RESUMO
PURPOSE: To compare postoperative clinical outcomes at the 3-month, 6-month, 12-month, and latest follow-up in patients undergoing supervised physical therapy (PT) or a home-based exercise program after arthroscopic repair (ARCR) of massive rotator cuff tears (MRCTs). METHODS: A retrospective review was conducted on a prospectively maintained database of patients who underwent either supervised PT or home-based therapy after ARCR of MRCTs between January 2015 and December 2018 at a single center with a minimum 24-month follow-up. At their 2-week postoperative routine follow-up, patients were allowed to choose between home-based and supervised PT. Patient-reported outcomes (PROs) and range of motion (ROM) were collected and compared between cohorts preoperatively and at the 3-month, 6-month, 12-month, and latest follow-up. The percentage of patients reaching or exceeding the minimal clinically important difference (MCID) and patient accepted symptomatic state (PASS) for visual analog scale for pain, American Shoulder and Elbow Surgeon (ASES) score, and Subjective Shoulder Value was recorded for both cohorts at each time point. Complications, healing, satisfaction, and return to work were reported. Healing was evaluated via ultrasound at the latest follow-up. RESULTS: Ninety-nine patients met the study criteria: 61 in the supervised PT cohort and 38 in the home-based cohort. The supervised PT and home-based cohorts returned to the clinic for their most recent follow-up at 53 ± 20 and 55 ± 16 months (P = .496) after surgery, respectively. There was no difference when comparing tendon involvement (supraspinatus, P = .574; infraspinatus, P = .288; subscapularis, P = .592), tear retraction (P = .603), or high-grade fatty infiltration (supraspinatus, P = .684; infraspinatus, P = .397; subscapularis, P = .473) based on preoperative magnetic resonance imaging assessment and surgery-related factors, including anterior (P = .473) or posterior (P = .386) slides, fixation constructs (P = .829), or complete repair (P = .912). Both cohorts showed similar PROs and ROM at baseline. Postoperative PROs and ROM were similar among groups at the 3-month, 6-month, 12-month, and latest follow-up. However, ASES (71.4 vs 61.2; P = .013) and forward flexion (135° vs 118°; P = .023) were significantly higher at 3-month follow-up in the home-based cohort. Both groups comparably achieved MCID and PASS for PROs at the 3-month, 6-month, and 12-month follow-up. At the latest follow-up, the supervised PT and home-based cohort achieved MCID and PASS for visual analog scale (75% vs 81%, P = .573; 70% vs 72%, P = .911), ASES (76% vs 74%, P = .777; 72% vs 72%, P = .873), and Subjective Shoulder Value (82% vs 84%, P = .734; 72% vs 66%, P = .489), respectively. Satisfaction, healing, complication, and return-to-work rates were similar. CONCLUSIONS: Patients undergoing rehabilitation using a home-based protocol showed largely similar functional scores and healing to those with supervised PT after ARCR of MRCTs at the latest follow-up. Although patients with home-based therapy achieved higher forward flexion and ASES at the 3-month follow-up, these became comparable starting at the 6-month postoperative mark. MCID and PASS were achieved similarly for PROs at each time point. LEVEL OF EVIDENCE: Level III, retrospective case series comparison.
RESUMO
BACKGROUND: Glenoid-sided lateralization in reverse shoulder arthroplasty (RSA) decreases bony impingement and improves rotational range of motion, but has been theorized to increase the risk of acromial or scapular spine fractures (ASFs). The purpose of this study was to assess if glenoid-sided lateralization even up to 8 mm increases the risk for stress fracture following RSA with a 135° inlay humeral component. METHODS: A retrospective review was performed from a multicenter prospectively collected database on patients who underwent primary RSA from 2015 to 2021. All RSAs were performed with a 135° inlay humeral component. Varying amounts of glenoid lateralization were used from 0 to 8 mm. Preoperative radiographs were reviewed for the presence of acromial thinning, acromiohumeral distance (AHD), and inclination. Postoperative implant position (distalization, lateralization, and inclination) as well as the presence of ASF was evaluated on minimum 1-year postoperative radiographs. Regression analyses were performed on component and clinical variables to assess for factors predictive of ASF. RESULTS: Acromial or scapular spine fractures were identified in 26 of 470 shoulders (5.5%). Glenoid-sided lateralization was not associated with ASF risk (P = .890). Furthermore, the incidence of fracture did not vary based on glenoid-sided lateralization (0-2 mm, 7.4%; 4 mm, 5.6%; 6 mm, 4.4%; 8 mm, 6.0%; P > .05 for all comparisons). RSA on the dominant extremity was predictive of fracture (odds ratio [OR] 2.21, 95% confidence interval [CI] 1.20-5.75; P = .037), but there was no relationship between patient age, sex, preoperative acromial thinning, or diagnosis and risk of fracture. Although there was no difference in mean postoperative AHD between groups (P = .443), the pre- to postoperative delta AHD was higher in the stress fracture group (2.0 ± 0.7 cm vs. 1.7 ± 0.7 cm; P = .015). For every centimeter increase in delta AHD, there was a 121% increased risk for fracture (OR 2.21, 95% CI 1.33-3.68; P = .012). Additionally, for every 1-mm increase in inferior glenosphere overhang, there was a 19% increase in fracture risk (P = .025). CONCLUSION: Up to 8 mm of glenoid-sided metallic lateralization does not appear to increase the risk of ASF when combined with a 135° inlay humeral implant. Humeral distalization increases the risk of ASF, particularly when there is a larger change between pre- and postoperative AHD or higher inferior glenosphere overhang. In cases of pronounced preoperative superior humeral migration, it may be a consideration to avoid excessive postoperative distalization, but minimizing bony impingement via glenoid-sided lateralization appears to be safe.

BACKGROUND: Optimal glenosphere positioning in a lateralized reverse shoulder arthroplasty (RSA) to maximize functional outcomes has yet to be clearly defined. Center of rotation (COR) measurements have largely relied on anteroposterior radiographs, which allow assessment of lateralization and inferior position, but ignore scapular Y radiographs, which may provide an assessment of the posterior and inferior position relative to the acromion. The purpose of this study was to evaluate the COR in the sagittal plane and assess the effect of glenosphere positioning with functional outcomes using a 135° inlay stem with a lateralized glenoid. METHODS: A retrospective review was performed on a prospectively maintained multicenter database on patients who underwent primary RSA from 2015 to 2021 with a 135° inlay stem. The COR was measured on minimum 2-year postoperative sagittal plain radiographs using a best-fit circle fit method. A best-fit circle was made on the glenosphere and the center was marked. From there, 4 measurements were made: (1) center to the inner cortex of the coracoid, (2) center to the inner cortex of the anterior acromion, (3) center to the inner cortex of the middle acromion, and (4) center to the inner cortex of the posterior acromion. Regression analysis was performed to evaluate any association between the position of the COR relative to bony landmarks with functional outcomes. RESULTS: A total of 136 RSAs met the study criteria. There was no relation with any of the distances with outcome scores (American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, visual analog scale). In regard to range of motion (ROM), each distance had an effect on at least 1 parameter. The COR to coracoid distance had the broadest association with ROM, with improvements in forward flexion (FF), external rotation (ER0), and internal rotation with the arm at 90° (IR90) (P < .001, P = .031, and P < .001, respectively). The COR to coracoid distance was also the only distance to affect the final FF and IR90. For every 1-mm increase in this distance, there was a 1.8° increase in FF and 1.5° increase in IR90 (ß = 1.78, 95% confidence interval [CI] 0.85-2.72, P < .001, and ß = 1.53, 95% CI 0.65-2.41, P < .001; respectively). CONCLUSION: Evaluation of the COR following RSA in the sagittal plane suggests that a posteroinferior glenosphere position may improve ROM when using a 135° inlay humeral component and a lateralized glenoid.
RESUMO
Triceps tendon ruptures are rare but significant injuries that impair upper extremity function. Despite their infrequency, recognizing this condition is crucial due to its severe impact on arm movement and strength. Patients typically present with posterior elbow pain, swelling, and bruising.This report details a complete triceps tendon rupture in a 34-year-old male following trauma. The patient exhibited classic symptoms: posterior elbow pain, significant swelling, and visible bruising, initially suggesting a severe soft tissue injury. Clinical examination and imaging confirmed a complete triceps tendon rupture. This case highlights the importance of considering triceps tendon rupture in patients with similar symptoms, particularly after trauma. Early recognition and accurate diagnosis are essential for timely surgical intervention, significantly improving functional recovery. Delayed diagnosis and treatment can lead to prolonged disability and poor outcomes, emphasizing the need for heightened awareness among healthcare providers regarding this rare but serious injury.
RESUMO
Background: Minimal Clinically Important Difference (MCID) and Patient-Acceptable Symptomatic State (PASS) have emerged as patient-based treatment assessments. However, these have not been investigated in patients undergoing arthroscopic isolated subscapularis repair (AISR). The primary purpose of this study was to determine the MCID and PASS for commonly used patient-reported outcomes in individuals who underwent AISR. The secondary purpose was to assess potential associations between preoperative and intraoperative patient characteristics and the MCID and PASS. Methods: A retrospective analysis was conducted on prospectively collected data for patients who underwent primary AISR between 2011 and 2021 at a single institution, with minimum 2-year postoperative follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and Visual Analog Scale (VAS) pain scale. The MCID was determined using the distribution-based method, while PASS was evaluated using area under the curve analysis. To investigate the relationship between preoperative variables and the achievement of MCID and PASS thresholds, Pearson and Spearman coefficient analyses were employed for continuous and noncontinuous variables, respectively. Results: A total of 77 patients with a mean follow-up of 58.1 months were included in the study. The calculated MCID values for VAS pain, ASES, and SSV were 1.2, 10.2, and 13.2, respectively. The PASS values for VAS pain, ASES, and SSV were 2.1, 68.8, and 68, respectively. There was no significant correlation between tear characteristics and the likelihood of achieving a MCID or PASS. Female sex, worker's compensation status, baseline VAS pain score, and baseline ASES score, exhibited weak negative correlations for achieving PASS for VAS pain and ASES. Conclusion: This study defined the MCID and PASS values for commonly used outcome measures at short-term follow-up in patients undergoing AISR. Tear characteristics do not appear to impact the ability to achieve a MCID or PASS after AISR. Female sex, worker's compensation claim, and low baseline functional scores have weak negative correlations with the achievement of PASS for VAS pain and ASES scores.
RESUMO
IMPORTANCE: Reverse shoulder arthroplasty (RSA) is often used to surgically address massive irreparable rotator cuff tears (MIRCT) without arthritis. The impact of prior attempted rotator cuff repair (RCR) on outcomes is unclear. OBJECTIVE: The purpose of this systematic review was to compare functional outcomes, range of motion, and complications in patients with a MIRCT without arthritis who underwent RSA as a primary procedure versus after prior RCR. EVIDENCE REVIEW: A systematic review was performed on RSA for a MIRCT. The search was conducted from February to March of 2022 using the MEDLINE database. Patient-reported outcome measures (PROs), range of motion (ROM), and complications were extracted. These outcomes were weighted and analysed based on whether the reverse was performed as the primary procedure or following a prior RCR. FINDINGS: Seven studies were included in the analysis, consisting of 343 cases in the primary RSA group and 95 cases in the prior RCR group, with a mean follow-up of 40.8 months. There were no demographic differences between cohorts. Postoperative PROs and ROM were comparable between groups, although the prior RCR group had a higher maximal percentage of improvement (MPI%) for the Constant-Murley Score and Simple Shoulder Test. There was a higher risk for complications (relative risk [RR] 6.26) and revisions (RR 3.91) in the prior RCR group. The most common complications were acromial stress fractures and prosthetic dislocation. CONCLUSION AND RELEVANCE: Patients undergoing RSA for MIRCT following a prior RCR have functional outcomes that are largely comparable to those who have a primary RSA, but they may be at higher risk of complications and revision. LEVEL OF EVIDENCE: IV.

Background: Few studies have reported clinical outcomes and tendon healing rates after arthroscopic isolated subscapularis (SSC) repair (AISR). Purpose/Hypothesis: The primary purpose of this study was to evaluate clinical outcomes and tendon healing after AISR. It was hypothesized that AISR would result in satisfactory clinical outcomes along with a high rate of tendon healing at the midterm follow-up. The secondary purpose was to assess the influence of tear size and muscle atrophy on SSC tendon healing and patient-reported outcomes. It was hypothesized that both would be negatively correlated with healing but would have no effect on clinical outcomes . Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was conducted on prospectively collected data for 77 patients who underwent primary AISR between 2011 and 2021 at a single institution, with a minimum 2-year postoperative follow-up for all patients. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Subjective Shoulder Value (SSV), and the visual analog scale for pain. Repair techniques and concomitant procedures were also collected. SSC tendon healing was evaluated via ultrasound at the final follow-up. Linear regression analysis was performed to determine factors affecting SSC healing. Results: The mean follow-up was 58.1 ± 3.3 months. ASES scores significantly improved from 41.5 to 81.6, and the SSV improved from 38.2 to 80.5 (P < .01 for both). Among the 40 patients (51.9%) who underwent postoperative ultrasound, 87.5% showed complete tendon healing. There were no significant differences in outcome scores between healed and unhealed tendons. Increased muscle atrophy and larger tears were correlated with failure of SSC healing (ß = -0.285 [P = .015] and ß = -0.157 [P = .045], respectively). Conclusion: Improved clinical outcomes and an overall high rate of tendon healing were seen at the midterm follow-up after AISR. Smaller tear sizes with less muscle atrophy were correlated with improved tendon healing. However, even when the tendon incompletely healed, the procedure improved functional outcomes.
RESUMO
Purpose: To investigate the performance of the bear hug (BH) and belly press (BP) tests in diagnosing tears of the subscapularis (SSC). Methods: A retrospective review was conducted on prospectively maintained data on patients who underwent arthroscopic rotator cuff repair (ARCR) of SSC tears between 2011 and 2021. A control group also was obtained of ARCRs with an intact SSC tendon. All examinations and ARCRs were performed by one high-volume shoulder surgeon. The BH test and BP test results were compared with arthroscopic findings as the gold-standard diagnostic modality. Tear type was classified based on the Lafosse classification. Sensitivity, specificity, positive and negative predictive values, false-positive and false-negative rates, and accuracy were calculated for both tests. Results: A total of 1,122 patients were included for analysis, 866 with intraoperatively confirmed SSC tears (77%) and 256 without (23%). The BH test diagnosed SSC tears with a sensitivity of 46.1% and a specificity of 83.2%, whereas the BP test diagnosed tears with a sensitivity of 23.3% and a specificity of 93.4%. Overall, both tests missed SSC tears in 42.3% (n = 475) of cases. The BH test had accuracy rates of 25.9% for SSC type I tear, 48.7% for type II tear, 65% for type III tear, and 81.7% for type IV-V tear. In contrast, the BP test had accuracy rates of 7.6% for type I tear, 14.7% for type II tear, 42% for type III tear, and 68.7% for type IV-V tear. Conclusions: The BH test had greater sensitivity than the BP test in identifying SSC tears. Both tests showed low accuracy in identifying SSC tears as tear size decreased. Combining both tests did not provide any additional benefits over using the BH test alone. Level of Evidence: Level III, diagnostic study.
RESUMO
Purpose: To compare radiologist and surgeon magnetic resonance imaging (MRI) interpretations of subscapularis (SSC) tears against intraoperative arthroscopic examination. Methods: We conducted a retrospective review of prospectively maintained data on patients who underwent arthroscopic rotator cuff repair with and without SSC tears between 2011 and 2022. The radiologists' assessments of SSC integrity were extracted from the MRI reports. One high-volume fellowship-trained shoulder surgeon assessed all MRI scans for the presence or absence of SSC tears. Radiologist and surgeon MRI-based assessments were compared against the diagnostic gold standard (intraoperative arthroscopic examination) and classified according to the Lafosse classification. Sensitivity, specificity, positive and negative predictive values, and accuracy were calculated. Results: A total of 1,090 patients were included for analysis, 839 with intraoperatively confirmed SSC tears (77%) and 251 without such tears (23%). Radiologists diagnosed SSC tears with a sensitivity of 56.0% (470 of 839 patients) and specificity of 67.3% (169 of 251 patients) via MRI, whereas the surgeon diagnosed SSC tears with a sensitivity of 71.4% (599 of 839 patients) and specificity of 78.1% (196 of 251 patients). Overall, radiologists only correctly identified 56% of SSC tears whereas the shoulder surgeon correctly identified approximately 71.4% of tears. When considering arthroscopically confirmed tear size, that is, intact, partial, full thickness [upper border], and complete, the radiologists' diagnosis rates with MRI were 67.3%, 40.4%, 64.6%, and 78.3%, respectively, and the surgeon's diagnosis rates were 78.1%, 52.7%, 81.9%, and 97.5%, respectively. Conclusions: In a community practice, radiologists miss approximately 50% of SSC tears on MRI examination. A shoulder surgeon with the benefit of clinical examination misses 28.6% of tears on MRI. Accuracy increases as tear size increases, with radiologists detecting 40.4% of partial tears and 78.3% of complete tears and a surgeon detecting 52.7% and 97.5%, respectively. Level of Evidence: Level III, diagnostic study (nonconsecutive patients).
RESUMO
BACKGROUND: Previous research has emphasized the effect of prognostic factors on arthroscopic rotator cuff repair (ARCR) success, but a specific focus on subscapularis (SSC) tendon repair healing is lacking. PURPOSE: To identify prognostic factors for SSC healing after ARCR and develop the Subscapularis Healing Index (SSC-HI) by incorporating these factors. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This was a retrospective study using prospectively maintained data collected from patients with isolated or combined SSC tears who underwent ARCR between 2011 and 2021 at a single institution with a minimum 2-year follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and visual analog scale (VAS) pain scale. SSC tendon healing was evaluated via ultrasound at the final follow-up. Multivariate logistic regression analysis was performed to determine the factors affecting SSC healing, and based on these factors, the SSC-HI, which ranges from 0 to 15 points, was developed using odds ratios (ORs). RESULTS: Among 1018 ARCR patients, 931 met the inclusion criteria; 279 returned voluntarily for postoperative SSC ultrasound assessment. The overall healing failure rate was 10.8% (30/279). Risk factors for healing failure included female sex (P = .008; OR, 3.119), body mass index (BMI) ≥30 (P = .053; OR, 2.323), supraspinatus fatty infiltration ≥3 (P = .033; OR, 3.211), lower SSC fatty infiltration ≥2 (P = .037; OR, 3.608), and Lafosse classification ≥3 (P = .007; OR, 3.224). A 15-point scoring system comprised the following: 3 points for female sex, 2 points for BMI ≥30, 3 points for supraspinatus fatty infiltration ≥3, 4 points for lower SSC fatty infiltration ≥2, and 3 points for Lafosse classification ≥3. Patients with ≤4 points had a 4% healing failure rate, while those with ≥9 points had a 55% rate of healing failure. Patients with a healed SSC reported significantly higher ASES (healed SSC: ΔASES, 44.7; unhealed SSC: ΔASES, 29; P < .01) and SSV (healed SSC: ΔSSV, 52.9; unhealed SSC: ΔSSV, 27.5; P < .01) and lower VAS (healed SSC: ΔVAS, -4.2; unhealed SSC: ΔVAS, -3; P < .01) scores compared with those with an unhealed SSC. CONCLUSION: The SSC-HI scoring system integrates clinical and radiological factors to predict SSC healing after surgical repair. Successful SSC healing was found to be associated with enhanced functional outcomes, underscoring the clinical relevance of SSC healing prediction in the management of these tears.
