Summary: This study evaluated the accuracy of ultrasonography in detecting postoperative complications in HRA patients using a screening protocol that targets periprosthetic muscles. The results showed that ultrasonography can detect postoperative complications in HRA patients as effectively as MRI, with superior visibility in periprosthetic muscles compared to MRI.

Summary: This study evaluated the clinical and radiographic outcomes of patients undergoing primary cementless ceramic-on-ceramic total hip arthroplasty (THA) with a minimum follow-up of 20 years. The long-term follow-up showed excellent implant survival, excellent functional outcomes, and minimal late complications, with no significant radiographic evidence of failure at a minimum of 20 years after THA.

Summary: This study compared infection occurrence between Metal-on-polyethylene (MoP) and ceramic-on-polyethylene (CoP) total hip arthroplasty implants. It found a higher risk of periprosthetic joint infection in MoP patients, even after adjusting for confounders, indicating a significant association. The recruitment of leukocytes to these implants may play a role and warrants further investigation.

Summary: Total hip arthroplasty is a popular and effective surgical intervention for treating hip diseases. The success of the surgery depends on factors such as patient characteristics, surgical technique, and the quality of biomaterials used. Recent studies have assessed the benefits and drawbacks of different biomaterial and friction couples in total hip arthroplasty.

Summary: This long-term follow-up study found a relationship between polyethylene wear and pseudotumor formation in total hip arthroplasty (THA). The wear rate of polyethylene was significantly higher in the pseudotumor group compared to the non-pseudotumor group, potentially leading to the development of both pseudotumor and osteolysis. Further research is needed to understand the direct relationship between polyethylene wear and pseudotumor, as well as the mutual effects of osteolysis and pseudotumor in particle reactions.

Summary: This study aims to provide an updated analysis of the long-term outcomes and metal ion levels of patients with metal-on-metal hip resurfacing (HR) and large-diameter-head (LDH) total hip arthroplasty (THA). The results showed no significant differences in clinical outcomes between the two groups, but the HR group had significantly lower metal ion levels compared with the modular THA group. Both implants demonstrated excellent survivorship, with the Adept HR showing remarkable reliability in young active males. The modular LDH THA, despite being discontinued, exhibited higher reliability and lower failure rate compared to similar withdrawn MoM implants.

Summary: Studies have shown increased cancer risk among patients undergoing total hip arthroplasty (THA) compared to the general population. However, the evidence of cancer risk associated with different bearing surfaces remains inconclusive. This study found that the incidence of cancer significantly increased in patients undergoing THA for osteoarthritis compared to the Australian population.

Summary: The study aimed to compare gait function in female patients undergoing ceramic hip resurfacing arthroplasty (cHRA) and total hip arthroplasty (THA). The results showed that compared to THA, cHRA patients had higher MET scores and maximum walking speed, as well as more symmetrical gait and longer step length. The study suggests that cHRA allows female patients to regain gait function and activity levels similar to healthy individuals.

Summary: This study retrospectively investigated the long-term outcomes of total hip arthroplasty using highly cross-linked polyethylene (HXLPE) with alumina ceramic bearings. The results showed excellent wear properties, patient-reported outcomes, and acceptable survivorships at an average 16-year follow-up.

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: The study compared the outcomes of metal-on-metal large-diameter-head total hip arthroplasty and metal-on-metal hip resurfacing at 5-year follow up, finding no significant differences in Harris Hip Score and SF-36 scores between the two groups, both showing excellent results.
