Abstract

Forty-one patients scheduled for shoulder surgery underwent computed tomography (CT) and magnetic resonance imaging (MRI) examination of their affected shoulder to verify whether fatty degeneration of the rotator cuff muscles could reproducibly be assessed by CT or by MRI and whether the grading with the 2 methods was comparable. In addition, rotator cuff muscle cross-sectional areas were measured on parasagittal MRI scans to establish a possible correlation between rotator cuff muscle atrophy and fatty degeneration. Interobserver reproducibility for grading fatty degeneration was good to excellent for CT and for MRI. The correlation between MRI and CT was fair to moderate and remained unsatisfactory, even if the classification system was simplified with only a 3- rather than a 5-grade scale as originally proposed. The degree of fatty degeneration was significantly related to the amount of atrophy of the respective muscles.

Full arthroscopic vs. arthroscopically assisted posterosuperior latissimus dorsi tendon transfer for shoulders with failed and irreparable rotator cuff repair: matched case-control study
2024, Journal of Shoulder and Elbow Surgery
To compare clinical outcomes and complication rates of full arthroscopic latissimus dorsi tendon transfer (LDTT) vs. arthroscopically assisted LDTT, for the treatment of irreparable posterosuperior massive rotator cuff tears (mRCTs) in shoulders that had failed rotator cuff repair (RCR).
We evaluated a continuous series of 191 patients who underwent LDTT over 4 consecutive years. A total of 107 patients did not have previous shoulder surgery, leaving 84 patients who had prior surgical procedures. All procedures performed over the first 2 years were arthroscopically assisted (n = 48), whereas all procedures performed over the last 2 years were full arthroscopic (n = 36). We noted all complications, as well as clinical scores and range of motion at ≥24 months. To enable direct comparison between the 2 techniques, propensity score matching was used to obtain 2 groups with equivalent age, sex, and follow-up.
Compared with the 48 patients who underwent arthroscopically assisted LDTT, the 36 patients who underwent full arthroscopic LDTT had comparable complications (13% vs. 11%) and conversions to RSA (8.3% vs. 5.6%). Propensity score matching resulted in 2 groups, each comprising 31 patients, which had similar outcomes in terms of clinical scores (except mobility component of Constant score, which was better following fully arthroscopic LDTT; P = .037) and range of motion at a minimum follow-up of 2 years.
At a minimum follow-up of 24 months, for the treatment of irreparable posterosuperior mRCTs in shoulders that had surgical antecedents, full arthroscopic LDTT had significantly better mobility component of the Constant score than arthroscopically assisted LDTT, although there were no significant differences in the other clinical or functional outcomes. Arthroscopically assisted LDTT and full arthroscopic LDTT had comparable rates of complications (8.3% vs. 13%) and conversion to RSA (5.6% vs. 8.3%).
Muscle activation patterns during active external rotation after reverse total shoulder arthroplasty: an electrophysiological study of the teres minor and associated musculature
2024, Journal of Shoulder and Elbow Surgery
Preoperative teres minor insufficiency has been identified as a risk factor for poor restoration of external rotation (ER) after reverse total shoulder arthroplasty (RTSA). However, there has been little investigation regarding muscle activation patterns generating ER. This prospective study sought to determine the timing and activation levels of the shoulder girdle musculature during ER in well-functioning RTSAs with an intact teres minor using a lateralized design.
Patients who underwent RTSA ≥1 year previously with functional ER, an American Shoulder and Elbow Surgeons (ASES) score >70, superior rotator cuff deficiency, and an intact teres minor were identified. Electrophysiological and kinematic analyses were performed during ER in the modified neutral position (arm at side with 90° of elbow flexion) and in abduction (AB) (shoulder abducted 90° with 90° of elbow flexion). Dynamometer-recorded torque and position were pattern matched to electromyography during ER. The root-mean-square and integrated electromyography (in microvolts × milliseconds with standard deviation [SD]), as well as median frequency (MF) (in hertz with SD), were calculated to determine muscle recruitment. Pair-wise t test analysis compared muscle activation (P < .05 indicated significance).
After an a priori power analysis, 16 patients were recruited. The average ASES score, visual analog scale pain score, and ASES subscore for ER in AB (“comb hair”) were 87.7, 0.5, and 2.75 of 3, respectively. In AB, muscle activation began with the upper trapezius, middle trapezius, and latissimus dorsi, followed by the anterior deltoid activating to neutral. With ER beyond neutral, the teres major (9.6 μV × ms; SD, 9.2 μV × ms) initiated ER, followed by the teres minor (14.1 μV × ms; SD, 18.2 μV × ms) and posterior deltoid (11.1 μV × ms; SD, 9.3 μV × ms). MF analysis indicated equal contributions of the teres major (1.1 Hz; SD, 0.5 Hz), teres minor (1.2 Hz; SD, 0.4 Hz), and posterior deltoid (1.1 Hz; SD, 0.4 Hz) in ER beyond neutral. In the modified neutral position, the upper trapezius and middle trapezius were not recruited to the same level as in AB. For ER beyond neutral, the teres major (9.5 μV × ms [SD, 9 μV × ms]; MF, 1.1 Hz [SD, 0.5 Hz]), teres minor (11.4 μV × ms [SD, 15.1 μV × ms]; MF, 1.1 Hz [SD, 0.5 Hz]), and posterior deltoid (8.5 μV × ms [SD, 8 μV × ms]; MF, 1.2 Hz [SD, 0.3 Hz]) were activated in similar sequence and intensity as AB. No differences in muscle activation duration or intensity were noted among the teres major, teres minor, and posterior deltoid (P > .05).
Active ER after RTSA is complex and is not governed by a single muscle-tendon unit. This study establishes a sequence, duration, and intensity of muscle activation for ER in well-functioning RTSAs. In both tested positions, the teres major, teres minor, and posterior deltoid function equally and sequentially to power ER.
Reverse total shoulder arthroplasty with combined latissimus dorsi and teres major transfer in massive irreparable rotator cuff tear with loss of active external rotation: circumferential suturing technique
2024, Seminars in Arthroplasty JSES
Elderly patients with a massive irreparable rotator cuff tear suitable for reverse total shoulder arthroplasty (rTSA), combined with additional loss of active external rotation (ER), experience distress after rTSA alone due to the inability to perform daily tasks that require spatial control of the arm’s position. We hypothesized that performing a combined transfer of Latissimus dorsi (LD) and Teres major (TM) along with rTSA in such patients could lead to improved outcomes after surgery, including those requiring active ER.
This is a retrospective review of 17 patients with a massive irreparable rotator cuff tear and loss of active ER, managed with rTSA and combined LD and TM transfer using a novel circumferential suturing technique. Eleven patients were female, and 6 were male, with a mean age of 73.2 years (ranging from 60 to 82 years). The mean follow-up was 60.5 months. Preoperative and final follow-up clinical and radiological findings were assessed and compared for all patients.
The mean forward flexion (FF) increased from 92° to 137° (P = .001). The mean abduction improved from 94° to 106° (P = .025). The mean ER improved from −14° to 8° (P < .001). The mean range of internal rotation decreased from 4.9 to 4.3 points (thoracolumbar junction to L2) (P = .065). The mean improvement of strength expressed as a percentage of the opposite side was significant for FF, abduction, and ER (P < .001). The mean visual analog scale score for pain improved from 5.5 to 1.7 point (P < .001). The mean University of California at Los Angeles shoulder score increased from 12.6 to 26.7 points (P < .001). The mean Constant Murley shoulder score improved from 40.6 to 75.7 (P < .001). The mean activities of daily living score, which requires active ER, increased from 4.5 to 22.3 points (P < .001). There was a reversal of loss of active ER in 15/17 (88.2%) patients. No perioperative complications related to the tendon transfer and fixation were observed.
The combination of rTSA with LD and TM transfer leads to gains in FF and ER, improving clinical outcomes, including those requiring active ER. Circumferential suturing of LD and TM transfer avoids problems with suture anchors, interference screws, or bone tunnels. The posterodistal attachment site opposite to the original LD insertion is endorsed to mitigate the loss of internal rotation.
Influence of body mass index on severity of rotator cuff tears
2024, Journal of Shoulder and Elbow Surgery
Research on the relationship between obesity and rotator cuff tears (RCTs) has been limited to the impact of obesity on the results of arthroscopic repair of RCTs; thus, a need for rigorous research controlling for other factors affecting RCTs is warranted, especially to better understand the impact of body mass index (BMI) on RCT severity.
A retrospective study of admission records contained in electronic medical records pertaining to patients who were admitted for RCT repair on 1 shoulder between January 2018 and July 2022 was conducted. In total, 386 patients were included. In accordance with guidance regarding obesity from Taiwan's Ministry of Health and Welfare, patients were divided into three groups: underweight or normal weight (BMI <24.0 kg/m²), overweight (BMI 24.0-26.9 kg/m²), or obese (BMI ≥27.0 kg/m²). Magnetic resonance imaging was used to assess RCT severity in terms of four parameters: Patte stage (PS), fatty infiltration (FI), anteroposterior tear size (AP), and retraction size. Multinomial logistic regression analysis was performed on PS and FI grade data, and multiple linear regression analysis was performed on AP tear size and retraction size in order to analyze impact.
Our results revealed that the average age of the 386 patients was 63.41 years (SD = 9.29) and the mean BMI was 25.88 (SD = 3.72) kg/m². We found significant differences in PS (P = .003), FI (P < .001), retraction size (P = .001), and AP tear size (P = .001) among patients who were underweight or normal weight, overweight, and obese. After controlling for other risk factors, including age, gender, RCT-prone occupation, duration of shoulder pain prior to surgery, history of shoulder injury, and tobacco use, we found that obese patients had higher severity levels in PS (B = 1.21, OR = 3.36, P = .029), FI (B = 1.38, OR = 3.96, P < .001), retraction size (β = 0.18, P = .001), and AP tear size (β = 0.18, P = .001) compared to underweight or normal weight patients.
Our study demonstrates that a correlation exists between BMI-measured obesity and RCT severity. We therefore suggest that adults control their weight given that maintaining a healthy weight is highly associated with better shoulder health.
The Combined Suture Bridge With Mason-Allen Technique Is Superior to the Conventional Suture Bridge Technique for Arthroscopic Rotator Cuff Repair
2024, Arthroscopy - Journal of Arthroscopic and Related Surgery
To compare clinical results and retear rates between the combined suture bridge with Mason-Allen (SBMA) technique and the conventional suture bridge (SB) technique in patients with full-thickness rotator cuff tears who underwent arthroscopic rotator cuff repair.
One hundred two patients who underwent arthroscopic rotator cuff repair using the SB technique (n = 50) or SBMA technique (n = 52) for a full-thickness rotator cuff tear and had at least 2 years of follow-up were retrospectively analyzed. Magnetic resonance imaging was performed before surgery and 2 years after to determine preoperative tear size, Goutallier stage, and presence of retear after surgery. Patients were clinically evaluated using the Japanese Orthopaedic Association (JOA) score.
The groups did not significantly differ in terms of follow-up period, age, sex, tear size, Goutallier stage, or number of suture anchors. The retear rate was significantly lower in the SBMA group (7.7% vs 28.0%; P < .01). The JOA score was significantly higher at last follow-up than before surgery in both groups (P <.01). The JOA score at last follow-up was significantly higher in the SBMA group (P = .02).
Arthroscopic rotator cuff repair using the SBMA technique may provide better clinical and anatomical outcomes than the conventional SB technique.

Comparison of cost, surgical time, and clinical results between arthroscopic transosseous rotator cuff repair with lateral cortical augmentation and arthroscopic transosseous equivalent suture bridge: A propensity score-matched analysis
2024, Journal of Orthopaedic Science
To reduce the healthcare burden, the clinical results of arthroscopic rotator cuff repair and the cost of the implants used have recently been focused upon. This study compared implant cost, surgical time, short-term clinical results, and cuff repair integrity 2 years postoperatively between arthroscopic transosseous rotator cuff repair using lateral cortical augmentation (TOA) and arthroscopic transosseous-equivalent suture bridge (TOE).
This study included 220 patients with rotator cuff repairs performed by a single surgeon between December 2013 and December 2018. Overall, 70 TOA and 68 TOE cases met the inclusion criteria. The same surgeon performed the procedures at two different hospitals, and the techniques differed between the facilities. A total of 42 TOA patients were matched with 42 TOE patients. The patients were matched using a propensity score analysis by gender, age, and cuff tear size. The minimum follow-up period was 2 years. Implant cost and surgical time were compared between the two methods. The range of motion, clinical outcomes, and visual analog scale were evaluated. Magnetic resonance imaging was performed to examine cuff repair integrity 2 years postoperatively.
The follow-up rate was 81% (112/138 patients). Implant cost was significantly lower with TOA ($1,396 vs. $2,165; p < 0.001) than with TOE. The average surgical time in the TOA method was significantly shorter than that in the TOE method (82 vs. 109 min; p = 0.001). At a minimum 2-year follow-up, the mean active elevation, abduction, and clinical outcomes improved with both methods, although no improvements in external and internal rotations were observed with either method. There were no significant differences in the postoperative variables and retear rate (TOA, 12%; TOE, 19%; p = 0.548) between the two methods.
TOA and TOE achieved comparable clinical results; however, TOA was more cost-effective and had a shorter surgical time than TOE.
