Comparisons of Retear Patterns for 3 Arthroscopic Rotator Cuff Repair Methods

Abstract

The SBT has a different retear pattern than that of the SRT. However, the K-SBT retear pattern was not different from that of the SRT.

Functional and structural comparisons of the arthroscopic knotless double-row suture bridge and single-row repair for anterosuperior rotator cuff tears

“…6,11 Because the medial row presents the load-bearing part and strangulation of the tendon may occur, modification of the conventional TOE technique by leaving the medial horizontal row untied may be necessary. We agree with Kim et al, 21 who concluded that the knotless double-row suture bridge repair might not only restore the rotator cuff footprint contact area but also reduce tension overload at the suture-tendon interface in the medial row, unlike the conventional TOE repair. Reducing unnecessary tension during repair and developing new techniques that can spread the load placed on the medial row may be important to improving tendonto-bone healing.…”

“…Furthermore, no medial-row knot is created in the current technique, although its benefits on tendon healing are controversial. 21,26 The high incidence of medial cuff failures after the medial-row knot in the conventional TOE repair demonstrates the necessity of taking preventive steps to increase the integrity at the medial row. 6,11 Because the medial row presents the load-bearing part and strangulation of the tendon may occur, modification of the conventional TOE technique by leaving the medial horizontal row untied may be necessary.…”

Footprint Contact Area and Interface Pressure Comparison Between the Knotless and Knot-Tying Transosseous-Equivalent Technique for Rotator Cuff Repair

“…7,8,16 However, although this TOE repair yields comparable or better clinical outcomes and structural integrity, the issue of retearing has not been solved with the TOE technique for cuff repair. [1][2][3][4]17 In addition, several investigators reported an unusual retear configuration of the repaired rotator cuff after TOE repair. 1,2,13 With the conventional single-row repair, many retears occur at the repair site (tendonbone junction).…”

New Retear Pattern after Rotator Cuff Repair at Previous Intact Portion of Rotator Cuff

“…2,3) The suture bridge technique tended to better preserve the cuff tissue repaired at the insertion site of the rotator cuff and give more mechanical strength than the single-row technique. 4) In a systematic review by Hein et al, 1) the rate of retear was lower in the methods of rotator cuff repair using medial row fixation, including double-row technique and suture-bridge technique, than the method using the single-row technique.…”

“…However, not all retears of the rotator cuff were applicable to this classification. 3) Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging (MRI) in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.…”
