Setting Of Rotator Cuff Repair Research Articles

Osteoporosis in the setting of rotator cuff repair: A narrative review

Osteoporosis and osteopenia are frequently found in patients undergoing shoulder surgery, especially rotator cuff repair, and it is anticipated that this link will become more common as more elderly people have operations on their shoulders. For orthopedic surgical candidates who are at high risk, preoperative screening may identify those who might benefit from early intervention and prevent any associated adverse events. The major complications include repair failure and revision surgery. Antiresorptive medication preoperatively has shown good results in vivo. However, when used in the clinical setting, the efficacy remains controversial. Surgical management may include repair augmentation and placing the anchors in the posteromedial part of the greater tuberosity. Level of evidence IV.

Current Cellular and Molecular Biology Techniques for the Orthopaedic Surgeon-Scientist.

The past decade has witnessed numerous advances in musculoskeletal medicine that are helping to propel the field forward. From disease gene identification, to the development of CRISPR-Cas9 and its many applications to treat heritable musculoskeletal conditions, to the refinement of single-cell RNA sequencing (scRNA-seq) and its ability to characterize previously undescribed cellular populations, bench research and translational medicine are evolving at a remarkable pace. In parallel with these laboratory techniques, there has been a rapid evolution of the use of biologics within orthopedic surgery, specifically tendon healing in shoulder surgery, exemplified by the use of platelet-rich plasma, scaffolds, and stem cells to improve tendon healing in the setting of rotator cuff repair.

Outcomes of Biceps Tenotomy Versus Tenodesis During Arthroscopic Rotator Cuff Repair: An Analysis of Patients From a Large Multicenter Database.

Background:Studies to date evaluating biceps tenotomy versus tenodesis in the setting of concomitant rotator cuff repair (RCR) have demonstrated relatively equivalent pain and functional outcomes.Hypothesis:It was hypothesized that a significant difference could be demonstrated for pain and functional outcome scores comparing biceps tenotomy versus tenodesis in the setting of RCR if the study was adequately powered.Study Design:Cohort study; Level of evidence, 3.Methods:The Arthrex Surgical Outcomes System database was queried for patients who underwent arthroscopic biceps tenotomy or tenodesis and concomitant RCR between 2013 and 2021; included patients had a minimum of 2 years of follow-up. Outcomes between treatment types were assessed using the American Shoulder and Elbow Surgeons Shoulder (ASES), Single Assessment Numeric Evaluation (SANE), visual analog scale (VAS) for pain, and Veterans RAND 12-Item Health Survey (VR-12) scores preoperatively and at 3 months, 6 months, 1 year, and 2 years postoperatively. Results were stratified by age at surgery (3 groups: <55, 55-65, >65 years) and sex.Results:Overall, 1936 primary RCRs were included for analysis (1537 biceps tenodesis and 399 biceps tenotomy patients). Patients who underwent tenotomy were older and more likely to be female. A greater proportion of female patients aged <55 years and 55 to 65 years received a biceps tenotomy compared with tenodesis (P = .012 and .026, respectively). All scores were comparable between the treatment types preoperatively and at 3 months, 6 months, and 1 year postoperatively. At 2-year follow-up, patients who received a biceps tenodesis had statistically more favorable ASES, SANE, VAS pain, and VR-12 scores (P ≤ .031); however, the differences did not exceed the minimal clinically important difference (MCID) for these measures.Conclusion:Our findings indicate that surgeons are more likely to perform a biceps tenotomy in female and older patients. Biceps tenodesis provided improved pain and functional scores compared with tenotomy at 2-year follow-up; however, the benefit did not exceed previously reported MCID for the outcome scores. Both procedures provided improvement in outcomes; thus, the choice of procedure should be a shared decision between the surgeon and patient.

Measurement of value in rotator cuff repair: patient-level value analysis for the 1-year episode of care.

Rotator cuff repair (RCR) is one of the most common elective orthopedic procedures, with predictable indications, techniques, and outcomes. As a result, this surgical procedure is an ideal choice for studying value. The purpose of this study was to perform patient-level value analysis (PLVA) within the setting of RCR over the 1-year episode of care. Included patients (N = 396) underwent RCR between 2009 and 2016 at a single outpatient orthopedic surgery center. The episode of care was defined as 1-year following surgery. The Western Ontario Rotator Cuff index was collected at both the initial preoperative baseline assessment and the 1-year postoperative mark. The total cost of care was determined using time-driven activity-based costing (TDABC). Both PLVA and provider-level value analysis were performed. The average TDABC cost of care was derived at $5413.78 ± $727.41 (95% confidence interval, $5341.92-$5485.64). At the patient level, arthroscopic isolated supraspinatus tears yielded the highest value coefficient (0.82; analysis-of-variance F test, P = .01). There was a poor correlation between the change in the 1-year Western Ontario Rotator Cuff score and the TDABC cost of care (r2 = 0.03). Provider-level value analysis demonstrated significant variation between the 8 providers evaluated (P < .01). RCR is one of the most common orthopedic procedures, yet the correlations between cost of care and patient outcomes are unknown. PLVA quantifies the ratio of functional improvement to the TDABC-estimated cost of care at the patient level. This is the first study to apply PLVA over the first-year episode of care. With health care transitioning toward value-based delivery, PLVA offers a quantitative tool to measure the value of individual patient care delivery over the entire episode of care.

Is routine distal clavicle resection necessary in rotator cuff repair surgery? A systematic review and meta-analysis.

The objective of the present study was to perform a systematic review and meta-analysis of randomized controlled trials looking at the effect of distal clavicle resection in patients undergoing rotator cuff repair (RCR). A systematic literature search was undertaken to identify randomized controlled trials looking at RCR +/- distal clavicle resection. Primary clinical outcome measures included in the meta-analysis were American Shoulder Elbow Society (ASES) score, pain on visual analogue scale and range of motion in forward elevation. The systematic review identified three studies with a total of 203 participants. Those who underwent distal clavicle resection in conjunction with RCR had worse pain and acromioclavicular joint tenderness at 3-month follow-up. This difference, however, was not observed at the 24-month follow-up. The mean difference (95% confidence interval) for the ASES score was 0.45 (-3.67 to 4.58) and pain on visual analogue scale was - 0.27 (-0.70 to 0.16). Routine distal clavicle resection in the setting of rotator cuff repair does not result in improved outcomes for patients with no difference being observed at 24 months post surgery. The results of our systematic review and meta-analysis do not support routine distal clavicle resection when performing RCR.

Teres Minor Hypertrophy is a Common and Negative Predictor of Outcomes after Rotator Cuff Repair

Objectives:The teres minor has received increased attention in its role as a rotator cuff muscle, particularly in the setting of large infraspinatus tears. Studies have shown that it plays an important beneficial role after total (TSA) and reverse (RSA) shoulder arthroplasty, as well as in maintenance of function in the setting of infraspinatus wasting in patients with large rotator cuff tears. No study, however, has investigated how often teres minor hypertrophy occurs in a population of rotator cuff tears, whether it occurs in the absence of infraspinatus tearing, or whether it is a positive or negative prognostic indicator on outcomes after rotator cuff repair. The purpose of this study was to determine the prevalence of teres minor hypertrophy in a cohort of patients undergoing rotator cuff repair, and to determine its prognostic effect, if any, on outcomes after surgical repair.Methods:Over a 3 year period, all rotator cuff repairs performed in a single practice by 3 American Shoulder and Elbow Society (ASES) member surgeons were collected. One hundered forty-four patients who had preoperative and postoperative (ASES) outcomes (minimum 2 year), and preoperative Magnetic Resonance Imaging (MRI) were included in the study. All MRIs were evaluated for rotator cuff tear tendon involvement, tear size, and Goutallier changes of each muscle. In addition, occupational ratios were determined for the supraspinatus, infraspinatus, and teres minor muscles. Patients were divided into 2 groups, based upon whether they had teres minor hypertrophy or not, based on a previously established definition. A 2 way univariate ANOVA was used to determine the effect of teres minor hypertrophy(tear size by hypertrophy) and Goutallier changes(tear size by fatty infiltration) on ASES change scores(α=0.05)Results:Teres minor hypertrophy was a relatively common finding in this cohort of rotator cuff patients, with 51% of all shoulders demonstrating hypertrophy. Interestingly, in patients without an infraspinatus tear, teres minor hypertrophy was still present in 19/40 (48%) of patients. Teres minor hypertrophy had a significant, negative effect ASES scores after rotator cuff repair in patients with and without infraspinatus tearing, infraspinatus atrophy, and fatty infiltrative changes(P<0.05). In general, the presence of teres minor hypertrophy demonstrated a 15% lower score (Figure 1) than when no hypertrophy was present, and this was consistent across all tear sizes, independent of Goutallier changes.Conclusion:Teres minor hypertrophy is a common finding in the setting of rotator cuff tearing, including in the absence of infraspinatus tearing. Contrary to previous publications, the presence of teres minor hypertrophy in patients with rotator cuff repair does not appear to be protective as a compensatory mechanism. While further study is necessary to determine the mechanism or implication of teres minor hypertrophy in setting of rotator cuff repair, our results show it is not a positive predictor of outcomes following rotator cuff repair.Summary Sentence:The mechanism of teres minor hypertrophy was found to be a negative predictor in rotator cuff repair after pre and post-op measures were collected on patients undergoing cuff repair.

Simultaneous Rotator Cuff Repair and Arthroscopic Biceps Tenodesis Using Lateral Row Anchor

Treatment of concomitant long head of the biceps pathology in the setting of rotator cuff repair is often required. When a tenodesis of the biceps is used, additional anchors and surgical dissection are typically required. This adds additional surgical time, morbidity of additional surgical dissection, and additional anchor load and cost. We describe a novel technique for arthroscopic biceps tenodesis that uses the anterior lateral row anchor of a double-row rotator cuff repair to simultaneously secure the biceps tenodesis and rotator cuff tear. This technique provides a simple, reproducible, cost-effective means of performing a simultaneous biceps tenodesis and double-row rotator cuff repair.
