Abstract

Tendon retraction and fatty degeneration is a major problem in repair of massive rotator cuff tears. Especially in the transosseous refixation technique, a tension-free refixation cannot be obtained in all cases. The purpose of this prospective study was to evaluate the postoperative results using a new tension-free reinsertion technique with a Corkscrew suture anchor system. Thirty patients (25 males, 5 females) with complete one and two tendon tears underwent open rotator cuff repair (rupture of one tendon: n=14, 47%). The torn tendons were mobilized and reinserted medially to reduce tension. Medialization was achieved by inserting tendon near the osteochondral border in a bony trough. The number of implanted suture anchors ranged from 2 to 6 (mean: 3.56). The mean age was 56 years (39-68 years) with a follow-up of 24 months (17-33 months). In one patient physical and sonographic examination showed a complete and in two patients a partial rerupture. A temporarily frozen shoulder occurred in two cases. No infection or rejection response was seen. In no case was revision surgery necessary. No displacement or loosening of the Corkscrew anchors was noticed. The constant score improved from 45 points preoperatively to 85 points at the time of follow-up (mean). The Corkscrew suture anchor system in combination with the new suture technique offers the possibility of a stable reinsertion even in reduced calcified bone structure. This facilitates good conditions for stable fibroblastic healing. Our midterm results show good osseous union combined with a low rerupture rate.
