Hip resurfacing arthroplasty as an alternative to total hip arthroplasty in patients aged under 40 years

..declared “HRA is an excellent bone preserving intervention carrying low complication rates, revision rates, and excellent patient outcomes without lifetime restrictions allowing these patients to return to activity and sport”.

The study identified 267 hips from 224 patients who underwent HRA from a single fellowship-trained surgeon using the direct lateral approach between 2007 and 2019. The mean age at operation was 33.4 years, including 23 females all of which were not revised.

Key Outcomes:

·        Average Harris Hip Score (HHS) was 100

·        No hip dislocations or fractures occurred

·        No patients had abnormally elevated metal ions

·        No adverse local tissue responses, or pseudotumors.

The author stated, “Our findings demonstrate HRA is a safe and reproducible procedure among high-volume surgeons that may potentially offer a tremendous advantage over THA in terms of quality of life for patients seeking to resolve their pain and disability of a destructed hip joint without sacrificing participation within a sport”.

JM Comments:

As the largest study for HRA patients under 40, this retrospective analysis is extremely encouraging for younger patients who follow an active lifestyle, and those who wish to maintain their existing lifestyle habits.
