Aims. Patient-reported outcome measures have become an important part of routine care. The aim of this study was to determine if Patient-Reported Outcomes Measurement Information System (PROMIS) measures can be used to create patient subgroups for individuals seeking orthopaedic care. Methods. This was a cross-sectional study of patients from Duke University Department of Orthopaedic Surgery clinics (14 ambulatory and four hospital-based). There were two separate cohorts recruited by convenience sampling (i.e. patients were included in the analysis only if they completed PROMIS measures during a new patient visit). Cohort #1 (n = 12,141; December 2017 to December 2018,) included PROMIS short forms for eight domains (Physical Function, Pain Interference, Pain Intensity, Depression, Anxiety, Sleep Quality, Participation in Social Roles, and Fatigue) and Cohort #2 (n = 4,638; January 2019 to August 2019) included PROMIS Computer Adaptive Testing instruments for four domains (Physical Function, Pain Interference, Depression, and Sleep Quality). Cluster analysis (K-means method) empirically derived subgroups and subgroup differences in clinical and sociodemographic factors were identified with one-way analysis of variance. Results. Cluster analysis yielded four subgroups with similar clinical characteristics in Cohort #1 and #2. The subgroups were: 1) Normal Function: within normal limits in Physical Function, Pain Interference, Depression, and Sleep Quality; 2) Mild Impairment: mild deficits in Physical Function, Pain Interference, and Sleep Quality but with Depression within normal limits; 3) Impaired Function, Not Distressed: moderate deficits in Physical Function and Pain Interference, but within normal limits for Depression and Sleep Quality; and 4) Impaired Function, Distressed: moderate (Physical Function, Pain Interference, and Sleep Quality) and mild (Depression) deficits. Conclusion. These findings suggest orthopaedic patient subgroups differing in physical function, pain, and psychosocial distress can be created from as few as four different PROMIS measures. Longitudinal research is necessary to determine whether these subgroups have prognostic validity. Cite this article: Bone Jt Open 2021;2(7):493–502

A major cause of morbidity in lower limb amputees is phantom limb pain (PLP) and residual limb pain (RLP). This study aimed to determine if surgical interposition of nerve endings into adjacent muscle bellies at the time of major lower limb amputation can decrease the incidence and severity of PLP and RLP. Data was retrospectively collected from January 2015 to January 2021, including eight patients that underwent nerve interposition (NI) and 36 that received standard treatment. Primary outcomes included the 11-point Numerical Rating Scale (NRS) for pain severity, and Patient-Reported Outcomes Measurement Information System (PROMIS) pain intensity, behaviour, and interference. Secondary outcome included Neuro-QoL Lower Extremity Function assessing mobility. Cumulative scores were transformed to standardised t scores. Across all primary and secondary outcomes, NI patients had lower PLP and RLP. Mean ‘worst pain’ score was 3.5 out of 10 for PLP in the NI cohort, compared to 4.89 in the control cohort (p=0.298), and 2.6 out of 10 for RLP in the NI cohort, compared to 4.44 in the control cohort (p=0.035). Mean ‘best pain’ and ‘current pain’ scores were also superior in the NI cohort for PLP (p=0.003, p=0.022), and RLP (p=0.018, p=0.134). Mean PROMIS t scores were lower for the NI cohort for RLP (40.1 vs 49.4 for pain intensity; p=0.014, 44.4 vs 48.2 for pain interference; p=0.085, 42.5 vs 49.9 for pain behaviour; p=0.025). Mean PROMIS t scores were also lower for the NI cohort for PLP (42.5 vs 52.7 for pain intensity; p=0.018); 45.0 vs 51.5 for pain interference; p=0.015, 46.3 vs 51.1 for pain behaviour; p=0.569). Mean Neuro-QoL t score was lower in NI cohort (45.4 vs 41.9;p=0.03). Surgical interposition of nerve endings during lower limb amputation is a simple yet effective way of minimising PLP and RLP, improving patients’ subsequent quality of life. Additional comparisons with targeted muscle reinnervation should be performed to determine the optimal treatment option

Persistent post-surgical pain and associated disability are common after a traumatic fracture repair. Preliminary evidence suggests that patients' beliefs and perceptions may influence their prognosis. We sought to explore this association. We used data from the Fluid Lavage of Open Wounds trial to determine, in 1560 open fracture patients undergoing surgical repair, the association between Somatic PreOccupation and Coping (captured by the SPOC questionnaire) and recovery at 1 year. Of the 1218 open fracture patients with complete data available for analysis, 813 (66.7%) reported moderate to extreme pain at 1 yr. The addition of SPOC scores to an adjusted regression model to predict persistent pain improved the concordance statistic from 0.66 to 0.74, and found the greatest risk was associated with high SPOC scores [odds ratio: 5.63, 99% confidence interval (CI): 3.59–8.84, absolute risk increase 40.6%, 99% CI: 30.8%, 48.6%]. Thirty-eight per cent (484 of 1277) reported moderate to extreme pain interference at 1 yr. The addition of SPOC scores to an adjusted regression model to predict pain interference improved the concordance statistic from 0.66 to 0.75, and the greatest risk was associated with high SPOC scores (odds ratio: 6.06, 99% CI: 3.97–9.25, absolute risk increase: 18.3%, 95% CI: 11.7%, 26.7%). In our adjusted multivariable regression models, SPOC scores at 6 weeks post-surgery accounted for 10% of the variation in short form-12 physical component summary scores and 14% of short form-12 mental component summary scores at 1 yr. Amongst patients undergoing surgical repair of open extremity fractures, high SPOC questionnaire scores at 6 weeks post-surgery were predictive of persistent pain, reduced quality of life, and pain interference at 1 yr

This study evaluates patient reported outcome measurement information system (PROMIS) scores after total hip arthroplasty (THA) and total ankle arthroplasty (TAA) in matched cohorts, while simultaneously evaluating implant survivorship and 90-day hospital utilization. It is hypothesized that while both procedures would yield similar PROMIS score improvements, THA would demonstrate superior mid-term implant survivorship. Primary THA and TAA patients from 2015–2022 with minimum one-year follow-up were retrospectively reviewed. After applying exclusion criteria, 2,092 THAs and 478 TAAs were included for analysis. Demographics, pre- and post-operative patient reported outcome measures (PROMs), revision surgeries, ED visits, and re-admissions were collected. THA and TAA patients were then propensity score matched at 2:1 ratio for age, sex, race, BMI, ASA, and comorbidities, resulting in a final cohort of 844 THAs and 455 TAAs for comparison. There were similar pre-operative PROMIS Pain Interference (PI) scores between THA and TAA, with both showing improvement at six weeks. However, THA patients exhibited lower PI scores at one year (53.0 versus 54.0; p=0.009). Pre-operative PROMIS Physical Function (PF) was worse in THA patients but showed greater improvement compared to TAA patients at both six weeks (p<0.001) and one year (p<0.001). Pre-operative PROMIS depression scores were similar and improved similarly in both groups. Joint-specific PROMs (HOOS for THA and FAAM for TAA) improved in both cohorts. THA demonstrated superior survivorship free of all-cause revision at five years compared to TAA (95% versus 77%; p<0.0001). Patients undergoing THA or TAA experienced significant improvements in their general and joint-specific PROMs post-operatively. However, patients undergoing THA demonstrated higher PROMIS PI and PF scores at one-year when compared to TAA, as well as improved survivorship. Generic PRO instruments enable comparison of medical treatments in different anatomic sites to the patients overall health

In light of recent regulatory initiatives, medical devices now require additional clinical evidence to prove their safety and efficacy. At the same time, patients' own assessment of their devices' function and performance has gained in importance. The collection of these data allows for a more comprehensive picture of clinical outcomes and complications following total knee arthroplasty (TKA). These trends have led researchers to search for new methods of acquiring, interpreting and disseminating patient-reported outcome measurements (PROMs). The current study assesses the feasibility of a digital platform for collecting PROMs that was recently adapted for TKA patients. It sought to determine patient engagement, survey completion rates, and satisfaction with this platform. Eighty-two patients (mean age, 63.7 years, 59% females) scheduled for TKA were enrolled from one US and six UK sites between January 12, 2018 and April 30, 2018. Patients were supplied with a mobile application (app) that collects a variety of PROMs, including four domains based on the Patient-Reported Outcome Information System (PROMIS™): physical function, depression, pain interference and pain behavior. The platform electronically administers questionnaires using computer-adaptive tests (CATs), which reduce the burden on patients by tailoring follow-up questions to account for their previous answers. Satisfaction with the app was assessed in subset of patients who evaluated its ease-of-use (n=45), likelihood that they would recommend it to family/friends (n=35), and whether they successfully used the information it provided during their recovery (n=31). These scores were taken on a 1 to 10 (worst to best) scale. Patients demonstrated regular engagement with the platform, with 73% using the app at least once a week. Weekly engagement remained high throughout the seven-week post-operative period (Figure 1). There was a 69% completion rate of all PROMIS™ CAT surveys during the study. The four PROMIS™ CAT domains had similar survey completion rates (Figure 2). The subset of patients queried regarding their satisfaction with the app gave it favorable mean scores for ease-of-use (8.8), likelihood to recommend to a family member or friend (8.1), and their success at using its information to improve their recovery (7.4). Initial results support this digital platform's potential for successfully and efficiently collecting large volumes of PROMs. Patients reported high levels of engagement and satisfaction.

Introduction. Direct anterior approach (DAA) total hip arthroplasty (THA) has been reported to improve early outcomes as compared to posterior approach THA up to 6 weeks post-operatively. However, very few detailed results have been reported within the first 6 weeks. In this study we investigate the effect of surgical approach on THA outcome via weekly assessment. Methods. Patients undergoing THA for primary osteoarthritis were prospectively enrolled. Data was collected pre-operatively and post-operatively at weekly intervals for 6 weeks. Outcome scores and additional functional measures were compared using unpaired t-test, effect size, and Pearson correlation coefficients. Results. 111 patients (55 DAA and 56 posterior approach) were enrolled. There was no significant difference (p>0.05) in pre-surgical Patient Reported Outcome Measurement Information System (PROMIS) Pain interference and Physical Function scores, VAS Pain, and Modified Harris Hip Scores (mHHS). Post-operatively, the DAA group had decreased length of stay [1.4 vs 2.2 days, p=0.0002] and increased distance walked on postoperative day 1 and 2 [95 vs 52 ft, p=0.011 and 251 vs. 163 ft, p=0.0004, respectively]. The DAA group had lower VAS pain scores [p<0.05] and required less day 1 and total narcotics [59 vs 80 morphine equivalents, p=0.029 and 138 vs 190, p=0.01, respectively]. The DAA cohort had improved PROMIS Physical Function scores and mHHS up to 5 weeks post- operatively. Anterior approach patients discontinued their assistive device 8 days earlier [p=0.01], left home 3 days earlier [p=0.001], and drove a car 5 days earlier [p=0.016] compared to posterior patients. Conclusion. Patients undergoing DAA THA had significantly shorter length of stay, improved mobilization, decreased narcotic requirements and improved inpatient VAS pain scores compared to mini-posterior THA. Furthermore, DAA patients discontinued their assistive device, left their home, and drove a car sooner than posterior approach patients. The significant improvement in physical function seen with DAA THA persisted up to 5 weeks post-operatively

Aims

The primary aim of this study was to assess the feasibility of recruiting and retaining patients to a patient-blinded randomized controlled trial comparing corticosteroid injection (CSI) to autologous protein solution (APS) injection for the treatment of subacromial shoulder pain in a community care setting. The study focused on recruitment rates and retention of participants throughout, and collected data on the interventions’ safety and efficacy.

Aims

Lower limb reconstruction (LLR) has a profound impact on patients, affecting multiple areas of their lives. Many patient-reported outcome measures (PROMs) are employed to assess these impacts; however, there are concerns that they do not adequately capture all outcomes important to patients, and may lack content validity in this context. This review explored whether PROMs used with adults requiring, undergoing, or after undergoing LLR exhibited content validity and adequately captured outcomes considered relevant and important to patients.

Aims

Fractures of the humeral shaft represent 3% to 5% of all fractures. The most common treatment for isolated humeral diaphysis fractures in the UK is non-operative using functional bracing, which carries a low risk of complications, but is associated with a longer healing time and a greater risk of nonunion than surgery. There is an increasing trend to surgical treatment, which may lead to quicker functional recovery and lower rates of fracture nonunion than functional bracing. However, surgery carries inherent risk, including infection, bleeding, and nerve damage. The aim of this trial is to evaluate the clinical and cost-effectiveness of functional bracing compared to surgical fixation for the treatment of humeral shaft fractures.

Aims

Better prediction of outcome after total hip arthroplasty (THA) is warranted. Systemic inflammation and central neuroinflammation are possibly involved in progression of osteoarthritis and pain. We explored whether inflammatory biomarkers in blood and cerebrospinal fluid (CSF) were associated with clinical outcome, and baseline pain or disability, 12 months after THA.

Introduction. Past research has focused on complications of bony fixation of navigation reference frames such as fractures and cutting errors. Objective. This study investigates the consequences of the use of iliac crest percutaneous navigational array pins in terms of pain, irritability and the impact on quality of life. Method. A prospective, consecutive series of 30 patients presenting for navigated total hip arthroplasty were included in the study. In all patients two temporary 125 × 4 mm Schanz screws were inserted into the iliac crest for the attachment of a navigational reference array. Patients were followed up by telephone at six weeks and three months post-operatively. Patients were also questioned regarding pain, interference with daily activities, pain or discomfort with clothing, how often the wound was noticed and how much time passed before the pain from the site went away completely. Results. All patients had a pre-operative pain score of 0 for the iliac crest region. Overall, a total of 17 patients (57%) reported pain from the pin-site at least once in the post-operative period. In these patients who reported pain, it lasted a mean of 30 ± 31 days (range, 4 to 122 days). The proportion of patients describing pain from the puncture site decreased steadily during the post-operative period from 30% at 3 weeks to 10% at 6 weeks and 4% (1 patient) at 3 months. A total of 9 patients (30%) described discomfort or pain at the pin-site irritated by wearing close-fitting clothing or a belt. The wound was not noticed at all by the majority of patients (80%) by 3-months post-operatively. Conclusion. The use of navigational pins for array fixation often causes pain and irritability for the patient, however this largely resolves in the short-term. This study suggests the incision for pin insertion be made more posteriorly along the iliac crest to reduce the likelihood of irritation with clothing

Aims

The increase in prescription opioid misuse and dependence is now a public health crisis in the UK. It is recognized as a whole-person problem that involves both the medical and the psychosocial needs of patients. Analyzing aspects of pathophysiology, emotional health, and social wellbeing associated with persistent opioid use after injury may inform safe and effective alleviation of pain while minimizing risk of misuse or dependence. Our objectives were to investigate patient factors associated with opioid use two to four weeks and six to nine months after an upper limb fracture.
