Summary: This systematic review investigates the outcomes of total hip replacement (THR) using Modular dual-mobility (MDM) constructs. The study found a low incidence of ARMD, but mild elevation in serum metal ion levels in some cases. Additionally, the dislocation rate was 0.8%, and the revision rate was 3.3%. There are mixed reports regarding wear on the backside of the metal liner from the acetabular shell and screw heads.

Summary: This study compared the long-term outcomes of dual-mobility acetabular implants and conventional single-bearing implants in Kerboull-type reinforcement ring constructs for acetabular revision. The results showed that dual-mobility implants had equivalent survivorship and lower dislocation rates compared to single-bearing implants.

Summary: Revision THA using the MDM system was effective in treating recurrent dislocation in a group of patients with a high prevalence of lumbar spinal pathology. During a mean follow-up of 4 years, one additional revision THA was performed for septic loosening and none for aseptic loosening.

Summary: This study compared the use of constrained acetabular components and dual mobility implants in revision total hip arthroplasty (rTHA) and found that dual mobility implants had lower rates of dislocation, re-revision for dislocation, and re-revision for any cause compared to constrained acetabular components. Surgeons should consider these findings when choosing implants for the treatment of instability.

Summary: The study evaluated the inter-examiner repeatability of histopathologic grading methods in revision hip arthroplasty surgery, finding almost perfect inter-rater repeatability for individual factors and substantial agreement for the proposed major overall pattern. Correspondence analysis was able to identify individual features associated with the major pattern, facilitating evaluation of histopathologic tissue samples.

Summary: The use of cemented dual mobility cup (C-DMC) leads to a significant reduction in the risk of instability complications in total hip arthroplasty. A systematic review of 56 studies involving 3452 C-DMC patients showed an overall dislocation rate of 2.9% and good clinical outcomes.

Summary: The study compared and quantified kinematic parameters between DM THA and conventional THA, finding that DM THA had increased provocative subluxation range of motion and larger dislocation distances, which may contribute to its reduced dislocation rates and increased stability in at-risk hip positions.

Summary: The use of dual mobility cups in total hip arthroplasty has become popular due to their ability to reduce dislocation risk. This study calculates the jumping distance for different modular dual mobility cup systems and provides a systematic literature review of their clinical outcomes and failure reasons.

Summary: This study found that there is no significant difference in revision rates for dislocation or aseptic causes between dual mobility and large femoral heads in primary total hip arthroplasty. When stratified by acetabular component size, dual mobility can reduce dislocation for acetabular component diameter <58 mm.

Summary: The study evaluated the outcomes of using MDM components in revision THA with a mean follow-up of over five years. It found a higher rate of dislocation than previously reported, with the size of the outer bearing being related to the risk of dislocation. There was a low rate of aseptic acetabular loosening observed in the study. Further research and longer follow-up are needed to assess the performance of this MDM component and other designs.

Summary: The study found that DMC-DAA-THA for displaced FNF resulted in no dislocation within one year postoperative, low mortality rate, and quick recovery of walking ability. The combination of the minimal invasiveness of DAA, increased range of motion by DMC, and adequate soft tissue tension by DAA contributed to reduced dislocation and improved recovery of walking ability.

Summary: The study found that using dual mobility cups in well-fixed cups for total hip arthroplasty is a promising short- to mid-term treatment, especially for elderly and frail patients. Reduced operation time is one of the advantages of this technique; proper cementation technique, adequate cup positioning, and selection of a sufficiently large dual mobility cup are crucial for treatment success. Longer follow-ups will be needed in the future to further prove the benefits of this technique.

Summary: This study evaluated the implant survivorship, complications, and clinical outcomes of primary total knee arthroplasty (TKA) performed in patients with metabolic syndrome (MetS). The results showed that MetS did not significantly increase the risk of reoperation after TKA, but MetS patients with a BMI >40 had a two-fold increased risk of revision and reoperation for periprosthetic joint infection (PJI).

Summary: This study developed a machine learning algorithm to predict factors contributing to unexpected hospitalizations after ambulatory unicompartmental knee arthroplasty (UKA). The algorithm outperformed conventional logistic regression models and can help identify patients at a higher risk of needing inpatient care after UKA.

Summary: This study investigated the effect of femoral head length on the risk of revision and reoperation after cobalt chromium-on-highly crosslinked polyethylene THAs. The results showed that altering the femoral head length did not have a significant effect on outcomes, and surgeons should consider other factors such as hip stability and center of rotation when selecting femoral head lengths.

Summary: This study assessed the correlation between pelvic-spine distance (PSCD) and lateral lumbar radiographic metrics in a cohort of preoperative total hip arthroplasty (THA) patients. The results showed a weak correlation between pelvic and lumbar measurements. Therefore, PSCD cannot be reliably used as a proxy for evaluating the hip-spine relationship.

Summary: This study aimed to describe the survivorship, complications, radiographic results, and clinical outcomes of total knee arthroplasty (TKA) after anterior cruciate ligament (ACL) reconstruction. The study found that the survivorship of TKA after ACL reconstruction was lower than expected, with instability being the most common reason for revision. Additionally, the most common nonrevision complications were flexion instability and stiffness requiring manipulations under anesthesia, indicating the difficulty in achieving soft tissue balance in these knees.

Summary: This study investigated the effect of oral medications on preventing arthrofibrosis and manipulation under anesthesia following total knee arthroplasty. The results showed that perioperative use of NSAIDs was associated with a reduced risk of arthrofibrosis, and perioperative use of oral corticosteroids was associated with a reduced risk of manipulation under anesthesia.

Summary: Based on a cadaveric radiographic study, it was found that the flush rim design of modular dual-mobility liners can accurately detect malseating in 95% of cases, while the elevated rim design is more difficult to identify malseating on plain radiographs.

Summary: This study compared the effects of spinal anesthesia and general anesthesia in revision total knee arthroplasties. The results showed that patients who received spinal anesthesia had lower postoperative pain, shorter length of stay, and fewer complications compared to those who received general anesthesia. Spinal anesthesia was associated with reduced opioid requirements, decreased cases of altered mental status and intensive care unit admissions, and fewer re-revisions and reoperations.

Summary: Most data on irrigation and debridement with component retention (IDCR) as a treatment for acute periprosthetic joint infections (PJIs) focuses on primary total joint arthroplasties (TJAs). However, the incidence of PJI is greater after revisions. We investigated the outcomes of IDCR with suppressive antibiotic therapy (SAT) following aseptic revision TJAs.

Summary: This study analyzed the outcomes of primary total hip arthroplasty (THA) in dialysis-dependent patients. The results showed a high 5-year mortality rate but a low cumulative incidence of revision or reoperation. Renal metrics remained consistent after the surgery, but only a quarter of the patients successfully received a renal transplant.

Summary: This study investigated the impact of three different tibial designs on total knee arthroplasties (TKAs). The results showed that cementless and hybrid monoblock tibial components had better implant survivorship compared to the traditional modular cemented tibia. At 10-year follow-up, the traditional modular cemented tibia had a higher incidence of aseptic tibial loosening, while the other two groups did not. Clinical outcomes were similar and excellent in all three groups.
