Objectives: We have developed the superior capsule reconstruction (SCR) technique for surgical treatment of irreparable rotator cuff tears. In these patients, SCR restores shoulder stability and muscle balance, consequently improving shoulder function—particularly deltoid muscle function—and relieving pain. In this study, we evaluated whether arthroscopic SCR reversed preoperative pseudoparalysis in patients with irreparable rotator cuff tears. Methods: A series of 100 consecutive patients with irreparable rotator cuff tears that had failed conservative treatment underwent arthroscopic SCR using fascia lata autografts; 7 patients with deltoid weakness due to cervical or axillary nerve palsy and 3 patients with severe shoulder stiffness (passive shoulder elevation, less than 90°) before surgery were excluded from the study population. The remaining 90 patients were allocated into 3 groups according to their preoperative active shoulder elevation: (1) no pseudoparalysis: more than 90° of active shoulder elevation (48 patients; mean age, 66.3 years; mean tear size in anterioposterior direction, 3.5 cm); (2) moderate pseudoparalysis: no shoulder stiffness, less than 90° of active shoulder elevation, patients maintained more than 90° elevation once the shoulder was elevated passively (27 patients; mean age, 68.1 years, mean tear size, 3.5 cm); and (3) severe pseudoparalysis: no shoulder stiffness, less than 90° of active shoulder elevation, patients had a positive drop-arm sign (15 patients; mean age, 62.3 years, mean tear size, 4.9 cm). Physical examination, radiography, and magnetic resonance imaging were performed before surgery; at 3, 6, and 12 months after surgery; and yearly thereafter. The American Shoulder and Elbow Surgeons (ASES) score, active shoulder range of motion, acromiohumeral distance, and healing rate were compared between patients with and without pseudoparalysis as well as between before surgery and at the final follow-up (mean, 48 months; range, 24 to 88 months) by using the t and chi-square tests. A significant difference was defined as P < 0.05. Results: ASES score, active elevation, active external rotation, and acromiohumeral distance increased significantly after arthroscopic SCR in patients with no pseudoparalysis, moderate pseudoparalysis, or severe pseudoparalysis. The graft healing rate was 96% (43 of 45) in patients with no pseudoparalysis, 96% (26 of 27) in those with moderate pseudoparalysis, and 87% (13 of 15) in the severe pseudoparalysis group. Postoperative ASES score, active elevation, active external rotation, acromiohumeral distance, and healing rate did not differ among the 3 patient groups. Pseudoparalysis was reversed in 96% (26 of 27) of patients with moderate pseudoparalysis and in 93% (14 of 15) patients with severe pseudoparalysis. Patients with residual moderate or severe pseudoparalysis had graft tears postoperatively. Conclusion: Arthroscopic SCR improved shoulder function and achieved superior stability in patients with previously irreparable rotator cuff tears both with and without pseudoparalysis. Providing that the graft did not tear postoperatively, arthroscopic SCR reversed preoperative pseudoparalysis. The graft healing rate after arthroscopic SCR did not differ between patients with and without pseudoparalysis.

Background: Patients with pseudoparalysis and irreparable rotator cuff tears have very poor function. The authors developed a superior capsule reconstruction (SCR) technique for irreparable rotator cuff tears that restores shoulder stability and muscle balance, improving shoulder function and relieving pain. Purpose: To evaluate whether arthroscopic SCR reversed preoperative pseudoparalysis in patients with irreparable rotator cuff tears. Study Design: Case series; Level of evidence, 4. Methods: One hundred consecutive patients with irreparable rotator cuff tears underwent arthroscopic SCR with fascia lata autografts; 7 patients with deltoid weakness from cervical or axillary nerve palsy and 5 with severe presurgical shoulder stiffness were excluded. The remaining 88 were allocated to 3 groups according to their preoperative active shoulder elevation: no pseudoparalysis (45 patients; mean age, 66.2 years; mean tear size, 3.5 cm), moderate pseudoparalysis (28 patients, 68.3 years, 3.5 cm), and severe pseudoparalysis (15 patients, 62.3 years, 4.9 cm). Clinical outcome, active shoulder range of motion, acromiohumeral distance, and healing rate were compared between patients with and without pseudoparalysis, as well as before surgery and at final follow-up (35-110 months). Results: American Shoulder and Elbow Surgeons score, active elevation, active external rotation, and acromiohumeral distance increased significantly after arthroscopic SCR among all patients. Graft healing rates did not differ among the groups ( P = .73): 98% (44 of 45) for no pseudoparalysis, 96% (27 of 28) for moderate pseudoparalysis, and 87% (13 of 15) for severe pseudoparalysis. Pseudoparalysis was reversed in 96% (27 of 28) of patients with preoperative moderate pseudoparalysis and 93% (14 of 15) with preoperative severe pseudoparalysis. Both patients with residual pseudoparalysis postoperatively (1 of 28 with preoperative moderate pseudoparalysis, 1 of 15 with preoperative severe pseudoparalysis) had graft tears. Conclusion: Arthroscopic SCR restored superior glenohumeral stability and improved shoulder function among patients with or without pseudoparalysis who had previously irreparable rotator cuff tears. In the absence of postoperative graft tear, arthroscopic SCR reversed preoperative pseudoparalysis. Graft healing rates after arthroscopic SCR did not differ between patients with and without pseudoparalysis.

Background: Massive and irreparable rotator cuff tears are difficult to manage surgically. One technique is to use a synthetic polytetrafluoroethylene (PTFE) patch to bridge the tear. However, there is little information regarding the outcomes of this procedure. Purpose: To determine the ≥2-year outcomes of patients for whom synthetic patches were used as tendon substitutes to bridge irreparable rotator cuff defects. Study Design: Case series; Level of evidence, 4. Methods: This retrospective cohort study used prospectively collected data. Patients included those with a synthetic patch inserted as an interposition graft for large and/or irreparable rotator cuff tears with a minimum 2-year follow-up. Standardized assessment of shoulder pain, function, range of motion, and strength was performed preoperatively, at 6 and 12 weeks, and at 6 months and ≥2 years. Radiograph and ultrasound were performed preoperatively, at 6 months, and ≥2 years. Results: At a mean of 36 months, 58 of 68 eligible patients were followed up, and 53 of 58 (90%) patches remained in situ. Three patches failed at the patch-tendon interface, while 1 patient (2 shoulders/patches) went on to have reverse total shoulder replacements. Patient-ranked shoulder stiffness ( P < .001), frequency of pain with activity and sleep ( P < .0001), level of pain at rest and overhead ( P < .0001), and overall shoulder function improved from bad to very good ( P < .0001) by 6 months. Supraspinatus (mean ± SEM: 29 ± 16 N to 42 ± 13 N) and external rotation (39 ± 13 N to 59 ± 15 N) strength were the most notable increases at the ≥2-year follow-up ( P < .0001). Passive range of motion also improved by 49% to 67%; forward flexion, from 131° to 171°; abduction, from 117° to 161°; external rotation, from 38° to 55°; and internal rotation, from L3 to T10 ( P < .0001) preoperatively to ≥2 years. The most improvement in passive range of motion occurred between 12 months and ≥2 years. The mean (SD) Constant-Murley score was 90 (12), while the American Shoulder and Elbow Surgeons score was 95 (8). Conclusion: At 36 months postoperatively, patients who had synthetic patches used as tendon substitutes to bridge irreparable rotator cuff defects reported less pain and greater overall shoulder function as compared with preoperative assessments. They demonstrated improved range of passive motion and improved strength. The data support the hypothesis that the technique of using a synthetic PTFE patch to bridge a large and/or irreparable tear has good construct integrity and improves patient and clinical outcomes.

The functional outcome of 22 consecutive patients with full-thickness rotator cuff tears repaired using an arthroscopically assisted technique was evaluated. The average follow-up was 39 months (24 to 80), and the average tear size was 3.5 cm (1 to 7). There were 14 men and 8 women, with a mean age of 56 years (29 to 80); 86% of patients (N 19) were satisfied with the results of surgery and 95% (N 21) had improvement of their symptoms. All patients had a statistically significant improvement in pain and active abduction in the scapular plane and in external rotation. Postoperative strength in external rotation and abduction averaged 95% and 97% of the contralateral shoulder, respectively. Preoperative duration of symptoms, strength, age, and tear size were found to be independent predictors of outcome. The average Constant and Murley score was 84 of 100, the average American Shoulder and Elbow Surgeons score was 81 of 100, and the average University of California, Los Angeles, score was 31 of 35. Our results show that an arthroscopically assisted repair of full-thickness, moderate-to-large rotator cuff tears using uniform surgical technique and rehabilitation protocols provides excellent outcome with regard to function, pain, and activities of daily living.

Background: Rotator cuff tears with shoulder stiffness remain a difficult issue. Despite the reported satisfactory results of 1-stage surgery, little information is available regarding the factors that affect clinical outcomes. Purpose/Hypothesis: To evaluate the 1-stage arthroscopic treatment of rotator cuff tears with shoulder stiffness and to present the influence of duration of symptoms (DOS) on postoperative functional outcomes. The hypothesis was that a long preoperative DOS is related to worse functional outcomes. Hypothesis: A long preoperative DOS is related to worse functional outcomes. Study Design: Cohort study; Level of evidence, 2. Methods: A cohort study was performed with consecutive patients who underwent 1-stage surgery between January 2012 and July 2014. Forty-four patients were enrolled in the long DOS group (DOS ≥6 months or LDOS), and 38 were enrolled in the short DOS group (DOS <6 months or SDOS). There were no significant differences in the other variables between the groups. The patients were followed for a mean of 33.8 months, and the functional and radiographic outcomes were compared. Results: Both groups achieved apparent functional postoperative improvements in terms of range of motion, pain, strength, and functional scores ( P < .001 for all). Despite the overall improvements, the patients in the SDOS group had significantly better outcomes according to all functional instruments. The mean postoperative abduction and external rotation at the side in the SDOS group were higher than in the LDOS group (abduction: 162.2° vs 152.8°, respectively [ P = .002]; external rotation: 64.7° vs 56.9°, respectively [ P = .004]). The mean postoperative functional scores in the SDOS group were all higher than in the LDOS group (American Shoulder and Elbow Surgeons [ASES] score: 91.1 vs 81.9, respectively; Constant-Murley score: 76.9 vs 71.8, respectively; Fudan University Shoulder Score [FUSS], 90.6 vs 81.1, respectively), and the mean postoperative visual analog scale (VAS) score for pain in the SDOS group was lower (0.7 vs 1.8, respectively) ( P < .001 for all). The difference in the retear rates was not significant, with 7 retears in the SDOS group and 4 in the LDOS group ( P = .216). Conclusion: One-stage surgery effectively achieved overall improvements. A preoperative DOS of ≥6 months led to poorer functional outcomes, which suggests that surgeons should propose a surgical treatment for this condition before symptoms persist for 6 months.

Background: Few studies have reported on the radiological characteristics and repair integrity of coexistent rotator cuff tears (RCTs) and shoulder stiffness after simultaneous arthroscopic rotator cuff repair and capsular release. Purpose: To evaluate the radiological characteristics and repair integrity of 1-stage arthroscopic surgery of RCTs concomitant with shoulder stiffness. Study Design: Cohort study; Level of evidence, 3. Methods: Among patients who underwent arthroscopic repair of full-thickness RCTs, the stiff group underwent simultaneous capsular release for shoulder stiffness, and the nonstiff group had no stiffness. Symptom duration, prevalence of diabetes, tear size, tendon involvement (type 1, supraspinatus; type 2, supraspinatus and subscapularis; and type 3, supraspinatus and infraspinatus; type 4, supraspinatus, subscapularis, and infraspinatus), and fatty infiltration (Goutallier stages 0-4) were evaluated. A retear was appraised using magnetic resonance imaging, and clinical outcomes were assessed using range of motion, the Korean Shoulder Scoring System (KSS), and the University of California, Los Angeles (UCLA) shoulder score. Results: The stiff group showed a significantly lower retear rate (1/39, 2.6%) than the nonstiff group (47/320, 14.7%) ( P = .043). There were significant differences in symptom duration (7.4 ± 6.6 vs 15.0 ± 23.7 months, respectively; P < .001), mediolateral tear size (18.9 ± 8.9 vs 24.1 ± 12.0 mm, respectively; P = .002), tendon involvement (94.9%, 5.1%, 0.0%, and 0.0% vs 85.3%, 6.9%, 7.8%, and 0.0%, respectively; P = .048), and fatty infiltration of the subscapularis (66.7%, 33.3%, 0.0%, 0.0%, and 0.0% vs 31.9%, 61.3%, 5.6%, 1.3%, and 0.0%, respectively; P < .001) and teres minor (74.4%, 20.5%, 5.1%, 0.0%, and 0.0% vs 47.2%, 48.8%, 3.8%, 0.0%, and 0.3%, respectively; P = .007) between the stiff and nonstiff groups. Preoperatively, the stiff group showed significantly worse forward flexion (95.9° ± 23.6° vs 147.7° ± 4.2°, respectively; P < .001), external rotation (17.4° ± 10.1° vs 51.6° ± 12.1°, respectively; P < .001), and internal rotation (L5 vs L2, respectively; P < .001) and lower KSS (52.1 ± 13.8 vs 66.3 ± 13.5, respectively; P < .001) and UCLA scores (18.7 ± 4.8 vs 22.5 ± 4.5, respectively; P < .001) than the nonstiff group. However, these differences became insignificant from 3 months postoperatively for forward flexion ( P > .05) and KSS ( P > .05) and UCLA scores ( P > .05), from 1 year postoperatively for external rotation ( P > .05), and at the last follow-up for internal rotation ( P > .05). A multiple logistic regression analysis revealed that only mediolateral tear size (odds ratio, 1.043; P = .014) and type 2 tendon involvement (odds ratio, 4.493; P = .003) were independent predictors of a retear. Conclusion: RCTs concomitant with shoulder stiffness showed a smaller mediolateral tear size, anterosuperior tendon involvement, and less severe fatty infiltration preoperatively and better repair integrity postoperatively than RCTs without stiffness. Furthermore, the clinical outcomes and range of motion at final follow-up were similar between the 2 groups.

Background: The double-row suture bridge repair was recently introduced and has demonstrated superior biomechanical results and higher yield load compared with the traditional double-row technique. It therefore seemed reasonable to compare this second generation of double-row constructs to the modified single-row double mattress reconstruction. Hypothesis: The repair technique, initial tear size, and tendon subregion will have a significant effect on 3-dimensional (3D) cyclic displacement under additional static external rotation of a modified single-row compared with a double-row rotator cuff repair. Study Design: Controlled laboratory study. Methods: Rotator cuff tears (small to medium: 25 mm; medium to large: 35 mm) were created in 24 human cadaveric shoulders. Rotator cuff repairs were performed as modified single-row or double-row repairs, and cyclic loading (10-60 N, 10-100 N) was applied under 20° of external rotation. Radiostereometric analysis was used to calculate cyclic displacement in the anteroposterior (x), craniocaudal (y), and mediolateral (z) planes with a focus on the repair constructs and the initial tear size. Moreover, differences in cyclic displacement of the anterior compared with the posterior tendon subregions were calculated. Results: Significantly lower cyclic displacement was seen in small to medium tears for the single-row compared with double-row repair at 60 and 100 N in the x plane ( P = .001) and y plane ( P = .001). The results were similar in medium to large tears at 100 N in the x plane ( P = .004). Comparison of 25-mm versus 35-mm tears did not show any statistically significant differences for the single-row repairs. In the double-row repairs, lower gap formation was found for the 35-mm tears ( P ≤ .05). Comparison of the anterior versus posterior tendon subregions revealed a trend toward higher anterior gap formation, although this was statistically not significant. Conclusion: The tested single-row reconstruction achieved superior results in 3D cyclic displacement to the tested double-row repair. Extension of the initial rupture size did not have a negative effect on the biomechanical results of the tested constructs. Clinical Relevance: Single-row repairs with modified suture configurations provide comparable biomechanical strength to double-row repairs. Furthermore, as increased gap formation in the early postoperative period might lead to failure of the construct, a strong anterior fixation and restricted external rotation protocol might be considered in rotator cuff repairs to avoid this problem.

Shoulder Elevation

Pain is routinely implicated as a factor when considering impaired movement in injured populations. Movement velocity is often considered during the rehabilitation process; unfortunately our understanding of pain's impact on shoulder movement velocity in rotator cuff tear patients is less understood. Therefore, the purpose of this study was to test the hypothesis that there would be an increase in peak and mean shoulder elevation velocities following the decrease of shoulder pain in rotator cuff tear patients, regardless of tear size. Fifteen subjects with full-thickness rotator cuff tears (RCT) performed humeral elevation and lowering in three planes before and after receiving a lidocaine injection to relieve pain. Pain was assessed using a visual analog scale. Humeral elevation velocity data were collected using an electromagnetic tracking system. A significant reduction in pain (pre-injection 3.53 ± 1.99; post-injection 1.23 ± 1.43) resulted in significant increases in maximum and mean humeral elevation velocities. Mean shoulder elevation and lowering velocities increased 15.10 ± 2.45% while maximum shoulder movement velocities increased 12.77 ± 3.93%. Furthermore, no significant relationships were noted between tear size and movement velocity. These significant increases in movement velocity provide evidence to further support the notion that human motion can be inhibited by injury-associated pain, and that by reducing that pain through clinical interventions, human movement can be impacted in a positive fashion.

Cuff Repair

Rotator cuff tears are a frequent cause of shoulder pain that often require arthroscopic repair. After surgery an intense and well-studied rehabilitation protocol is needed to obtain the complete recovery of shoulder function. Fifty patients, who sustained arthroscopic rotator cuff repair for symptomatic, atraumatic and full-thickness supraspinatus tendon tear, were involved. According to our rehabilitation protocol, during the first four postoperative weeks, the arm was supported with an abduction sling pillow, and pendulum exercises, table slide and active elbow extension and flexion were conceded. Outcome measures (Oxford shoulder score (OSS), simple shoulder test (SST), patient-reported satisfaction), shoulder function (range of motion (ROM) and muscle strength), and MRI examination were evaluated. The mean OSS score and SST score increased from 16 to 30.2 and from 5.3 to 11.4, respectively. Patient-reported satisfaction was 96%. At 12 months, patients improved ROM and muscle strength. Postoperative passive anterior elevation was 176; external rotation averaged 47; internal rotation was 90. Postoperative muscle strength during anterior elevation was 8.3 ± 2.2 kg, internal rotation 6.8 ± 3 kg, external rotation 5.5 ± 2.3 kg. Five out of seven patients with recurrent tears evaluated their results as satisfactory. They reported improvements in terms of OSS and SST mean scores despite recurrent tears; therefore, they did not undergo revision surgery. The delayed postoperative physical therapy protocol was associated with improvements in the outcome measures and shoulder function compared to the preoperatory state and rotator cuff healing demonstrated by MRI.

Biceps Tenotomy

Background: Lesions of the long head of the biceps tendon are often associated with massive rotator cuff tears (MRCTs), and biceps tenotomy is frequently performed for pain relief and functional reservation. However, the efficacy and safety of biceps tenotomy regarding the effects on the surrounding tissues in chronic MRCT are unclear. Hypothesis: Biceps tenotomy would result in improved mechanical and histological properties of the intact subscapularis tendon and improved in vivo shoulder function while not compromising glenoid cartilage properties. Study Design: Controlled laboratory study. Methods: Right supraspinatus and infraspinatus tendons were detached in 25 male Sprague-Dawley rats, followed by 4 weeks of cage activity to create a chronic MRCT condition. Animals were randomly divided into 2 groups and received either biceps tenotomy (n = 11) or sham surgery (n = 14) and were sacrificed 4 weeks thereafter. Forelimb gait and ground-reaction forces were recorded 1 day before the tendon detachment (baseline), 1 day before the surgical intervention (biceps tenotomy or sham), and 3, 7, 10, 14, 21, and 28 days after the intervention to assess in vivo shoulder joint function. The subscapularis tendon and glenoid cartilage were randomly allocated for mechanical testing or histologic assessment after the sacrifice. Results: Compared with sham surgery, biceps tenotomy partially restored the in vivo shoulder joint function, with several gait and ground-reaction force parameters returning closer to preinjury baseline values at 4 weeks. With biceps tenotomy, mechanical properties of the subscapularis tendons were improved, while mechanical properties and histological Mankin scores of the glenoid cartilage were not diminished when compared with the sham group. Conclusion: Biceps tenotomy in the presence of chronic MRCT partially preserves overall shoulder function and potentially restores subscapularis tendon health without causing detrimental effects to joint cartilage. This laboratory study adds to the growing literature regarding the protective effects of biceps tenotomy on the shoulder joint in a chronic MRCT model. Clinical Relevance: This study provides important basic science evidence supporting the use of biceps tenotomy in patients with massive rotator cuff tears.

Rotator cuff pathology is one of the most common conditions affecting the shoulder joint. Several classification systems have been used to describe rotator cuff tears in orthopedic literature. However, no comprehensive classification inclusive of all types and characteristics currently exists. Rotator cuff tears are classified based on various parameters. These include: 1. Tear depth 2. Tear Size/Extent 3. Tear Retraction 4. Tendon Quality 5. Tear Progression 6. Arthroscopic Classification. This review article aims to establish an algorithm based on the various existing classification systems so as to arrive at the best surgical or non-surgical solution as well as prognosticate the patient regarding the outcome. Special consideration needs to be made for massive tears which are irreparable. Keywords: Rotator cuff tears; Rotator cuff tear classification; Massive irreparable rotator cuff tears; Partial rotator cuff tears; Subscapularis tears; Geometric Classification; Arthroscopic Classification; Rotator cuff retraction; Rotator cuff tendon quality; Prognosis for Rotator Cuff tears.
