Research and error risk assessments were performed by one author. Any duplicates or obsolete information were removed. Afterwards, every selected article was verified another time. If there occurred any signs of unreliability or relation to the topic were insignificant, the articles were eliminated during further evaluation. All studies presenting procedures conducted on animals were also excluded. As terms of exclusion non-English language articles, papers ahead of print and only titles or abstract available were chosen. Inclusion of the articles was determined on the basis of titles, then abstracts, eventually entire articles. Research was focused on English language papers, available abstracts, studies performed on people and articles. Therefore publications including keywords such as total hip replacement, center of rotation, femoral offset, acetabular offset, cup anteversion, cup inclination and leg length discrepancy were searched in the PubMed database. Articles related to the subject, published in the years 1978–2021 were researched. Each one of them, in varying degrees, can affect the outcome of the surgery. Multiple mechanical and biomechanical factors, such as center of rotation (COR), femoral offset, acetabular offset, acetabular inclination (AI), acetabular anteversion and leg length discrepancy can be measured on radiographs.

What is more, the application of this imaging technique is not associated with the artifacts caused by metal implants, in contrast to the use computed tomography or magnetic resonance.Īim of this article is to indicate which constituents can be measured on postoperative radiographs and point out how to interpret obtained results. In connection with this, in the majority of cases, radiographs are perfectly adequate. They include tendinopathy, implants loosening, persistent postoperative pain or other conditions that are hard or even impossible to detect using computed tomography and classical radiography. However, there are situations in which magnetic resonance imaging is helpful to obtain a diagnosis. There is also one method of imaging-magnetic resonance imaging, which is far less accessible and more expensive than previously mentioned imaging modalities. It is certainly more accurate than radiographs, but it has its limitations, such as radiation dose and limited availability. Computed tomography can be used for postoperative assessment as well. Its advantage over other imaging methods results also from the lowest price. Classical radiography is associated with a lower dose of radiation in comparison to computed tomography. It is the most widespread and commonplace method. In everyday clinical practice, radiographs are the most widely used tool for imaging. It is most often caused by the impact of mechanical aspects of THR on clinical outcome. Unfortunately, there still exists a group of patients, which does not derive any advantage from THR. Not only is it cost-effective treatment, but what is more important it is a very successful one, which relieves patients from pain, improves their quality of life and restores decreased range of motion. There were 98.649 hip replacement procedures performed in 2019 in the United Kingdom. Total hip replacement (THR) is one of the most widely performed surgeries.
