Abstract

Background

Returning patients to their usual activities following reverse total shoulder arthroplasty (RSA) is a critical component of achieving high patient satisfaction. As indications for RSA expand, patients’ desired and achieved activities remains inadequately characterized. We hypothesized that the vast majority of patients undergoing RSA returned to performing desired functional and recreational activities by two years postoperatively, with relatively lower rates of performing activities that involve internal rotation.

Methods

A shoulder arthroplasty registry at a tertiary care orthopedic hospital was reviewed retrospectively to identify specific patient activity capabilities at a minimum of two years postoperatively. Individual items within the American Shoulder and Elbow Surgeons (ASES) Shoulder Score and Shoulder Activity Scale (SAS) pertaining to activity levels were reviewed, including free text responses regarding usual work and usual sporting activity.

Results

The study cohort consisted of 238 patients (mean age = 71 ± 8 years, 61% female). Surgical indications consisted of osteoarthritis (69%, n = 164), and rotator cuff arthropathy (31%, n = 74). Median two-year postoperative ASES score for the operative extremity was 85 ± 18. Patients identified household chores (50%, n = 123), desk-related work (16%, n = 39), and heavy lifting activities (3%, n = 7) as the most common forms of usual work. Among 157 patients participating in sports at two years postoperatively, walking (27%, n = 42), golf (23%, n = 36), swimming (19%, n = 30), and weightlifting (15%, n = 24) were the most common sporting activities. At two-year follow-up, a high proportion of patients were able to comb their hair (90%, n = 215), manage toileting (89%, n = 213), and put on a coat (92%, n = 219). A relatively lower proportion of patients reported being able to lift ten pounds overhead (63%, n = 150) or wash their back (59%, n = 140).

Conclusion

Following RSA, patients exhibit a variety of desired functional and recreational activities. There persists a wide spectrum in patients’ capabilities to perform activities at two years postoperatively. The study findings may provide data to guide preoperative patient counseling.

Abstract

Background

Temporal variations during the pitch have demonstrated significant impacts on the kinetic chain, and as such, have implications in injury risk.

Purpose

To determine the effect of varying chronological orders of maximum joint and segment velocities on ball velocity and upper extremity kinetics.

Methods

Professional baseball pitchers (n = 287) were assessed with 3D-motion capture (480 Hz) while pitching. Pitches were categorized into one of the following groups dependent on the first maximum joint or segment velocity achieved out of chronological order in an inferior to superior direction: knee extension (DscK), pelvis rotation (DscP), trunk rotation (DscT), shoulder rotation (DscS), forearm pronation (DscF), and Proper (for pitchers with the correct temporal sequence), and Total Population, for all pitchers. Ten normalized throwing arm kinetic variables were compared among groups. Regression analysis was conducted on the timing of maximum velocities with ball velocity.

Results

The majority of pitches were in the DscK group (64.5%). The DscK group had a significantly slower maximum lead knee extension velocity compared with the Proper group (253°/s vs. 316°/s, P = .017). The Proper group had a significantly faster ball velocity compared with the Total Population (39.0 ± 1.9 m/s vs. 38.3 ± 2.1 m/s, P = .013). The DscP group had a significantly slower maximum pelvis rotation velocity compared with the Proper group (596°/s vs. 698°/s, P < .001). The Proper group had no significant difference in kinetics relative to the population. For every 1 standard deviation delay in attaining maximum lead knee extension velocity, ball velocity increased by 0.38 m/s (B = 3.5, β = 0.18, P < .001). For every 1 standard deviation delay in timing to achieve maximum pelvis rotation velocity, maximum pelvis rotation velocity and ball velocity increased by 22.5°/s (B = 1107.0, β = 0.23, P < .001) and 0.48 m/s (B = 23.4, β = 0.23, P < .001), respectively.

Conclusion

Pitchers with a discordant sequence of knee extension and pelvis rotation velocity timing had significantly slower corresponding segment/joint velocities. Conversely, pitchers with a proper sequence had the fastest ball velocity with minimal differences in throwing arm kinetics. To maximize ball velocity, professional pitchers should consider achieving maximal velocities in an inferior to superior chronological sequence, with a particular focus on the knee and pelvis.

Abstract

Background

The Patient-Reported Outcome Measurement Information System Upper Extremity (PROMIS UE) questionnaire has been validated as an effective and efficient outcome measure after rotator cuff repair (RCR). However, definitions of clinically significant outcomes used in interpreting this outcome measure have yet to be defined.

Purpose

To define clinically significant outcomes of the PROMIS UE questionnaire in patients undergoing arthroscopic RCR.

Study design

Cohort study (diagnosis); Level of evidence, 3.

Methods

We reviewed charts of consecutive patients undergoing RCR in our institution between 2017 and 2018 and included patients who were administered the PROMIS UE before surgery and 12 months after surgery. At 12 months postoperatively, patients were asked domain-specific anchor questions regarding their function and satisfaction after surgery, which were then used to determine the minimal clinically important difference (MCID), Patient Acceptable Symptomatic State (PASS), and substantial clinical benefit (SCB) using receiver operating characteristic and area under the curve (AUC) analysis. Univariate and multivariate logistic regression analysis was utilized to identify patient factors associated with clinically significant outcomes.

Results

A total of 105 patients with RCR and minimum 12-month postoperative PROMIS UE were included in the analysis. The defined clinically significant outcomes were 4.87 for the MCID using a distribution-based method, 7.95 for the SCB (sensitivity, 0.708; specificity, 0.833; AUC, 0.760), and 39.00 for the PASS (sensitivity, 0.789; specificity, 0.720; AUC, 0.815). Among respondents, 79.0%, 62.9%, and 64.8% achieved the MCID, SCB, and PASS score thresholds, respectively. Workers' compensation was negatively associated with achievement of the PASS. Lower preoperative PROMIS UE scores were associated with obtaining the MCID (odds ratio [OR], 0.871; P = .001) and the SCB (OR, 0.900; P = .040), whereas higher preoperative scores were predictive of achieving the PASS (OR, 1.111; P = .020).

Conclusion

This study defines the clinically significant outcomes for the PROMIS UE after RCR, of which the majority of patients achieved the MCID, PASS, and SCB at 12 months after surgery. These thresholds should be considered in future study design and interpretation of PROMIS UE in patients with RCR.

Keywords

Journal

Shoulder Elbow. 2020 Oct;12(5):315-329. doi: 10.1177/1758573220945318.

Abstract

Background

The purpose of this study was to evaluate mid- and long-term outcomes following the Latarjet procedure for anterior shoulder instability.

Methods

PubMed, MEDLINE, Embase, and Cochrane libraries were systematically searched, in line with PRISMA guidelines, for studies reporting on outcomes following the Latarjet procedure with minimum five-year follow-up. Outcomes of studies with follow-up between 5 and 10 years were compared to those with minimum follow-up of 10 years.

Results

Fifteen studies reporting on 1052 Latarjet procedures were included. Recurrent instability occurred in 127 patients, with an overall random summary estimates in studies with a minimum five-year follow-up of 0-18% (I2 = 90%) compared to 5-26% (I2 = 59%) for studies with a minimum 10-year follow-up. Overall rates for return to sports, non-instability related complications, and progression of arthritis estimated at 65-100% (I2 = 87%), 0-20% (I2 = 85%), and 8-42% (I2 = 89%) for the minimum five-year follow-up studies and 62-93% (I2 = 86%), 0-9% (I2 = 28%), and 9-71% (I2 = 91%) for the minimum 10-year follow-up studies, respectively. All studies reported good-to-excellent mean PRO scores at final follow-up.

Conclusions

The Latarjet is a safe and effective procedure for patients with shoulder instability. The majority of patients return to sport, though at long-term follow-up, a trend towards an increased incidence of recurrent instability is appreciated, while a significant number may demonstrate arthritis progression.

Orthopedics. 2020 Oct 1;1-5. doi: 10.3928/01477447-20200923-02.

Abstract

Purpose

The purpose of this study was to determine the association between time from the diagnosis of rotator cuff tear to repair and the rate of subsequent revision surgery for re-tear.

Methods

A national insurance database was queried from 2007 to 2016 for patients who underwent arthroscopic rotator cuff repair after a diagnosis of rotator cuff tear with minimum 5-year follow-up. On the basis of time from diagnosis to repair, patients were stratified into an early (<6 weeks), a routine (between 6 weeks and 12 months), or a delayed (>12 months) repair cohort. The rates of subsequent revision rotator cuff repair were compared pairwise between cohorts with Pearson's chi-square tests. Multivariate logistic regression was used to adjust for patient demographics and comorbidity burden.

Results

A total of 2759 patients were included, with 1510 (54.7%) undergoing early repair, 1104 (40.0%) undergoing routine repair, and 145 (5.3%) having delayed repair. The overall revision rate at 5-year follow-up was 9.6%. The revision rate was higher in the delayed group (15.2%) relative to the early (9.9%) and routine (8.3%) groups (P=.048 and P=.007, respectively). On multivariate analysis, delayed repair was associated with increased odds of revision surgery (odds ratio, 1.97; P=.009) compared with routine repair.

Conclusions

Delayed rotator cuff repair beyond 12 months of diagnosis was associated with an increased risk of undergoing subsequent revision rotator cuff repair while controlling for age and comorbidity burden.

Abstract

Background

Patient satisfaction after primary anatomic and reverse total shoulder arthroplasty (TSA) represents an important metric for gauging patient perception of their care and surgical outcome. Although TSA confers improvement in pain and function for most patients, inevitably some will remain unsatisfied postoperatively. The purpose of the present study was to (1) train supervised machine learning (SML) algorithms to predict satisfaction after TSA and (2) develop a clinical tool for individualized assessment of patient-specific risk factors.

Methods

A retrospective review of primary anatomic and reverse TSA patients between January 2014 and February 2018 was performed. A total of 16 demographic, clinical, and patient-reported outcomes were evaluated for predictive value. Five SML algorithms underwent three iterations of 10-fold cross-validation on a training set (80% of cohort). Assessment by discrimination, calibration, Brier score, and decision curve analysis was performed on an independent testing set (remaining 20% of cohort). Global and local model behavior were evaluated with global variable importance plots and local interpretable model-agnostic explanation, respectively.

Results

The study cohort consisted of 413 patients, of which 331 (82.6%) were satisfied at two-years postoperatively. The support vector machine (SVM) model demonstrated the best relative performance on the independent testing set not used for model training (c-statistic=0.80, calibration intercept=0.20, calibration slope=2.32, Brier score=0.11). The most important factors for predicting satisfaction were baseline single assessment numeric evaluation (SANE) score, exercise and activity, workers compensation status, diagnosis, symptom duration prior to surgery, body mass index, age, smoking status, anatomic vs. reverse TSA, and diabetes. The SVM algorithm was incorporated into an open-access digital application for patient-level explanations of risk and predictions available here: https://orthopedics.shinyapps.io/SatisfactionTSA/

Conclusion

The best performing SML model demonstrated excellent discrimination and adequate calibration for predicting satisfaction following TSA and was used to create an open-access, clinical-decision making tool. However, rigorous external validation in different geographic locations and patient populations is essential prior to assessment of clinical utility. Given that this tool is based on partially modifiable risk factors it may enhance shared decision making and allow for periods of targeted, preoperative health optimization efforts.
