Although obese patients undergoing hip arthroscopy started with lower absolute scores preoperatively and ended with lower overall absolute postoperative scores, they showed substantial benefit from surgery, demonstrating a degree of improvement similar to non-obese patients, according to study results.
Researchers assessed 680 patients undergoing primary hip arthroscopy preoperatively and postoperatively with four patient-reported outcome measures. The researchers estimated pain on the VAS and measured patient satisfaction scores. Five hundred sixty-two patients with a BMI of less than 30 kg/m2 were included in the non-obese group; 94 patients with a BMI of 30 kg/m2 to 34.9 kg/m2 were included in the class-I obese group; and 24 patients with a BMI of 35 kg/m2 to 39.9 kg/m2 were included in the class-II obese group.
Results showed a modified Harris hip score improvement from 63.41 at the preoperative assessment to 83.81 points at the 2-year follow-up visit for the non-obese group, from 54.81 to 75.95 points for the class-I obese group and of 50.81 to 80.01 points for the class-II obese group.
The researchers also found a Non-Arthritic Hip Score improvement of 60.86 to 83.62 points in the non-obese group, of 48.98 to 75.51 points for class-I obese group and of 42.36 to 72.5 points for the class-II obese group.
Within the non-obese group, the Hip Outcome Score – Activities of Daily Living improved from 66.24 to 86.24 points, and the Hip Outcome Score Sport – Specific Subscale improved from 44.01 to 73.26 points from preoperative assessment to 2-year follow-up compared with an improvement from 53.22 to 72.99 points for Activities of Daily Living and from 30.56 to 60.75 points for Sport-Specific Subscale in the class-I obese group and from 48.11 to 74.73 points for Activities of Daily Living and from 28.25 to 62.56 points for Sport-Specific Subscale in the class-II obese group.
Overall, traction time did not vary significantly between groups, according to the researchers. – by Casey Tingle
