Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis

BACKGROUNDRotator cuff pathology is a very common source of shoulder pain. Similarly, osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms. Surgical management can be indicated for both pathologies, however, outcomes data is limited when examining rotator cuff repair (RCR) in the setting of glenohumeral arthritis (GHOA). Thus, this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIMTo evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODSThis was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017. Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity. Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis. Patients included had a minimum two year follow-up. Rate of conversion to total shoulder arthroplasty, complication rates following initial surgery, and patient-reported outcome measures were collected.RESULTSA total of 142 patients were included. The number of patients that required total shoulder arthroplasty within two years after index surgery was low. 2/71 (2.8%) patients with GHOA, and 1/71 (1.4%) without GHOA. Following rotator cuff repair, both groups showed favorable patient-reported outcomes.CONCLUSIONPatients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis.

Trends in rotator cuff surgery: Research through the decades

IntroductionThe aim of this study is to analyse the most cited articles in rotator cuff surgery and identify trends in topics by decade to see which areas may still need further investigationMethodsJournal Citation Index was searched to find articles using the search terms pertaining to “rotator cuff repair”. All articles were ranked according to most cited, and then further analysed to find most cited articles in each decade. Articles were grouped into topics to find themes for each decade.ResultsAll the most cited articles were published in 6 orthopaedic journals. Only 4 of the top 30 citations provided level I evidence. Each decade’s most cited articles seemed to fit into a broad topic, with platelet-rich plasma and biologic augmentation being prominent in the last decade.ConclusionThere are still many unanswered questions in rotator cuff surgery, but this may be because success of certain treatment options are highly dependent on patient selection. Despite growing numbers of articles being published on rotator cuff repairs, the level of evidence remains low. Larger, collaborative projects may help in answering the common dilemmas that still face shoulder surgeons.     

Factors affecting healing after arthroscopic rotator cuff repair

Rotator cuff repair has been shown to have good long-term results. Unfortunately, a significant proportion of repairs still fail to heal. Many factors, both patient and surgeon related, can influence healing after repair. Older age, larger tear size, worse muscle quality, greater muscle-tendon unit retraction, smoking, osteoporosis, diabetes and hypercholesterolemia have all shown to negatively influence tendon healing. Surgeon related factors that can influence healing include repair construct-single vs double row, rehabilitation, and biologics including platelet rich plasma and mesenchymal stem cells. Double-row repairs are biomechanically stronger and have better healing rates compared with single-row repairs although clinical outcomes are equivalent between both constructs. Slower, less aggressive rehabilitation programs have demonstrated improved healing with no negative effect on final range of motion and are therefore recommended after repair of most full thickness tears. Additionally no definitive evidence supports the use of platelet rich plasma or mesenchymal stem cells regarding improvement of healing rates and clinical outcomes. Further research is needed to identify effective biologically directed augmentations that will improve healing rates and clinical outcomes after rotator cuff repair.

Rates of medial and lateral row failure and risk factors for Re-tear in arthroscopic double row rotator cuff repair

A common postoperative complication after rotator cuff repair is re-tear requiring a secondary procedure. Double row and trans-osseous equivalent repair techniques have become increasingly popular in recent years, however repair failure remains a relatively common complication after primary rotator cuff repair. A retrospective observational study of 389 consecutive patients undergoing arthroscopic double-row rotator cuff repair from February 1, 2014 to March 31, 2020 was conducted. Univariate and multivariate statistics were used to assess differences in demographics, comorbidities, and tear characteristics between patients who experienced re-tear and those who did not. Repair failures were confirmed by plain MRI or intraoperatively during repeat surgical treatment. A subgroup analysis of patients who experienced re-tear due to medial row failure was conducted. The overall re-tear rate was 8.2% (32 patients). Six patients (1.5%) experienced medial row failure, while 26 patients (6.7%) experienced lateral row failure. The average time to re-tear was 279.3 ± 291.2 days. On multivariate analysis, patients with Goutallier Classification ≥3 (OR: 4.274, p = 0.046) and 3 anchor repair (OR: 5.387, p = 0.027) were at significantly increased risk for any re-tear after controlling for other tear characteristics. No statistically significant independent risk factors for medial row failure were identified after controlling for confounding variables. Goutallier classification greater than 3 and a primary repair with 3 anchors are significant risk factors for re-tear after double row rotator cuff repair, however they are not associated with increased occurrence of medial row failure. Further evaluation of risk factors for medial row failure is required to avoid this rare but serious re-tear pattern.

Clinical outcomes of arthroscopic single and double row repair in full thickness rotator cuff tears

Background:

There has been a recent interest in the double row repair method for arthroscopic rotator cuff repair following favourable biomechanical results reported by some studies. The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears.

Materials and Methods:

22 patients of arthroscopic single row repair (group I) and 25 patients who underwent double row repair (group II) from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES).

Results:

In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method.

Conclusions:

Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

The effect of intravenous tranexamic acid on visual clarity during arthroscopic rotator cuff repair: A randomized,double-blinded,placebo-controlled pilot study

ObjectiveThe aim of this study was to determine the effect of intravenous (IV) tranexamic acid (TRX) use on visual clarity during arthroscopic rotator cuff repair.MethodsThis prospective, randomized, double-blinded, placebo-controlled study was conducted in patients scheduled for an arthroscopic rotator cuff repair. In total, 60 patients were randomly distributed into two groups: control (28 patients: 11 male, 17 female; mean age=53 years, age range=19–65) and TRX (32 patients: 15 male, 17 female; mean age=50, age range=18–69). In the TRX group, the arthroscopy was performed through the bolus IV administration of 10 mg/kg TRX in 100 ml isotonic saline solution. In the control group, the arthroscopy was performed through the bolus IV administration of 100 ml isotonic saline solution. In both the groups, the IV administration was carried out after the induction of anesthesia. At the end of each procedure, the surgeon rated the visual clarity on a scale from 1 to 10. In addition, operation time (minutes), irrigation amount used in operation (lt), and the need of pressure increase because of bleeding were recorded.ResultsNo adverse effects were seen during the study period. Visual clarity in TRX group was significantly better than the control group (the mean visual clarity scores=8.1/10 (range=7–10) vs 7/10 (range=5–9); p=0.018). The amount of solution was significantly less in the TRX group (10.2 lt (range=3.5–21)) than in the control group (15.8 lt (range=5.8–27); p=0.007, post-hoc power=95.7%), although the operation time was slightly longer in the TRX group (106 minutes (range=50–210)) than in the control group (99 minutes (range=45–165); p=0.24). Moreover, the need for the increase in pressure owing to bleeding was found significantly less in the TRX group (5.8 times (range=(0–9)) than in the control group (9.6 times (range=0–13); p=0.04, post-hoc power=94.5%).ConclusionPreoperative IV TRX administration seems to be effective in improving visual clarity and reducing the need for high pressure and the amount of irrigation fluid during the arthroscopic rotator cuff repair.Level of EvidenceLevel II, Therapeutic study     

Revisiting the rotator cuff footprint

Newer studies challenged the traditionally held belief that the supraspinatus inserts on the entire superior facet and the infraspinatus is attached on the entire middle facet of the greater tuberosity. They showed that the infraspinatus tendon is thicker anteriorly and can be differentiated from the posterior part of the supraspinatus. Hence, the newer studies showed that the supraspinatus attached in a much smaller area than previously thought, and infraspinatus occupied the lateral part of the superior facet of the greater tuberosity. This review aimed to present all the older and current knowledge of the rotator cuff insertion and discuss how this knowledge may affect the surgical repair of the rotator cuff tendons. Our review has synthesized and compared the differences and similarities between the older and the newer knowledge about the footprint anatomy of the cuff tendons and the capsule attachment. We have also highlighted how the newer knowledge impacts the way we treat the tears of the rotator cuff tendons.Level of evidenceReview of basic science studies.     

Re-tears after rotator cuff repair: Current concepts review

Re-tear following rotator cuff repair is common and has been reported to range from between 13 and 94% despite satisfactory clinical outcomes following rotator cuff surgery. Various risk factors have been associated with an increased tear rate, including patient factors, tear and shoulder morphology, repair technique, and rehabilitation regimes. Different modes of rotator cuff failure have been described. The management of re-tear in patients following rotator cuff repair is challenging and depends on the age, functional status and requirements of the patient, and re-tear size and residual tendon length. This article aims to review the factors associated with rotator cuff re-tear. It describes which of these are associated with poor clinical outcomes, and discusses the long-term outcomes of re-tear and treatment options.     

Midterm clinical outcomes following arthroscopic transosseous rotator cuff repair

Purpose:Arthroscopic transosseous (TO) rotator cuff repair has recently emerged as a new option for surgical treatment of symptomatic rotator cuff tears. Limited data is available regarding outcomes using this technique. This study evaluated midterm clinical outcomes following a novel arthroscopic TO (anchorless) rotator cuff repair technique.Results:Statistically significant improvements were noted in forward flexion, external rotation and internal rotation (P < 0.0001). Average postoperative subjective shoulder value was 93.7, simple shoulder test 11.6, and American Shoulder and Elbow Surgeons (ASES) score 94.6. According to ASES scores, results for the 109 shoulders available for final follow-up were excellent in 95 (87.1%), good in 8 (7.3%), fair in 3 (2.8%), and poor in 3 (2.8%). There was no difference in ROM or outcome scores in patients who underwent a concomitant biceps procedure (tenodesis or tenotomy) compared with those who did not. Furthermore, there was no significant difference in outcome between patients who underwent either biceps tenodesis or tenotomy. Age, history of injury preceding the onset of pain, tear size, number of TO tunnels required to perform the repair, and presence of fatty infiltration did not correlate with postoperative ROM or subjective outcome measures at final follow-up. Two complications and four failures were noted.Conclusions:Arthroscopic TO rotator cuff repair technique leads to statistically significant midterm improvement in ROM and satisfactory midterm subjective outcome scores with low complication/failure rates in patients with average medium-sized rotator cuff tears with minimal fatty infiltration. Further work is required to evaluate radiographic healing rates with this technique and to compare outcomes following suture anchor repair.

Open versus arthroscopic treatment of chronic rotator cuff impingement

We report the results of 238 consecutive patients who underwent in total 261 acromioplasties because of chronic rotator cuff impingement. The procedure was performed either in conventional open technique (80) or arthroscopically (181). Two years (1–10) after the operation 68% of the patients treated with the open technique had an excellent or good result compared 82% of the patients treated arthroscopically by an experienced arthroscopic surgeon. Compared to the open technique, the arthroscopic procedure had a statistically significant superior result concerning outcome, operating time and hospital stay. Arthroscopic procedures performed by less experienced surgeons had inferior results. Received: 3 July 2000
