Clinical Evaluation of an Arthroscopic Knotless Suprapectoral Biceps Tenodesis Technique: Loop 'n' Tack Tenodesis

Evaluating clinical outcomes of two biceps tenodesis techniques: Loop 'N' Tack and subpectoral biceps tenodesis

Purpose

Biceps tenodesis is an effective surgical procedure that can address pathologies of the long head of the biceps tendon. The purpose of this study was to evaluate clinical outcomes following two different biceps tenodesis techniques: Loop 'N' Tack biceps tenodesis and subpectoral biceps tenodesis.

Hypothesis

Patients undergoing both the subpectoral biceps tenodesis and Loop 'N' Tack biceps tenodesis will have improvements in patient-reported outcomes.

Methods

Hundred and sixty five consecutive patients who underwent biceps tenodesis were retrospectively identified and contacted by phone to collect visual analog scale pain scores, University of California, Los Angeles shoulder scores, Simple Shoulder Test scores, Single Assessment Numeric Evaluation scores, and American Shoulder and Elbow Surgeons scores. Range of motion, elbow flexion strength, and incidence of bicipital groove pain and Popeye deformity were recorded.

Results

One Hundred and forty five patients were included in the study (55 subpectoral, 90 Loop 'N' Tack). Patients in both groups reported high American Shoulder and Elbow Surgeons, Simple Shoulder Test, University of California, Los Angeles, Single Assessment Numeric Evaluation shoulder function scores, low visual analog scale pain scores, and had a minimal risk of complications when measured one year postoperatively.

Conclusion

Loop 'N' Tack biceps tenodesis and subpectoral biceps tenodesis techniques are reliable and effective procedures that can reduce pain scores and restore shoulder function when patients require surgical intervention.

Arthroscopic In Situ Biceps Tenodesis Using a Double Loop-and-Tack Knotless Suture Anchor

The long head biceps tendon is a common culprit of anterior shoulder pain and dysfunction that can be surgically treated with tenotomy or tenodesis. Many techniques exist for tenodesis. This article submits an arthroscopic technique using two loop-and-tack sutures and a knotless suture anchor to tenodese the long head biceps tendon in the proximal bicipital groove in situ. The advantage of this technique is that it maintains the biceps in its native position by performing tenodesis before tenotomy. Most other techniques attempt to restore native position of the biceps through approximation. The transverse humeral ligament is also released to decompress the bicipital groove. This technique can be used to treat isolated biceps pathology or combined with rotator cuff and labral procedures.

Subpectoral Biceps Tenodesis Using an All-Suture Knotless Anchor

The long head of the biceps tendon is a common pain generator in the anterior shoulder and is concomitantly seen with other shoulder pathology including subacromial impingement, as well as rotator cuff and labral tears. This Technical Note describes a mini-open onlay biceps tenodesis technique using all-suture knotless anchor fixation. This technique is easily reproducible, is efficient, and offers the unique benefits of providing a consistent length-tension relation and mitigating the risk of peri-implant reaction and fracture without sacrificing strength of fixation.

Depressive and Anxiety Disorders Increase Risk for Recurrent Anterior Shoulder Pain Following Arthroscopic Suprapectoral Biceps Tenodesis

Purpose

To evaluate factors associated with postoperative anterior shoulder pain following arthroscopic suprapectoral biceps tenodesis (ABT) and to determine the clinical impact of postoperative anterior shoulder pain.

Methods

A retrospective study of patients that underwent ABT between 2016 and 2020 was conducted. Groups were categorized by the presence (ASP+) or absence (ASP-) of postoperative anterior shoulder pain. Patient-reported outcomes (American Shoulder and Elbow score [ASES], visual analog scale [VAS] for pain, subjective shoulder value [SSV]), strength, range of motion, and complication rates were analyzed. Differences between continuous and categorical variables were tested with two-sample t-tests and chi-squared or Fisher's exact tests, respectively. Variables collected at different postoperative timepoints were analyzed using mixed models with post hoc comparisons when significant interactions were detected.

Results

A total of 461 (47 ASP+, 414 ASP-) patients were included. A statistically significant lower mean age was observed in the ASP+ group (P < .001). A statistically significant higher prevalence of major depressive disorder (MDD) (P = .03) or any anxiety disorder (P = .002) was observed in the ASP+ group. Prescription medication with psychotropic medications (P = .01) was significantly more prevalent in the ASP+ group. No significant differences were observed in the proportion of individuals reaching the minimal clinical important difference (MCID) for ASES, VAS, or SSV between groups.

Conclusions

A pre-existing diagnosis of major depressive disorder or any anxiety disorder, as well as the use of psychotropic medications was associated with postoperative anterior shoulder pain following ABT. Other factors associated with anterior shoulder pain included younger age, participation in physical therapy before surgery, and lower rate of concomitant rotator cuff repair or subacromial decompression. Although the proportion of individuals reaching MCID did not differ between groups, the presence of anterior shoulder pain after ABT resulted in prolonged recovery, inferior PROs, and a higher incidence of repeat surgical procedures. The decision to perform ABT in patients diagnosed with MDD or anxiety should be carefully considered, given the correlation to postoperative anterior shoulder pain and inferior outcomes.

Level of Evidence

Level III, retrospective case-control study.

Tack-and-Loop Biceps Tenodesis of the Shoulder: Description of Technique

Biceps tenodesis is a commonly performed procedure during shoulder arthroscopy to treat proximal biceps pathology either independently or in combination with rotator cuff repair. Although many studies have suggested that biceps tenotomy produces similar outcomes, biceps tenodesis can provide improved cosmetic results; other studies have suggested improved function for higher-functioning individuals who undergo tenodesis.

The Lark Loop Used for Proximal Biceps Tenodesis: An All-Arthroscopic Technique

Long head of the biceps tendinopathy is a common shoulder problem that is difficult to diagnose and treat. Biceps tenodesis is an effective surgical approach target for long head of the biceps tendon lesions. This article describes an all-arthroscopic proximal biceps tenodesis technique. This technique uses a high-strength suture to construct a tear-resistant loop; fixation is achieved with a suture anchor at the proximal aspect of the intertubercular groove or the greater tuberosity. This tenodesis fixation is simple, with no neurovascular injury or humeral fracture risk. In addition, our technique is cost-effective, with no need for specialty sutures.

The rate and reporting of fracture after biceps tenodesis: A systematic review

BACKGROUND

The purpose of this systematic review was to (1) define the cumulative humerus fracture rate after BT and (2) compare how often fracture rate was reported compared to other complications.

METHODS

A systematic review was performed using the PRISMA guidelines.

RESULTS

39 studies reported complications and 30 reported no complications. Of the 39 studies that reported complications, 5 studies reported fracture after BT (n = 669, cumulative incidence of 0.53%). The overall non-fracture complication rate was 12.9%.

DISCUSSION

Due to the relatively high incidence of fracture, surgeons should ensure that this complication is disclosed to patients undergoing BT.

Early success of the arthroscopic-assisted locked loop suprapectoral biceps tenodesis

Background

There is wide variability in surgical technique for biceps tenodesis. Prior biomechanical studies have demonstrated superior ultimate and fatigue strength with a Krakow-type locked loop when compared with simple suture and lasso-loop configurations; however, this had not yet been clinically studied. The purpose of this study was to assess the short-term results an arthroscopic-assisted locked loop (ALL) suprapectoral biceps tenodesis technique.

Methods

All patients who underwent an ALL suprapectoral biceps tenodesis by a single surgeon from 2012 and 2019 with a minimum of 12-month follow-up were analyzed. Data collected included demographics, surgical indications, concomitant operative procedures, and postoperative complications of anterior shoulder "groove" pain, "Popeye deformity," biceps muscle cramping pain, and need for revision surgery.

Results

Forty patients who underwent an ALL suprapectoral biceps tenodesis met inclusion criteria. Patients were 55.6 ± 8.6 years of age, consisting of 28 men (57%) and 21 women (43%). The median follow-up was 19.3 months. At the latest follow-up, 1 (2%) patient had anterior shoulder "groove" pain, and no patients had a Popeye deformity or biceps muscle cramping. There were no revision biceps tenodesis procedures.

Conclusion

The ALL suprapectoral biceps tenodesis technique results in a low incidence of postoperative complications. At a short-term follow-up of 1 year, no patients had reoperations or revisions for failed biceps tenodesis. Groove pain was nearly absent in this series of patients.

Biceps Box Configuration for Superior Capsule Reconstruction of the Glenohumeral Joint Decreases Superior Translation but Not to Native Levels in a Biomechanical Study

Purpose

To quantitatively biomechanically assess superior stability, subacromial contact pressures, and glenohumeral kinematics of an in situ biceps tenodesis and a box-shaped long head of the biceps tendon (LHBT) superior capsule reconstruction (SCR) in a superior massive rotator cuff tear (MCT) model.

Methods

Eight cadaveric shoulders (mean age, 62 years; range, 46-70 years) were tested with a custom testing system used to evaluate range of motion, superior translation, and subacromial contact pressure at 0°, 20°, and 40° of abduction. Conditions tested included native state, MCT (complete supraspinatus and one-half of the infraspinatus), a box-shaped LHBT SCR, and an in situ biceps tenodesis. The box-shaped SCR was performed by maintaining the biceps origin, securing 2 corners to the greater tuberosity, and one corner to the posterior glenoid. The in situ tenodesis was performed anatomically at the top of the articular margin in the same shoulder after take-down of the box SCR.

Results

Range of motion was not impaired with either repair construct (P > .05). The box SCR decreased superior translation by approximately 2 mm compared with the MCT at 0°, but translation remained greater compared with the intact state in nearly every testing position. The in situ tenodesis had no effect on superior translation. Peak subacromial contact pressure was increased in the MCT at 0° and 20° abduction compared with the native state but not different between the native and box SCR at the same positions.

Conclusions

A box-shaped SCR using the native biceps tendon partially restores increased superior translation and peak subacromial contact pressure due to MCT. The technique may have a role in augmentation of an irreparable MCT.

Clinical Relevance

The box-shaped LHBT SCR technique may have a role in augmentation of an irreparable MCT.

Measurements of Tendon Movement Within the Bicipital Groove After Suprapectoral Intra-articular Biceps Tenodesis in a Cadaveric Model

Background

Lesions of the long head of the biceps can be successfully treated with biceps tenotomy or tenodesis when surgical management is elected. The advantage of a tenodesis is that it prevents the potential development of a cosmetic deformity or cramping muscle pain. Proponents of a subpectoral tenodesis believe that "groove pain" may remain a problem after suprapectoral tenodesis as a result of persistent motion of the tendon within the bicipital groove.

Purpose/Hypothesis

To evaluate the motion of the biceps tendon within the bicipital groove before and after a suprapectoral intra-articular tenodesis. The hypothesis was that there would be minimal to no motion of the biceps tendon within the bicipital groove after tenodesis.

Study Design

Controlled laboratory study.

Methods

Six fresh-frozen cadaveric arms were dissected to expose the long head of the biceps tendon as well as the bicipital groove. Inclinometers and fiducials (optical markers) were used to measure the motions of the scapula, forearm, and biceps tendon through a full range of shoulder and elbow motions. A suprapectoral biceps tenodesis was then performed, and the motions were repeated. The motion of the biceps tendon was quantified as a function of scapular or forearm motion in each plane, both before and after the tenodesis.

Results

There was minimal motion of the native biceps tendon during elbow flexion and extension but significant motion during all planes of scapular motion before tenodesis, with the most motion occurring during shoulder flexion-extension (20.73 ± 8.21 mm). The motion of the biceps tendon after tenodesis was significantly reduced during every plane of scapular motion compared with the native state (P < .01 in all planes of motion), with a maximum motion of only 1.57 mm.

Conclusion

There was a statistically significant reduction in motion of the biceps tendon in all planes of scapular motion after the intra-articular biceps tenodesis. The motion of the biceps tendon within the bicipital groove was essentially eliminated after the suprapectoral biceps tenodesis.

Clinical Relevance

This arthroscopic suprapectoral tenodesis technique can significantly reduce motion of the biceps tendon within the groove in this cadaveric study, possibly reducing the likelihood of groove pain in the clinical setting.

KAToB: Knotless All-Arthroscopic Intraarticular Tenodesis of the Biceps, An Efficient, Simple, Reproducible Technique

Biceps tenodesis is a commonly performed procedure. It can be done using a multitude of fixation methods, at multiple locations, and either open or arthroscopic, with little if any clinical differences in the literature. Yet, many techniques have drawbacks in the risk of complications or in the technical ease. Here we present what we have found to be an efficient, simple, reproducible technique: KAToB, Knotless All-arthroscopic intraarticular Tenodesis of the Biceps using a knotless anchor at the articular margin. This technique minimizes the risk of nerve injury, infection, and fracture; has good clinical outcomes; and has a low rate of failure.

Influence of workers' compensation status on postoperative outcomes in patients following biceps tenodesis: a matched-pair cohort analysis

BACKGROUND AND HYPOTHESIS

Although the literature on the association of workers' compensation (WC) status with negative outcomes after orthopedic surgery is extensive, there is a paucity of evidence on outcomes in WC recipients undergoing biceps tenodesis. We hypothesized that WC patients would report significantly worse outcomes postoperatively on patient-reported outcome measures (PROMs).

METHODS

Functional and health-related quality-of-life PROMs and a visual analog scale score for pain were administered preoperatively and at 12 months postoperatively to consecutive patients undergoing isolated biceps tenodesis between 2014 and 2018 at our institution. Thirty-eight WC patients were matched 1:2 to non-WC patients by age, body mass index, and operative limb. The minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state were calculated for all patients via anchor- and distribution-based methods. Rates of achievement and the likelihood of achievement were determined.

RESULTS

All patients showed significant improvements in all outcome measures (P < .001). WC patients reported inferior postoperative scores on all PROMs examined. WC status significantly predicted a reduced likelihood of achieving substantial clinical benefit for the American Shoulder and Elbow Surgeons score (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.17-0.81; P = .01) and the patient acceptable symptom state (OR, 0.28; 95% CI, 0.12-0.65; P = .003) for the American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score (OR, 0.24; 95% CI, 0.10-0.61; P = .003), Constant-Murley Subjective Assessment (OR, 0.25; 95% CI, 0.08-0.77; P = .016), and visual analog scale pain score (OR, 0.27; 95% CI, 0.16-0.47; P < .001).

CONCLUSION

WC patients reported inferior scores on all postoperative PROMs and demonstrated lower odds of achieving substantial benefit and satisfaction regarding improvements in both function and pain compared with non-WC patients.

Editorial Commentary: Biceps Tenodesis Location May Not Matter: Go High…Go Low…Go Wherever You Want to Go!

Tenodesis of the long head of the biceps tendon has long been a source of dialogue, discussion, debate, and dogma. In general, the shoulder literature has been exhaustive regarding various biceps tenodesis techniques and outcomes, and studies have shown positive clinical outcomes of tenodesis, regardless of location, along the proximal humerus. Fewer studies have evaluated the outcomes of revision tenodesis; however, those that have looked at this have generally found that a revision to a subpectoral tenodesis site is usually quite successful.

The Loop 'N' Tack Biceps Tenodesis: An All-Arthroscopic, Intra-Articular Technique

Tenodesis and tenotomy of the long head of the biceps are treatment options for a wide range of pathologies without clear superior technique or site of fixation. Clinical outcomes comparing numerous techniques for tenotomy versus tenodesis have resulted in similar pain relief; however, tenotomy may result in a cosmetic "Popeye" deformity and fatigue pain. We present a quick, simple, and knotless technique for tenodesis of the long head of the biceps at the proximal aspect of the bicipital grove that can be completed entirely arthroscopically. This technique uses suture to secure a tenotomized proximal biceps tendon to a knotless anchor just proximal to the subscapularis tendon at the proximal biceps groove. The tensionless repair allows the biceps to scar within the biceps groove, thereby reducing subsidence and formation of a "Popeye" deformity and fatigue pain in the biceps seen with tenotomy alone while eliminating the ability to overtension.

Clinical Outcomes of an All-Arthroscopic Biceps Tenodesis Using the Anterolateral Anchor During Concomitant Double-Row Rotator Cuff Repair

Background:

Pathology of the long head of the biceps tendon frequently occurs concomitantly with rotator cuff tears, necessitating a surgical treatment, often in the form of a tenodesis procedure. Many techniques for a tenodesis exist; however, they often require additional implants or a separate incision.

Purpose:

To report an average of 2-year outcomes of an all-arthroscopic biceps tenodesis employing the stay sutures from the anterolateral anchor during concomitant double-row rotator cuff repair (RCR).

Study Design:

Case series; Level of evidence, 4.

Methods:

Data were prospectively collected and retrospectively reviewed for all patients who underwent an all-arthroscopic biceps tenodesis during concomitant double-row RCR by the senior author between January 2014 and May 2018. Patients were included if they underwent this procedure and had baseline preoperative patient-reported outcomes (PROs) with a minimum of 1 year of postoperative PROs for the American Shoulder and Elbow Surgeons (ASES) score and visual analog scale (VAS) for pain score. Additionally, patient data, surgical history, postoperative complications, and satisfaction were reported.

Results:

Fifteen patients were eligible for the study. There were 12 (80%) men and 3 (20%) women with a mean age of 50.0 years (range, 35-64 years). The mean follow-up time was 25.2 months (range, 13-63 months). Six of 15 (40%) patients also had an arthroscopic subscapularis repair performed. ASES shoulder scores improved from 37.1 preoperatively to 94.1 postoperatively (P < .001), and VAS scores improved from 6.4 preoperatively to 0.5 postoperatively (P < .001). One patient who underwent concomitant subscapularis repair reported continued anterior groove pain. No patients experienced biceps cramping, developed a deformity, or required a repeat operation at the final follow-up. Overall, 93.3% of the patients reported being highly satisfied with their surgery.

Conclusion:

This study presents the clinical results of an all-arthroscopic technique for concomitant double-row RCR and biceps tenodesis, which resulted in high rates of patient satisfaction and significant improvement in reported shoulder outcome and pain scores. Additionally, this technique offers the potential benefits of avoiding a secondary incision, which may decrease surgical morbidity while also decreasing cost by eliminating the need for an extra, tenodesis-specific implant.

The Loop 'n' Tack Knot: Biomechanical Analysis of a Novel Suture Technique for Proximal Biceps Tenodesis

Background

Secure tendon grasping is critical to the success of any tenodesis procedure. Several techniques currently used for tendon grasping can result in longitudinal splitting of the tendon, causing construct failure and failure of the tenodesis.

Purpose

To compare the Loop 'n' Tack knot as a tendon-grasping technique with other common suture techniques. We investigated the biomechanical strength and mode of failure.

Study Design

Controlled laboratory study.

Methods

Eleven matched pairs of proximal biceps were harvested from fresh-frozen cadaveric shoulders. One tendon from each pair was stitched using 1 of 4 different techniques. The suture techniques evaluated included the Loop 'n' Tack with 2 different types of high-strength nonabsorbable suture, a double half-racking stitch, and a Krakow stitch. Samples were cyclically loaded between 5 and 20 N for 100 cycles, followed by a pull to failure at 33 mm/s.

Results

The Loop 'n' Tack techniques were equivalent to the double half-racking and Krakow techniques for load to ultimate failure (P = .817 and P = .984, respectively). The double half-racking technique was the stiffest construct, which was significantly greater than the second-stiffest group, the Loop 'n' Tack method with both FiberLink suture (P = .012) and SutureTape (P = .002), which had greater stiffness than the Krakow group (P < .001). The most common failure mode for the Loop 'n' Tack stitch was suture breakage compared with the Krakow and double half-racking methods, where the most common mode of failure was suture pullout from the tendon (P < .001).

Conclusion

Biomechanical testing found that the Loop 'n' Tack techniques had similar ultimate load to failure values when compared with the double half-racking and Krakow methods. Mode-of-failure analysis showed that the Loop 'n' Tack construct typically failed by suture breakage, whereas the other techniques failed by suture pullout.

Clinical Relevance

The Loop 'n' Tack technique allows for secure grasping of tissue without the need for externalization of the tendon. This technique may be beneficial in compromised or poor-quality tissue without reducing overall pullout strength when compared with a standard half-racking or Krakow stitch.
