A 2026 review compared the main ways surgeons reach the hip during a replacement. The front (anterior) approach may speed early recovery, but by a year the approaches even out — and the surgeon's experience matters more than the route.
If you are researching hip replacement, you will quickly meet a debate about the approach — the direction from which the surgeon reaches the hip joint. The main options are the posterior (from the back), direct lateral (from the side) and direct anterior (from the front). Some clinics market one approach heavily, so it is fair to ask: does it actually change how you do?
What the study looked at
The researchers gathered comparative studies published between 2015 and 2025 that put at least two of these approaches head to head and followed patients for at least a year. They looked at how quickly people recovered, pain in the early weeks, the risk of the hip dislocating, nerve problems, muscle weakness around the hip, and what happens when a replacement later needs redoing (revision surgery).
What they found
Rather than combining everything into a single number, the review summarised the patterns across studies:
The anterior (front) approach tended to give a quicker early recovery, a little less pain in the first weeks, and a lower chance of dislocation.
The direct lateral (side) approach was more often linked to temporary weakness of the hip muscles, which usually settles.
Nerve-related niggles differed depending on the approach used.
By around a year, the approaches were broadly equal in how well people were doing.
For revision (redo) surgery, the posterior approach remained the preferred route.
What it means for you
The approach is one piece of the picture, not the whole picture. On this evidence, an anterior approach may get you moving a little sooner, but the differences between approaches tend to fade within the first year, and every major approach can achieve an excellent long-term result. What matters at least as much is the experience of your surgeon with the approach they use, and how well the approach suits your particular hip and body. It is worth discussing — but not a decision to make on marketing alone.
A caveat worth knowing
This was a narrative review: it described the trends across studies rather than pooling them into precise figures, so it cannot put an exact number on any difference. Most of the underlying studies were observational, which makes it hard to fully separate the approach from the surgeon using it. The sensible takeaway is about setting expectations, not ranking the approaches — a starting point for a conversation about your own operation.
Assessing this studyA standardised appraisal for clinicians and registrars — study design, strength and validity.+
Study design
Systematic review (PRISMA) of comparative studies published 2015–2025 that compared at least two hip-replacement approaches; a narrative synthesis, not a meta-analysis.
Level of evidence
OCEBM Level 3 (therapy) — a systematic review of mostly non-randomised comparative studies, with no pooled meta-analysis.
Are the results valid?
A pre-specified PRISMA search across PubMed, Scopus and Web of Science was restricted to studies with at least 12 months of follow-up that compared two or more approaches. The underlying studies are largely observational, so surgeon experience and case selection (confounding by indication) can bias approach-versus-approach comparisons. Findings were summarised narratively rather than pooled, and the review does not report a single effect size or confidence interval.
What are the results?
Qualitatively, the direct anterior approach was associated with faster early functional recovery, less short-term pain and lower dislocation rates; the direct lateral approach carried more transient abductor (hip-muscle) weakness; and nerve-related complications were approach-specific. Long-term outcomes were equivalent across approaches, and the posterior approach remained preferred for revision surgery. No pooled numeric estimates were provided.
Do they apply to our patients?
Directly relevant to counselling patients weighing an "anterior versus posterior" hip replacement. Because the results are not pooled and lean on mostly observational data heavily influenced by surgeon experience, it supports general expectation-setting rather than any claim that one approach is superior.
Bottom line
Reasonable evidence that all the main hip-replacement approaches do well in the long term; the anterior approach may give a faster early recovery, but the review does not establish one approach as best, and surgeon experience appears to matter more than the route taken.
