Background. Problems encountered during revision hip arthroplasty are presented, based on 30 years of experience at the Orthopedic Clinic of the Medical University of Lodz.
Material and methods. During this period of time 96 cases (5,13%) with aseptic hip loosening were diagnosed. All patients were evaluated clinically based o the Merle d'Aubigne-Postel criteria, and radiologically by means of De Lee and Gruen migration zones.
Results. In our material hip loosening was most frequently observed in cases where a McKee-Farrar hip prosthesis had been used, and in cases with a PM uncemented acetabulum or uncemented Mittelmeier pin.
Conclusions. The study showed that surgical technique plays the most significant role in aseptic loosening of hip replacement. The aseptic loosening of hip prostheses should be diagnosed early, and revision hip arthroplasty should be performed as soon as possible. This surgery must be preformed in specialized centers with adequate equipment and a team of experienced surgeons.

Background: Endogenous sex hormones in postmenopausal women have been associated with risk of cardiovascular diseases. The aim of this study was to determine the association between endogenous sex hormones and the revised Framingham Stroke Risk Profile (rFSRP) in postmenopausal women.
Methods: This is an observational cross-sectional study on the Vara-Skövde cohort, a Swedish population-based study for longitudinal surveillance of the development and progress of type 2 diabetes and hypertension.

Background: The risk of early revision of total hip arthroplasty (THA) for polyethylene wear is now low, but there remains a need to perform wear measurements in patients for clinical surveillance. The gold standard of wear measurements has been radiostereometric analysis (RSA), which has limited availability. The use of computed tomography (CT) to perform THA wear measurement was described a decade ago and found to have acceptable accuracy and precision, but high radiation dose was a concern.

Pseudotumors are defined as exuberant non-neoplastic inflammatory masses. This condition can be associated with hip and knee arthroplasty but has not been reported in Total Ankle Arthroplasty (TAA). This paper reports a pseudotumor that formed following TAA, highlighting its clinical presentation, management, and histopathology.

Managing periprosthetic femoral fractures is challenging, particularly in osteoporotic patients with fragile bones. Revision with a long stem is commonly considered but may fail to provide adequate fixation and stability in fragile bones. A novel approach using sandwiched strut allografts and controlled bone crushing with robust cable fixation can offer mechanical support and provide secondary stability to the loosened femoral stem and can be considered a treatment option for low-demand patients.

Purpose: The outcome of elective total joint arthroplasty (TJA) in patients with Parkinson's disease (PD) is controversial due to the concomitant risk profile. This study investigated postoperative complications and revision rates following total hip (THA) and knee arthroplasty (TKA) in patients with PD.
Methods: Ninety-six patients with PD undergoing THA or TKA were matched 1:1 with non-PD patients using propensity score matching for age, sex and comorbidity (Charlson Comorbidity index, CCI).
