Effect of preoperative patient expectations on outcomes after reverse total shoulder arthroplasty

Preoperative Risk Factors for Pain After Reverse Total Shoulder Arthroplasty: A Systematic Review

Despite being a generally successful procedure, pain following reverse total shoulder arthroplasty (rTSA) is a known complication. The aim of this systematic review is to identify preoperative risk factors for pain following rTSA to encourage evidence-based interventions, inform clinicians, and aid in surgical planning. Studies that reported preoperative risk factors and pain after rTSA were included. Studies which reported outcome measures that incorporated pain scores yet did not display them independently, studies which only reported intraoperative risk factors, and studies involving participants under 18 were excluded. The search was conducted on May 31, 2023, across the following databases: PubMed, Web of Science, Embase, Scopus, and Cochrane Central Register of Controlled Trials. Four independent researchers conducted this systematic review, and a descriptive analysis was subsequently performed. Twenty-five studies were included following the evaluation of full-text articles, involving a total of 9,470 shoulders. Preoperative risk factors identified were categorised into the following groups: BMI, smoking, radiographic findings, age and sex, prior surgery, functional ability and pain, and psychosocial. The strongest associations identified were preoperative opioid use and smoking, which were both associated with worse pain outcomes following rTSA; other preoperative risk factors highlighted in this review showed either weak or no correlation. Preoperative opioid use and smoking are likely risk factors for the development of pain after rTSA. Although the studies included varying levels of quality, the identification of modifiable risk factors is useful in optimising management prior to surgery and guiding patient expectations. The lack of evidence regarding associations with non-modifiable risk factors further reinforces the potential benefits of the procedure on diverse population groups and is useful in itself for assessing the candidacy of patients for the procedure, particularly when postoperative pain is a factor being considered.

Evaluation of Patient Expectations and Outcomes after Distal Radius Fractures

BACKGROUND

Patient expectations influence patient-reported outcomes after musculoskeletal injuries. The goal of this study is to determine how pretreatment expectations correlate with outcomes in patients with distal radius fractures.

METHODS

Seventy-five patients with an isolated distal radius fracture were prospectively enrolled into nonoperative and operative cohorts. The Trauma Expectation Factor-Trauma Outcome Measure (TEF-TOM) score was the primary outcome measure. Trauma Expectation Factor scores were recorded at the time of enrollment, and TOM scores were recorded at 3, 6, and 12 months. Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) and Patient-Rated Wrist Evaluation (PRWE) scores were also recorded.

RESULTS

Trauma Outcome Measure scores at all time points were worse than expected (P < .01). Expectations were higher for patients younger than 65 years than for the 65+ group (P = .02). In patients aged 65+ years, mean TOM at 3 months was not significantly different than expected (P = .11) but decreased by 6 (P = .04) and 12 months (P < .01). Baseline TEF and TEF-TOM scores were not significantly different between operative and nonoperative groups (P = .37). Quick Disabilities of the Arm, Shoulder, and Hand and PRWE scores were not significantly different between age or treatment groups at the final follow-up.

CONCLUSIONS

The overall treatment of distal radial injuries in our study did not meet patient expectations. Patients aged 65 years or older had lower expectations but were not able to predict their outcomes better than patients aged <65 years. There were no differences in TEF or TOM by treatment method. Patients demonstrated improved functional outcomes (qDASH/PRWE) at all time points regardless of age and treatment method.

Postoperative results of arthroscopic superior capsule reconstruction using fascia lata: a retrospective cohort study

BACKGROUND

Superior capsule reconstruction (SCR) was developed to improve shoulder function and alleviate pain in patients with primary irreparable rotator cuff tears. Although suitable clinical results of SCR have been reported, only a few studies have investigated the clinical outcomes of arthroscopic superior capsule reconstruction (ASCR) using tensor fascia at a minimum follow-up period of 2 years after surgery.

METHODS

Among 100 consecutive patients who underwent ASCR since April 2010, this retrospective cohort study included 49 patients with a Hamada classification of ≤3 who were available for at least 2-year follow-up after surgery. The mean follow-up period was 34.5 (24-74) months. We analyzed preoperative and postoperative Japanese Orthopaedic Association (JOA) scores, University of California at Los Angeles (UCLA) shoulder scores, preoperative and postoperative active elevation angles, external and internal rotations with the arms in the anatomical position, manual muscle test (MMT) scores, preoperative and postoperative acromiohumeral distance (AHD), and cuff integrity on postoperative magnetic resonance imaging using the Hasegawa classification. We compared 27 pseudoparalyzed (elevation of <90°) shoulders with 22 nonpseudoparalyzed shoulders. We also evaluated the treatment of patients with subscapularis tendon tears and compared the outcomes of patients with good graft repair and those with graft retear.

RESULTS

The JOA score, UCLA score, active elevation angle, internal and external rotation angles, and muscle strength (MMT) significantly improved at the time of investigation preoperatively and 2 years postoperatively. The mean AHD also improved from 5 ± 2.6 mm preoperatively to 9 ± 2.8 mm postoperatively. No significant difference in graft tear rate was observed between pseudoparalyzed shoulder and nonpseudoparalyzed shoulder groups. The subscapularis tendon was torn in 26 of 49 (53%) patients, and all patients underwent repair. The graft repair group showed a significant improvement in JOA scores, UCLA shoulder scores, joint range of motion, MMT, and AHD postoperatively, but not in internal rotation strength. In contrast, the graft tear group did not show any significant improvement. All patients could return to work, except for those performing heavy labor. Complications included graft tear in five patients, postoperative infection in two patients, and progressive postoperative arthropathic changes in one patient.

CONCLUSION

Good clinical results of ASCR were obtained using tensor fascia lata at 2 years after surgery, with few complications and low graft tear rates.

Primary reverse total shoulder arthroplasty for fractures requires more revisions than for degenerative conditions 1 year after surgery: an analysis from the Dutch Arthroplasty Register

BACKGROUND

Although reverse total shoulder arthroplasty (RTSA) is considered a viable treatment strategy for proximal humeral fractures, there is an ongoing discussion of how its revision rate compares with indications performed in the elective setting. First, this study evaluated whether RTSA for fractures conveyed a higher revision rate than RTSA for degenerative conditions (osteoarthritis, rotator cuff arthropathy, rotator cuff tear, or rheumatoid arthritis). Second, this study assessed whether there was a difference in patient-reported outcomes between these 2 groups following primary replacement. Finally, the results of conventional stem designs were compared with those of fracture-specific designs within the fracture group.

MATERIALS AND METHODS

This was a retrospective comparative cohort study with registry data from the Netherlands, generated prospectively between 2014 and 2020. Patients (aged ≥ 18 years) were included if they underwent primary RTSA for a fracture (<4 weeks after trauma), osteoarthritis, rotator cuff arthropathy, rotator cuff tear, or rheumatoid arthritis, with follow-up until first revision, death, or the end of the study period. The primary outcome was the revision rate. The secondary outcomes were the Oxford Shoulder Score, EuroQol 5 Dimensions (EQ-5D) score, numerical rating scale score (pain at rest and during activity), recommendation score, and scores assessing change in daily functioning and change in pain.

RESULTS

This study included 8753 patients in the degenerative condition group (mean age, 74.3 ± 7.2 years) and 2104 patients in the fracture group (mean age, 74.3 ± 7.8 years). RTSA performed for fractures showed an early steep decline in survivorship: Adjusted for time, age, sex, and arthroplasty brand, the revision risk after 1 year was significantly higher in these patients than in those with degenerative conditions (hazard ratio [HR], 2.50; 95% confidence interval, 1.66-3.77). Over time, the HR steadily decreased, with an HR of 0.98 at year 6. Apart from the recommendation score (which was slightly better within the fracture group), there were no clinically relevant differences in the patient-reported outcome measures after 12 months. Patients who received conventional stems (n = 1137) did not have a higher likelihood of undergoing a revision procedure than those who received fracture-specific stems (n = 675) (HR, 1.70; 95% confidence interval, 0.91-3.17).

CONCLUSION

Patients undergoing primary RTSA for fractures have a substantially higher likelihood of undergoing revision within the first year following the procedure than patients with degenerative conditions preoperatively. Although RTSA is regarded as a reliable and safe treatment option for fractures, surgeons should inform patients accordingly and incorporate this information in decision making when opting for head replacement surgery. There were no differences in patient-reported outcomes between the 2 groups and no differences in revision rates between conventional and fracture-specific stem designs.

Patient Expectations and Satisfaction in Pediatric Orthopedics

PURPOSE OF REVIEW

The purpose of the current review is to analyze the current literature regarding the tools available to evaluate patient expectations and satisfaction. There have been an increasing number of tools that have been developed and validated for various orthopedic procedures. Despite the growing number of tools, there are a limited number of tools available for pediatric patients.

RECENT FINDINGS

Several tools have been developed in orthopedics to evaluate patient expectations. However, there are no tools that have been validated in the pediatric population. In addition, pediatric patient expectations should be collected in conjunction with parent/caregiver expectations. Although not specifically validated for pediatric patients, there are several tools available that may pertain to pediatric patients including the HSS ACL Expectations Survey, HSS Shoulder Expectations Survey, HSS Knee Surgery Expectations Survey, HSS Foot and Ankle Surgery Expectation Survey, Sunnybrook Surgery Expectations Survey, Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) Instruments, Quick DASH, and DASH. In terms of patient satisfaction, there are even fewer tools available. Several tools have been developed to evaluate patient satisfaction and five additional tools within orthopedics. Of these tools, there are two that have been validated for pediatric patients: The Swedish Parents Satisfaction Questionnaire and the Scoliosis Research Society-22. There are a growing number of tools to evaluate patient's expectations and satisfaction in the orthopedic literature. Given most of these tools pertain to adult patients, there is a need for further development of tools specifically validated for pediatric patients and their parents/caregivers. Through the measurement of expectations and satisfaction, medical professionals can hope to improve satisfaction and outcomes.

Does Reverse Shoulder Arthroplasty Improve Function and Quality of Life in Patients With Rotator Cuff Tear Arthropathy?

Background This study aims to determine the change in functional capacity and quality of life in patients who underwent reverse shoulder arthroplasty (RSA) due to rotator cuff tear arthropathy (RCTA). Methodology A total of 89 patients who underwent RSA due to RCTA between 2016 and 2022 were included in the study, as examined by the senior author. The Constant-Murley Score (CMS) was used for functional assessment, whereas the Short Form-36 (SF-36) was used for quality-of-life evaluation. The assessment scores before and after the surgery were compared to the reference values of CMS and SF-36 scores, as determined by reference studies, based on age groups. The change in functional capacity and quality of life with RSA was calculated. In addition, the impact of age and body mass index (BMI) on the results was examined. Results No differences were found in demographic data except for BMI (p = 0.026). CMS did not reach the reference values of a normal shoulder during the 12-month postoperative period. However, a significant increase of 156% in comparison to the preoperative values was detected (p < 0.001). In the postoperative period, there was a statistically significant improvement in SF-36 scores compared to preoperative scores, except for social functioning (p = 0.099) and vitality (p = 0.255) (for all other parameters, p < 0.001). In patients under the age of 65 years, all parameters except for physical functioning, physical role, and social functioning statistically reached the reference values. A decrease in CMS scores was noted with an increase in BMI, and the negative correlation further increased in the postoperative period (preoperative: r = -0.274, 12-month postoperative: r = -0.476). Conclusions RSA performed for RCTA leads to an improvement in functional outcomes and quality of life. Although there was a considerable improvement after surgery for CMS compared to preoperatively, it was observed that normal shoulder reference values ​​could not be reached. For SF-36, it was observed that it reached normal shoulder reference values, especially in patients over 65 years of age.

Patient definitions of transplant success in upper extremity vascularized composite allotransplantation: A mixed-methods study

Objective

Upper extremity vascularized composite allotransplantation is an innovative treatment option for people with upper extremity amputations. Limited patient-relevant long-term outcomes data about transplant success may impede patients' informed treatment decision-making. We assessed perceptions of what constitutes upper extremity vascularized composite allotransplantation success among individuals with upper extremity amputations.

Methods

This multisite study entailed interviews and focus groups with individuals with upper extremity amputations and upper extremity vascularized composite allotransplantation candidates, participants, and recipients. We examined perceptions of transplant success and preferences for five upper extremity vascularized composite allotransplantation outcomes. Qualitative data were analyzed using thematic analysis; and quantitative data were analyzed using descriptive statistics.

Results

In all, 50 individuals participated in interviews (61.7% participation rate), and 37 participated in nine focus groups (75.5% participation rate). Most were White (72%, 73%), had a mean age of 45 and 48 years, and had a unilateral amputation (84%, 59%), respectively. Participants conceptualized upper extremity vascularized composite allotransplantation success as transplant outcomes: (1) restoring function and sensation to enable new activities; (2) accepting the transplanted limb into one's identity and appearance; (3) not having transplant rejection; (4) attaining greater quality of life compared to prosthetics; and (5) ensuring benefits outweigh risks. Participants rated their most important upper extremity vascularized composite allotransplantation outcomes as follows: not having transplant rejection, not developing health complications, grasping objects, feeling touch and temperature, and accepting the upper extremity vascularized composite allotransplantation into your identity.

Conclusion

Individuals with upper extremity amputations maintain several conceptions of vascularized composite allotransplantation success, spanning functional, psychosocial, clinical, and quality of life outcomes. Providers should address patients' conceptions of success to improve informed consent discussions and outcomes reporting for upper extremity vascularized composite allotransplantation.

The impact of comorbidities on postoperative outcomes of ventral hernia repair: the patients' perspective

INTRODUCTION

Ventral hernia repair (VHR) outcomes can be adversely affected by modifiable patient co-morbidities, such as diabetes, obesity, and smoking. Although this concept is well accepted among surgeons, the extent to which patients understand the significance of their co-morbidities is unknown, and a few studies have sought to determine patient perspectives regarding the impact of their modifiable co-morbidities on their post-operative outcomes. We attempted to determine how accurately patients predict their surgical outcomes after VHR compared to a surgical risk calculator while considering their modifiable co-morbidities.

METHODS

This is a prospective, single-center, survey-based study evaluating patients' perceptions of how their modifiable risk factors affect outcomes after elective ventral hernia repair. Pre-operatively, after surgeon counseling, patients predicted the percentage of impact that they believed their modifiable co-morbidities (diabetes, obesity, and smoking) had on 30-day surgical site infections (SSI) and hospital readmissions. Their predictions were compared to the Outcomes Reporting App for CLinicians and Patient Engagement (ORACLE) surgical risk calculator. Results were analyzed using demographic information.

RESULTS

222 surveys were administered and 157 were included in the analysis after excluding for incomplete data. 21% had diabetes, 85% were either overweight with body mass index (BMI) 25-29.9 or obese (BMI ≥ 30), and 22% were smokers. The overall mean SSI rate was 10.8%, SSOPI rate was 12.7%, and 30-day readmission rate was 10.2%. ORACLE predictions correlated with observed SSI rates (OR 1.31, 95% CI 1.12-1.54, p < 0.001), but patient predictions did not (OR 1.00, 95% CI 0.98-1.03, p = 0.868). The correlation between patient predictions and ORACLE calculations was weak ([Formula: see text] = 0.17). Patient predictions were on average 10.1 ± 18.0% different than ORACLE, and 65% overestimated their SSI probability. Similarly, ORACLE predictions correlated with observed 30-day readmission rates (OR 1.10, 95% CI 1.00-1.21, p = 0.0459), but patient predictions did not (OR 1.00, 95% CI 0.975-1.03, p = 0.784). The correlation between patient predictions and ORACLE calculations for readmissions was weak ([Formula: see text] = 0.27). Patient predictions were on average 2.4 ± 14.6% different than ORACLE, and 56% underestimated their readmission probability. Additionally, a substantial proportion of the cohort believed that they had a 0% risk of SSI (28%) and a 0% risk of readmission (43%). Education, income and healthcare employment did not affect the accuracy of patient predictions.

CONCLUSIONS

Despite surgeon counseling, patients do not accurately estimate their risks after VHR when compared to ORACLE. Most patients overestimate their SSI risk and underestimate their 30-day readmission risk. Furthermore, several patients believed that they had a 0% risk of SSI and readmission. These findings persisted regardless of level of education, income level, or healthcare employment. Additional attention should be directed toward setting expectations prior to surgery and using applications such as ORACLE to assist in this process.

[Translated article] Translation, validation, and cultural adaptation of the HSS-ES scale (Hospital for Special Surgery's [HSS] Shoulder Surgery Expectations Survey)

INTRODUCTION

The questionnaire Hospital for Special Surgery Shoulder Surgery Expectations Survey (HSS-ES) is a tool used to assess the preoperative expectations of patients with shoulder pathologies. The purpose of this study is to translate, culturally adapt, and validate the Spanish version of the HSS-ES questionnaire to assess preoperative expectations in Spanish-speaking patients.

METHODOLOGY

Questionnaire validation study, using a structured method where a survey-type tool was processed, evaluated and validated. The study involved 70 patients from the shoulder surgery outpatient clinic of a tertiary care hospital, with shoulder pathologies requiring surgery.

RESULTS

The version of the questionnaire translated into Spanish presented a very good internal consistency with a Cronbach's Alpha of 0.94 and a very good reproducibility with an Intraclass Correlation Coefficient (ICC) of 0.99.

CONCLUSION

The HSS-ES questionnaire presents an adequate intragroup validation and a strong intergroup correlation according to the internal consistency analysis of the questionnaire and the ICC. Therefore, it is considered an adequate questionnaire to use in the Spanish-speaking population.

The Effects of Preoperative Pain Education on Pain Severity in Cardiac Surgery Patients: A Pilot Randomized Control Trial

BACKGROUND

There is minimal research on the effect of individualized preoperative education on postoperative pain and postoperative pain medication intake.

AIM

The study objective was to assess the effect of individually tailored preoperative education on postoperative pain severity, number of pain breakthroughs, and use of pain medication in participants receiving the intervention compared to controls.

METHODS

A pilot study with 200 participants was conducted. The experimental group received an informational booklet and discussed their ideas surrounding pain and pain medication with the researcher. Controls received no intervention. Postoperative pain severity was measured by a Numerical Rating System (NRS), which was divided into mild (NRS 1-3), moderate (NRS 4-6), and severe (NRS 7-10).

RESULTS

In the participant cohort, 68.8% of participants were male, and the average age was 60.48±10.7. Average postoperative 48-hour cumulative pain scores were lower in those who received the intervention compared to controls; 50.0 (IQR 35.8-60.0) vs. 65 (IQR 51.0-73.0; p < .01) participants who received the intervention had less frequent pain breakthroughs when compared to controls (3.0 [IQR 2.0-5.0] vs. 6.0 [IQR 4.0-8.0; p < .01]). There was no significant difference in the amount of pain medication taken by either group.

CONCLUSIONS

Participants who receive individualized preoperative pain education are more likely to have decreased postoperative pain.

Reverse Total Shoulder Arthroplasty for Proximal Humeral Fractures and Sequalae Compared to Non-Fracture Indications: A Matched Cohort Analysis of Outcome and Complications

Background: With the increase in utility and popularity of the reverse total shoulder arthroplasty (RTSA) within the last decades, indications for RTSA have expanded. As well as the established indications such as cuff tear arthropathy and massive irreparable rotator cuff tears, RTSA for complex proximal humeral fractures in elderly patients has been proven to be a reliable treatment option. Methods: A prospectively enrolled RTSA database of 1457 RTSAs implanted between September 2005 and November 2020 was reviewed. Patients treated with RTSA for a complex proximal humerus fracture and fracture sequalae (F-RTSA) were 1:1 matched with a group of patients who were treated electively with RTSA for indications other than a fracture (E-RTSA). Matching criteria included sex, age, length of follow-up and body mass index. Evaluation after a minimum of 2 years follow-up included evaluation of the absolute and relative Constant–Murley score (aCS; rCS), subjective shoulder value (SSV), range of motion (ROM) assessment and complications. Results: Each of the matched cohorts comprised 134 patients with a mean follow-up of 58 ± 41 months for the fracture group and 58 ± 36 months for the elective group. The mean age for both groups was 69 ± 11 years in the F-RTSA and 70 ± 9 years for the E-RTSA group. There were no significant differences in clinical outcome measures including aCS, rCS and SSV (p > 0.05). There was a significant difference in mean active external rotation with 20° ± 18° in the F-RTSA group compared with 25° ± 19° in the E-RTSA group (p = 0.017). The complication rate was not significantly different, with 41 complications in 36 shoulders in the F-RTSA and 40 complications in 32 shoulders in the E-RTSA group (p = 0.73). The main complication for the F-RTSA group was dislocation of the greater tuberosity (6%), whereas acromial fractures (9%) were the leading complication in the E-RTSA group. There was also no significant difference in revision rate comparing F-RTSA with E-RTSA (10% vs. 14%; p = 0.25). Conclusions: RTSA for complex proximal humeral fractures and its sequalae leads to a comparable clinical outcome as that for patients treated electively with RTSA for indications other than fracture. There was, however, a significant difference in active external rotation, with inferior rotation in patients undergoing RTSA for fracture. This valuable information can help in requesting informed consent of patients with proximal humeral fractures.

Optimizing Outcomes After Reverse Total Shoulder Arthroplasty: Rehabilitation, Expected Outcomes, and Maximizing Return to Activities

PURPOSE OF REVIEW

Given the touted clinical and patient-reported outcomes of reverse shoulder arthroplasty (RTSA) in improving pain and restoring function, shoulder surgeons are rapidly expanding the indications and utilization of RTSA. Despite its increasing use, the ideal post-operative management ensuring the best patient outcomes is still debated. This review synthesizes the current literature regarding the impact of post-operative immobilization and rehabilitation on clinical outcomes following RTSA including return to sport.

RECENT FINDINGS

Literature regarding the various facets of post-operative rehabilitation is heterogeneous in both methodology and quality. While most surgeons recommend 4-6 weeks of immobilization post-operatively, two recent prospective studies have shown that early motion following RTSA is both safe and effective with low complication rates and significant improvements in patient-reported outcome scores. Furthermore, no studies currently exist assessing the use of home-based therapy following RTSA. However, there is an ongoing prospective, randomized control trial assessing patient-reported and clinical outcomes which will help shed light on the clinical and economic value of home therapy. Finally, surgeons have varying opinions regarding return to higher level activities following RTSA. Despite no clear consensus, there is growing evidence that elderly patients are able to return to sport (e.g., golf, tennis) safely, though caution must be taken with younger or more high-functioning patients. While post-operative rehabilitation is believed to be essential to maximize outcomes following RTSA, there is a paucity of high-quality evidence that guides current rehabilitation protocols. There is no consensus regarding type of immobilization, timing of rehabilitation, or need for formal therapist-directed rehabilitation versus physician-guided home exercise. Additionally, surgeons have varied opinions regarding return to higher level activities and sports following RTSA. There is burgeoning evidence that elderly patients can return to sport safely, though caution must be taken with younger patients. Further research is needed to clarify the optimal rehabilitation protocols and return to sport guidelines.

Impact of cervical spine pathology on outcomes after total shoulder arthroplasty

BACKGROUND

Cervical spine pathology can affect the supporting muscles and function of the shoulder and contribute to shoulder and arm pain and hence may impact postoperative outcomes following shoulder arthroplasty. The purpose of this study was to evaluate the impact of a history of cervical spine arthrodesis and its timing, before or after total shoulder arthroplasty (TSA), on the outcomes of TSA. Our hypothesis is that a history of cervical arthrodesis (CA) will negatively impact patient outcomes after shoulder arthroplasty.

METHODS

A retrospective analysis was performed on a prospectively collected cohort at a single institution. Anatomic (aTSA) and reverse TSA (rTSA) patients with CA were identified and compared to a cohort of patients without CA (NCA) enrolled in an institutional registry from 2011 to 2020. Demographic characteristics, diagnoses, implant type, range of motion, adverse events, and clinical outcome metric scores (American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form [ASES], Constant, Shoulder Function score, patient satisfaction) were recorded. Outcomes between cohorts were analyzed using conventional statistics as well as stratification by minimal clinically important difference and substantial clinical benefit (SCB) thresholds where applicable.

RESULTS

Of the 573 TSAs evaluated, 48 (20a CA-aTSA and 28 CA-rTSA) had a history of CA and 525 (280 NCA-aTSA and 245 NCA-rTSA) had no history of CA. The CA-TSA (aTSA and rTSA) had lower Constant, ASES, and Shoulder Function scores postoperatively as well as less improvement in active external rotation and an overall lower satisfaction rating (P < .05 for all) compared with NCA-TSA. The adverse event rate in the CA-TSA cohort was higher compared with the NCA-TSA cohort (25% vs. 6.5% [rTSA; P = .004] and 24.5% vs. 11% [aTSA; P = .068]). Optimal cutoff analysis showed that a time from CA to TSA of greater than 1.33 years had a sensitivity of 75.0% and specificity of 75.0% in predicting achievement of SCB for ASES score.

CONCLUSION

The current study demonstrates that patients with a history of CA undergoing shoulder arthroplasty results in lower postoperative functional outcomes, lower satisfaction, and higher rates of postoperative adverse events requiring surgical revision when compared to a cohort without a history of CA. Additionally, the current study demonstrates that a time interval of at least 16 months between CA and shoulder arthroplasty optimizes the chances of achieving SCB for ASES score.

Higher preoperative expectations predict better outcomes in shoulder surgery patients

PURPOSE

The purpose of this study is to determine if preoperative expectations (PE) are an independent predictor of greater 2-year outcomes and greater improvement from baseline in shoulder surgery patients.

METHODS

Two-hundred and sixteen patients who underwent shoulder surgery at one institution were studied. Patients completed both preoperative and 2-year follow-up questionnaires including PROMIS (Patient-Reported Outcome Measurement Information System) computer-adaptive testing in six domains, American Shoulder and Elbow Surgeons (ASES) score, shoulder numeric pain scale (NPS), and the Marx Shoulder Activity Rating Scale (MARS). PE were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) expectations domain, and satisfaction was measured via the Surgical Satisfaction Questionnaire (SSQ-8).

RESULTS

The mean PE score was 86.2 ± 17.8. Greater PE were associated with significantly better 2-year scores for ASES, NPS, MARS, SSQ8, and PROMIS domains of Physical Function, Fatigue, Pain Interference Fatigue and Social Satisfaction. Multivariable analyses demonstrated that greater PE were an independent predictor of both better 2-year scores and greater improvement for PROMIS SS (p < 0.001), ASES (p = 0.007), and shoulder NPS (p = 0.011).

CONCLUSION

Greater PE are positively associated with numerous patient-based outcomes 2 years after surgery. With regards to pain relief, shoulder function, and social satisfaction, higher PE are also predictive of better outcome scores and more improvement. This study suggests that preoperative assessment of shoulder surgery PE is important, and that counseling patients to optimize realistic expectations may lead to superior outcomes.

Recall Bias in Retrospective Assessment of Preoperative American Shoulder and Elbow Surgeons Scores After Reverse Total Shoulder Arthroplasty

INTRODUCTION

Although reverse total shoulder arthroplasty (RTSA) has been shown to be effective for the treatment of cuff tear arthropathy (CTA), the patient's inability to accurately recall their preoperative shoulder condition could skew their perception of the effectiveness of the procedure. Identifying patients who are susceptible to notable recall bias before surgery can help surgeons counsel patients regarding expectations after surgery. The purpose of this study was to evaluate whether patients who undergo RTSA are susceptible to recall bias and, if so, which factors are associated with poor recollection.

METHODS

Patients who underwent RTSA for CTA by the senior author between September 2016 and September 2018 were identified. All patients completed the American Shoulder and Elbow Surgeons (ASES scores) Standardized Assessment Form at the time of preoperative assessment. Patients were contacted at a minimum of 24 months after surgery to retrospectively assess their preoperative condition.

RESULTS

A total of 72 patients with a mean age of 72.2 ± 7.65 years completed a retrospective shoulder assessment at 28.3 ± 7.3 months postoperatively. Patient assessment of shoulder condition showed poor reliability (intraclass correlation coefficient = 0.453, confidence interval, 0.237-0.623). Greater preoperative shoulder ASES scores were associated with a greater difference between preoperative ASES scores and recall ASES scores (β = 0.275, P < 0.001).

CONCLUSION

Patients who undergo RTSA for CTA are susceptible to clinically significant recall bias. Patients with better preoperative condition recall worse preoperative shoulder conditions compared with patients with worse preoperative conditions and are susceptible to a higher degree of recall bias. This patient population should be identified preoperatively and have notable counseling before and after surgery to help them better understand their disease burden and what to expect after surgical intervention.

Characterizing preoperative expectations for patients undergoing reverse total shoulder arthroplasty

BACKGROUND

There remains a paucity of information analyzing which factors most influence preoperative expectations for patients undergoing reverse total shoulder arthroplasty (RTSA). The purposes of our study were to characterize preoperative patient expectations for those scheduled to undergo RTSA and to determine the impact of demographic factors, shoulder function, and shoulder pain on these preoperative expectations.

METHODS

Patients were prospectively recruited into the study if they were scheduled to undergo an elective unilateral primary RTSA for a diagnosis of glenohumeral arthritis. Preoperative patient expectations were evaluated using the Hospital for Special Surgery's Shoulder Surgery Expectation Survey. Patients also completed the American Shoulder and Elbow Surgeons shoulder score, the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function-Upper Extremity computer adaptive test (version 2.0), the PROMIS Pain Interference (PI) computer adaptive test (version 1.1), the PROMIS Depression computer adaptive test (version 1.0), visual analog scores, and an itemized satisfaction questionnaire, which paralleled the Hospital for Special Surgery's Shoulder Surgery Expectation Survey. Demographic data and preoperative shoulder range of motion (ROM) were also recorded.

RESULTS

A total of 107 patients scheduled to undergo RTSA were included in the study. Relief of daytime pain (n = 91, 85%), improvement in self-care (n = 86, 80%), and improvement in shoulder ROM (n = 85, 79%) were most commonly cited as "very important" expectations. In the item-specific analysis, lower PROMIS Upper Extremity scores were correlated with greater expectations for the ability to reach sideways (P = .015) and the ability to perform daily activities (P = .018). Patients with lower shoulder ROM had greater expectations for improved shoulder ROM (internal rotation with arm at 90°, P = .004) and an improved ability to perform daily activities (forward elevation, P = .038; abduction, P = .009). In the cumulative analysis, a greater number of very important expectations was associated with African American race (P = .013), higher PROMIS PI score (r = 0.351, P = .004), and lower overall preoperative satisfaction (r = 0.334, P < .001).

CONCLUSION

Patients scheduled to undergo RTSA have the greatest expectations for relief of daytime pain, improvement in self-care, and improvement in shoulder ROM. Patients with limited preoperative ROM have greater expectations for improvement in self-care and the ability to perform daily activities in addition to expectations for improvement in shoulder ROM. Greater overall expectations for surgery were not associated with preoperative physical function but were instead associated with lower preoperative satisfaction and higher PROMIS PI scores.

Outcomes of shoulder arthroplasty by year of index procedure: are we getting better?

BACKGROUND

The purpose of this study was to determine whether postoperative patient-reported outcomes improved over time following anatomic total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA).

METHODS

We performed a retrospective analysis of prospectively collected patient-reported outcomes from our institution's registry between 2008 and 2018 (N = 1899). American Shoulder and Elbow Surgeons (ASES) scores at a minimum of 2 years postoperatively were required. Univariable linear models were used to test the association between year of surgery and improvement in ASES scores at 2- and 5-year follow-up, as well as any association with age, sex, primary or revision surgery, hand dominance, American Society of Anesthesiologists classification, rotator cuff status, primary diagnosis, and Walch classification. Multivariable models were created to analyze ASES score improvement by index year while controlling for significant factors.

RESULTS

In the univariable analysis, 5-year ASES difference scores increased each year by a mean of 1.65 (P < .001; 95% confidence interval [CI], 0.75-2.55) for TSA, 2.50 (P = .014; 95% CI, 0.52-4.49) for RTSA, and 1.64 (P < .001; 95% CI, 0.81-2.47) for the overall population. Patient sex, American Society of Anesthesiologists classification, rotator cuff status, primary diagnosis, Walch classification, and revision procedures were also significant factors affecting ASES scores. On multivariable analysis controlling for these factors, 5-year ASES difference scores were still significantly associated with year of surgery, increasing each year by a mean of 2.20 (P < .001; 95% CI, 0.91-3.50) for TSA, 4.83 (P < .001; 95% CI, 1.17-8.49) for RTSA, and 1.66 (P < .001; 95% CI, 0.81-2.51) for the entire population.

CONCLUSION

Both anatomic TSA and RTSA patients reported increasing ASES difference scores at 5-year follow-up as time passed. These findings may indicate that advances in shoulder arthroplasty have resulted in better patient outcomes over time. Further research is needed to clarify which factors influence improvements in outcomes, particularly for revision procedures.

Does preoperative disease severity influence outcomes in reverse shoulder arthroplasty for cuff tear arthropathy?

BACKGROUND

The degree of symptomatic disease and functional burden has been demonstrated to influence patient results and satisfaction in total hip and knee arthroplasty. Although the relationship between preoperative diagnosis and patient outcomes has been an area of study for reverse total shoulder arthroplasty (RTSA), the influence of the progression of cuff tear arthropathy (CTA) has not yet been examined. The purpose of this study was to evaluate whether preoperative radiographic disease burden and scapular geometry impact patient outcomes and satisfaction in a cohort of patients with CTA treated with RTSA.

METHODS

Eighty-six patients were treated for CTA with RTSA performed by the senior author (B.G.) between September 2016 and September 2018 and were enrolled in an institutional registry. At the time of initial evaluation, the baseline American Shoulder and Elbow Surgeons (ASES) score, patient demographic characteristics, history of shoulder surgery, and presence of pseudoparalysis were collected. Radiographs were obtained to evaluate the critical shoulder angle, acromial index, and progression of CTA as assessed by Hamada grading and the Seebauer classification. Patients were contacted to reassess the ASES score and their satisfaction with the improvement in their shoulder function.

RESULTS

A total of 79 patients (91.6%) were available for evaluation at a minimum of 24 months of follow-up. Multivariate logistic regression modeling revealed that scapular geometry measurements (critical shoulder angle and acromial index) and the degree of CTA (Seebauer and Hamada classifications) were not associated with worse outcomes as assessed by the ASES score. However, degenerative changes as assessed by the Hamada grade (odds ratio, 0.13 [95% confidence interval, 0.02-0.86]; P = .03) and preoperative ASES score (odds ratio, 1.04 [95% confidence interval, 1.01-1.07]; P = .008) were independently associated with higher satisfaction at 24 months of follow-up.

CONCLUSION

The results indicate that patients with greater CTA disease progression did not show differing outcomes after RTSA compared with patients with milder disease. In contrast, both poorer preoperative function and degenerative changes as assessed by the Hamada classification were associated with greater satisfaction after RTSA for CTA. Given the broad spectrum of disease in CTA, there is likely a corresponding range in patient expectations that requires further study to maximize patient satisfaction.

Why patients fail to achieve a Patient Acceptable Symptom State (PASS) after total shoulder arthroplasty?

Background

The purpose of this study was to compare patient-reported outcomes (PROs) and range of motion (ROM) measurements between patients achieving and failing to achieve a Patient Acceptable Symptom State (PASS) after anatomic total shoulder arthroplasty (TSA) to determine which PRO questions and ROM measurements were the primary drivers of poor outcomes.

Methods

A retrospective review of a multicenter database identified 301 patients who had undergone primary TSA between 2015 and 2018 with ROM and PRO data recorded preoperatively and at a minimum of two years postoperatively. The primary outcome was the difference in active ROM between patients achieving and failing to achieve the PASS threshold for the American Shoulder and Elbow Surgeons (ASES) and Single Assessment Numeric Evaluation (SANE) scores. The secondary outcome was the difference in self-reported pain levels between those achieving and failing to achieve a PASS.

Results

Based on the ASES PASS threshold, 87% (261/301) of patients achieved a PASS after TSA, whereas 13% did not. Based on the SANE PASS threshold, 69% (208/301) of patients achieved a PASS after TSA, whereas 31% did not. Patients who failed to achieve a PASS after TSA were younger and had lower short form-12 mental health scores than those who did. There was a significant difference in pain between those who achieved and failed to achieve a PASS after TSA (ASES PASS current shoulder pain 16.5% vs. 95%, P < .001, SANE PASS current shoulder pain 13% vs. 58.1%, P < .001). Those failing to reach a PASS had significantly higher pain levels (ASES PASS Visual Analog Scale pain scores [4.2 vs. 0.4, P < .001] and SANE PASS Visual Analog Scale pain scores [2.0 vs. 0.4, P < .001]) and worse function in nearly all domains of the ASES and Western Ontario Osteoarthritis of the Shoulder index after surgery. There was little difference in ROM between those reaching and failing to reach a PASS (no difference in active external rotation with the arm adducted, active internal rotation at the nearest spinal level, or active internal rotation with the shoulder abducted to 90 degrees for ASES and SANE PASS).

Conclusion

There is variability in the percentage of patients who achieve a PASS after TSA, ranging from 69% to 87% depending on the PRO used to define the threshold. Patients who did not achieve a PASS after TSA were significantly more likely to have pain, whereas there were very few differences in ROM, indicating pain as the primary driver of failing to achieve a PASS. Setting realistic postoperative expectations for pain relief may be important for improving patient-reported results after TSA.

Glenoid lateralization influences active internal rotation after reverse shoulder arthroplasty

BACKGROUND

Improvement in internal rotation (IR) is not reliably achieved after reverse total shoulder arthroplasty (RSA). The purpose of this study was to evaluate the relationship between postoperative IR and glenoid-sided lateralization following RSA in an implant using metallic lateralization.

METHODS

A multicenter retrospective study of RSAs with minimum 1-year clinical follow-up was performed. Patients were stratified based on the amount of glenoid-sided implant lateralization into 4 groups: 0-2 mm (n = 57), 4 mm (n =238), 6 mm (n = 95), and 8 mm (n = 65). The primary study outcome was active IR at a minimum of 1 year postoperatively, measured both by spinal level and in degrees with the shoulder abducted to 90°. Secondary outcomes were active forward flexion and external rotation, belly press strength, and subjective patient-reported outcome (PRO) measures. Comparisons were made with 1-way analyses of variance. Linear regression analyses evaluating for the association of glenoid lateralization with active IR were also performed to control for additional confounders, including demographics and other implant variables such as glenosphere diameter, humeral lateralization, humeral version, and whether the subscapularis was repaired.

RESULTS

A total of 455 patients were included in the study. The mean age was 69 years, and 48% of patients were male. IR differences varied by the method of measurement (spinal level vs. IR in degrees with arm abducted). Overall, patients with 8 mm of glenoid lateralization had significantly improved IR compared with all other lateralization groups. Patients with 6 mm of glenoid lateralization had significantly improved IR compared with the 0-2- and 4-mm groups. There were no significant differences in the secondary outcomes or PROs between lateralization groups. In the regression analysis, glenoid lateralization was the only implant-related variable that was significantly associated with improved IR for both measurement methods. Glenosphere diameter and humeral version were both significantly associated with IR measured in degrees with the arm abducted but not spinal level.

CONCLUSIONS

For the studied implant system, glenoid lateralization of 6-8 mm was associated with improved active IR at 1 year compared to patients with less glenoid lateralization with no significant differences in active forward flexion, external rotation, or PROs. In a multivariable analysis, increased humeral retroversion was associated with increased IR at 90° and increasing glenosphere diameter was associated with decreased IR at 90°, whereas BMI, subscapularis repair, and humeral lateralization did not significantly affect active IR.

Evaluation of Patient Expectations before Carpal Tunnel Release

Background:

Carpal tunnel release (CTR) is common, yet patient treatment expectations remain unclear. The primary purpose was to describe patient expectations before CTR. Secondarily, we aimed to identify factors influencing expectations.

Methods:

Included patients underwent unilateral or bilateral CTR between 2015 and 2017 at a single academic center. Expectations regarding the level of relief/improvement were queried. Area deprivation index (ADI) was used to measure social deprivation. Univariate and multivariable logistic regression identified factors associated with expecting great relief/improvement.

Results:

Of 307 included patients, mean age was 54 ± 16 years and 63% were women. Patients most commonly expected great (58%) or some (23%) relief/improvement. Few patients expected little (3%) or no (4%) relief/improvement, and 13% had no expectations. In the multivariable analysis, male sex, lower social deprivation, and lower BMI were associated with expecting great relief/improvement. Age, surgical technique (open versus endoscopic), use of the operating room versus procedure room, and preoperative factors (constant numbness, weakness/atrophy, duration of symptoms, and QuickDASH) were not associated with expectations.

Conclusions:

Most patients expect some to great improvement after CTR. This was independent of several factors with a known association with worse outcomes (advanced age, atrophy/weakness, and constant numbness). Male sex was associated with the expectation of great improvement, in which superior outcomes relative to females have not been borne out in the literature. These findings highlight patient counseling opportunities. The observed association between social deprivation and expectations warrants further investigation, as the socioeconomically disadvantaged experience worse healthcare outcomes in general.

Prospective Comparative Study of Preoperative Expectations and Postoperative Outcomes in Anatomic and Reverse Shoulder Arthroplasty

Background  Compared with anatomic total shoulder arthroplasty (aTSA), reverse total shoulder arthroplasty (RTSA) is associated with lower preoperative and postoperative outcome scores and range of motion. It is unknown whether patients' preoperative expectations of surgery are lower in RTSA compared with aTSA. The purpose of this study was to assess preoperative patient expectations and postoperative outcomes in aTSA and RTSA. Methods  A consecutive series of patients undergoing primary aTSA for diagnosis of osteoarthritis or primary RTSA for diagnosis of rotator cuff tear arthropathy were studied prospectively. Expectations were evaluated using the validated Hospital for Special Surgery's Shoulder Surgery Expectations Survey. Baseline demographics, comorbidities, and social factors were collected. Baseline and 2 years postoperative American Shoulder and Elbow Surgeons (ASES) score, visual analog scale pain, Single Assessment Number Evaluation (SANE), and patient satisfaction were obtained. Results  There were 128 patients (64 aTSA and 64 RTSA). There was no significant difference in total preoperative expectations score between groups. On multivariate linear regression analysis, aTSA ( p  = 0.024) and younger age ( p  = 0.018) were associated with higher expectations for improved ability to exercise. Changes in preoperative to postoperative ASES ( p  = 0.004) and SANE ( p  = 0.001) scores were higher in the aTSA group. Total preoperative expectations score was not correlated with postoperative functional outcomes or satisfaction in either group. In the aTSA group, expectations for participation in exercise were positively correlated with changes in preoperative to postoperative ASES score ( p  = 0.01) and SANE score ( p  = 0.01). Conclusion  Though patients undergoing primary aTSA demonstrated greater improvement in functional outcome than those undergoing primary RTSA, both groups reported similar aggregate preoperative expectations. Those undergoing aTSA had higher expectations for return to exercise which was positively correlated with postoperative functional outcomes. Level of Evidence  Level II, prospective cohort study.

Preoperative Expectations of Patients Undergoing Knee Surgery

There is limited validated data regarding the relationship between preoperative expectations and patient-reported outcomes (PROs) in patients undergoing knee surgery. The purpose of this study was to (1) assess the preoperative expectations of patients undergoing knee surgery and (2) determine the relationship between preoperative patient demographics, PROs, and preoperative patient expectations. We hypothesized that younger patients with worse function and worse general health status would have greater expectations of knee surgery. We analyzed data from 399 patients undergoing knee surgery at an urban academic medical center. We utilized the Musculoskeletal Outcomes Data Evaluation and Management System to measure preoperative expectations. Multiple legacy PRO measures were recorded, as well as the new Patient-Reported Outcomes Measurement Information Systems (PROMIS) Computer Adaptive Testing. Nonparametric statistical analyses were performed to determine significance. Overall, patients undergoing knee surgery had high expectations, with a mean of 88.0 (95% confidence interval [CI], 86.7-89.3) and median of 91.7 (95% CI, 89.2-94.3). Greater preoperative expectations of knee surgery were associated with higher income, surgically naïve knee, lower Charlson Comorbidity Index, better PROMIS Depression and Anxiety scores, greater Marx knee activity scores, and lower total body pain (p < 0.05). Preoperative expectations of patients undergoing knee surgery are associated with a history of prior knee surgery, income, general and mental health, activity, and pain. Expectations were also found to be associated with PRO measures of function and psychological well-being. These findings may have implications for patient education and shared decision-making preoperatively. The level of evidence for the study is IV.

Reverse total shoulder arthroplasty clinical and patient-reported outcomes and complications stratified by preoperative diagnosis: a systematic review

OBJECTIVE

This systematic review aimed to investigate differences in clinical outcomes, patient-reported outcomes (PROs), and complication types and rates among preoperative diagnoses following reverse total shoulder arthroplasty (RTSA): rotator cuff tear arthropathy, primary osteoarthritis, massive irreparable rotator cuff tear, proximal humeral fracture, rheumatoid arthritis (RA), and revision of anatomic arthroplasty (Rev).

LITERATURE SEARCH

Three electronic databases were searched from inception to January 2020.

STUDY SELECTION CRITERIA

The inclusion criteria were (1) patients with a minimum age of 60 years who underwent RTSA for the stated preoperative diagnoses, (2) a minimum of 2 years' follow-up, and (3) preoperative and postoperative values for clinical outcomes and PROs.

DATA SYNTHESIS

Risk of bias was determined by the Methodological Index for Non-randomized Studies tool and the modified Downs and Black tool. Weighted means for clinical outcomes and PROs were calculated for each preoperative diagnosis.

RESULTS

A total of 53 studies were included, of which 36 (68%) were level IV retrospective case series. According to the Methodological Index for Non-randomized Studies tool, 33 studies (62%) showed a high risk of bias; the 3 randomized controlled trials showed a low risk of bias on the modified Downs and Black tool. RTSA improved clinical outcomes and PROs for all preoperative diagnoses. The Rev group had poorer final outcomes as noted by a lower American Shoulder and Elbow Surgeons score (69) and lower pain score (1.8) compared with the other preoperative diagnoses (78-82 and 0.4-1.4, respectively). The RA group showed the highest complication rate (28%), whereas the osteoarthritis group showed the lowest rate (1.4%).

CONCLUSION

Studies in the RTSA literature predominantly showed a high risk of bias. All preoperative diagnoses showed improvements; Rev patients showed the worse clinical outcomes and PROs, and RA patients showed higher complication rates. The preoperative diagnosis in RTSA patients can impact outcomes and complications.

Machine Learning Can Predict Level of Improvement in Shoulder Arthroplasty

The ability to accurately predict postoperative outcomes is of considerable interest in the field of orthopaedic surgery. Machine learning has been used as a form of predictive modeling in multiple health-care settings. The purpose of the current study was to determine whether machine learning algorithms using preoperative data can predict improvement in American Shoulder and Elbow Surgeons (ASES) scores for patients with glenohumeral osteoarthritis (OA) at a minimum of 2 years after shoulder arthroplasty.

Reverse total shoulder arthroplasty for patients with minimal preoperative pain: a matched-cohort analysis

BACKGROUND

Profound improvements in function have been described in patients following reverse total shoulder arthroplasty (RSA). Previous studies have demonstrated young age, high preoperative function, and neurologic dysfunction to be predictors of poor functional improvement. However, no study to date has focused on patients electing to undergo RSA for function more than pain. The purpose of this study was to compare the outcomes of RSA in patients with minimal preoperative pain with those in patients who have higher baseline pain.

METHODS

We performed a retrospective matched-cohort study of RSA patients treated by a single surgeon with a minimum of 2 years' follow-up. Patients with at least moderate baseline pain (function-pain group), predefined by existing literature as a visual analog scale pain score > 3, were matched 3:1 based on sex, indication, and age to patients with minimal pain (function group), defined as a visual analog scale score ≤ 3. Patient-reported outcome measures, active range of motion, and overall satisfaction were compared. The percentage of maximal improvement in outcomes and the proportion of patients exceeding the established threshold that predicts excellent satisfaction were also compared.

RESULTS

A total of 260 patients (195 in function-pain group and 65 in function group) were selected for matched analysis with a similar sex distribution; the mean age was 73.1 years, and the mean follow-up period was 50 months. No differences in most recent postoperative function, overall improvement in functional scores, and active motion were found between patients in the 2 groups (P > .05). However, pain scores improved only in patients with at least moderate baseline pain (P < .0001). Patient satisfaction was significantly different (P = .035), as 10.8% of patients who elected to undergo RSA for function were unsatisfied. The function cohort also had worse percentage of maximal Simple Shoulder Test score (P = .034) and American Shoulder and Elbow Surgeons score (P < .0001) improvement, and a lower proportion of these patients exceeded the threshold for the percentage of maximal improvement that predicts an "excellent" outcome (P < .0001).

CONCLUSION

RSA patients with minimal preoperative pain achieve significant improvements in function and motion similar to those who choose to undergo RSA for both pain and function, but they are less satisfied and are less likely to achieve an excellent outcome. Patients electing to proceed with RSA with minimal pain should be counseled accordingly.

Resilience correlates with patient reported outcomes after reverse total shoulder arthroplasty

BACKGROUND

Personal and social factors may account for much of the variation in patient reported outcome scores, yet little evidence exists on how psychological properties affect patient outcomes following reverse total shoulder arthroplasty (rTSA). The objective of this study is to determine if resilience, characterised by the ability to return to a healthy level of function after experiencing stress, correlates with patient reported outcome scores after rTSA.

HYPOTHESIS

Resilience score will correlate positively with patient reported outcomes after rTSA.

METHODS

Seventy-three patients were identified that had undergone primary rTSA with minimum 2-year follow-up (4.7±1.8). These patients completed a phone survey that included the Brief Resilience Scale (BRS), a measure of general resilience in all aspects of life, along with American Shoulder and Elbow Surgeon (ASES), Penn, and Single Assessment Numerical Evaluation (SANE) scores. Mean outcome scores were calculated to identify any correlation between resilience and clinical outcomes.

RESULTS

The mean BRS score was 23.8±4.8 (range 12.0-30.0), with 41 patients classified as normal resilience (NR), 17 patients as low resilience (LR), and 15 as high resilience (HR). Postoperative BRS scores correlated with ASES (r=0.31, p=0.008), Penn (r=0.25, p=0.03), and SANE score (r=0.32, p=0.007). The mean ASES score was 14.0 points lower in the LR group (77.0 points), compared to the HR group (91.0 points; p=0.04). Similarly, the LR group had a mean SANE score that was 18.6 points lower than the HR group (73.4 and 91.9 points, respectively; p=0.021).

DISCUSSION

The observation that greater general life resilience correlates with lower pain intensity, lesser magnitude of limitations, and perception of greater normality of the shoulder after reverse total shoulder arthroplasty emphasises the importance of addressing personal and social health opportunities along with the physical in musculoskeletal care. Resilience may be a useful predictor of outcomes following rTSA.

Outcomes after a Grammont-style reverse total shoulder arthroplasty?

BACKGROUND

The purpose of this study was to determine the factors associated with outcomes after reverse total shoulder arthroplasty (RTSA).

METHODS

We retrospectively evaluated all RTSAs performed by the senior author between January 1, 2007, and November 1, 2017. We evaluated pain visual analog scale (VAS), Simple Shoulder Test (SST), and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores and complication and reoperation rates at a minimum of 2-year follow-up. We evaluated preoperative and 2-week postoperative radiographs for glenoid inclination (GI), medialization as distance between the center of the humeral head or glenosphere and the line of the deltoid, and distalization via the acromial-greater tuberosity distance. We performed inter- and intrarater reliabilities via intraclass correlation coefficients (ICCs) and conducted a multivariable analysis.

RESULTS

We included 230 RTSAs in the analysis, with 70% follow-up at a median of 3.4 years. Reliability was acceptable with all ICCs >.678. Increased postoperative GI was significantly associated with increased VAS pain postoperatively (P = .008). Increased distalization was associated with an increased rate of complications and reoperations (P = .032). Younger age (P = .008), female gender (P = .009), and lower body mass index (BMI) (P = .006) were associated with worse ASES scores. Female gender (P < .001) and lower BMI (P = .039) were associated with worse SST scores. Female gender (P = .013) and lower BMI (P = .005) were associated with worse VAS-pain scores.

CONCLUSION

Age, gender, and BMI are associated with outcome after RTSA. In this retrospective analysis of a Grammont-style RTSA, superior inclination is associated with increased pain postoperatively, whereas excessive arm lengthening is associated with increased risk for complication or reoperation.

Psychosocial factors affecting outcomes after shoulder arthroplasty: a systematic review

BACKGROUND

Both anatomic and reverse total shoulder arthroplasty are considered successful surgeries to treat a variety of painful shoulder conditions. Although implant survivorship for both is good to excellent in the long term, a variety of factors-clinical, technical, and psychosocial-may affect patient-reported outcomes after shoulder arthroplasty.

METHODS

A comprehensive review of the literature was performed systematically using keywords "shoulder arthroplasty outcomes," "psychosocial factors shoulder," "shoulder replacement outcomes," "depression shoulder arthroplasty," "satisfaction shoulder arthroplasty," "factors shoulder replacement," "expectations shoulder arthroplasty," and "predictors shoulder arthroplasty." Studies meeting the inclusion criteria were screened and analyzed. Type of surgery performed, sample size, outcome measures, and other factors influencing patient outcomes were recorded and analyzed.

RESULTS

Sixteen studies met the inclusion criteria. Six reviewed mental health disorders as predictors of postoperative outcome after shoulder arthroplasty. Of these, 4 found that disorders such a depression and anxiety were associated with increased risk of perioperative complications and lower final functional outcome scores. Two studies evaluated workers' compensation status as a possible predictor of outcomes and found that patients with claims had lower satisfaction and outcome scores at final follow-up compared with those without claims. Two studies showed that preoperative opioid use was associated with lower outcome scores and overall satisfaction rate after shoulder arthroplasty. Three studies showed that higher patient confidence and preoperative expectations were correlated with better outcomes.

CONCLUSION

Our review shows that psychosocial factors may play just as important role in affecting patient outcomes after total shoulder arthroplasty as technical factors.

Improvement in sleep quality after total shoulder arthroplasty

Objective: Poor sleep quality due to nocturnal pain is increasingly reported as a major symptom in advanced glenohumeral arthritis. The current study aimed to evaluate preoperative and postoperative sleep quality, shoulder pain, and function in patients who underwent total shoulder arthroplasty (TSA). Preoperative factors contributing to delayed improvements in sleep quality were examined.Methods: Patients scheduled for anatomic or reverse TSA due to glenohumeral arthritis were included. Patients completed the Pittsburgh Sleep Quality Index (PSQI) and American Shoulder and Elbow Surgeons (ASES) survey preoperatively, and at 6 weeks, 3 months, 6 months, and 1 year following surgery. A higher PSQI score (maximum 21) indicated greater sleep disturbance.Results: Seventy-four patients (34 males, 40 females), with a mean age of 65.8 years were prospectively enrolled. Eighty-four percent of patients reported preoperative PSQI scores indicative of sleep disturbance (6 or greater), with a mean of 10.1 ± 4.3. The PSQI score significantly improved to 7.7 at 6 weeks (P = .003), and to 6.1 at 3 months (P = .08). At 12 months, the PSQI was within normal limits (less than or equal to 5) with a mean score of 4.3. A normal PSQI score was achieved by 40.8%, at 6 weeks, 50% at 3 months, 53.7% at 6 months, and 73.9% at 1 year. The ASES score significantly improved from 32.6 ± 17.2 at baseline to 58.4 at 6 weeks (p < .001), 76.1 at 3 months (p < .001), and 85.3 at 12 months. Linear regression demonstrated that the ASES and PSQI scores were negatively associated with each other at each time point. Body mass index and female gender were associated with a delayed return to baseline sleep quality.Conclusion: Shoulder-related sleep disturbance significantly improved at 6 weeks following TSA, and normalized for most patients by 1 year post-operatively. Enhanced sleep quality after TSA was directly related to improved functional outcomes.

Pre-operative factors affecting the indications for anatomical and reverse total shoulder arthroplasty in primary osteoarthritis and outcome comparison in patients aged seventy years and older

BACKGROUND

We evaluated the pre-operative factors affecting anatomical and reverse total shoulder arthroplasty (TSA and RTSA) indications in primary osteoarthritis and compared outcomes in patients aged 70 years and older.

METHODS

Fifty-eight patients received a TSA with an all-polyethylene glenoid component (APGC) or an RTSA with/without glenoid lateralization and the same curved short-stem humeral component. Active anterior and lateral elevation (AAE, ALE), internal and external rotation (IR, ER), pain, and the Constant-Murley score (CS) were recorded pre and post-operatively. Pre-operative rotator cuff (RC) fatty infiltration (FI) and modified Walch glenoid morphology were assessed. Humeral and glenoid component radiological outcomes were recorded.

RESULTS

RTSA were older than TSA patients (p = 0.006), had lower pre-operative AAE (p < 0.001), ALE (p < 0.001), IR (p = 0.002), pain (p = 0.008) and CS (p < 0.001), and greater supraspinatus FI (p < 0.001). At a mean of 28.8 months, both implants yielded significantly different post-operative scores and similar complication rates. Both groups achieved similar post-operative AAE, ER, and IR; ALE was higher in TSA (p = 0.006); and AAE and ALE delta scores were higher in RTSA (p = 0.045 and p = 0.033, respectively). Radiolucent line rates were higher around the TSA APGC than the RTSA baseplate (p = 0.001). High-grade RC FI adversely affected mobility improvement. Humeral cortical thinning was significantly higher in TSA (p = 0.001).

CONCLUSION

RTSA patients were older, had poorer pre-operative active mobility, and had greater RC FI than TSA. Both devices provided good mid-term clinical and ROM improvement.

Predictors of patient satisfaction after reverse shoulder arthroplasty

HYPOTHESIS

The aims of this study were to determine patient satisfaction and to identify predictors of satisfaction after reverse shoulder arthroplasty (RSA). We hypothesized that the majority of patients would be satisfied after RSA and that patients with worse preoperative mental and physical health would be less satisfied.

METHODS

Satisfaction was assessed 2 years after primary RSA with domains for pain, work, activities, quality of life, and overall satisfaction. Preoperative and postoperative patient-reported factors were measured using the American Shoulder and Elbow Surgeons (ASES) shoulder score, Shoulder Activity Scale score, Short Form 12 (SF-12) mental and physical component summary scores, and visual analog scale (VAS) pain, fatigue, and general health scores. Pearson correlations were used to determine the relationship between patient-reported factors and satisfaction. Multivariate regression was performed to control for potential confounding variables.

RESULTS

A total of 161 patients were evaluated at 2 years postoperatively. Patients were "very satisfied" in an average of 3.3 of the 5 domains. Improvements in ASES, Shoulder Activity Scale, VAS pain, and SF-12 physical component summary scores were associated with higher satisfaction, with correlation coefficients ranging from 0.27 to 0.49. On multivariate analysis, patients with higher preoperative ASES scores were less satisfied after surgery (P = .005). In addition, patients with worse VAS fatigue (P = .011) and SF-12 mental (P = .034) and physical (0.011) component summary scores preoperatively had lower satisfaction.

CONCLUSION

Improvements in pain and outcome scores are associated with increased satisfaction. Patients with higher shoulder function, worse physical health, and worse mental health prior to surgery are more likely to have lower satisfaction after RSA.

Optimizing opioid prescribing and pain treatment for surgery: Review and conceptual framework

Purpose

Millions of Americans who undergo surgical procedures receive opioid prescriptions as they return home. While some derive great benefit from these medicines, others experience adverse events, convert to chronic opioid use, or have unused medicines that serve as a reservoir for potential nonmedical use. Our aim was to investigate concepts and methods relevant to optimal opioid prescribing and pain treatment in the perioperative period.

Methods

We reviewed existing literature for trials on factors that influence opioid prescribing and optimization of pain treatment for surgical procedures and generated a conceptual framework to guide future quality, safety, and research efforts.

Results

Opioid prescribing and pain treatment after discharge from surgery broadly consist of 3 key interacting perspectives, including those of the patient, the perioperative team, and, serving in an essential role for all patients, the pharmacist. Systems-based factors, ranging from the organizational environment’s ability to provide multimodal analgesia and participation in enhanced recovery after surgery programs to other healthcare system and macro-level trends, shape these interactions and influence opioid-related safety outcomes.

Conclusions

The severity and persistence of the opioid crisis underscore the urgent need for interventions to improve postoperative prescription opioid use in the United States. Such interventions are likely to be most effective, with the fewest unintended consequences, if based on sound evidence and built on multidisciplinary efforts that include pharmacists, nurses, surgeons, anesthesiologists, and the patient. Future studies have the potential to identify the optimal amount to prescribe, improve patient-focused safety and quality outcomes, and help curb the oversupply of opioids that contributes to the most pressing public health crisis of our time.

Preoperative patient expectations of elective reverse shoulder arthroplasty

BACKGROUND

The purpose of this study was to determine patients' preoperative expectations before primary elective reverse shoulder arthroplasty (RSA). We hypothesized that younger patients, patients with better preoperative function, patients with shoulder osteoarthritis (OA), and patients with no prior joint replacements would have higher expectations of RSA.

METHODS

We prospectively studied 333 primary RSAs performed for cuff tear arthropathy (n = 242), OA (n = 68), or post-traumatic arthritis (n = 23). Expectations were assessed preoperatively using the Hospital for Special Surgery's shoulder surgery expectations survey. Preoperative patient-reported measures were assessed with the American Shoulder and Elbow Surgeons shoulder score; Shoulder Activity Scale score; Short Form 12 mental component and physical component scores; and visual analog scale scores for pain, fatigue, and general health. A Poisson regression model was performed to control for potential confounding variables.

RESULTS

Relief of night-time pain, relief of daytime pain, improvement in self-care, improvement in the ability to drive or put on a seat belt, and improvement in the ability to perform daily activities were reported as "very important" by approximately half of patients. No association was found between age and overall expectations. Multivariate analysis showed that better preoperative Shoulder Activity Scale and Short Form 12 physical component scores were associated with greater expectations (P < .001). OA was associated with greater expectations compared with cuff tear arthropathy (P < .001). A history of either contralateral RSA or any joint replacement was associated with lower expectations (P < .001).

CONCLUSION

Patients have the highest expectations for pain relief and the performance of simple tasks after RSA. Patients with higher preoperative function, OA, and no previous joint replacements have greater expectations of RSA.

Does having a rotator cuff repair prior to reverse total shoulder arthroplasty influence the outcome?

Aims

The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair.

Patients and Methods

All patients with a history of rotator cuff repair who underwent RSA between 2000 and 2015 with a minimum follow-up of two years were eligible for inclusion as the study group. Outcomes, including the American Shoulder and Elbow Surgeons (ASES) scores, were compared with a matched control group of patients who underwent RSA without having previously undergone rotator cuff repair.

Results

The study group included 45 patients. Their mean age was 69 years (sd 8.6) and 27 patients (60%) were women. The mean ASES score improved from 43.1 to 76.6 two years postoperatively, and to 66.9 five years postoperatively. There was no significant difference between the outcomes at two years in the two groups (all p ≥ 0.05), although there was significantly more improvement in ASES scores in the control group (44.5 vs 33.4; p = 0.01). However, there was no significant difference between ASES scores at two and five years when baseline ASES scores were matched in the two groups (p = 0.42 at two years; p = 0.35 at five years).

Conclusion

Significant improvements in ASES scores were seen following RSA in patients who had previously undergone rotator cuff repair. They had higher baseline ASES scores than those who had not previously undergone this surgery. However, there was no significant difference in outcomes between the two groups, two years postoperatively. Previous rotator cuff repair does not appear to affect the early outcome after RSA adversely.
