Over the past many years, unicompartment knee arthroplasty (UKA) had been used to treat unicompartment osteoarthritis (OA) of knee. In spite of many years of experiences in performing UKA, the orthopedics scholars had not reached an agreement on it. Herein, compared to total knee arthroplasty (TKA) and high tibial osteotomy (HTO), we reviewed the controversy on the advantages and disadvantages about the usage of UKA and the indications, methods, and complications of revision of UKA. Finally, we concluded that compared to TKA or HTO, UKA might be a very good choice for us in the treatment of medial compartment knee OA.
