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 literature review aimed to evaluate the clinical performance and material changes of antioxidant stabilized highly cross-linked polyethylene (AO-XLPE) in total knee arthroplasty (TKA). The study found that AO-XLPE exhibited similar clinical outcomes as conventional materials, with excellent resistance to oxidation and surface damage, and no cases of osteolysis or revision due to polyethylene wear.

Summary: The study evaluated the use of HXLPE supplemented with DG as tibial inserts in TKA, showing promising wear resistance and characteristics of wear particles. HXLPE-DG demonstrated advantages over commonly used materials and potential application in TKA.

Summary: Studies have shown that total hip arthroplasty (THA) using highly cross-linked polyethylene (HXLPE) has favorable outcomes in the mid-to-long term for patients of all ages. Concerns about long-term failure and wear-related complications remain for young THA patients. However, research has found that wear-related revisions are low for patients under the age of 55, and factors such as higher activity levels, larger femoral head size, and femoral head material do not affect long-term wear rates. Young THA patients who have undergone the procedure with metal or ceramic on HXLPE have shown excellent durability and favorable outcomes in follow-ups of over 15 years.

Summary: This study aimed to investigate whether using a thicker liner in vitamin-E-diffused HXLPE could enhance in vivo creep and wear performance. The 7-year follow-up results showed no significant difference in wear rates between different liner thicknesses, but the thinner liner had higher strain. Further long-term follow-up is needed to evaluate the incidence of wear and osteolysis.

Summary: This study evaluates the clinical survivorship of two contemporary cementless total knee arthroplasty (TKA) designs with minimum 2-year follow-up. The results demonstrate encouraging survivorship of cementless fixation in primary TKA with the use of modern implant designs and biomaterials.

Summary: This study evaluated the long-term performance of second-generation HXLPE in total hip arthroplasty. The results showed low linear and volumetric wear rates for HXLPE, and younger age and higher body mass index were found to influence long-term wear. These findings suggest that second-generation HXLPE can be a suitable material for long-term total hip arthroplasty interfaces.

Summary: The objective of this study was to verify the safety and assess the reliability of a novel multiplanar arthrometer. The results showed high intraexaminer and interexaminer reliability in various directions of knee stability, and the device could be used to evaluate the relationship between laxity and patient perceptions of knee instability.

Summary: Research on the reaction of Bionate 80A implanted in the lumbar epidural space of rabbits found that the material does not generate a significant reaction in the surrounding soft tissues, and does not cross the dura mater or migrate to lymph nodes or organs.

Summary: The study found that the wear of monobloc PE inlay in total knee arthroplasty (TKA) is approximately 40% less than that of modular PE inlay at mid-term follow-up, indicating that back-side wear of modular PE inlays is a significant contributor to PE wear in hybrid TKA.

Summary: The study analyzed the effects of BCR-TKA on knee kinematics and cruciate ligament forces, finding significant changes in knee kinematics postoperatively that correlated with changes in cruciate ligament forces.

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: Conventional polyethylene (CPE) bearings used in total hip arthroplasty (THA) can experience wear-related issues after long-term use, especially in younger and more active patients. The long-term wear and survivorship data from this study serve as a benchmark for evaluating the performance of contemporary bearings in young and active THA patients.
