“…This increased risk of dislocation in THA after DDH is probably to be expected since DDH patients often have extreme anteversion of the proximal femur, which governs the anteversion of the femoral component and thereby increases the risk of anterior dislocation. Mortazavi et al reported that the dislocation rate was significantly higher in the DDH group than in the primary OA group [ 19 ]. Furthermore, a univariate analysis in the same study indicated an increase in the dislocation rate in relation to the severity and grade of DDH.…”

Purpose This systematic review and meta-analysis aimed to compare the outcomes of total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH) and those with osteoarthritis (OA). Methods Four databases were searched from inception till February 2023 for original studies that compared the outcomes of THA in DDH and OA. The primary outcome was the revision rate; the secondary outcomes were dislocation and failure modes (i.e. aseptic loosening, PJI, instability, and periprosthetic fractures), hospital stay and costs. This review was conducted as per PRISMA guidelines, and the risk of bias was assessed using the Newcastle–Ottawa scale. Results A total of 9 observational studies with 575,255 THA (469,224 hips) were included, with a mean age of 50.6 years and 62.1 years for DDH and OA groups, respectively. There was a statistically significant difference in revision rate between DDH and OA patients in favour of OA (OR, 1.66; 95% CI 1.11–2.48; p-value, 0.0251). However, dislocation rate (OR, 1.78, 95% CI 0.58–5.51; p-value, 0.200), aseptic loosening (OR, 1.69; 95% CI 0.26–10.84; p-value, 0.346) and PJI (OR, 0.76; 95% CI 0.56–1.03; p-value, 0.063) were comparable across both groups. Conclusion A higher revision rate following total hip arthroplasty was associated with DDH compared with osteoarthritis. However, both groups had similar dislocation rates, aseptic loosening and PJI. Consideration of confounding factors, such as patient age and activity level, is crucial when interpreting these findings. Level of evidence III. Trial registration PROSPERO registration: CRD42023396192.

“…Postoperative hip dislocation after THA is a typical complication and the primary cause of THA revision. Some studies of THA for secondary osteoarthritis in developmental dysplasia of the hip (DDH) exhibited different dislocation rates compared with those for primary osteoarthritis (pOA) 4,5 . DDH has been reported to display unusual pelvic morphology as well as different overall acetabular coverage 6,7 .…”

Bony impingement, especially in the anterior inferior iliac spine (AIIS) after total hip arthroplasty (THA), may cause dislocation. However, the influence of AIIS characteristics on bony impingement after THA is not fully understood. Thus, we aimed to determine the morphological characteristics of AIIS with developmental dysplasia of the hip (DDH) and primary osteoarthritis (pOA) and to evaluate its effect on range of motion (ROM) after THA. Hips from 130 patients who underwent THA, including pOA were analyzed. In total, we had 27 male and 27 female participants with pOA, and 38 male and 38 female participants with DDH. The horizontal distances of AIIS from teardrop (TD) were compared. In the computed tomography simulation, flexion ROM was measured, and its relationship to the distance between TD and AIIS was investigated. DDH had a more medial (male: DDH, 36.9 ± 5.8; pOA, 45.5 ± 6.1; p < 0.001) (female: DDH, 31.5 ± 10.0; pOA, 36.2 ± 4.7; p < 0.001) position of AIIS than pOA. In the male with pOA group, flexion ROM was significantly smaller than that in the other groups, and there was a correlation between flexion ROM and horizontal distances (r = −0.543; 95% confidence interval = −0.765 to −0.206; p = 0.003). AIIS position is a factor that limits ROM during flexion after THA, particularly in males. Further studies are required to develop surgical strategies for cases of impingement at the AIIS site after THA. Level of evidence: Ш, retrospective comparative study.
