“…Summarizing the statements provided in the review articles, essays, and case reports (Table 1), a few commonly reported traits can be made out: claimed radiographic signs of infection are periosteal reaction [23][24][25][26][27][28][29][30][31][32][33], formation of lamellae [23], focal osteolysis or bone destruction [7,23,24,26,28,31,[33][34][35][36][37][38], a wide radiolucent zone [23,32,36,39], signs of loosening in a previously well-fixed implant [24,27,28,32,34], heterotopic bone formation [28,40], mottling [31], an intracortical sinus tract [24,28], periprosthetic fractures [27], adjacent soft-tissue collection [29,30,32], and rapid disease progression [25]. Aseptic loosening tends to produce uniform radiolucency, whereas particle disease produces multifocal radiolucencies related to localized osteolysis.…”

Conventional radiography is regularly used to evaluate complications after total hip arthroplasty. In various recent consensus meetings, however, plain radiographs of a potentially infected hip joint have been judged as being only relevant to exclude diagnoses other than infection. Solid data on radiographic presentations of periprosthetic joint infection (PJI) are scarce. As a result, the prognostic value of radiological features in low-grade PJI remains uncertain. The present review article aims to present an overview of the available literature and to develop ideas on future perspectives to define the diagnostic possibilities of radiography in PJIs of the hip. The primary outcome of interest of this systematic review was the radiologic presentation of periprosthetic joint infections of the hip. As secondary outcome of interest served the sensitivity and specificity of the radiologic presentation of periprosthetic joint infections. Of the included articles, 26 were reviews, essays, or case reports and only 18 were clinical studies. Typical radiologic abnormalities of PJI were a periosteal reaction, a wide band of radiolucency at the cement–bone or metal–bone interface, patchy osteolysis, implant loosening, bone resorption around the implant, and transcortical sinus tracts. The frequency of their occurrence is still inadequately defined. A deeper understanding of the underlying causes and the relation between microorganisms to radiologic abnormalities can probably help clinicians in the future to diagnose a PJI. This is why further research shall focus on the radiographic features of PJI.

“…While THA is generally safe and effective, postoperative complications, including periprosthetic joint infections, dislocation, aseptic loosening, and periprosthetic fractures, often arise, leading to failure of the prosthesis ( Healy et al, 2016 ; Kelmer et al, 2021 ; Patel et al, 2023 ). The identification of these complications typically relies on plain radiographs ( Awan et al, 2013 ; Thejeel and Endo, 2022 ), which can be subjective, time-consuming, and prone to misdiagnosis. Therefore, a more accurate and timely method for detecting postoperative complications would help to optimize treatment planning and improve patient outcomes.…”

Background: Postoperative complications following total hip arthroplasty (THA) often require revision surgery. X-rays are usually used to detect such complications, but manually identifying the location of the problem and making an accurate assessment can be subjective and time-consuming. Therefore, in this study, we propose a multi-branch network to automatically detect postoperative complications on X-ray images.Methods: We developed a multi-branch network using ResNet as the backbone and two additional branches with a global feature stream and a channel feature stream for extracting features of interest. Additionally, inspired by our domain knowledge, we designed a multi-coefficient class-specific residual attention block to learn the correlations between different complications to improve the performance of the system.Results: Our proposed method achieved state-of-the-art (SOTA) performance in detecting multiple complications, with mean average precision (mAP) and F1 scores of 0.346 and 0.429, respectively. The network also showed excellent performance at identifying aseptic loosening, with recall and precision rates of 0.929 and 0.897, respectively. Ablation experiments were conducted on detecting multiple complications and single complications, as well as internal and external datasets, demonstrating the effectiveness of our proposed modules.Conclusion: Our deep learning method provides an accurate end-to-end solution for detecting postoperative complications following THA.
