Back to Healio

From implant technology and robotic surgery to techniques and complications, Healio revisits the most influential news, research and advancements in total hip arthroplasty in 2022.

Robotic-assisted THA provides more reliable cup positioning, stability vs. manual THA

Compared with manual THA, robotic-assisted THA produced more reliable cup positioning and offered superior protection against dislocation and revision. Read more.

Direct anterior THA linked with lowered risk of dislocation, revision

Compared with the posterior approach to THA, the direct anterior approach lowered the risk of dislocation and revision. Read more.

Diagnose, treat ‘easy-to-miss’ intraprosthetic dissociation in failed dual mobility THA

While dislocation and intraprosthetic dissociation rates in dual mobility THA are low, it is crucial to diagnose and treat these “easy-to-miss” presentations to avoid further surgery. Read more.

Changing surgical approach from primary to revision THA does not affect outcomes

Compared with concordant approaches, discordant surgical approaches between primary and revision THA have no impact on dislocation, re-revision, reoperation or complication rates. Read more.

Dual mobility vs. ‘jumbo’ femoral heads yield similar results for primary THA

With comparable outcomes to large diameter metal-on-metal femoral heads, dual mobility THA provides no benefit “beyond that of the large effective head size.” Read more.

Sex of surgeon shows no significant impact on 90-day adverse events of primary THA

Despite slightly lower odds of 90-day adverse events for THA procedures performed by female surgeons, results found no significant association between surgeon sex and risk of these events following THA. Read more.

Surgical planning, technique improve results of THA for developmental dysplasia of the hip

THA for patients with developmental dysplasia of the hip may yield promising results; however, careful planning and surgical techniques are required to improve survivorship and reduce complications. Read more.

Speaker: Osteolysis should still be considered for highly XLPE THA

Late osteolysis may still be a concern for patients undergoing THA with highly crosslinked polyethylene, despite notable reductions in wear and improved survivorship. Read more.
