Indications of Partial Knee Arthroplasty: Consensus Statement

Indications and contraindications for unicompartmental knee arthroplasty (UKA) have been widely reported and debated for the past three decades. Indications and contraindications are discussed for all forms of UKA including medial, lateral, and patellofemoral, with medial UKA being the most prevalent procedure. A consensus statement was recently issued on the modern indications and contraindications for medial UKA that detailed clinical evidence for increased utilization. The primary indication for medial UKA is anteromedial osteoarthritis (AMOA), defined as bone-on-bone, Grade IV disease, or eburnated bone on the femoral condyle and tibial plateau. An additional widely accepted indication for medial UKA is avascular necrosis (AVN) involving and isolated to the medial compartment, whether spontaneous or following previous surgical intervention. Obesity, high body mass index, younger age, anterior knee pain, and involvement of the patellofemoral joint except for severe lateral facet patellofemoral osteoarthritis are no longer contraindications. Absolute contraindications are obvious joint infection, inflammatory disease, and prior high tibial osteotomy.
