Background The 10th NJR report reveals that 33% of primary hip arthroplasty surgery cases are performed via the lateral approach, whereas 61% of cases are performed via the posterior approach. Despite this, evidence to inform the choice of surgical approach is lacking.

Methods Extensive searches of the literature published in any language before February 2013. Randomised, quasirandomised trials and prospective cohort studies comparing the posterior with the direct lateral approach were included.

Conclusions

We identified three randomised controlled trials and three prospective studies involving 559 participants.

In contrast to conventional teaching, it appears that the posterior approach may confer a reduction in dislocation risk, although the odds ratio did not reach statistical significance. The transosseous capsulotendinous repair of the short external rotators may account for this difference.

The posterior approach conferred a statistically significant reduction in: • Trendelenburg gait (odds ratio 0.31, P
