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modular LDH THA, despite being discontinued, exhibited higher reliability and lower failure rate compared to similar withdrawn MoM implants.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: This study investigated the incidence of in-hospital complications in patients who underwent total hip arthroplasty (THA) and hip resurfacing arthroplasty (HRA). The results showed that patients who underwent HRA had fewer preoperative comorbidities, shorter hospital stays, and higher medical costs. However, HRA was associated with a higher risk of in-hospital prosthesis loosening. It is important for surgeons to pay more attention to in-hospital complications of HRA.

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: 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.

Summary: This systematic review and meta-analysis compared resurfacing hip arthroplasty (RHA) and total hip arthroplasty (THA) in terms of complications, revisions, functional outcomes, blood loss, operative time and metal ions levels. The findings showed that RHA had significantly lower blood loss but longer operative time compared to THA. There was no significant difference in complications, revisions, functional outcomes, and metal ion levels between RHA and THA. Both RHA and THA were found to be safe and effective, with RHA being a valid alternative to THA in young and active patients.

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 compared the failure causes and survivorship of metal-on-metal (MoM) resurfacing hip arthroplasty (RHA) and total hip arthroplasty (THA) over a minimum follow-up period of ten years. Results showed that RHA had significantly higher survivorship compared to THA, with THA having a higher rate of adverse reaction to metal debris failure. Ion levels and Co/Cr ratio were also significantly higher in THA.

Summary: This study evaluated the clinical outcomes of patients undergoing Birmingham hip resurfacing (BHR) and found that the 5-year patient-reported outcomes were comparable to patients undergoing direct anterior approach (DAA) or posterior approach (PA) total hip arthroplasty (THA). The BHR surgery showed good functional status and outcomes, which compared favorably with the control groups.

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 followed up 160 patients with primary large head MoM prostheses for 10 years. Results showed that female gender, cup inclination angles over 45 degrees, higher levels of cobalt, and chromium were associated with an increased risk of revision for ARMD. The safe upper limits for cobalt and chromium were determined to be 4.1 ppb and 4.2 ppb, respectively.

Summary: This study aimed to compare different bearing surfaces after cementless total hip arthroplasty. A network meta-analysis was conducted to assess 64 eligible trials. The findings showed that bearings containing highly cross-linked polyethylene (HXP), vitamin E-infused highly cross-linked polyethylene (HXPE), and ceramic liners demonstrated comparable survivorship and hip function at 5 and 10 years follow-up. Hard-on-hard bearings containing metal had higher serum levels of metal ions.
