Population-based analysis identifies factors of conversion to THA after hip arthroscopy
Investigators of this retrospective, comparative study found older patients and patients who were either obese or had osteoarthritis had higher rates of conversion to total hip arthroplasty within 2 years of hip arthroscopy.
"The take home message is that hip arthroscopy is a very good surgical procedure for the right indications, but does not work well for older patients and patients with degenerative arthritis,” David Mayman, MD, senior author of the study, orthopedic surgeon at Hospital for Special Surgery in New York City told Orthopedics Today.

Mayman and colleagues used the State Ambulatory Surgery Databases and State Inpatient Databases for Florida and California to identify 7,351 patients who underwent hip arthroscopy and had 2-year follow-up. The investigators calculated the rate of conversion to total hip arthroplasty (THA) and determined risk factors for conversion.
Findings showed within 2 years after hip arthroscopy, 12.4% of patients underwent primary THA. Investigators noted patients younger than 40 years had the lowest conversion rate (3%), and patients 60 years to 69 years had the highest rate (35%).
According to researchers, older patients, patients with osteoarthritis and patients who were obese at time of hip arthroscopy had a greater chance of conversion to THA. Patients treated at high-volume centers for hip arthroscopy, compared with patients who underwent procedures at low-volume centers, had lower conversion rates. ‒ by Monica Jaramillo
