Abstract We conducted a systematic review of published studies that evaluated the outcomes of hemiresurfacing arthroplasty (HRA) in patients with osteonecrosis (ON). A structured literature review of multiple databases referenced articles from 1950 to 2014. A total of 430 patients from 14 published studies were identified. The mean duration of follow-up after the HRA was 69 months. At the final follow-up, the mean postoperative Harris hip score was 85. Overall clinical success rate was 74%. A total of 102 (21%) revision surgeries were required after the index procedure. Our study has helped to further elucidate the outcomes of HRA in patients with ON. We believe that HRA in young, active patients is a viable option providing symptomatic relief and functional improvement.
