Abstract
dc.description.abstract
Developmental dysplasia of the hip (DDH) has been recognized to be a condition leading to osteoarthritis.
Periacetabular osteotomy (PAO) has showed good results on hip preservation treatment for these cases.
Nevertheless, intra-articular damage may be responsible for persistent post-operative symptoms, so treat the articular
damage before or during the PAO has emerged as an alternative to address it. The objective is to identify
the prevalence of intra-articular damage, functional outcomes of patients undergoing PAO with untreated
intra-articular lesions and the survivorship free total hip arthroplasty (THA) at long-term follow-up. A retrospective
review of 103 hips in 92 patients, mean age 26 years old (19–31), 96% females. Mean follow-up 7 years
(range: 3–16). Intra-articular damage was evaluated with high-resolution magnetic resonance imaging (MRI)
previous to perform the PAO, the chondral damage was evaluated using International Cartilage Repair Society
classification. Harris Hip Score (HHS) was obtained in all patients. One hundred per cent of the cases had labral
tears on MRI, hypertrophic labrum in 80.8% and paralabral cysts in 20.8%. Acetabular chondral damage
was Grade 2 in 88.5% of the hips. HHS was good and excellent in 94%. Survivorship free of THA at 15 years
was 87%. Chondrolabral damage is a common finding in patients with DDH. Despite that, excellent results are
obtained with PAO without labral repair. We think the focus should be in the biomechanical and anatomical
correction of the hip in patients with DDH.
