Key takeaways:

Young adults with borderline hip dysplasia who underwent hip arthroscopy had favorable results.
Higher BMI and age 42 years or older were associated with increased risk for conversion to total hip arthroplasty.

Young adults with borderline hip dysplasia who underwent primary hip arthroscopy saw favorable outcomes after a minimum 10-year follow-up, according to study results published in The Journal of Bone & Joint Surgery.

Benjamin G. Domb, MD, of the American Hip Institute and American Hip Institute Research Foundation in Chicago, and colleagues prospectively collected survivorship, defined as no conversion to total hip arthroplasty, and patient-reported outcome measures from 45 hips of patients (mean age, 31 ± 12.9 years) who underwent primary hip arthroscopy with capsular plication and labral preservation for borderline hip dysplasia between September 2008 and September 2011. Researchers collected patient-reported outcome measures (PROMs), including the modified Harris Hip Score, nonarthritic hip score, hip outcome score-sports specific subscale (HOS-SSS) and VAS pain scale, at 1 month prior to surgery and postoperatively at 3 months, 1 year and annually thereafter.

According to the study, patients had a 10-year survivorship rate of 82.2% with improvements in every PROM, as well as VAS pain scale.

Meanwhile, patients with a BMI of 23 kg/m² or greater had a four times greater risk for conversion to THA, and the risk for patients aged 42 years or older increased by seven times.

In addition, the achievement rate for the minimal clinically important difference was 79% for modified Harris Hip Score, 79% for the nonarthritic hip score, 70% for the HOS-SSS and 76% for VAS pain scale.

“Borderline hip dysplasia remains a challenging condition to treat successfully arthroscopically, and adequate capsular plication remains a highly technique-dependent procedure,” the researchers wrote in the study.
