Abstract:

Background

Clinical outcomes with high tibial osteotomy (HTO), unicompartmental knee arthroplasty (UKA), and total knee arthroplasty (TKA) are improving. However, recent trends in the use of these procedures remain unclear. We documented the (1) longitudinal trends in the use, and (2) demographics of HTO, UKA and TKA in Korea over the last 5 years, and (3) recent worldwide trends in these procedures.
Patients and Methods: We analyzed the records of HTO (n = 29,895), UKA (n = 12,589) and TKA (n = 363,386) from 2009 to 2013 in Korea, using the Health Insurance Review and Assessment Service (HIRA) of Korea database. Trends in the use and demographics of HTO, UKA and TKA, including numbers and growth rates, and age- and gender-specific utilization, were estimated. They were compared with the latest nationwide registry reports of seven Western countries.

Results

Over the last 5 years, use of HTO and UKA increased, by 210% and 138%, respectively, but that of TKA increased by only 18%. The largest increase was observed in 55–64 year olds in HTO and UKA, while the largest increase in TKA was = 75 year olds. Females commonly had a three- to seven- fold higher rate in all procedures. Worldwide, the use of HTO and UKA decreased or remained stable, whereas that of TKA increased steadily, even in younger patients. In Korea, female patients commonly represented considerably higher proportions for all procedures than in Western countries.

Conclusions

Use of HTO and UKA in younger patients and that of TKA in elderly patients increased markedly in Korea. However, HTO and UKA have not yet gained worldwide popularity. Up-to-date studies based on the uses and demographics of each country are required to establish appropriate healthcare strategies for the management of knee arthritis.
