Patients With Borderline Hip Dysplasia Achieve Clinically Significant Outcome After Arthroscopic Femoroacetabular Impingement Surgery: A Case-Control Study With Minimum 2-Year Follow-up

Abstract: Background: There is a growing trend for hip arthroscopists to treat patients with borderline hip dysplasia (BHD) for femoroacetabular impingement syndrome (FAIS) without addressing the acetabular coverage. However, the literature of outcomes and failure rates for these patients is conflicting. Purpose: (1) To identify whether patients with BHD achieved 2-year similar patient-reported outcome, minimal clinically important difference (MCID), and patient acceptable symptomatic state (PASS) when compared with pat… Show more

“…As such, patients were considered to have achieved MCID if they achieved the respective outcome end point on at least 1 of the administered questionnaires. 49 Our methodology here is in line with adopted and accepted FAI, KINESIOPHOBIA, AND PAIN CATASTROPHIZING e99 methods previously reported and supported in the literature. 45,[49][50][51][52] Statistical Analysis All data were screened to determine whether parametric statistical assumptions were met before analysis.…”

“…Inclusion criteria consisted of clinical and radiographic diagnosis of symptomatic FAIS, 13 failure of nonoperative management (physical therapy, activity modification, oral anti-inflammatory agents, and intra-articular cortisone injection), and a minimum 5-year follow-up. Exclusion criteria consisted of hip arthroscopy for an indication other than FAIS, previous ipsilateral hip surgery, signs of osteoarthritis (Tönnis grade >1), hip dysplasia (lateral center-edge angle of Wiberg [LCEA] <20°), 1 or a history of pediatric hip disorders (slipped capital femoral epiphysis, developmental hip dysplasia, avascular necrosis, etc).…”

“…The most lateral point of the acetabulum rather than the sourcil edge is often used, which would cause a typical mistake with a falsely high LCEA value. 35 Besides, the congenital difference in LCEAs between male and female populations must not be neglected, 1,7 which might have resulted in the superior outcomes of the female BDDH patients shown in the current review by Kuroda et al 25 Although an LCEA slightly less than 25 may represent a significant structural abnormality in male patients, it is possibly a normal anatomic variant in female patients. 1,7,25 This difference clearly indicates a need to set different criteria for BDDH based on sex.…”

“…First, patients with real BDDH should be distinguished and selected. Normally, BDDH is defined by a lateral center-edge angle (LCEA) between 20 and 25 1,2,[10][11][12][13]17,21,23,[29][30][31][32] or between 18 and 25 according to some modifications. [3][4][5][7][8][9]15,18,20,33 Because the diagnosis of BDDH relies primarily on a small range of LCEAs, even a minor offset can cause misdiagnosis, leading to the heterogeneity of the BDDH cohort.…”
