In 2020, six systematic reviews with meta-analyses comparing arthroscopic hip surgery and physiotherapy were published. All meta-analyses included the same three randomized controlled trials. No meta-analysis used methods suitable for the analysis of few studies (i.e. less than five). In the case of fewer than five studies and heterogeneity, a random effects model with the Hartung-Knapp-Sidik-Jonkman (HSKJ) adjustment for a maximally conservative estimate and, if reliable prior information is available, a Bayesian random effects meta-analysis should be employed. Based on our re-analysis, there is currently insufficient evidence to conclude surgery is superior to physiotherapy for FAI. Further randomized controlled trials are required to resolve the clinical question of “what is the best treatment approach for femoroacetabular impingement syndrome?”. We provide readers with tools to conduct appropriate meta-analysis of fewer than 5 trials.
