"Unicompartmental knee arthroplasties (UKA) or replacements (UKR) are orthopaedic procedures where either the medial or lateral articular surfaces of the knee are replaced by prostheses 1. This differs from patellofemoral arthroplasties, which replace the patellar and trochlear groove articular surfaces. Globally, UKAs make up ~7.5% (range 5.2–9.8%) of arthroplasties performed with medial replacements the vast majority (~97%) 1,2."

"In the modern-day, with the development of ultra-high molecular weight polythene, UKA has been successfully used in appropriately selected patients 5. With the advent of robotic surgery, proponents of this technique have argued that it further exemplifies the benefits of this minimally invasive, bone, ligament and soft tissue-sparing procedure 6."
"The design of the UKA consists of a femoral component, a tibial component and a meniscal bearing spacer. The different choices of the design available include the bearing design, cementing and material:"
"mixed: typically cemented tibial prosthesis and cementless femoral prosthesis; no long-term data 11"
