Abstract
Background
There is a paucity of literature evaluating the outcomes of adolescent patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) with a discrete traumatic event related to an injury.
Purpose
The purpose of this study is 1) to evaluate 5-year outcomes of adolescents undergoing hip arthroscopy for FAIS with traumatic injuries and 2) to compare the traumatic group to a propensity matched control group of patients with atraumatic injuries.
Methods
Data were reviewed for all adolescent patients (< 18 years) undergoing primary hip arthroscopy for FAIS with a traumatic injury between November 2008 and March 2015. Patients were included if they had Modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), hip outcome score-sport specific subscale (HOS-SSS), and visual analog scale for pain (VAS) at preoperative and at a minimum 5-year follow up. The patient acceptable symptom state (PASS), minimum clinically important difference (MCID), and maximum outcome improvement satisfaction threshold (MOIT) were also calculated for both groups. Traumatic injury adolescents (TI) were propensity-matched in a 1:2 according to age at surgery, sex, and body mass index (BMI) to a control group of adolescents that reported atraumatic hip symptoms (AHS). Survivorship was defined as having no secondary surgery on the ipsilateral hip.
Results
A total of 31 TI patients (32 hips) out of 39 patients (40 hips) (80%) were included with a mean follow-up time of 72.2 ± 24.1 months and age of 15.8 ± 1.3 years. The TI group demonstrated significant improvement in all PROs (P < 0.001) and demonstrated high rates of MCID (78.3%) and PASS (91.3%) for the mHHS. When compared to a propensity-matched control group of 64 AHS hips (57 patients), the TI group demonstrated similar rates of improvement in all PROs, as well as rates of achieving MCID, PASS, and MOIT for all PROs; however, the TI group demonstrated significantly higher revision rates compared to controls (28.1% vs 6.2%), P = 0.008).
Conclusions
Adolescent patients with traumatic injuries undergoing hip arthroscopy demonstrated favorable outcomes for all PROs (P< 0.001) and achieve high rates of MCID (78.3%) and PASS (91.3%) for the mHHS. When compared to a propensity-matched control group of adolescents with atraumatic injuries undergoing hip arthroscopy, they achieved similar levels of improvement, postoperative scores, and clinical benefit thresholds; however, reoperation rates were higher in the traumatic injury group compared to controls.
