Article Synopsis
- The study aimed to explore how different outcome measures (symmetry-based and performance-based) relate to each other in patients undergoing total hip arthroplasty (THA) due to end-stage hip osteoarthritis.
- It involved 24 patients assessed before surgery and at multiple points post-op using various functional tests, with improvements noted by the 10th week post-surgery.
- The results showed no strong correlations between the different types of measures, indicating that each measure provides unique information and highlighting the need for more clarity on the role of symmetry in evaluating function after THA.
Increasing grades of frontal deformities in knee osteoarthritis are not associated with ligamentous ankle instabilities.

Purpose: Varus or valgus deformities in knee osteoarthritis may have a crucial impact on ankle subtalar range of motion (ROM) and ligamentous stability. The purpose of this study was to assess whether the grade of ankle eversion and inversion rotation stability was influenced by frontal deformities of the knee joint.
Methods: Patients who were planned to undergo total knee arthroplasty (TKA) were prospectively included in this study.
The Recovery of Weight-Bearing Symmetry After Total Hip Arthroplasty Is Activity-Dependent.

Article Synopsis
- The study investigated how patients recovering from total hip arthroplasty (THA) regain weight-bearing symmetry (WBS) and ipsilateral loading during daily activities, using specialized insoles.
- Measurements were taken at four specific times in the THA group, allowing for a comparison to a control group, showing that significant improvements were noted primarily in standing comfortably and sit-to-stand-to-sit transitions.
- While THA patients reached similar levels of ipsilateral loading and WBS to healthy individuals by 6-12 weeks post-surgery, walking still showed some deficits, indicating the need for pre-operative assessments to fully capture individual recovery progress.
Overstretching Expectations May Endanger the Success of the "Millennium Surgery".

Total hip arthroplasty (THA) is an extremely successful treatment strategy. Patient expectations, however, have increased; if not properly guided by surgeons, at present, patients expect next to pain-free restoration of the joint and a fast return to work and sports. While the revision rates after THA also increased in younger patients, knowledge on musculoskeletal loads still remains sparse, and the current recommendations on postoperative rehabilitation are based on expert opinions only.

While there is much focus on the angulation of the joint line in static frontal radiographs, precise knowledge of the associated dynamic joint line orientation and the internal joint loading is limited. The aim of this study was to analyze how static alignment in frontal radiographs relates to dynamic alignment and load distribution, based on direct measurements of the internal joint loading and kinematics.
