Mid-Term Results of Unicompartmental Knee Arthroplasty in Medial Compartment Osteoarthritis

Abstract

There is still controversy about the best treatment options for patients with medial compartment-involved knee osteoarthritis (OA). In cases of symptomatic medial compartment knee OA when conservative treatment is insufficient, correcting osteotomies such as high tibial osteotomy (HTO) and distal femoral osteotomy, total knee arthroplasties (TKA) or unicompartmental knee arthroplasties (UKA) are both utilized for surgical treatment [1-3]. Though TKA has been considered the gold standart of operative intervention for degenerative knee joint, many authors have shown better long term results for the latter choice, UKA, as well as good knee kinematics and function with lower complication rates. Beside this, preserving the healthy joint structures of the knee and replacing the degenerative compartment alone are the main reason for its rising popularity and led the technique to further increase of the applied frequency [3-5].
