Similar results seen with endoscopic transcapsular release for single, multiple snapping tendons
In a study of patients who underwent endoscopic transcapsular release for internal snapping hip syndrome, investigators found 17.85% of cases had multiple tendons and they discovered patients with single snapping tendons had outcomes comparable to patients with multiple snapping tendons.
Researchers prospectively followed 28 patients with a mean age 29.25 years who had internal snapping hip syndrome treated with central transcapsular iliopsoas tendon release after failure of conservative treatment. Investigators intentionally searched for the presence of a bifid iliopsoas tendon during the surgery and discovered four patients who presented with a bifid iliopsoas tendon; one patient who presented with three tendons; and 23 patients had no bifid tendon. Patients with a bifid iliopsoas and the one patient with three tendons were categorized as group 1, and the remaining patients were categorized in group 2. Patients had a minimum follow-up of 12 months and a mean follow-up of 30.57 months.
Results at the 1-year follow-up showed no recurrence of snapping or pain in any patients. Investigators found group 1 had a mean preoperative WOMAC score of 39 points and after surgery the score was 73.6 points. Group 2 had a mean preoperative WOMAC score of 47.21 points and postoperatively the score was 77.91 points.
From the MRI retrospective analysis, investigators noted they identified a bifid iliopsoas tendon in three of the five cases in group 1; however, none were seen prior to surgery. Additional revision surgery was not needed in any patients, according to researchers. ‒ by Monica Jaramillo
