Trends in High Tibial Osteotomy and Knee Arthroplasty Utilizations and Demographics in Korea From 2009 to 2013
Section snippets
Patients and Methods
HTO and knee arthroplasty utilization in Korea between 2009 and 2013 using the Health Insurance Review and Assessment Service (HIRA) of Korea database, and publications of nationwide TKA registries that were published after 2009 were retrospectively reviewed.
Korea has a compulsory National Health Insurance (NHI) system with universal coverage, and the HIRA, a public agency sponsored by the Ministry for Health, Welfare and Family Affairs (MIHWFA), reviews the cost of healthcare benefits and
Results
From 2009 through 2013, in total, 29,895 HTOs, 12,589 UKAs, and 363,386 primary TKAs were performed in Korea. Of these, ~ 90% of HTO and UKA were performed in a population aged 45–74 years (range, 88–91% in HTO and 90-92% in UKA) and 97% of TKA in a population aged ≥ 55 years (range, 97-98%). Additionally, ~ 77% of HTO, ~ 85% of UKA, and ~ 90% of TKA were performed on females throughout the study period. During the same period, the overall Korean civilian population increased by 3%, whereas the
Discussion
Incidence of the knee arthritis requiring surgical procedures in young active patients and the proportion of young patients undergoing TKA are increasing. Meanwhile, advances in technology and understanding of surgical technique of HTO and UKA improve their clinical outcome and survivorship, and they are being increasingly recognized as a viable treatment option for knee arthritis in young patients. However, whether these technological advances and demographic changes affect the utilization of

As the incidence of knee OA and osteoporosis was much higher in women than in men in Korea [40,41], it was not possible to avoid this predominance. Third, the current study might not reflect entire fracture patterns of PDFFs in clinical practices.
Medial Meniscus Posterior Root Tear Does Not Affect the Outcome of Medial Open-Wedge High Tibial Osteotomy
2021, Journal of ArthroplastyCitation Excerpt :The results of this study may be somewhat difficult to generalize to the entire population. This predominance occurred because Korean women have a higher rate of HTO than do Western populations [38]. Third, there was no comparison with the group that did not receive partial meniscectomy for degenerative MMPRT, making it difficult to assess the effects of MMPRT itself.
