Study: ACL reconstruction reduced patient bone mineral areal mass in calcanei, hips
Researchers found both male and female patients who underwent ACL reconstruction lost bone mineral areal mass at 5-year follow-up in both calcaneal and hip bones, according to results of this study.
“Both female and male patients had a significant decrease in [bone mineral areal mass] BMA in both calcanei and both hips during the 5-year study period compared with a reference population of Swedish healthy women and men,” Sven Sterner, MD, and colleagues wrote in the study. “The patients increased their Tegner activity level and improved their [health-related quality of life] HRQoL and EQ-5D index during the 5-year follow-up period.”
Sterner and colleagues examined BMA results from 48 patients who underwent ACL reconstruction using dual-energy X-ray absorptiometry on both the surgical and contralateral hip and calcaneal bones, according to the abstract. The measurements were taken preoperatively and at 6-month, 18-month, 36-month and 60-month follow-up.
At 5 years, females lost 9.5% BMA in the calcanea on the surgical side and 10.1% on the contralateral side. Male patients lost 6.5% BMA in the surgical side and 8.5% on the contralateral side, according to the abstract. In surgical side and contralateral hips, female patients lost 4% and 2.7% of their BMA, respectively, while males lost 3.4% and 4.8% of their BMA in the surgical side and contralateral hips, respectively.
