Changes in femoral offset is not associated with increased incidence of lateral hip pain following total hip arthroplasty.
Article in Journal of clinical orthopaedics and trauma, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIncreased femoral offset following total hip arthroplasty allows for greater stability of the hip joint. However, the increase in femoral offset can cause an impingement of local structures resulting in persistent lateral hip pain. There is conflicting evidence whether changes in femoral offset increases the rates of lateral hip pain following total hip arthroplasty.
methodsThis was a retrospective case control study that grouped patients based on the presence of persistent lateral hip pain following total hip arthroplasty. Patients were then stratified according to their change in femoral offset (<-5 mm, -5 mm < x < 5 mm, and 5 mm<). A chi squared analysis was then performed to see if there was a statistical difference in the rates of lateral hip pain amongst these groups.
resultsA change in femoral offset of the implanted hip relative to the native hip was not associated with increased rates of lateral hip pain following total hip arthroplasty (p = 0.35). A change in femoral offset of the implanted hip relative to the contralateral hip was not associated with increased rates of lateral hip pain following total hip arthroplasty (p = 0.40).
conclusionThis study found that there was no association between increased femoral offset and rates of postoperative lateral hip pain following total hip arthroplasty. Future investigations should look at a larger sample size with multiple institutions to further assess the impact on femoral offset changes on rates of persistent lateral hip pain.
