Abstract
Introduction and importance: Anteromedial osteoarthritis (AMOA) is a common knee pathology. However, the best treatment of AMOA remains unclear. Unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) are surgical options for AMOA patients who do not benefit from conservative treatment. We aimed to show an unusual treatment option where UKA and HTO are performed simultaneously.
Case presentation: We present a 52-year-old man with AMOA secondary to spontaneous osteonecrosis of the knee (SONK) and metaphyseal tibial varus malalignment, who was successfully treated with a combined UKA and HTO. His functional scores were excellent at the 5-year follow-up.
Clinical discussion: Advanced SONK that causes AMOA can be treated with osteochondral autograft transplantation (OAT), HTO, UKA, or total knee arthroplasty (TKA). Although good results have been reported selecting appropriate patients for all of these methods, the best treatment method remains unclear.
Conclusion: Although HTO and UKA are alternative treatments for AMOA, successful results can be obtained using both in individual cases.
