Purpose:
To compare a single surgeon's first 200 cases of hip arthroscopy with the last 200 cases regarding patient demographic characteristics, indications for surgery, intraoperative findings, procedures performed, and patient-reported outcomes.
Methods:
Data were reviewed for all patients undergoing primary hip arthroscopy between February 2008 and August 2016 performed by a single surgeon. Of the 3,319 patients who underwent hip-preservation surgery during the study period, the first 200 (group A) and last 200 (group B) eligible for minimum 2-year follow-up were included in our analysis.
Results:
Follow-up was available for 187 of 200 patients (93.5%) and 189 of 200 patients (94.5%) in groups A and B, respectively. The groups were similar in age, sex, and body mass index (P > .05). Group A included significantly more patients with Tönnis grade 1 (37% vs 21%, P < .001). Group B consisted of significantly more (P < .001) labral reconstructions (10.2% vs 0%), capsular closures (72.7% vs 26.2%), and gluteus medius repairs (18.2% vs 3.2%). Femoroplasty was performed for smaller cam lesions in group B, resulting in smaller postoperative alpha angles (45.7° ± 7.9° vs 42.4° ± 6.3°, P < .001). Group B exhibited significantly higher patient-reported outcomes at minimum 2-year follow-up (P < .05). In addition, in group B, greater proportions of patients achieved the minimal clinically important difference and patient acceptable symptomatic state (P < .05).
Conclusions:
This study shows the noteworthy evolution in the management of the prearthritic adult hip occurring between 2008 and 2016. This includes improvements in preoperative patient evaluation and patient selection. In addition, the proportion of patients undergoing labral reconstruction, capsular plication, and femoroplasty has increased significantly. These developments, as well as increased surgical experience, may have contributed to improved surgical outcomes.
Level Of Evidence:
Level III, retrospective comparative trial.
