Does the anterior approach to hip replacement speed recovery?
Short answerIn trials, recovery in the first weeks was a little faster with the anterior approach. The differences that reached statistical significance were early ones.

What it is
A surgeon can reach the hip joint from the front, the back or the side. The anterior approach goes through a gap between muscles at the front of the hip. The posterior approach goes through the back of the hip. Both place the same type of implant.
What the research shows
with 600 people found that the anterior approach gave better early recovery. The Harris Hip Score at six weeks was about 6 points higher, on a 100 point scale. Pain on the second day was slightly lower. The surgery took longer with the anterior approach, and X-ray results did not differ.
with 754 hip replacements found a higher Harris Hip Score in the first weeks with the anterior approach. The gap was gone by 12 weeks and at one year. This review found no significant difference in operation time or in complications such as fracture, dislocation, new bone growth or groin pain. The two reviews disagree on operating time. that included observational studies found the same modest early advantage.
What the Australian joint registry shows
In the Australian joint registry, hips put in through the front had the lowest overall rate of further surgery. At 9 years about 3.3 in 100 had been redone, compared with about 3.8 in 100 through the back and 4.0 in 100 through the side .
Hips put in through the front were redone less often for dislocation and infection, but more often for loosening of the stem and for a break in the thigh bone in the first few months. People who had the front approach were on average younger, lighter and healthier, which may explain part of the difference. The registry could not allow for differences between surgeons.
Risks and effort
Any approach works best in the hands of a surgeon who does it often. The reviews looked at the first weeks mainly, and they did not show a clear gap in complications.
These reviews found early benefits. They did not show a clear lasting gap. followed people for up to 10 years. People did equally well with the anterior, lateral and posterior approaches from six months onwards. More people reported problems with walking and moving after the lateral approach.
Are there restrictions after surgery?
This depends on the approach and on your surgeon. Ask what to avoid and for how long.
Does the approach change how long the implant lasts?
The trials were not long enough to answer this. In the Australian joint registry, front approach hips had a slightly lower rate of further surgery over 9 years, but more revisions for loosening and early thigh bone fracture. People chosen for the front approach were younger and healthier on average .
Does anterior hip replacement heal faster than posterior?
A little, in the first weeks. Hip scores were about 6 points higher at six weeks on a 100 point scale. The gap was gone by 12 weeks and at one year.
What are the downsides of anterior hip replacement?
One review found the operation took longer. The reviews did not show a clear difference in complications such as fracture or dislocation. The approach works best in the hands of a surgeon who does it often.
How long does it take to walk normally after an anterior hip replacement?
The trials did not report time to normal walking. Function improved faster in the first weeks with the anterior approach, and in a Melbourne study people did equally well with all three approaches from six months onwards.
