Summary: Young women aged 15 to 45 who undergo total hip replacements have a higher risk of revision compared to those over 75 years old. 12% to 17% of women of childbearing age who have had a total hip replacement will later experience at least 1 pregnancy. Young women who have a total hip replacement do not have an increased risk of pregnancy complications. Among women who experienced pain with a total hip replacement during pregnancy, 60% still felt pain after delivery, with 21% experiencing persistent pain and 4% reporting severe pain. Limited studies suggest that women who have a total hip replacement and subsequently experience pregnancy and childbirth do not have an increased risk of pregnancy complications or revision rates.

Summary: This study analyzed the impact of the COVID-19 pandemic on total hip arthroplasty (THA) with cemented (CHP) and cementless (CLHP) prostheses, in terms of the benefit/cost ratio. The results showed that both CHP and CLHP THA procedures could reduce hospitalization duration during the COVID-19 period, with CHP offering better outcomes in terms of mobilization and shorter hospitalization duration compared to CLHP.

Summary: In this study, a fretting wear algorithm was developed to investigate wear damage on bearing surfaces of THRs, predicting linear and volumetric wear rates effectively. Results showed comparable wear rates to in-vivo THRs and matched wear patterns from conventional polyethylene liners, offering potential for reducing wear rates in THR design and clinical techniques.

Summary: This study compared the 10-year polyethylene wear rates between OxZi/XLPE and CoCr/XLPE articulations using radiostereometric analysis. The results showed no significant difference in steady-state wear rates between OxZi and CoCr, and both were below the threshold for osteolysis. The OxZi cohort demonstrated higher scores in the Harris Hip Score.

Summary: This study identified excessive wear and a potential risk of osteolysis associated with a uniquely designed moderately cross-linked polyethylene liner used in total hip arthroplasty.

Summary: The study found that preoperative templating for THA using EOS imaging is accurate, with good inter-observer agreement. EOS imaging is more likely to predict accurate acetabular and femoral component size compared to conventional radiographs. Demographic variables such as age, gender, laterality, or BMI do not influence component size and offset.

Summary: The study found that increased surgeon experience in performing THA in patients with severe obesity was associated with fewer major surgical complications, highlighting the importance of surgeon experience in reducing surgical risks.

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 study evaluated the clinical features and results of revision total hip arthroplasties in patients with catastrophic failures and metallosis. It was found that the mean Harris hip score increased by 20 points after revision THA, indicating improved clinical outcomes.

Summary: This study evaluated the impact of susceptibility artifacts from hip prostheses on cancer detection rate (CDR) in prostate MRI. The results showed that moderate to severe artifacts led to a decrease in CDR by 74%. This is clinically significant and may require expanding the indications for biopsy.

Summary: The study found that short-term mortality following THA/TKA increased with increasing frailty. Among surgical patients, mortality also increased with increasing frailty. In contrast, all-cause 30-day mortality following THA/TKA did not increase when comparing cases with controls in the same frailty category.

Summary: Congenital bladder exstrophy is a rare malformation often associated with pubic diastasis and hip dysplasia. This study reported two cases of patients undergoing total hip arthroplasty for advanced osteoarthritis combined with large congenital pubic diastasis, suggesting that THA may be an effective strategy for managing advanced hip osteoarthritis in patients with dysplasia and congenital pubic diastasis.

Summary: This study explored the surgical technique and clinical outcomes of cementless total hip arthroplasty combined with impacted bone grafting for the treatment of moderate and severe acetabular protrusion with rheumatoid arthritis. The results showed that this surgical method can reconstruct the acetabulum, restore the rotation center of the hip joint, and achieve good medium-term outcomes.

Summary: Mechanical ileus as a complication of total hip arthroplasty, caused by intrapelvic migration of the prosthetic femoral head, is rare but severe and should be recognized in clinical practice.
