Hip resurfacing arthroplasty reduces dislocation and infection rates...

In a recent network meta-analysis, “Hip resurfacing arthroplasty reduces dislocation and infection rates without differences in clinical outcomes compared to short and standard stems: A Network Meta-Analysis,” Riche et al. (2025) stated, “HRA demonstrated had lower infection and dislocation rates compared to standard THA.”

The meta-analysis compared three hip arthroplasty techniques—Hip Resurfacing Arthroplasty (HRA), Short-Stem Total Hip Arthroplasty (THA), and Standard-Stem THA—with a focus on complication rates, clinical outcomes, and surgical factors. Analysing 72 studies involving 793,593 patients, the study provides comprehensive comparative data across a range of outcome measures.

Key Outcomes:

• Dislocation: HRA had a lower dislocation rate than standard-stem THA

• Infection: HRA also showed lower infection rates than standard-stem THA

• Operative Time: HRA had the shortest operative time compared to both short- and standard-stem THA.

JM Comments:

These findings reinforce JointMedica’s ongoing support of HRA as a viable, lower-risk alternative to conventional THA, especially for active and younger patient populations. Also, with a shorter operative time, HRA can be seen to offer increased operating room efficiency and resource optimisation.
