Background: In recent years, there has been an increase in the number of total hip arthroplasty procedures in the younger patient population. This active group has higher expectations of their prosthesis in comparison to the older population, and there is a greater physical demand for the prosthesis. Short femoral stems were introduced to retain proximal bone stock and joint biomechanics and became more common to implant in this specific population.

- Current research on managing the hip capsule after hip arthroscopy shows no significant difference in outcomes between capsular repair and unrepaired capsulotomy, as measured by patient-reported outcomes.
- A study evaluated 28 patients using MRI to assess capsular integrity, revealing fewer defects in the repaired group (2) compared to the unrepaired group (7), but these differences were not statistically significant.
- The findings suggest that while capsular defects were affected by the presence of a labral repair and the lateral center-edge angle, overall, the type of capsular management (repair vs. unrepaired) did not yield substantial differences in defect rates.
Article Synopsis
- The study examines how well femoroacetabular offset (FAO) is restored using either short or conventional hip stems during total hip arthroplasty, emphasizing the importance of restoring anatomy to improve post-surgery function.
- It uses digital templating on 100 hip radiographs to classify restoration success based on whether the FAO difference from baseline is less than or equal to 5 mm.
- Findings will help determine the effectiveness of short stems in restoring anatomy and assess the reliability of these measurements involving multiple observers.
Total hip arthroplasty is performed more frequently in younger patients nowadays, making long-term bone stock preservation an important topic. A mechanism for late implant failure is periprosthetic bone loss, caused by stress shielding around the hip stem due to different load distribution. Short stems are designed to keep the physical loading in the proximal part of the femur to reduce stress shielding.
View Article and Find Full Text PDFTrial fitting of the cup during total hip arthroplasty (THA) is done by trial cups, which do not resemble the real press-fit obtained by the definitive implant. Our goal is to judge feasibility of the X-pander® in clinical practice ; a device developed to mimic the real press-fit obtained by the definitive cup, to ensure satisfactory press-fit. In this feasibility study 45 experienced orthopaedic surgeons from 7 European countries filled in a structured survey after 78 primary THA and 31 revision surgeries, using the X-pander instead of traditional trial cups.
View Article and Find Full Text PDFBackground: Hip capsular management after hip arthroscopy remains a topic of debate. Most available current literature is of poor quality and are retrospective or cohort studies. As of today, no clear consensus exists on capsular management after hip arthroscopy.
View Article and Find Full Text PDFBackground And Purpose: The consensus that bone stock preservation and optimal restoration of offset and leg length is important in total hip arthroplasty is now widespread, especially for young and active patients. Short stems seem promising in this aspect, though implant stability is still of concern. This study looked at the migration pattern of the Optimys short stem through RSA analysis.
