Abstract:

Objective

To compare the efficacy of allograft acellular dermal patch enhancement repair and arthroscopic single row suture in the treatment of large rotator cuff tears.

Methods

A retrospective analysis was conducted on the data of 70 patients with giant rotator cuff tears treated in the Orthopedics Department of Guangzhou Red Cross Hospital affiliated to Jinan University from July 2019 to December 2022. All the patients had rotator cuff tears over five cetimeters or more than two tendons injuries, no local bone lesions, ineffective conservative treatment or poor results, good tolerance to patch repair and good cognitive function. Osteoarthritis,patients who needed complete resection of the distal clavicle, instability in front of the shoulder joint,unauthorized use of drugs or other treatment plans during treatment, end-stage malignant tumors were excluded.According to the treatment method used, the patients were divided into the control group of 35 cases and an observation group of 35 cases. The control group was treated with simple arthroscopic double row suturing, while the observation group was treated with arthroscopic double row suturing combined with allogeneic decellularized dermal patches for enhanced repair. The differences in shoulder joint range of motion, excellent shoulder joint function rate, and total incidence of complications between the two groups were compared by t test and chi square test.

Results

There was no statistically significant difference in shoulder joint range of motion between the two groups before treatment (P>0.05). After treatment, shoulder joint range of motion increased and the observation group were higher than the control group (t=6.820, 5.942, 8.082, 6.624, 7.006, all P<0.05). The excellent rate of shoulder joint function in the observation group was higher than that in the control group (χ2=9.875,P<0.05), and the total incidence of complications was lower than that in the control group (χ2=5.385, P<0.05).

Conclusion

In the treatment of giant rotator cuff tear, allograft acellular dermal patch can improve shoulder joint function and reduce the risk of complications, which is worthy of promotion.
