Summary: This study aimed to determine if hip movement precautions reduce the risk of dislocation after hip arthroplasty using a posterior surgical approach. The meta-analysis of multiple studies found that there was no increased risk of dislocation in the group with minimal or no movement restrictions compared to the group with hip movement precautions. Therefore, allocating resources to implementing hip movement precautions may not be necessary.

Summary: The purpose of this study was to compare the clinical and radiographic outcomes of three different stem designs for subtrochanteric osteotomy in Crowe IV DDH. The results showed that although Ribbed, Synergy, and LCU stems have similar clinical outcomes, the LCU stem had issues such as stem loosening, longer union time, and a tendency to varus position. Therefore, the use of LCU stem is not recommended in this situation.

Summary: The study found that nonagenarians undergoing elective total hip arthroplasty (THA) had higher morbidity and mortality rates, with major risk factors including congestive heart failure, pulmonary circulation disorders, insulin-dependent diabetes, among others. However, careful patient selection and adequate preparation can help control mortality rates, as shown by the fact that mortality rates in nonagenarians were lower than in the general population.

Summary: In cases where mobility and joint function are impaired after implantation of a THA, weakening of hip movement in both extension/flexion and adduction/abduction may play a role due to shortening of the physiological lever arm of the hip muscles. Mechanical factors of influence include the lateral femoral offset, which affects the lever arm, and the antetorsion angle of the hip prosthesis, which affects the anterior femoral offset. This study aimed to investigate the effect of an altered antetorsion angle of the implant on the hip moments and gait patterns of the patient. The results showed that joint function measured by isokinetic measurements and gait analysis remains comparable to the healthy control group after short stem arthroplasty, but shows slight changes after conventional stem arthroplasty.

Summary: This study compared hip and knee arthroplasty outcomes between a District Hospital (DH) and a Tertiary Academic Hospital (TH) in Cape Town, South Africa. The results showed that surgeries performed at the district level had shorter hospital stays, lower readmission rates, lower reoperation rates, and relatively lower mortality rates. Therefore, arthroplasty at the district healthcare level is safe and may help alleviate the pressure on arthroplasty services at tertiary care facilities.

Summary: In a qualitative study, patients who had undergone total hip or knee replacements were asked to define what constitutes a failure of total joint replacement. The highest ranked responses included refractory joint pain, postoperative adverse events, inability to resume normal activities, and lack of improvement in quality of life. The study found that functional failure was as important as, or even more important than, surgical failure in defining TJR failure.

Summary: This study developed and validated bi-directional crosswalks between the Oxford Hip Score (OHS) and HOOS-12 summary impact score, and between the Oxford Knee Score (OKS) and KOOS-12 summary impact score. The results showed high correlation and concordance between actual scores and crosswalk-derived scores, suggesting that these crosswalks can be used for PROMs score conversion and data harmonisation efforts in clinical practice, research, and joint replacement registries.

Summary: Hip arthroplasty procedures have high success and reproducibility. However, hip dislocations are the most common cause for revisions within the first two years post-surgery, despite the majority of the dislocations occurring within the 'safe zone' of the acetabular component. The limitations of this boundary neglect the variability of individual hip anatomy and functional pelvic orientation. To address hip instability and enhance outcomes, the alternative concept of functional acetabular orientation is discussed, including the kinematic alignment technique and the use of large-diameter heads in preventing total hip arthroplasty dislocations.

Summary: Controversy exists over the treatment of displaced lateral malleolar fractures without medial or syndesmotic injuries. While conservative treatment was common in the past, surgical intervention is now preferred by many patients for faster recovery. Surgical treatment offers benefits such as early ankle mobilization and biomechanical restoration, but can also lead to postoperative complications.

Summary: This study used weight-bearing CT to compare variables between the HR group and the control group. The HR group showed a significantly elevated first metatarsal and MPE greater than 4.19 mm was found to be diagnostic for HR. A significant number of patients in the HR group had dorsal translation of the first metatarsal at the first TMT joint, which may contribute to increased MPE.

Summary: This study investigated the relationship between genetic polymorphism of matrix metalloproteinases 1 and 13 and post-traumatic elbow stiffness, as well as the influence of other risk factors on this condition. The results showed no significant differences in the genotypes and alleles of MMP-1 and MMP-13 between patients and controls. Among the prognostic factors for elbow stiffness, only immobilization time showed a positive correlation.

Summary: The study evaluated the ability of Foot and Ankle Offset (FAO) in predicting the need for additional realignment procedures during total ankle replacement (TAR). The results showed a positive correlation between preoperative FAO values and the number of performed realignment procedures, particularly in patients with valgus malalignment. This suggests that biometric tools like FAO can improve preoperative assessment and surgical planning in TAR, potentially leading to better surgical outcomes.

Summary: Ankle osteoarthritis is a less common but equally disabling joint condition that greatly impacts patients' quality of life. Conservative treatment, medication, and surgery are all viable options for managing this disease. Periarticular osteotomies are recommended in the early stages, while ankle arthrodesis and replacement can provide satisfactory outcomes in the late stages.

Summary: The aim of this study was to analyze the morphology of the lateral malleolus and propose a treatment algorithm based on its shape for IM fixation of fibular fractures. CT scans of the ankle were performed on 77 healthy volunteers, and the fibular medullary canal and cortical thickness were analyzed at different levels. A geometric classification and decision algorithm were developed. The results showed that the shape of the distal fibula allows for IM osteosynthesis in 83% of individuals. The smallest diameter of the fibular medullary canal was located 6.0 cm from the tip of the lateral malleolus. Coronal CT evaluation can help determine the appropriate IM implant for infra- and transsyndesmotic fracture patterns.
