Experience and outcome data of the British non-arthroplasty hip registry

Evaluating the Use of PROMs in Paediatric Orthopaedic Registries

Patient-reported outcome measures (PROMs) provide structured information on the patient's health experience and facilitate shared clinical decision-making. Registries that collect PROMs generate essential information about the clinical course and efficacy of interventions. Whilst PROMs are increasingly being used in adult orthopaedic registries, their use in paediatric orthopaedic registries is not well known. The purpose of this systematic review was to identify the frequency and scope of registries that collect PROMs in paediatric orthopaedic patient groups. In July 2023, six databases were systematically searched to identify studies that collected PROMs using a registry amongst patients aged under 18 years with orthopaedic diagnoses. Of 3190 identified articles, 128 unique registries were identified. Three were exclusively paediatric, 27 were majority paediatric, and the remainder included a minority of paediatric patients. One hundred and twenty-eight registries collected 72 different PROMs, and 58% of these PROMs were not validated for a paediatric population. The largest group of orthopaedic registries collected PROMs on knee ligament injuries (21%). There are few reported dedicated orthopaedic registries collecting PROMs in paediatric populations. The majority of PROMs collected amongst paediatric populations by orthopaedic registries are not validated for patients under the age of 18 years. The use of non-validated PROMs by registries greatly impedes their utility and impact. Dedicated orthopaedic registries collecting paediatric-validated PROMs are needed to increase health knowledge, improve decision-making between patients and healthcare providers, and optimise orthopaedic management.

Evaluation of outcome reporting trends for femoroacetabular impingement syndrome- a systematic review

PURPOSE

The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included.

METHODS

This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18 years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs.

RESULTS

The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004-2008)-(2016-2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0 months (± 17 SD), (range 1.5-120 months). Between 1-10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%).

CONCLUSION

There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM.

An Updated Description of More Than 5,000 Procedures from the Danish Hip Arthroscopy Registry

BACKGROUND

The Danish Hip Arthroscopy Registry (DHAR) started as a web-based prospective registry in 2012. The aim of this study was to evaluate and report epidemiologic and perioperative data from 5,333 procedures and to describe the development of the DHAR.

METHODS

The DHAR collects data from patients prospectively at the time of inclusion (preoperative evaluation) and at 1, 2, 5, and 10 years after arthroscopic hip surgery. The surgeon reports surgical data at the time of surgery. The DHAR uses a number of validated patient-related outcome measures (PROMs): the Copenhagen Hip and Groin Outcome Score (HAGOS), Hip Sports Activity Scale (HSAS), EuroQol 5 Dimensions (EQ-5D), and a numeric rating scale for pain (NRS pain).

RESULTS

Of the 5,333 procedures, 58% were done in female patients. The mean age was 37.7 years. The mean duration of surgery was 78 minutes, and the mean duration of traction was 45 minutes. Combined cam and pincer resections were performed in 64% of the patients, and labral repair was done in 82%. The most common type of acetabular chondral damage found was Beck grade-2 lesions (43%). Grade-3 and 4 changes were seen in 29% and 11% of the patients, respectively. The 1-year HAGOS PROM values increased to a median of 69.1 (interquartile range [IQR], 68.2 to 70.0) for pain, 64.9 (IQR, 64.0 to 65.7) for symptoms, 71.3 (IQR, 70.3 to 72.3) for activities of daily living, 56.2 (IQR, 55.1 to 57.4) for sports, 42.2 (IQR, 40.8 to 43.5) for physical activity, and 50.7 (IQR, 49.7 to 51.8) for quality of life, and the 1-year EQ-5D increased to a median of 0.75 (IQR, 0.74 to 0.76). Five-year outcomes for 383 patients showed a significant increase in all PROMs (p < 0.05).

CONCLUSIONS

Patients referred for hip arthroscopy reported pain, functional disabilities, and a decreased activity level and quality of life prior to surgery but demonstrated improvements after 1 and 5 years. The problems with developing and maintaining a large clinical registry are described. The development of a national clinical registry for hip arthroscopy was considered successful.

Functional acetabular retroversion syndrome: description of a specific sub-type of FAI and results of treatment with minimally invasive PAO

INTRODUCTION

Acetabular retroversion syndrome is associated with pincer-type femoroacetabular impingement (FAI) and results, theoretically, from an externally rotated hemipelvis. The purpose of this study was to examine our surgical experience and the clinical results of functional acetabular retroversion syndrome treated with minimally-invasive periacetabular osteotomy (PAO).

METHODS

We performed a retrospective cohort study of prospectively collected data in consecutive patients who had an anteverting PAO from 01 November 2010 to 31 December 2015. All patients were followed up clinically and radiologically.Functional scores were ascertained using pre- and postoperative iHOT-12 and EQ-5D. The effect of hypermobility, smoking status and body mass index (BMI) on outcome measures was evaluated.

RESULTS

31 anteverting PAOs were performed on 27 consecutive patients. All patients were female. The mean age was 26.7 years (SD 6.7). The mean BMI was 25.8 kg/m² (SD 5.1). 5 patients were smokers (16.1%) and 11 exhibited signs of generalised joint laxity. 23 hips had undergone prior hip arthroscopy and 1 patient had previous open FAI surgery. The minimum clinical follow-up was 2 years (mean 3.4 years; range 2-7 years). A crossover sign was present in all cases. The mean iHOT-12 score improved from 19.5 to 51 at 6 months, 64.5 at 1 year and 48 at 2 years following surgery (p < 0.05) EQ-5D improved from 0.42 preoperatively to 0.76 at 6 months and 0.69 at 1 year following surgery (p < 0.05).

CONCLUSIONS

We have characterised functional acetabular retroversion syndrome (FARS) as a condition affecting young, active females which severe symptoms out of proportion to demonstrable radiographic pathology.

The Danish Hip Arthroscopy Registry: Registration Completeness and Patient Characteristics Between Responders and Non-Responders

Purpose

To report completeness of registered surgeries in the Danish hip arthroscopy registry (DHAR) and proportion of patients completing patient-reported outcome measures (PROMs) prior to surgery and at 1-year follow-up.

Patients and Methods

Completeness was determined as the number of surgeries registered in DHAR in comparison with the number of surgeries registered in the Danish National Patient Registry database (DNPR). The number of patients self-reporting pre-surgical PROMs was compared to the total number of surgeries registered in DHAR. Further, we evaluated potential differences in baseline characteristics between the groups of responders and non-responders at 1-year follow-up. Patient characteristics included age, sex, activity levels measured by the hip sports activity scale (HSAS), and PROMs (Copenhagen Hip and Groin Outcome Score, EQ-5D-3L and general hip status). Age was stratified in three groups (<25, 25–39, ≥40).

Results

From February 2012 to September 2018, 5565 arthroscopic hip surgeries were registered in DNPR, and 4937 were registered in DHAR (89%). The yearly rate of registrations in DHAR compared to DNPR increased from 77% in 2012 to 85% in 2018 and peaking in 2015 at 94%. A total of 3294 DHAR-registered patients (67%) had self-reported their pre-surgical outcome scores, and of those, 2886 (58%) completed PROMs at 1-year follow-up. More males (45 vs 41%, p = 0.002) and individuals younger than 25 years of age (24% vs 18%, p<0.001) had not completed follow-up questionnaire. The PROM baseline scores of the responders at follow-up did not differ from the non-responders.

Conclusion

The proportion of arthroscopic hip surgeries registered in the Danish Hip Arthroscopy Registry and the proportion of self-reporting PROM scores have increased to acceptable levels, whereas the proportion of patients with follow-up data is comparably low. For further quality improvement, more attention should be given to patients completing PROMs, focusing on younger males and follow-up PROMs.
