“…Recent biomechanical studies have demonstrated that the elements for successful repair of a rotator cuff tear are achievement of strong fixation [19–21], a high interface pressure, a wide interface area between the tendon and the bone [22, 23], and minimization of stress concentration inside the tendon [7, 24]. Some new suture techniques allowing achievement of all of these elements have been devised [1, 7].…”

Recently, retear rate after repair for massive cuff tear have been improved through devised suture techniques. However, reported retear rate is relevant to preoperative atrophy and fatty degeneration. The purpose of this study was to investigate whether preoperative atrophy and fatty degeneration of rotator cuff muscles improve by successful repair. Twenty-four patients with massive rotator cuff tear were evaluated on the recovery of atrophy and fatty degeneration of supraspinatus and infraspinatus muscle after surgery. Atrophy was classified by the occupation ratio and fatty degeneration by modified Goutallier's classification. Both were assessed on magnetic resonance imaging (MRI) before and after the operation. When the cuff was well repaired, improvement of the atrophy and fatty degeneration were observed in a half and a one-fourth of the cases, respectively. In retear cases, however, atrophy and fatty degeneration became worse. Improvement of atrophy and fatty degeneration of the rotator cuff muscles may be expected in the cases with successful achievement of rotator cuff repair for large and massive tear.

“…Several biomechanical studies have evaluated the ultimate load-to-failure of various rotator cuff repair constructs. Waltrip et al 21 used cyclic loading to compare single-row and double-row construct strength. In their study, single-row repair with simple sutures failed after a mean of 1414 cycles as compared with the double-row repair, which failed after a mean of 3694 cycles.…”

“…The literature has demonstrated that single- and double-row repairs are safe and effective. [1135] The purpose of this study, unlike prior biomechanical studies that examined the relative strength double-row cuff repair,[1314161718] was to illustrate the kinematic effects of single- and double-row suture anchor repairs of 2 cm supraspinatus tears on simulated active glenohumeral joint kinematics.…”

“…Biomechanical studies have found double-row constructs to be stronger than single-row constructs in both cadaveric[712131415161718] and animal[1920212223] models. In addition, double-row repairs can restore the tendon footprint more accurately[15232425] and are associated with higher rates of tendon healing than single-row repairs.…”

Purpose:Double-row suture anchor fixation of the rotator cuff was developed to reduce repair failure rates. The purpose of this study was to determine the effects of simulated rotator cuff tears and subsequent repairs using single- and double-row suture anchor fixation on three-dimensional shoulder kinematics. It was hypothesized that both single- and double-row repairs would be effective in restoring active intact kinematics of the shoulder.Materials and Methods:Sixteen fresh-frozen cadaveric shoulder specimens (eight matched pairs) were tested using a custom loading apparatus designed to simulate unconstrained motion of the shoulder. In each specimen, the rotator cuff was sectioned to create a medium-sized (2 cm) tear. Within each pair, one specimen was randomized to a single-row suture anchor repair, while the contralateral side underwent a double-row suture anchor repair. Joint kinematics were recorded for intact, torn, and repaired scenarios using an electromagnetic tracking device.Results:Active kinematics confirmed that a medium-sized rotator cuff tear affected glenohumeral kinematics when compared to the intact state. Single- and double-row suture anchor repairs restored the kinematics of the intact specimen.Conclusions:This study illustrates the effects of medium-sized rotator cuff tears and their repairs on active glenohumeral kinematics. No significant difference (P ≥ 0.10) was found between the kinematics of single- and double-row techniques in medium-sized rotator cuff repairs.Clinical Relevance:Determining the relative effects of single- and double-row suture anchor repairs of the rotator cuff will allow physicians to be better equipped to treat patients with rotator cuff disease.

Rotator Cuff Repair

Abstract: The initial fixation strength of our double-layer repair exceeds that of isolated single-layer repairs with either suture anchors or transosseous tunnels.
