Hip Surgical Treatment Registry (HipSTR): The North American Hip Arthroscopy Registry—Who We Are Operating on and What We Are Doing;Findings in Its Inaugural Year 2023 With >1000 Patients

Abstract

Background:

In 2023, the first North American Hip Arthroscopy Registry was released: the Hip Surgical Treatment Registry (HipSTR). HipSTR is a prospective web-based data collection registry designed to gather baseline patient information, procedural data, and surgical outcomes.

Purpose:

To present the initial demographic and surgical overview data for patients enrolled in 2023.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Beta testing of HipSTR occurred between February 2023 and July 23, 2023, by 7 surgeons on >400 patients. Starting July 23, 2023, HipSTR was made available for enrollment by North American orthopaedic surgeons. HipSTR is a free, digitally administered registry integrated with cloud-based (Patient IQ) outcome database capturing preoperative demographics, patient-reported outcome (PRO) measures, and intraoperative surgical data.

Results:

As of December 31, 2023, 14 surgical sites with 21 participating surgeons were enrolling hip arthroscopy patients, totaling 1098 patients in the calendar year 2023. The registry included 65% female patients and 34% male patients, with a mean age of 36.6 ± 14 years. Baseline compliance was 90%. Mean preoperative PRO measures (the 12-item International Hip Outcome Tool, EuroQol 5 Dimension 5 Level Visual Analog Scale, and Hip Single Assessment Numeric Evaluation scores) were 39.7 ± 19.0, 69.6 ± 19.6 and 39.1 ± 21.7, respectively, indicating the significant impact of their hip pain. In total, 315 patients described themselves as an athlete. Surgical findings revealed a variety of hip pathology, including 45% CAM lesions, 43% labral tears, 38% acetabular chondral lesions, 26% pincer morphology. Among patients with CAM and pincer/anterior inferior iliac spine morphology, 98% and 75% underwent femoral osteoplasty and acetabuloplasty, respectively. Additionally, 56% of all patients with acetabular cartilage injury underwent acetabular chondroplasty and 9% underwent microfracture. Notably, 16% of patients had prior surgery on their affected hip. Formal capsulotomies were performed in 68.3% of patients and of these, 83% had their capsulotomy fully repaired.

Conclusion:

These findings provide initial insights into the demographics and clinical profiles of North American patients undergoing hip arthroscopy as well as the types of procedures performed. These data, along with future contributions as the registry expands, will enhance understanding of the pathologies managed with hip arthroscopy, evaluate PRO measures to assess procedural efficacy, and guide efforts in the prevention and management of hip pain.
