“…This assumption is supported by 2 other studies on CTACs that reported no dislocations and either used a dual mobility cup in all cases (Colen et al 2013) or a constrained liner in most of their cases (Berasi et al 2015). To our knowledge, only 2 other studies have measured the accuracy of the placement of their custom-made implant (Weber et al 2019, Zampelis andFlivik 2020). Both of them found similar good placement accuracy, as we have previously found (Baauw et al 2016), and had 1 and 0 dislocations in 11 and 10 patients, highlighting the importance of accurate placement to diminish the dislocation rate.…”

“…Another limitation is the fact that we cannot comment on the migration of the implant, which is difficult to determine for this particular implant on conventional radiographs. Recently, Zampelis and Flivik ( 2020 ) have determined the migration of a similar implant, same cage but without an augment, at 1-year follow-up using CT scans. They found small measured migration values of less than 1 degree or 1 mm.…”

“…In addition, this restores the typical biomechanical environment of the hip joint by reconstructing the hip anatomic center. Four studies [ 17 , 19 , 21 , 23 ] used COR as an indicator to evaluate radiological outcomes. These studies reported a reliable restoration of the hip’s center with the assistance of 3D printing.…”

“…The favorable reconstructed acetabular position (anteversion angle and abduction angle) can reduce the risk of postoperative dislocation. Three studies [ 17 , 19 , 21 ] investigated radiological outcomes according to the anteversion angle, abduction angle, and other indicators. These publications both reported well reconstructed acetabular cup positions within the tolerance for error.…”

Clinical and radiological outcomes in three-dimensional printing assisted revision total hip and knee arthroplasty: a systematic review

Background This study investigates whether three-dimensional (3D) printing-assisted revision total hip/knee arthroplasty could improve its clinical and radiological outcomes and assess the depth and breadth of research conducted on 3D printing-assisted revision total hip and knee arthroplasty. Methods A literature search was carried out on PubMed, Web of Science, EMBASE, and the Cochrane Library. Only studies that investigated 3D printing-assisted revision total hip and knee arthroplasty were included. The author, publication year, study design, number of patients, patients’ age, the time of follow-up, surgery category, Coleman score, clinical outcomes measured, clinical outcomes conclusion, radiological outcomes measured, and radiological outcomes conclusion were extracted and analyzed. Results Ten articles were included in our review. Three articles investigated the outcome of revision total knee arthroplasty, and seven investigated the outcome of revision total hip arthroplasty. Two papers compared a 3D printing group with a control group, and the other eight reported 3D printing treatment outcomes alone. Nine articles investigated the clinical outcomes of total hip/knee arthroplasty, and eight studied the radiological outcomes of total hip/knee arthroplasty. Conclusion 3D printing is being introduced in revision total hip and knee arthroplasty. Current literature suggests satisfactory clinical and radiological outcomes could be obtained with the assistance of 3D printing. Further long-term follow-up studies are required, particularly focusing on cost-benefit analysis, resource availability, and, importantly, the durability and biomechanics of customized prostheses using 3D printing compared to traditional techniques.

In revision total hip arthroplasty, achieving robust fixation is difficult and implant movement may occur over time. Bone may also rearrange around the implant as a result of mechanical loading, making the measurement of migration challenging. The study aimed to quantify changes in bone shape and implant position 1 year following acetabular reconstruction using custom three‐dimensional‐printed cups. This observational retrospective cohort study involved 23 patients with Paprosky type IIIB defects. Postop computed tomography scans taken within 1 week of surgery and at 1‐year postsurgery were co‐registered and analyzed. Three co‐registration strategies were implemented including bone‐to‐bone and implant‐to‐implant. (1) Co‐registration of the ipsilateral innominate bone (diseased anatomy) was used to measure changes in implant position. (2) Co‐registration of the implant was carried out to quantify changes in the ipsilateral innominate bone shape. (3) Co‐registration of the contralateral innominate bone (nondiseased anatomy) was performed to measure changes in the ipsilateral innominate bone shape and implant position. The median centroid distances (interquartile range [IQR]) were 2.3 mm (IQR: 3.7–1.7 mm) for changes in implant position, 2.4 mm (IQR: 3.6–1.6 mm) for changes in ipsilateral innominate bone shape, and 3.7 mm (IQR: 4.6–3.5 mm) for changes in ipsilateral innominate bone shape and implant position. Following acetabular reconstruction, implant movements and periprosthetic bone remodeling are physiological and of a similar extent. Surgeons and engineers should consider this when performing implant monitoring in these patients.
