Cohorts investigating FAI and concomitant hip OA T\u00f6nnis Grade 2 or more were considered eligible. Studies not written in English or German, below level 4 evidence, and reviews were excluded. A secondary analysis for FAI without OA stratification was conducted after the initial screening to allow identification of available non\u2010operative interventions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No study reported outcomes separately for non\u2010operative management of FAI with T\u00f6nnis Grade 2 OA or more and as such, did not fulfil the inclusion criteria.<\/jats:p><jats:p>A secondary analysis included 24 studies that reported on outcomes for non\u2010operative interventions for FAI irrespective of the degree of degeneration. Three studies investigated the efficacy of hyaluronic acid injection, 5 reports investigated corticosteroid injections, 2 studies evaluated the outcomes of hip bracing and 16 studies included a physiotherapy programme. Associations between the aforementioned interventions were analysed.<\/jats:p><jats:p>There is level I evidence supporting the efficacy of activity modification and hip\u2010specific physiotherapy for FAI and mild OA. Core\u2010strengthening exercises are prevalent amongst successful regimens in the literature. Contradictory evidence questions the efficacy of hip bracing even for short\u2010term outcomes. Corticosteroid injections have mostly failed in intention\u2010to treat analyses but may be valuable in delaying the need for surgery; further studies are warranted. Reports on outcomes following hyaluronic acid injections are contradictory.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>No evidence exists on outcomes following non\u2010operative management of FAI with concomitant T\u00f6nnis Grade 2 or more OA of the hip. Further studies are required and should explore the non\u2010operative interventions that were employed for FAI and milder OA. There is strong evidence for a hip\u2010specific physiotherapy program including activity modification and core strengthening exercises. Adjunct interventions such as corticosteroid injections and NSAID consumption may be valuable in delaying the need for surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
