Shoulder Angle

Background: The critical shoulder angle (CSA) is the angle created between the superior and inferior bone margins of the glenoid and the most lateral border of the acromion. A few studies recently investigated the relation between CSA and functional outcomes after rotator cuff repair. However, there is a lack of research investigating the effect of CSA on postoperative tendon integrity after rotator cuff repair. Purpose: To assess the effects of the CSA on postoperative tendon integrity after rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who underwent rotator cuff repair for full-thickness supraspinatus tears by 1 senior surgeon between January 2010 and January 2014 were included in this study. All patients had standardized anteroposterior shoulder radiographs the day before surgery. CSA and acromial index (AI) were measured. AI was derived by measuring the distance from the glenoid plane to the lateral border of the acromion and dividing it by the distance from the glenoid plane to the lateral aspect of the humeral head. Functional scores—including American Shoulder and Elbow Surgeons shoulder evaluation form, modified University of California at Los Angeles score, Constant-Murley score, and visual analog scale for pain—were used to evaluate shoulder function at a minimum follow-up of 2 years. Meanwhile, magnetic resonance imaging examinations were performed to evaluate rotator cuff integrity according to the Sugaya method and the signal/noise quotient (SNQ) of the rotator cuff tendon. Results: A total of 90 patients were included in this study: 42 patients with a single-row repair and 48 with a double-row repair. There was a significant positive correlation between CSA or AI and tendon SNQ. On the basis of CSA, the patients were divided into 2 groups: large CSA (>38°) and control (CSA ≤38°). At final follow-up, the large CSA group and the control CSA group demonstrated no significant differences in American Shoulder and Elbow Surgeons, University of California at Los Angeles, Constant, and visual analog scale scores. Postoperative magnetic resonance imaging revealed that the large CSA group had 9 cases of retear, with a significantly higher retear rate than the control group (15% vs 0%, P = .03). Furthermore, the tendon SNQ of the large CSA group was significantly greater than that of the control group. Conclusion: CSA did not appear to influence postoperative functional outcomes, while those in the large CSA group had poor tendon integrity after rotator cuff repair. These findings indicate that a large CSA is associated with an increased risk of rotator cuff tendon retear after repair.

Abstract The critical shoulder angle (CSA) was introduced as a radiological parameter associated with a higher incidence of rotator cuff tears. As a logical consequence, correcting the CSA together with rotator cuff repair should prevent re-tear and provide reliable and good clinical results. We present an all-arthroscopic technique resecting the lateral edge of the acromion (lateral acromioplasty) in order to reduce and correct the CSA after preoperative planning. Preliminary results from 20 patients with an average age of 62 years after rotator cuff repair are reported showing good clinical outcome with a Constant score of 88 points and no re-tear after an average follow-up of 16 months. The CSA was reduced from 39.7° to 32.1°. Previous concerns regarding weakening of the deltoid origin were not confirmed and there were no complications linked to lateral acromioplasty.

Background: Shoulder stiffness is a common complication after arthroscopic rotator cuff repair. However, there is no consensus on the treatment of stiffness after repair. Although one treatment option is an intra-articular steroid injection, it may negatively affect repair integrity, and there is a paucity of literature regarding the timing of intra-articular injections for stiffness after repair and its effect on repair integrity. Purpose: To compare repair integrity and clinical outcomes after an intra-articular steroid injection administered at 6 weeks and 12 weeks postoperatively for shoulder stiffness after arthroscopic rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who developed stiffness after arthroscopic rotator cuff repair were given a series of 3 intra-articular steroid injections every 4 weeks from 6 (6-week group) and 12 weeks (12-week group) postoperatively. The control group had rotator cuff tears but neither stiffness nor injections. Shoulder range of motion (ROM), the Korean Shoulder Scoring System (KSS) score, and the University of California, Los Angeles (UCLA) shoulder score were assessed preoperatively with a minimum of 2-year follow-up. Repair integrity was assessed using magnetic resonance imaging at 6 months postoperatively. Results: Seventy-four of 209 patients (35.4%) who underwent arthroscopic rotator cuff repair developed stiffness. There were no significant differences in retear rates among the 6-week (5.7%, 2/35 patients), 12-week (10.3%, 4/39 patients), and control groups (14.1%, 19/135 patients) ( P = .374). Both the 6- and 12-week groups showed significant improvement in ROM (both P < .001), KSS scores (both P < .001), and UCLA scores (both P < .001) at the final follow-up. The 6-week group showed significantly better ROM ( P < .001), KSS scores ( P < .001), and UCLA scores ( P < .001) than the 12-week group at 3 months postoperatively. However, both the 6- and 12-week groups showed significantly lower KSS (81.3 ± 12.0 [ P = .004] and 83.4 ± 8.6 [ P = .035], respectively) and UCLA (29.3 ± 4.6 [ P = .006] and 30.0 ± 3.3 [ P = .042], respectively) scores than the control group (90.4 ± 13.6 and 32.3 ± 4.7, respectively) at the last follow-up. Conclusion: An intra-articular steroid injection administered at 6 weeks postoperatively for shoulder stiffness after arthroscopic rotator cuff repair may be effective for reducing patients’ pain and improving shoulder ROM at 3 months postoperatively without compromising repair integrity.

Background: Platelet-rich plasma (PRP) has been studied with the objective of reducing the retear rate and improving functional outcomes after rotator cuff repair. Only one study to date has reported its midterm effect. Hypothesis: PRP promotes better functional and structural results in arthroscopic rotator cuff repair. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: All patients underwent arthroscopic single-row repair of small to medium supraspinatus tears. At the end of the surgical procedure, liquid PRP prepared by apheresis with autologous thrombin was applied in the tendon-to-bone interface in the PRP group. The outcomes were assessed by the University of California, Los Angeles (UCLA) and Constant scales and the visual analog scale (VAS) for pain at 6, 12, 24, and 60 months after surgery and magnetic resonance imaging at 12 and 60 months. Results: Of 54 patients initially randomized, we analyzed the clinical outcomes in 51 (25 control, 26 PRP) and the structural outcomes in 44 (22 each group). At 60-month follow-up, the mean UCLA scores were 32.5 ± 3.8 and 32.1 ± 4.6 in the control and PRP groups, respectively ( P = .992). The mean Constant scores were 82.0 ± 9.5 in the control group and 82.1 ± 11.0 in the PRP group ( P = .699). The mean VAS scores were 1.4 ± 1.8 and 1.5 ± 2.1 in the control and PRP groups, respectively ( P = .910). None of the clinical assessments at 6, 12, and 24 months in either group produced statistically significant differences, and both groups showed significant improvements throughout the follow-up time in the 3 evaluations ( P < .001). The control group exhibited 1 full-thickness retear (Sugaya type IV) and 11 partial-thickness retears (Sugaya type III), while the PRP group had 7 partial-thickness retears (Sugaya type III). The overall number of retears did not differ between groups ( P = .203). Conclusion: PRP obtained by apheresis and applied in liquid form with the addition of thrombin at the end of single-row repair of supraspinatus tears did not promote better clinical or structural results at 60-month follow-up.

Background: Although shoulder function is reported to be generally good after rotator cuff repair, limited knowledge exists regarding which prognostic factors predict functional outcomes. Purpose: To identify pre- and perioperative predictors of functional outcomes after arthroscopic rotator cuff repair. Study Design: Case-control study; Level of evidence, 3. Methods: A cohort of 733 consecutive patients treated with rotator cuff repair between 2010 and 2014 in a single orthopaedics unit was included. Data were collected prospectively and included pre- and perioperative variables. Univariate and multivariable linear regression analyses were used to predict shoulder function at 2-year follow-up, as measured by the Western Ontario Rotator Cuff Index (WORC). Results: In total, 647 (88%) patients were followed for 25 ± 5 months (mean ± SD; range, 17-66 months). In the multivariable regression model, the adjusted R2 was 0.360, indicating that 36% of the variation in the WORC at final follow-up could be explained by this statistical model. The multivariable linear regression analysis revealed that the strongest positive independent predictors of shoulder function at 2 years were preoperative WORC and Constant-Murley score in the contralateral shoulder. The model also indicated that activities of daily living, age, subacromial decompression, and biceps surgery had independent positive associations with better shoulder function at 2 years. In addition, previous surgery in the ipsilateral or contralateral shoulder, smoking, partial rotator cuff repair, preoperative pain, and atrophy in the infraspinatus were all independent factors negatively associated with shoulder function after 2 years. The overall healing rate of complete repairs per magnetic resonance imaging was 80%. Conclusion: The most important finding of the present study was that the strongest prognostic factors for better WORC at 2-year follow-up were better preoperative WORC and Constant-Murley score in the contralateral shoulder. Although not all the prognostic factors identified in this study are modifiable, they can still be useful for guiding patients in shared decision making with the surgeon. This cohort study shows that if selection of patients is performed properly, it is possible to obtain a successful outcome.

Objectives: Structural failure of rotator cuff repair (RCR) has been reported to occur in 20-94% at one to two-year follow-up with 80% of these failures occurring within three months of surgical intervention. Poor functional outcomes as well as higher rates of retear have been reported in patients with compromised healing potential due to comorbidities such as diabetes, smoking, obesity, and hypercholesterolemia. Augmentation with growth factors and stem cells and/or biologically augmented patches has been shown to decrease re-tear rates. Biologically-augmented patches provide an environment that is conducive for cell and vessel migration. We investigated patient outcomes following RCR plus bovine bioinductive patch augmentation. Methods: A consecutive series of patients (2015-2018) that underwent RCR plus bovine bioinductive patch by a single surgeon were identified. Patients with diabetes, obesity, hypercholesterolemia, and smokers were included. Patients were excluded with revision rotator cuff repairs. Physical exam included shoulder ROM and manual muscle strength. Patients completed DASH, SF-12 physical and mental, VAS pain and patient satisfaction scores to assess postoperative functional outcomes. Paired sample t-tests were used to assess differences before and after surgery (p<0.05). Results: Sixteen patients (5 females, 62.3±14 years of age, BMI 32.3±13.7) that underwent arthroscopic RCR plus bovine bioinductive patch augmentation were included. Twelve patients had symptomatic 50-90% partial tears and four patients had full thickness tears. Average follow-up was 25.8±13.1 months. Mean shoulder flexion increased from 148.8°±17.5° to 164.7°±15.0° (p=0.0097), external rotation at 90° abduction increased from 67.8°±36.4° to 88.4°±3.5° (p=0.0316). No significant changes were seen in internal rotation behind the back (p=0.1750) or shoulder muscle strength measurements (all p>0.4471). Postoperative DASH score was 10.4±12.8, SF-12 physical score was 52.8±5, SF-12 mental score was 54.2±5.6, VAS pain score was 0.56±0.88, and patient satisfaction was 8.5±0.55. There were no complications or clinical failures at average 3-year follow-up. Patients returned to preoperative sports, including tennis, swimming, bowling, and weightlifting at an average of 21.9±14.3 weeks. Conclusions: RCR with bovine bioinductive patch augmentation is a good alternative treatment for patients with multiple comorbidities and partial and full thickness rotator cuff tears yielding high patient satisfaction, no loss of shoulder ROM or strength, good functional outcomes, and return to preoperative sports.

Background: Modern rotator cuff repair techniques demonstrate favorable early and midterm outcomes, but long-term results have yet to be reported. Purpose: To determine 10-year outcomes and survivorship after arthroscopic double-row transosseous-equivalent (TOE) rotator cuff repair. Study Design: Case series; Level of evidence 4. Methods: The primary TOE rotator cuff repair procedure was performed using either a knotted suture bridge or knotless tape bridge technique on a series of patients with 1 to 3 tendon full-thickness rotator cuff tears involving the supraspinatus. Only patients who were 10 years postsurgery were included. Patient-reported outcomes were collected pre- and postoperatively, including American Shoulder and Elbow Surgeons (ASES), 12-Item Short Form Health Survey (SF-12), Single Assessment Numeric Evaluation (SANE), shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and satisfaction. Kaplan-Meier survivorship analysis was performed. Failure was defined as progression to revision surgery. Results: A total of 91 shoulders (56 men, 31 women) were included between October 2005 and December 2009. Mean follow-up was 11.5 years (range, 10.0-14.1 years). Of 91 shoulders, 5 (5.5%) failed and required revision surgery. Patient-reported outcomes for patients who survived were known for 80% (69/86). Outcomes scores at final follow-up were as follows: ASES, 93.1 ± 10.8; SANE, 87.5 ± 14.2; QuickDASH, 11.1 ± 13.5; and SF-12 physical component summary (PCS), 49.2 ± 10.1. There were statistically significant declines in ASES, SANE, and SF-12 PCS from the 5-year to 10-year follow-up, but none of these changes met the minimally clinically important difference threshold. Median satisfaction at final follow-up was 10 (range, 3-10). From this cohort, Kaplan-Meier survivorship demonstrated a 94.4% survival rate at a minimum of 10 years. Conclusion: Arthroscopic TOE rotator cuff repair demonstrates high patient satisfaction and low revision rates at a mean follow-up of 11.5 years. This information may be directly utilized in surgical decision making and preoperative patient counseling regarding the longevity of modern double-row rotator cuff repair.

Background and Objectives: The purpose of this study was to investigate the effects of microcurrent stimulation on pain, shoulder function, and grip strength in patients with rotator cuff repair. Materials and Methods: This randomized single-blind controlled trial was conducted on inpatients of the rehabilitation department, and included 28 patients who underwent rotator cuff repair. Participants were randomly assigned to the experimental group (n = 14), treated with microcurrent stimulation, and the control group (n = 14), treated with false microcurrent stimulation. The microcurrent stimulation administered to the experimental group underwent general physical therapy and microcurrent stimulation three times a week for 4 weeks. Results: Changes in pain, range of motion in shoulder, simple shoulder test, and grip strength were assessed before and after the intervention. Both groups showed a significant decrease in pain and shoulder function (t = 27.412, 22.079, 19.079, and 18.561; p < 0.001), and grip strength showed a significant increase (t = −8.251 and −9.946; p < 0.001). The experimental group that underwent microcurrent stimulation exhibited a significant effect on pain, shoulder function, and grip strength compared with the control group that underwent false microcurrent stimulation (t = −2.17, −2.22, and 2.213; p = 0.039, 0.035, and 0.036). Conclusions: This study confirmed that microcurrent stimulation is effective for the treatment of rotator cuff repair patients.
