BackgroundThe effectiveness of unicompartmental knee arthroplasty by lateral UKA remains poorly characterized as a limit of lateral UKA were operated for osteoarthritis (OA). However, the field of UKA surgery has rapidly expanded the usage of partly knee replacement in KOA patients with increased satisfaction, survivorship and functional outcomes. Methods A meta-analysis was conducted to evaluate the survivorship of lateral UKA with assessment with short-to midterm (10years) follow-up. Five databases were searched for eligible studies with search terms modified to the instructions of different databases. Twenty-three studies met the inclusion criteria and the pooling data were summarized in forest plots.ResultsThe implant survivorship of lateral UKA in short-term (3 year) was 96% (95%CI, 0.95-0.97, PConclusionLateral UKA is a promising method of 90% survivorship over a short- to long-term follow up. Lateral UKA is a viable option in primary treatment of OA.
