PROMIS Utilization in Pediatric Orthopaedics: A Scoping Review

BACKGROUND

The lack of a common patient-reported outcome metric used among the orthopaedic population is a problem that has been previously identified by the American Academy of Orthopaedic Surgeons. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed by the National Institute of Health with the goal of creating a precise and efficient measurement tool for patient-reported symptoms, functioning, and health-related quality of life to be used in clinical research. A study summarizing its use in the pediatric orthopaedic population has not been previously performed.

METHODS

We performed a literature search of Ovid Medline, Embase, Scopus, and the Cochrane Central Register of Controlled Trials from 2010 to August 2021. There were 1961 unique citations included after the removal of 1756 duplicates. After initial screening, 183 studies were screened under full-text review leaving a final number of 51 studies included in this scoping review.

RESULTS

Pediatric PROMIS studies were grouped by body part or sub-speciality: "Hand and Upper Extremity" (25.5%, n=13), "Sports" (23.5%, n=12), "Spine" (13.7%, n=7), "Trauma" (13.7%, n=7), "General Pediatric Orthopaedics" (11.8%, n=6), "Lower Extremity" (9.8%, n=5), and "Orthopaedic Oncology" (2%, n=1). An increase in studies utilizing PROMIS was seen throughout the study period with only 3 studies published from 2013 to 2016 to 39 in 2020 and 2021 alone. The 3 most frequently used pediatric PROMIS domains were Pain Interference (76.5%, n=39/51), Mobility (60.8%, n=31/51), and Upper Extremity (54.9%, n=28/51). 64.3% (n=9/14) of the included studies which reported on the floor effects of Pain Interference exhibited a significant floor effect. In all, 77.8% (n=7/9) of the included studies which reported on ceiling effects of Upper Extremity exhibited a significant ceiling effect.

CONCLUSION

The use of PROMIS increased significantly since the first publication in 2013 suggesting orthopaedic providers have increasingly utilized PROMIS in their day-to-day practice as an outcome measure. Ceiling and floor effects were prominent in several of the included domains (Pain Interference and Upper Extremity). Overall, PROMIS measures are efficient, reliable, and effective to use.

Meniscal Repair Outcomes at Greater Than 5 Years: A Systematic Review and Meta-Analysis

BACKGROUND

The utilization of meniscal repair techniques continues to evolve in an effort to maximize the rate of healing. Meniscal repair outcomes at a minimum of 5 years postoperatively appear to better represent the true failure rates. Thus, a systematic review and meta-analysis of the current literature was conducted to assess the rate of failure at a minimum of 5 years after meniscal repair.

METHODS

We performed a systematic review of studies reporting the outcomes of meniscal repair at a minimum of 5 years postoperatively. A standardized search and review strategy was utilized. Failure was defined as recurrent clinical symptoms or a meniscal reintervention to repair or resect the meniscus in any capacity, as defined by the study. When reported, outcomes were assessed relative to anterior cruciate ligament (ACL) status, sex, age, and postoperative rehabilitation protocol. Meta-analyses were performed with a random-effects model.

RESULTS

A total of 27 studies of 1,612 patients and 1,630 meniscal repairs were included in this review and meta-analysis. The pooled overall failure rate was 22.6%, while the failure rate of modern repairs (excluding early-generation all-inside devices) was 19.5%. Medial repairs were significantly more likely to fail compared with lateral repairs (23.9% versus 12.6%, p = 0.04). Failure rates were similar for inside-out (14.2%) and modern all-inside repairs (15.8%). Early-generation all-inside devices had a significantly higher failure rate (30.2%) compared with modern all-inside devices (15.8%, p = 0.01). There was no significant difference in meniscal failure rate between repairs with concomitant ACL reconstruction (21.2%) and repairs in ACL-intact knees (23.3%, p = 0.54).

CONCLUSIONS

Modern meniscal repair had an overall failure rate of 19.5% at a minimum of 5 years postoperatively. Modern all-inside techniques appear to have improved the success rate of meniscal repair compared with use of early-generation all-inside devices. Lateral repairs were significantly more likely to be successful compared with medial repairs, while no difference was seen between patients undergoing meniscal repair with and without concomitant ACL reconstruction.

Treatment Trends in Meniscal Pathology in the Setting of Concomitant ACL Injuries in Pediatric and Young Adult Patients: An Insurance Database Study

BACKGROUND

Meniscal pathology is commonly encountered in the setting of anterior cruciate ligament (ACL) rupture and is increasingly common in the pediatric and adolescent population. Studies have shown that over half of individuals presenting with ACL rupture will have concurrent meniscal pathology.

PURPOSE

To define trends in the utilization of meniscal procedures (ie, meniscus repair vs partial meniscectomy) and short-term complications in pediatric and young adult patients with meniscal pathology in the setting of a concurrent ACL reconstruction.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

The IBM MarketScan Commercial Database was utilized to identify ACL reconstruction procedures performed between 2006 and 2018 for individuals aged 5 to 30 years. Annual proportions of meniscectomy and meniscal repair were analyzed, and short-term complications were compared between pediatric/adolescent patients (aged 5-17 years) and young adults (aged 18-30 years).

RESULTS

An overall 40,736 records of individuals <18 years old with ACL tears were included. The pediatric/adolescent population had a significantly lower proportion of concomitant meniscal procedures (56.8%; 23,149/40,736) than the young adult population (59.7%; 33,764/56,515; P < .01). From 2006 to 2018, utilization of meniscal repair in the setting of ACL reconstruction steadily increased (20.1% to 35.1% [+15 percentage points], P < .01), while the proportion with meniscectomy decreased (34.4% to 21.3% [-13.1 percentage points], P < .01). There was no difference in rate of reoperation for repeat meniscal repair or meniscectomy in the pediatric/adolescent population for those undergoing meniscal repair versus meniscectomy within 180 days of primary surgery (1.7% [188/10,766] vs 1.5% [186/12,383]; P = .14).

CONCLUSION

From 2006 to 2018, the proportion of patients receiving ACL reconstruction with concomitant meniscal repair increased (20.1% to 35.1%) while the proportion with meniscectomy decreased (34.4% to 21.3%) in the pediatric/adolescent population. Meniscal repair was not associated with a higher 180-day rate of reoperation for repeat meniscal repair or meniscectomy than meniscectomy in the setting of ACL reconstruction.

Rates of Infection After ACL Reconstruction in Pediatric and Adolescent Patients: A MarketScan Database Study of 44,501 Patients

BACKGROUND

Numerous studies have demonstrated an increase in the number of anterior cruciate ligament (ACL) reconstruction procedures performed in pediatric patients. Despite this, most knowledge of surgical site infection rates after these procedures are based on adult studies and data is currently limited in pediatric patients. The purpose of this study was to describe and analyze the rates of infection after ACL reconstruction among pediatric patients and adolescent patients (compared with young adult patients) utilizing the MarketScan Commercial Claims and Encounters Database.

METHODS

The Truven Health Analytics MarketScan Commercial Claims and Encounters database was assessed to access health care utilization data for privately insured individuals aged 5 to 30 years old. ACL reconstruction records performed between 2006 and 2018 were identified using Current Procedures Terminology (CPT) codes. International Classification of Diseases Ninth Revision (ICD-9), Tenth (ICD-10) codes and CPT codes were used to identify patients requiring treatment for infection. All patients had at least 180 days of insurance coverage after intervention.

RESULTS

A total of 44,501 individuals aged below 18 years old and 63,495 individuals aged 18 to 30 years old that underwent arthroscopic ACL reconstruction were identified. There were no differences in infection rates between those below 18 years old (0.52%) and those above 18 years old (0.46%, P=0.227). However, among patients below 18 years old, patients below 15 years old had a significantly lower rate of infection at 0.37% compared with adolescents (15 to 17 y old) at 0.55% (P=0.039). Among young adults, males had higher rates of infection than females (0.52% vs. 0.37%), while no difference was observed in the pediatric and adolescent population (0.58% vs. 0.47%, P=0.109).

CONCLUSION

Utilizing an insurance database, this study demonstrated that rates of infection after ACL Reconstruction in a pediatric/adolescent population are low (0.52%) and similar to rates in young adults. Infection rates after ACLR reconstruction appear to be slightly lower in patients under 15 years of age (0.37%).

Quadrilateral space region inflammation and other incidental findings on shoulder MRI following recent COVID-19 vaccination: Three case reports

We present 3 cases reporting the normal appearance of the post COVID-19 vaccination on shoulder MRI exams. All 3 patients were imaged 1 to 5 days post-vaccination for unrelated MSK shoulder symptoms, and none reported any symptoms besides mild shoulder discomfort for a day or 2 following vaccine administration. All 3 patients demonstrated characteristic deltoid edema, quadrilateral space region edema and axillary nodal prominence. Vessel prominence with t2 and t1 increased signal draining to the approximate location of the quadrilateral space and axilla was an associated feature. The normal appearance of the covid-19 vaccine on shoulder MRI has not been previously described, and recognition by the radiologist will prevent erroneous differential diagnosis, unnecessary medical workups, and detract from the clinically relevant pathological imaging findings in patients with shoulder pain.

The Drosophila suppressor of sable gene encodes a polypeptide with regions similar to those of RNA-binding proteins

The nucleotide sequence of the Drosophila melanogaster suppressor of sable [su(s)] gene has been determined. Comparison of genomic and cDNA sequences indicates that an approximately 7,860-nucleotide primary transcript is processed into an approximately 5-kb message, expressed during all stages of the life cycle, that contains an open reading frame capable of encoding a 1,322-amino-acid protein of approximately 150 kDa. The putative protein contains an RNA recognition motif-like region and a highly charged arginine-, lysine-, serine-, aspartic or glutamic acid-rich region that is similar to a region contained in several RNA-processing proteins. In vitro translation of in vitro-transcribed RNA from a complete cDNA yields a product whose size agrees with the size predicted by the open reading frame. Antisera against su(s) fusion proteins recognize the in vitro-translated protein and detect a protein of identical size in the nuclear fractions from tissue culture cells and embryos. The protein is also present in smaller amounts in cytoplasmic fractions of embryos. That the su(s) protein has regions similar in structure to RNA-processing protein is consistent with its known role in affecting the transcript levels of those alleles that it suppresses.

Molecular analysis of chemically-induced mutations at the RpII215 locus of Drosophila melanogaster

A substantial fraction, perhaps 50% or more, of spontaneous mutations in Drosophila melanogaster have been shown by molecular analyses to be associated with the presence of a transposable element (TE) inserted into the affected gene. We are interested in the molecular structure of induced mutations in Drosophila, in particular whether TEs are also responsible for a significant proportion of chemically-induced mutations. We report here the molecular analysis of 58 mutations at the RpII215 locus induced with EMS or ENU. While we find evidence for moderately sized deletions at this locus (in 3/58, or 5% of the examined mutants), we failed to detect any mutations which were associated with an insertion event. It may be the case that induced mutations are qualitatively different from spontaneous mutations.
