Do elderly patients gain as much benefit from arthroscopic rotator cuff repair as their younger peers?

Factors associated with patient satisfaction after arthroscopic rotator cuff repair: do they differ by age?

BACKGROUND

Several studies have investigated factors affecting patient satisfaction after arthroscopic rotator cuff repair (ARCR); however, it is unknown if these factors vary according to age. Therefore, this study aimed to evaluate the factors associated with satisfaction of ARCR in individuals 70 years and older versus younger patients.

METHODS

Among 319 consecutive patients who underwent ARCR, 173 were included. Patients were divided into an old age group (≥70 years) and a young age group (<70 years), and the two age groups were further divided into satisfied and unsatisfied subgroups. Patient satisfaction was evaluated at the final follow-up visit using a binary question (yes or no). Clinical outcomes were assessed preoperatively and at the final follow-up.

RESULTS

Satisfaction rates in the older and younger age groups were 75.41% and 79.47%, respectively. Mean changes in Constant and American Shoulder and Elbow Surgeons scores were significantly different between the satisfied and unsatisfied subgroups (P=0.031 and P=0.012, respectively) in the young patients. In the old patients, there was a significant difference in the mean change in depression subscale of the Hospital Anxiety and Depression Scale (P=0.031) and anxiety subscale of the Hospital Anxiety and Depression Scale (P=0.044) scores between the satisfied and unsatisfied subgroups.

CONCLUSIONS

Factors affecting patient satisfaction after ARCR differed according to age. Psychological improvement was more important to elderly patients, whereas restoration of function was more important to younger patients. Pain relief was important for both age groups. Level of evidence: III.

Hawkins award 2023: clinical outcome and tendon healing after arthroscopic repair of isolated supraspinatus tears: a retrospective comparative study in patients older than 70 years vs. patients younger than 50 years

Background

The purpose of this study was to evaluate and compare the clinical and structural outcomes after arthroscopic repair of isolated supraspinatus tears in patients older than 70 years vs. patients younger than 50 years to determine whether age influences the treatment of these tears.

Methods

We conducted a retrospective, comparative study of 87 shoulders of 86 patients older than 70 years who underwent rotator cuff repair after isolated full-thickness supraspinatus tear between January 2010 and December 2020. A control group of 87 patients younger than 50 years was matched for sex, body mass index, smoking habits, tendon retraction according to Patte and fatty infiltration according to Goutallier. Clinical assessment used Constant-Murley Score (CMS), age- and sex-matched Constant Scores and Subjective Shoulder Value at 6 months. Cuff integrity was evaluated using ultrasonography based on the Sugaya criteria, types I-II-III being considered as healed.

Results

The CMS significantly improved by +17.91 points in elderly patients compared with +7.47 points in controls (P < .1) and activity (P = .2), mobility (P < .1), and strength (P < .1). The adjusted CMS significantly improved by +24.94 in elderly patients compared with +8.49 points in controls (P < .1). The Subjective Shoulder Value improved by +29.48 points in elderly patients compared with +23.47 points in controls. The improvement was similar in both groups. (P < .10). Satisfaction was similar in both groups (P = .31). Regarding structural outcomes, patients younger than 50 years presented better results in terms of healing than patients older than 70 years, as the healing rate was 73.7% in the elderly group and 88.5% in the control group (P = .1). The clinical outcomes were not significantly associated with the tendon healing (P = .1).

Conclusion

Functional gain for patients older than 70 years is better than their younger peers despite their low-grade healing. Arthroscopic repair after isolated supraspinatus tears should be considered as a valuable treatment regardless the age.

Clinical and Structural Outcomes of Arthroscopic Rotator Cuff Repair in Patients Over 75 Years Are Comparable to Those in Younger Patients: A Propensity Score-Matched Comparative Study

PURPOSE

To compare clinical and structural outcomes of arthroscopic rotator cuff repair (ARCR) in patients over 75 years and those under 75 years and to analyze the factors associated with retear and clinical outcomes after ARCR.

METHODS

This retrospective study reviewed patients who underwent ARCR between 2011 and 2021 with at least 2 years of follow-up. Using propensity score matching for sex, tear size, subscapularis involvement, and follow-up time, this study included 54 patients older than 75 years (group A) and 54 patients younger than 75 years (group B). Cuff integrity was evaluated using magnetic resonance imaging (MRI). Structural and clinical outcomes were compared between the 2 groups.

RESULTS

The mean improvements in external rotation (P = .030) and the American Shoulder and Elbow Surgeons (ASES) score (P = .043) were significantly higher in group A. Visual analog scales for pain and function, ASES score, and Constant score were significantly improved in both groups (all P = .001). On routine postoperative MRI at 6 months, the retear rate was 20.4% (11/54) in group A and 18.5% (10/54) in group B with no statistical difference between the 2 groups (P = .808). Factor analysis in group A showed that follow-up duration (P = .019), tear size in mediolateral dimension (P = .037), occupation ratio (P = .036), and incomplete repair (P = .034) were associated with retear, and mild glenohumeral arthritis (P = .003) and subscapularis involvement (P = .018) were associated with inferior Constant score.

CONCLUSIONS

Clinical and structural outcomes after ARCR in patients aged 75 years or older are comparable to those in patients younger than 75 years.

Online Videos Regarding Relevant Postoperative Patient Information and Postoperative Rehabilitation After Arthroscopic Rotator Cuff Repair Provide Poor Information Quality, Accuracy, and Reliability

PURPOSE

To evaluate the information quality, accuracy, and reliability of YouTube videos regarding relevant postoperative patient information and postoperative rehabilitation after arthroscopic rotator cuff repair.

METHODS

By use of The Onion Router (TOR) software and predefined search terms, 102 videos were assessed. Four scoring systems were used to evaluate included videos: (1) Journal of the American Medical Association (JAMA) benchmark criteria score; (2) Global Quality Score (GQS); (3) DISCERN score; and (4) a newly developed score, the Rotator Cuff Score (RCS). The RCS (0-30 points) was built based on the latest published evidence and guidelines from the American Academy of Orthopaedic Surgeons. Videos that scored up to 9 points were regarded as poor-quality videos.

RESULTS

Most of the included videos provided poor information quality, accuracy, and reliability. Videos that were uploaded by medically trained professionals showed significantly better results for all scores compared with commercial or personal-testimony videos (JAMA benchmark criteria score, P < .001; GQS, P < .001; DISCERN score, P = .001; and RCS, P = .001). Multivariate linear regression showed that the involvement of medically trained professionals was a significant predictor of better results for all scores (JAMA benchmark criteria score, β = 1.496 [P < .001]; GQS, β = 1.105 [P < .001]; DISCERN score, β = 11.234 [P < .001]; and RCS, β = 5.017 [P < .001]). Surprisingly, the like ratio was significantly higher for videos that were uploaded by non-medically trained individuals (P = .041).

CONCLUSIONS

The average information quality, accuracy, and reliability of YouTube videos regarding relevant postoperative patient information and postoperative rehabilitation after arthroscopic rotator cuff repair are poor. Videos from medically trained professionals provide significantly higher information quality; however, even these videos lack important information for a better understanding of arthroscopic rotator cuff repair.

CLINICAL RELEVANCE

Because of the lack of a peer-review process, available videos on YouTube regarding relevant postoperative patient information and postoperative rehabilitation after arthroscopic rotator cuff repair are of low quality, accuracy, and reliability. However, patients increasingly visit YouTube to gather medical knowledge. Physicians should enlighten patients about these findings and should be able to provide alternative sources of high-quality information.

Comparison of Outcomes after Arthroscopic Rotator Cuff Repair between Elderly and Younger Patient Groups: A Systematic Review and Meta-Analysis of Comparative Studies

This study aimed to compare the outcomes of arthroscopic rotator cuff repair (ARCR) surgery between younger and older patients. We performed this systematic review and meta-analysis of cohort studies comparing outcomes between patients older than 65 to 70 years and a younger group following arthroscopic rotator cuff repair surgery. We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and other sources for relevant studies up to 13 September 2022, and then assessed the quality of included studies using the Newcastle-Ottawa Scale (NOS). We used random-effects meta-analysis for data synthesis. The primary outcomes were pain and shoulder functions, while secondary outcomes included re-tear rate, shoulder range of motion (ROM), abduction muscle power, quality of life, and complications. Five non-randomized controlled trials, with 671 participants (197 older and 474 younger patients), were included. The quality of the studies was all fairly good, with NOS scores ≥ 7. The results showed no significant differences between the older and younger groups in terms of Constant score improvement, re-tear rate, or other outcomes such as pain level improvement, muscle power, and shoulder ROM. These findings suggest that ARCR surgery in older patients can achieve a non-inferior healing rate and shoulder function compared to younger patients.

"Functional outcomes and MRI-based tendon healing after (antero-) superior rotator cuff repair among patients under 50 years: retrospective analysis of traumatic versus non-traumatic rotator cuff tears"

BACKGROUND

Rotator cuff tears among patients under 50 years either result from an adequate trauma or are considered non-traumatic due to work-related or athletic overuse. The impact of these different mechanisms on postoperative functional outcomes and tendon healing has not yet been fully understood. Therefore, it was the purpose of this study to investigate the influence of etiology of (antero-)superior rotator cuff tears on postoperative outcomes and the healing rates after arthroscopic rotator cuff repair in a young patient population.

METHODS

Patients under 50 years who underwent arthroscopic rotator cuff repair between 2006-2017 for an anterosuperior rotator cuff tear with a minimum follow up of 24 months were included in this study. Revision surgeries or reconstructive concomitant procedures other than long head of the biceps tenodesis were excluded. Patients were divided into two groups according to the etiology of their rotator cuff tear (traumatic vs. non-traumatic). Demographic and outcome scores including the American Shoulder and Elbow Surgeons (ASES) score, the Constant Score (CS), bilateral strength measurements and postoperative tendon integrity evaluated on magnetic resonance imaging (MRI) were assessed and compared between both groups.

RESULTS

The mean follow up for this study was 55.6 months (24 - 158). Twenty-one patients (50.0%) had a traumatic RCT and 21 patients (50.0%) had a non-traumatic tear. Outcome scores did not differ significantly between groups. Strength measurements of the supraspinatus revealed significantly decreased force of the affected side as opposed to the contralateral side (p = 0.001), regardless of etiology. Retear rates were similar in both groups (37.5% and 33.3%, p = n.s.). Cuff integrity at follow-up was not predictive of superior scores or strength.

CONCLUSION

Surgical treatment of traumatic and non-traumatic RCT yields good clinical results in patients under the age of 50. The etiology of the rotator cuff tear did not significantly affect postoperative outcomes or healing rates. About one third of the patients suffered from a retear postoperatively, however retears were not predictive of inferior outcomes at midterm follow-up.

Repair of rotator cuff tears in patients aged 75 years and older: Does it make sense? A systematic review

Background

Rotator cuff injuries are common, and morbidity increases with age. The asymptomatic full-thickness tear rate is 40% in the over 75-year-old population.

Purpose

This study aimed to systematically review the literature on the outcomes of rotator cuff repair among >75 years old patients.

Study design

Systematic review.

Methods

A systematic review of the literature was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search was performed in the electronic databases of PubMed, Medline, Embase, and The Cochrane Library. Studies in English evaluating repair of full-thickness rotator cuff tears in patients aged >75 years were included.

Results

Six studies were reviewed, including 311 patients (313 shoulders) treated with arthroscopic and/or open rotator cuff repair. Sixty-one patients were lost to follow-up, leaving 252 shoulders with outcome data. Patients in this age group demonstrated a significant improvement in the clinical and functional scores after rotator cuff repair, with a high satisfaction rate. The mean American Shoulder and Elbow Surgeons scores improved from 43.8 (range, 42.0-45.5) preoperatively to 85.3 (range, 84.0 to 86.5) postoperatively, and the mean Constant scores improved from 45.4 (range, 34.7-55.5) to 78.6 (range, 67.0-91.6). Pain, evaluated in all studies by the visual analog scale for pain, showed a significant improvement at the last follow-up compared with the mean preoperative score. Furthermore, range of motion and return to daily activities and sports gained marked improvements.

Conclusion

Rotator cuff repair in patients aged >75 years could achieve high clinical success rates with good outcomes and pain relief. Although patients in this age group are at a high risk of retear, rotator cuff repair may offer a good option with significant functional and clinical improvement.

Long-term Results of Arthroscopic Repair of Full-Thickness Traumatic Rotator Cuff Tears in Active Duty Military Patients Under the Age of 40 Years

BACKGROUND

Arthroscopic rotator cuff repair is an effective procedure through which to decrease pain and increase strength, with favorable long-term outcomes demonstrated in older patient populations with full-thickness rotator cuff tears. The long-term outcomes after this procedure in younger, higher-demand patients, however, is not as clearly defined.

PURPOSE

To report on the long-term outcomes after arthroscopic rotator cuff repair of traumatic full-thickness rotator cuff tears in active duty military patients under the age of 40 years at the time of surgery.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Preoperative, midterm, and final evaluations were collected, including scores on the visual analog scale for pain, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons shoulder form. A total of 42 patients were screened for inclusion: 3 underwent additional surgical procedures on the operative shoulder and 2 were lost to follow-up, leaving 37 patients with mean follow-up of 104.51 months available for analysis. A subgroup analysis was performed comparing outcomes between patients with Southern California Orthopaedic Institute grade 1 or 2 tears and those with grade 3 or 4 tears.

RESULTS

At final follow-up, pain per the visual analog scale decreased to 1.16 from 8.03 (P < .0001); the Single Assessment Numeric Evaluation score increased to 87.32 from 48.24 (P < .0001); and the American Shoulder and Elbow Surgeons score increased to 88.68 from 41.00 (P < .0001). There was no statistically significant difference in outcome scores or range of motion between midterm and final follow-up. Improvement in outcome scores and range of motion at final follow-up did not vary between patients with small and large tears. Of 42 patients, 37 (88.1%) were able to return to full unrestricted active duty and sporting activity, while 5 (11.9%) were medically separated from the military.

CONCLUSION

Active duty military patients under the age of 40 years with traumatic full-thickness rotator cuff tears had statistically and clinically significant increases in outcome scores and decreases in pain after arthroscopic rotator cuff repair at long-term follow-up.

Comparing Sex-Specific Outcomes After Rotator Cuff Repair: A Meta-analysis

Background

Rotator cuff repair (RCR) is a well-studied procedure. However, the impact of patient sex on outcomes after RCR has not been well studied.

Purpose

To conduct a systematic review and meta-analysis of sex-based differences in outcomes after RCR and to record what proportion of studies examined this as a primary or secondary purpose.

Study Design

Systematic review; Level of evidence, 4.

Methods

A systematic review was performed using multiple databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies were included if they were written in English, performed on humans, consisted of patients who underwent RCR, evaluated at least 1 of the selected outcomes based on patient sex, and had statistical analysis available for their sex-based claim. Excluded were case reports, review studies, systematic reviews, cadaveric studies, and studies that did not report at least 1 sex-specific outcome or included certain other injuries associated with a rotator cuff injury.

Results

Of 9998 studies screened and 1283 full-text studies reviewed, 11 (0.11%) studies with 2860 patients (1549 male and 1329 female) were included for quantitative analysis. None of these 11 studies examined the impact of patient sex on outcomes after RCR as a primary outcome. Postoperative Constant-Murley scores were analyzed for 7 studies. Male patients had a postoperative Constant-Murley score of 76.77 ± 15.94, while female patients had a postoperative Constant-Murley score of 69.88 ± 17.02. The random-effects model showed that male patients had significantly higher scores than female patients, with a mean difference of 7.33 (95% CI, 5.21-9.46; P < .0001). Analysis of retear rates in 5 studies indicated that there was no difference in the retear rate between sexes (odds ratio, 0.91 [95% CI, 0.49-1.67]).

Conclusion

Female patients had lower postoperative Constant-Murley scores compared with male patients, but there was no difference in the retear rate. However, these results were based on an analysis of only 11 studies. The paucity of studies examining the impact of sex suggests that more research is needed on the impact of patient sex on outcomes after RCR.

Are there differences in arthroscopic and histological features between traumatic and degenerative rotator cuff tears in elderly patients? A prospective dual-center analysis

Background

Discriminating traumatic rotator cuff tears (RCTs) from degenerative RCTs is sometimes difficult in elderly patients because the prevalence of asymptomatic RCTs increases with age. Little intraoperative information is available on the characteristics of traumatic and degenerative RCTs in elderly patients. The purpose of this study was to compare the arthroscopic findings and histological changes of the coracoacromial ligament (CAL) between traumatic and degenerative RCTs in elderly patients.

Methods

Forty-two shoulders of 42 patients aged ≥ 65 years underwent arthroscopic rotator cuff repair. Nineteen patients had traumatic full-thickness RCTs (Group T), and 23 had degenerative full-thickness RCTs (Group D). The quality of the rotator cuff tissue and the condition of the long head of the biceps were examined. The grade of CAL was evaluated both arthroscopically and histologically. The stiffness of the musculotendinous unit was calculated by measuring the force and displacement using a tensiometer. The arthroscopic and histological findings of the two groups were compared.

Results

Although the mean tendon displacement was comparable, the stiffness was different between Group T and Group D (0.56 ± 0.31 and 1.09 ± 0.67 N/mm, respectively; p < 0.001). Both arthroscopic and histological analysis of the CAL showed that the degenerative changes in the CAL were milder in Group T than in Group D (p < 0.001 and p < 0.001, respectively). There was a moderate positive correlation between the arthroscopic findings of CAL degeneration and the histopathological changes in this ligament (r = 0.47, p = 0.002).

Conclusions

Traumatic RCTs were characterized by preserved elasticity of the musculotendinous unit and milder CAL degeneration compared with degenerative RCTs even in elderly patients.

Comparing the Predictors of Functional Outcomes After Arthroscopic Rotator Cuff Repair Modified Frailty Index, Clinical Frailty Scale, and Charlson Comorbidity Index

Background:

The incidence of rotator cuff tears increases with age, and operative management is usually required in patients with persistent symptoms. Although several studies have analyzed the effect of age and comorbidities on outcomes after rotator cuff repair, no study has specifically examined the consequence of frailty.

Purpose:

To determine the best frailty/comorbidity index for predicting functional outcomes after arthroscopic rotator cuff repair.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

The authors conducted a retrospective cohort study of 340 consecutive patients who underwent unilateral arthroscopic rotator cuff repair at a tertiary hospital between April 2016 and April 2018. All patients had undergone arthroscopic double-row rotator cuff repair with subacromial decompression by a single fellowship-trained shoulder surgeon. Patient frailty was measured using the Modified Frailty Index (MFI), Clinical Frailty Scale (CFS), and Charlson Comorbidity Index (CCI), calculated through retrospective chart review based on case notes made just before surgery; patient age and sex were also noted preoperatively. Functional outcomes using the Oxford Shoulder Score (OSS), Constant Shoulder Score (CSS), University of California Los Angeles (UCLA) Shoulder Score, and visual analog scale for pain were measured preoperatively and at 3, 6, 12, and 24 months postoperatively.

Results:

The MFI was a consistent significant predictor in all functional outcome scores up to 24 months postoperatively (P < .05), unlike the CFS and CCI. Sex was also a significant predictor of postoperative OSS, CSS, and UCLA Shoulder Score, with male sex being associated with better functional outcomes. Patients with higher MFI scores had slower functional improvement postoperatively, but they eventually attained functional outcome scores comparable with those of their counterparts with lower MFI scores at 24 months postoperatively.

Conclusion:

The MFI was found to be a better tool for predicting postoperative function than was the CFS or CCI in patients undergoing arthroscopic rotator cuff repair. The study findings suggest that a multidimensional assessment of frailty (including both functional status and comorbidities) is important in determining functional outcomes after arthroscopic rotator cuff repair.

Clinical midterm results of arthroscopic rotator cuff repair in patients older than 75 years

BACKGROUND

The effect of patient age on functional improvement after arthroscopic rotator cuff repair (ARCR) is still a matter of debate. The purpose of this study was to evaluate the clinical midterm results after ARCR in patients who were 75 years or older at the time of surgery.

METHODS

A total of 31 shoulders in 30 patients older than 75 years at the time of surgery underwent ARCR for a degenerative full-thickness rotator cuff tear (RCT) between 2010 and 2016. Among those, 23 shoulders in 22 patients (74%) with a mean age at time of surgery of 77 ± 2 years (range, 75-82 years) were followed up after a mean of 7 ± 2 years (range, 3-9 years). Clinical assessment included the Western Ontario Rotator Cuff (WORC) index as well as patient satisfaction, the Subjective Shoulder Value (SSV), Simple Shoulder Test (SST), and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score.

RESULTS

Overall, patient satisfaction was excellent, as everybody stated to be very satisfied with the surgery. Neither any complication nor revision surgery occurred during the study period. At final follow-up, the mean WORC index was 88% ± 15%. The mean SSV was comparable between the affected shoulder (90% ± 15%) and the contralateral side (87% ± 15%) (P = .235). The mean SST score was 10 ± 2 points and the mean ASES score was 89 ± 17 points.

CONCLUSION

ARCR for symptomatic RCTs without advanced muscle degeneration in patients older than 75 years at the time of surgery provided good clinical results and high patient satisfaction at midterm follow-up.

Midterm outcomes of arthroscopic rotator cuff repair in patients aged 75 years and older

BACKGROUND

Full-thickness rotator cuff tears remain a significant cause of pain and dysfunction in the elderly. Substantial improvement in pain and functional outcomes with arthroscopic cuff repair is possible. Recent data has shown that patients older than 70-75 years still have clinical improvement with operative rotator cuff repair.

MATERIALS AND METHODS

This is a retrospective study of patients aged ≥75 years undergoing arthroscopic rotator cuff repair at a minimum of 24 months after surgery. Outcome measurements included range of motion (ROM), visual analog scale (VAS) pain scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, Single Assessment Numeric Evaluation (SANE) scores, and Short Form Health Survey (SF-12) scores. Reoperation and rates of conversion to reverse shoulder arthroplasty (RSA) were determined.

RESULTS

Eighty-three patients were included with an average follow-up of 56.9 ± 25.9 months (range 24-127 months). Six (7.2%) patients had additional surgery, including 3 revision rotator cuff repairs for retear, 2 conversion to RSA, and 1 capsular release and loose anchor removal. There were statistically significant improvements in shoulder ROM, ASES, SANE, VAS, and SF-12 scores postoperatively.

CONCLUSION

Rotator cuff repair in select patients aged ≥75 years results in reliable improvements in pain and function. There was a low reoperation rate or conversion to RSA (7.2%) at midterm follow-up. This study indicates a role for rotator cuff repair in an elderly population and argues against the routine use of reverse arthroplasty for repairable rotator cuff tears in this population.
