Does timing influence rehabilitation outcomes in arthroscopic rotator cuff repair with biceps rerouting? a prospective randomized study. J Shoulder Elbow Surg 2024; 33:1928-1937. [PMID: 38428476 DOI: 10.1016/j.jse.2024.01.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 01/05/2024] [Accepted: 01/08/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND Arthroscopic rotator cuff repair with biceps rerouting (ABR) has emerged as a reliable option for treating large posterosuperior rotator cuff tears (RCTs). This study aims to compare functional and structural outcomes of early vs. delayed motion rehabilitation protocols following ABR. METHODS A total of 101 patients with semirigid, large, posterosuperior RCTs undergoing ABR were randomized into 2 groups: group I (early motion) with 53 patients (34 females, 19 males) and group II (delayed motion) with 48 patients (31 females, 17 males). In group I, the mean age was 63.9 years (range, 46-79), and in group II, it was 65.4 years (range, 43-78). The mean follow-up periods for group I and group II were 16.2 and 15.5 months, respectively. Preoperative and postoperative assessments were conducted at 3, 6, and 12 months, with structural integrity assessed with magnetic resonance imaging at a minimum follow-up of 12 months. Statistical analyses were performed to compare outcomes between the 2 groups. RESULTS Both groups demonstrated significant improvements in visual analog scale score (group I: 4.0-1.6, group II: 3.7-1.4, P = .501), University of California-Los Angeles shoulder score (group I: 21.5-31.4, group II: 22.4-30.6, P = .331), and acromiohumeral interval (group I: 8.2 mm-9.1 mm, group II: 8.6 mm-9.5 mm, P = .412), with no statistically or clinically meaningful differences. Active range of movements (ROM) were not significantly different between groups, except for active forward flexion at 3 months (group I: 140.1°, group II: 119.2°, P = .006), that was not shown to be translated clinically into differences in function or healing between the groups in this study. Notably, retear rates were similar between groups (group I: 22.6%, group II: 20.8%, P = .826). CONCLUSION This study's findings reveal no clinically discernible differences in active range of motion at 1-year follow-up between patients who underwent ABR for semirigid, large, posterosuperior RCTs and were assigned to either early or delayed motion protocols. Notably, the early motion group demonstrated a plateau in maximum range of movement improvement as early as 3 months postsurgery. Based on these results, implementing an early motion protocol is recommended as an effective approach in the postoperative rehabilitation following ABR.

Biomechanical evaluation of double-stranded knot configurations in high-strength sutures and tapes. Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02566-z. [PMID: 38907860 DOI: 10.1007/s00068-024-02566-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Accepted: 05/27/2024] [Indexed: 06/24/2024]
Abstract
PURPOSE Recently, a new dynamic high-strength suture (DC) was introduced, also available in tape form (DT), featuring a salt-infused silicone core attracting water in a fluid environment to preserve tissue approximation. The aims of this study were to (1) assess the influence of securing throw number on knot security of two double-stranded knot configurations (Cow-hitch and Nice-knot) tied with either dynamic (DC and DT) or conventional (FW and ST) high-strength sutures and tapes, and (2) compare the ultimate force and knot slippage of the novel dynamic versus conventional sutures and tapes when used with their minimal number of needed securing throws. METHODS Seven specimens of each FW, ST, DC and DT were considered for tying with Cow-hitch or Nice-knots. The base of these Cow-hitch and Nice-knots was secured with surgeons` knots using 1-3 alternating throws. Tensile tests were conducted under physiologic conditions to evaluate knot slippage, ultimate force at rupture, and minimum number of throws ensuring 100% knot security. RESULTS: For both Cow-hitch and Nice-knots, 100% security was achieved with 2 securing throws for DC, DT, ST, and with 3 securing throws for FW. With these minimum numbers of securing throws, ultimate force was significantly higher for Nice-knots versus Cow-hitch tied with DT (p = 0.001) and slippage was significantly less with Nice-knots versus Cow-hitch tied with DC (p = 0.019). CONCLUSIONS The minimum number of securing throws required to achieve 100% security was 2 with DC, DT and ST for both Cow-hitch and Nice-knots configurations, in contrast to FW where 3 securing throws were needed. With these minimum numbers of securing throws, Nice-knots were associated with significantly higher ultimate forces when using DT and lower slippage with DC versus Cow-hitch knots.

Abstract
At present, the repair patterns for medium-sized supraspinatus tendon tears are double- and single-row repairs. However, the limitations of double-row repair include excessive anchor implantation and incremental surgical cost and time, whereas a deficient tendon-bone contact area exists with single-row repair. The modified double-pulley suture-bridge repair presented in this study is an arthroscopic technique using 3 double-loaded suture anchors combined with a double-pulley technique to form a hybrid repair pattern with a double row as the mainstay and a single row as the supplement. In the treatment of medium-sized tendon tears, the modified double-pulley suture-bridge repair can not only maximize the tendon-bone contact area but also lower the surgical cost and shorten the operative time. The surgical technique is described, including pearls and pitfalls, as well as advantages and disadvantages.

Abstract
PURPOSE The number of seven required throws per knot was previously reported as providing sufficient security against slippage. A novel high-strength suture featuring dynamic tightening may allow for throw number reduction without compromising stability. The aims of this study were to (1) investigate the influence of the throw number and the effect of different ambient conditions on the knot security of two different high-strength sutures, and (2) compare their biomechanical competence. METHODS Two sutures (FiberWire (FW) and DynaCord (DC)) were considered for preparing alternating surgical knots. The specimens were stratified for exposure to different media during biomechanical testing-namely air (dry), saline solution (wet), and fat (fatty-wet). A monotonic tensile ramp loading to failure was applied in each test run. For each suture and ambient condition, seven specimens with three to seven throws each were tested (n = 7), evaluating their slippage and ultimate force to failure. The minimum number of throws preventing suture unraveling was determined for each suture type and condition. RESULTS For each suture type and condition, failure occurred via rupture in all specimens for the following minimum number of throws: FW-dry-7, wet-7, fatty-wet-7; DC-dry-6, wet-4, fatty-wet-5. When applying seven throws, FW demonstrated significantly larger slippage (6.5 ± 2.2 mm) versus DC (3.5 ± 0.4 mm) in wet (p = 0.004) but not in dry and fatty-wet conditions (p ≥ 0.313). CONCLUSIONS The lower number of throws providing knot security of DC versus FW in the more realistic wet and fatty-wet conditions indicates that the novel DC suture may allow to decrease the foreign body volume and save surgical time without compromising the biomechanical competence.

Abstract
Rotator cuff tears are the most common upper extremity condition seen by primary care and orthopaedic surgeons, with a spectrum ranging from tendinopathy to full-thickness tears with arthritic change. Some tears are traumatic, but most rotator cuff problems are degenerative. Not all tears are symptomatic and not all progress, and many patients in whom tears become more extensive do not experience symptom worsening. Hence, a standard algorithm for managing patients is challenging. The pathophysiology of rotator cuff tears is complex and encompasses an interplay between the tendon, bone and muscle. Rotator cuff tears begin as degenerative changes within the tendon, with matrix disorganization and inflammatory changes. Subsequently, tears progress to partial-thickness and then full-thickness tears. Muscle quality, as evidenced by the overall size of the muscle and intramuscular fatty infiltration, also influences symptoms, tear progression and the outcomes of surgery. Treatment depends primarily on symptoms, with non-operative management sufficient for most patients with rotator cuff problems. Modern arthroscopic repair techniques have improved recovery, but outcomes are still limited by a lack of understanding of how to improve tendon to bone healing in many patients.

Abstract
Purpose The purpose of this study is to perform a systematic review of the scientific literature to compare single and double row techniques for rotator cuff tears in terms of functional, pain improvement and structural healing of the tendon. Methods In order to carry out the research, a systematic selection of scientific articles has been made by consulting PubMed and The Cochrane Library databases. The articles included in the present study compare the single-row and double-row techniques, with publication date between 2016 and 2021. Results Diverse results are observed in the UCLA, SST, Constant and ASES assessment scales and in the range of mobility, therefore, the superiority of one technique in terms of functional results is not established. The double row technique may show superiority in the strength variable, although there is a methodological variability in its measurement. The double-row technique may be related to more intense postoperative pain, while the single-row technique to residual shoulder pain. However, the variables strength and pain show non-homogeneous or coincident data. The superiority of the double row repair in the structural healing of the tendon and a lower re-tear rate than the single row technique is established with statistically significant results, being the most homogeneous and coincident studies.

Abstract
Background There is no clinical gold standard for the indications for single-row (SR) versus double-row (DR) repair according to small, large, or massive rotator cuff tear size. Purpose To conduct a meta-analysis to compare the clinical outcomes and retear rates after arthroscopic SR and DR repair for rotator cuff injuries with different tear sizes. Study Design Systematic review; Level of evidence, 3. Methods On the basis of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria, the PubMed, Embase, Cochrane Library databases, Web of Science, China National Knowledge Infrastructure, and China BioMedical Literature database were searched for relevant studies published before November 1, 2021, using the following search terms: "Rotator Cuff Injuries," "Rotator Cuff Tears," "Arthroscopy," "Arthroscopic Surgery," "single-row," and "double-row"; a total of 489 articles were retrieved. Quality evaluation was conducted for all the studies that met the inclusion criteria. This study evaluated the Constant-Murley score, American Shoulder and Elbow Surgeons (ASES) score, University of California, Los Angeles (UCLA) score, and range of motion (ROM) as well as retear rate. A fixed-effects or random-effects model was adopted to calculate the results and assess risk. Results A total of 10 clinical studies were included, with 404 cases of DR and 387 cases of SR. Regarding overall results, DR had better forward elevation ROM (mean difference [MD] = -4.03° [95% CI, -6.00° to -2.06°]; P < .0001; I 2 = 46%) and a lower retear rate (MD = 2.39 [95% CI, 1.40 to 4.08]; P = .001; I 2 = 0%) compared with SR repair. With regard to small tears (<3 cm), there was no noticeable difference on any of the 3 outcome scores between SR and DR. For large rotator cuff tears (≥3 cm), DR repair showed significantly better ASES scores (MD = -3.09 [95% CI, -6.19 to 0.02]; P = .05; I 2 = 73%) and UCLA scores (MD = -1.47 [95% CI, -2.21 to -0.72]; P = .0001; I 2 = 31%) compared with SR repair. Conclusion Our meta-analysis revealed that DR had better UCLA scores, ASES scores, and ROM in forward elevation and lower retear rates. In rotator cuff tears <3 cm, there were no statistical differences in clinical outcome between SR and DR.

Abstract
Background: This study aimed to compare the knotless internal brace technique and the knot-tying suture bridge technique via the medial approach in the treatment of calcific Achilles tendinopathy. Methods: The clinical data of 25 cases of calcific Achilles tendinopathy in which nonoperative treatments had failed were retrospectively collected. All the patients received Achilles tendon debridement and Haglund deformity excision through a medial approach, followed by repair using the knotless internal brace technique or the knot-tying suture bridge technique. Pain was evaluated by using the visual analog scale (VAS). The American Orthopedic Foot and Ankle Score (AOFAS) questionnaire was administered preoperatively and postoperatively. Results: The mean follow-up time was 2.6 (range 2–3.5) years. There were no wound complications and no Achilles tendon ruptures. At 1 year postoperatively, the internal brace group was superior to the suture bridge group in terms of the VAS scores (p = 0.003). However, no differences were noticed between the two groups in either the VAS or the AOFAS scores at 2 years postoperatively. Conclusions: The medial approach in combination with the suture bridge technique was effective in treating calcific Achilles tendinopathy. The knotless internal brace technique involved less pain compared to the knot-tying suture bridge technique only at the early postoperative stage.

Abstract
Rotator cuff (RC) tears are among the most common musculoskeletal disorders and can be associated with pain, weakness, and shoulder dysfunction. In recent years, there have been significant advances with regard to the understanding of rotator cuff disease and its management. With technological improvements and advanced diagnostic modalities, there has been much progress as to improved understanding of the pathology. Similarly, with advanced implant designs and instrumentation, operative techniques have evolved. Furthermore, refinements in postoperative rehabilitation protocols have improved patient outcomes. In this scoping review, we aim to provide an overview of the current knowledge on the treatment of rotator cuff disorders and to highlight recent advances in its management.

Abstract
Background: Arthroscopic transosseous-equivalent (TOE) techniques may offer additional advantages, including a more efficient surgery with a self-reinforcing construct with equivalent clinical results to medial knotted TOE repair for rotator cuff tears (RCTs). Indications: An arthroscopic knotless double-row (DR) rotator cuff repair (RCR) using FiberTak RC anchors for medial row fixation with box configuration may be an appropriate construct for operatively indicated small-to-moderate full-thickness RCTs. Technique: Our modified technique uses TOE repair principles to address RCTs too small for traditional 4.75-mm anchors using medial row fixation and too large to apply a single medial to lateral anchor repair. The patient is placed in a beach chair position. In addition to standard anterior and posterior portals, a lower lateral working portal and a higher posterolateral viewing portal are made. Subsequent to supraspinatus footprint visualization/preparation, two 2.6-mm FiberTak RC anchors each loaded with 1 LabralTape and 1 FiberWire are placed medially. The 4 sets of sutures for one anchor are placed through the rotator cuff tendon together in 1 spot and the process is repeated for the second anchor. One FiberWire from each anchor is then tied extracorporeally and then a double pulley technique is used to compress the medial aspect of the repair at the footprint in a box configuration. Finally, 1 limb of LabralTape from each of the medial anchors along with the corresponding FiberWire is secured through 2 lateral-row 4.75-mm anchors anteriorly and posteriorly to restore the lateral footprint and secure the rotator cuff in TOE box configuration. This modified technique can provide anatomical compression of the rotator cuff tendon at the footprint with additional medial compression achieved by the box configuration while taking advantage of knotless fixation. Results: Postoperatively, a sling is worn for 4 weeks, passive range of motion (ROM) is initiated at 2 weeks, active ROM is begun at 6 weeks, and strengthening at 3 months. Patients may return to full unrestricted activities around 5 to 6 months. Discussion/Conclusion: A modified arthroscopic DR RCR with box configuration is an excellent treatment option for patients with small-to-moderate full-thickness RCT who fail conservative treatment.

Bushnell BD, Connor PM, Harris HW, Ho CP, Trenhaile SW, Abrams JS. Two-year outcomes with a bioinductive collagen implant used in augmentation of arthroscopic repair of full-thickness rotator cuff tears: final results of a prospective multicenter study. J Shoulder Elbow Surg 2022; 31:2532-2541. [PMID: 35788057 DOI: 10.1016/j.jse.2022.05.025] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 05/19/2022] [Accepted: 05/30/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Full-thickness rotator cuff tears (FTRCTs) represent a common shoulder injury that, if untreated, can progress in size, become increasingly painful, and inhibit function. These lesions are often surgically repaired, with double-row arthroscopic repair often preferred for larger tears. Biological augmentation technologies have been developed to improve rates of postoperative radiographic retear and enhance patient-reported outcomes after surgical FTRCT repair. This study sought to confirm that augmented repair with a bioinductive bovine collagen implant results in favorable retear rates and patient outcomes with follow-up to 2 years. METHODS A prospective multicenter cohort study was undertaken to determine the efficacy and safety of augmenting single- or double-row arthroscopic repair of FTRCTs with a bioinductive bovine collagen implant. Of 115 adult patients participating, 66 (57.4%) had medium (1-3-cm) tears and 49 (42.6%) had large (3-5-cm) tears. Magnetic resonance imaging and patient-reported outcomes (American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form [ASES] and Constant-Murley Score [CMS]) were performed and recorded at baseline, 3 months, 1 year, and 2 years. RESULTS Mean duration of follow-up was 2.1 years (range, 1.5-2.9 years). Between baseline and 2-year follow-up, mean total thickness of the supraspinatus tendon increased by 12.5% for medium tears and by 17.1% for large tears. Radiographic retear was noted in 7 of 61 available patients (11.5%) with medium tears, and in 14 of 40 patients (35.0%) with large tears. In both groups, these tears primarily occurred before the 3-month follow-up visit (13 of 21 [61.9%]). Radiographic retear with the supplemented double-row (DR) repair technique was 13.2% overall (12 of 91 DR patients; 11.3% for medium tears and 15.8% for large tears). The minimal clinically important difference was achieved by >90% of patients with both medium and large tears for both ASES and CMS. There were 2 serious adverse events classified by the treating surgeon as being possibly related to the device and/or procedure (1 case of swelling/drainage and 1 case of intermittent pain). Nine patients (7.8%; 4 medium tears and 5 large tears) required reoperation of the index rotator cuff surgery. CONCLUSION Final 2-year data from this study confirm that using this implant in augmentation of arthroscopic double-row repair of FTRCTs provides favorable rates of radiographic retear and substantial functional recovery. The relative safety of the device is also further supported.

Abstract
ZusammenfassungRotatorenmanschettenrupturen gehören zu den häufigsten muskuloskeletalen Erkrankungen und können mit ausgeprägten Schmerzen und Funktionseinschränkungen einhergehen. Für ihre Entstehung ist eine Vielzahl von Faktoren relevant, u. a. die individuelle Anatomie des Akromions. Mit Hilfe der heutigen technischen Möglichkeiten wurde nun festgestellt, dass zusätzlich zu seiner lateralen Ausdehnung auch die sagittale Ausdehnung des Akromions eine Rolle zu spielen scheint. Die bildgebende Darstellung der Rotatorenmanschette (RM) hat von den technischen Fortschritten der letzten Jahrzehnte ebenfalls profitiert. Magnetresonanztomographie (MRT) und MR-Arthrographie werden heute flächendeckend eingesetzt. Letztere bietet die höchste Sensitivität für die Entdeckung selbst kleiner Partialläsionen. Neue Sequenzen und Nachbearbeitungsmöglichkeiten können als hilfreiche tools für die operative Planung eingesetzt werden. Grundsätzlich richtet sich die Behandlung der RM neben der Symptomatik nach der Rupturgenese und -morphologie sowie der erwarteten Gewebequalität des Muskel-Sehnen-Kontinuums. Auch das Gesamtprofil, die Erwartungshaltung und die Rehabilitationsmöglichkeiten des Patienten sind wichtig. Die heutigen operativen Techniken werden durch spannende Entwicklungen der Industrie mitbestimmt, die in den letzten Jahren immer bessere Fadenankersysteme, aber auch Augmentationsmaterialien auf den Markt gebracht hat. Letztere zielen nicht nur auf die mechanische Verstärkung der Sehnenrekonstruktion, sondern auch auf die Optimierung der biologischen Eigenschaften des Konstrukts ab. Hinsichtlich Fixation konnte die biomechanische Forschung zeigen, dass zweireihige oder Suture-Bridge-Fixationen einreihigen oder transossären Fixationen überlegen sind. Diese Überlegenheit im Labor spiegelt sich noch nicht klar in den klinischen Ergebnissen wider, dennoch sind die meisten Chirurgen heute auf diese Technik übergegangen. Was die postoperative Nachbehandlung angeht, stellen jüngste randomisiert-kontrollierte Untersuchungen das Konzept der postoperativen Immobilisation in Abduktion in Frage. Hier scheint das letzte Wort noch nicht gesprochen zu sein.

Abstract
Insertional Achilles tendinopathy represents a chronic degenerative condition affecting the insertion of the Achilles. Surgery is indicated in recalcitrant cases and often involves extensive debridement followed by subsequent repair of the insertion. In the present study, we evaluate the results of knotted and knotless double-row suture systems for Achilles reattachment. Despite the popularity of double-row repairs, there is a relative paucity of clinic data regarding efficacy of the available implants. In a retrospective cohort study, 38 patients (40 Achilles tendons) who received double-row repairs between November 2012 and December 2016 were evaluated. In addition to demographic information, preoperative pain scores and symptom duration were recorded. Perioperative and postoperative records were reviewed, and telephone interviews were conducted to assess patient satisfaction, functional status, postoperative pain, and information regarding surgical complications. At a mean follow-up of 32.5 months, 35 (92.1%) patients reported satisfaction with the outcome. Decreased pain levels were reported in 38 (95%) ankles, with 21 (52.5%) ankles being rated pain-free postoperatively. Of the patients working prior to surgery, 20 (95.2%) were able to return to normal work duties, and all 11 (100%) patients who engaged in sports preoperatively were able to return to the same level of activity. Two patients developed postoperative infections, one of which required operative debridement. No Achilles avulsions were encountered. No significant differences were noted between the 2 operative techniques. Considering the available biomechanical data, along with high patient satisfaction rates and low rate of complications, double-row repair offers a viable option for recalcitrant insertional Achilles tendinopathy.

Abstract
PURPOSE To compare the different interventions described in the literature for the surgical treatment of small and medium complete rotator cuff tears. METHODS A systematic review of randomized controlled trials of small-medium, full-thickness rotator cuff tears published since 2000 was performed. Clinical characteristics, re-tear rates, range of motion (ROM), and patient-reported outcomes (PRO) data were collected. Interventions were compared via arm-based Bayesian network meta-analysis in a random-effects model. Interventions were ranked for each domain (re-tear risk, pain, ROM, and PROs) via surface under the cumulative ranking curves. RESULTS A total of 18 studies comprising 2046 shoulders (47% females, mean age 61 ± 3 years, mean follow-up 21 ± 5 months) were included. Interventions that ranked highest for minimizing re-tear risk included arthroscopic single-row repair (A+SR) or double-row repair (A+DR) with or without platelet-rich plasma (PRP). Open repair and A+SR repair with acromioplasty (ACP) ranked highest for pain relief. Interventions that ranked highest for ROM improvement included open repair, PT, and A+DR with or without ACP. Interventions that ranked highest for PROs included arthroscopic footprint microfracture with or without SR, open repair, and A+SR with or without ACP. CONCLUSIONS Based on a network meta-analysis of level 1 studies, arthroscopic rotator cuff repair with a SR or DR construct demonstrates similar retear rates, PROs, and clinical outcomes. The highest-ranking treatment for minimizing retears was arthroscopic repair with DR constructs and PRP augmentation, although open repair and arthroscopic SR remain reliable options with excellent clinical outcomes. Addition of PRP to DR constructs trended toward a 56% decreased risk of retear as compared to DR repair alone. Although no single treatment emerged superior, several interventions offered excellent clinical improvements in pain, ROM, and PROs that exceeded minimal clinically important difference thresholds. LEVEL OF EVIDENCE I, systematic review and meta-analysis of level I studies.

Statistical Fragility of Single-Row Versus Double-Row Anchoring for Rotator Cuff Repair: A Systematic Review of Comparative Studies. Orthop J Sports Med 2022; 10:23259671221093391. [PMID: 35571970 PMCID: PMC9096204 DOI: 10.1177/23259671221093391] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Accepted: 02/17/2022] [Indexed: 01/08/2023] Open
Abstract
Background: Comparative studies and randomized controlled trials (RCTs) often use the P (probability) value to convey the statistical significance of their findings. P values are an imperfect measure, however, and are vulnerable to a small number of outcome reversals to alter statistical significance. The inclusion of a fragility index (FI) and fragility quotient (FQ) may aid in the interpretation of a study’s statistical strength. Purpose/Hypothesis: The purpose of this study was to examine the statistical stability of studies comparing single-row to double-row rotator cuff repair. It was hypothesized that the findings of these studies would be vulnerable to a small number of outcome event reversals, often fewer than the number of patients lost to follow-up. Study Design: Systematic review; Level of evidence, 3. Methods: We analyzed comparative studies and RCTs on primary single-row versus double-row rotator cuff repair that were published between 2000 and 2021 in 10 leading orthopaedic journals. Statistical significance was defined as a P < .05. The FI for each outcome was determined by the number of event reversals necessary to alter significance. The FQ was calculated by dividing the FI by the respective sample size. Results: Of 4896 studies screened, 22 comparative studies, 10 of which were RCTs, were ultimately included for analysis. A total of 74 outcomes were examined. Overall, the median FI was 2 (interquartile range [IQR], 1-3), and the median FQ was 0.035 (IQR, 0.020-0.057). The mean FI was 2.55 ± 1.29, and the mean FQ was 0.043 ± 0.027. In 64% of outcomes, the FI was less than the number of patients lost to follow-up.) Additionally, 81% of significant outcomes needed just a single outcome reversal to lose their significance. Conclusion: Over half of the studies currently used to guide clinical practice have a number of patients lost to follow-up greater than their FI. The results of these studies should be interpreted within the context of these limitations. Future analyses may benefit from the inclusion of the FI and the FQ in their statistical analyses.

Abstract
BACKGROUND Rotator cuff injuries have traditionally been managed by either single-row or double-row arthroscopic repair techniques. Complex single-row techniques have recently been proposed as a biomechanically stronger alternative treatment option. However, no rigorous meta-analysis has evaluated the effectiveness of complex single-row against double-row repair. This meta-analysis aims to evaluate clinical outcomes in patients with full-thickness rotator cuff injuries treated with both simple and complex single-row, as well as transosseous-equivalent (TOE) double-row procedures. METHODS An up-to-date literature search was performed using the predefined search strategy. All studies that met the inclusion criteria were assessed for methodological quality and included in the meta-analysis. Pain, functional scores, range of motion, and retear rate were all considered in the study. CONCLUSION The results of our meta-analysis suggest that there is no significant difference between complex single-row and TOE double-row procedures in any of the observed outcomes. At this point in time, the available comparative data between simple single-row and TOE double-row repair techniques are limited. Further high-quality studies are required to assess the clinical outcomes and cost-effectiveness of these different techniques.

Abstract
BACKGROUND Ultrasonographic imaging has been widely used as a diagnostic tool for rotator cuff tears. Several studies have explored the changes in rotator cuff tendon morphology after arthroscopic cuff repair; however, none have addressed the fate of sutures. The aim of this study was to determine (1) if the sutures migrate through the tendon during the postoperative healing period in patients who have had arthroscopic rotator cuff repair; (2) if the sutures do migrate, the time point at which it does; and (3) if the quality of the tendon, in terms of tendon stiffness, modulus of elasticity, bursal thickness, and anatomic footprint, affects suture migration. METHODS This was a prospective study involving 21 patients who had primary arthroscopic rotator cuff repair performed by a single surgeon. All patients were assessed at 8 days, 6 weeks, 12 weeks, and 24 weeks postrepair; during each assessment, patients underwent an ultrasonographic examination (using a Siemens ACUSON S3000 ultrasonographic system, following a standardized protocol), where supraspinatus tendon thickness and thickness of tendon tissues below and above the suture were measured. Measurements of anatomic footprint, bursal thickness, tendon stiffness, and modulus of elasticity were obtained to assess tendon quality. RESULTS Of the 21 participants, 14 (67%) had full-thickness tears and 7 (33%) had partial-thickness tears. Between the 12th- and 24th-week follow-up, 2 patients' tendons were found to be not intact. Within the first 12 weeks of the postrepair healing period, the sutures migrated inferiorly, through to the middle of the tendon at the footprint-articular junction (ie, ratio of tendon tissue thickness below the suture to the total tendon thickness = 0.5) (P = .03). The mean anatomic footprint increased from 8.4 ± 1.6 mm to 9.1 ± 1.2 mm between 8 days and 6 weeks (P = .04); bursal thickness decreased during the 24-week period from 1.5 ± 0.9 mm to 0.7 ± 0.4 mm (P = .005); tendon modulus of elasticity increased from 154 ± 75 kPa to 205 ± 96 kPa between 8 days and 24 weeks (P = .05). DISCUSSION This is the first study to investigate suture position and migration post arthroscopic rotator cuff repair. The findings of this study suggest that sutures migrating to the middle of the tendon during the postoperative healing process is a normal phenomenon observed on ultrasonography.

Abstract
Superior capsular reconstruction (SCR) is increasingly considered a "game-changer" for young patients with irreparable rotator cuff tears. Popular graft choices include fascia lata autograft (FLA) and human dermal allograft (HDA), with the latter strongly preferred in North America and Europe. Despite that, there seems to be a general perception that FLAs are associated with better healing rates due to better biology. However, critical analysis of the literature demonstrates abundant limitations that preclude strong conclusions about whether one graft type is optimal. Furthermore, recent studies have demonstrated that HDAs used for SCR have good healing potential and are also associated with generally good short-term clinical outcomes. A clinical pearl is that humeral sided repair failures are not uncommon, and double-row repair techniques should be thoughtfully considered. The main downside of FLAs is the associated donor site morbidity. Given the lack of proven advantage of FLAs, the impetus to move away from the current trend to use HDAs is low.

Abstract
Surgeons must rely on cost and charge data to inform a patient outcome-optimized value-based approach to arthroscopic rotator cuff repairs. Using biologic and regenerative procedures to augment repairs only when necessary and optimizing anchor number are 2 obvious ways surgeons can help control cost of these procedures. Addition of biologics, such as patches and tissue augmentation, nearly doubled the charges for the procedure.

Cost of Arthroscopic Rotator Cuff Repairs Is Primarily Driven by Procedure-Level Factors: A Single-Institution Analysis of an Ambulatory Surgery Center. Arthroscopy 2021; 37:1075-1083.

Abstract
PURPOSE To identify intraoperative drivers of cost associated with arthroscopic rotator cuff repairs (RCRs) through analysis of an institutional database. METHODS This was a single-institution retrospective review of arthroscopic RCRs performed at an ambulatory surgical center between November 2016 and July 2019. Patient-level factors analyzed included age, sex, insurance type (private, Medicare, Medicaid, self-pay, and other government), American Society of Anesthesiologists grade (I, II, III, and missing), and Charlson comorbidity index (0, 1, 2, and ≥3). Procedure-level factors included use of biologics (decellularized dermal allograft or bioinductive healing implant), anesthesia type (regional block, monitored anesthesia care, or general), number of anchors and sutures, additional procedures (biceps tenodesis, distal clavicle resection, subacromial decompression), and operative time. Multivariate linear regression analysis was used to identify factors significantly associated with higher or lower charges. RESULTS A total of 712 arthroscopic RCRs were included. The risk-adjusted operative charges were $19,728 (95% confidence interval $16,543 to $22,913). The above factors predicted nearly 65% of the variability in operative charges. The only patient-level factor significantly associated with lower charges was female sex (- $1,339; P = .002). Procedure-level factors significantly associated with higher charges were use of biologics (+ $17,791; P < .001), concurrent open biceps tenodesis (+ $4,027; P < .001), distal clavicle resection (+ $2,266; P = .039), use of regional block (+ $1,256; P = .004), number of anchors (+ $2,245/anchor; P < .001), and increasing operative time ($26/min). Other factors had no significant association. CONCLUSIONS Procedural factors are the most significant drivers of operative cost in arthroscopic RCRs, such as quantity and type of implants; additional procedures such as biceps tenodesis and distal clavicle resection; and perioperative conditions such as type of anesthesia and total operating room time. Overall, patient-level factors were not shown to correlate well with operative costs, other than lower charges with female sex. LEVEL OF EVIDENCE IV, economic study.

Abstract
» Regardless of recent advances in rotator cuff repair techniques, the rate of unhealed or recurrent rotator cuff tears remains high, with most recurrent rotator cuff tears occurring within the first 6 months after surgery.
» Factors that can negatively affect tendon healing include older age, greater tear size, tendon retraction, and fatty infiltration. However, several clinical features that are often underestimated, including osteoporosis, diabetes, smoking, and hyperlipidemia, have proven to have an important influence on rotator cuff healing.
» Recent meta-analyses that evaluated studies with Level-I and Level-II evidence have shown an overall increase in retear rates after single-row repair compared with double-row repair. However, to our knowledge, there are no Level-I clinical studies comparing different double-row configurations and, to date, no double-row repair technique has proven to be superior to the others.
» The influence of postoperative rotator cuff healing on clinical outcomes is controversial. Although clinical differences may not be apparent in the short term, healed tendons have had better functional outcomes and greater strength in the midterm.
» In general, a period of immobilization for 2 to 4 weeks, depending on tear size, is recommended. Graded supervised rehabilitation has proven to facilitate tendon healing without associated stiffness compared with early unprotected range of motion.

Mobility Assessment of the Supraspinatus in a Porcine Cadaver Model Using a Sensor-Enhanced, Arthroscopic Grasper. Ann Biomed Eng 2020; 49:617-626. [PMID: 32789712 PMCID: PMC7851033 DOI: 10.1007/s10439-020-02572-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 07/14/2020] [Indexed: 12/03/2022]
Abstract
Tendon mobility is highly relevant in rotator cuff surgery. Objective data about rotator cuff mobility is rare. Tendon mobility still needs to be evaluated subjectively by the surgeon. This study aims to establish a porcine animal model for mobility analysis of the supraspinatus. In this context, we introduce a sensor-enhanced, arthroscopic grasper (SEAG) suitable for objective intraoperative measurements of tendon mobility in clinical praxis. Tendon mobility of 15 fresh porcine cadaver shoulders with artificial rotator cuff tears was evaluated using the SEAG. Mobility characteristics (load–displacement curves, maximum load, stiffness) were studied and inter- and intraobserver agreement (intraclass correlation coefficient (ICC)) were tested. Factors with a potential adverse effect (plastic deformation and rigor mortis) were also evaluated. All shoulders showed characteristic reproducible load–displacement curves with a nonlinear part at the start, followed by a linear part. Mean maximum load was 28.6 N ± 12.5. Mean stiffness was 6.0 N/mm ± 2.6. We found substantial interobserver agreement (ICC 0.672) and nearly perfect intraobserver agreement (0.944) for maximum load measurement. Inter- (0.021) and intraobserver (0.774) agreement for stiffness was lower. Plastic deformation and rigor mortis were excluded. The animal model demonstrates reliable and in vivo-like measurements of tendon mobility. The SEAG is a reliable tool for tendon mobility assessment.

Vishwanathan K, Patel R, Talwalkar S. Which Headless Compression Screw Produces the Highest Interfragmentary Compression Force in Scaphoid Fracture? Indian J Orthop 2020; 54:548-564. [PMID: 32850017 PMCID: PMC7429644 DOI: 10.1007/s43465-020-00107-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Accepted: 04/04/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Interfragmentary compression at the fracture site facilitates healing. Headless compression screws used to treat scaphoid fractures can be grouped as shank screws, conical tapered screws and double component screws. There has been no meta-analysis of biomechanical studies to compare interfragmentary compression produced by the above screws. METHODS A computerised search of Pubmed, Embase and OVID database was undertaken to identify the studies. We estimated the weighted mean difference of interfragmentary compression (in Newton) with 95% confidence intervals. Random effects model was selected for meta-analysis. RESULTS The pooled estimate of nine studies demonstrated that conical tapered screw produced significantly higher interfragmentary compression force compared to the shank screw (WMD 19.96, 95% CI 11.2-28.8, p < 0.0001, I 2 = 99%). The pooled estimate of four studies demonstrated that dual component screw produced significantly higher interfragmentary compression force compared to the shank screw (WMD 16.93, 95% CI 12.3-21.6, p < 0.0001, I 2 = 97.7%). The pooled estimate of four studies showed that there was no significant difference in the interfragmentary compression force generated by either conical tapered screw or dual component screw (WMD 3.93, 95% CI - 8.3 to 16.2, p = 0.53, I 2 = 99.7%). There was evidence of minimal publication bias. CONCLUSION Conical tapered screws and dual component screws produced statistically significant higher interfragmentary compression force at the scaphoid fracture site compared to shank screws. There was no difference in the compression force generated by either conical tapered screw or dual component screw.

Abstract
BACKGROUND The persistent incidence of retear despite improvements in techniques led orthopedic surgeons to the application of principles of tissue bioengineering to achieve enhanced repair and functional outcomes. The purpose of this study was to compare clinical and radiologic outcomes of arthroscopic single-row repair augmented with microfracture (SRM) at the greater tuberosity with single-row (SR) and double-row (DR) repair in the treatment of full-thickness rotator cuff tears. MATERIALS AND METHODS This is a retrospective comparative study. A total of 123 patients were enrolled for arthroscopic repair of full-thickness rotator cuff tears, with 40 patients treated by SR, 44 by SRM, and 39 by DR. The minimum follow-up was 2 years. The primary outcome was retear rate, which was detected by magnetic resonance imaging, and the secondary outcome was functional outcome. RESULTS The mean age of the patients was 59.2 years, 58.1 years, and 60.6 years in the SR, SRM, and DR groups, respectively. The retear rate was 33%, 14%, and 36% in the SR, SRM, and DR groups, respectively (P = .045). The SRM group had significantly improved functional outcomes compared with the SR and DR groups in terms of the postoperative Constant score and visual analog scale score (P = .001 and .002, respectively). Delta Constant scores were nonsignificant for retear and intact tendons (P = .137). CONCLUSION SRM has a significantly lower retear rate and better functional outcome than SR and DR repair.

A Prospective Randomized Trial Comparing Suture Bridge and Medially Based Single-Row Rotator Cuff Repair in Medium-Sized Supraspinatus Tears. Arthroscopy 2019; 35:2803-2813. [PMID: 31604496 DOI: 10.1016/j.arthro.2019.05.026] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2019] [Revised: 05/12/2019] [Accepted: 05/12/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare the clinical and imaging outcomes between the suture bridge technique (SB) and the medially based single-row technique (medSR) in patients with 1- to 3-cm tear sizes. METHODS All patients were evaluated preoperatively and postoperatively (at 12 and 24 months) using the modified University of California, Los Angeles scoring system; active range of motion (flexion and external rotation); and a visual analog scale for pain. Healing status was examined by postoperative magnetic resonance imaging. RESULTS Clinical and imaging evaluations were completed by 92 patients at 1-year follow-up and by 74 patients at 2 years. No significant differences were found between the 2 groups across all measures at final follow-up: The University of California, Los Angeles scores were 33.4 points in SB patients and 33.0 points in medSR patients (P = .58); the visual analog scale scores were 6 mm and 7 mm, respectively (P = .38); the active flexion angles were 161° and 159°, respectively (P = .34); and the external rotation angles were 49° and 52°, respectively (P = .37). Retears were observed in 6.5% of SB patients and 2.1% of medSR patients (P = .31). Medial cuff failure was observed only in SB patients (4.3%, 2 cases), whereas incomplete healing (deep-layer retraction pattern) was observed only in medSR patients (8.7%, 4 cases). Neo-tendon regeneration in the medSR group was observed in 93% of patients. CONCLUSIONS This study did not show any significant differences in the clinical outcomes and cuff integrity between the 2 treatment groups at final follow-up; however, medial cuff failure was observed only in the SB group, and incomplete healing was more frequent in the medSR group. One should consider the risk of medial cuff failure and incomplete healing of the repaired cuff before choosing the repair technique for medium-sized supraspinatus tears. LEVEL OF EVIDENCE Level I, therapeutic, prospective, randomized trial.

Abstract
There is substantial evidence indicating that double-row (DR) repair restores
more of the anatomic rotator cuff footprint and is biomechanically superior to
single-row (SR) repair. Transosseous-equivalent (TOE) techniques have shown
biomechanical advantages when compared with traditional DR, including increased
contact at the rotator cuff footprint, higher pressure at the tendon-bone
interface, and increased failure strength. Several meta-analyses of evidence
level 1 and 2 studies have shown a lower rate of failed/incomplete healing when
DR repair was compared with SR repair types. There is some limited evidence that
TOE techniques improve healing rates in large and massive tears as compared with
SR and DR. Overall, most level 1 and 2 studies have failed to prove a
significant difference between SR and DR repairs in terms of clinical outcomes.
However, most studies include only short-term follow-up, minimizing the impact
that the higher rate of retears/failed healing seen with SR repairs can have in
the long term. There are no high-quality clinical studies comparing different DR
configurations, and there are currently not enough clinical data to determine
the functional advantages of various DR technique modifications over one
another. Although numerous biomechanical and clinical studies comparing
different rotator cuff repair techniques have been published in the past decade,
none has achieved universal acceptance. It is essential for the orthopaedic
surgeon to know in detail the available literature to be able to apply the most
appropriate and cost-effective technique in terms of healing and functional
outcomes. This review provides a critical analysis of the comparative
biomechanical and clinical studies among SR, DR, and TOE techniques reported in
the literature in the past decade.

Abstract
BACKGROUND The factors that associate with surgical decisions about repair technique and the number of suture anchors used in rotator cuff repair have not been previously investigated. This study investigated the extent to which patient, surgeon, and surgical factors associate with performing single-row vs. double-row repair technique and ultimately with the number of suture anchors used. METHODS Our institution's prospective surgical cohort was queried for patients undergoing suture anchor repair of superior-posterior rotator cuff tendon tears between February 2015 and August 2017. Exclusion criteria were patients with isolated subscapularis tears, tears that were not repaired, repairs without suture anchors, repairs involving graft augmentation, and repairs by surgeons with fewer than 10 cases. Multivariable statistical modeling was used to investigate associations between patient and surgical factors and the choice of repair technique and number of suture anchors used. RESULTS A total of 925 cases performed by 13 surgeons met inclusion criteria. Tear type (full thickness), tear size (medium, large, and massive), a greater number of torn tendons, repair type (arthroscopic), and surgeon were significantly associated with performing a double-row over a single-row repair. Tear size, a greater number of torn tendons, double-row repair technique, and surgeon were significantly associated with a greater number of anchors used for repair. CONCLUSIONS Our findings suggest that in the absence of data to conclusively support a clinical benefit of one repair technique over another, surgeons' training, experience, and inherent practice patterns become the primary factors that define their surgical methods.
