Tear Completion Versus In Situ Repair for 50% Partial-Thickness Bursal-Side Rotator Cuff Tears: A Biomechanical and Histological Study in an Animal Model

Abstract: Background: Tear completion followed by repair (TCR) and in situ repair (ISR) have been widely used for bursal-side partial-thickness rotator cuff tears (PTRCTs). Both techniques have shown favorable results; however, controversy continues in terms of the best management. Purpose: To compare the histological and biomechanical outcomes of these 2 techniques for 50% partial-thickness bursal-side rotator cuff tear repair in a rabbit model. Study Design: Controlled laboratory study. Methods: A total of 27 rabbits … Show more

“…Interestingly, there have been studies on live animals that seem to show that tear completion and repair of partial-thickness rotator cuff tears provide better healing compared with in situ repair, in rabbits 30 and in rats. 31 We believe that the technique described here represents a reproducible and effective method in addressing small rotator cuff tears in which the bony footprint of the tendon is small, not visible at all, or covered with remnant tendon, and hence medial row anchors are not required.…”

“…After 2 months, 29,34 the biceps rerouting technique was performed in rabbits with chronic IRCT, modified from the reported clinical techniques. 14,16,32 Briefly, the skin and the deltoid were sequentially split through the previous incision, and a large V-shaped defect was exposed when the scar tissue and tagged sutures were removed (Figure 3A).…”
