Purpose
The aim of this study was to assess complications related to arthroscopy for femoroacetabular
impingement (FAI) and how these complications have changed as we have gained more
experience with this procedure.
Methods
The authors reviewed 200 hips (197 patients). The average patient age was 44.64 years
and the mean follow-up time was 28.2 months. All patients underwent hip arthroscopy
in the supine position. Clinically, Modified Harris Hip Scores (MHHS) and patient
satisfaction with outcome were used. We divided complications into 3 groups: Group
1 related to traction, group 2 related to surgical technique or implant failure, and
group 3 related to outcomes.
Results
Clinically, the MHHS improved from 69.96 (±6.10) to 80.45 (±7.00), and patient satisfaction
with the achieved outcome increased to 8.87 (±0.76). The overall complication rate
was 15% (30 of 200 hips). Group 1 consisted of 4 patients with pudendal neuropraxia
and 2 patients with ankle joint pain (P = .013). Group 2 consisted of 2 patients with lateral femoral cutaneous neuropraxia,
2 patients with iatrogenic labral perforations, one patient with a labral tear, and
4 patients with femoral head scuffs. There were 4 incidents of instrument breakage.
Furthermore, 3 suture anchors failed, a second-degree burn occurred in one patient,
and there was incomplete reshaping in 5 hips (P = .045). Group 3 included one patient with a snapping sound and heterotopic ossification.
Second-look arthroscopy was performed for 5 hips. All the complications outlined in
groups 1 and 2 are related to the learning curve and have statistical significance
(P < .05).
Conclusions
Complications relating to hip arthroscopy took different forms during the early learning
period, but overall complication rates decreased along the learning curve. Surgical
technique–related complications such as problems with suture anchors and the reshaping
of cam impingements were also considered during the later stage.
Level of Evidence
Level IV, therapeutic case series.
