Article Synopsis
- The study investigates preoperative risk factors for iliopsoas tendonitis following total hip arthroplasty, focusing on factors like acetabular cup positioning using simulations from CT scans and X-rays of 448 patients.
- A significant 23% of patients were found to be at risk, with critical parameters like standing pelvic tilt and the difference in size between the planned acetabular cup and the native femoral head showing notable variations between at-risk and not-at-risk groups.
- Findings indicate that adjusting acetabular cup anteversion can help lower impingement risk more effectively than medialisation, providing surgeons with guidelines in preoperative planning to minimize iliopsoas tendonitis during hip replacement procedures.
Article Synopsis
- Iliopsoas tendonitis occurs after total hip arthroplasty (THA) in about 18% of patients and in up to 30% after hip resurfacing arthroplasty (HRA), mainly due to impingement with the acetabular cup.
- A simulation developed to detect iliopsoas impingement was validated for THA patients, and the current study aimed to validate it for HRA patients and compare differences in incidence between the two groups.
- The simulation proved effective, showing an 83% sensitivity and 100% specificity in predicting iliopsoas tendonitis in HRA patients, while also finding less impingement in the HRA cohort compared to the THA
Aims: Iliopsoas impingement occurs in 4% to 30% of patients after undergoing total hip arthroplasty (THA). Despite a relatively high incidence, there are few attempts at modelling impingement between the iliopsoas and acetabular component, and no attempts at modelling this in a representative cohort of subjects. The purpose of this study was to develop a novel computational model for quantifying the impingement between the iliopsoas and acetabular component and validate its utility in a case-controlled investigation.

The conventional technique for measuring LLD has historically been on a non-weightbearing anteroposterior pelvic radiograph; however, this does not capture many potential sources of LLD. The aim of this study was to determine if long-limb EOS radiology can provide a more reproducible and holistic measurement of LLD.

Previous assessments of femoral anteversion examined anatomic femoral anteversion (AFA) referenced to anatomic landmarks. However, this does not provide a functional understanding of the femur's relationship to the hip.

To improve patient outcomes and reduce costs in TKA, greater emphasis should be placed on the pre- and postoperative periods as, historically, innovation has focused on the intraoperative execution of the surgery. The purpose of this study was to determine if a pre- and postoperative physiotherapy program delivered via a digital application could reduce hospital length of stay (LOS) without compromising patient outcomes.
