Abstract
BACKGROUND: This study was conducted to assess the survivorship and clinical outcomes of cup-cage reconstruction technique in the revision of THA. METHODS: PubMed, OVID, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) up to February 2020 were searched. Studies that reported the clinical and radiological follow-up were identified. RESULTS: A total of 151 hips (145 patients) in six studies were included. The all-cause revision-free survivorship of cup-cage implant at the end of follow-up was 90.1% (136/151), with a mean follow-up of 64.4 months(range 12-135). The overall complication rate was 23.8% (36 of 151 hips), of which component problem, dislocation, infection and sciatic nerve palsy/injury were relatively common. All included studies reported improved clinical outcomes at the end of follow-up. CONCLUSION: Results suggested that revision of THA with a cup-cage has a favourable implant survivorship and clinical outcomes for the treatment of pelvic discontinuity, despite the high complications occurrence rates.
