“…Although several previous studies demonstrated the accuracy of cup alignment after THA, few studies used 3D parameters to analyze the acetabular component position in patients with DDH. 9 , 41 The reproducibility of the positioning of the acetabular component is crucial for adjusting leg length and offset, especially in patients with DDH with leg length discrepancy and subluxation. Further, accurate cup position can preserve both the anterior and posterior walls of the acetabulum, which is critical for stable cup fixation and outcomes of acetabular reconstruction in revision surgery.…”

“…Although a systematic review and meta-analysis study demonstrated that no significant differences in pain, quality of life, and satisfaction were found between computer-assisted THA and conventional THA, 10 computerized navigation THA achieved precise cup position and decreased complications within 90 days postoperatively. 9 , 11 Previous studies have demonstrated the accuracy of cup placement in DDH patients with CT. 12 , 13 Moreover, a navigation system has been used not only for THA but also for hip resurfacing arthroplasty, periacetabular osteotomy, and stem cell therapy in osteonecrosis of the hip. 14 - 17 …”

Aims This study aimed to evaluate the accuracy of implant placement with robotic-arm assisted total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH). Methods The study analyzed a consecutive series of 69 patients who underwent robotic-arm assisted THA between September 2018 and December 2019. Of these, 30 patients had DDH and were classified according to the Crowe type. Acetabular component alignment and 3D positions were measured using pre- and postoperative CT data. The absolute differences of cup alignment and 3D position were compared between DDH and non-DDH patients. Moreover, these differences were analyzed in relation to the severity of DDH. The discrepancy of leg length and combined offset compared with contralateral hip were measured. Results The mean values of absolute differences (postoperative CT-preoperative plan) were 1.7° (standard deviation (SD) 2.0) (inclination) and 2.5° (SD 2.1°) (anteversion) in DDH patients, and no significant differences were found between non-DDH and DDH patients. The mean absolute differences for 3D cup position were 1.1 mm (SD 1.0) (coronal plane) and 1.2 mm (SD 2.1) (axial plane) in DDH patients, and no significant differences were found between two groups. No significant difference was found either in cup alignment between postoperative CT and navigation record after cup screws or in the severity of DDH. Excellent restoration of leg length and combined offset were achieved in both groups. Conclusion We demonstrated that robotic-assisted THA may achieve precise cup positioning in DDH patients, and may be useful in those with severe DDH.

Background: A few previous studies have investigated patient satisfaction after total hip arthroplasty (THA) according to the degree of pelvic deformity. This study compared patient-reported outcomes after primary THA for Crowe types III, IV and I dysplasia. Methods: This retrospective, single-center, single-surgeon case-control study included patients who underwent primary THA between 2008 and 2016. We sent postal questionnaires to 38 patients with Crowe type III and IV dysplasia. Among the questionnaire respondents, 23 patients, excluding those with a follow-up period of < 1 year, were enrolled as the H group. The control group included 46 patients with Crowe type I, matched for sex, age, body mass index and surgical approach. To investigate the influence of femoral shortening osteotomy, the H group was divided according to whether femoral shortening osteotomy was performed. Ten patients underwent THA with femoral shortening osteotomy (FO group), while 12 patients underwent THA without femoral shortening osteotomy (N-FO group). Patient demographics, mean follow-up period, surgical information, pre-and postoperative leg length discrepancy (LLD), and perioperative complications were investigated. Clinical evaluations were performed using the Japanese Orthopaedic Association (JOA) scores, 36-item short-form survey (SF-36), net promotor score (NPS), visual analogue scale (VAS), and questionnaires. The VAS and SF-36 scores were determined only at final follow-up.

Background: A few previous studies have investigated patient satisfaction following total hip arthroplasty (THA) according to the degree of pelvic deformity. This study compared patient-reported outcomes following primary THA for Crowe types Ⅲ, Ⅳ and I dysplasia.Methods: This was the retrospective case-control study assessed patients who underwent primary THA by a single surgeon at a single institution from 2008 to 2016. We sent postal questionnaires to 38 patients with Crowe type III and IV dysplasia. Among the questionnaire respondents, 23 patients, excluding cases with a follow-up period of less than 1 year, were enrolled as the H group. The control group included 46 patients with Crowe type I, matched for sex, age, body mass index and surgical approach. To investigate the influence of femoral shortening osteotomy, the H group was divided according to whether or not femoral shortening osteotomy was performed. Ten patients underwent THA with femoral shortening osteotomy (FO group), while 12 patients underwent THA without femoral shortening osteotomy (N-FO group). Patient demographics, average follow-up period, surgical information, pre- and postoperative leg length discrepancy (LLD), and perioperative complications were investigated. Clinical evaluations were performed using the Japanese Orthopaedic Association (JOA) scores, 36-item short-form survey (SF-36), net promotor score (NPS), visual analogue scale (VAS), and questionnaires. The VAS and SF-36 was acquired at only final follow-up. Results: The H and control groups were not significantly different in the postoperative JOA scores and SF-36. In the H group, VAS at the final follow-up was significantly higher, and significantly more patients felt that postoperative rehabilitation was serious, expressing that they underwent THA for LLD correction. Additionally, VAS in the FO group was higher than those in the N-FO group. Postoperative LLD was significantly greater in the H group than in the control group. Each group had the NPS of over 50.Conclusion: The postoperative VAS was higher in Crowe type Ⅲ and Ⅳ dysplasia than in Crowe type I dysplasia, but there were no significant differences in the postoperative satisfaction, JOA score and SF-36. The findings may help explain the effects of THA preoperatively to patients with Crowe type Ⅲ and Ⅳ dysplasia.Level of Evidence: Therapeutic Level 3b
