that cannot be reversed, usually requiring surgery. Several techniques have been introduced to repair RCT. In general, the purposes of these techniques are aimed at restoring the mechanical strength of the tendons, reducing the rate of tendon re-tear and increasing the rate of tendon healing, thereby increasing functional outcomes after surgery.

Materials And Methods

This prospective longitudinal follow-up study included 60 patients of full-thickness RCT who underwent arthroscopic rotator cuff repair with modified Mason-Allen suture technique combined with microfracture procedure at the attachment site between January 2019 and March 2020. Tendon healing was assessed based on MRI according to Sugaya classification, we also evaluated functional results after surgery based on ASES score and UCLA score

Results

Random check forty-one out of 60 patients had postoperative MRI, showing type I, type II, type III, type IV and type V tendon healing respectively in 23 patients (56.1%), 9 patients (22.0%), 4 patients (9.8%), 2 patients (4.9%), and 3 patients (7.3%). The average ASES scores before and after surgery were 28.02 ± 15.36 and 96.35 ± 4.57, respectively. The average UCLA score after surgery was 33.07 ± 1.83.

Conclusions

The arthroscopic modified Mason Allen suture technique combined with microfracture procedure for the treatment of rotator cuff tear had good postoperative results about tendon healing and functional outcomes, especially in patients with small, medium, large tears
