Purpose
To determine whether increased joint hypermobility, quantified by the Beighton score,
is associated with a greater incidence of iliopsoas tendinitis (IPT) in postoperative
hip arthroscopy patients treated for femoroacetabular impingement (FAI).
Methods
We conducted a retrospective chart review of patients who underwent hip arthroscopy
for labral repair and FAI from 2016 to 2020 for whom at least 12 months of follow-up
data were available. The Beighton score was measured by a blinded, independent reviewer.
IPT was clinically diagnosed by a sports medicine fellowship–trained orthopaedic surgeon
through physical examination. Patients with a diagnosis of IPT were matched at a 1:1
ratio to controls based on age, sex, and body mass index. Demographic characteristics,
radiographs and advanced imaging, surgical characteristics, and corticosteroid injection
therapy data were obtained via chart review. Statistical analysis was conducted using
Mann-Whitney testing and binary logistic regression.
Results
Forty patients in whom postoperative IPT developed were identified and matched to
40 control patients in whom postoperative tendinitis did not develop. Increased joint
hypermobility, quantified by the Beighton score, was associated with an increased
risk of IPT. For each 1-point increase in the Beighton score, there was a 1.69 (95%
confidence interval, 1.25-2.29; P < .001) increased odds of IPT development postoperatively. A high (≥4) versus low
(<4) Beighton score was associated with an increased likelihood of tendinitis (odds
ratio, 9.82; 95% confidence interval, 2.79-34.58; P < .001). However, there was no association between greater Beighton scores and patients’
likelihood of receiving a corticosteroid injection (P = .173).
Conclusions
Increased joint hypermobility, quantified by the Beighton score, is associated with
an increased risk of IPT developing in the hip arthroscopy postoperative period in
patients treated for FAI and labral pathology.
