Arthroscopy combined with unicondylar knee arthroplasty for treatment of isolated unicompartmental knee arthritis: A long-term comparison

Figure 2 Twelve-year survivorship of patients between the two groups. At the last follow-up, three patients in group A received revision with a survivorship of 95%, and four in group B received revision with a survivorship of 93.1%. The outcome showed no statistically significant difference for unicompartmental osteoarthritis patients receiving the two measures (P = 0.933).
