Patients who had no pain in other joints, compared with patients with spine pain, had better hip outcome score activities of daily living values after hip arthroscopy at 2 years postoperatively, according to recently published results.

Researchers reviewed an institutional surgical registry and identified 821 patients who underwent hip arthroscopy between January 1, 2012, and July 16, 2015. Each of the 700 patients who completed the minimum 2-year follow-up were assigned a musculoskeletal morbidity score based on the presence of pain in other joints and the spine. The hip outcome score activities of daily living (HOS-ADL) was used to measure functional outcomes preoperatively and at 2 years postoperatively. Investigators calculated the percentages of patients who achieved minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS).

Results showed patients at MSM grade 1 had higher HOS-ADL compared with MSM grade 2. However, there was no difference seen MSM grade 1 and MSM grade 3 or between MSM grade 1 and MSM grade 4. Investigators noted preoperative HOS-ADL was not different among MSM grades 2, 3 and 5. Patients with MSM grades 1 and 2 were younger than patients with grades 3 and 4.

At the 2-year follow-up, patients with MSM grade 1 had higher HOS-ADL, compared with MSM grade 3 and grade 4. However, this was not the same for patients with grade 2. Eighty-four percent of patients showed MCID. PASS regarding HOS-ADL was achieved by 72% of patients. No statistically significant differences were seen among MSM grades regarding MCID or PASS. – by Monica Jaramillo
