Hip arthroscopy for labral tears benefits patients on workers’ compensation
Patients with workers compensation status showed significant benefits from hip arthroscopy for the treatment of labral tears, according to results of this study.
Researchers collected data on all patients who were treated with hip arthroscopy between June 2008 and August 2010. The study included 21 hips from 20 patients who had a labral tear and were receiving workers compensation (WC). Researchers matched the WC group with a control group who were selected according to age with 3 years, gender, surgical procedures and radiographic findings.
All patients were assessed preoperatively and postoperatively with the modified Harris Hip Score (mHHS), the Non-Arthritic Hip Score (NAHS), the Hip Outcome Score – Activities of Daily Living (HOS-ADL) and the Hip Outcome Score – Sport-Specific Subscales (HOS-SSS). Pain was estimated on the VAS and satisfaction was measured on a scale from zero to 10.
Patients with WC status had significantly lower preoperative patient-reported outcome scores for all measures. However, researchers found no significant difference in VAS pain scores between groups. Overall, 86% of WC patients returned to work at a median of 82 days postoperatively. From preoperative to 2-year follow-up, the WC group had improved scores of 46 to 67.7 for mHHS, 39.3 to 66 for NAHS, 39.7 to 69.5 for HOS-ADL, and 15.3 to 49.8 for HOS-SSS. The control group showed score improvement of 67.9 to 85.8 for mHHS, 62.6 to 84.4 for NAHS, 69.8 to 86.9 for HOS-ADL and 41.9 to 73.8 for HOS-SSS.
Pain scores decreased from 7 to 3.9 in the WC group and from 5.8 to 3.2 in the control group. Patient satisfaction was 6.8 for the WC group and 7.7 for the control group. Neither pain scores nor patient satisfaction scores were significantly different between groups.
