Background

Hip arthroscopy is commonly performed to treat various hip conditions, but some patients may require a total hip arthroplasty (THA) afterward. This study aimed to validate a previously published risk score to predict which hip arthroscopy patients are most likely to require conversion to THA.

Methods

The study analyzed patients who underwent hip arthroscopy between November 2015 and March 2017. They were followed for at least 2 years to see if they needed a THA. The risk score, which factors in age, hip scores, and other factors, was validated using these patients' data.

Key Findings

Out of 187 patients, 13 (7%) needed a THA within an average of 1.6 years. The risk score accurately predicted which patients were at high risk for conversion, showing high accuracy with a receiver operating characteristic (ROC) curve of 0.894 (excellent prediction capability).

Conclusions

The risk score can help predict which hip arthroscopy patients might need a THA in the future. This tool provides valuable information for surgeons to better counsel patients and guide treatment decisions.

What Does This Mean for Patients

If you’re considering hip arthroscopy, your doctor can use this risk score to help predict whether you might need a hip replacement down the line, improving the planning and expectations for your treatment.
