2026 SLARD Annual Meeting: Changes in Peritrochanteric Space Pressure Following Gluteus Maximus Tenotomy

56 patients with peritrochanteric syndrome were randomized to undergo a gluteus maximus tenotomy of 1, 2, 3, 4, or 5 cm in length. Outcomes of interest included the absolute reduction in lateral hip compartment pressure (mmHg), relative pressure reduction (%), and intraoperative bleeding. Overall, the results of the study revealed that pressure reduction increased significantly as tenotomy length increased, with the greatest reductions observed in the 4 cm and 5 cm groups. However, bleeding risk also increased with longer tenotomies, particularly in the 4 cm and 5 cm groups. These findings suggest that a tenotomy length between 2 and 4 cm may provide the best balance between pressure reduction and bleeding risk.
