Summary: Polymer wear debris is a major concern in total joint replacements due to potential biological reactions. This study proposes an automatic particle segmentation algorithm using adaptive thresholding and Convolution Neural Network (CNN) classification. The use of computer algorithms and CNN allows for more efficient analysis of wear debris with complex characteristics, resulting in robust size and volume distribution graphs for estimation.

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: 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: 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 evaluated the tribological acceptability of reducing the acetabular liner thickness in metal-on-vitamin-E diffused highly crosslinked ultra-high molecular weight polyethylene (Vit-E XLPE) bearings for total hip arthroplasty. The results showed that reducing the thickness by 2-4 mm did not significantly affect the wear rate of the Vit-E XLPE liner, but reducing it by 6 mm significantly increased the wear and roughness.

Summary: The wear resistance of UHMWPE can be improved by adjusting the thermal history and utilizing γ-ray irradiation. The crystallinity of UHMWPE significantly affects the wear resistance, and high crystallinity crosslinking is more effective. These findings have important implications for developing high-performance artificial joint prosthesis materials.

Summary: This study aims to investigate the wear amount and rate in patients with second-generation XLPE bearing in THAs surgery during the first 10 years, and explore whether the wear rate changes after 5 years in situ. The results showed that femoral head penetration in second-generation XLPE liner remained very low at 10 years and accelerated wear did not occur after 5 years in situ. These findings provide encouraging evidence for the future clinical performance of this material.

Summary: The use of vitamin E-blended ultra-high molecular weight polyethylene (VE-UHMWPE) in prosthetic components of hip implants improves mechanical properties and reduces adverse cellular responses. Through in vitro and in vivo experiments, we found that a 0.3% concentration of vitamin E is the most suitable for prosthetic components, as it reduces adverse cellular responses and extends the lifespan of the implant.

Summary: The study showed that HXLPE significantly outperformed CPE in preventing revision surgery and radiological osteolysis in total hip arthroplasty. It also demonstrated lower polyethylene wear rates and head penetration rates in the HXLPE group compared to the CPE group. However, no significant differences were observed in functional outcomes between the two groups.

Summary: The combination of cemented Spectron EF stem and cemented non-crosslinked Reflection All-Poly cup has a high rate of mid-term aseptic loosening. The study assessed tissue reactions, wear particles, and blood metal ion levels in patients with failed implants. The results showed a significant presence of inflammatory cells and wear particles, with severe stem abrasion. These factors contribute to osteolysis and implant loosening.

Summary: Particle-induced osteolysis is a major cause of prosthetic loosening. In this study, the influence of fetuin-A on particle-induced osteolysis was investigated using fetuin-A-deficient mice. The results showed that fetuin-A deficiency led to increased bone resorption, eroded surface areas, and osteoclast numbers. Fetuin-A deficiency also caused changes in bone metabolism parameters. These findings suggest that fetuin-A deficiency may be a risk factor for particle-induced osteolysis.

Summary: The aim of this study was to compare the efficacy of highly crosslinked polyethylene (HXLPE) and conventional polyethylene (CPE) in total knee arthroplasty (TKA). The results showed no statistically significant differences between HXLPE and CPE in terms of clinical, radiological, and functional outcomes. Therefore, HXLPE can be safely used for TKA.

Summary: This study reveals the significant role of caspase-1-dependent pyroptosis in osteocytes in facilitating osteoclastic osteolysis induced by UHMWPE particles. Furthermore, it is found that DFO alleviates UHMWPE particle-induced osteoclastic osteolysis partly by inhibiting pyroptosis in osteocytes.
