Summary: Periprosthetic osteolysis is a common complication of joint replacement surgery, caused by wear-induced particulate debris. Advances in understanding the mechanism of osteolysis and developing strategies for prevention and treatment are being made. Therapeutic agents targeting proinflammatory mediators have shown promise, but the delay in diagnosis and treatment remains challenging.

Summary: This study aimed to determine the minimum 20-year survival rates of a cementless press-fit cup in young patients. The results showed that the 22-year survival rate for aseptic cup or inlay revision was 94%, and the survival rate for aseptic cup loosening was 99%.

Summary: The majority of canceled surgeries are due to medical reasons, with most patients eventually undergoing the procedure, but only a minority receiving intervention for their condition. Patients canceled for medical reasons tend to have higher Charlson Comorbidity Index, closer cancellation to the scheduled date, and are more likely to eventually undergo surgery.

Summary: This study investigates the factors affecting joint friction and temperature increase in patients with THA through a combination of in vivo and in silico technologies. The results highlight the significance of implant orientation, joint kinematics, and friction-induced temperature increase, emphasizing the importance of cup placement during surgery.

Summary: This study analyzed the early outcomes of aseptic revision TKAs using a specific implant system that was recently recalled. The results showed that when components from the same manufacturer were utilized, the survivorship free from rerevision was lower than expected. However, when both the components were revised with an alternative implant system, the survivorship was comparable to contemporary reports. Cone and sleeve metaphyseal fixation as well as highly constrained implants were frequently used during rerevision TKAs.

Summary: This systematic meta-analysis compares the long-term efficacy of highly cross-linked polyethylene (HXLPE) and conventional polyethylene (CPE) in preventing radiological osteolysis and revision surgery. The results demonstrate that HXLPE dramatically reduces the rate of osteolysis and wear-related revision surgery.

Summary: The study showed that patients who opted-in to web-based portals were younger, had higher BMI, and higher household income. Opting-in for TKA patients was associated with significant improvement in physical and joint-specific function, while for THA patients, increased portal logins were linked to faster improvement and higher functional scores.

Summary: THA implant characteristics do not directly affect inadequate improvement in pain and function, surgeons should choose implants with a stable track record and restore hip biomechanics.

Summary: In long-term follow-up of well-functioning implants for posterior stabilized and cruciate retaining knee designs, differences in kinematics and wear resistance were observed. Implant design was found to influence long-term kinematics and wear in well-functioning implants, with condylar separation linked to increased wear rates and should be avoided.

Summary: This study compared the revision rates of primary stemmed anatomic total shoulder arthroplasty using crosslinked polyethylene (XLPE) and non-XLPE. The results showed that non-XLPE had a higher risk of revision than XLPE, particularly for larger head sizes. The study suggests that the type of polyethylene is an important determinant of revision risk in shoulder arthroplasty.

Summary: This study assessed the impacts of surgical, patient, and implant design factors on tray-bone interface micromotions during cementless total knee arthroplasty. The results showed that careful surgical technique, patient selection, and joint design can effectively minimize micromotion.

Summary: The study demonstrates that optimizing surgical trays can significantly improve operating room efficiency and reduce costs in total joint arthroplasty. Using Lean methodology to eliminate redundant or underutilized instruments resulted in substantial annual cost savings of $281,298.05.

Summary: This study evaluated the differences in ankle force, motion, contact stress, and bone-implant interface micromotion among different ankle implant designs during physiological walking gait. The anatomical ankle implant design showed superior performance in recovering ankle joint motion, reducing contact stress, and minimizing bone-implant interface micromotion compared to other designs. Additionally, the fixation design of INFINITY resulted in lower bone-implant interface micromotion than INBONE II.

Summary: This study focused on analyzing emergency department (ED) visits within 30 days of elective, primary total hip or knee arthroplasty (THA and TKA) surgery, finding that 9.2% of patients presented to the ED during this time period. The most common reasons for ED visits were wound concerns and pain. Older age and preoperative dyspnea were identified as risk factors for ED visits, with after-hours visits incurring significantly higher costs.
