Background: Total hip arthroplasty (THA) is maintained as the conventional therapy when advanced osteoarthritis (OA) causes considerable
pain and functional impairment. Methods: This essay research presents an overview of the present understanding regarding THA in hips affected
by developmental dysplasia. In assessing the effect of THA on developmental dysplasia of the hip (DDH), numerous outcome metrics were
utilized, such as the frequency of revision procedures, the rate of dislocations, and the reasons for treatment failure. With regard to revision
surgeries, individuals with DDH have a 1.66 times higher likelihood of needing revisions compared to those with OA. Results: Aseptic loosening
and periprosthetic joint infection (PJI) were the only failure modes analyzed quantitatively, with three studies each reporting these outcomes.
DDH patients were 1.69 times more probable to experience aseptic loosening and 0.76 times less probable to have PJI, but both rates were not
statistically significant. Three studies provided data on hospitalization and costs, with stays ranging from 3 to 11 days. One study reported no
revisions or loosening of components over a follow‑up of 5–10 years, suggesting that cementless THA with double‑chevron subtrochanteric
osteotomy can effectively restore anatomic hip center and safely lengthen limbs. Conclusion: The investigation elucidated a conspicuously
heightened rate of revision in subjects diagnosed with DDH subsequent to THA. Albeit, the incidences of dislocation, aseptic loosening, and
PJI did not achieve statistical significance. This observation necessitates cautious interpretation, considering the diversity inherent within the
patient cohort and the potential influence of confounding variables. |
