Abstract Background Juvenile hip osteoarthritis is often the end result of congenital conditions or acquired hip ailments occurred during the paediatric age. This study evaluated the middle term results of total hip arthroplasty for end-stage juvenile hip osteoarthritis. Materials and methods This is a retrospective analysis of prospectively collected data on a cohort of 10 consecutive patients (12 hips), aged between 14 and 20 at operation, who underwent cementless total hip arthroplasty for end-stage juvenile secondary hip osteoarthritis in two orthopaedic tertiary referral centres between 2009 and 2018. Results Juvenile hip osteoarthritis occurred as a consequence of developmental dysplasia of the hip, Legg-Calvé-Perthes disease, femoral head necrosis or slipped capital femoral epiphysis. All patients showed a significant improvement in Harris Hip Score (p < 0.01) at 3.3 years average follow-up (range 0.7–10.1 years). Conclusion The management of juvenile hip osteoarthritis following developmental dysplasia of the hip, Legg-Calvé-Perthes disease, femoral head necrosis or slipped capital femoral epiphysis is still challenging. Careful preoperative planning is essential to achieve good outcomes and improve the Harris Hip Score in these young patients. Total hip arthroplasty is a suitable option for end-stage secondary juvenile hip osteoarthritis, when proximal femoral osteotomies and conservative treatments fail to improve patients’ symptoms and quality of life.

Abstract Background: High hip center technique is still controversial about the survivorship of prothesis and postoperative complications. We aimed to show the utility of high hip center technique used in patients with Crowe II-III developmental dysplasia of the hip at the midterm follow-up and evaluated the clinical and radiographic results between different heights of hip center.Methods: We retrospectively evaluated 69 patients (85 hips) with Crowe II-III dysplasia who underwent a high hip center cementless total hip arthroplasty at a mean follow up of 8.9 years (range, 6.0-14.1years). The patients were divided into two groups according to the height of hip center, respectively group A (≥22mm and <28mm) and group B (≥28mm). Radiographic, functional and survivorship outcomes were evaluated.Results: There were no statistically significant differences between two groups in horizontal distance, offset, abductor lever arm, leg length discrepancy and cup inclination. At the final follow up, the mean WOMAC and Harris hip score were significantly improved in both groups. Of the 85 hips, 7 hips (8.2%) showed a positive Trendelenburg sign. Besides, 6 patients (8.7%) presented with a limp. No significant differences were shown regarding the Harris hip score, WOMAC score, Trendelenburg sign and limp between two groups. The Kaplan-Meier implants survivorship rates at the final follow-up for all-causes revisions in group A and group B were similar (96.7% [95% confidence interval, 90.5%-100%] and 96.2% [95% confidence interval, 89.0%-100%], respectively).Conclusions: The high hip center technique is a valuable alternative to achieve excellent midterm results for Crowe II-III developmental dysplasia of the hip.

Abstract Purpose To restore rotation center exactly in total hip arthroplasty (THA) is technically challenging for patients with end-stage osteoarthritis due to developmental dysplasia of the hip (DDH). The technical difficulty is attributable to the complex acetabular changes. In this study, we investigated the pathomorphology of acetabulum and Harris fossa of Crowe types I to IV and discussed the method of restoring rotation center of the hip. Methods This study retrospectively reviewed 56 patients (59 hips) who underwent cementless THA due to end-stage osteoarthritis of DDH. The pathomorphology of acetabulum and Harris fossa was observed during operations. Using the preoperative and postoperative pelvic radiographs, the vertical and the horizontal distances of hip rotation center were measured in order to evaluate the effects of restoring rotation center of the hip. Results Adult DDH acetabulum could be classified into four basic pathological types which include the shallow cup shape, the dish shape, the shell shape, and the triangular shape. Adult DDH Harris fossa could be classified into four pathological types, including the crack shape, the closed shape, the triangle shape, and the shallow shape, in accordance with the osteophyte coverage. The vertical and horizontal distances of hip rotation center on the pelvic radiographs before and after operations were as follows: the preoperative vertical distance of hip rotation center was (39.96 ± 5.65) mm, and the postoperative one was (13.83 ± 2.66) mm; the preoperative horizontal distance of hip rotation center was (42.15 ± 6.42) mm, and the postoperative one was (28.12 ± 4.56) mm. Conclusions The acetabulum and Harris fossa can display different pathological types on account of different degrees of dislocation and osteophyte hyperplasia in the end-stage osteoarthritis of adult DDH. The hip rotation center can be accurately restored by locating the acetabular center with Harris fossa and acetabular notch as the marks.

At the final follow up, the WOMAC and Harris hip scores were excellent in both groups. Of the 85 hips, 7 (8.2%) showed a positive Trendelenburg sign. Besides, 6 patients (8.7%) had a symptom of claudication. No significant differences were shown regarding the Harris hip score, WOMAC score, Trendelenburg sign and claudication between two groups. The Kaplan-Meier 8-year implants survivorship rates for all-causes revisions in group A and group B were similar (96.7% [95% confidence interval, 90.5%-100%] and 96.2% [95% confidence interval, 89.0%-100%], respectively).Conclusions: The high hip center technique is a valuable alternative to achieve excellent midterm results for Crowe II-III developmental dysplasia of the hip, preferably combined with COC interface or high crosslinked polyethylene liner.

Abstract Background This study aimed to explore mid-term clinical results of cementless total hip arthroplasty (THA) with modified trochanteric osteotomy in Crowe type IV developmental dysplasia of the hip (DDH). Methods Thirteen patients (13 hips) with Crowe type IV DDH who underwent THA with modified trochanteric osteotomy between May 2013 and October 2015 were retrospectively analyzed. The mean follow-up duration was 5.2 years (range, 4.9–6.1 years). Results The mean Harris Hip Score (HHS) significantly (p < 0.05) improved from 30.7 (range, 22–38) to 87.5 (range, 83–93). The mean leg length discrepancy (LLD) was 53.4 mm (range, 42.1–68.5 mm) preoperatively. The final LLD was 5.6 mm (range, 2.4–9.1 mm; p < 0.05). The mean leg length after surgery was 47.4 mm (range, 33.6–67.2 mm) and the femur shortening distance was 43.8 mm (range, 31.2–53.4 mm). The average duration of bone union for the greater trochanter (GT) was 2.5 months (range, 1.5–3.6 months). There was no infection, GT non-union, or loosening (septic or aseptic) of the stem or cup in any case. Conclusions THA with modified trochanteric osteotomy with a cementless cup is an effective treatment for Crowe type IV DDH. It can rebuild complex biomechanics and biology of hip dysplasia without increasing complications.

Objective This study was performed to document the clinical and radiographic results of consecutive patients with Crowe IV developmental dysplasia of the hip (DDH) treated by cementless total hip arthroplasty (THA) using an S-ROM femoral component with shortening derotational subtrochanteric osteotomy. Methods Twenty-three hips of 21 patients with Crowe IV DDH were treated by cementless THA combined with shortening derotational subtrochanteric osteotomy from January 2005 to January 2011. The mean preoperative modified Harris hip score (mHHS) and University of California, Los Angeles (UCLA) activity score were 40.7 and 4.2, respectively. Results The mean follow-up was 105 months. The mean mHHS and UCLA score improved to 87.0 and 9.1, respectively, at the latest follow-up. Nine of the 23 hips had a negative Trendelenburg sign. One of the 23 hips was outside the Lewinnek acetabular cup inclination safe range, and 3 of the 23 hips were outside the Lewinnek acetabular cup anteversion safe range. The probability of prosthesis survival was 100% at 5 years and 91.3% at 10 years. Conclusion Patients with Crowe IV DDH can be treated by cementless THA combined with shortening derotational subtrochanteric osteotomy. This method can greatly improve hip joint function and relieve pain without significant complications.
